<p> What about Zhuzhou Tianyuan Transformer Manufacturer? The cores of this series of energy-saving transformers are laminated with cold-oriented high-quality silicon steel sheets, and the coil structure adopts cylindrical, oval and rectangular cylinders. Small size, excellent performance, safe and reliable. Work Course Zhuzhou Tianyuan Marine Transformer sells goods for a fraction of the cost. Although there are many low-quality buyers of marine transformers, we cannot question the practicality of marine transformers. So how many secrets are there in Transformers? Why are you often praised, but you still say you are worth it? In the smaller version, we will learn about the characteristics of expensive marine transformers. Quality inspection report When the transformer suffers a sudden short circuit, both the high and low voltage sides will receive a large short-circuit current. In a short time before the circuit breaker is too time to open, the short-circuit electricity is proportional to the square of the current. The electric force will act on the transformer. Winding, this electric force can be divided into radial force and axial force. During a short circuit, the radial force acting on the winding will subject the high-voltage winding and the low-voltage winding will be stressed. Because the winding is circular, a circular object is more easily deformed under pressure than under pressure. Therefore, the low-voltage winding is more easily deformed. The axial force generated during a sudden short circuit compresses the windings and causes axial displacement of the high and low voltage windings. The axial force also acts on the iron core and the clamp. The condition of testing the standard Jiyuan is no problem for the villages in the plains, but it is really difficult compared to our remote mountainous areas. Because some villages do not live in a concentrated way, the mountain family Mito, especially the geographical location is very bad, the whole village saw stones but no soil. For this reason, the author recommends that the construction masters take the facts as a basis and split the method, that is, try to select multiple small transformers to install at multiple locations. Commitment and trustworthy application The plane transformer has been widely used in communications, notebook computers, automotive electronics, digital cameras, and digital TVs in just over 10 years since its inception. For example, a DC-DC converter with a power range of 5 to 60W made by a planar transformer, and Zhuzhou Tianyuan Transformer Manufacturer, has been applied to card-type on-board power supplies for telecommunications systems. Due to the special electrical and mechanical environment of automobiles, stricter requirements are imposed on transformer design and technology. Planar transformers are used in DC-DC converters for xenon arc lamp ballasts and have been used in mid-range cars. In short, Zhuzhou Tianyuan Transformer Manufacturers. In short, due to electromagnetic abrasion, mechanical wear, chemical action, atmospheric corrosion, electrical corrosion, and improper maintenance and management of transformers during operation, various abnormal operating phenomena and more serious fault phenomena will occur. Only by strengthening the operation management of all aspects of the transformer can the transformer reach a healthy operating level. Equipment maintenance According to relevant data statistics, the total loss level of the SC (B) 9 series has dropped by 15-20% compared with the introduced SC series, of which the no-load loss has dropped by 25%. The systematic research on noise has improved the mastery of noise generation. And implement its results on the new series of SC (B) 8 and SC (B) 9 products. The noise of the SC (B) 9 series products is 15-20% lower than the original SC series. Management Department </ p> <p>

</ p> <p> How does Zhuzhou Tianyuan Transformer Manufacturer's main insulation and inter-turn insulation failure of windings? Everyone knows that transformers are composed of iron cores and coils, and coils are windings, which are overloaded for long periods of time, or have poor heat dissipation conditions. Either the use time is long, these factors will cause the winding insulation to age and cause brittle cracks, which will reduce the winding's electrical strength; the transformer cannot be without faults, and its faults are mostly overvoltage short circuits. Short-circuit failure will force the winding to deform and cause insulation defects. In case of voltage fluctuations, insulation breakdown may occur; the oil pillow function of the transformer is to reduce the temperature generated by the operation of the transformer. In rainy days, it is unavoidable that rainwater flows into the oil pillow, which will greatly reduce the insulation strength of the transformer winding and cannot withstand the allowable overvoltage, otherwise it will cause the winding insulation to be broken down; when the transformer receives external current, the high voltage winding The high-strength current will be processed at the reinforced section, and then run into the low-voltage winding. During this process, the turn-key package will block the oil passage in the oil pillow due to insulation, resulting in poor heat dissipation and overheating the winding insulation. Aging, breakdown short circuit occurs; due to the imperfect lightning protection facilities of the transformer, under thunderstorm conditions, the coil insulation will be broken due to the transformer overvoltage. It is well known that in operation, the transformer is inevitably affected by the short circuit of the outlet or the short-circuit fault in the near zone. During transportation and installation, it may also be impacted by impact. Under these impact forces (including electric and mechanical forces), the transformer windings may be deformed. For example, axial and radial dimensional changes, displacements, distortions, bulging, and so on. As a result, turn-to-turn short-circuits can result, which ultimately damage the transformer. The types and characteristics of common transformers The classification of commonly used transformers can be summarized as follows: Divided by the number of phases: Single-phase transformers: used for single-phase loads and phase transformers. Check the gas operation signal by using the air pump method. Check the heavy gas protection circuit with the action probe or short-circuit contact. The connection is correct and good, and it trips. The transformer with oil circulation cooling should start and stop the circulation pump test. The gas relay should not action. Zhuzhou Tianyuan 1 steady-state ratio differential protection Due to the different transformation ratios and connection groups, when the power transformer is running, the current magnitude and phase on each side are also different. These effects must be eliminated before constituting the relay. The TA of the converter transformer is generally installed on each side winding, so the current phases of the primary and secondary windings are the same, so only the effect of the transformation ratio needs to be compensated. The following premise is that the differences in amplitude and phase on each side of the transformer have been eliminated. Equipment management 3 Physical characteristics The planar transformer has the characteristics of small size, usually between 0.325 inches and 0.750 inches, which is quite attractive for occasions where the internal space of the power supply is severely restricted. Since the transformer usually needs long-term repair after being short-circuited, two measures can be taken to prevent the transformer from getting wet: one is to tighten the transformer cover before the end of each day, and the other is to use a vacuum pump to vacuum the transformer to remove the surface Free water. S body. On good days of operation, use dry nitrogen or dry air to release the vacuum. After maintenance, it can be directly put into hot oil circulation. Take precautions against rain at the end of the transformer's daily work. After the work is finished, the transformer is dried by hot oil spraying, which usually takes 7-10 days. Comprehensive quality management Luohe's new curtain fan air cooling system reduces the noise, uniform cooling and good effect; small size, small space, does not exceed the outline size of the transformer body; small fan capacity, distribution transformer fans below 2500kVA only 180W ~ 540W, and uses a single-phase AC220V power supply. However, it should be noted that this power should be taken from the circuit breaker in the low-voltage MCC or PC power distribution panel, and not directly from the low-voltage outgoing busbar of the transformer. ZSG series rectifier transformers are widely used in industrial charging, DC lighting, DC excitation, electroplating, power transmission and other fields. They have the advantages of small size, light weight, simple maintenance and reliable operation. Good cost coils are made of copper wire winding, copper wire insulation grade and other basic specifications are the same, but the brand is different, some are cheap, some are expensive, and expensive materials are reliable in both process and quality.

</ p> <p> What about Zhuzhou Tianyuan transformer manufacturers? When transformers are used in switching power supplies, the current waveform flowing through the windings is not a sine wave and contains high-order harmonics. Therefore, it is not enough to consider only the effect of the fundamental wave. The appropriate approach is to first find the harmonic components of the current waveform, and then the winding losses of the corresponding current harmonic components. High-quality, low-price Huaxing special transformer marine cores and coils are strictly in accordance with customer requirements, and the product is made of high-quality materials, so that the transformer can meet the performance while achieving the characteristics of small size, light weight, beautiful appearance and so on. In the case of transformer operation, temperature rise is unavoidable, but Huaxing Special Transformer fully considers the heat dissipation problem in the structure, so that its heat dissipation performance is excellent, and it has good waterproof and moisture resistance performance. help. Safety and Hygiene According to the theoretical analysis of the transformer, assuming that the primary induced potential is E1 (volt), then: E1 = KfBm The effect of the size of the water nozzle diameter on the leakage current; under the conditions of the same voltage, the same resistivity of water, and the same distance, use water The leakage current of the water column is smaller than that of the large diameter. When direct current water is used to extinguish a fire on a fire site, if the voltage is relatively high or the resistivity of the water is relatively small, water should be used in order to improve the degree of safety. When it is necessary to increase the amount of water used for fire fighting, the amount of water can be increased without using large-caliber water. Gas protection inspection cycle All gas protection inspections are performed in conjunction with transformer overhaul. 1-2 external and insulation inspections and the entire group inspection are performed every year. Every 2 to 3 years, the internal and mechanical parts of the gas relay running transformer are inspected. The working principle of honesty and mutual benefit transformer: winding the pair or pair of coils (single phase or phase) on the closed iron core, the coil connected to the power source is called the original coil, and the coil connected to the load is called the secondary coil. When the primary coil is connected to AC power, there is a current in the primary coil, which generates an alternating magnetic flux Φ in the closed iron core. This alternating magnetic flux Φ passes through the primary coil and the secondary coil at the same time. According to the principle of electromagnetic induction, The original coil will generate self-inductive electromotive force, and the auxiliary coil will generate mutual inductive electromotive force. At this time, when a light bulb is connected to the auxiliary coil, the electric lamp will emit light, and a current will flow in the circuit. The altitude does not exceed 1000m; the ambient temperature is not higher than + 40 ° C and not lower than -20 ° C; the relative humidity of the air is not greater than 95% (at + 25 ° C); Dangerous places; no strong bumps, vibrations and environments with an inclination of no more than 15 ° from the vertical plane; no corrosive gases and vapors of metals and insulating materials; no dripping and water immersion. </ p>
