Within the scope of the utility model, the scope of protection claimed by the present utility model is defined by the attached claim and its equivalent. Reasons for Zhuhai with excellent quality and treatment measures: The insufficient length of the anchor bolts is caused by the improper exposed length of the anchor bolts during the construction of the foundation embedded parts; the anchor bolts are rusted, which is improper protection of the finished products, and the storage of the anchor nuts and pad Caused by improperness; the pad does not fit tightly with the tower foot plate, which is mainly caused by the interference between the pad and the tower foot plate. In order to avoid the above-mentioned defects, the height difference of the foundation top surface, the exposed height of the anchor bolts, and the pre-deflection value of the corner tower should be checked on site before the tower building operation to ensure that there is no problem before the tower building operation is carried out. Construction shall not be forced; severely rusted nuts shall not be used in engineering, and those that are floating on the surface shall be derusted and spray-painted to prevent further corrosion; if the blocks are in conflict with the welding seam, the blocks shall be appropriately cut.

Home recommendation
[Technical Field]  The present invention belongs to the field of power transmission and distribution, and particularly relates to a line structure and a line structure. It is recommended to consult the differential protection and gas protection to cooperate with each other to complete the task of protecting the main transformer. Operating experience has proven that when internal faults occur in the transformer, both differential protection and gas protection can be reflected. When the internal fault of the transformer (such as a short between layers), the oil flow rate and the increase in the secondary current are reflected, it is possible to activate the two types of protection. As for which kind of protection works first, it must also be decided by the nature of the fault . Before the gas relay is installed and put into operation, open the communication valve between the oil pillow and the fuel tank to fill the gas relay with oil, and at the same time open the exhaust hole to air the gas relay until the exhaust hole continuously emits oil. Trustworthy technology implementation elements: The utility model aims to solve the above problems, thereby providing an angle steel tower installation structure with high installation efficiency, high accuracy, and convenient operation. A mobile substation refers to a substation used to temporarily supply power to important users or construction units. Electrical equipment is installed on trains or cars with small capacity. [Background technology]  Two power plants, two generating units, two outgoing lines plus a backup power lead, a substation frame lifting device, which includes a hoop U-shaped channel steel support rod (steel material), a tensioner hanging ring 5; U Both ends of the section channel 2 are welded to the hoop 1. The U channel channel 2 is fixedly connected to the lower end of the support rod by bolts (the U channel channel 2 is provided with a bolt hole, and the lower end portion of the support rod is provided with a bolt hole. In this embodiment, four bolt holes are used, and four bolts are connected;), the upper end portion of the support rod is fixedly connected with a hanging ring thread tensioner 4 hanging on the hanging ring 5. The angle between the cement rod and the vertical direction is 5 °. To achieve uniform stress during the lifting process, the connection angle between the hoop and the support rod should be 95 °. The diameter of the hoop should be slightly smaller than the cement rod, and the bolt can be firmly fixed to the cement rod after tightening, so the diameter is determined to be 30cm. The length of the support rod is d = 2 meters. Using two substation frame lifting devices in common use, Zhuzhou Fuling substation frame, the hoop of each substation frame lifting device is fixed to the cement rod, and the end of the frame is lifted by the tensioner; the hoop of the first substation frame lifting device It is fixed on the first cement rod, and the other end of the frame is lifted by the thread tensioner. Overhead lines are usually required to connect the host group and the booster station. In order to save water, inland power plants mostly adopt the cooling method of circulating cooling water towers, and the cooling water towers are arranged near row A of the main plant to shorten the length of the circulating water pipes. At this time, the circuit overhead cooling tower connecting the main plant and the booster station. If the circuit line groups are arranged in order from the top to the bottom in the form of a tower, the difference in lead height is too large, resulting in inconvenient connection and high cost. Therefore, conventional loop overhead lines are constructed side by side. However, the width of each frame is about 30-45 meters, and the floor span is about 90-135 meters, which results in a large power plant and a large investment, and the distance between the two cold dewatering towers is increased, increasing operating costs. Excellent service In addition, the boost station is also connected to DCS and NCS for data communication and secondary equipment. Preferably, a rubber strip is fixedly connected to the left side of the movable plate, and the end of the rubber strip remote from the movable plate is fixedly connected to the upper surface of the buffer plate.
