What is the installation equipment of the transformer on the power installation project
It is composed of oil immersed transformer, low voltage outlet cabinet, lightning arrester, conductor, concrete pole, insulator, hardware and iron accessories, concrete prefabricated components. Construction method:
Installation of lightning arresterMost of the external factors that affect the operation of distribution transformers are from lightning accidents. Therefore, the transformer equipped with lightning protection devices, should be used in the synthesis of metal oxide arrester without gap insulation, the power frequency voltage withstand capability, good sealing, protection characteristics.
Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.
Installation of 10kV distribution transformer platformMost of the installation and use of double column transformer (capacity of less than 500kVoA), spacing of two rod is 2m, less than 20mm in the transformer tilt rod, power distribution transformer platform with two channel 2.4m is fixed on the two poles, the bench from the ground is not less than 2.5m, the gantry tilt should not be large in high 1/100. The bottom of the transformer is fixed with 4 screws on the platform, and the high and low voltage of the transformer should be equipped with dust cover. In addition, the installation of iron parts are galvanized, and more than 100kVoA transformer to install a disconnecting switch.
