High-low pressure transformation device realizes that lead is fixed including the fixation of high-voltage switch gear, high-voltage terminal wall bushing, arrester, sensor, insulator to copper busbar, and arrester is in leading-out terminal(In cable cabinet)Assembling.The 35kV transformation cabinets that voltage electricity transforming devices for use is designed using our company, transformation cabinet mainly uses high-voltage alternating isolated vacuum load switch --- fuse combined electric apparatus, is protected at high-voltage terminal end from 35kV arresters.High-voltage board links to form the anti-interlocking protective device of safe five using sensor electromagnetism.Transition of the major loop copper bar between high-voltage board and outlet terminal is realized using 35kV high pressure sensors.
Transformer high-voltage pressure regulation uses oil immersed type No-load changer shunting switch, loaded on transformer body top, on the conservator of oil level gauge, fuel feeding valve gas relay loaded on transformer, the outside of radiating fin of transformer and the open outside the enclosure portion of transformer body, low voltage outlet terminals and high-voltage outlet terminal loaded on transformer connecting flange faces.
High-low pressure transformation device is installed additional in the high-pressure side of transformer and low-pressure side, wherein transformer high-low voltage outlet mode all goes out formula using side, high pressure uses high-voltage alternating isolated vacuum load switch --- fuse combined electric apparatus transformation device, low pressure uses the compact transformation device with breaker as main switch, high-low pressure is directly connected with transformer, forms compact case structure changes.Operation and change of fuse safety easy to maintenance, there is independent maintenance room in addition.Transformer high-voltage uses side outlet, transformer high-voltage wire outlet uses 35kV pure porcelain casing tubes, directly with high-voltage alternating isolated vacuum load switch --- fuse combined electric apparatus are connected with copper bar in high-voltage board, and copper bar connection distance is near, low pressure is using 690V pure porcelain casing tubes and high-voltage outlet terminal side by side loaded on transformer connecting flange faces outside, directly it is connected with copper bar with low-voltage cabinet, saves assembly space.
The case top that case becomes installs two pieces of solar panels additional, and solar energy electricity is operated for high and low voltage switch, and case becomes various switches, illumination, the power supply of state instruction, so as to ensure that in the case of calm generating, remains to operate high-low pressure transformation device.
High-voltage terminal sets independent assembling Maintenance Room, is easily installed maintenance, improves the security of operation.
Case becomes column and is connected with the existing horizontal plane of base, has vertical plane to connect again, and case change shell bulk strength is very high, and wind loading rating is strong, and becoming compared with prepackage type case has very prominent wind loading rating.
The beneficial effects of the invention are as follows wind-power electricity generation can be applicable, compact conformation, manufactures easier, safeguards that observation is convenient, make full use of the environment of wind power plant, solar power generation is effectively utilized, strengthens radiating effect, effectively using solar power generation, become switch to case in the case of used by ensureing to operate, equipment dependability is improved, space is saved floor occupying area and use, cost of investment is reduced.The design of this case structure changes is particularly suitable for that northern area is high and cold, scorching weather.
