The invention discloses a compact high-voltage compartment dedicated to a wind power box, which comprises a cabinet body, a plurality of space structures are formed in the cabinet body, and an internal arc pressure release channel is opened at the upper end of the cabinet body; the space includes an integrated There is a first space of the vacuum circuit breaker, an operation interlock mechanism is arranged in the first space, and the operation interlock mechanism is respectively connected with the grounding switch and the isolating switch; the isolating switch is located on one side of the vacuum circuit breaker, and the grounding switch is located in the first space In the second space above; the grounding switch is connected to the arrester and the current transformer; the fuse that the current transformer passes through is connected to the voltage transformer, and the cabinet body is provided with a wall bushing, the current transformer and the wall bushing A high pressure sensor is arranged between them, and a movable sealing plate is arranged on the cabinet body. The compact high-voltage compartment dedicated to the wind power box transformer improves the completeness and reliability of protection, measurement and control functions, has high safety performance, and has a small overall structure to meet the needs of miniaturization development.
Description
technical field [0001] The invention relates to the field of power generation and distribution, in particular to a compact high-voltage compartment dedicated to a wind power box transformer. Background technique [0002] With the development of new energy technology, the capacity of a single wind power generation unit has increased rapidly. Therefore, the capacity of the box-type substation used for voltage boosting, measurement, control and protection between each wind tower and the 35Kv collector wire has also increased. Larger volume, installation and transportation, use and maintenance and transformation of early equipment are greatly unchanged, and the safety performance and stability performance also need to be improved. Therefore, the variable structure of the wind power box, which is safe, reliable, easy to maintain, and meets the needs of miniaturization development, has become an urgent need for the wind power generation industry.
