Abstract

The invention discloses a cabinet for a medium-voltage hybrid DC circuit breaker based on a magnetic coupling transfer principle, comprising a front compartment, a rear compartment and a side compartment that are independently arranged, wherein the rear compartment is located in a Behind the front compartment, the side compartment is located on one side of the front compartment. The cabinet body of the medium-voltage hybrid DC circuit breaker based on the magnetic coupling transfer principle provided by the present invention has a clear design structure, clear division of compartments, flexible space layout, and is conducive to the expansion of functions, and can be customized according to various space and function requirements. Cabinet structure of medium voltage hybrid DC circuit breaker adjusted accordingly. In addition, the floor area is small, and the manufacturing cost is saved. The invention also discloses a medium-voltage hybrid DC circuit breaker based on the magnetic coupling transfer principle using the above-mentioned cabinet.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a medium-voltage hybrid DC circuit breaker and its cabinet based on the principle of magnetic coupling transfer. Background technique [0002] With the adjustment of the country's energy structure, fossil energy continues to decrease and the environment is deteriorating. It will be the general trend to develop renewable clean energy to replace fossil energy. The multi-terminal DC transmission system and DC grid technology based on conventional DC and flexible DC are one of the effective technical means to alleviate the current shortage of traditional primary energy, environmental degradation, and to solve the problems of new energy grid integration and consumption. However, the two technical bottlenecks of strong breaking capacity and fast breaking speed have greatly restricted the development of DC transmission. [0003] Compared with mechanical and solid-state...
