Requirements of High Voltage Circuit Breakers for Transmission and Distribution in China
Urban power grids, rural power grids and catenary networks are the main components of China's transmission and distribution grid. Among them, the transmission capacity of urban power grids accounts for 48% of the national total, the transmission capacity of rural power grids accounts for 51% of the national total, and the catenary power transmission accounts for 1% of the national total. In our country to comprehensively strengthen the construction of the national grid environment, the quality of high-voltage circuit breakers has become a high concern of power workers. Now let us look at China's transmission and distribution grid high voltage circuit breaker requirements.
Urban Power Grid High Voltage Circuit Breaker Requirements
(1) to promote the use of gas-insulated metal-enclosed switchgear in the city center.
(2) The use of oil-free circuit breakers in the construction and renovation of urban power grids, vigorously promote the ring network power supply.
Rural Power Grid High Voltage Circuit Breaker Requirements
As the high-voltage switchgear for rural power grids is outdoors, it must meet the insulation requirements, and the power equipment should have good performance, compact structure, high reliability and can adapt to the environment.
Contact with the grid on the high-voltage circuit breaker requirements
(1) high-voltage circuit breakers must have more slang inflammatory fan bite bath in the transport system for overhaul, it is necessary to minimize the impact.
(2) high-voltage circuit breaker switch to single-type switch.
