The invention discloses a long-stroke hybrid quick operating mechanism for a high-voltage circuit breaker; the long-stroke hybrid quick operating mechanism comprises a permanent magnet holding assembly, an electromagnetic repulsion assembly, an opening spring assembly, a closing spring assembly, an energy storage assembly and a support frame; the permanent magnet holding assembly is used for realizing the holding of opening and closing positions of the circuit breaker; the electromagnetic repulsion assembly is used for generating a pulse force, overcoming a closing suction force or an opening suction force of the permanent magnet holding assembly, and enabling closing and opening of the mechanism to be rapidly released; the initial closing and opening operation speed of the circuit breaker is increased through the pulse force, and the closing and opening time of the circuit breaker is shortened. The opening spring assembly is used for providing main opening power when the circuit breaker moves to a long stroke interval; and the closing spring assembly is used for providing main closing power when the circuit breaker moves to a long stroke interval. Long-stroke rapid operation of the high-voltage circuit breaker can be realized.
Description
technical field [0001] The invention relates to the technical field of high-voltage circuit breakers, in particular to a long-stroke hybrid fast operating mechanism for high-voltage circuit breakers. Background technique [0002] With the continuous growth of the national economy and the rapid development of high-end manufacturing, the scale of the power system continues to expand, and the large-scale and centralized access of new energy systems. Industrial and domestic electricity consumption has put forward higher requirements for the safe and stable operation of the power system and the quality of power supply. High-voltage circuit breakers are one of the key equipment to realize power system control and protection. On the one hand, IEEE Std1564 TM -2014 pointed out that when the short-circuit fault removal time of the circuit breaker is within 20ms, the power supply quality of most loads will not be affected; Occurrence of offline accidents. The rapid and reliable remo...
