Problems solved by technology
Due to the low efficiency of the transmission structure, the closing time of the circuit breaker is long and the characteristics are unstable, which reduces the reliability of the high-voltage circuit breaker
The existing spring operating mechanism cannot meet the needs of the national power system. With the continuous increase of system capacity, the continuous increase of transmission voltage, and the advancement of circuit breaker technology, the State Grid needs a spring-operated closing device with stability and high output power. mechanism

The invention discloses a spring operation closing mechanism which comprises left and right wall plates arranged in parallel. A support block A, a support block B, an opening spring tube, a spring tube flange and a connecting plate are fixed through bolts between the left wall plate and the right wall plate. An output shaft runs through the space between the left wall plate and the right wall plate. The output shaft is in transmission connection with a transmission shaft. An output inner crank is fixedly arranged on the transmission shaft. The output inner crank is linked with a transmission inner crank. A connecting plate is arranged between the output inner crank and the transmission inner crank. A closing spring tube is horizontally placed at the middle and lower parts between the leftwall plate and the right wall plate and is bolted. The spring tube flange passes through the closing spring tube, is placed on the right tail end thereof, and is bolted. A large closing spring sleevesthe closing spring tube. A small closing spring is sleeved in the closing spring tube.
Description
technical field [0001] The invention relates to the field of spring operating mechanisms, in particular to a spring operating closing mechanism. Background technique [0002] The spring operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and is an important part of the high-voltage circuit breaker. The closing operation of the high-voltage circuit breaker is realized through the operating mechanism. [0003] At present, the spring operating mechanism used in UHV circuit breakers generally has the problem of low output power. Due to the low efficiency of the transmission structure, the closing time of the circuit breaker is long and the characteristics are unstable, which reduces the reliability of the high-voltage circuit breaker. The existing spring operating mechanism cannot meet the needs of the national power system. With the continuous increase of system capacity, the continuous increase of transmission vo...
