The invention relates to a frame breaker energy storage transmission device which solves the problem that energy storage can be performed on an existing frame breaker only by rotating an operation handle with much power by workers. The frame breaker energy storage transmission device comprises a first ratchet wheel arranged on a breaker transmission shaft, a first pawl and an operation handle, the first pawl is arranged on a side plate of a breaker and matched wit the first ratchet wheel, a first gear in linkage with the breaker transmission shaft and a ratchet assembly rotationally matched with the transmission shaft are arranged on the transmission shaft, a clutch device is arranged between the operation handle and the ratchet assembly, the ratchet assembly comprises a second gear in linkage with the gear assembly and a second ratchet wheel matched with a second pawl on the clutch device, and the gear assembly is in linkage with the first gear. The breaker can store energy with less operation force of workers according to different transmission ratios, and thus labor intensity of the workers is reduced. The frame breaker energy storage transmission device further has the advantage of being simple and reasonable in structure and light and convenient to operate.
Description
technical field [0001] The invention relates to a frame circuit breaker, in particular to an energy storage transmission device for a frame circuit breaker. Background technique [0002] The existing energy storage transmission device of a circuit breaker includes a second ratchet arranged on the transmission shaft of the circuit breaker, a detent and an operating handle arranged on the side plate of the circuit breaker to match the ratchet, and the ratchet is driven to rotate by rotating the operating handle. , so as to drive the transmission shaft to rotate to realize the energy storage of the circuit breaker. When the circuit breaker has a large capacity, the compression force of the energy storage spring is nearly 10,000 Newtons, and the force required to turn the operating handle will also increase accordingly. Manual operation is very laborious, and some transmission mechanisms will change the rotation direction of the transmission shaft. The structure of the energy s...
