Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows:
Referring to fig. 1-4, a vacuum circuit breaker includes a frame, an operating mechanism 2 disposed in the frame, a transmission mechanism, and a plurality of vacuum interrupter poles.
The operating mechanism comprises a pair of oppositely arranged side plates 21 and a main shaft 22, and the main shaft 22 is rotatably arranged between the two side plates 21 in a penetrating way; the main shaft 22 rotates to drive the transmission mechanism to act so as to realize the switching on and switching off of the circuit breaker.
A micro switch group 3 is fixedly arranged on the outer side of the side plate 21, and the micro switch group 3 comprises at least two micro switch units 32; specifically, the micro switch group 3 is an integrated micro switch group, and the micro switch group 3 includes a housing 31 and the micro switch unit 32 disposed in the housing 31; the micro switch units 32 can be selectively installed in a cavity formed by the housing 31, and the number of the micro switch units 32 is selected according to actual requirements, in this embodiment, the number of the micro switch units 32 is two.
One end of the main shaft 22 is provided with a driving component acting on the micro switch group 3; the driving assembly includes a pressing portion 41 and a transmission plate 42.
the pressing part 41 is fixedly arranged on the main shaft 22, specifically, the pressing part 41 is a cam, a through hole is arranged in the middle of the cam, the cam is sleeved on the main shaft 22 through the through hole, a retainer groove 221 is arranged on the main shaft 22, and a retainer ring 222 is arranged in the retainer groove 221; the cam is disposed between the two retainer grooves 221 and is fixed to the main shaft 22 by the two retainers 222.
the driving plate 42 swings relative to the side plate 21; specifically, the driving assembly further includes a mounting shaft 5, the mounting shaft 5 rotates relative to the side plate 21, the mounting shaft 5 may be rotatably disposed on the side plate 21, may also be rotatably disposed on the housing 31, and may also be rotatably connected to the side plate 21 and the housing 31 at the same time; the transmission plate 42 is fixed on the installation shaft 5, and the installation shaft 5 rotates along with the swing of the transmission plate 42; specifically, the transmission plate 42 includes an installation portion 421, the installation portion 421 is respectively bent toward two opposite ends to form a pressed portion 422 and a driving portion 423, the pressed portion 422 is opposite to the pressing portion 41, and the driving portion 423 is opposite to the micro switch group 3.
the main shaft 22 rotates to drive the pressing part 41 to rotate and act on the pressed part 222 of the transmission plate 42, so as to drive the transmission plate 42 to swing, and therefore the driving part 423 of the transmission plate presses the micro switch set 3, namely at least two micro switch units 32, and transmits the switching-on/off signals of the vacuum circuit breaker to the micro switch set, so that the purpose of signal acquisition is achieved, and then information is respectively transmitted to required area occasions such as comprehensive protection, intelligent control, remote monitoring and the like. Because the pressing portion 41 adopts the cam structure, when the driving plate 42 presses the working end of the micro switch unit 32, the motion curve of the micro switch unit 32 is smoother, and the micro switch unit 32 is more reliably switched.
