In side plate 1 arranged outside external release interface 10 and energy storage motor interface 11 are arranged.
Being provided with cam 9 at power transmission shaft 22 two ends in side plate 1 outside exports as transmission.
Operation principle of the present invention is as follows:
The divide-shut brake operating principle:
In the closing operation process, the brake cam 6 on the retainer 59 place assemblies drives gangbar 7 and the push rod 8 that resets simultaneously, as shown in Figure 4, promotes combined floodgate dropout plate 53, makes it get back to the front position of closing operation, thinks that closing operation is prepared next time.The push rod 8 that resets also links with on/off switch state indication piece, makes indication piece show " circuit breaker closes a floodgate " after finishing closing operation; Meanwhile, brake cam 6 arranged outside have specific irregular cam groove 61, gangbar 7 one ends are stuck in power transmission shaft 22 both sides, and have a projection 71 to be arranged on actively 61 li of brake cam grooves, and the other end of gangbar 7 is flexibly connected with an end of the push rod 8 that resets.Brake cam groove 61 moves by driving gangbar 7, thereby drives large dropout plate 57, its afterbody is slowly lifted synchronously, until the plate 57 of threading off greatly resets after finishing closing operation.This moment, operating mechanism can carry out sub-switching operation at any time.
Sub-switching operation is driven by separating brake push rod 13, and 52 rotations of separating brake dropout semiaxis allow open position, and separating brake dropout plate 54 loses support, and STATEMENT OF FEDERALLY SPONSORED 2 552 and STATEMENT OF FEDERALLY SPONSORED 3 553 move upward, and course of action thereafter is consistent with the closing operation Principle of Process.
Minute, lock operation public same release mechanism, reduced operating mechanism quantity, so that operating mechanism more compact structure, volume is less, can realize simultaneously the interlocking of on/off switch operating sequence, that is: when combined floodgate/separating brake action does not finish, operating mechanism does not allow minute/closing operation, and this is that other operating mechanisms are not available.
The operating mechanism both sides have been installed 2 cams 9 symmetrically, rotate with main shaft in mechanism's on/off switch operating process, thereby drive the drive link assembly, and promotion pole pull bar is done accordingly and moved up and down, and namely the vacuum interrupter moving contact carries out closure and disjunction action.
As shown in Figure 6, energy storage component 2 is comprised of Manual stored energy organization 21, travelling gear 1, travelling gear 2 24 and coil spring box assembly 26.During energy storage, pull manual lever 211, drive Manual stored energy organization 21 and travelling gear 2 24 rotations, travelling gear 2 24 band nutating gears 1 rotate, the coil spring box assembly 26 that is connected and fixed with travelling gear 1, also begin to rotate, to the energy storage of crispaturaing of dress scroll spring 25 within it, until energy storage stops after finishing thereupon.
As shown in Figure 7 and Figure 8, when coil spring box assembly 26 turns to ad-hoc location in the thermal energy storage process, energy storage control panel 271 breach arrive the below of energy storage latching member 272, energy storage latching member 272 is under the effect of the power of back-moving spring, fall in control panel 271 breach and move downward, thereby one time drivening rod 273, semiaxis 274 and push rod 275 rotate, the rear semiaxis 274 that puts in place gets out of the way locked position of coupler, combined floodgate dropout plate 53 can be passed through, otherwise, the dropout plate 53 that then closes a floodgate can't pass through, and has realized that namely circuit breaker only can carry out the blocking function of closing operation after energy storage is finished; Push rod 275 is used for removing energy storage motor, removes the driving coupling of energy storage motor and stored energy mechanism after energy storage is finished.272 pairs of energy storage control panels 271 of energy storage latching member are braked simultaneously, and this moment, stored energy operation no longer was allowed to, thereby have determined the position of the energy storage completion status of circuit breaker.
When circuit breaker was finished closing operation, main shaft drove the STATEMENT OF FEDERALLY SPONSORED of switching-on mechanism and rotates, and STATEMENT OF FEDERALLY SPONSORED can be lifted energy storage latching member 272 after closing operation is finished and reset, and lock release can enter next stored energy operation circulation.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present invention that appended claims limits; in the form and details the present invention is made a variety of changes, be protection scope of the present invention.
