Operation principle of the present invention is as follows:
Divide-shut brake operating principle:
Retainer 59 has two specific flanges 591, allowing operating mechanism stop at corresponding combined floodgate or open position when operating, depending on the position that retainer 59 stops.As shown in Figure 5, the course of work of closing operation is as follows: when operating mechanism is in the state of separating brake energy storage, promote combined floodgate push rod 12, namely combined floodgate dropout semiaxis 51 rotates and allows open position, combined floodgate dropout plate 53 loses support, the right side quadric chain of the third level release mechanism at its place starts action, gangbar 1 and gangbar 3 553 move upward, large dropout semiaxis 56 in the release mechanism of the second level is rotated counterclockwise thereupon, until be separated with large dropout plate 57, large dropout plate 57 lifts under the precompression of retainer 59, rotor 58 of triping in final first order release mechanism on large dropout plate 57 lifts, retainer 59 loses the spacing freedom of entry motion state of rotor 58 of triping, rotate along pointer under the driving of energy-stored spring 25, complete closing operation, the motion of final retainer stops at flange 591 place of open position, and operating mechanism is for "on" position,
In closing operation process, the brake cam 6 on the assembly of retainer 59 place drives gangbar 7 and reset push rod 8 simultaneously, and as shown in Figure 4, promote combined floodgate dropout plate 53, the position before making it get back to closing operation, thinks that closing operation is prepared next time.Reset push rod 8 also links with on/off switch state indication piece, makes indication piece show " circuit breaker closes a floodgate " after completing closing operation; Meanwhile, brake cam 6 arranged outside has specific irregular cam groove 61, gangbar 7 one end is stuck in power transmission shaft 22 both sides, and has a projection 71 to be arranged on brake cam groove 61 li actively, and the other end of gangbar 7 is flexibly connected with one end of reset push rod 8.Brake cam groove 61 moves by driving gangbar 7, thus drives large dropout plate 57, and its afterbody is slowly synchronously lifted, until large dropout plate 57 resets after completing closing operation.Now operating mechanism can carry out sub-switching operation at any time.
Sub-switching operation is driven by separating brake push rod 13, and separating brake dropout semiaxis 52 rotates and allows 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 is thereafter consistent with closing operation Principle of Process.
Point, the public same release mechanism of lock operation, decrease operating mechanism quantity, make operating mechanism more compact structure, volume is less, the interlocking of on/off switch operating sequence can be realized simultaneously, that is: at the end of the action of combined floodgate/separating brake does not have, operating mechanism not to allow point/closing operation, and this is not available for other operating mechanisms.
Operating mechanism both sides have installed 2 cams 9 symmetrically, with main axis in mechanism's on/off switch operating process, thus drive drive link assembly, and promotion pole pull bar does and moves up and down accordingly, and namely vacuum interrupter moving contact carries out closed and disjunction action.
As shown in Figure 6, energy storage component 2 is made up 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, Manual stored energy organization 21 and travelling gear 2 24 is driven to rotate, travelling gear 2 24 is with nutating gear 1 to rotate, the coil spring box assembly 26 be connected and fixed with travelling gear 1, also start to rotate thereupon, dress scroll spring 25 within it crispaturaed energy storage, until energy storage complete after stopping.
As shown in Figure 7 and Figure 8, when in thermal energy storage process, coil spring box assembly 26 turns to ad-hoc location, energy storage control panel 271 breach arrives the below of energy storage latching member 272, energy storage latching member 272 is under the effect of the power of back-moving spring, to fall in control panel 271 breach and to move downward, thus drivening rod 273, semiaxis 274 and a push rod 275 rotate, after putting in place, semiaxis 274 gets out of the way locked position of coupler, combined floodgate dropout plate 53 can be passed through, otherwise, then combined floodgate dropout plate 53 cannot pass through, and namely achieves the blocking function that circuit breaker only can carry out closing operation after energy storage completes; Push rod 275, for removing energy storage motor, removes the driving coupling of energy storage motor and stored energy mechanism after energy storage completes.Energy storage latching member 272 pairs of energy storage control panels 271 are braked simultaneously, and now stored energy operation is no longer allowed to, thus determines the position of the energy storage completion status of circuit breaker.
When circuit breaker completes closing operation, main shaft drives the STATEMENT OF FEDERALLY SPONSORED of switching-on mechanism to rotate, and energy storage latching member 272 can be lifted reset, lock release by STATEMENT OF FEDERALLY SPONSORED after closing operation completes, and can enter the circulation of next stored energy operation.
Reserve external release interface 10 and energy storage motor interface 11 respectively on the right side of operating mechanism, two modules can be realized and install with fast simple the connecting of mechanism.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing 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.
