The high voltage circuit breaker cart brake separating mechanism has simple structure and low manufacture cost, and is applicable to high voltage switch cabinet cart reconstruction.
Description
Technical field
The utility model relates to the High voltage power supply equipment field, specifically a kind of circuit breaker cart brake separating mechanism.
Background technology
At present, the transformation of oil-minimum breaker handcart remains one of main production task of numerous switchgear planies, circuit breaker cart must be to be in gate-dividing state before advancing the high-voltage board closing position, if when breaker closing, just handcart is advanced in the handcart cabinet, if the precautionary measures that there is no need, certainly will cause serious accident, institute is so that circuit breaker cart just can make the reliable separating brake of circuit breaker before shifting handcart cabinet closing position onto, be that old-fashioned handcart is carried out the major issue that vacuum is transformed, in separating brake mode in the past, all be the hard connection of brake separating mechanism mostly, this separating brake mode only is applicable to handcart brake separating mechanism and the near handcart of breaker open operation mechanism distance, but also being subjected to the restriction of the direction of motion, its connector is made complicated, difficulty is installed, production cost is higher.
Summary of the invention
The utility model overcomes disadvantages of background technology, and a kind of novel high-voltage circuit-breaker cart brake separating mechanism is provided, and that this brake separating mechanism connector is made is simple, install easily, production cost is low.
The design that its technical problem that solves the utility model adopts is: the foot-operated tripping mechanism of former handcart was improved with being connected of breaker open operation mechanism.That is: in the breaker open operation transmission mechanism component, adopted a bicycle brake line, one end of the steel wire brake cable at brake cable center is linked to each other with separating brake flap in the breaker open operation mechanism, the foot-operated tripping mechanism of the other end and handcart movable part---the lower limit bar links to each other, and the two ends of brake cable crust are individually fixed in the breaker open operation flap, ride the correct position of tripping mechanism annex by the brake cable fixture; Like this, as long as step the handcart pedal, it can drive brake cable motion, the brake cable motion pulling breaker open operation flap realization separating brake that rotates.
The beneficial effects of the utility model:
1, simple in structure, reliability is high
Circuit breaker cart brake separating mechanism in the past is formed by connecting by machined piece mostly, and parts are many, and turning joint is more, causes idle stroke big, if service time is long, makes that the gap becomes big between the parts, reliably separating brake.The utility model couples together brake separating mechanism and breaker open operation plate by bicycle brake line, and parts are few, does not have the idle stroke problem, and reliability improves greatly.
2, production cost is low
The utility model has adopted the bicycle brake line to connect, it self low price, and 2 yuan/bar only, the versatility of element and standardization level improve, and need the element of processing to reduce, and have reduced processing cost and have shortened the production cycle.
3, applied range
Be not subjected to the separating brake position of primary cut-out and the influence of separating brake angle, in any position, different angles can both realize reliable separating brake, and are suitable equally in different handcarts.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Transmission mechanism of the present utility model has utilized bicycle brake line (22), its structure outermost one deck black PVC shell, the inside one deck is a screw-type spring-like iron pipe, the inside is a pipe in the white PVC again, the center is the steel wire brake cable, at first to process two (amount) brake cable fixtures (23) (metalwork), zinc-plated processing after the processing, after finishing, a brake cable fixture (23) is installed near the high pressure cart frame (1) of breaker open operation plate (3) goes up (as Fig. 3), brake cable fixture (23) is fixed with a screw, its adjustable angle, adjust the angle of brake cable fixture (23), the center line that as far as possible makes separating brake point and brake cable fixture centre bore is tightened fixed screw point-blank; Brake cable is extracted out from the black brake string set, one with the black brake string set is installed in brake cable fixture the inside and firm with the jackscrew top, the steel wire brake cable is passed to the metal backup of the brake cable end from the aperture of the separating brake flap (3) of circuit breaker, brake cable is pierced into brake string set from the aperture of brake cable fixture (23), also use brake cable fixture (23) to be fixed on foot-operated brake separating mechanism neighbouring (as Fig. 2) other end of brake string set, bore the brake cable hole of a Φ 2 at separating brake push rod (6) correct position, residue is exposed at the outer brake cable of brake string set to pass from this hole, the tension brake cable is fixed with brake cable screw (21); With circuit breaker (2) closing by hand, with the foot-operated brake separating mechanism of handcart circuit breaker (2) is tested separating brake, regulate the length of brake cable, make reliably separating brake of circuit breaker, after the handcart brake separating mechanism resetted, breaker open operation plate (3) can reliable reset.
If under primary cut-out (2) "on" position, circuit breaker cart is sent in the high-voltage board, in sending into process, the inclined-plane of high-voltage board bottom limit body can be with separating brake push rod (6) jack-up, the motion pulling steel wire brake cable of separating brake push rod (6), and the steel wire brake cable spurs the breaker open operation flap and impel primary cut-out (2) separating brake before arriving test position; When circuit breaker cart was in "on" position in high-voltage board, running into emergency can drive handcart separating brake push rod (6) by pedal (4) and move upward with foot-operated pedal (4) down, realizes the action request (course of action is the same) of separating brake.When handcart was in test or service position, separating brake push rod (6) can be kept in the center under the effect of pedal back-moving spring (5), can normally close, divide operation to primary cut-out (2).
