Description
Technical field
The utility model relates to the switching-off device of circuit breaker, relates in particular to a kind of circuit breaker cart emergency brake-dividing device.
Background technology
When the service position of circuit breaker cart in switch cubicle, and switch on while entering running status, in case of emergency needs separating brake, but while can not remote control realizing, need directly quick breaking circuit breaker on the spot, the utility model relates to a kind of novel breaker handcart emergency brake-dividing device, can realize safely, easily and quickly circuit breaker cart direct separating brake on the spot in case of emergency.
Circuit breaker cart for electric pressure lower than 12kV, because the stroke from test position to service position is shorter, circuit breaker cart is in the time of service position, nearer apart from cabinet door, and the opening button that therefore can arrange on cabinet door on the moving circuit breaker cart of button immediate roof realizes emergency opening.But the circuit breaker cart of 40.5kV is because the stroke from test position to service position is longer, and this kind of mode is just infeasible.
Existing 40.5kV circuit breaker cart is only provided with emergency opening button on circuit breaker panel, in the time that chance emergency needs manually direct separating brake, need first door of switch cabinet to be opened, realize emergency opening by the button on the moving circuit breaker cart panel of the hand-held insulating bar immediate roof of operating personnel again, can not realize quick acting switching-off, incur loss through delay eliminating and processing to fault, simultaneously because cabinet door opens wide, the arcing that breaker open operation drop-out current causes can not be limited in switch cubicle, may damage operating personnel's personal safety, the grade that causes the accident rises.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of circuit breaker cart emergency brake-dividing device is provided, solve breaker open operation equipment safety in current technology low, can not realize quick acting switching-off, incur loss through delay and get rid of and the problem of handling failure.
For solving above technical problem, the technical solution of the utility model is:
A kind of circuit breaker cart emergency brake-dividing device, comprise bull stick, transmission mechanism, latch lever and separating brake push pedal, it is characterized in that, described transmission mechanism one end is connected with bull stick, the other end is connected with latch lever, separating brake push plate device is also rotatable on the support of handcart mechanism case inside, on support, be also connected with separating brake dropout plate, the casing that latch lever penetrates handcart mechanism case is driven and can be moved up and down by transmission mechanism, when latch lever moves down, promote separating brake push pedal and rotate, separating brake push pedal promotes separating brake dropout plate rotation dropout again and realizes separating brake.Emergency opening mechanism described in the utility model utilizes link gear without opening switch cabinet cabinet door in the situation that, to realize separating brake action, bull stick makes latch lever produce upper and lower displacement by transmission mechanism after rotating, thereby the push pedal of latch lever promotion separating brake makes separating brake push pedal promote separating brake dropout plate rotation dropout again and realizes separating brake, and emergency opening relies on separating brake push pedal to promote separating brake dropout plate and realizes separating brake, not to directly act on separating brake dropout plate, make emergency opening be totally independent of electronic separating brake, both are non-interference, can not cause chain function disorder.
Further, described transmission mechanism articulated mounting is on handcart mechanism case, and transmission mechanism is connected with bull stick by hinge, and the junction of transmission mechanism and latch lever is provided with chute, is fixed with in the chute that pin is set on transmission mechanism on latch lever.Rotatablely moving of bull stick drives transmission mechanism to rotate, and latch lever can upper and lower moving occur along the chute on transmission mechanism, thereby realizes the separating brake of circuit breaker by turn bull stick.
Further, on described bull stick, device has knob, the rotation dynamics of utilizing knob to reduce to apply, the separating brake of convenient and circuit breaker.
Further, be also connected with connecting lever on described latch lever, connecting lever is hinged in handcart mechanism case, drives connecting lever rotation when latch lever moves up and down, and connecting lever rotation to the combined floodgate direction of the dropout plate that closes a floodgate stops false switching.When making latch lever move downward separating brake, drive the other end of connecting lever to turn in the combined floodgate direction of combined floodgate dropout plate, can stop the dropout of moving backward of combined floodgate dropout plate, prevent from closing circuit breaker in operating breaker emergency opening process by mistake, compare that can only to realize the crosslinking lock scheme of separating brake more complete, fail safe is more secure.
Further, described connecting lever is provided with adjustable and screw combined floodgate dropout sheet separation, and adjusting play makes to prevent that false switching is more reliable.
Compared with prior art, the utility model advantage is:
Circuit breaker cart emergency brake-dividing device described in the utility model can directly be realized emergency opening under the state of closing the door, emergency opening is totally independent of electronic separating brake, both are non-interference, can not cause chain function disorder, and both realized separating brake safely and fast in emergency circumstances, prevent from again closing circuit breaker in separating brake process, crosslinking lock scheme improves reliable simultaneously by mistake; Circuit breaker cart emergency brake-dividing device described in the utility model is simple in structure, easy for installation, practical, simple to operate, safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
