Abstract
The utility model relates to the technical field of a vacuum breaker, in particular to a switching-on controlling mechanism of a breaker, having a program lock, a connecting bar, a crank and a locking lever, a fixed plate with the program lock is fixed on the top end of a cabinet, a guide plate A and a guide plate B are fixed on the top and bottom of the inner wall of the cabinet, the connecting bar is connected with the program lock and penetrates through the guide plate A, a stop screw and an adjusting screw are arranged on the connecting bar, the adjusting screw is used for adjusting the gap between the connecting bar and a switching-on semi-axis push button plate, the stop screw extends to a plastic disk at the locking lever end, the locking lever penetrates through the guide plate B and is connected with the crank by a pin, the other end of the crank is connected with a main shaft which is fixed in a mounting hole of the cabinet. By adopting the switching-on controlling mechanism, when the program lock is in the deblocking state, the breaker can normally switch on and off, when the breaker is in the switching-on state the key of the program lock is unable to be drawn out, thus preventing the incorrect manipulation, greatly improving the use safety program of the breaker and having compact appearance.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker technical field, especially a kind of combined floodgate controlling organization of formal dress formula circuit breaker.
Background technology
The electric misoperation of high-voltage switch gear causes accidents such as power equipment damage, system blackout even casualties easily.Existing interlocking realize with regard to require machinery and electric aspect require all to realize that the scheme of interlocking has a lot, function also can meet the demands, but some part is more, need be arranged into outside the cabinet, influence its outward appearance, therefore we adopt a kind of novel interlocking, and most of part is integrated into the circuit breaker cabinet inside, make its function and outward appearance that bigger improvement all be arranged.This interlocking method generally as the supplementary means of mechanical interlocking, is realized dual interlock.The interlocking that solves two cabinets can adopt procedure lock to satisfy anti-error function.
The utility model content
The technical problems to be solved in the utility model is: the safe coefficient of combined floodgate controlling organization that solves original formal dress formula circuit breaker is low, the technical problem of misoperation easily takes place.The utility model provides a kind of combined floodgate controlling organization of formal dress formula circuit breaker, stops misoperation, improves fail safe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of combined floodgate controlling organization of formal dress formula circuit breaker has procedure lock, connecting rod, connecting lever, blocking lever, the fixed head that procedure lock is housed is fixed on enclosure top, and the cabinet inwall is fixed with guide plate A up and down, guide plate B, connecting rod links to each other with procedure lock, passes guide plate A, and stop screw and adjustment screw are installed on the connecting rod, adjustment screw is positioned at the rear of combined floodgate semiaxis button panel, is used to regulate and the gap between the semiaxis button panel of closing a floodgate; Stop screw length extends on the plastics disk of interlocking rod end, and blocking lever passes guide plate B, links to each other with connecting lever one end by pin, and the connecting lever other end links to each other with main shaft, and main shaft is fixed in the cabinet installing hole.
When circuit breaker is in "on" position, the procedure lock key can not be extracted, at this moment, connecting rod is in the state of being raised, the connecting rod lower end exceeds the top of combined floodgate semiaxis button panel, and the combined floodgate semiaxis rotates unrestricted, and circuit breaker normally closes a floodgate, drive connecting lever and rotate to closing position, blocking lever is lifted, and the plastics disk has blocked stop screw, and connecting rod can't be moved downward, therefore procedure lock can not lock, and key can't be pulled out.
Behind breaker open operation, connecting lever is rotated counterclockwise, and connecting rod is removed spacing, moves downward, and procedure lock promptly locks, and key can be extracted.
The beneficial effects of the utility model are: adopt the utility model combined floodgate controlling organization, when procedure lock is in released state, circuit breaker can the normal occlusion separating brake; When circuit breaker self was in "on" position, the procedure lock key can not be extracted, and prevented the generation of misoperation from root, improved the program safe in utilization of circuit breaker greatly, and outward appearance was succinct.
