Abstract
The utility model relates to the technical field of a vacuum circuit breaker, particularly to a switch-on/off control mechanism of a side-mounting circuit breaker. The control mechanism comprises an interlocking plate of a switch-on half shaft, a program lock, a revolving shaft and a spindle turning arm, wherein the program lock provided with a small turning arm is fixed outside a case; the interlocking plate of the switch-on half shaft is connected with the switch-on half shaft; a limit plate, a plate and a straight plate are fixed in a clamping groove of the revolving shaft through bolts; the revolving shaft is mounted in a fixing hole of the case; one end of a tension spring is connected with the straight plate and the other section of the tension spring is fixed on the bolts of the case; and meanwhile, the straight plate and the spindle turning arm are interlocked and matched. The control mechanism with simple and attractive appearance has the benefits that the switch-on section directly controlling the circuit breaker can not perform the switch-on operation, thereby radically eliminating dangers; and the switch-on operation cannot be conducted and the energy cannot be repeatedly stored, so that the misoperation is prevented and the service life of the mechanism is prolonged.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker technical field, especially a kind of on/off switch controlling organization of side dress 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 on/off switch controlling organization that solves original side dress circuit breaker is low, easily produce misoperation, short technical problem of mechanism's life-span.The utility model provides a kind of on/off switch controlling organization of side dress vacuum circuit-breaker, improves fail safe, prevents misoperation, prolongs mechanism's life-span.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of on/off switch controlling organization of side dress circuit breaker, has combined floodgate semiaxis interlock plate, procedure lock, rotating shaft, the main shaft connecting lever, the procedure lock that little connecting lever is housed is fixed on outside the cabinet, combined floodgate semiaxis interlock plate is connecting the combined floodgate semiaxis, with screw limiting plate, plate, straight plate are fixed in the draw-in groove of rotating shaft, rotating shaft is installed in the cabinet fixing hole, extension spring one end is connected with straight plate, and another section is fixed on the cabinet screw, and simultaneously straight plate forms an interlocking matching relationship with the main shaft connecting lever under the extension spring effect.
Described rotating shaft is provided with draw-in groove, and in the draw-in groove of rotating shaft, limiting plate and straight plate are in rotating shaft the same side by screw for limiting plate, plate, straight plate, and plate is at opposite side, and three blocks of plates are at same horizontal plane.
Described main shaft connecting lever one end is provided with a spacing bending.
Procedure lock control normal operation of circuit breaker, during "on" position, the main shaft connecting lever blocks straight plate, and rotating shaft can't be turned clockwise, and plate is forced to perk, causes little connecting lever can't rotate to the upright position, so the procedure lock key can not be rotated in place, can't extract.At this moment, procedure lock is in open mode, and circuit breaker can the normal occlusion separating brake, and self is in "on" position circuit breaker.
Behind breaker open operation, the main shaft connecting lever moves counterclockwise, and straight plate breaks away from its snap close, the procedure lock key is promptly rotatable, drive little connecting lever and rotate to assigned address, depress plate drives the rotating shaft rotation, simultaneously, limiting plate is rotated in place, and an end withstands the lower end of combined floodgate semiaxis interlock plate, and combined floodgate semiaxis interlock plate can't be rotated counterclockwise, thereby stop the rotation of combined floodgate semiaxis, circuit breaker can't be closed a floodgate.
The beneficial effects of the utility model are: one, directly control the combined floodgate part of circuit breaker, can not carry out closing operation, fundamentally stopped dangerous existence; Two, can not carry out closing operation, also can not repeat energy storage, prevent misoperation, thereby increase the useful life of mechanism; Three, outward appearance is succinctly attractive in appearance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model procedure lock is opened, the circuit breaker view of normally closing a floodgate;
