Technical field
The utility model relates to preventing misoperation of high-tension switch cabinet technical field, particularly the mechanical interlocking device of a kind of novel breaker and isolating switch.
Background technology
Isolating switch has obvious cut-off point, can realize isolation features, mainly as equipment repair and maintenance, uses.But isolating switch does not have breaking function, can not on-load divide-shut brake, only under load disconnection, just can carry out isolating switch deciliter; And normal deciliter of circuit breaker energy and disjunction load are controlled use as equipment, but whether circuit breaker is without obvious cut-off point, can not disconnect in intuitive judgment loop, is not suitable as overhaul of the equipments and uses.Therefore, for reaching energy on-load disjunction loop, can make again loop there is obvious cut-off point, facilitate repair and maintenance, in high-voltage complete-set switch cabinet, must a mechanical interlocking device will be added between isolating switch and circuit breaker, to meet isolating switch, only have circuit breaker under load disconnection, just can carry out divide-shut brake, otherwise isolating switch on-load deciliter and the phenomenon of the short circuit in high-voltage complete-set switch cabinet occurs.At present, the mechanical interlocking device complex structure using, " five is anti-" poor performance, mechanical action is insensitive, very inconvenient during use.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple in structure, novel breaker that economic benefit is high, machinery is flexible, can effectively prevent on-load deciliter isolating switch, meet switch cubicle " five anti-" requires and the mechanical interlocking device of isolating switch are provided.
The purpose of this utility model is achieved through the following technical solutions: the mechanical interlocking device of a kind of novel breaker and isolating switch, it comprises fixed vacuum breaker, isolator operation bar and be arranged on the isolating switch in fixed vacuum breaker, it also comprises circuit breaker interlocking gear, isolator operation handle and connecting rod, on the inwall of described fixed vacuum breaker, be hinged with fan-shaped turntable, one end of isolator operation handle is hinged on fan-shaped turntable top, the other end of isolator operation handle is arranged on the outside of fixed vacuum breaker, connecting rod head end is hinged on fan-shaped turntable bottom, connecting rod end is hinged on isolator operation bar, described circuit breaker interlocking gear is by top board, supporting seat, drive link, screw mandrel and locking nut form, supporting seat is fixedly mounted on fixed vacuum breaker top, top board is hinged on supporting seat, on top board, be provided with slotted eye, drive link one end is hinged on the middle part of fan-shaped turntable, the drive link other end is through slotted eye, screw mandrel is threaded with locking nut respectively perpendicular to drive link setting and screw mandrel two ends, the length of screw mandrel is greater than slotted eye.
It also comprises plain cushion, and plain cushion is arranged on drive link and between locking nut and top board.
Four layers of plain cushion are installed on described drive link.
Described isolator operation handle for bow font/.
The utlity model has following advantage: circuit breaker interlocking gear of the present utility model is by top board, supporting seat, drive link, screw mandrel and locking nut form, supporting seat is fixedly mounted on fixed vacuum breaker top, top board is hinged on supporting seat, on top board, be provided with slotted eye, drive link one end is hinged on the middle part of fan-shaped turntable, the drive link other end is through slotted eye, screw mandrel is threaded with locking nut respectively perpendicular to drive link setting and screw mandrel two ends, the length of screw mandrel is greater than slotted eye, when pulling on isolator operation handle, fan-shaped turntable turns clockwise, connecting rod and isolator operation bar rotate with fan-shaped turntable, isolating switch is in closing position, fixed vacuum breaker energy storage, prevented that on-load from closing isolating switch, thereby realized the operation of safe power transmission, when leaving behind isolator operation handle, fan-shaped turntable is rotated counterclockwise, connecting rod and isolator operation bar rotate with fan-shaped turntable, isolating switch is in open position, fixed vacuum breaker can not close a floodgate, only have when artificial isolating switch after fixed vacuum breaker separating brake is just separated immediately, prevented that on-load from dividing isolating switch, have simple in structure, mechanical action is flexible, meet the feature that switch cubicle " five is anti-" requires.
