Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker hand-operated tools, refers in particular to a kind of vacuum circuit-breaker manual operation specific purpose tool.
Background technology
At present, 10kV indoor vacuum circuit breaker is all configuration spring operating mechanism substantially, in design, realize the breaking-closing operating to circuit breaker with a distant place by the divide-shut brake coil on secondary low-voltage control loop controlling organization, also can be at the divide-shut brake of realizing on the spot circuit breaker by the mechanical divide-shut brake button on operating breaker operating mechanism.
In actual moving process, can there is due to a variety of causes the situation of broken string in the secondary control loop of circuit breaker, when this happens, power department is for site operation personnel's personal safety, be all often that whole section of bus in transformer station stopped, then will the circuit breaker pull-out switch cubicle of secondary control loop broken string occur, then carry out troubleshooting, why like this, to be because circuit breaker is can not carry out remote operation while breaking because of control loop time; If manually circuit breaker is operated, should open the middle cabinet door of switch cubicle, if be now that circuit breaker insulation itself has fault, the fault electric arc producing while manually operation can be gone out middle cabinet, operating personnel are damaged, and this is also that power department will have a power failure whole section of bus, processes the reason of breaker control circuit disconnection fault, this processing mode expands power failure range, and operations staff's operational ton is bigger than normal.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of vacuum circuit-breaker manual operation specific purpose tool, realizes remote manual operation circuit breaker on the spot, has improved the operating efficiency of handling failure.
The utility model is achieved in that a kind of vacuum circuit-breaker manual operation specific purpose tool, comprise hook stick, rotary contact, click contact, a plurality of intercell connectors, a plurality of fixtures, knob and snap ring, one end of described hook stick is connected to one end of described rotary contact or one end of described click contact, the other end of described rotary contact is equipped with a groove, described snap ring is socketed on hook stick, one end of described intercell connector is connected to snap ring, the other end is connected to described fixture, described fixture and described intercell connector connect one to one, described knob is connected to described snap ring.
Further, be equipped with a screwed hole on described snap ring, described knob is connected to described snap ring by described screwed hole.
Further, described hook stick is extension stem.
Further, described intercell connector is tightrope.
Further, described fixture is bolt, and this bolt is fixed on described hook stick on circuit breaker.
Further, described rotary contact is connected with being connected to of described hook stick is detachable.
Further, described click contact is connected with being connected to of described hook stick is detachable.
The utility model has the advantage of: operating personnel are by the utility model instrument, can be at the local operation to the charged stoppage circuit breaker in two ends from stoppage circuit breaker safe distance position, reduce to whole section of bus has a power failure operate workload, also saved the time of handling failure, improved the operating efficiency of handling failure simultaneously.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the structural representation that the utility model connects rotary contact.
Fig. 2 is that the utility model connects the structural representation of clicking contact.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, a kind of vacuum circuit-breaker manual operation specific purpose tool, comprise hook stick 3, rotary contact 1, click contact 2, a plurality of intercell connectors 6, a plurality of fixtures 5, knob (not shown) and snap ring 4, one end of described hook stick 3 is connected to one end of described rotary contact 1 or one end of described click contact 2, the other end of described rotary contact 1 is equipped with a groove 11, described snap ring 4 is socketed on hook stick 3, one end of described intercell connector 6 is connected to snap ring 4, the other end is connected to described fixture 5, described fixture 5 connects one to one with described intercell connector 6, described knob is connected to described snap ring 4.
On described snap ring 4, be equipped with a screwed hole 41, described knob is connected to described snap ring 4 by described screwed hole 41, described hook stick 3 is extension stem, described intercell connector 6 is tightrope, described fixture 5 is bolt, this bolt is fixed on described hook stick 3 on switch cabinet body frame (not shown), and described rotary contact 1 is connected with being connected to of described hook stick 3 is detachable, and described click contact 2 is connected with being connected to of described hook stick 3 is detachable.
In the time operating the circuit breaker of rotating structure, adopt rotary contact 1, by the knob of the groove of rotary contact 1 11 connecting breaker divide-shut brakes, again hook stick 3 is elongated, operating personnel, at the other end of specific purpose tool, realize sub-switching operation when up time rotates to an angle, otherwise realize closing operation;
In the time of the circuit breaker of action button type structure, adopt and click contact 2, two screws are fixed on switch cabinet body frame, elongate hook stick 3 to suitable length, adjust the position of clicking contact 2, in the time aiming at opening button, apply a power in the end of hook stick, opening button is produced to an inside power, and in the time that power reaches the required power of breaker open operation button, circuit breaker realizes separating brake; In like manner, click switch knob can be realized the closing operation of circuit breaker.
The utility model has the advantage of: operating personnel are by the utility model instrument, can be at the local operation to the charged stoppage circuit breaker in two ends from stoppage circuit breaker safe distance position, reduce to whole section of bus has a power failure operate workload, also saved the time of handling failure, improved the operating efficiency of handling failure simultaneously.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
