Description
Technical field
The utility model relates to electric power tool, specifically relates to a kind of sulfur hexafluoride breaker direct current resistance test termination.
Background technology
110kV and above electric pressure sulfur hexafluoride breaker body are higher, and during to 110kV and the test of above electric pressure sulfur hexafluoride breaker direct current resistance, the electrical test personnel need finish wiring work by high-altitude operation vehicle or 6 meters long insulating ladders.Finish wiring work meeting by high-altitude operation vehicle and produce a considerable unplanned interior recondition expense, cause unnecessary financial resources burden; Finish wiring work by 6 meters long insulating ladders, then need the electrical test personnel to climb high-rise working, especially winter outdoor cold weather, under the inflexible situation of electrical test personnel activity, sulfur hexafluoride breaker direct current resistance test jointing clamp eminence taking place in the wiring process easily drop, brings huge potential safety hazard for staircase Ziren person.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of safe, easy to operate sulfur hexafluoride breaker direct current resistance simple, that operating efficiency is high to test termination.
The purpose of this utility model realizes by following approach:
Sulfur hexafluoride breaker direct current resistance test termination, its structural feature is, include the snap close fixture, snap close movable part and insulating bar, the snap close fixture is hook construction, the one end is provided with the connecting portion of fixedlying connected with insulating bar, remainder is arc component, the snap close movable part is a spoonful shape structure, comprise spoonful body and kettleholder, the cambered surface of spoon body and the intrados of snap close fixture are to right, the two is state of siege under normal conditions, and the inboard, end of the end of spoon body and arc component touches and be subjected to the inboard restriction in this end at this moment, and the inner arc radius of arc component is greater than the length of spoon body; The junction of spoon body and kettleholder and the connecting portion of snap close fixture are hinged by jointed shaft, and the tail end of kettleholder is connected with the insulation rope; Jointed shaft is provided with the return member, and it is connected with the arc component of spoon body with the snap close fixture respectively.
Operation insulation rope, drop-down kettleholder, the spoon body is just to the interior lateral movement of arc component, because the inner arc radius of arc component is greater than the length of spoon body, therefore the end of spoon body is just away from the medial surface of arc component of snap close fixture, thereby form an opening, for the sulfur hexafluoride breaker drainage thread being put into the space that snap close fixture and snap close movable part surround.Unclamp insulation operation rope, under the effect of return member, the end of spoon body just is returned to the free end inboard of snap close fixture, has sealed and has surrounded the space, finishes remote sulfur hexafluoride breaker direct current resistance test wiring work by insulating bar then.
The utility model can be realized the wiring work of electrical test personal security, convenience, the high efficiency 110kV of finishing and the test of above electric pressure sulfur hexafluoride breaker direct current resistance, need not electrical test personnel high-rise working, prevent that effectively sulfur hexafluoride breaker direct current resistance test jointing clamp eminence from coming off, improve work on the spot efficient, guarantee personal safety.
The utility model can further be specially:
The free end of insulating bar is equipped with the insulation gum cover.
This insulation gum cover is installed in the portion of the handle of insulating bar, can be anti-skidding, and as lever.
In sum, the utility model has adopted the wiring work of remote realization electrical test personal security, convenience, the high efficiency 110kV of finishing and the test of above electric pressure sulfur hexafluoride breaker direct current resistance, need not electrical test personnel high-rise working, prevent that effectively sulfur hexafluoride breaker direct current resistance test jointing clamp eminence from coming off, improve work on the spot efficient, guarantee personal safety.
Description of drawings
Fig. 1 is the structural representation of sulfur hexafluoride breaker direct current resistance test termination of the present utility model.
Embodiment
Be described in more detail below in conjunction with the utility model of embodiment.
Most preferred embodiment 1:
Sulfur hexafluoride breaker direct current resistance test termination, include snap close fixture 1, snap close movable part and insulating bar 7, snap close fixture 1 is hook construction, the one end is provided with the connecting portion of fixedlying connected with insulating bar 7, remainder is arc component, the snap close movable part is a spoonful shape structure, comprise spoonful body 2 and kettleholder 4, the cambered surface of spoon body 2 and the intrados of snap close fixture 1 are to right, the two is state of siege under normal conditions, the inboard, end of the end of spoon body 2 and arc component touches and is subjected to the inboard restriction in this end and can not deviate from snap close fixture 1 at this moment, and the inner arc radius of arc component is greater than the length of spoon body 2; The junction of spoon body 2 and kettleholder 4 and the connecting portion of snap close fixture 1 are hinged by jointed shaft 3, and the tail end of kettleholder 4 is connected with insulation rope 5; Jointed shaft 3 is provided with retracing spring as return member 6, and it is connected with the arc component of spoon body 2 with snap close fixture 1 respectively.The free end of insulating bar 7 is equipped with insulation gum cover 8.
Drive 2 swings of spoon body by kettleholder 4, kettleholder 4 is identical with the rotation direction of spoon body 2, and return member 6 one ends are fixed on snap close fixture 1 inwall, and the other end is fixed on the inwall of spoonful body 2, under 6 effects of return member, snap close movable part and snap close fixture 1 are in impaction state during normality.Operation insulation rope, drop-down kettleholder, the spoon body is just to the interior lateral movement of arc component, because the inner arc radius of arc component is greater than the length of spoon body, therefore the end of spoon body is just away from the medial surface of arc component of snap close fixture, thereby form an opening, for the sulfur hexafluoride breaker drainage thread being put into the space that snap close fixture and snap close movable part surround.
It is same as the prior art that present embodiment is not stated part.
