Abstract
The utility model relates to high-voltage direct current resistance testing pliers with an induction electrical alarm, belonging to a special tool for detecting the wiring of high-voltage switch equipment of an electrical power system. A pliers opening (3) is manufactured into a sawteeth shape, is provided with a chunk blocking device (6) and can meet the wiring requirements of different angles; and the top part of the pliers is provided with an induction electrical alarm (2). The high-voltage direct current resistance testing pliers is especially suitable for being applied to the electrical power system, can ensure the safety of testing personnel, avoid the testing personnel from entering electrified intervals for work by mistake and further avoid personal injury and fatal accidents.
Description
Technical field
The utility model relates to a kind of high voltage direct current resistance testing clamp with the induced electricity warning device, belongs to the wiring specific purpose tool that detects the electric system high-tension switch gear.
Background technology
General known high voltage direct current resistance testing clamp, clamping, to overcome the oxide film effect limited, is difficult to fixingly when being used for different angles testee wiring position, and do not avoid the preventive measure of mistakenly entering charged chamber.
The utility model content
In order to clamp testee better, improve the effect that overcomes oxide film, high voltage direct current resistance testing clamp bit is made into serrate.High voltage direct current resistance testing clamp chuck angle can change between 0～90 degree, be to have utilized a hinge to be connected on the chuck with chuck bracket leg support, but be difficult to fixing during practical application, make troubles to work, the utility model increases the chuck blocking device, so just has been suitable for the needs of different angles testee wiring position, and is indeformable during warranty test, do not replace, can be handling, practicality is stronger.
Existing aerological measurement instrument does not have the induced electricity warning device, and it is not enough to the testing clamp distance that overtesting personnel's mistakenly entering charged chamber work or charging equipment take place in the work, led to human casualty accident.This testing clamp application combination principle increases the non-contact type high voltage warning device at the top, be particularly suitable for electric system and use, and has guaranteed the safety of testing crew.The utility model is when charging equipment is not enough to the testing clamp distance, and the induced electricity warning device will be reported to the police, and therefore can effectively avoid the generation of pernicious human casualty accident.
The technical scheme that its technical matters that solves the utility model adopts is: high voltage direct current resistance testing clamp bit is made into serrate, so can effectively overcome the oxide film of caught object, contacts well with caught object.High voltage direct current resistance testing clamp increases the chuck blocking device, selects locking after the suitable angle, so just has been suitable for the needs of different angles testee wiring position, and is indeformable during warranty test, do not replace, can be handling, practicality is stronger.This testing clamp increases non-contact type high voltage induced electricity warning device at the top, load onto bolt in non-contact type high voltage induced electricity warning device bottom, the installing nut connects at high voltage direct current resistance testing clamp top, is particularly suitable for electric system and uses, and has guaranteed the safety of testing crew.
The beneficial effects of the utility model are: band induced electricity warning high voltage direct current resistance testing clamp, and the design of jaw shape, clamp is oxide film dissolving simultaneously; And blocking device is housed, can adapts to the wiring demand of different angles, improved the work efficiency of test.Novelly be provided with the induced electricity warning device, be particularly suitable for electric system and use, safety that can the warranty test personnel at its top.Stop the work of testing crew mistakenly entering charged chamber, or charging equipment is not enough to the testing clamp distance, has led to the personal injury serious accident
Description of drawings
Fig. 1 is band induced electricity warning high voltage direct current resistance testing clamp.
Fig. 2 is a non-contact type high voltage induced electricity warning device.
Fig. 3 is a high voltage direct current resistance testing clamp.
Fig. 4 is band induced electricity warning high voltage direct current resistance testing clamp chuck locking principle figure.
Among the figure 1, non-contact type high voltage induced electricity warning device; 2, high voltage direct current resistance testing clamp; 3, the jaw of testing clamp; 4, nut; 5, bolt; 6, blocking device.
Embodiment
When testing crew adopted the high-altitude testing clamp to carry out test such as switch contact resistance, operating type was as follows:
When testing crew need carry out the test of different angles, utilize blocking device, the problem that has been difficult to fix in the time of both can having solved test different angles testee wiring position.
Band induced electricity warning high voltage direct current resistance testing clamp is equipped with the induced electricity warning device at the top, safety that can the warranty test personnel, prevent testing crew mistakenly entering charged chamber work in the work, or charging equipment is not enough to the testing clamp distance, has led to human casualty accident.The utility model is when charging equipment is not enough to the testing clamp distance, and the induced electricity warning device will be reported to the police, and therefore can effectively avoid the generation of pernicious personal injury.
