Abstract
The utility model discloses a short connection testing line which comprises four leads with insulation skin, wherein one end of each of the four leads is welded with a line clip with an insulation handle, and the other ends of the four leads are welded together. The short connection testing line provided by the utility model is simple in structure and is convenient to use; the wire clips with the insulation handles are in good contact with electrical equipment, the problem of oxidation layer is solved; the leads are fixedly welded together, which can prevent the unstable data phenomenon caused by burrs of a flexible connection line and climate factors; and one of the four leads with the insulation skin can be used for grounding, which is simple and convenient.
Description
Technical field
The utility model belongs to the High-Voltage Experimentation Technology field, especially relates to a kind of short circuit p-wire.
Background technology
The insulation project of measuring electrical equipment is its state of insulation of inspection, judges the simplest householder method that it could drop into or continue to move, the voltage that is applied on the insulation project of electrical equipment and the electrical equipment and passed through current related.But often owing to environment, equipment, individual factor etc., the insulation project receives very big influence when measuring the insulation project.The insulation project of electrical equipment mainly comprises: insulation resistance, direct current leakage electric current, industrial frequency AC is withstand voltage, the measurement of dielectric loss etc.; In the process of these projects of measurement; There is burr in shorting stub owing to use in the time of to the electrical equipment short circuit; Short circuit is insecure, receives easily that there are oxide layer in weather effect or equipment surface and problem such as short circuit is unreliable, thereby makes measurement data inaccurate.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of short circuit p-wire simple in structure, easy to use.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of short circuit p-wire, it comprises four leads that have insulated hull, four lead one ends all be welded with one have an insulated handle wire clamp, the other end welds together.
Described short circuit p-wire, the pad outer cover of its four leads is provided with insulation sleeve.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This short circuit p-wire, it is simple in structure, and is easy to use, and the wire clamp that has insulated handle can be good with the electrical equipment contact, solved the problem of oxide layer; Lead firmly welds together can be avoided because of line burr and the data wild effect that climate reasons caused of being flexible coupling; Electrical equipment all is that 3 phase short circuits are measured, can reserve in the lead that therefore four have an insulated hull one earthy, simple and convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-wire clamp; The 2-insulated handle; 3-has the lead of insulated hull; The 4-insulation sleeve.
Embodiment
Below through embodiment and combine accompanying drawing that the utility model is done further explain.
As shown in Figure 1, this short circuit p-wire, it comprise four 3, four lead one ends of lead that have an insulated hull all be welded with one have an insulated handle 2 wire clamp 1, the other end welds together, the pad outer cover is provided with insulation sleeve 4.
