Technical Field

[0001] The utility model belongs to the field of high-voltage electricity detection and relates to an insulation measurement auxiliary device for a high-voltage switch cabinet. Background Art

[0002] When performing insulation testing on the wiring inside the front cabinet of a high-voltage switchgear, engineers need to enter the cabinet to connect the test leads. The narrow interior space of some high-voltage switchgear makes entry and exit difficult, and there is also a risk of electric shock.

[0003] Until now, engineers have used makeshift tools outside the high-voltage switchgear to connect the measuring wires to the connectors inside the switchgear. Although this can prevent people from entering the switchgear, there is still a risk of the measuring wires falling off or connecting with other facilities and connectors in the high-voltage switchgear, leading to short circuits. Utility Model Content

[0004] In order to overcome the defects in the above-mentioned related technologies, the utility model provides an insulation measurement auxiliary device for a high-voltage switchgear, which has the advantages of being easy to operate, safe and reliable.

[0005] To address the above-mentioned technical problems, the present invention provides an auxiliary insulation measurement device for high-voltage switchgear. The auxiliary insulation measurement device comprises a measuring terminal, an insulating rod, and a measuring wire. The measuring terminal comprises a conductive member. The insulating rod is a rod having the measuring terminal fixed to one end. One end of the measuring wire is fixedly connected to the measuring terminal and is fixedly positioned along the insulating rod. A terminal is provided at the other end of the measuring wire.

The fixing sleeve is screwed onto one end of the insulating rod through the first threaded hole. The plug-in rod is a threaded rod, with a conductive member fixed to one end of the plug-in rod and secured within the second threaded hole.

[0009] Preferably, the fixing sleeve is an insulating member, the first threaded hole and the second threaded hole are connected, and the measuring wire extends from the insulating rod into the fixing sleeve and is fixedly connected to the conductive member.

[0010] Preferably, the fixing sleeve is provided with a wire through-hole, the wire through-hole communicating with the connection point between the first and second threaded holes, and the measuring wire extends from the wire through-hole to the outside of the fixing sleeve.

[0011] Preferably, the conductive member is a copper rod.

[0012] Preferably, a handle is provided at the other end of the insulating rod.

[0013] The beneficial effects of the present invention are:

[0014] First, the utility model can conveniently and quickly assist engineers in electrically connecting the L-line terminal of the insulation tester to the terminal to be tested of the high-voltage switch cabinet.
