Take electricity verification function's ground wire couple

Technical Field

The invention relates to the technical field of electric power safety, in particular to a ground wire hook with an electricity checking function.

Background

The grounding wire is commonly used for the low-voltage side of a desk type transformer in a 380/220V power distribution network, and four-phase contacts on the low-voltage side A, B, C, N of the transformer are grounded, so that the safety of the transformer or a rear-section line and workers in overhaul is protected.

However, in a bench transformer working site, after a worker climbs a pole to a proper position to start grounding a low-voltage side of the transformer, according to the requirements of safety working regulations, the low-voltage electroscope needs to be carried by the electroscope before grounding, the electroscope is large in size and inconvenient to carry and use, the grounding lead of the low-voltage grounding wire is not allowed to touch the body of the person, so that a plurality of insulating poles can be held by one hand, the lead end clamping heads are mounted to the low-voltage side of the transformer phase by the other hand, the grounding wire is not placed, the grounding working efficiency is low, time and labor are consumed, safety risks are generated, and meanwhile, the lead end clamping heads mounted by one hand can be unstable and cause safety risks. In view of this problem, it is desirable to invent a low-voltage ground wire hanger on which the low-voltage ground wire is temporarily hung, i.e., a wire-end clip can be installed phase by phase using both hands. In addition, in consideration of the electricity testing link of the transformer before grounding, in order to avoid carrying the electroscope repeatedly, the electricity testing function is implanted into the hook.

Disclosure of Invention

The technical scheme of the invention is that; the utility model provides a take low pressure earth connection couple of electricity test function, includes the couple body, the couple body is double-end bending structure, the one end of couple body is equipped with the metal tip, and the other end of couple body is equipped with the neon tube, be equipped with the metal cap on the neon tube, couple body is equipped with metal tip one side and hangs on the channel-section steel of desk-top transformer bottom, and the opposite side is used for hanging low pressure earth connection wire end chuck.

Further, the inside of the hook body is made of hard metal, and the outer surface layer is wrapped with the anti-skid insulating leather. The inside of the hook body is made of hard metal, so that the hook body has a supporting effect and a conductive effect, and the metal appearance is made of insulating leather with a large friction coefficient, so that the hook body has an electric shock preventing effect and an anti-skidding effect.

Further, the double-end bending structure comprises a first clamping groove and a second clamping groove, the opening directions of the first clamping groove and the second clamping groove are opposite, the metal tip is arranged on one side of the first clamping groove, the other side of the first clamping groove is connected with one side of the second clamping groove in parallel, and the neon tube is arranged on the other side of the second clamping groove.

Further, the first clamping groove is clamped on the channel steel at the bottom of the desk type transformer, the metal tip touches the low-voltage side of the transformer, and the second clamping groove is used for hanging a low-voltage ground wire lead end clamping head.

The head part of the hook is of a pointed metal structure and is used for touching the low-voltage side of the transformer; the tail part is a neon tube and a metal cap, and the neon tube shines when current passes through, which indicates that the conductor is electrified.

And (3) performing electricity inspection: the second clamping groove is held by the hand, the finger contacts the metal cap, the metal tip contacts the low-voltage side of the transformer, and the conductor electrified neon tube is lightened, and the non-electrified neon tube is not lightened.

And (3) hooking: the first clamping groove of the hook body is hung on the channel steel at the bottom of the transformer, after the hook body is fixed firmly, the clamping heads of the wire ends of the low-voltage grounding wires are hooked on the second clamping groove of the hook body, and then the clamping heads of the wire ends of the grounding wires are taken out from the second clamping groove phase by phase to ground each phase of the low-voltage side of the transformer.

The invention has the beneficial effects that;

(1) The volume is small, and the carrying is convenient;

(2) The multifunctional electric power meter has the functions of a hook and an electricity inspection;

(3) The structure is reasonable, the low-voltage grounding wire can be hung, and the working efficiency is improved.
