Abstract

The utility model relates to a feed cable with the leakage detection braid, which consists of a live-line copper core wire, a zero-line copper core wire and a ground-line copper core wire, wherein, an insulation layer is wrapped outside the live-line copper core wire, and a dense copper-wire braid is wrapped outside the live-line insulation layer; an insulation layer is wrapped outside the zero-line copper core wire, and an aluminum-foil or a tin foil is wrapped outside the zero-line insulation layer, and a thin copper wire braid is wrapped outside the aluminum foil or the tin foil; an insulation layer is coated outside the ground-line copper core wire; three bunches of stuff are arranged inside three gaps between the leakage detection braid and the ground-line insulation layer, and a pad and the most outer insulation layer are wrapped outside the three bunches of stuff. The feed cable of the utility model has the advantages that the cost is low, the property is reliable, and the leakage phenomenon in the feed cable can be fast and correctly detected.

Description

A kind of feed cable that has the detection of electrical leakage braiding

Technical field

The utility model relates to a kind of feed cable, refer to especially a kind of be widely used on the household electrical appliance such as air-conditioning, refrigerator, can fast detecting go out the feed cable that has the detection of electrical leakage braiding whether live wire in the feed cable or zero line exist leaky.

Background technology

Universal day by day along with household electrical appliance, people more and more pay attention to the safe in utilization of household electrical appliance.At present, various electrical equipment are in order operate as normal all to carry about one 1 meter or longer power line.This power line is to be made of three copper cores, be enclosed with a layer insulating (as rubber or plastics) respectively in the outside of every copper core, be enclosed with the very dense copper cash braiding of one deck again in the outside of the insulating barrier of live wire copper core and zero line copper core, at last, the outermost at three copper cores wraps up a layer insulating (as rubber or plastics) again.

In long-term use, this power line is usually because ageing of insulation or breakage, causes slight electric leakage between the live wire, zero line (neutral line), ground wire in the power line, produces spark and causes fire, and the phenomenon that causes the user to be subjected to personal property loss takes place.Whether there is leaky in order to detect power line quickly and accurately, people link to each other the copper cash braiding of braiding of the copper cash of live wire insulating barrier outside and zero line insulating barrier outside usually, weave by the detection copper cash and whether chargedly judge whether power line exists leaky.

Because it is very high to be wrapped in the copper cash percentage of braiding coverage of live wire and zero line copper core insulating barrier outside, be to weave by copper cash one by one to form very densely, constantly soaring along with the copper material price causes the cost of this power line to improve constantly.

Summary of the invention

In view of the foregoing, the purpose of this utility model provide a kind of be widely used on the household electrical appliance such as air-conditioning, refrigerator, that have detection of electrical leakage braiding, cause the low feed cable of cost.

For achieving the above object, the utility model by the following technical solutions: a kind of feed cable that has detection of electrical leakage braiding, this feed cable is made of a live wire copper core, a zero line copper core and a ground wire copper core;

The outside of described live wire copper core is coated with a layer insulating, also is coated with the braiding of one deck detection of electrical leakage in the outside of insulating barrier;

The outside of described zero line copper core is coated with a layer insulating, is coated with the layer of metal paper tinsel in the outside of insulating barrier, also is coated with the braiding of one deck detection of electrical leakage in the outside of metal forming;

The outside of described ground wire copper core is coated with a layer insulating;

Described detection of electrical leakage braiding and ground line insulating layer contact respectively, in three gaps that their outside forms the three beams filler are arranged respectively;

The outside of braiding of described three beams filler, detection of electrical leakage and ground line insulating layer is coated with one deck liner, in the coated outside of liner one deck outermost layer insulating barrier is arranged.

In specific embodiment of the utility model, the detection of electrical leakage braiding in described live wire copper core insulating barrier outside is the dense copper cash braiding of one deck, and the layer of metal paper tinsel that is coated on zero line copper core insulating barrier outside is one deck aluminium foil or tinfoil paper.The detection of electrical leakage braiding that is coated on aluminium foil or tinfoil paper outside is the sparse copper cash braiding of one deck.

Because the utility model is with in traditional power line, the live wire that is woven into by copper cash one by one and the detection of electrical leakage braiding of zero line densely, the detection of electrical leakage braiding that changes live wire into is the dense copper cash braiding of one deck, and very thin aluminium foil of one deck or tinfoil paper being set in zero line copper core insulating barrier outside, the detection of electrical leakage braiding in aluminium foil or tinfoil paper outside is the sparse copper cash braiding of one deck.Greatly reduce the cost of power line like this.

The utility model has the advantages that: cost is low, and dependable performance can detect whether have leaky, protection equipment and personal safety as well as the property safety in the feed cable quickly and accurately.
