Cable electricity leakage detection device

Abstract

A cable electricity leakage detection device comprises a rack. A bearing table is arranged on the rack. A detection mechanism is arranged on the bearing table. The cable electricity leakage detection device is characterized in that the detection mechanism comprises a plurality of contacts, wherein the contacts are distributed on the bearing face of the bearing table, are electrically connected with one another and can move freely within a certain range; the detection mechanism is also provided with a signal source and a signal receiver, wherein the signal source is insulated from the contacts and is electrically connected with a cable to be detected, and the signal receiver is electrically connected with the contacts. The cable electricity leakage detection device is high in detection accuracy, accurate in detection result, free of damage to the surface of the cable and high in reliability.

Description

technical field [0001] The invention relates to a cable leakage detection device, which belongs to the field of cable manufacturing. Background technique [0002] The conventional cable structure is composed of a conductor located at the central core and an insulating sheath covering the conductor. The current insulating sheath is basically made of rubber or foaming material, but whether it is rubber or foaming material, the production of the cable is It is made by wrapping heated and softened rubber material or foam material on the conductor. [0003] The biggest disadvantage of the current production process is that it is impossible to accurately control the thickness of the insulating sheath during the production process. At present, it can only be roughly determined. Once the rubber or foaming raw materials contain impurities, causing mistakes in the heating and wrapping process, Then there will be loopholes in the insulating sheath of the finished cable produced. Once ...

[0003] The biggest disadvantage of the current production process is that it is impossible to accurately control the thickness of the insulating sheath during the production process. At present, it can only be roughly determined. Once the rubber or foaming raw materials contain impurities, resulting in mistakes in the heating and wrapping process, Then there will be loopholes in the insulating sheath of the finished cable produced. Once this section of cable is used normally, it will cause a decrease in transmission performance, or cause leakage, or even cause electric shock accidents. In the current production process, only visual inspection of the cable insulation Layer inspection, obviously can not achieve the accuracy of the inspection
