Intelligent automatic overload alarm type high-reliability direct-current charging pile cable

Abstract

The invention discloses an intelligent automatic overload alarm type high-reliability direct-current charging pile cable which comprises an outer protective layer, a main power supply wire core and adetector, an inner protective layer is arranged in the inner side of the outer protective layer, an outer shielding layer is arranged between the outer protective layer and the inner protective layer,the space between the outer shielding layer and the outer protective layer is filled with filling powder, a non-woven fabric layer is connected to the inner side of the inner protective layer, and reflective stripes are arranged on the outer side face of the outer protective layer. The intelligent automatic overload alarm type high-reliability direct-current charging pile cable can automaticallymonitor the use state of the cable, guarantee monitoring of the temperature of the cable, automatically give an alarm or cut off a power supply when the temperature of the cable is abnormal, guaranteesafety and avoid accident risks; and meanwhile, fire extinguishing can be conducted during melting, insects can be expelled, gnawing is avoided, it can be easily found at night, operation and use areconvenient, and long-term stable use can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of charging pile cables, in particular to a high-reliability DC charging pile cable of intelligent automatic overload alarm type. Background technique [0002] Electric vehicles are powered by on-board power supplies, and their impact on environmental pollution is greatly reduced compared to traditional vehicles. With the increasing use of electric energy vehicles, there are more and more charging piles. , The cable performance of the charging pile directly affects the service life and charging efficiency of the charging pile. [0003] The current DC charging pile cables cannot automatically monitor the current transmission during use. When the current is too high, the temperature of the cable will be too high, and even spontaneous combustion may occur, which is prone to danger. At the same time, most of the current charging pile cables, It is not convenient for automatic fire extinguishing, and at the same...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a smart and automatic overload alarm type high-reliability DC charging pile cable to solve the problem that the current DC charging pile cable proposed by the above-mentioned background technology cannot automatically monitor the current transmission during use. When it is too large, the temperature of the cable will be too high, and even spontaneous combustion will occur, which is prone to danger. At the same time, most charging pile cables are not convenient for automatic fire extinguishing. The cable is not easy to be found and taken directly at night, which is prone to unexpected problems
