Photovoltaic cable aging resistance test device

Abstract

The invention discloses a photovoltaic cable aging resistance test device comprising a door body, a box body, a temperature sensor, a timing displayer, a heater and a ventilator. The left end of the box body is provided with the door body. The door body is provided with a handle, and the front surface of the box body is provided with a temperature control display screen. A heater switch and a lighting switch are arranged on the lower part of the temperature control display screen, and the timing displayer is installed on the lower part of the heater switch. The timing switch is arranged on thelower part of the displayer, and a ventilation rate adjusting knob is arranged on the lower part of the timing switch. The right side surface of the box body is provided with a ventilation pipe and apower plug. The upper surface of the internal part of the box body is provided with a lamp tube, and the right side surface of the internal part of the box body is provided with the temperature sensor and the ventilator. The box body, the temperature sensor, the timing displayer, the ventilation rate adjusting knob and the ventilator are arranged so that the economic and resource waste can be avoided to a certain extent and the problem of low practicability can be solved.

Description

technical field [0001] The invention relates to the technical field of aging detection, in particular to an aging resistance test device for photovoltaic cables. Background technique [0002] The reasons for aging include cable overload heating, sunshine (ultraviolet rays), ambient temperature change range, cable heat dissipation conditions, and exposure to atmospheric and environmental chemical substances, etc., which will cause the insulation and outer sheath of the cable to age, and the severe overload of the cable is to accelerate the cable. The most important reason for insulation aging is that there is information that the long-term overload working temperature of the cable exceeds the allowable long-term working temperature of the insulation by 10°, and the insulation service life of the cable will be reduced by half. Aging will cause short-circuit cable insulation aging, and the dielectric strength will decrease. The breakdown leads to the path of the cable, and now ...
