Abstract

The invention relates to a solar heat dissipation device of a low-voltage electric power metering box and a use method of the solar heat dissipation device, and belongs to the technical field of heatdissipation of 0.4KV power supply facilities. According to the technical scheme, two solar panels (1) are mounted at the upper part of the metering box in parallel; an air supply direct-current motor(13) is mounted at the upper part of the left side of a box body of the metering box; an air draft direct-current motor (14) is mounted at the lower part of the right side of the box body of the metering box; the air supply direct-current motor (13) and the air draft direct-current motor (14) are connected with an air supply fan and an air draft fan respectively; the output ends of the solar panels (1) are connected with a lithium battery (7) through a voltage stabilizing chip (7); the output end of the lithium battery is connected with the air supply direct-current motor and the air draft direct-current motor through a temperature control switch (9); and the air supply direct-current motor and the air draft direct-current motor are connected in parallel. The device has the beneficial effects that solar power is used for generating power; the fans are driven to dissipate heat through the rotation of the direct-current motors; air in the box is subjected to convection, so that the purposes of reducing the temperature and the humidity in the box are achieved; and the energy is saved and the efficiency is high.

Description

technical field [0001] The invention relates to a solar heat dissipation device for a low-voltage power metering box and a use method thereof, and belongs to the technical field of heat dissipation equipment for 0.4 kilovolt power supply facilities. Background technique [0002] The low-voltage power metering box is an effective carrier for the reasonable distribution of electric energy by the metering device in the low-voltage power supply line. According to the QGDW11008-2013 "Technical Specifications for Low-Voltage Metering Boxes", the metering box has certain requirements for the temperature and humidity of the working environment. The upper limit of the air temperature should not exceed 60°C, the lower limit should not be lower than -25°C, and the humidity should not be higher than 75%. However, for metering boxes installed outdoors or in temporary buildings, especially in summer, not only the ambient temperature is very high, but also the operation of the metering dev...
