Solar electrical cabinet with automatic temperature adjusting function

Abstract

The invention discloses a solar electrical cabinet with the automatic temperature adjusting function. The solar electrical cabinet comprises an electrical cabinet body, a solar power supply system installed at the top of the electrical cabinet body and a temperature control system installed on the upper portion of the electrical cabinet body. The interior of the electrical cabinet body is internally provided with foaming agents, an interlayer is arranged outside the electrical cabinet body, and the foaming agents and the interlayer have the heat insulation and heat preservation effects on the interior of the electrical cabinet body. The solar power supply system comprises a solar crystalline silicon assembly, a controller and a storage battery. The temperature control system comprises a semiconductor air-conditioner, an in-cabinet temperature instrument and an out-cabinet temperature instrument. Through the design of the solar electrical cabinet, the solar electrical cabinet can assist power supply, the refrigeration or heating function on the interior of the solar electrical cabinet is achieved through the temperature control system, it is accordingly guaranteed that the temperature in the solar electrical cabinet is within the working temperature range of an electrical apparatus element, and the situation that safety operation of an electrical power system is influenced by advanced ageing breakdown and the like of the electrical apparatus element at the extra-low or extra-high temperature is avoided.

Description

[0001] technical field [0002] The invention relates to an electric cabinet, in particular to a solar electric cabinet with automatic temperature adjustment function. Background technique [0003] At present, the outdoor electrical cabinets used in power systems are placed outdoors for many years, and electrical components such as switches, switches, and terminal blocks are installed in the electrical cabinets. The normal operating temperature range of general electrical components is -5°C-70°C. Although the electrical cabinet is a semi-closed device, the temperature inside the cabinet will exceed these electrical components throughout the year, especially in extremely hot and cold weather. The working temperature range accelerates the aging of these electrical components, affects the performance, causes accidents such as switch tripping or mis-closing, and terminal breakdown, which brings great hidden dangers to the safe operation of the power system.
