Electrical cabinet apparatus with automatic protection function

Abstract

The invention discloses an electrical cabinet apparatus with an automatic protection function. The electrical cabinet apparatus comprises a ground-buried protective cabinet; the ground-buried protective cabinet is provided with a hoisting oil cylinder; the bottom of the hoisting oil cylinder is fixed on the electrical cabinet; the electrical cabinet can be lifted under the action of the lifting oil cylinder; when the electrical cabinet is in an upper port position, a board-lifting motor in the electrical cabinet is started to lift a one-way bent type supporting board by a pulling rope; when the supporting board is lifted to a certain height, the supporting board is put down; the ground around the upper port of the ground-buried protective cabinet is pressed by the one-way bent type supporting board, and the electrical cabinet is supported; a telescopic cover board is in a telescopic state, and the electrical cabinet works on the ground; a wind speed sensor and a humidity sensor constantly collect the outdoor wind speed and humidity; when a single chip microcomputer circuit judges that rain or heavy wind is coming based on the received data, the single chip microcomputer circuit enables the electrical cabinet to enter the ground-buried protective cabinet, and the upper port of the ground-buried protective cabinet is covered by the telescopic cover board. Therefore, the electrical cabinet apparatus can be wind-preventing and rain-preventing, so that aging speed of electrical apparatus elements in the electrical cabinet can be slowed down.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet device with an automatic protection function. Background technique [0002] 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, terminal breakdown, etc., and brings great hidden dangers to the safe operation of the power system. If the temp...

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.
