Energy-saving variable-frequency industrial electric appliance control cabinet

Abstract

The invention relates to an energy-saving variable-frequency industrial electric appliance control cabinet, and belongs to the frequency conversion control cabinet technical field. The energy-saving variable-frequency industrial electric appliance control cabinet comprises a cabinet body, one side of the cabinet body is provided with an opening and a door body closing the opening, cooling water pipes are respectively fixed on two side inner walls of the cabinet body, the side wall of the cabinet body far away from the opening is provided with a ventilation grating communicated with the outside, and the inner wall of the cabinet body far away from the opening is fixed with a heat conduction sheet; a circulating water tank is arranged at the bottom of the cabinet body, two ends of the cooling water pipe are respectively communicated with the circulating water tank, and circulating water pumps are respectively arranged at the water inlet end and the water outlet end of the cooling water pipe; the energy-saving variable-frequency industrial electric appliance control cabinet further comprises a temperature detection module and a temperature control module; the temperature detection module detects the temperature in the cabinet body, the temperature control module recognizes and judges a temperature detection signal, and when the detected temperature value is larger than a water cooling temperature set value, the temperature control module controls the circulating water pump to be started to work. In the daily use process, the heat dissipation efficiency of the interior of the cabinet body is high, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of frequency conversion control cabinet equipment, in particular to an energy-saving frequency conversion industrial electrical appliance control cabinet. Background technique [0002] Electrical control cabinets are also called inverter control cabinets or inverter electric control cabinets, which are widely used in metallurgy, chemical industry, petroleum, water supply, and mining industries. The electrical control cabinet is designed according to the maximum load and a certain margin is added. In the actual working condition, the power of the inverter group inside the electrical cabinet changes with the power of the external load. In order to make the inverter group in the electrical control cabinet work well, cooling equipment is usually added to the electrical control cabinet, so that the heat inside the electrical control cabinet can be dissipated in time.
