Dustproof ventilation electric power control cabinet

Abstract

The invention provides a dustproof ventilation electric power control cabinet, and relates to the technical field of electric power equipment. The dustproof ventilation electric power control cabinetcomprises a cabinet body, a controller, two pressure sensors connected with the controller, a temperature sensor, a controller and two alarms; the cabinet body is provided with a first air inlet and asecond air inlet which communicate with an air inlet mechanism, and an air outlet which communicates with an air outlet mechanism. One dust filtering mechanism is arranged between the first air inletand the air inlet fan of the air inlet mechanism; the other one dust filtering mechanism is arranged at the second air inlet; the pressure sensors detect a pressure numerical value on a filter element, the temperature sensor detects a temperature numerical value in the cabinet body, and the numerical value is transmitted to the controller; the controller controls the alarm to give an alarm and controls the air outlet motor of the air outlet mechanism to increase the rotating speed. The above arrangement can prevent the module of the electronic component from working in an overheat environmentfor a long time, improves the conditions of short circuit and aging failure of the component, and improves the safety of a power system.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a dustproof and ventilated power control cabinet. Background technique [0002] The power control cabinet is to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in the closed or semiclosed metal cabinet or on the screen width according to the requirements of electrical wiring. Safety of personal and surrounding equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations...
