Abstract

The invention provides a dust-proof and ventilated power control cabinet, which relates to the technical field of power equipment. The dust-proof and ventilated power control cabinet includes: a cabinet body, a controller, two pressure sensors connected to the controller, a temperature sensor, a controller and Two alarms; the cabinet body is provided with the first air inlet connected with the air inlet mechanism, the second air inlet and the air outlet connected with the air outlet mechanism; one of the dust filter mechanisms is set between the first air inlet and the air inlet mechanism Between the air inlet fans; another dust filter mechanism is set at the second air inlet; the pressure sensor detects the pressure value on the filter element, the temperature sensor detects the temperature value inside the cabinet, and the value is transmitted to the controller; the controller controls the alarm to send out Alarm and control the air outlet motor of the air outlet mechanism to increase the speed. The above settings can prevent the modules of electronic components from working in an overheated environment for a long time, improve the situation of short circuit, component aging and failure, and improve the safety of the 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...
