Switch cabinet

Abstract

The invention discloses a switch cabinet which comprises a cabinet body, an air inlet tube, two air speed sensors, a first humidity sensor, a controller, a fan driving circuit, two heaters, a temperature sensor and a power supply, wherein a fan is arranged at the upper part of the air inlet tube; a plurality of air outlet channels are formed in the upper part of the air inlet tube; the two air speed sensors are respectively arranged at tail ends of any tow air outlet channels; the first humidity sensor is arranged at the inlet end of the air inlet tube; a second humidity sensor is arranged in the middle of the cabinet body; the controller is electrically connected with the two air speed sensors, the first humidity sensor and the second humidity sensor; the fan driving circuit is electrically connected with the controller and the fan; the heaters are arranged at the upper part of the cabinet body; the temperature sensor is arranged at the upper part of the cabinet body; and the power supply is used for supplying power to the heater and the controller. By adopting the structure, the temperature and the humidity in the cabinet are kept constant.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and variou...

AI Technical Summary

Problems solved by technology

[0004] The switchgear in the existing market has relatively simple internal protection equipment, which makes the temperature and humidity inside the cabinet fluctuate too much and cannot be kept constant. This will cause damage to the electrical components inside the cabinet and cause its circuit to malfunction. Short circuit, open circuit, etc., so that the whole switchgear is scrapped, and the cost is relatively high
