Embodiment Construction

[0028] In the process of realizing the present application, the inventors found that in order to meet the requirements of dustproof and fire prevention for electrical cabinets, at present, the electrical cabinets on rail vehicles usually adopt a sealed structure, and a fan is installed on the top of the cabinet, and the inside of the cabinet is blown by the operation of the fan. The heat generated by the device is taken away. For details, please refer to figure 1 , figure 1 Schematic diagram of the structure of the electrical cabinet provided for the prior art.

[0029] Please refer to figure 1 and figure 2 , figure 2 It is a schematic diagram of the heat dissipation control circuit in the electrical cabinet of the sealed structure provided by the prior art. exist figure 2 , close the fire control circuit breaker ( figure 2 After 49-F01) in the case of no fire, the coil of the alarm relay (49-K11) is energized and closed, the normally open contact is closed, the powe...

Abstract

The embodiment of the invention provides an electrical cabinet heat dissipation system, a control method and device and a storage medium. The electrical cabinet heat dissipation system comprises a control circuit and a fan. The control circuit is electrically connected with the fan and is used for controlling the fan to operate so as to dissipate heat of the electrical cabinet; the control circuit comprises a feedback loop, and the feedback loop is used for sending the operation state of the draught fan to the display screen through the network bus. The feedback loop is arranged in the control circuit to monitor the running state of the draught fan in the electrical cabinet in real time and send the running state of the draught fan to the display screen, so that a worker can obtain the running state of the draught fan in real time, once the electrical cabinet breaks down, measures can be taken quickly, potential safety hazards of a train are reduced, and safe operation of the train is guaranteed.

Description

technical field [0001] The present application relates to electrical equipment technology, in particular to an electrical cabinet heat dissipation system, control method, device and storage medium. Background technique [0002] With the development of rail transit, the requirements for the safety and stability of vehicles are getting higher and higher. The working life of electrical components has the most direct relationship with the working temperature. Poor heat dissipation of components is one of the reasons for the failure of electronic equipment. The electrical cabinet installed on the train is an integrated device for electrical system control, including auxiliary power supply, braking, network and other systems. The quality of its heat dissipation performance is related to the safety and stability of the entire train. Therefore, the temperature of the components in the electrical cabinet needs to be controlled below the effective working temperature to ensure the re...
