Problems solved by technology
[0004] 1. The control board has poor versatility, and one control board cannot be used to control the start and stop of the air conditioner and the start and stop of the exhaust fan;
[0005] 2. When changing the parameters of the control panel, it is necessary to open the door of the relay protection cabinet one by one, and then re-enter the parameters, which not only wastes manpower, but also makes it easy not to touch the equipment in the cabinet when setting the parameters

Embodiment Construction
[0017] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.
[0018] Please refer to Figure 1-3 , the embodiment of the present invention includes:
[0019] A temperature control system for a back-to-back relay protection cabinet in a substation, which is used to adjust the temperature inside the protection cabinet by controlling the start and stop of the air conditioner and exhaust fan in the back-to-back relay protection cabinet without opening the cabinet door. The monitoring module outside the relay protection cabinet and the control module installed in the back-to-back relay protection cabinet, the monitoring module and the control module are connected through carrier communication.
[0020] The control module includes a control module housing 200, a processor 210 installed in the control module housing 200, an RS-485 hub 230, a first carrier ...

The invention discloses a substation back-to-back relay protection cabinet temperature control system. The substation back-to-back relay protection cabinet temperature control system is used for adjusting the temperature of an air conditioner and the startup and shutdown of an exhaust fan in a back-to-back relay protection cabinet with a cabinet door closed. The substation back-to-back relay protection cabinet temperature control system includes a monitoring module installed outside the back-to-back relay protection cabinet and a control module installed in the back-to-back relay protection cabinet; and the monitoring module communicates with the control module. With the substation back-to-back relay protection cabinet temperature control system provided by the invention adopted, the startup and shutdown of air conditioners and exhaust fans in the control modules in a plurality of back-to-back relay protection cabinets and temperature in the cabinets can be monitored and adjusted in real time when cabinet doors are not opened.
Description
technical field [0001] The invention relates to the field of protection cabinets in substations, in particular to a temperature control system for back-to-back relay protection cabinets in substations. Background technique [0002] In order to save space and investment costs, substation relay protection cabinets often use back-to-back splicing of multiple protection cabinets together. However, after long-term operation, it is found that the heat dissipation performance of the relay protection cabinet with this connection method is poor, which may easily lead to high temperature in the cabinet and affect the normal operation of the equipment in the cabinet. [0003] In order to solve the problem of poor heat dissipation of back-to-back electromechanical protection cabinets in substations, it is generally used to install exhaust fans or air conditioners in the cabinets to achieve cooling effects. However, the control boards of air conditioners and exhaust fans suitable for th...
