Embodiment 1

[0030] A battery is installed inside the controller 11, and the output end of the battery is electrically connected with the controller 11, exhaust fan, camera, infrared thermal imager, flashing light, buzzer, relay and refrigerator 15.

[0031] working principle:

[0032] When in use, the signal receiving module inside the controller 11 transmits the information of the camera of the collection device 9 to collect the marking strip 8 and the thermal imaging information collected by the infrared thermal imager to the mark recognition module and the storage module, and then the mark recognition module is used for the collected Identify the marking strip 8 information, and at the same time, the model building module establishes a plane model for the electrical installation board 2 according to the marking strip 8 information identified by the marking identification module and the thermal imaging information collected by the infrared thermal imager, and then the signal comparison m...

Abstract

The invention relates to the technical field of switch cabinets, in particular to an overheating protection device for a switch cabinet. The conventional switch cabinet has the disadvantages that theoverheat protection is insufficient when the cabinet is used, and that the temperature change state of the internal components cannot be effectively analyzed during the using. The invention provides the following technical scheme: the device comprises a switch cabinet body; an electrical appliance mounting plate arranged in the vertical direction is mounted inside the switch cabinet body; one sideof the electrical appliance mounting plate is provided with U-shaped supports, which are arranged equidistantly in the vertical direction; and division plates are vertically mounted between the adjacent supports. According to the overheating protection device for the switch cabinet, the device is simple in structure, convenient and fast to operate. On the one hand, the device can effectively monitor the temperature change of the electrical appliances in the switch cabinet during the operation, thereby providing a data basis for the performance analysis of the switch cabinet, and providing a theoretical basis for the subsequent upgrade and the improvement of the switch cabinet. On the other hand, the device can effectively and quickly reduce the temperature of the electrical appliances inside the switch cabinet and the occurrences of the power failure of the switch cabinet, thereby reducing the loss caused by the power failure.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an overheat protection device for a switch cabinet. Background technique [0002] The switch cabinet is used to place various relay protection devices or other electrical equipment, and a large amount of heat will be generated under the operation of various electrical equipment. When the ambient temperature in the switch cabinet is too high, it is easy to cause the relay protection device to crash, and even shorten its service life; [0003] The application number is: 201721087397.8 A switch cabinet overheat protection device, including battery G1, first light-emitting diode D1, second light-emitting diode D2, relay K1, transistor T1, transistor T2 and three thermistors RT1, RT2, RT3 , the three thermistors RT1, RT2, and RT3 are set in the upper, bottom and middle parts of the switch cabinet, and are connected in series in sequence. Under normal conditions in the switch ...
