In specific implementation, the temperature measuring unit 10 is bound to the exposed contacts, busbar connections, outdoor knife switches, transformers and other equipment in the high-voltage switch cabinet by the binding belt 11, and there is no electrical connection between the temperature measuring unit 10 and the monitoring unit 20. One monitoring unit 20 can collect data of 198 temperature measuring points at most through the temperature measuring unit 10, which at least solves the problem that the temperature measuring device in the prior art cannot be used in a space with strong electromagnetic noise interference and high voltage due to electromagnetic interference. In actual applications, the utility model can detect potential thermal faults in time through real-time monitoring, avoid accidents such as power outages or equipment damage caused by equipment overheating, and reduce maintenance costs and equipment replacement costs. Secondly, the automation and intelligent features of the system reduce the workload of manual inspections, improve work efficiency, and reduce labor costs. Finally, through the accumulation and analysis of data, it can provide a scientific basis for equipment optimization and upgrading, which helps to improve the overall performance and life of power equipment.

[0022] Preferably, the material of the binding belt 11 is made of high temperature resistant silicone. The temperature measurement range is 0℃~+120℃, the measurement accuracy is ±1℃(0~75℃), ±2℃(75~120℃), the default sampling frequency is 1 minute, the maximum distance of wireless transmission is 1200m, the battery life is 4 years, the size of the temperature measuring unit 10 is 40mm×24mm×67mm, and the total length of the binding belt is 480mm.

[0023] Specifically, the monitoring unit 20 can display the working status of the temperature measuring unit 10, the temperature display of the test point, alarm, output, event record and data record. The default value of the temperature warning is 50°C, and the default alarm value is 60°C. The temperature warning value and alarm value can be set independently. When a temperature alarm event occurs, the temperature alarm output relay dry contact is closed and a beeping alarm sound prompt is issued, and the temperature alarm is displayed in red at the bottom of the main interface; when the battery voltage value is lower than 2.2V, the battery voltage low alarm output relay dry contact is closed, and the battery voltage low alarm is displayed in red at the bottom of the main interface. The monitoring unit 20 can save up to 198 records. When more than 198 records are recorded, the earliest record is automatically overwritten, and each sampling point only records the most recent alarm.

[0024] The temperature measurement unit 10 is directly installed on each high-voltage switch, busbar joint, outdoor knife switch or transformer.

The circumferential dimension of the raised ring 113 is greater than the internal dimension of the installation opening 114 so that the raised ring 113 is engaged with the installation opening 114 when the buckling belt 111 is extended into the installation opening 114. When the mounting belt 111 is inserted into the mounting opening 114 of the mounting belt 112 , the plurality of raised rings 113 can adjust the mounting position of the mounting belt 111 in the mounting opening 114 according to different positions, so as to be suitable for different installation environments.

After the buckle belt 111 is fixed on the installation belt 112, the part of the buckle belt 111 extending outside the installation opening 114 is tied up or cut off.

[0029] like Figure 5 As shown, the temperature measurement unit 10 includes a temperature sensor 101, a processing circuit 102, and a wireless transmitting circuit 103. The temperature sensor 101 is connected to the processing circuit 102 and the wireless transmitting circuit 103. The temperature sensor 101 is used to measure the temperature of the point to be measured. The processing circuit 102 is used to filter and modulate and amplify the measurement data of the temperature sensor 101. The wireless transmitting circuit 103 is used to transmit the electrical signal filtered and modulated and amplified by the processing circuit 102 to the monitoring unit 20.

[0030] Specifically, the temperature measuring unit 10 can also monitor the power supply voltage value of the temperature sensor 101 itself and the signal transmission strength of the wireless transmission circuit 103 in real time.

[0031] The monitoring unit 20 is mounted on the wall of the main control room by screws.
