Description

Technical Field

[0001] The present invention relates to the technical field of temperature measurement, and in particular to a temperature measuring device. Background Art

[0002] Gas Insulated Substation (GIS) equipment is one of the most important equipment in GIS substations. It is a fully enclosed metal shell that contains conductors, high-voltage electrical appliances, etc., and is filled with sulfur hexafluoride six (SF6) gas at a certain pressure to maintain insulation. Errors in factory quality and installation quality may cause hidden dangers inside GIS equipment, such as partial discharge caused by conductor burrs, poor contact caused by installation errors, and discharge caused by internal metal particles. In recent years, there have been a number of equipment explosions caused by ablation at the connection of the conductive circuit conductors inside GIS equipment, resulting in emergency power outages.

Figure 1 is a module schematic diagram of a temperature measuring device provided by an embodiment of the present invention, Figure 2 This is the installation diagram of the temperature measuring device, optional, refer to Figure 1 and Figure 2 The temperature measuring device includes: a measuring module 10 and a measuring host 20; wherein the measuring module 10 is arranged inside the gas-insulated metal-enclosed switch GIS device, and the measuring host 20 is arranged outside the GIS device;

[0046] The measurement module 10 includes an integrated chip 11, a first communication unit 12 and at least two flexible heat source power generation chips 13; the at least two flexible heat source power generation chips 13 are electrically connected to at least two first ends of the integrated chip 11, respectively, and the second end of the integrated chip 11 is electrically connected to the first communication unit 12; the at least two flexible heat source power generation chips 13 are arranged at different positions of the preset components inside the GIS device;

[0047] The flexible heat source power generation chip 13 is used to output a first current to the integrated chip 11 when it detects that the temperature of a preset component is greater than a preset value;

[0048] When the integrated chip 11 receives the first current, the first communication unit 12 is controlled to send a first signal to the measuring host 20;

[0049] The measuring host 20 is used to send a control signal to the first communication unit 12 when receiving the first signal;

[0052] The flexible heat source power generation chip 13 that does not output current is used to output a second current to the integrated chip according to the temperature of the preset component after startup;

[0053] The integrated chip 11 is used to control the first communication unit 12 to send a second signal to the measurement host 20 when receiving the second current;

[0054] The measuring host 20 is used to determine the temperature state of the preset component according to the first signal and the second signal. Among them, the integrated chip 11 can be a control chip. The first communication unit 12 adopts a 2.4G medium-to-short distance wireless signal transmission method, which has low energy consumption and a high overall data transmission rate. The device system can respond instantly, and allows multiple systems or multiple execution sub-machines to coexist, and has anti-interference capabilities. The flexible heat source power generation chip 13 is usually composed of two conductors or semiconductors of different materials to form a thermocouple. When there is a temperature difference at the junction of the two conductors, an electric potential difference will be generated in the circuit, thereby driving current to pass.

[0055] Specifically, the measuring module 10 is installed inside the GIS device, and includes an integrated chip 11, a first communication unit 12 and at least two flexible heat source power generation chips 13. The flexible heat source power generation chips 13 are placed at different positions of the preset components inside the GIS device. The measuring host 20 is located outside the GIS device and receives signals from the measuring module 10. The flexible heat source power generation chips 13 continuously monitor the temperature of the preset components at their locations. When any flexible heat source power generation chip 13 detects that the temperature of the preset components at its location is greater than a preset value, the flexible heat source power generation chip 13 outputs a first current to the integrated chip 11. After the integrated chip receives the first current, the integrated chip 11 controls the first communication unit 12 to send a first signal to the measuring host 20 located outside the GIS device to notify the measuring host 20 that there is a temperature abnormality. After the measuring host 20 receives the first signal, the measuring host 20 sends a The control signal requires the measurement module 20 to start the flexible heat source power generation chip 13 that does not output current for secondary measurement; after receiving the control signal from the measurement host 20, the first communication unit 12 transmits it to the integrated chip 11; the integrated chip 11 controls the flexible heat source power generation chip 13 that does not output current to start according to the control signal; the started flexible heat source power generation chip 13 outputs a second current to the integrated chip 11 according to the current temperature; after receiving the second current, the integrated chip 11 controls the first communication unit 12 to send a second signal to the measurement host 20; after receiving the second signal, the measurement host 20 combines the first signal and the second signal and uses an internal algorithm to analyze and compare; according to the analysis results, the measurement host 20 determines the temperature status of the preset components inside the GIS equipment, including whether it exceeds the safety range and whether there are abnormal hot spots, etc.; if the temperature is abnormal, the measurement host 20 can further trigger an alarm mechanism.

[0056] Exemplarily, taking one end conductor L1 as an example, the flexible heat source power generation chips A1 and A2 are installed on both sides of the conductor. When one end of the conductor is overheated, the flexible heat source power generation chip A1 will emit a first current, and at the same time start the first communication unit 12 to send a signal to the measuring host 20; the measuring host 20 sends a signal to the flexible heat source power generation chip A2 to start, and the flexible heat source power generation chip A2 will send a second current to the measuring host 20. The control unit in the measuring host 20 calculates the difference between the first current and the second current. When the current difference between the first current and the second current is too large, the measuring host 20 will determine that one end of the conductor may be overheated. When the current difference between the first current and the second current is not large, the measuring host 20 will determine that the temperature rise is due to the high load.

[0057] The temperature measuring device provided in the embodiment of the present invention includes a measuring module 10 and a measuring host 20; wherein the measuring module 10 is arranged inside the gas-insulated metal-enclosed switch GIS device, and the measuring host 20 is arranged outside the GIS device, and the measuring module 10 and the measuring host 20 realize data interaction and instruction transmission through a communication unit; the measuring module 10 includes an integrated chip 11, a first communication unit 12 and at least two flexible heat source power generation chips 13, and the integrated chip 11, the first communication unit 12 and the at least two flexible heat source power generation chips 13 jointly complete the real-time monitoring of the temperature of the preset component; the at least two flexible heat source power generation chips 13 are respectively electrically connected to at least two first ends of the integrated chip 11, and the second end of the integrated chip 11 is electrically connected to the first communication unit 12; at least two flexible heat source power generation chips 13 are arranged at different positions of the preset component inside the GIS device; the flexible heat source power generation chip 13 is used to detect the temperature of the preset component. When the integrated chip 11 is at a preset value, the first current is output to the integrated chip 11. When the integrated chip 11 receives the first current, the first communication unit 12 is controlled to send a first signal to the measuring host 20. The measuring host 20 is used to send a control signal to the first communication unit 12 when receiving the first signal. The first communication unit 12 is used to transmit the control signal to the integrated chip 11 after receiving the control signal. After receiving the control signal, the integrated chip 11 is used to control the flexible heat source power generation chip 13 that does not output current to start. The flexible heat source power generation chip 13 that does not output current is used to start and output a second current to the integrated chip 11 according to the temperature of the preset component. When the integrated chip 11 receives the second current, the first communication unit 12 is controlled to send a second signal to the measuring host 20. The measuring host 20 is used to determine the temperature state of the preset component according to the first signal and the second signal, which is helpful to timely discover and warn potential temperature problems and prevent failures or accidents caused by overheating of the equipment.

[0059] Specifically, the measuring host 20 receives the first signal and the second signal, calculates the difference between the two temperature signals, and after calculating the difference, the measuring host 20 compares the difference with a preset set value. If the difference between the first signal and the second signal is less than or equal to the set value, the measuring host 20 determines that the overall temperature of the preset component is relatively uniform and may be in an overheated state as a whole. At this time, the measuring host 20 records or marks the overheated state, which may trigger further inspection or processing procedures. If the difference between the first signal and the second signal is greater than the set value, the measuring host 20 determines that there is overheating in some areas of the preset component. The measuring host 20 will immediately issue an alarm signal to alert the operator or the system. The measuring host 20 can also trigger corresponding emergency treatment measures, such as shutdown inspection and cooling.

[0066] Specifically, the second communication unit 21 receives the first signal and the second signal, and transmits the received signal to the control unit 22 for processing. The control unit 22 determines whether the preset component is overheated as a whole or in part according to the comparison result of the signal difference and the set value.
