Description

Technical Field

[0001] This utility model relates to the field of wireless temperature measurement technology for moving contacts of drawer switches, and more specifically, to a wireless temperature measurement device for moving contacts of drawer switches. Background Technology

[0002] In industries such as power and chemical engineering, due to various factors, when the load on the drawer switches in the power distribution room is large, the contact points of the drawer switches may overheat due to poor contact during long-term operation. These heat-generating parts are all enclosed inside the drawer, making it difficult for maintenance personnel to monitor, detect, and handle them in time when the power is on. This leads to the accelerated oxidation of the contact surface, creating a vicious cycle. After a period of time, this can cause arcing, discharge faults, or even short circuits and fires, seriously affecting the safe and stable operation of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a wireless temperature measuring device for the moving contact of a drawer switch, which can monitor the temperature of the moving contact of the drawer switch in real time, and can promptly alarm when the temperature of the moving contact of the drawer switch exceeds the temperature threshold, and no additional power supply is required during the entire detection process.

[0004] To achieve the purpose of this utility model, the technical solution adopted is as follows: a wireless temperature measuring device for the moving contact of a drawer switch, including a temperature measuring module, the measuring end of which is attached to the busbar of the moving contact of the drawer switch; the temperature measuring module also has a conductive clamp, which is electrically connected to the temperature measuring module, and the clamp holds and fixes the temperature measuring module to the busbar of the moving contact of the drawer switch and makes contact with the busbar of the moving contact of the drawer switch.

[0005] Furthermore, the clamp includes a conductive strip A and a conductive strip B, which are respectively connected to two terminals of the temperature measuring module. The extended end of the conductive strip A has a fixing sleeve for the conductive strip B to pass through, and the fixing sleeve has a bolt for tightening and fixing the conductive strip B and the conductive strip A together.

[0006] Furthermore, both conductive strip A and conductive strip B are equipped with silicone pads, and the silicone pads are fitted with the edges of the busbar of the drawer switch moving contact.

[0007] Furthermore, the silicone pad is inserted onto conductive strip A and conductive strip B.

[0008] Furthermore, both conductive strip A and conductive strip B are alloy sheets.

[0009] Furthermore, the inner surface of the silicone pad has convex ridges arranged at intervals, and the axial direction of the convex ridges is consistent with the axial direction of the busbar of the drawer switch moving contact.

[0010] Furthermore, insulating tape is wrapped around both the clamp and the temperature measuring module.

[0011] Furthermore, there is at least one temperature measuring module, and each temperature measuring module corresponds one-to-one with the busbar of the drawer switch moving contact.

[0012] Furthermore, it also includes a wireless online temperature measurement and detection device, an alarm module, and a remote DSC system monitoring terminal, with the output of the temperature measurement module connected to the input of the wireless online temperature measurement and detection device, and the output of the wireless online temperature measurement and detection device connected to the input of the alarm module and the input of the remote DSC system monitoring terminal.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the measuring end of the temperature measuring module is attached to the busbar of the moving contact of the drawer switch, and a conductive clamp is used to hold and fix the temperature measuring module on the busbar of the moving contact of the drawer switch. This not only eliminates the need for an additional power supply for the temperature measuring module, but also enables real-time monitoring of the temperature of the busbar on the moving contact of the drawer switch.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0024] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 As shown, the present invention provides a wireless temperature measuring device for a drawer switch moving contact, including a temperature measuring module 5. The temperature measuring module 5 is a direct use of existing technology, and the temperature measuring module 5 is installed on the busbar 2 of the drawer switch moving contact 1, with the detection end of the temperature measuring module 5 in contact with the busbar 2 of the drawer switch moving contact 1, so that the temperature of the drawer switch moving contact 1 is transmitted to the temperature measuring module 5 through the busbar 2, thereby enabling the temperature measuring module 5 to detect the temperature of the drawer switch moving contact 1.

[0026] To ensure the fixation and power supply of the temperature measuring module 5, a clamp 3 is also provided on the temperature measuring module 5. The clamp 3 is made of conductive material, giving it conductivity. The clamp 3 is electrically connected to the temperature measuring module 5, allowing it to transmit electrical energy to the temperature measuring module 5. The temperature measuring module 5 operates based on the electrical energy transmitted by the clamp 3, thus eliminating the need for an additional power supply. At the same time, the clamp 3 tightly fixes the temperature measuring module 5 to the busbar 2 of the drawer switch moving contact 1. When clamping the temperature measuring module 5, the clamp 3 contacts the busbar 2 of the drawer switch moving contact 1, allowing the electrical energy received by the drawer switch to be transmitted to the temperature measuring module 5 through the clamp 3. This enables the temperature measuring module 5 to operate when the drawer switch is energized, allowing the temperature measuring module 5 to simultaneously detect the temperature of the busbar 2 on the drawer switch moving contact 1 while the drawer switch is operating, facilitating real-time temperature monitoring of the drawer switch moving contact 1.

[0027] In this utility model, such as Figure 2The clamp 3 shown includes conductive strip A31 and conductive strip B32. Conductive strip A31 and conductive strip B32 are respectively connected to two terminals of the temperature measuring module 5. Conductive strip A31 and conductive strip B32 extend from opposite sides of the temperature measuring module 5, and the extension end of conductive strip A31 has a fixing sleeve 33. The extension end of conductive strip B32 can pass through the fixing sleeve 33. By pulling conductive strip B32, the size of the ring formed by conductive strip A31 and conductive strip B32 can be adjusted. Simultaneously... The fixing sleeve 33 is also provided with a threaded hole, and a bolt 34 is installed in the threaded hole. By tightening the bolt 34, the tail of the bolt 34 can be inserted into or removed from the fixing sleeve 33. This allows the bolt 34 to tighten and fix the conductive strip B32 to the fixing sleeve 33, or the bolt 34 to loosen its pressure on the conductive strip B32, so that the conductive strip A31 and the conductive strip B32 together hold tightly on the busbar 2 of the drawer switch moving contact 1 and remain secure, thus ensuring the stability of the temperature measuring module 5 installation. Because the fixing sleeve 33 presses against the busbar 2 of the drawer switch moving contact 1 while the bolt 34 is tightened, the clamp 3 is in contact with the busbar 2 of the drawer switch moving contact 1, thus ensuring the transmission of electrical energy.

[0028] To prevent conductive strips A31 and B32 from damaging the edges of the busbar 2 on the moving contact 1 of the drawer switch, silicone pads 4 are installed on conductive strips A31 and B32. After conductive strips A31 and B32 are tightly fixed to the busbar 2 on the moving contact 1 of the drawer switch, one silicone pad 4 is placed between conductive strip A31 and the edge of the busbar 2 on the moving contact 1 of the drawer switch, and the other silicone pad 4 is placed between conductive strip B32 and the edge of the busbar 2 on the moving contact 1 of the drawer switch. This prevents conductive strips A31 and B32 from pressing on the edges of the busbar 2 on the moving contact 1 of the drawer switch when they are tightly fixed to it, thus preventing damage to the busbar 2 on the moving contact 1 of the drawer switch.

[0029] In this invention, to facilitate the installation and adjustment of the silicone pad 4, the silicone pad 4 is rectangular and has a through hole, allowing it to be inserted onto the conductive strips A31 and B32. During use, the operator can slide the silicone pad 4 on the conductive strips A31 and B32 according to their alignment with the busbar 2 on the drawer switch moving contact 1. This allows the silicone pad 4 to be positioned between the edges of the conductive strips A31 and B32, and between the conductive strips B32 and B32 on the drawer switch moving contact 1, making its use more flexible.

[0030] To improve the anti-slip performance between the silicone pad 4 and the busbar 2 on the moving contact 1 of the drawer switch, the inner side of the silicone pad 4 also has spaced-apart raised ridges. When the silicone pad 4 is placed between the conductive strip A31 and the edge of the busbar 2 on the moving contact 1 of the drawer switch, and between the conductive strip B32 and the edge of the busbar 2 on the moving contact 1 of the drawer switch, the length direction of the raised ridges is consistent with the length direction of the busbar 2 on the moving contact 1 of the drawer switch. The edge of the busbar 2 on the moving contact 1 of the drawer switch is engaged between two adjacent raised ridges on the silicone pad 4, which not only prevents it from being pressed tightly against the edge of the busbar 2 on the moving contact 1 of the drawer switch, but also allows the conductive strips A31 and B32 to hold tightly against the busbar 2 on the moving contact 1 of the drawer switch, thus improving the fastening effect of the temperature measuring module 5.

[0031] In this invention, the silicone pad 4 can also be replaced by an insulating rubber pad of the same shape, which can achieve the same function as the silicone pad 4. Meanwhile, the conductive strips A31 and B32 in this invention are both made of alloy sheets, ensuring their conductivity while increasing their structural strength. Of course, the conductive strips A31 and B32 in this invention can also be made of other conductive materials.

[0032] Since conductive strips A31 and B32 need to have conductive function, in order to make this utility model safer to use, when the clamp 3 is tightly clamped on the busbar 2 of the moving contact 1 of the drawer switch and the measuring end of the temperature measuring module 5 is in close contact with the busbar 2 of the moving contact 1 of the drawer switch, insulating tape is wrapped around both the clamp 3 and the temperature measuring module 5. The number of turns of insulating tape can be adjusted at will, as long as the outside of the clamp 3 is completely covered.

[0033] In this invention, the number of temperature measuring modules 5 can be selected according to the number of busbars 2 on the moving contact 1 of the drawer switch. For example, when there are multiple busbars 2 on the moving contact 1 of the drawer switch, there can also be multiple temperature measuring modules 5. In this case, the temperature measuring modules 5 correspond one-to-one with the busbars 2 on the moving contact 1 of the drawer switch, and each temperature measuring module 5 detects the temperature of the corresponding busbar 2 on the moving contact 1 of the drawer switch, thereby monitoring the temperature of the drawer switch.

[0034] In this utility model, such as Figure 3 As shown, the wireless temperature measurement device for the drawer switch moving contact 1 also includes a wireless online temperature measurement detection device 6, an alarm module 7, and a remote DSC system monitoring terminal 8. The wireless online temperature measurement detection device 6 is wirelessly connected to the temperature measurement module 5, and the wireless transmitter of the temperature measurement module 5 is wirelessly connected to the wireless receiver of the wireless online temperature measurement detection device 6. One pin of the output of the wireless online temperature measurement detection device 6 is wiredly connected to the input of the alarm module 7, and the other pin of the output of the wireless online temperature measurement detection device 6 is wiredly connected to the input of the remote DSC system monitoring terminal 8.

[0035] In this invention, the temperature measuring module 5 is a wireless temperature sensor, model WC-01, and the alarm module 7 can be an audible and visual alarm.

[0036] During installation, the measuring end of the temperature measuring module 5 is attached to the busbar 2 of the moving contact 1 of the drawer switch, and the conductive strips A31 and B32 are placed on the busbar 2 of the moving contact 1 of the drawer switch. The silicone pads 4 on the conductive strips A31 and B32 are adjusted so that the two silicone pads 4 are respectively placed between the conductive strip A31 and the edge of the busbar 2 on the moving contact 1 of the drawer switch, and between the conductive strip B32 and the edge of the busbar 2 on the moving contact 1 of the drawer switch; then, The extended end of the conductive strip B32 passes through the fixing sleeve 33. By pulling the conductive strip B32, the loop formed by the conductive strip A31 and the conductive strip B32 is tightly wrapped around the busbar 2 of the moving contact 1 of the drawer switch. Finally, the bolt 34 is tightened so that the tail of the bolt 34 extends into the fixing sleeve 33, thereby the bolt 34 can press and fix the conductive strip B32 to the fixing sleeve 33, so that the conductive strip A31 and the conductive strip B32 are tightly wrapped around the busbar 2 of the moving contact 1 of the drawer switch and remain secure.

[0037] When the drawer switch is powered on, the electrical energy of the drawer switch is transmitted to the temperature measuring module 5 through conductive strips A31 and B32, thereby powering the temperature measuring module 5. Since the measuring end of the temperature measuring module 5 is in close contact with the busbar 2 of the moving contact 1 of the drawer switch, the temperature of the busbar 2 on the moving contact 1 of the drawer switch is transferred to the temperature measuring module 5. After the temperature measuring module 5 detects the temperature of the busbar 2 on the moving contact 1 of the drawer switch, it transmits it to the wireless online temperature measuring device 6 through 433 Hz wireless communication. The wireless online temperature measuring device 6 compares the temperature information detected by the temperature measuring module 5 with the set temperature threshold. If the received temperature information value exceeds the set temperature threshold, the wireless online temperature measuring device 6 sends an alarm signal to the alarm module 7, and the alarm module 7 sounds an alarm. If the received temperature information value does not exceed the set temperature threshold, the wireless online temperature measuring device 6 does not send an alarm signal to the alarm module 7.

[0038] Of course, after the temperature module detects the temperature of the busbar 2 on the moving contact 1 of the drawer switch and transmits it to the wireless online temperature measurement device 6, the wireless online temperature measurement device 6 transmits it to the remote DSC system monitoring terminal 8, so that the staff can check the operating temperature of the drawer switch through the remote DSC system monitoring terminal 8. At the same time, in the process of comparing the temperature information detected by the temperature measurement module 5 with the set temperature threshold, the wireless online temperature measurement device 6 also transmits the comparison result to the remote DSC system monitoring terminal 8, so that the staff can check whether the temperature of the drawer switch is too high through the remote DSC system monitoring terminal 8.

[0039] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
