Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a wireless monitoring device for the temperature rise of contacts of outdoor pole-mounted circuit breakers. Background Technology

[0002] An outdoor pole-mounted circuit breaker is a power protection device installed on outdoor supporting structures such as utility poles and towers. It is mainly used in power distribution lines to protect circuits from overload, short circuits, and other faults, and supports manual or automatic current interruption. Its core component is the contact, located inside an insulated casing, used for closing the circuit. In practical use, monitoring the temperature rise of the contacts is crucial, especially under high load or complex environmental conditions. Abnormal temperature rises can directly reflect problems such as equipment aging, poor contact, or overload, and if not addressed promptly, can even lead to serious malfunctions. Especially in smart grids, real-time contact temperature monitoring has become a core means of preventative maintenance. It can provide early warnings of potential faults several hours to days in advance, significantly reducing repair costs and power outage losses. However, traditional temperature rise monitoring methods require data transmission via data cables, which is inconvenient and poses a risk of leakage. Furthermore, maintenance is difficult and can easily damage the vacuum of the insulating casing, affecting the circuit breaker's lifespan. A new monitoring device is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a wireless monitoring device for the contact temperature rise of an outdoor pole-mounted circuit breaker. The device includes a clamp base, with two semi-circular bodies of the clamp base fitting together in the middle of the insulating outer shell of the pole-mounted vacuum circuit breaker. The middle of the clamp base protrudes outward to form an annular chamber. Platforms are provided at the joints on both sides of the annular chamber. A wireless thermometer is installed on the outer end face of the first platform. The probe of the wireless thermometer extends into the insulating shell and is aligned with the contact. The wireless thermometer is equipped with a remote receiver, which is electrically connected to the monitoring platform. An evacuation pipe with a control valve is inserted into the end face of the second platform.

[0004] Furthermore, the wireless thermometer has a temperature display screen, and the two side plates of the wireless thermometer are connected to two semi-ring seats by bolts. The data cable on the back of the wireless thermometer enters the ring chamber through an opening on the end face of the platform, and the probe is connected to the end of the data cable.

[0005] Furthermore, the protrusions on both sides of the probe head can penetrate into the vertical waist hole of the insulating shell when it is vertical, and the threaded section at the tail of the probe is connected to the fastening bolt.

[0006] Furthermore, the evacuation tube is provided with two parallel retaining rings at the end of the tube body. The evacuation tube between the two retaining rings is embedded in the semi-circular hole opened on the end face of the tail platform. The inner and outer retaining ring surfaces are respectively in contact with the inner and outer end faces of the platform. The threaded section at the beginning of the evacuation tube body can be connected to the air inlet pipe of an external vacuum pump.

[0007] Furthermore, the inner arc surface of the semi-ring seat of the clamp has several sealing grooves, which cooperate with the convex ring of the insulating outer shell. When the two semi-ring seats are closed, insulating sealant is applied to the mating surface.

[0008] The beneficial effects of this utility model are as follows: This utility model monitors the temperature of the circuit breaker contacts in real time through a probe, and then transmits the temperature rise information to the monitoring platform in real time through the transmitting antenna of the wireless temperature measuring device. The display screen of the wireless temperature measuring device will also display the temperature rise in real time, which is convenient for maintenance personnel to check. The position of the probe can be adjusted through the vertical waist hole. The device can be connected to an external vacuum pump through the evacuation pipe to evacuate the vacuum, ensuring the vacuum degree of the insulating shell and improving the service life of the circuit breaker.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 4 As shown, the wireless monitoring device for the contact temperature rise of an outdoor pole-mounted circuit breaker includes a clamp seat 1. The two semi-ring bodies of the clamp seat 1 are fitted together in the middle of the insulating shell 2 of the pole-mounted vacuum circuit breaker. Several sealing grooves 103 are formed on the inner arc surface of each semi-ring body of the clamp seat 1. The sealing grooves 103 engage with the convex rings of the insulating shell 2. When the two semi-ring bodies are fitted together, insulating sealant is applied to the mating surfaces. The middle part of the clamp seat 1 convexly forms an annular chamber 101, and platforms 102 are provided at the joints on both sides of the annular chamber 101.

[0018] In this embodiment, a wireless thermometer 3 is installed on the outer end face of the first platform 102. The wireless thermometer 3 has a temperature display screen. The ear plates on both sides of the wireless thermometer 3 are connected to two semi-ring seats by bolts. The data cable on the back side of the wireless thermometer 3 enters the ring chamber 101 through the opening on the end face of the platform 102. The end of the data cable is connected to the probe 301. When the probe 301 is vertical, the protrusions 302 on both sides of the head can pass into the vertical waist hole 201 of the insulating shell 2 and align with the contact 4. The threaded section of the tail of the probe 301 is threaded to the fastening bolt 8. The temperature rise data monitored by the probe 301 can be transmitted to the remote receiver 5 through the antenna of the wireless thermometer 3. The remote receiver 5 is electrically connected to the monitoring platform 6.

[0019] In this embodiment, a vacuum tube 7 with a control valve is inserted into the end face of the tail platform 102. The end of the vacuum tube 7 is provided with two parallel retaining rings 701. The vacuum tube 7 between the two retaining rings 701 is embedded in the semi-circular hole opened on the end face of the tail platform 102. The inner and outer retaining rings 701 are respectively attached to the inner and outer end faces of the platform 102. The threaded section at the beginning of the vacuum tube 7 can be connected to the air inlet pipe of an external vacuum pump.

[0020] The working principle of this utility model is as follows:

[0021] Fit one half-ring of the clamp seat 1 to the insulating shell 2. The protruding ring of the insulating shell 2 is embedded in the sealing groove 103. Connect the wireless thermometer 3 to the half-ring seat. Then, vertically insert the head of the probe 301 into the vertical waist hole 201. Rotate the probe 301 ninety degrees so that the protrusion 302 is locked on both sides of the vertical waist hole 201. Adjust the height of the probe 301 to align it with the contact 4. Then, tighten the fastening bolt 8 to fix the probe 301. Apply insulating sealant to the mating surface of the half-ring seat. After fitting the two half-ring seats together, tighten them with bolts. Open the control valve at the evacuation pipe 7. Connect the evacuation pipe 7 to the vacuum pump inlet pipe. Evacuate the insulating shell 2 and then close the control valve to complete the installation.

[0022] This invention monitors the temperature of the circuit breaker contact 4 in real time using probe 301, and then transmits the temperature rise information to the monitoring platform 6 in real time through the transmitting antenna of wireless thermometer 3. The display screen of wireless thermometer 3 will also display the temperature rise synchronously, making it convenient for maintenance personnel to check. The position of probe 301 can be adjusted through the vertical waist hole 201. The device can be connected to an external vacuum pump through the evacuation pipe 7 to evacuate the vacuum, ensuring the vacuum degree of the insulating shell 2 and improving the service life of the circuit breaker.
