Description

Technical Field

[0001] This invention relates to the field of power system technology, and specifically provides a power system relay protection early warning device. Background Technology

[0002] Relays are widely used in power systems. To ensure safe operation, it is now necessary to provide protection and early warning for relays.

[0003] When the cable is clamped to the relay, the cable's outer sheath is removed to connect and conduct electricity to the relay's internal terminals. When overloaded, the connection can easily spontaneously combust due to high temperatures, severely affecting power usage. If this is detected too slowly, it's unimaginable how much public property will be wasted. Therefore, we need to optimize the existing technology. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a power system relay protection early warning device.

[0005] To achieve the above objectives, the present invention provides a power system relay protection early warning device, including a relay. Abutment bars extend from both sides of the relay. A fixing frame is provided on the lower outer side of the relay. The upper ends of the fixing frame are connected to the relay via connecting components. A temperature alarm is mounted inside the fixing frame. Multiple contact components are provided inside one side of the temperature alarm. Connecting seats are fixedly sleeved on the outer sides of each of the multiple contact components. A sliding groove is formed on the lower inner side of the connecting seat. A sliding block is slidably connected inside the sliding groove. A booster pump is connected to one side of the sliding block via a fixedly installed connecting column. A connecting pipe is connected to one end of the booster pump, and self-protection components are provided at both ends of the connecting pipe.

[0006] Preferably, the connecting assembly includes a mounting base fixedly installed above one end of the fixing frame, a connecting block being slidably installed on the inner side of the mounting base through an opening in the sliding cavity, one end of the inner surface of the connecting block engaging with the outer side of the corresponding abutment bar, and a pressing component being provided on the top of the abutment bar at the position corresponding to the connecting block.

[0007] Preferably, the extrusion assembly includes guide rods vertically installed on the top of both sides of the abutment bar, with a retainer slidably connected to the outer side of both guide rods, and a tension spring provided on the outer side of each guide rod. The two ends of the tension spring are respectively connected to the outer wall of the retainer bar and the side of the abutment bar that are close to each other, and the retainer bar is movably engaged on the outer side of the connecting block.

[0008] Preferably, each of the plurality of contact components includes a smoke sensor fixedly installed on the outer wall of one side of the temperature alarm, a sensing head fixedly installed on one side of the smoke sensor, and a connecting seat fixedly fitted on the outside of the smoke sensor.

[0009] Preferably, the self-protection component includes a nozzle connected to and installed inside one end of a connecting pipe, an arc-shaped pipe connected to and installed on one side of the nozzle, and a sealing element provided on the inner side of one end of the arc-shaped pipe.

[0010] Preferably, the sealing element includes a sealing plug, which is movably engaged with the inner side of one end of the arc-shaped tube.

[0011] Preferably, the arc-shaped tube has a cavity inside, and a spraying element is provided inside one side of the nozzle.

[0012] Preferably, the spraying component includes multiple sets of nozzles, which are arranged at equal intervals along the arc-shaped trajectory inside the spray pipe. Both ends of one side of the slide are threaded with pins, and the ends of the pins abut against the outer side of the connecting seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By installing a mounting bracket below the relay connection, the self-protection component can be placed on the outside of the cable. When the temperature at the connection between the cable and the relay is too high, the temperature alarm will automatically sound an alarm. If the situation worsens before the staff arrives, the smoke sensor will detect the smoke through the sensor head. At this time, the booster air pump can spray the pre-filled dry powder into the cable connection through the connecting pipe into the arc-shaped pipes and nozzles at both ends, reducing the probability of fire and enabling timely fire source control.

[0015] 2. The mounting base and the internal sliding connecting block can be quickly engaged with the outside of the abutment bar. The corresponding card holder is pulled by the user to separate from the outside of the abutment bar. When the connecting block slides to the outside of the abutment bar, the card holder is released and reset under the contraction of the tension spring, so that the card holder is pressed against the outside of the connecting block for fixation. This method is convenient for installation and disassembly. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0025] like Figures 1-6 The power system relay protection early warning device shown includes a relay 1, with abutment bars 2 extending from both sides of the relay 1. A fixing frame 3 is provided on the lower outer side of the relay 1. The upper ends of the fixing frame 3 are respectively connected to the relay 1 through the provided connecting components. A temperature alarm 6 is installed inside the fixing frame 3. Multiple contact components are provided inside one side of the temperature alarm 6. A connecting seat 12 is fixedly sleeved on the outer side of each of the multiple contact components. A sliding groove 13 is opened on the lower inner side of the connecting seat 12. A sliding block 23 is slidably connected inside the sliding groove 13. A booster air pump 18 is connected to one side of the sliding block 23 through a fixedly installed connecting post 21. A connecting pipe 19 is connected to one end of the booster air pump 18. Self-protection components are provided at both ends of the connecting pipe 19.

[0026] By opening a groove 13 inside the connector 12, the self-protection component, the connecting pipe 19, and the booster pump 18 can be easily moved closer to the stripped part of the cable, thereby providing better early warning.

[0027] The connecting assembly includes a mounting base 8 fixedly installed above one end of the mounting frame 3. A connecting block 7 is slidably installed on the inner side of the mounting base 8 through a sliding cavity 24. The inner surface of one end of the connecting block 7 is engaged with the outer side of the corresponding abutment 2. A pressing component is provided on the top of the abutment 2 at the position corresponding to the connecting block 7.

[0028] The extrusion assembly includes guide rods 11 that are vertically installed on the top of both sides of the abutment bar 2. The outer sides of the two guide rods 11 are slidably connected to a retainer 10. A tension spring 9 is provided on the outer side of each of the two guide rods 11. The two ends of the tension spring 9 are respectively connected to the outer wall of the retainer 10 and the abutment bar 2 on the side that are close to each other. The retainer 10 is movably locked onto the outer side of the connecting block 7.

[0029] The guide rod 11 allows the card holder 10 to slide easily. Under the tension of the tension spring 9, one side of the card holder 10 always moves closer to the abutment bar 2. When the connecting block 7 abuts against the outside of the abutment bar 2, the card holder 10 automatically presses down and locks the connecting block 7 under the rebound of the tension spring 9, thereby fixing the fixing frame 3.

[0030] Multiple contact components include a smoke sensor 15 fixedly installed on the outer wall of one side of the temperature alarm 6, a sensing head 14 fixedly installed on one side of the smoke sensor 15, and a connecting seat 12 fixedly fitted on the outside of the smoke sensor 15.

[0031] Both the smoke sensor 15 and the temperature alarm 6 are existing technologies. The temperature sensor 6 is used in conjunction with a buzzer. It should be noted that the sensor head 14 can detect smoke at close range, thereby activating the self-protection components and providing early warning and protection.

[0032] The self-protection component includes a nozzle 16 connected to and installed inside one end of a connecting pipe 19. An arc-shaped pipe 4 is connected to one side of the nozzle 16. A seal is provided on the inner side of one end of the arc-shaped pipe 4. The seal includes a sealing plug 5. The sealing plug 5 is movably locked inside one end of the arc-shaped pipe 4. The sealing plug 5 can be removed and filled with dry powder. The nozzle 16 and the arc-shaped pipe 4 are connected, which facilitates the spraying of dry powder.

[0033] The arc-shaped tube 4 has a cavity 20 inside. The nozzle 16 has a spraying component inside one side. The spraying component includes multiple sets of nozzles 17. The multiple sets of nozzles 17 are arranged at equal distances along the arc-shaped trajectory inside the nozzle 16. Both ends of the slide 23 are threaded with pins 22, and the ends of the corresponding pins 22 abut against the outer side of the connecting seat 12.

[0034] The cavity 20 can be filled with dry powder. With the connection of the booster air pump 18, the dry powder can be sprayed outward through the nozzle 17 to spray the dry powder onto the stripped connection of the cable, thereby reducing the possibility of fire from the fire source. The slide 23 can be limited by the set screw 22 to meet the use of cables with different stripping lengths, and to make the components such as the arc tube 4 and the nozzle 16 converge at the stripped part of the cable for use.

[0035] It should be noted that components such as connecting pipe 19, arc pipe 4, and nozzle 16 all use rigid tubing.

[0036] Working principle: In use, first install the fixing bracket 3. The user first pulls the card holder 10 upward from the outside of the abutment bar 2, then slides the connecting block 7 inside the mounting base 8 to the outside of the abutment bar 2. At this time, release the card holder 10, and the card holder 10 will return to its original position under the contraction of the tension spring 9, causing the card holder 10 to press against the outside of the connecting block 7, thus fixing it. This method of installation and disassembly is relatively convenient. After the fixing bracket 3 is installed, the self-protection component is set on the outside of the cable. According to the stripping height of the cable, adjust the corresponding slide 23 so that the slide 23 can drive the arc When components such as the curved tube 4 are near the stripped part of the cable, the temperature alarm 6 will automatically sound an alarm when the temperature at the connection between the cable and the relay 1 is too high. If the staff has not arrived yet, the situation will worsen. When the sensor head 14 detects the smoke of spontaneous combustion, the smoke sensor 15 will cause the booster pump 18 below to work. Through the connection pipe 19, high-pressure gas will be delivered to the inside of the curved tubes 4 and the nozzle 16 at both ends. The multiple sets of nozzles 17 arranged in this arc shape can spray the pre-filled dry powder onto the cable connection, reduce the probability of fire, and provide timely fire source warning.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
