Description

Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, specifically a high voltage switchgear with monitoring function. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for switching, control, or protection in power generation, transmission, distribution, energy conversion, and consumption. High-voltage switchgear is categorized by voltage level from 3.6kV to 550kV, including high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and disconnectors, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear itself.

Cleaning structures are fixedly installed on one end of each side of the cabinet. This utility model discloses a high-voltage switchgear with monitoring function. The high-voltage switchgear uses temperature and humidity sensors to monitor the internal temperature and humidity of the switchgear. A fan is powered on to release airflow, accelerating the flow of air inside the switchgear for heat dissipation or dehumidification. Two motors drive two screws to rotate, which in turn move two cleaning brushes up and down to clean the first and second ventilation holes, preventing blockage and ensuring proper ventilation and heat dissipation of the high-voltage switchgear.

The air intake and exhaust areas of the device cannot be adjusted, which will limit the heat dissipation capacity of the switch cabinet and pose a risk of not being able to effectively cool down under high temperature conditions.

A first electric push rod is fixed on the surface of the first support plate. A first baffle is fixed at one end of the first electric push rod.

[0008] Preferably, the air outlet adjustment mechanism includes a second support plate, which is fixed to the upper right side of the surface of the high-voltage switchgear body. A second electric push rod is fixed to the surface of the second support plate, and a second baffle is fixed to one end of the second electric push rod. An air outlet is provided on the upper right side of the surface of the high-voltage switchgear body, and a second filter screen is fixed to the inner wall of the air outlet. A first exhaust fan is fixed to the upper right side of the inner wall of the high-voltage switchgear body.

[0009] Preferably, a first guide rod is slidably passed through the surface of the first support plate, and one end of the first guide rod is fixedly connected to the surface of the first baffle. A second guide rod is slidably passed through the surface of the second support plate, and one end of the second guide rod is fixedly connected to the surface of the second baffle.

[0010] Preferably, the auxiliary ventilation mechanism includes two extension plates, which are fixedly connected to the front and rear sides of the upper part of the inner wall of the high-voltage switchgear body. A second exhaust fan is fixed to the opposite side of the two extension plates. A top exhaust vent is opened on the top of the high-voltage switchgear body. A first grille plate is fixed to the inner wall of the top exhaust vent. A third filter is fixed to the bottom of the first grille plate. A third electric push rod is fixed to the top of the high-voltage switchgear body. A second grille plate is fixed to one end of the third electric push rod. A temperature sensor is fixed to the upper part of the inner wall of the high-voltage switchgear body.

[0011] Preferably, the top of the high-voltage switchgear body has two L-shaped plates that are arranged opposite each other, and the second grid plate is slidably connected to the surface of the L-shaped plate.

[0012] Preferably, the cleaning mechanism includes two mounted bearings, which are fixedly connected to the lower left side of the high-voltage switchgear body surface. A motor is fixed to the lower left side of the high-voltage switchgear body surface, and a reciprocating lead screw is fixed to the output shaft of the motor. The reciprocating lead screw is installed on the inner wall of the mounted bearings, and a threaded sleeve is threaded onto the surface of the reciprocating lead screw.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model improves the environmental adaptability of the device's heat dissipation through the coordinated design of the air inlet adjustment mechanism, the air outlet adjustment mechanism, and the auxiliary exhaust mechanism. By dynamically adjusting the area of ​​the air inlet and outlet, it can match the heat dissipation requirements under different loads and ambient temperatures, avoiding the efficiency bottleneck of fixed air outlets. Under high temperature or high load conditions, the opening is maximized and the bidirectional fan and the first exhaust fan are activated to form high-speed convection heat dissipation. The second exhaust fan and the third electric push rod work together to allow the heat at the top to be quickly discharged. Under low load or low temperature conditions, the opening is reduced to reduce the risk of condensation inside the cabinet caused by excessive intake of cold air.

[0016] Secondly, this utility model makes the first filter screen less prone to clogging through the automated cleaning mechanism. The reciprocating motion of the brush plate covers the entire surface of the first filter screen, periodically removing the attached dust and preventing the reduction of air intake due to filter screen clogging. At the same time, the sliding connection design between the T-shaped plate and the mounting shell allows for quick replacement of worn brushes, significantly reducing maintenance costs.

Controller. Detailed Implementation

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-7 A high-voltage switchgear with monitoring function includes a high-voltage switchgear body 1, an air inlet regulating mechanism 2 and a cleaning mechanism 5 on the left side of the high-voltage switchgear body 1, an air outlet regulating mechanism 3 on the right side of the high-voltage switchgear body 1, and an auxiliary exhaust mechanism 4 on the top of the high-voltage switchgear body 1.

[0027] The air intake adjustment mechanism 2 includes two first support plates 201. The first support plates 201 are fixedly connected to the lower left side of the inner wall of the high voltage switchgear body 1. A first electric push rod 203 is fixed on the surface of the first support plate 201. A first baffle 204 is fixed at one end of the first electric push rod 203. A bidirectional fan 202 is fixed between the two first support plates 201. An air inlet is provided on the lower left side of the surface of the high voltage switchgear body 1. A first filter screen 205 is fixed on the inner wall of the air inlet. A dust sensor 207 is fixed on the lower left side of the inner wall of the high voltage switchgear body 1. A controller 6 is fixed on the surface of the high voltage switchgear body 1.

[0028] Through the above technical solution, the first electric push rod 203 can drive the first baffle 204 to move laterally. The symmetrical movement of the two first baffles 204 can adjust the opening and closing area of ​​the air inlet. By dynamically adjusting the air inlet area, it can adapt to the heat dissipation requirements under different working conditions and avoid the heat dissipation bottleneck caused by insufficient cold air intake. The bidirectional fan 202 selects the internal suction or external exhaust mode according to the dust sensor 207 data received by the controller 6. When the dust content is high, the cleaning mechanism 5 cleans the first filter 205 and, together with the bidirectional fan 202, exhausts the dust to blow out of the high-voltage switchgear body 1, preventing the fine dust crushed during the cleaning process from entering the interior of the high-voltage switchgear body 1.

[0029] The air outlet regulating mechanism 3 includes a second support plate 301, which is fixed to the upper right side of the surface of the high voltage switchgear body 1. A second electric push rod 302 is fixed to the surface of the second support plate 301. A second baffle 303 is fixed to one end of the second electric push rod 302. An air outlet is opened on the upper right side of the surface of the high voltage switchgear body 1. A second filter screen 304 is fixed to the inner wall of the air outlet. A first exhaust fan 305 is fixed to the upper right side of the inner wall of the high voltage switchgear body 1.

[0030] Through the above technical solution, the air outlet adjustment mechanism 3 pushes the second baffle 303 to slide through the second electric push rod 302 to control the air outlet area. The first exhaust fan 305 works with the second filter 304 to accelerate the exhaust of hot air. The controller 6 adjusts the opening of the second baffle 303 according to the linkage of the temperature sensing component in the auxiliary exhaust mechanism 4 to achieve a dynamic balance between the air outlet volume and the air inlet volume.

[0031] A first guide rod 206 slides through the surface of the first support plate 201, and one end of the first guide rod 206 is fixedly connected to the surface of the first baffle 204. A second guide rod 306 slides through the surface of the second support plate 301, and one end of the second guide rod 306 is fixedly connected to the surface of the second baffle 303.

[0032] Through the above technical solution, the first guide rod 206 and the second guide rod 306 can provide linear guidance for the movement of the first baffle 204 and the second baffle 303, and constrain the offset of the first electric push rod 203 and the second electric push rod 302 when driven.

[0033] The auxiliary ventilation mechanism 4 includes two extension plates 401, which are fixedly connected to the front and rear sides of the upper inner wall of the high voltage switchgear body 1. A second exhaust fan 402 is fixed to the opposite side of the two extension plates 401. A top exhaust port is opened on the top of the high voltage switchgear body 1. A first grille plate 404 is fixed to the inner wall of the top exhaust port. A third filter 403 is fixed to the bottom of the first grille plate 404. A third electric push rod 405 is fixed to the top of the high voltage switchgear body 1. A second grille plate 406 is fixed to one end of the third electric push rod 405. A temperature sensor 408 is fixed to the upper inner wall of the high voltage switchgear body 1.

[0034] Through the above technical solution, the second exhaust fan 402 can draw hot air from the top of the high-voltage switchgear body 1, and discharge it through the top exhaust port after passing through the third filter 403. This can form a vertical airflow path, eliminate heat accumulation in the upper part of the cabinet, and improve the heat dissipation efficiency of the device. The third electric push rod 405 drives the second grille plate 406 to slide, which, together with the first grille plate 404, can adjust the opening and closing degree of the top exhaust port. Thus, when exhaust is not required, the second grille plate 406 can form a closed effect with the first grille plate 404, making it difficult for dust to fall onto the surface of the third filter 403. The temperature sensor 408 monitors the temperature inside the cabinet in real time and triggers the third electric push rod 405 and the second exhaust fan 402 to operate.

[0035] Two L-shaped plates 407 are fixed on the top of the high-voltage switchgear body 1, and the second grid plate 406 is slidably connected to the surface of the L-shaped plate 407.

[0036] Through the above technical solution, the L-shaped plate 407 provides precise guidance, ensuring that the second grid plate 406 moves in a straight line.

[0037] The cleaning mechanism 5 includes two mounted bearings 501, which are fixedly connected to the lower left side of the surface of the high-voltage switchgear body 1. A motor 502 is fixedly mounted on the lower left side of the surface of the high-voltage switchgear body 1. A reciprocating lead screw 503 is fixed to the output shaft of the motor 502. The reciprocating lead screw 503 is installed on the inner wall of the mounted bearings 501. A threaded sleeve 504 is threadedly connected to the surface of the reciprocating lead screw 503. A mounting shell 505 is fixed to the surface of the threaded sleeve 504. Two guide frames 507 are fixedly mounted on the lower left side of the surface of the high-voltage switchgear body 1. The mounting shell 505 is slidably connected to the surface of the guide frame 507. A brush plate 506 is detachably connected to the surface of the mounting shell 505.

[0038] Through the above technical solution, the motor 502 drives the reciprocating screw 503 to rotate, and the screw sleeve 504 drives the mounting shell 505 and the brush plate 506 to reciprocate linearly along the guide frame 507 under the action of the thread on the surface of the reciprocating screw 503, so as to achieve contact cleaning with the surface of the first filter screen 205.

[0039] A T-shaped plate 508 is fixed to the surface of the brush plate 506. The T-shaped plate 508 is slidably connected to the inner wall of the mounting shell 505. The front and rear sides of the inner wall of the mounting shell 505 are open structures.

[0040] Through the above technical solution, the sliding design of the T-shaped plate 508 allows for quick disassembly and assembly of the brush plate 506. During disassembly, it can be pulled out directly along the open front and rear sides to meet the replacement needs of different wear levels.

[0041] The controller 6 is electrically connected to the first electric push rod 203, the bidirectional fan 202, the dust sensor 207, the second electric push rod 302, the first exhaust fan 305, the temperature sensor 408, the second exhaust fan 402, the third electric push rod 405, and the motor 502.

[0042] Working principle: The high-voltage switchgear body 1 can be driven by the first electric push rod 203 to move the first baffle 204 laterally. Through the symmetrical movement of the two first baffles 204, the opening area of ​​the air inlet can be adjusted. The opening of the first baffle 204 is increased to introduce more cold air. At the same time, the second electric push rod 302 can also adjust the air outlet area by moving the second baffle 303 to form a dynamic balance with the air volume. The second exhaust fan 402 can draw hot air from the top. The third electric push rod 405 adjusts the opening of the second grille 406 according to the data of the temperature sensor 408 to form a top heat dissipation path and further improve the heat dissipation effect of the device. When it is necessary to clean the first filter 205, the bidirectional fan 202 reverses to exhaust air to the air inlet. The motor 502 drives the reciprocating screw 503 to drive the brush plate 506 to periodically clean the first filter 205. With the bidirectional fan 202, the cleaned dust is automatically blown out of the high-voltage switchgear body 1, ensuring that the air inlet of the high-voltage switchgear body 1 is not blocked by dust.

[0043] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
