Description

Technical Field

[0002] Gas insulated switchgear is a kind of switchgear that encloses the main electrical components such as circuit breakers, disconnectors, grounding switches, transformers, busbars, lightning arresters, etc. in a cabinet filled with insulating gas (mainly sulfur hexafluoride SF 6 ) is a high-voltage electrical device in a metal enclosure. Its basic principle is to use SF 6 The excellent insulation performance of gas is used to achieve insulation isolation between electrical components, allowing the switch cabinet to operate safely and reliably in a high voltage environment.

[0004] In the prior art, although this type of gas-insulated switchgear has the effect of convenient maintenance, it is lacking in controlling the start and stop of the heat dissipation mechanism. Since this type of gas-insulated switchgear does not have the function of adjusting the heat dissipation mechanism according to the temperature inside the switchgear body and the function of intelligently cleaning the filter plate in the heat dissipation mechanism, this will result in this type of gas-insulated switchgear only being able to manually open and close the heat dissipation mechanism of the gas-insulated switchgear and manually clean the filter plate of the heat dissipation mechanism by the staff. This heat dissipation method not only fails to grasp the temperature conditions inside the gas-insulated switchgear in real time and adjust the heat dissipation mechanism in time, but also increases the manpower input of maintenance workers.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the present invention is in use, the temperature condition inside the switch cabinet is monitored in real time through the temperature sensor. When the temperature is higher than the normal temperature and the circuit breaker needs to be cooled, the circuit breaker will transfer the temperature to the surface of the heat sink through the heat conduction block. At this time, the fan will blow the air with a lower temperature outside the outer protective shell to the heat sink, and the filter plate will filter the impurities in the air, so as to prevent dust or other impurities in the air from adhering to the heat sink, resulting in a decrease in the heat dissipation efficiency of the heat sink. At this time, the heat on the surface of the heat sink is discharged from the inside of the outer protective shell through the air outlet, so as to complete the heat dissipation of the circuit breaker. When it is necessary to clean the filter plate, it is only necessary to open the electric push rod A, the electric push rod A will drive the push plate to move, and the push plate will drive the brush plate to clean the filter plate, avoiding the need for workers to clean the filter plate when it is necessary. In the case where the operator manually cleans the filter plate, when the filter plate needs to be replaced, it is only necessary to push the shifting block, and the shifting block will drive the fixed block to slide out of the filter plate. After the fixed block slides out of the filter plate, the filter plate can be pulled out of the slot, and a new filter plate is inserted into the slot. The shifting block is then released, and the shifting block is then acted upon by the elastic force of spring B to drive the fixed block to move upward. After the fixed block is inserted into the filter plate, the filter plate can be replaced. The self-cleaning structure and quick-release structure of the filter plate not only facilitate the cleaning of the filter plate without the need for the operator to use cleaning tools, but also facilitate the operator to replace the filter plate. The design of the temperature sensor also facilitates the operator to monitor the temperature inside the switch cabinet in real time, so as to adjust the switch cabinet in time.

[0019] 2. In the present invention, when in use, the motor A drives the gear A to rotate, and when the gear A rotates, it drives the gear B to rotate through the toothed chain, and the gear B drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the screw rod to rotate on the bottom surface of the observation plate, and also drives the observation plate to slide toward the inside of the switch cabinet, and the observation plate also slides on the surface of the limit rod. After the observation plate slides to the inside of the switch cabinet, the switch cabinet can be opened. When the switch cabinet needs to be closed, it only needs to drive the gear A to reverse through the motor A, so that the observation plate moves upward inside the switch cabinet. At this time, the switch cabinet will drive the sealing strip to move upward, and the switch cabinet can be closed after the sealing strip slides to the inside of the sealing groove A. The movable design of the observation plate not only facilitates the staff to observe the internal situation of the switch cabinet, but also facilitates the opening and closing of the switch cabinet, so as to facilitate the staff to maintain and repair the circuit breaker, and the design of the sealing strip and the sealing groove A also improves the sealing effect of the connection between the observation plate and the switch cabinet.

[0020] 3. When the present invention is in use, the weather is detected by the rain sensor. When the rain sensor detects rain, the electric push rod B will drive the cover plate to move downward, and the cover plate will drive the side curtain to move downward. After the cover plate moves to the top of the outer protective shell, it can prevent rain from entering the inner part of the outer protective shell, thereby avoiding the situation that rainwater invades the inner part of the fan and causes the fan to short-circuit, and also avoids the situation that rainwater invades the inner part of the heat sink and causes the heat sink to be rusted, thereby ensuring that the heat dissipation mechanism of the switch cabinet can operate normally in rainy weather, and the motor B drives the Gear C rotates, and when it rotates, gear C will drive gear D to rotate, and gear D will drive the baffle to rotate. After the baffle is rotated out of the sealing groove B, the air inlet can be opened. At this time, the heat sink can be cooled by the fan. When the heat sink does not need to be cooled, it is only necessary to reverse the gear C through the motor B to drive the baffle to rotate. After the baffle rotates into the sealing groove B, the air inlet can be closed, thereby preventing dust and impurities in the air or raindrops and snowflakes in rainy and snowy weather from adhering to the heat sink, which may cause corrosion of the heat sink.

[0033] In this embodiment, the temperature condition inside the switch cabinet 100 is monitored in real time by the temperature sensor 110. When the temperature is higher than the normal temperature and the circuit breaker 101 needs to be cooled, the circuit breaker 101 will transfer the temperature to the surface of the heat sink 103 through the heat conductive block 102.

After the fixed block 119 slides out of the filter plate 109, the filter plate 109 can be pulled out from the slot 114. At this time, a new filter plate 109 is inserted into the slot 114, and the dial block 118 is released. At this time, the dial block 118 will be affected by the elastic force of the spring B117 and drive the fixed block 119 to move upward.

[0038] In this embodiment, the motor A200 drives the gear A201 to rotate, and the gear A201 drives the gear B203 to rotate through the toothed chain 202, and the gear B203 drives the rotating shaft 204 to rotate.

After the observation plate 205 slides to the inside of the switch cabinet 100, the switch cabinet 100 can be opened;

[0039] The motor A200 drives the gear A201 to reverse, so that the observation plate 205 moves upward inside the switch cabinet 100. At this time, the switch cabinet 100 will drive the sealing strip 206 to move upward. After the sealing strip 206 slides to the inside of the sealing groove A209, the switch cabinet 100 can be closed. The movable design of the observation plate 205 not only makes it convenient for the staff to observe the internal situation of the switch cabinet 100, but also makes it convenient to open and close the switch cabinet 100, thereby facilitating the staff to maintain and repair the circuit breaker 101. The design of the sealing strip 206 and the sealing groove A209 also improves the sealing effect of the connection between the observation plate 205 and the switch cabinet 100.

[0040] Embodiment 3: According to Figure 6 and Figure 8-9 As shown, a rain sensor 300 is fixedly installed on the top surface of the switch cabinet 100, a motor B301 is fixedly installed on the side of the outer protective shell 104, a gear C302 is installed on the output end of the motor B301, a gear D303 is rotatably connected inside the outer protective shell 104, a baffle 304 is fixedly installed on the surface of the gear D303, a sealing groove B305 is opened on the bottom surface of the outer protective shell 104, and an electric push rod B306 is fixedly installed on the surface of the switch cabinet 100 A cover plate 307 is installed at the output end of the electric push rod B306, and a side curtain 308 is fixedly installed on the side of the cover plate 307. The gear C302 is rotatably connected to the outer protective shell 104, the gear C302 and the gear D303 are meshed, the baffle 304 is rotatably connected to the outer protective shell 104, the baffle 304 is slidably connected to the sealing groove B305, the cover plate 307 is slidably connected to the switch cabinet 100, and the top surface of the cover plate 307 is chamfered.

[0041] In this embodiment, the weather is detected by the rain sensor 300. When the rain sensor 300 detects rain, the electric push rod B306 drives the cover plate 307 to move downward, and the cover plate 307 drives the side curtain 308 to move downward. After the cover plate 307 moves to the top of the outer protective shell 104, rainwater can be prevented from entering the inner part of the outer protective shell 104, thereby avoiding the situation that rainwater invades the inner part of the fan 108 and causes the fan 108 to short-circuit, and also avoiding the situation that rainwater penetrates into the heat sink 103 and causes the heat sink 103 to be corroded, thereby ensuring that the heat dissipation mechanism of the switch cabinet 100 can operate normally in rainy weather;

[0042] The motor B301 drives the gear C302 to rotate, and the gear C302 will drive the gear D303 to rotate when rotating, and the gear D303 will drive the baffle 304 to rotate. After the baffle 304 is rotated out of the sealing groove B305, the air inlet can be opened. At this time, the heat sink 103 can be cooled by the fan 108. When the heat sink 103 does not need to be cooled, the gear C302 can be reversed by the motor B301 to drive the baffle 304 to rotate. After the baffle 304 rotates into the sealing groove B305, the air inlet can be closed, thereby preventing dust and impurities in the air or raindrops and snowflakes in rainy and snowy weather from adhering to the heat sink 103, which may cause corrosion of the heat sink 103.

[0043] The use method and working principle of the device: when the switch cabinet 100 needs to be cooled, the temperature condition inside the switch cabinet 100 is first monitored in real time through the temperature sensor 110. When the temperature is higher than the normal temperature and the circuit breaker 101 needs to be cooled, the circuit breaker 101 will transfer the temperature to the surface of the heat sink 103 through the heat conduction block 102. At this time, the fan 108 will blow the air with a lower temperature outside the outer protective shell 104 to the heat sink 103, and the filter plate 109 will filter the impurities in the air, so as to prevent dust or other impurities in the air from adhering to the heat sink 103, resulting in a decrease in the heat dissipation efficiency of the heat sink 103. At this time, the heat on the surface of the heat sink 103 is discharged from the inside of the outer protective shell 104 through the air outlet 120, thereby completing the heat dissipation of the circuit breaker 101;

[0044] When it is necessary to seal the connection between the switch cabinet 100 and the heat conductive block 102, the spring A106 is used to drive the sealing gasket A107 to move downward inside the switch cabinet 100. After the sealing gasket A107 is attached to the heat conductive block 102, the connection between the switch cabinet 100 and the heat conductive block 102 can be sealed, thereby avoiding leakage of the insulating gas inside the switch cabinet 100.

[0045] When the filter plate 109 needs to be cleaned, the electric push rod A111 only needs to be opened, and the electric push rod A111 will drive the push plate 112 to move, and the push plate 112 will drive the brush plate 113 to clean the filter plate 109, thereby avoiding the situation where the staff needs to manually clean the filter plate 109 when the filter plate 109 needs to be cleaned;

[0046] When it is necessary to replace the filter plate 109, it is only necessary to move the shifting block 118, and the shifting block 118 will drive the fixing block 119 to slide out of the filter plate 109. After the fixing block 119 slides out of the filter plate 109, the filter plate 109 can be pulled out from the slot 114. At this time, a new filter plate 109 is inserted into the slot 114, and the shifting block 118 is released. At this time, the shifting block 118 is subjected to the elastic force of the spring B117 and drives the fixing block 119 to move upward. After the fixing block 119 is inserted into the filter plate 109, the replacement of the filter plate 109 can be completed. The design of the self-cleaning structure and the quick-release structure of the filter plate 109 not only facilitates the cleaning of the filter plate 109 without the need for the staff to use cleaning tools to clean it, but also facilitates the staff to replace the filter plate 109. The design of the temperature sensor 110 also facilitates the staff to monitor the temperature inside the switch cabinet 100 in real time, so as to adjust the switch cabinet 100 in time.

[0047] When the circuit breaker 101 inside the switch cabinet 100 needs to be maintained and repaired, the motor A200 only needs to be turned on, and the motor A200 will drive the gear A201 to rotate. When the gear A201 rotates, it will drive the gear B203 to rotate through the toothed chain 202, and the gear B203 will drive the rotating shaft 204 to rotate. When the rotating shaft 204 rotates, it will drive the screw rod 207 to rotate on the bottom surface of the observation plate 205, and at the same time, it will drive the observation plate 205 to slide into the inside of the switch cabinet 100, and the observation plate 205 will also slide on the surface of the limit rod 208. After the observation plate 205 slides to the inside of the switch cabinet 100, the switch cabinet 100 can be opened;

[0048] When the switch cabinet 100 needs to be closed, the motor A200 only needs to drive the gear A201 to reverse, so that the observation plate 205 moves upward inside the switch cabinet 100. At this time, the switch cabinet 100 will drive the sealing strip 206 to move upward. After the sealing strip 206 slides to the inside of the sealing groove A209, the switch cabinet 100 can be closed. The movable design of the observation plate 205 not only facilitates the staff to observe the internal situation of the switch cabinet 100, but also facilitates the opening and closing of the switch cabinet 100, so as to facilitate the staff to maintain and repair the circuit breaker 101. The design of the sealing strip 206 and the sealing groove A209 also improves the sealing effect of the connection between the observation plate 205 and the switch cabinet 100.

[0049] When the outer protective shell 104 needs to be closed, the weather needs to be detected by the rain sensor 300. When the rain sensor 300 detects rain, the electric push rod B306 will drive the cover plate 307 to move downward, and the cover plate 307 will drive the side curtain 308 to move downward. After the cover plate 307 moves to the top of the outer protective shell 104, rainwater can be prevented from entering the inner part of the outer protective shell 104, thereby avoiding rainwater from invading the inner part of the fan 108 and causing the fan 108 to short-circuit, and also avoiding rainwater from seeping into the inner part of the heat sink 103 and causing the heat sink 103 to be rusted, thereby ensuring that the heat dissipation mechanism of the switch cabinet 100 can operate normally in rainy weather;

[0050] When the air outlet 120 needs to be closed, it is only necessary to turn on the motor B301, and the motor B301 will drive the gear C302 to rotate. The gear C302 will drive the gear D303 to rotate when rotating, and the gear D303 will drive the baffle 304 to rotate. After the baffle 304 is rotated out of the sealing groove B305, the air inlet can be opened. At this time, the heat sink 103 can be cooled by the fan 108. When the heat sink 103 does not need to be cooled, it is only necessary to reverse the gear C302 through the motor B301, thereby driving the baffle 304 to rotate. After the baffle 304 rotates into the sealing groove B305, the air inlet can be closed, thereby preventing dust and impurities in the air or raindrops and snowflakes in rainy and snowy weather from adhering to the heat sink 103, which may cause corrosion of the heat sink 103.
