Description

Technical Field

[0001] The invention relates to the technical field of high-voltage vacuum circuit breakers, and in particular to a circuit breaker with exhaust and cooling functions. Background Art

[0002] When the circuit breaker works for a long time or carries a large current, a large amount of heat will be generated inside it due to the passage of current. If this heat cannot be dissipated in time, the temperature of the circuit breaker will rise, which will affect its electrical and mechanical properties. Specifically, high temperature may accelerate the aging of the insulating material inside the circuit breaker and reduce its insulation strength; at the same time, high temperature will also increase the resistance of the contacts, causing increased contact wear and shortening the service life of the circuit breaker. In the prior art, when using ventilation and exhaust to cool the circuit breaker inside the electrical cabinet, if the surrounding ambient temperature is also very high, the efficiency of cooling the circuit breaker will be greatly reduced, and even spontaneous combustion may occur. At the same time, when ventilating and exhausting, if the filter is not cleaned for a long time, the filter will be blocked by dust, and ventilation cannot be achieved normally. Therefore, in order to solve the above problems, we provide a circuit breaker with exhaust and cooling function. Summary of the invention

[0003] The present invention aims to solve the technical problem of how, when dissipating heat for a circuit breaker inside an electrical cabinet, the device can spray liquid around the electrical cabinet after the temperature reaches a certain level, thereby quickly cooling it down, and the filter can also be flipped while spraying water, so as to remove dust accumulated on the filter, avoid clogging the filter, and reduce the heat dissipation effect of the circuit breaker. A circuit breaker with exhaust and cooling function is provided.

[0094] The reciprocating screw 66 is vertically arranged at the bottom of the water wheel box 61, and its axis coincides with the axis of the water wheel box 61.

The other end passes through the bottom of the water wheel box 61 and extends to the bottom of the water wheel box 61. The reciprocating thread of the reciprocating screw 66 is located below the water wheel box 61.

[0095] The impeller is sleeved on the reciprocating screw 66 and is located inside the water wheel box 61. The impeller is fixedly connected to the side of the reciprocating screw 66, and the blade shape of the impeller is arc-shaped.

[0096] The limit plate 67 is laterally arranged on the outer side of the cabinet 2 close to the filter screen 37, and is directly below the reciprocating screw 66.

[0097] The movable sleeve 62 is sleeved on the slider of the reciprocating screw 66 and is located on the outer side of the cabinet 2 close to the reciprocating screw 66. The side of the movable sleeve 62 close to the cabinet 2 is slidingly connected to the side of the cabinet 2 close to the reciprocating screw 66. The sliding direction is vertically arranged and parallel to the axis of the reciprocating screw 66. The movable sleeve 62 is connected to the slider of the reciprocating screw 66. The side of the movable sleeve 62 close to the filter screen 37 is fixedly connected to a plurality of sprayers 52 respectively.

[0098] The gear 64 is sleeved on one of the connecting rods 65 that passes through the side of the cabinet 2 and is located on the outer side of the cabinet 2 . The gear 64 is fixedly connected to the side of the connecting rod 65 that passes through the side of the cabinet 2 .

[0099] The rack 63 is arranged on the side of the movable sleeve 62 close to the cabinet 2 and is located outside the cabinet 2 close to the gear 64. The plane of the rack 63 is fixedly connected to the side of the movable sleeve 62 close to the cabinet 2, and the tooth surface is meshed with the gear 64.

[0100] The water wheel box 61, the impeller, the movable sleeve 62, the rack 63, the gear 64, the two connecting rods 65, the reciprocating screw 66, and the limit plate 67 are arranged. The reciprocating screw 66 can drive the movable sleeve 62 to rotate, so that the rack 63 can drive the gear 64 to rotate, and then the filter 37 can be turned over, so that the side of the filter 37 close to the plurality of blades 32 is rotated to be close to the outside, so that the dust adhering to the filter is blown away by the blowing of the plurality of blades 32.

[0101] A temperature detector is also provided inside the cabinet 2 , and the temperature detector is electrically connected to the controller 1 .

[0102] By providing a temperature detector, the temperature inside the cabinet 2 can be accurately determined through the controller 1 to avoid danger caused by excessive temperature.

[0103] The side surface of the cabinet 2 close to the reciprocating screw 66 is set to be a smooth surface and is made of insulating material.

[0104] The side surface of the cabinet 2 close to the reciprocating screw 66 is set to a smooth surface and is made of insulating material, which can effectively prevent the liquid sprayed by the sprayers 52 from entering the interior of the cabinet 2 or causing damage to other components due to conduction.

[0105] Working process: When the user wants to exhaust and cool the circuit breaker inside the cabinet 2, the user can start the drive motor 31 through the controller 1. After the drive motor 31 is started, the drive motor 31 drives the plurality of fan blades 32 and the electromagnetic block 48 to rotate. The rotation of the plurality of fan blades 32 can draw the outside air into the cabinet 2 through the first air inlet 35, and then discharge the air inside the cabinet 2 to the outside of the cabinet 2 through the second air inlet 38, the air outlet duct 34, and the filter 37, so as to realize the air replacement inside the cabinet 2, so that the temperature inside the cabinet 2 can be reduced.

[0106] When the driving motor 31 is started, if the temperature inside the cabinet 2 still cannot be reduced, the mercury inside the groove 44 will gradually expand due to the high temperature, and then push the push block 45 up until the control button 51 is pressed down. When the control button 51 is pressed down, the control button 51 will transmit the control signal to the controller 1. After receiving the control signal, the controller 1 will actively control the electromagnetic block 48 to start. After the electromagnetic block 48 is started, the electromagnetic block 48 will release the magnetic force. When the electromagnetic block 48 releases the magnetic force and rotates, and is directly below the magnetic plate 49, the magnetic plate 49 will move upward after sensing the repulsive force of the electromagnetic block 48. The magnetic plate 49 moves upward to shorten the compression spring 50, and the water head inside the piston cylinder 41 is transported to the water wheel box 61 through the second connecting port, the second pipeline, and the second one-way valve.

[0107] When the electromagnetic block 48 rotates and leaves the bottom of the magnetic plate 49, the magnetic plate 49 will stop being repelled by the electromagnetic block 48, the electromagnetic plate will stop rising, and will stop applying pressure to the spring 50. The spring 50 will rebound after stopping being under pressure, and the rebound of the spring 50 will drive the electromagnetic plate to move downward. When the electromagnetic plate moves downward, the water inside the water tank 42 will enter the piston cylinder 41 through the first pipe, the first connecting port, and the first one-way valve until the electromagnetic plate returns to its original position and the water inside the piston cylinder 41 is filled.

[0108] When water enters the water wheel box 61, the water inside the water wheel box 61 will impact the arc blades of the impeller, thereby driving the impeller to rotate, and enter the plurality of sprayers 52 through the third pipe, and the plurality of sprayers 52 will spray water to the side of the cabinet 2 and the side of the filter 37, so as to quickly cool the cabinet 2. Since the circuit breaker device 7 inside the cabinet 2 needs to be checked by the user at regular intervals, dust will enter the cabinet 2 after opening it, and when the plurality of blades 32 rotate, the dust inside the cabinet 2 will follow the air to leave the filter 37, but some dust will remain on the side of the filter 37 close to the plurality of blades 32, and at the same time, the side of the filter 37 close to the outside world will also block some dust from the outside world that wants to enter the cabinet 2 when working for a long time, so dust will also accumulate on the side of the filter 37 close to the outside world. At this time, the water sprayed by the plurality of sprayers 52 can also cause the dust on the side of the filter 37 close to the outside to clump due to the water drops, thereby preventing the dust from being hooked on the filter holes of the filter 37, so that the clumped dust can be easily blown away from the surface of the filter 37 by the wind blown by the rotation of the plurality of fan blades 32; When the impeller rotates, the impeller rotates to drive the reciprocating screw 66 to rotate, and the reciprocating screw 66 rotates to drive the movable sleeve 62 to move up and down. When the movable sleeve 62 moves downward, the movable sleeve 62 moves to drive the rack 63 and the plurality of sprayers 52 to move downward until the movable sleeve 62 moves to the end of the reciprocating thread of the reciprocating screw 66, so as to adjust the plurality of sprayers 52 to spray water to the filter 37 and the area on the side of the cabinet 2.

[0109] When the rack 63 moves downward, the rack 63 moves downward and contacts the gear 64, and drives the gear 64 to rotate, the gear 64 rotates and drives the connecting rod 65 connected thereto to rotate, the connecting rod 65 connected to the gear 64 rotates and drives the filter 37 to rotate, the filter 37 rotates and drives another rotating rod to rotate, until the filter 37 is close to the side of the fan blades 32 and is switched to the side away from the fan blades 32, until the rack 63 leaves the gear 64. In this way, the position of the filter 37 relative to the fan blades 32 is adjusted, so that the side of the filter 37 originally close to the fan blades 32 can be rotated to be close to the outside of the cabinet 2, and then the wind blown by the rotation of the fan blades 32 can blow the dust on the side of the filter 37 originally close to the fan blades 32 away from the side of the filter 37, and the filter 37 is cleaned.

[0110] When the movable sleeve 62 moves upward, the movable sleeve 62 drives the rack 63 and the plurality of sprayers 52 to move upward until the movable sleeve 62 returns to its original position, thereby adjusting the plurality of sprayers 52 to spray water onto the filter 37 and the area on the side of the cabinet 2 .

[0111] When the rack 63 moves upward, the rack 63 moves upward and contacts the gear 64, and drives the gear 64 to rotate, the gear 64 rotates and drives the connecting rod 65 connected thereto to rotate, the connecting rod 65 connected to the gear 64 rotates and drives the filter 37 to rotate, the filter 37 rotates and drives another rotating rod to rotate, until the filter 37 is close to the side of the fan blades 32 and is switched to the side away from the fan blades 32, until the rack 63 leaves the gear 64. In this way, the position of the filter 37 relative to the fan blades 32 is adjusted, so that the side of the filter 37 originally close to the fan blades 32 can be rotated to be close to the outside of the cabinet 2, and then the wind blown by the rotation of the fan blades 32 can blow the dust on the side of the filter 37 originally close to the fan blades 32 away from the side of the filter 37, thereby completing the cleaning of the filter 37.

[0112] At the same time, the water sprayed on the side of the filter 37 can also clump the dust, and when the filter 37 is rotated to 90 degrees, the dust clumped on the side of the filter 37 facing the ground will be separated from the side of the filter 37 due to its own gravity, and combined with the thrust exerted by the wind blown by the rotating blades 32, it will leave the air outlet 34. The combination of these two forces can effectively blow the clumped dust away from the side of the filter 37, thereby completing the cleaning of the filter 37.

[0113] When the temperature inside the cabinet 2 drops to a suitable level, the mercury stops expanding and returns to its original volume, the push block 45 moves downward to restore, and stops pressing the control button 51, the controller 1 stops receiving the control signal, and stops controlling the electromagnetic block 48. The cabinet 2 is quickly cooled down. If the angle of the filter 37 does not completely block the air outlet 34 at this time, the user can manually rotate the connecting rod 65 connected to the gear 64 to adjust the angle of the filter 37 so that the filter 37 can completely block the air outlet 34 again.

[0114] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
