Description

Technical Field

[0001] The invention relates to the technical field of arc protectors, in particular to an arc protector with electromagnetic interference protection. Background Art

[0002] Arc protector is a protective device used in electrical systems, specially designed to detect and interrupt arc faults. Arc is a high temperature phenomenon caused by electric arc, which can cause fire risk to electrical equipment and electrical lines. Arc protector determines whether arc occurs by monitoring abnormal changes in current waveform, and then quickly cuts off the circuit to prevent fire.

[0003] For example, the publication number CN213151631U states that "an arc protector with electromagnetic interference protection" includes an arc protector body, an arc detector, an information processor and copper plate ventilation holes. A plastic shell is fixedly installed on the outer surface of the arc protector body, a first magnetic shielding plate is sleeved on the inner wall of the plastic shell, a metal fine mesh is sleeved on the inner wall of the first magnetic shielding plate, a heat dissipation hole is provided on one side of the plastic shell, a light shield is sleeved on the inner wall of the metal fine mesh, a circuit element is fixedly installed on the inner wall of the top of the light shield, a filter is fixedly installed on the bottom of the circuit element, an arc detector is fixedly installed on the bottom of the filter, a copper wire is fixedly connected to the bottom of the information processor, a power-off system is fixedly installed on the inner wall of the heat-dissipating copper plate, and a battery is fixedly installed on the left side of the power-off system. The arc protector with electromagnetic interference protection has good heat dissipation and the advantages of electromagnetic interference protection, a simple structure, and improves the normal operation rate of the equipment.

[0004] However, in the prior art, although this type of arc protector has the advantages of good heat dissipation performance and prevention of electromagnetic interference, it is lacking in the inspection and maintenance of the internal components of the arc protector and the replacement of the anti-magnetic plate. Since this type of arc protector does not have a structure for assisting the disassembly and assembly of the electrical components and the anti-magnetic plate inside the protector, when the electrical components inside the protector need to be maintained and inspected, the staff needs to use disassembly tools to disassemble and assemble them. The disassembly and assembly will not only reduce the maintenance efficiency of the arc protector, but also, since this type of protector cannot replace the anti-magnetic plate, as the use time increases, the anti-magnetic plate may be worn or aged due to environmental factors such as high temperature, humidity, etc. or mechanical damage such as collision, extrusion, resulting in a decrease in its shielding performance, which in turn causes the arc protector to be affected by external electromagnetic noise and affect the performance of the arc protector, resulting in malfunction or faulty operation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the silent motor drives the gear A to rotate, and the gear A drives the gear B to rotate through the tooth chain, thereby driving the rotating rod A and the screw rod to rotate. When the screw rod rotates, it drives the limit plate to slide on the surface of the limit rod A, thereby driving the limit block to move upward inside the protector shell through the roller, and when the limit block moves upward, it drives the push plate to move upward, so that the protective box rises from the inside of the protector shell. At this time, the anti-magnetic plate can be disassembled and replaced. When the arc protector body needs to be maintained, only the cover plate needs to be rotated. After the cover plate is turned open, the arc protector inside the protective box can be maintained, thereby avoiding the need to use disassembly and assembly tools to disassemble and assemble the arc protector when maintaining it.

[0018] 2. In the present invention, the heat of the arc protector is introduced into the push plate through the heat conductive block, and the push plate then introduces the heat into the heat fins through the heat conductive frame. At this time, the silent fan can be turned on, and the silent fan will blow out the heat on the heat fins, and the air outside the protector shell will enter the interior of the protector shell through the air inlet, thereby dissipating the heat of the heat fins. When the air enters the interior of the protector shell, it will first be filtered by the filter plate, thereby preventing dust from adhering to the heat dissipation fins and causing the heat dissipation efficiency of the heat dissipation fins to decrease. When the filter plate needs to be cleaned or replaced, it is only necessary to rotate the card block. When the card block is rotated to the bottom of the fixing rod B, the fixing rod B is slid. After the fixing rod B moves to the top of the card block, the card block can be released. At this time, the filter plate can be taken out from the inside of the protector shell through the fixing plate, thereby facilitating the staff to clean and maintain the filter plate.

[0019] 3. In the present invention, by moving the shift block, the shift block will slide on the surface of the protrusion and drive the insertion rod to slide. After the insertion rod slides out from the inside of the baffle, the baffle will be rotated by the torsion force of the torsion spring C. After the baffle is turned open, the control panel can be operated. After the operation is completed, the cover plate is rotated again. After the cover plate covers the surface of the control panel, the shift block can be released. At this time, the insertion rod will be affected by the elastic force of the spring and slide inside the protrusion. After the insertion rod is inserted into the inside of the baffle, the baffle can be fixed. The easy-to-open design of the baffle not only facilitates the staff to operate the control panel, but also prevents the staff from accidentally touching the arc protector body and causing unnecessary losses.

[0036] The silent motor 101 drives the gear A102 to rotate, and the gear A102 drives the gear B103 to rotate through the toothed chain 104, thereby driving the rotating rod A105 and the screw rod 106 to rotate, and the screw rod 106 will drive the limit plate 110 to slide on the surface of the limit rod A111 when rotating, thereby driving the limit block 108 to move upward inside the protector housing 100 through the roller 109, and the limit block 108 will drive the push plate 107 to move upward when moving upward, so that the protection box 115 rises from the inside of the protector housing 100, and the anti-magnetic plate 120 can be disassembled and replaced at this time, and when the arc protector body 116 needs to be maintained, only the cover plate 123 needs to be rotated, and the arc protector inside the protection box 115 can be maintained after the cover plate 123 is turned away, thereby avoiding the need to use disassembly tools to disassemble and assemble the arc protector when maintaining it;

The clamping block 208 is slidably connected to the protector housing 100, and the fixing plate 205 is slidably connected to the protector housing 100.

[0039] In this embodiment, the heat of the arc protector is introduced into the push plate 107 through the heat conductive block 201, and then the push plate 107 introduces the heat into the heat dissipation fins 204 through the heat conductive frame 203. At this time, the silent fan 213 can be turned on, and the silent fan 213 will blow out the heat on the heat dissipation fins 204, and the air outside the protector housing 100 will enter the inside of the protector housing 100 through the air inlet 200, so as to dissipate the heat of the heat dissipation fins 204. When the air enters the inside of the protector housing 100, it will first be filtered by the filter plate 206, so as to prevent To prevent dust from adhering to the heat dissipation fins 204 and causing the heat dissipation efficiency of the heat dissipation fins 204 to decrease, when the filter plate 206 needs to be cleaned or replaced, the block 208 only needs to be rotated, and when the block 208 is rotated to the bottom of the fixing rod B211, the fixing rod B211 is slid, and when the fixing rod B211 moves to the top of the block 208, the block 208 can be released, and the filter plate 206 can be taken out from the inside of the protector housing 100 through the fixing plate 205, thereby facilitating the cleaning and maintenance of the filter plate 206 by the staff;

When the block 208 rotates to the interior of the protector housing 100, the installation of the fixing plate 205 and the filter plate 206 can be completed.

[0041] Embodiment 3: According to Figure 11-12 As shown, a control panel 300 is fixedly mounted on the surface of the protector housing 100, a rotating rod D301 is rotatably connected inside the control panel 300, a torsion spring C309 is sleeved on the surface of the rotating rod D301, a baffle 302 is fixedly mounted on one end of the rotating rod D301, an observation plate 303 is fixedly mounted inside the baffle 302, a protrusion 304 is fixedly mounted on the surface of the control panel 300, a sliding rod 305 is slidably connected inside the protrusion 304, a spring 306 is sleeved on the surface of the sliding rod 305, and an insertion rod 307 is fixedly mounted on one end of the sliding rod 305. A shift block 308 is fixedly installed on the surface of the plug rod 307, one end of the torsion spring C309 is connected to the side of the baffle 302, and the other end is connected to the inner surface of the control board 300, the observation board 303 is made of tempered glass, the baffle 302 and the protrusion 304 are slidingly connected, one end of the spring 306 is connected to the surface of the plug rod 307, and the other end is connected to the inner surface of the control board 300, the plug rod 307 and the protrusion 304 are slidingly connected, the plug rod 307 and the baffle 302 are slidingly connected, and the shift block 308 and the protrusion 304 are slidingly connected.

[0042] After the cover 123 covers the surface of the control panel 300, the block 308 can be released. At this time, the rod 307 can be slid inside the protrusion 304 by the elastic force of the spring 306. After the rod 307 is inserted into the inside of the baffle 302, the baffle 302 can be fixed. The easy-to-open design of the baffle 302 not only facilitates the operation of the control panel 300 by the staff, but also prevents the staff from accidentally touching the arc protector body 116 and causing unnecessary losses.

[0043] The use method and working principle of the device: When the protector housing 100 needs to be disassembled, the fixing block 114 only needs to be rotated. After the fixing block 114 is rotated away from the surface of the fixing rod A112, the top plate 113 can be pulled out from the surface of the fixing rod A112. After the top plate 113 is pulled out, the protector housing 100 can be disassembled;

[0044] When the arc protector body 116 needs to be maintained and repaired, it is only necessary to turn on the silent motor 101, which will drive the gear A102 to rotate, and the gear A102 will drive the gear B103 to rotate through the toothed chain 104, thereby driving the rotating rod A105 and the screw rod 106 to rotate, and the screw rod 106 will drive the limit plate 110 to slide on the surface of the limit rod A111 when rotating, thereby driving the limit block 108 to move upward inside the protector housing 100 through the roller 109. When the limit block 108 moves upward, it will drive the push plate 107 to move upward, so that the protection box 115 rises from the inside of the protector housing 100. At this time, the anti-magnetic plate 120 can be disassembled and replaced. When the arc protector body 116 needs to be maintained, only the cover plate 123 needs to be rotated. After the cover plate 123 is turned away, the arc protector inside the protection box 115 can be maintained, thereby avoiding the need to use a disassembly tool to disassemble and assemble the arc protector when maintaining it.

[0045] When the cover plate 123 needs to be closed, the torsion spring A122 is used to drive the rotating rod B121 to rotate, thereby driving the cover plate 123 to rotate. After the limit groove A124 on the cover plate 123 rotates to the limit rod B118, the protection box can be closed, so that the maintenance personnel can close the protection box 115 after maintaining the arc protector body 116.

[0046] When the arc protector body 116 needs to be cooled, the heat of the arc protector only needs to be introduced into the push plate 107 through the heat conducting block 201, and then the push plate 107 introduces the heat into the heat dissipation fins 204 through the heat conducting frame 203. At this time, the silent fan 213 can be turned on, and the silent fan 213 will blow out the heat on the heat dissipation fins 204, and the air outside the protector housing 100 will enter the inside of the protector housing 100 through the air inlet 200, so as to cool the heat dissipation fins 204. When the air enters the inside of the protector housing 100, it will first pass through the filter plate 20 6, thereby preventing dust from adhering to the heat dissipation fins 204 and causing the heat dissipation efficiency of the heat dissipation fins 204 to decrease. When the filter plate 206 needs to be cleaned or replaced, the block 208 only needs to be rotated. When the block 208 is rotated to the bottom of the fixing rod B211, the fixing rod B211 is slid. When the fixing rod B211 moves to the top of the block 208, the block 208 can be released. At this time, the filter plate 206 can be taken out from the inside of the protector housing 100 through the fixing plate 205, thereby facilitating the cleaning and maintenance of the filter plate 206 by the staff.

[0047] When the filter plate 206 needs to be installed, the fixing plate 205 only needs to be inserted into the inside of the protector, and then the fixing rod B211 is slid. After the fixing plate 205B is away from the clamping block 208, the clamping block 208 will rotate due to the torsion force of the torsion spring B209. After the clamping block 208 rotates to the inside of the protector housing 100, the installation of the fixing plate 205 and the filter plate 206 can be completed.

[0048] When it is necessary to control and adjust the control panel 300, it is only necessary to first move the dial block 308. The dial block 308 will slide on the surface of the protrusion 304 and will also drive the insertion rod 307 to slide. After the insertion rod 307 slides out from the inside of the baffle 302, the baffle 302 will rotate due to the torsion force of the torsion spring C309. After the baffle 302 is turned away, the control panel 300 can be operated. After the operation is completed, the cover plate 123 is rotated again. After the cover plate 123 covers the surface of the control panel 300, the dial block 308 can be released. At this time, the insertion rod 307 will slide inside the protrusion 304 due to the elastic force of the spring 306. After the insertion rod 307 is inserted into the inside of the baffle 302, the baffle 302 can be fixed. The easy-to-switch design of the baffle 302 not only facilitates the staff to operate the control panel 300, but also prevents the staff from accidentally touching the arc protector body 116 and causing unnecessary losses.
