Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, and in particular to a pole-mounted circuit breaker that is easy to maintain. Background Technology

[0002] Pole-mounted circuit breakers are circuit breakers installed and operated on utility poles. Significant progress has been made in the research and manufacturing technology of various circuit breakers. Vacuum circuit breakers are no longer limited to medium-voltage power grids but are developing towards high voltage and large capacity. Sulfur hexafluoride circuit breakers have many advantages, such as strong breaking capacity, high continuous breaking capacity, frequent operation, low operating noise, and no fire hazard, making them an excellent oil-free device.

[0003] As shown in the reference case "A primary and secondary integrated pole-mounted circuit breaker that is easy to maintain" (publication number CN219123163U), the circuit breaker is placed in the middle of the top wall of the base. Then, the handle is pulled to move the limiting block out of the fixing groove. The fixing blocks on both sides of the bottom wall of the protective shell are then inserted into the fixing groove. The limiting block is then passed through the fixing block to limit and fix the fixing block, thereby facilitating the installation and disassembly of the protective shell. The protective shell protects the internal circuit breaker, thereby increasing its service life. The knob drives the gear inside the convex plate to rotate. The rotation of the gear drives the rack meshed on the front and rear sides of the gear to move. When the rack disengages from the groove, the top plate can be opened to maintain the internal components, thus facilitating the maintenance of the circuit breaker.

[0004] According to the aforementioned reference materials, the device uses a knob to rotate the gear inside the convex plate. This rotation of the gear then moves the rack meshing with it on the front and rear sides. Once the rack disengages from the groove, the top plate can be opened to inspect the internal components. After maintenance, the convex plate is simply inserted into the housing, and then the knob is rotated in the opposite direction. This causes the rack to re-insert into the groove, thus securing the convex plate and top plate, facilitating circuit breaker maintenance. However, when maintaining a pole-mounted circuit breaker, the protective housing must be removed before the top plate can be removed, which is inconvenient and affects the maintenance efficiency. This hinders rapid maintenance of the pole-mounted circuit breaker and reduces the device's overall effectiveness. Utility Model Content

[0005] Therefore, it is necessary to provide a pole-mounted circuit breaker that is easy to maintain to address the YYY problem.

[0006] The circuit breaker includes a main body with a base plate rotatably connected to its bottom end; a maintenance mechanism, which is located on the inner wall of the main body to facilitate quick maintenance of the pole-mounted circuit breaker; wherein the maintenance mechanism includes two push blocks slidably connected to the front end of the inner wall of the main body, the bottom end of each push block being fixedly connected to a locking block, a locking groove being provided at one end of the top of the base plate, and the two locking blocks respectively engaging with the two sides of the inner wall of the locking groove; and a protective component being provided on the inner wall of the main body.

[0007] In one embodiment, the maintenance mechanism further includes two support rods fixedly connected to the other end of the push block, and two compression springs are provided between the two push blocks, with both ends of the compression springs sleeved on the outer wall of the support rods.

[0008] In one embodiment, a handle is fixedly connected to the bottom end of the base plate.

[0009] In one embodiment, one end of the pusher block extends through the outer wall of the circuit breaker body.

[0010] In one embodiment, the protective assembly includes several lights evenly arranged and installed on both sides of the inner wall of the circuit breaker body, with one end of each light tilted upwards.

[0011] In one embodiment, a sealing gasket is fixedly connected to the top of the base plate, and the top of the sealing gasket is in contact with the inner wall of the circuit breaker body.

[0012] In one embodiment, two baffles are fixedly connected to the front end of the circuit breaker body, and the two baffles are respectively disposed above the two push blocks.

[0013] Beneficial effects

[0014] 1. The above-mentioned easy-to-maintain pole-mounted circuit breaker has two push blocks and two locking blocks in the main body of the circuit breaker in an L-shape. Pushing one end of the push block can move the locking block in the slot. The bottom end of the locking block is arc-shaped, the top end of the locking block is flat, and the top end of the slot is inclined. The bottom end of the locking block contacts the top end of the slot, which can move the locking block from one side to the middle. It can be quickly installed on the base plate. The two push blocks can be supported by the support rod and the compression spring, so that the locking block is embedded in the slot. Pushing the push block can move the locking block and quickly open and close the base plate. The handle can easily control the position of the base plate, which facilitates the maintenance of the pole-mounted circuit breaker and improves the maintenance effect of the device.

[0015] 2. When maintaining the pole-mounted circuit breaker, multiple lights on both sides of the inner wall of the circuit breaker body can illuminate the equipment inside the circuit breaker body. The lights are tilted to one side to facilitate illumination of the inside of the circuit breaker body, improving the maintenance effect of the pole-mounted circuit breaker. The sealing gasket can seal the connection between the circuit breaker body and the base plate. The baffle is set above the two push blocks to reduce the impact of the external environment on the push blocks, which can enable quick maintenance of the pole-mounted circuit breaker.

[0028] The following is combined Figures 1-4 This invention describes a pole-mounted circuit breaker that is easy to maintain.

[0029] In one embodiment, a pole-mounted circuit breaker that is easy to maintain includes a circuit breaker body 100, with a base plate 200 rotatably connected to the bottom end of the circuit breaker body 100; a maintenance mechanism 300, which is disposed on the inner wall of the circuit breaker body 100 to facilitate quick maintenance of the pole-mounted circuit breaker; wherein, the maintenance mechanism 300 includes two push blocks 310 slidably connected to the front end of the inner wall of the circuit breaker body 100, with a locking block 320 fixedly connected to the bottom end of the push block 310, and a locking groove 330 opened at one end of the top of the base plate 200, with the two locking blocks 320 respectively engaging with the two sides of the inner wall of the locking groove 330, and a protective component 370 provided on the inner wall of the circuit breaker body 100.

[0030] It should be noted that a pole-mounted circuit breaker mainly consists of: fixed contacts, movable contacts, contact springs, opening and closing mechanism, and circuit breaker body. The pole-mounted circuit breaker disconnects the circuit by generating an electric arc on the faulty circuit. When a short circuit or overload occurs in the circuit, the current will increase instantaneously, generating high temperature and high pressure, causing an electric arc discharge phenomenon inside the circuit breaker. At this time, the contact spring will separate the moving contact and the fixed contact, disconnect the fault circuit, and stop the arc discharge. When maintaining the pole-mounted circuit breaker, the maintenance mechanism 300 drives two locking blocks 320 to embed into the locking slot 330 through two push blocks 310. The locking blocks 320 and the locking slot 330 can quickly open the base plate 200 to maintain the equipment inside the circuit breaker body 100. The protective component 370 can illuminate the equipment inside the circuit breaker body 100 through the lighting lamp 371. The sealing gasket 372 can improve the sealing of the circuit breaker body 100. The maintenance mechanism 300 and the protective component 370 work together to facilitate the opening and maintenance of the pole-mounted circuit breaker without affecting its normal use.

[0031] like Figure 2 and Figure 3 As shown, the maintenance mechanism 300 also includes two support rods 340 fixedly connected to the other end of the push block 310. Two compression springs 350 are provided between the two push blocks 310. Both ends of the compression springs 350 are sleeved on the outer wall of the support rods 340. A handle 360 ​​is fixedly connected to the bottom end of the base plate 200. One end of the push block 310 extends through to the outer wall of the circuit breaker body 100.

[0032] In this embodiment, by pushing and pulling two push blocks 310, the locking block 320 can slide within the locking slot 330, allowing the base plate 200 to be opened and closed, facilitating maintenance of the circuit breaker body 100. The two push blocks 310 can be compressed by two support rods 340 at the other end, releasing the restriction on the push blocks 310. The elastic force generated by the compression springs 350 can support the push blocks 310, allowing the push blocks 310 to move to one end and return to their original position. The arc surface at the bottom of the locking block 320 cooperates with the inclined surface at the top of the locking slot 330 to quickly close the base plate 200, enabling rapid maintenance of the pole-mounted circuit breaker and improving the effectiveness of the device.

[0033] like Figure 4 As shown, the protective assembly 370 includes several lighting lamps 371 evenly arranged and installed on both sides of the inner wall of the circuit breaker body 100. One end of the lighting lamp 371 is tilted upward. A sealing gasket 372 is fixedly connected to the top of the base plate 200. The top of the sealing gasket 372 is in contact with the inner wall of the circuit breaker body 100. Two baffles 373 are fixedly connected to the front end of the circuit breaker body 100. The two baffles 373 are respectively set above the two push blocks 310.

[0034] In this embodiment, the circuit breaker body 100 rotates the base plate 200 downwards to open, and the hidden power supply inside the circuit breaker body 100 illuminates the lighting lamp 371. The lighting lamp 371 tilts to one side to illuminate the equipment inside the circuit breaker body 100, making it convenient for staff to maintain the pole-mounted circuit breaker. The sealing gasket 372 can improve the sealing effect between the base plate 200 and the circuit breaker body 100, and the baffle 373 can protect the two push blocks 310, which can improve the maintenance effect of the pole-mounted circuit breaker.

[0035] Working principle: When maintaining the pole-mounted circuit breaker, manually pull one end of the two push blocks 310 to move the two locking blocks 320 from the middle of both sides and squeeze the two compression springs 350. The locking blocks 320 move out from both sides of the inner wall of the locking slot 330 to release the restriction on the base plate 200. The base plate 200 can be rotated open by the handle 360. When the pole-mounted circuit breaker is opened, the lighting lamp 371 is turned on by the power switch on the outside of the circuit breaker body 100. The multiple lighting lamps 371 can illuminate the inner wall of the circuit breaker body 100, which facilitates the maintenance of the pole-mounted circuit breaker.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
