Description

Technical Field

[0001] The present application relates to the technical field of pole-mounted circuit breakers, and in particular to a primary-secondary fusion pole-mounted circuit breaker. Background Art

[0002] The primary and secondary integrated pole-mounted circuit breaker is a new type of distribution equipment in the context of smart grid. Its essence is to deeply integrate the primary equipment (pole-mounted circuit breaker) and secondary equipment (such as measurement, protection, and control units) in the traditional power system. The pole-mounted circuit breaker needs to be placed in a horizontal position to reduce problems with equipment performance and operational reliability caused by tilt.

[0003] In the related art, a pole-mounted circuit breaker includes a housing, in which an operating mechanism is arranged, and the operating mechanism is used to implement opening and closing operations.

[0004] The pole-mounted circuit breaker relies on a set of precise operating mechanisms. If the pole-mounted circuit breaker is not in a horizontal position, the transmission efficiency of the operating mechanism will be reduced and the operating mechanism will generate additional stress, resulting in uneven force on some shafts, connecting rods and other structures in the operating mechanism, thereby reducing the service life of the operating mechanism in the pole-mounted circuit breaker.

[0005] The pole-mounted circuit breaker is installed on a cement board. The surface of the cement board is not level when it is formed, which will cause the pole-mounted circuit breaker to be not level. Therefore, the staff needs to trim the cement board, which makes the installation of the pole-mounted circuit breaker more complicated. Summary of the Invention

[0006] In order to improve the problem that the placement position of the pole-mounted circuit breaker may be tilted, the present application provides a primary and secondary fusion pole-mounted circuit breaker.

[0007] This application provides a primary and secondary integrated pole-mounted circuit breaker, which adopts the following technical solutions: A primary-secondary fusion column-mounted circuit breaker comprises a shell and a support seat, a support bar being rotatably connected to the surface of the shell, a support ball being fixedly connected to the surface of the support bar, a support groove for the support ball to rotate being formed on the support seat, and an elastic ring being sleeved on the support ball; when the support ball is located in the support groove and the elastic ring abuts against the groove wall of the support groove, the shell is fixed to the support seat.

[0008] By adopting the above technical solution, the supporting ball rotates in the supporting groove, so that the supporting ball can change its angle in the supporting groove, so that the distance between the shell and the supporting seat can be adjusted. In addition, the elastic ring abuts the groove wall of the supporting groove, so that the elastic ring can limit the rotation of the supporting ball in the supporting groove, thereby reducing the possibility of shaking between the supporting ball and the shell, allowing the staff to rotate the supporting ball in the supporting groove, so that the angle between the shell and the supporting seat can be adjusted, so that the shell can remain horizontal, reducing the impact on the use of the pole-mounted circuit breaker due to the uneven surface of the cement board; at the same time, because the elastic ring abuts the supporting ball, the elastic ring can limit the support ball to produce a small range of rotation, that is, the elastic ring limits the shell to produce a small range of shaking, so that the shell is not easily affected by shaking. The operating mechanism is not easily affected by the operating mechanism.

[0009] Optionally, a sliding groove is provided on the shell, a sliding slope is provided on the bottom wall of the sliding groove, the distance between the sliding slope and the ground gradually increases along the direction from the support bar to the sliding groove, and a fixing bar is slidably connected to the sliding slope; when the fixing bar abuts the support seat, the shell is pre-fixed on the support seat.

[0010] By adopting the above technical solution, the fixing bar slides on the sliding inclined surface, allowing the fixing bar to move along the sliding inclined surface, so that the fixing bar can adjust the distance between the support base and the shell, and the fixing bar can realize pre-fixation between the shell and the support base, so that the staff can measure whether the shell is level, thereby allowing the staff to quickly install and fix the pole-mounted circuit breaker.

[0011] Optionally, the fixing strip is provided with a fixing block, the fixing block is provided with a plurality of first fixing holes, the support seat is provided with a plurality of second fixing holes, the fixing block is provided with a fastener, and the fastener is used to be inserted into the first fixing hole and the second fixing hole; when the fastener is inserted into the first fixing hole and the second fixing hole, the fixing strip is fixed to the support seat.

[0012] By adopting the above technical solution, the fixing block is inserted into the first fixing hole and the second fixing hole, so that the fixing block can fix the fixing bar, and the fixing bar can be fixed on the support base, so that the fixing bar can stably support the shell and reduce the possibility of the shell and the support base rotating with each other.

[0013] Optionally, a limiting spring piece is provided on the support seat, and the limiting spring piece is deformed toward the ground. The limiting spring piece is located on the side of the elastic ring away from the ground.

[0014] By adopting the above technical solution, the limiting spring piece is deformed toward the ground, so that the limiting spring piece can squeeze the elastic ring, allowing the elastic ring to abut the support ball more compactly, reducing the possibility of the support ball rotating in the support groove.

[0015] Optionally, a stop bar is slidably connected to the support seat, and the stop bar is located between the fixed block and the limiting spring piece; when the fixed block is fixed on the support seat, the stop bar abuts against the surface of the limiting spring piece away from the elastic ring.

[0016] By adopting the above technical solution, the stop bar is located between the fixed block and the limiting spring piece, so that the stop bar can limit the movement of the limiting spring piece in the direction away from the elastic ring, allowing the limiting spring piece to better abut the elastic ring, further increasing the limiting effect of the elastic ring on the support ball.

[0017] Optionally, a accommodating bar is rotatably connected to the support bar, a first accommodating block is provided on one end of the accommodating bar, and a second accommodating block is provided on the other end of the accommodating bar, the first accommodating block is located on the insertion path of the elastic ring, and the rotation path of the second accommodating block intersects with the movement path of the limiting spring away from the elastic ring; when the elastic ring abuts the second accommodating block, the first accommodating block abuts the side of the limiting spring away from the elastic ring.

[0018] By adopting the above technical solution, when the elastic ring is inserted into the supporting groove, the elastic ring abuts the second accommodating block, allowing the second accommodating block to drive the accommodating bar to rotate, so that the accommodating bar can drive the first accommodating block to move. In addition, the rotation path of the first accommodating block and the movement path of the limiting spring piece away from the elastic ring intersect, so that the first accommodating block can abut the side of the limiting spring piece away from the elastic ring, so that the limiting spring piece can apply a force to the elastic ring more stably, so that the elastic ring can stably support the supporting ball; by installing the elastic ring, the limiting spring piece on the elastic ring is further strengthened, reducing the movement of the elastic ring in the supporting groove, allowing the supporting ball to be stably located in the support groove, and reducing the possibility of the support ball rotating in the support groove.

[0019] Optionally, a receiving groove is provided on the surface of the limiting spring piece away from the elastic ring, and the receiving groove is for inserting the second receiving block; when the second receiving block is inserted into the receiving groove, the limiting spring piece abuts against the elastic ring.

[0020] By adopting the above technical solution, the second accommodating block is inserted into the accommodating groove, so that the second accommodating block can better abut the limiting spring piece, reduce the mutual sliding between the limiting spring piece and the second accommodating block, and enable the second accommodating block to apply force to the limiting spring piece more stably.

[0021] Optionally, a metal damping disk is provided on the shell, a permanent magnet array is provided on the support seat, and the metal damping disk is located above the permanent magnet array; when the shell swings, a force is generated between the permanent magnet array and the metal damping disk.

[0022] By adopting the above technical solution, a metal damping disk is set on the support seat, and the metal damping disk is located above the permanent magnet array. When the shell swings, the shell will drive the metal damping disk to move. When the metal damping disk moves on the permanent magnet array, the metal damping disk will generate a force opposite to the movement when passing through the magnetic field, thereby slowing down the shaking of the shell.

By rotating the supporting ball in the supporting groove, the supporting ball can change its angle in the supporting groove, so that the distance between the shell and the supporting seat can be adjusted. In addition, the elastic ring abuts the groove wall of the supporting groove, so that the elastic ring can limit the rotation of the supporting ball in the supporting groove, thereby reducing the possibility of shaking between the supporting ball and the shell. The staff can rotate the supporting ball in the supporting groove, so that the angle between the shell and the supporting seat can be adjusted, so that the shell can remain horizontal, reducing the impact on the use of the pole-mounted circuit breaker due to the uneven surface of the cement board; at the same time, because the elastic ring abuts the supporting ball, the elastic ring can limit the support ball to produce a small range of rotation, that is, the elastic ring limits the shell to produce a small range of shaking, so that the shell is not easily affected by shaking. The operating mechanism is not easily affected by the operating mechanism.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] This embodiment discloses a primary and secondary fusion column mounted circuit breaker. Figure 1 A primary / secondary integrated column-mounted circuit breaker comprises a housing 1 and a support base 2. Housing 1 houses an operating mechanism for controlling opening and closing. Support base 2 is positioned on the side of housing 1 closest to the ground. A spirit level 11 is fixedly attached to housing 1 to measure whether housing 1 is level.

[0029] Reference Figure 1 and Figure 2 The support base 2 has a support groove 22 on its surface away from the ground, and an annular groove 221 is formed on the wall of the support groove 22. The surface of the housing 1 close to the ground is rotatably connected to a support bar 211, and the surface of the support bar 211 away from the housing 1 is integrally formed with a support ball 21, and the support ball 21 can rotate within the support groove 22.

[0030] Reference Figure 2 and Figure 3 The support bar 211 is provided with an elastic ring 23. The elastic ring 23 is elastic. When the support ball 21 is inserted into the support groove 22, the elastic ring 23 is fitted into the support ball 21 and abuts against the groove wall of the annular groove 221, so that the elastic ring 23 can limit the rotation of the support ball 21 in the support groove 22. At this time, the housing 1 can be fixed to the support base 2.

[0031] Reference Figure 2 and Figure 3The surface of the housing 1 close to the ground is provided with a plurality of sliding grooves 12, which are distributed in a circumferential array along the support bar 211. A sliding slope 121 is provided on the bottom wall of the sliding groove 12, and the distance between the sliding slope 121 and the ground gradually increases along the direction from the support bar 211 to the sliding groove 12. A fixed bar 122 is slidably connected to the surface of the sliding slope 121, and the fixed bar 122 extends in the vertical direction. A buffer block 123 is fixedly connected to the end surface of the fixed bar 122 away from the housing 1. The buffer block 123 is elastic and abuts the support frame.

[0032] Reference Figure 2 and Figure 3 When the buffer block 123 abuts the support base 2, the fixing bar 122 can pre-fix the support base 2 and the shell 1, so that the support base 2 can be stably located in the shell 1, so that the staff can measure whether the shell 1 is in a horizontal position.

[0033] Reference Figure 3 and Figure 4 A fixing block 124 is fixedly connected to the end surface of the fixing bar 122. The fixing block 124 extends horizontally. A fixing plate 128 is integrally formed on the side of the fixing block 124. The fixing plate 128 extends vertically. A plurality of first fixing holes 125 are formed on the surface of the fixing plate 128. The plurality of first fixing holes 125 are arranged in an array along the length of the fixing block 124. A plurality of second fixing holes 126 are formed on the side of the support base 2. The plurality of second fixing holes 126 are arranged in an array along the length of the support base 2. The spacing between the plurality of first fixing holes 125 is smaller than the spacing between the plurality of second fixing holes 126. A fastener 127 is provided on the fixing block 124. The fastener 127 includes a fastening bolt that can be threaded into the first fixing hole 125 and the second fixing hole 126. When the fastening bolt passes through the first fixing hole 125 and is threaded into the second fixing hole 126, the fixing block 124 is fixed to the support base 2.

[0034] Reference Figure 2 and Figure 4 A limiting spring 24 is fixedly connected to the wall of the annular groove 221, and the limiting spring 24 deforms toward the bottom wall of the support groove 22. When the support ball 21 is located in the support groove 22, the limiting spring 24 is located on the side of the elastic ring 23 away from the ground, and the limiting spring 24 restricts the movement of the elastic ring 23 in the annular groove 221.

[0035] Reference Figure 2 and Figure 5The support bar 211 has a rotational groove 212 defined on its outer surface. A receiving bar 213 is rotatably connected within the rotational groove 212. A first receiving block 214 is fixedly connected to one end of the receiving bar 213, and a second receiving block 215 is fixedly connected to the other end of the receiving bar 213. The rotational path of the first receiving block 214 intersects with the movement path of the limiting spring 24 away from the annular groove 221. The rotational path of the second receiving block 215 intersects with the movement path of the elastic ring 23 when it abuts the support ball 21. A receiving groove 241 is defined on the surface of the limiting spring 24 away from the ground, into which the second receiving block 215 is inserted.

[0036] Reference Figure 2 and Figure 5 When the supporting ball 21 is located in the supporting groove 22, the elastic ring 23 is sleeved on the supporting ball 21, and the elastic ring 23 abuts the groove wall of the annular groove 221. At this time, the elastic ring 23 can drive the first accommodating block 214 to rotate, so that the first accommodating block 214 drives the second accommodating block 215 to rotate through the accommodating bar 213. At this time, the second accommodating block 215 can be inserted into the accommodating groove 241, so that the second accommodating block 215 fixes the limiting spring piece 24.

[0037] Reference Figure 4 and Figure 5 The support base 2 has a receiving groove 25 formed on its surface. A movable spring 251 is fixedly connected to the bottom wall of the receiving groove 25. A stop bar 252 is fixedly connected to the surface of the movable spring 251. A stop block 253 is fixedly connected to the surface of the stop bar 252 near the ground. The movable spring 251 drives the stop bar 252 to move away from the support base 2, and the movement path of the stop block 253 intersects the movement path of the fixed block 124.

[0038] Reference Figure 4 and Figure 5 When the fixing block 124 is fixed on the support base 2, the fixing block 124 abuts against the stop bar 252. At this time, the movable spring 251 is in a compressed state, and the stop block 253 abuts against the surface of the limiting spring piece 24 away from the elastic ring 23, allowing the stop bar 252 to limit the limiting spring piece 24.

[0039] Reference Figure 3 and Figure 4A metal damping disk 26 is fixedly connected to the surface of the shell 1 close to the ground, and a permanent magnet array 261 is fixedly connected to the surface of the support base 2 away from the ground. The permanent magnet array 261 is formed by a plurality of permanent magnets arranged along the length of the support base 2, and the plurality of permanent magnets are arranged alternately as positive magnets and negative magnets. The metal damping disk 26 is located directly above the permanent magnet array 261. When the shell 1 shakes on the support base 2, the metal damping disk 26 can move on the permanent magnet array 261, allowing the metal damping disk 26 to move in different magnetic fields, thereby generating a force between the metal damping disk 26 and the permanent magnet array 261, and slowing down the shaking of the shell 1.

[0040] The implementation principle of a primary-secondary integrated pole-mounted circuit breaker in an embodiment of the present application is as follows: the staff first slides the fixing bar 122 to allow the shell 1 to be pre-fixed on the support base 2, and then the staff moves the elastic ring 23 so that the elastic ring 23 is located in the annular groove 221, and the elastic ring 23 pushes the second accommodating block 215 to allow the first accommodating block 214 to be inserted into the accommodating groove 241, so that the limiting spring piece 24 can stably fix the elastic ring 23 and reduce the possibility of the elastic ring 23 moving in the annular groove 221; finally, the fastener 127 is tightened to fix the fixing bar 122.
