Description

Technical Field

[0001] This application relates to the technical field of pole-mounted circuit breakers, and in particular to a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] The integrated pole-mounted circuit breaker is an intelligent power device that integrates primary and secondary equipment. The primary equipment is the circuit breaker body, and the secondary equipment uses intelligent terminals for measurement, control, and protection.

[0003] In related technologies, a primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker housing, an operating mechanism and other components installed inside the circuit breaker housing, and a support plate installed below the circuit breaker housing.

[0004] During the installation of pole-mounted circuit breakers onto concrete bases, the circuit breakers must be installed horizontally. Horizontal installation affects the operation of the operating mechanism, thus impacting the reliability of the pole-mounted circuit breaker. However, since concrete bases are usually pre-cast, it is difficult to guarantee the levelness of the upper surface of the base, thus making it difficult to guarantee the horizontality of the pole-mounted circuit breaker after installation. Summary of the Invention

[0005] To improve the levelness of the pole-mounted circuit breaker installed on the cement base, this application provides a primary and secondary integrated pole-mounted circuit breaker.

[0006] This application provides a primary and secondary integrated pole-mounted circuit breaker, which adopts the following technical solution:

[0007] A primary and secondary integrated pole-mounted circuit breaker includes a housing and a base plate. The housing is disposed on the base plate. A first receiving groove is formed on the end face of the base plate along the length direction, and a first level is disposed in the first receiving groove. A second receiving groove is formed on the end face of the base plate along the width direction, and a second level is disposed in the second receiving groove. Four support legs are disposed below the base plate, and an adjustment structure for adjusting the position of the support legs is provided on the base plate.

[0008] By adopting the above technical solution, the pole-mounted circuit breaker is first installed on the cement base. The position of the bubble in the first level is observed. The position of the support foot is adjusted by adjusting the structure until the position of the bubble in the first level is centered. Similarly, the position of the bubble in the second level is observed. The position of the support foot is adjusted by adjusting the structure until the position of the bubble in the second level is centered, thus realizing the horizontal installation of the pole-mounted circuit breaker on the cement base.

[0009] Optionally, the adjustment structure includes a mounting rod disposed on the support leg, and the lower end face of the base plate is provided with a receiving hole for threaded connection of the mounting rod. The mounting rod is externally threaded with an adjusting nut located above the base plate, and the mounting rod is sleeved with an adjusting spring located below the base plate. The adjusting spring is in a compressed state, with one end of the adjusting spring abutting against the adjusting nut and the other end of the adjusting spring abutting against the base plate.

[0010] By adopting the above technical solution, the installation rod is driven to rotate, which allows the installation rod to move along the axial direction of the receiving hole, so that the pole-mounted circuit breaker is horizontally installed on the cement base; by adjusting the spring, the force applied to the adjusting nut and the base can play a role in preventing loosening between the installation rod and the base.

[0011] Optionally, the support leg includes a fixed seat rotatably connected to the mounting rod, and a fixed plate is rotatably connected to the fixed seat on the side away from the mounting rod, wherein the rotation axis of the fixed seat is perpendicular to the rotation axis of the fixed plate.

[0012] By adopting the above technical solution, the fixed base is driven to rotate around the axis of the mounting rod, and then the fixed base is driven to rotate, so that the fixed plate and the upper surface of the cement base are more closely fitted, the contact surface between the support leg and the horizontal base is increased, and the pole-mounted circuit breaker is more stable on the cement base.

[0013] Optionally, the lower end face of the base plate is provided with a receiving groove communicating with the receiving hole, and the adjustment structure further includes an installation tube that rotates in the receiving groove. The end face of the installation tube is provided with an installation hole, and the installation rod passes through the receiving hole. When the installation tube is perpendicular to the bottom wall of the receiving groove, the installation hole is aligned with the receiving hole.

[0014] By adopting the above technical solution, when both the mounting pipe and the mounting rod are stored in the receiving groove, the space occupied by the pole-mounted circuit breaker is reduced, making it easier to transport the pole-mounted circuit breaker. The mounting pipe is rotated to be perpendicular to the bottom wall of the receiving groove, and then the mounting rod is rotated into the receiving hole and locked to prevent the mounting pipe from rotating. In addition, the position of the support foot can be adjusted by driving the mounting rod to move along the axis of the receiving hole.

[0015] Optionally, the base plate is provided with a first sealing structure for sealing the first storage slot. The bottom wall of the first storage slot has two first sealing grooves, which are distributed along the length of the base plate. The first storage slot is located between the two first sealing grooves. The inner walls of the first sealing grooves that are close to each other are provided with first sealing holes that communicate with the first storage slot. The first sealing structure includes two first sealing strips, each of which is slidably disposed in a first sealing groove. The end faces of the two first sealing strips that are close to each other are provided with first sealing plates that pass through the first sealing holes. When the two first sealing plates are in contact with each other, the first storage slot is in a sealed state.

[0016] By adopting the above technical solution, the two first sealing plates are attached together to seal the first storage tank, making it difficult for dust and foreign objects to enter the first storage tank, and at the same time making it difficult for the first level to come into contact with the outside world, thus reducing the probability of damage to the first level.

[0017] Optionally, a rope is provided on the installation tube, and the end of the rope away from the installation tube is connected to the first sealing strip.

[0018] By adopting the above technical solution, when the installation pipe rotates, it drives the rope to move. The rope pulls the first sealing strip, so that the first sealing strip no longer blocks the first storage slot. This allows the construction personnel to observe the first level on the bottom plate, and the workers can use the first level to horizontally install the pole-mounted circuit breaker on the cement base.

[0019] Optionally, a slot is provided on the end face of the first sealing strip away from the axis of the first storage groove, and an insert rod is inserted into the slot. A deformable locking block is provided on the end face of the insert rod away from the bottom wall of the first sealing groove, and a slot for inserting the locking block is provided on the mounting tube.

[0020] By adopting the above technical solution, during the process of the installation tube rotating from inside the receiving groove to outside the receiving groove, the installation tube drives the first sealing strip to move with the help of the rope, that is, drives the insertion rod and the locking block to move until the locking block contacts the installation tube. At this time, the installation tube has not yet rotated to be perpendicular to the bottom wall of the receiving groove. The installation tube continues to be driven to rotate. The locking block deforms during the process of continuing to move. When the locking block is aligned with the locking groove, the locking block resets and inserts into the locking groove. The locking block can restrict the reverse rotation of the installation tube.

[0021] Optionally, a sealing spring is provided in the first sealing groove. The sealing spring is located on the side of the first sealing strip away from the first sealing plate. The sealing spring is in a compressed state. One end of the sealing spring is fixedly connected to the inner wall of the first sealing groove away from the first sealing hole. The other end of the sealing spring is fixedly connected to the first sealing strip. The outer circumference of the mounting tube has a long groove-shaped linkage groove. The length direction of the linkage groove is consistent with the axial direction of the mounting tube. A linkage slider is slidably arranged in the linkage groove. The side of the rope away from the first sealing strip is connected to the linkage slider. The mounting tube is provided with a positioning element to restrict the sliding of the linkage slider. When the card block is inserted into the card slot, the mounting tube is perpendicular to the bottom wall of the receiving groove.

[0022] By adopting the above technical solution, when the positioning component limits the linkage slider, the rotation of the mounting tube can drive the first sealing strip to move. At the same time, the movement of the first sealing strip drives the sealing spring to compress and deform. The sealing spring applies a force to the first sealing strip in the direction of the first sealing sliding hole. When the mounting tube is perpendicular to the bottom wall of the receiving groove and the locking block is inserted into the slot, it drives the positioning component to release the limit on the linkage slider. At this time, the sealing spring resets and drives the first sealing strip to move in the opposite direction, so that the first sealing plate can re-seal the first storage groove.

[0023] Optionally, a positioning cavity is provided on the bottom wall of the linkage slide groove, the positioning cavity extends away from the mounting axis, and an insertion hole communicating with the positioning cavity is provided on the circumferential surface of the mounting tube. The positioning component includes a positioning plate and a positioning spring disposed in the positioning cavity. The positioning spring is in a compressed state. One end of the positioning spring is fixedly connected to the inner wall of the positioning cavity away from the linkage slide groove, and the other end of the positioning spring is fixedly connected to the positioning plate. The end of the positioning plate away from the positioning spring is provided with a positioning block inserted into the linkage slide groove and a button passing through the insertion hole.

[0024] By employing the above technical solution, a force is applied to the button in the direction of the mounting tube axis. The button moves the positioning plate and positioning block together, while the positioning spring is compressed and deformed until the positioning block disengages from the linkage slide groove and no longer limits the linkage slider.

[0025] Optionally, each of the two first sealing plates has a first groove on its end face that is close to each other, and a first magnet is provided in the first groove, and the two first magnets can be magnetically attracted to each other.

[0026] By adopting the above technical solution, when the two first sealing plates seal the first storage tank, the two first magnets magnetically attract each other, improving the stability of the connection between the two and making it less likely for the two first sealing plates to separate due to accidental contact.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. First, install the pole-mounted circuit breaker onto the cement base. Observe the position of the bubble in the first level and adjust the position of the support legs by adjusting the structure until the position of the bubble in the first level is centered. Similarly, observe the position of the bubble in the second level and adjust the position of the support legs by adjusting the structure until the position of the bubble in the second level is centered, so that the pole-mounted circuit breaker is horizontally installed on the cement base.

[0029] 2. The mounting tube and mounting rod are rotated into the receiving groove, which serves to store the mounting tube and mounting rod. Attached Figure Description

[0083] Reference Figure 5 and Figure 8 Each of the two second sealing plates 72 has a second groove 721 on its adjacent end face. A second magnet 722 is disposed in the second groove 721. The end faces of the second magnets 722 away from the second sealing plates 72 and away from the second sealing strip 71 are coplanar. The two second magnets 722 can magnetically engage. When the second magnets 722 are magnetically engaged, that is, when the two second sealing plates 72 are in contact with each other, they seal the second storage slot 22.

[0084] Reference Figure 5 and Figure 8 An operating hole 28 is provided on the end face of the base plate 2 along its length, and the operating hole 28 communicates with the second sealing groove 27. The operating hole 28 is a horizontal elongated hole. An operating block 281 is slidably disposed in the operating hole 28, and one end of the operating block 281 is fixedly connected to the second sealing strip 71.

[0085] The implementation principle of Example 3 is as follows: First, the installation tube 44 is rotated out of the receiving groove 24. Due to the positioning component 6 limiting the linkage slider 444, the installation tube 44 drives the linkage slider 444 to move. The linkage slider 444 drives the first sealing strip 51, the first sealing plate 52, the insertion rod 514, and the locking block 515 to move together, so that the first sealing plate 52 no longer blocks the first storage groove 21. At the same time, the sealing spring 26 is compressed and deformed until the locking block 515 contacts the installation tube 44. The installation tube 44 continues to rotate, causing the locking block 515 to deform. When the installation tube 44 is perpendicular to the bottom wall of the receiving groove 24, and when the locking block 515 is aligned with the locking groove 447, the locking block 515 resets and inserts into the locking groove 447. Then, the operating block 281 is driven to move, so that the second sealing plate 72 no longer blocks the second storage groove 22. Then, rotate the mounting rod 41 into the receiving hole 23, observe the first level 211 and the second level 221, and adjust the level of the pole-mounted circuit breaker on the cement seat. Finally, press the button 63 so that the positioning block 62 no longer limits the linkage slider 444, the sealing spring 26 resets and drives the first sealing strip 51 and the first sealing plate 52 to move, so that the first sealing plate 52 re-seals the first storage slot 21, and the second sealing plate 72 re-seals the second storage slot 22 through the operating block 281.
