Description

Technical Field

[0001] This application relates to the field of circuit breaker technology, specifically to a capacitor-type integrated primary and secondary pole-mounted circuit breaker. Background Technology

[0002] A pole-mounted circuit breaker is a circuit breaker installed and operated on a utility pole. It is a switching device that can disconnect or connect a line under normal conditions, and, in the event of a short-circuit fault, manually or automatically switch the faulty line through operation or relay protection. Pole-mounted circuit breakers are mainly used for sectional switching, control, and protection of power distribution lines, and can interrupt and close short-circuit currents. Currently, outdoor AC high-voltage intelligent vacuum circuit breakers are mainly used in power distribution lines. Intelligent vacuum circuit breakers have fault detection, protection and control, and communication functions.

[0003] Chinese patent document CN222619657U discloses a primary and secondary integrated pole-mounted circuit breaker, specifically disclosing the pole-mounted circuit breaker body. A support base plate is fixedly installed at the bottom of the pole-mounted circuit breaker body, and a support frame is fixedly installed on one side of the pole-mounted circuit breaker body and at the top of the support base plate. A protective shielding component is fixedly installed on the top of the support frame, and an adjustment component is installed on the side of the support frame away from the pole-mounted circuit breaker body. This utility model can prevent the primary and secondary integrated pole-mounted circuit breaker from being directly exposed to the outside during use, reduce the impact of sunlight and rain, improve its service life, and thus facilitate better practicality.

[0004] However, the aforementioned patent has a fixed position for the fixing holes during installation. When the line is slightly off-center, it is impossible to fine-tune the installation position of the circuit breaker, which in turn affects the installation effect of the circuit breaker. Utility Model Content

[0005] To overcome the problem that existing circuit breakers cannot be finely adjusted in position during installation, this application provides a capacitor-type integrated primary and secondary pole-mounted circuit breaker.

[0006] This application adopts the following technical solution: a capacitor-type primary and secondary integrated pole-mounted circuit breaker, including a housing and a solid-sealed pole, an operating mechanism is provided inside the housing, the solid-sealed pole is located at the top of the housing, a mounting base is provided at the bottom of the housing, and a mounting plate is also included, the mounting plate extends along the length direction of the housing, and the mounting plate is mounted on a pole;

[0007] The top of the mounting plate is provided with a groove, and a pair of sliders are provided in the groove. The pair of sliders can slide in the groove, and the top of the sliders is provided with an upwardly extending threaded post.

[0008] The mounting base is provided with a waist hole, and the threaded post can be inserted into the waist hole. The threaded post is provided with a nut for locking the mounting base.

[0009] Optionally, the mounting base is L-shaped, with its vertical end connected to the bottom of the housing and its horizontal end abutting against the slider.

[0010] Optionally, the width of the mounting plate is smaller than the width of the mounting base.

[0011] Optionally, the radial cross-section of the slide groove is convex, and a plurality of support bars are provided on the inner wall of the slide groove. The slider is adapted to be disposed on the inner side of the slide groove, and the plurality of support bars clamp the slider.

[0012] Optionally, the bottom of the chute is provided with a plurality of limiting holes, and the plurality of limiting holes are spaced apart along the length direction of the chute;

[0013] The slide groove is also provided with two limiting blocks. The limiting blocks have through holes that can be coaxially arranged with corresponding limiting holes. The limiting holes are threaded holes, and a screw is inserted through the through holes. After the screw passes through the through holes, it is adapted to be screwed into the limiting holes. The two sliders are located between the limiting blocks.

[0014] Optionally, when the screw is screwed into the corresponding limiting hole, the limiting block and the slider are in contact.

[0015] Compared with the prior art, this application fixes the mounting base inside the slider, and adjusts the position of the housing by sliding the slider in the groove, ensuring that there is no misalignment between the housing and the line, and improving the installation accuracy and reliability of the circuit breaker.

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-4 As shown, a capacitor-type integrated primary and secondary pole-mounted circuit breaker includes a housing 1 and a solid-sealed pole 2. The housing 1 is equipped with an operating mechanism. The solid-sealed pole 2 is located at the top of the housing 1. The bottom of the housing 1 is equipped with a mounting base 3. The circuit breaker also includes a mounting plate 4, which extends along the length of the housing 1. The mounting plate 4 is mounted on a utility pole. Specifically, a clamp can be installed at the bottom of the mounting plate 4. After the clamp is fitted onto the utility pole, it is locked to achieve a reliable connection between the mounting plate 4 and the utility pole.

[0023] The top of the mounting plate 4 is provided with a groove 41, and a pair of sliders 42 are provided in the groove 41. The pair of sliders 42 can slide in the groove 41, and the top of the sliders 42 is provided with an upwardly extending threaded post 421. The mounting base 3 is provided with a waist hole 30, and the threaded post 421 can be inserted into the waist hole 30. The threaded post 421 is provided with a nut 422 for locking the mounting base 3. The top of the housing 1 is also provided with a lifting lug 10, which serves as a connection point for hoisting. After the mounting plate 4 is fixed, a crane can be used to hoist the housing 1. When the mounting base 3 is close to the mounting plate 4 and is about to be at the same height as the threaded post 421, the sliders 42 are pushed to slide in the groove 41, so that the threaded post 421 can be aligned with the waist hole 30 on the mounting base 3. This ensures that after the housing 1 is hoisted, the threaded post 421 can be reliably inserted into the waist hole 30. When the threaded post 421 is inserted into the waist hole 30 and the mounting base 3 is in contact with the slider 42, the nut 422 is screwed into the threaded post 421, thereby achieving a reliable connection between the slider 42 and the mounting base 3. At this time, pushing the housing 1 can drive the slider 42 to slide in the slide groove 41, which also realizes the fine adjustment of the position of the housing 1, ensuring that the housing 1 can meet the installation requirements of the circuit after final positioning.

[0024] The mounting base 3 is L-shaped. The vertical end of the mounting base 3 is connected to the bottom of the housing 1, and the horizontal end of the mounting base 3 is attached to the slider 42. In this way, after the mounting base 3 is installed, the bottom of the housing 1 is in a suspended state, which can promote the heat dissipation of the housing 1.

[0025] The width of the mounting plate 4 is smaller than the width of the mounting base 3. That is, when the mounting base 3 is hoisted to the top of the mounting plate 4, both ends of the mounting base 3 extend to the outside of the mounting plate 4. In this way, the installer can observe the relative position between the mounting base 3 and the mounting plate 4 from bottom to top, ensuring that the position of the housing 1 can still be reliably adjusted under extreme conditions.

[0026] The radial cross-section of the slide groove 41 is convex. Several support bars 411 are provided on the inner wall of the slide groove 41. The slider 42 is adaptedly disposed on the inner side of the slide groove 41, and the support bars 411 clamp the slider 42. When the slider 42 slides into the slide groove 41 from both ends, it can only slide conveniently along the length of the slide groove 41 and cannot detach from it, ensuring that the mounting base 3 and the housing 1 can be reliably fixed on the mounting plate 4. The arrangement of the support bars 411 reduces the contact area between the slider 42 and the slide groove 41, thereby reducing friction and allowing the slider 42 to slide more smoothly within the slide groove 41.

[0027] The bottom of the slide groove 41 is provided with a plurality of limiting holes 412, which are spaced apart along the length of the slide groove 41. Two limiting blocks 43 are also provided inside the slide groove 41. Each limiting block 43 has a through hole that can be coaxially aligned with the corresponding limiting hole 412. The limiting hole 412 is a threaded hole, and a screw 430 passes through it. After passing through the through hole, the screw 430 is screwed into the limiting hole 412, with the two sliders 42 located between the limiting blocks 43. When the screw 430 is screwed into the corresponding limiting hole 412, the limiting block 43 and the slider 42 are in contact.

[0028] After the housing 1 has been positioned, the limiting block 43 is placed into the slide groove 41, and the position of the slider 42 is then finely adjusted so that the through hole on the limiting block 43 is coaxial with the nearest limiting hole 412. Finally, the screw 430 is screwed into the through hole and the limiting block 43, thus fixing the limiting block 43 in the slide groove 41. Once both limiting blocks 43 are fixed, the position of the slider 42 is also in a fixed state that cannot be adjusted. Furthermore, by increasing the density of the limiting holes 412, the sliding and positioning accuracy of the slider 42 can be improved, maximizing the chance that the housing 1 can be displaced to the optimal position.

[0029] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
