Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a capacitor-powered, deeply integrated primary and secondary pole-mounted circuit breaker. Background Technology

[0002] The capacitor-powered, fully integrated primary and secondary pole-mounted circuit breaker is a new type of intelligent power device that integrates modern electronic technology with traditional power equipment. This circuit breaker is mainly used in 10kV distribution networks to improve power supply reliability and automation levels.

[0003] Existing integrated primary and secondary pole-mounted circuit breakers are relatively heavy and require transportation during installation. For example, existing patent (202222427407.5) proposes an integrated primary and secondary pole-mounted circuit breaker, including a main body and a base. The main body is placed on the base, and the four corners of the base bottom wall are recessed to form mounting grooves. Each of the four mounting grooves is equipped with a receiving column, and each receiving column is equipped with a caster wheel at its bottom. The two opposite side walls of the main body are provided with two movable holes, that is, there are four movable holes in total. The four movable holes are respectively connected to the four mounting grooves. Each movable hole is equipped with a second spring and a rebound block. The two ends of the second spring are fixedly connected to the inner wall of the movable hole and the side wall of the rebound block, respectively. The side wall of the receiving column facing the movable hole is recessed to form a lower side groove and an upper side groove. This integrated primary and secondary pole-mounted circuit breaker allows the main body to move easily with the rolling of four casters, eliminating the hassle of using external tools for transportation or manual handling. As can be seen from the above, most of the casters in the existing technology are non-removable and are not convenient for stable placement of the entire device when transportation is not required. Therefore, we propose a capacitor-powered integrated primary and secondary pole-mounted circuit breaker. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a capacitor-powered, fully integrated primary and secondary pole-mounted circuit breaker, including a housing 1, a mounting bracket 2 fixedly installed at the bottom of the housing 1, a pole post 3 fixedly installed at the top of the housing 1, two sets of positioning posts 5 fixedly installed on both sides of the outer side of the housing 1, a threaded post 6 fixedly connected to one side of the positioning post 5, a transfer mechanism 7 for transfer is provided on the threaded post 6, a switching mechanism 8 for switching the use state of the transfer mechanism 7 is provided on the transfer mechanism 7, and a wire harness positioning mechanism 4 is provided on the outside of the pole post 3 to prevent the connecting wire from detaching from the pole post 3.

[0018] The wiring harness positioning mechanism 4 can position the connecting wire after it is connected to the pole post 3, preventing the connection between the connecting wire and the pole post 3 from coming loose. When the entire device needs to be transported, the transport mechanism 7 can be inserted into the outside of the threaded post 6 for easy transport. When the transport needs to be temporarily stopped, the conversion mechanism 8 can switch the use state of the transport mechanism 7, causing the transport mechanism 7 to retract and the mounting frame 2 to fall to the ground, thus facilitating the stable placement of the housing 1 and the pole post 3.

[0019] Please see Figure 1 and Figure 2The transfer mechanism 7 includes a first connecting frame 9, a second connecting frame 10, a transfer wheel 11, and a locking nut 12. The first connecting frame 9 and the second connecting frame 10 are respectively sleeved on the outside of the two sets of threaded columns 6. The first connecting frame 9 and the second connecting frame 10 are connected and fixed by a conversion mechanism 8. The locking nut 12 is threadedly connected to the outside of the threaded column 6. The transfer wheel 11 is fixedly installed at the bottom of both the first connecting frame 9 and the second connecting frame 10.

[0020] When the entire device needs to be transported, the first connecting frame 9 and the second connecting frame 10 are fitted onto the outside of the two sets of threaded columns 6, and then the locking nut 12 is threadedly connected to the threaded column 6. This completes the installation of the first connecting frame 9 and the second connecting frame 10, allowing the transfer wheel 11 to contact the ground, which facilitates the transport of the entire device.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The conversion mechanism 8 includes a rotating shaft 13, a positioning rod 14, a mounting plate 16, a spring 17, a first blocking post 18, a positioning hook 19, and a second blocking post 20. The positioning rod 14 is rotatably connected to the first connecting frame 9 via the rotating shaft 13. The bottom of the positioning rod 14 is fixedly connected to the positioning hook 19, and the bottom of the positioning hook 19 is inclined. The spring 17 is fixedly connected to the first connecting frame 9 via the mounting plate 16. One end of the spring 17 is fixedly connected to the positioning rod 14. The second blocking post 20, which is inserted into the positioning hook 19, is fixedly connected to one side of the second connecting frame 10. The first blocking post 18, which fits against one side of the positioning rod 14, is fixedly installed on the first connecting frame 9. The drive plate 15 is fixedly connected to one side of the positioning rod 14.

[0022] When it is necessary to separate the first connecting frame 9 and the second connecting frame 10, the drive plate 15 is pushed to make the positioning rod 14 rotate along the rotating shaft 13. This allows the positioning hook 19 to move away from the second blocking post 20. Then, due to the weight of the housing 1 itself, the first connecting frame 9 and the second connecting frame 10 can rotate along the threaded post 6, so that the mounting frame 2 can fall directly to the ground, ensuring that the entire device can be temporarily stored. When it is necessary to connect the first connecting frame 9 and the second connecting frame 10, the drive plate 15 is pushed in the opposite direction to make the positioning rod 14 rotate again. The bottom of the positioning hook 19 is inclined, which makes it easy for the positioning hook 19 to engage with the second blocking post 20. The first blocking post 18 can limit the contact of the other end of the positioning rod 14.

[0023] Please see Figure 1 and Figure 2The wire harness positioning mechanism 4 includes a connecting ring 21, a locking bolt 22, a third connecting frame 23, and a snap-fit ​​seat 24. The connecting ring 21 is rotatably connected to the outside of the pole post 3. The locking bolt 22, which contacts the outside of the pole post 3, is threaded onto the connecting ring 21. The third connecting frame 23 is fixedly connected to one side of the connecting ring 21. The snap-fit ​​seat 24 is fixedly installed on the top of the third connecting frame 23. The top of the snap-fit ​​seat 24 has a placement groove 25. The snap-fit ​​seat 24 is made of an elastic material. One side of the snap-fit ​​seat 24 is tapered.

[0024] When the connecting wire needs to be installed, the connecting ring 21 is rotated along the outside of the pole post 3 to avoid the connecting wire harness. After the connecting wire is connected to the pole post 3, the connecting ring 21 is repositioned using the locking bolt 22. Then, the connecting wire harness is inserted into the inside of the snap-fit ​​seat 24 through the placement groove 25. In this way, the snap-fit ​​seat 24, which is made of elastic material, can be used to snap and position the connecting wire.

[0025] In use, firstly, the wiring harness positioning mechanism 4 positions the connecting wire after it is connected to the pole post 3, preventing the connection from loosening. When the entire device needs to be transported, the transport mechanism 7 can be inserted into the outside of the threaded post 6 for easy transport. When transport needs to be temporarily stopped, the conversion mechanism 8 can switch the operating state of the transport mechanism 7, retracting it and lowering the mounting frame 2 to the ground, thus facilitating the stable placement of the housing 1 and the pole post 3. When the entire device needs to be transported, the first connecting frame 9 and the second connecting frame 10 are fitted onto the outside of the two sets of threaded posts 6, and then the locking nut 12 is threaded into the threaded post 6, thus completing the installation of the first connecting frame 9 and the second connecting frame 10, allowing the transport wheel 11 to contact the ground for easy transport. When the first connecting frame 9 and the second connecting frame 10 need to be separated, the drive plate 15 is pushed, causing the positioning rod 14 to rotate along the rotating shaft 13. To make the positioning hook 19 and the second blocking post 20 move away from each other, the weight of the housing 1 itself allows the first connecting frame 9 and the second connecting frame 10 to rotate along the threaded post 6, so that the mounting frame 2 can be placed directly on the ground, ensuring that the entire device can be temporarily stored. When the first connecting frame 9 and the second connecting frame 10 need to be connected to each other, the drive plate 15 is pushed in reverse to make the positioning rod 14 rotate again. The bottom of the positioning hook 19 is inclined, which makes it easy for the positioning hook 19 and the second blocking post 20 to engage with each other. The first blocking post 18 can limit the contact of the other end of the positioning rod 14. When the connecting wire needs to be installed, the connecting ring 21 is rotated along the outside of the pole post 3, so that the connecting wire harness can be avoided. After the connecting wire is connected to the pole post 3, the connecting ring 21 is repositioned using the locking bolt 22. Then the connecting wire harness is inserted into the inside of the snap-fit ​​seat 24 through the placement groove 25. In this way, the snap-fit ​​seat 24 made of elastic material can be used to snap and position the connecting wire.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
