Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a primary and secondary integrated pole-mounted circuit breaker anti-misoperation protection structure. Background Technology

[0002] With the development of Chinese society, the laying of power grids is becoming more and more widespread, and the distribution range of utility poles is also becoming wider. As a result, there are more and more integrated primary and secondary pole-mounted circuit breakers installed on utility poles for power transmission and transfer. Integrated primary and secondary pole-mounted circuit breakers typically include a main body, which contains several electrical components, including but not limited to fuses, load switches, and energy storage components. The main body is equipped with a rotating rod for storing energy in the switch, and a control rod for opening and closing the switch is also installed on the main body.

[0003] Chinese Utility Model Patent Publication No. CN216818235U discloses a primary and secondary integrated pole-mounted circuit breaker with anti-misoperation mechanism. The specification of this anti-misoperation primary and secondary integrated pole-mounted circuit breaker states that when an operator needs to install the main body, a limiting rod is first used to limit the first rotating plate. Then, a snap-fit ​​rod is inserted between the two limiting rods, reducing the probability that the limiting rod will rotate between the first rotating plate and the side wall of the main body, thus releasing the locking of the first rotating plate. An elastic snap-fit ​​block then abuts against the side wall of the limiting rod, reducing the probability of the snap-fit ​​rod slipping out of the snap-fit ​​groove, improving the stability of the limiting rod and the snap-fit ​​rod. It also reduces the probability of the first rotating plate rotating due to accidental contact by the operator, improving the safety of the main body. However, this anti-misoperation primary and secondary integrated pole-mounted circuit breaker only has a single anti-misoperation structure, making it inconvenient to apply to various different scenarios. This results in poor versatility in the overall anti-misoperation structure, hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a primary and secondary integrated pole-mounted circuit breaker anti-misoperation protection structure. It can effectively solve the problem that in the prior art, only a single anti-misoperation structure is designed, which is easy to make it difficult to apply to a variety of different scenarios. As a result, the overall anti-misoperation structure has poor versatility in use, which makes it difficult to promote and use.

[0005] The technical solution adopted by this utility model is: a primary and secondary integrated pole-mounted circuit breaker anti-misoperation protection structure, including an integrated circuit breaker, a control base and a positioning base. A connecting base is rotatably installed at the end of the control base away from the integrated circuit breaker. A control handle is fixedly installed at the end of the connecting base away from the control base. A connecting sleeve is fixedly installed at the end of the positioning base away from the integrated circuit breaker. A protection component is inserted and installed at the end of the integrated circuit breaker close to the control base. The protective assembly includes an insert plate, a positioning plate, and a protective plate. The positioning plate and the protective plate are plugged in. A limit hole is provided at one end of the protective plate near the insert plate. A limit post is slidably connected to the inner edge of the insert plate, and the limit post is adapted to the limit hole.

[0006] Preferably, the integrated circuit breaker has a slot at the end away from the protection component, the slot and the plug plate are plugged in, and the cross-section of the slot and the plug plate is "L" shaped.

[0007] With the above technical solution, through the cooperation of the slot and the insert plate, when installing the insert plate, it can be inserted into the slot. The "L"-shaped structure can restrict the insertion plate from detaching in the horizontal direction and prevent it from shaking in the vertical direction, which can facilitate quick fixation and avoid misalignment during subsequent fixation.

[0008] Preferably, the positioning plate has a mounting hole at the end away from the insertion plate, and the integrated circuit breaker has a positioning bolt threadedly connected to the end away from the positioning plate. The positioning bolt passes through the mounting hole and extends into the interior of the integrated circuit breaker.

[0009] With the above technical solution, after the slot and the plug plate are aligned, the positioning plate can be threaded onto the integrated circuit breaker by passing through the mounting hole of the positioning plate with the positioning bolt. The positioning plate can be installed at the front end of the integrated circuit breaker, which facilitates the subsequent protection of the control handle.

[0010] Preferably, a limiting groove is provided at one end of the insert plate near the protection plate, the limiting groove is slidably connected to the protection plate, and the protection plate is located at the end of the control seat and the connecting seat away from the integrated circuit breaker.

[0011] The above technical solution, through the design of the limiting groove, can guide the protective plate to slide along a fixed track. When closed, it completely covers the control seat and the connecting seat, preventing staff from accidentally touching them. When operation is required, the fixing parts can be unlocked to expose the control components, which can prevent accidental activation of the control switch during handling or movement.

[0012] Preferably, the end of the plug plate away from the integrated circuit breaker has a second mounting hole, the end of the limiting post away from the limiting groove is fixedly mounted with a pull seat, the outer edge of the limiting post is fixedly mounted with a fixing sleeve, the end of the fixing sleeve near the pull seat is fixedly mounted with a spring, and the other end of the spring is fixedly mounted with the plug plate.

[0013] Through the above technical solution, the spring design allows the spring to push the fixing sleeve to drive the limiting post into the limiting hole of the protection plate, thereby locking the protection plate. When unlocking, the pull base can be pulled to compress the spring, causing the limiting post to disengage and unlocking the protection plate. This facilitates quick locking and unlocking, avoids accidental switch activation, and forms a dual anti-accidental activation mechanism to prevent unprofessional personnel from opening the protection plate at will. The unlocking operation is simple and does not affect maintenance efficiency.

[0014] Preferably, the end of the limiting post away from the pull seat has a groove, and the groove has a triangular cross-section.

[0015] The above technical solution guides the limiting post to automatically align with the limiting hole during the sliding of the protective plate using the triangular inclined plane, reducing alignment deviation and facilitating quick locking.

[0016] Preferably, the integrated circuit breaker is fixedly installed with handles and mounting frames at both ends, and a positioning bolt is inserted into one end of the control handle near the connecting sleeve. A through hole is opened at one end of the control handle, and the positioning bolt passes through the through hole and extends into the interior of the connecting sleeve.

[0017] The above technical solution provides a convenient carrying fulcrum through the handle, and the mounting frame ensures that the circuit breaker is firmly installed on the column. With the help of the positioning bolt to limit the rotation of the control handle, it prevents the circuit breaker from being malfunctioned due to unauthorized operation. It can form a variety of anti-accidental contact protection structures, and different protection structures can be selected according to different situations, thereby improving the overall practicality.

[0018] Compared with the prior art, this utility model provides a primary and secondary integrated pole-mounted circuit breaker anti-accidental contact protection structure, which has the following beneficial effects: 1. The anti-accidental touch protection structure of the integrated primary and secondary pole-mounted circuit breaker, through the design of the limit groove, can guide the protection plate to slide along a fixed track. When closed, it completely covers the control seat and the connecting seat to prevent the staff from accidentally touching them. When operation is required, the fixing parts can be unlocked to expose the control components, which can prevent accidental touch of the control switch during handling or movement. 2. This integrated primary and secondary pole-mounted circuit breaker anti-misoperation protection structure restricts the rotation of the control handle by positioning bolts, preventing circuit breaker maloperation caused by unauthorized operation. It can form a variety of anti-misoperation protection structures, and different protection structures can be selected according to different situations, thereby improving the overall practicality.

[0021] 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.

[0022] Example 1: As Figure 1-9 As shown, the present invention provides a primary and secondary integrated pole-mounted circuit breaker anti-misoperation protection structure, including an integrated circuit breaker 1, a control base 4 and a positioning base 7. A connecting base 5 is rotatably installed at the end of the control base 4 away from the integrated circuit breaker 1. A control handle 6 is fixedly installed at the end of the connecting base 5 away from the control base 4. A connecting sleeve 8 is fixedly installed at the end of the positioning base 7 away from the integrated circuit breaker 1. A protection component 12 is plugged into the end of the integrated circuit breaker 1 near the control base 4. The protective component 12 includes an insert plate 1201, a positioning plate 1202, and a protective plate 1205. The positioning plate 1202 and the protective plate 1205 are plugged in. A limiting hole 1206 is provided at one end of the protective plate 1205 near the insert plate 1201. A limiting post 1209 is slidably connected to the inner edge of the insert plate 1201. The limiting post 1209 is adapted to the limiting hole 1206.

[0023] Specifically, the integrated circuit breaker 1 has a slot 10 at the end away from the protection component 12. The slot 10 and the plug plate 1201 are plugged in and installed. The slot 10 and the plug plate 1201 have an "L" shaped cross-section. The advantage is that, through the cooperation of the slot 10 and the plug plate 1201, when installing the plug plate 1201, it can be inserted into the plug plate 1201 along the slot 10. The "L" shaped structure not only restricts the plug plate 1201 from detaching in the horizontal direction, but also prevents it from shaking in the vertical direction, which facilitates quick fixation and avoids misalignment during subsequent fixation.

[0024] Specifically, the positioning plate 1202 has a mounting hole 1203 at the end away from the insertion plate 1201, and the integrated circuit breaker 1 has a positioning bolt 11 threadedly connected to the end away from the positioning plate 1202. The positioning bolt 11 passes through the mounting hole 1203 and extends into the interior of the integrated circuit breaker 1. The advantage is that after the slot 10 and the insertion plate 1201 are aligned, the positioning plate 1202 can be installed at the front end of the integrated circuit breaker 1 by passing through the mounting hole 1203 of the positioning plate 1202 and threadedly connecting to the integrated circuit breaker 1 through the positioning bolt 11, which facilitates the subsequent protection of the control handle 6.

[0025] Specifically, a limiting groove 1204 is provided at the end of the plug plate 1201 near the protection plate 1205. The limiting groove 1204 and the protection plate 1205 are slidably connected. The protection plate 1205 is located at the end of the control seat 4 and the connecting seat 5 away from the integrated circuit breaker 1. The advantage is that the design of the limiting groove 1204 can guide the protection plate 1205 to slide along a fixed track. When closed, it completely covers the control seat 4 and the connecting seat 5 to prevent personnel from accidentally touching them. When operation is required, the fixing parts can be unlocked to expose the control components, which can avoid accidental touch of the control switch when handling or moving.

[0026] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, the end of the plug plate 1201 furthest from the integrated circuit breaker 1 has a mounting hole 1207. A pull base 1208 is fixedly installed at the end of the limiting post 1209 furthest from the limiting groove 1204. A fixing sleeve 1210 is fixedly installed at the outer edge of the limiting post 1209. A spring 1211 is fixedly installed at the end of the fixing sleeve 1210 near the pull base 1208. The other end of the spring 1211 is fixedly installed to the plug plate 1201. The advantage is that, through the design of the spring 1211, it can be spring-loaded... Spring 1211 pushes the fixing sleeve 1210 to drive the limiting post 1209 to insert into the limiting hole 1206 of the protection plate 1205, thereby locking the protection plate 1205. When unlocking, the pull base 1208 can be pulled to compress the spring 1211, causing the limiting post 1209 to disengage and unlock the protection plate 1205. This allows for quick locking and unlocking, avoids accidental switch activation, and forms a double anti-accidental activation mechanism to prevent non-professionals from opening the protection plate 1205 at will. The unlocking operation is simple and does not affect maintenance efficiency.

[0028] Specifically, the end of the limiting post 1209 away from the pull seat 1208 has a groove 1212. The groove 1212 has a triangular cross-section. The advantage is that the triangular inclined surface can guide the limiting post 1209 to automatically align with the limiting hole 1206 during the sliding process of the protective plate 1205, reducing the alignment deviation and facilitating quick locking.

[0029] Specifically, the integrated circuit breaker 1 has handles 2 and mounting frames 3 fixedly installed at both ends. A positioning bolt 9 is inserted into the end of the control handle 6 near the connecting sleeve 8. A through hole 13 is opened at one end of the control handle 6. The positioning bolt 9 passes through the through hole 13 and extends into the interior of the connecting sleeve 8. The advantage is that the handle 2 provides a convenient carrying fulcrum, the mounting frame 3 ensures that the circuit breaker is firmly installed on the column, and the positioning bolt 9 restricts the rotation of the control handle 6 to prevent the circuit breaker from malfunctioning due to unauthorized operation. This can form a variety of anti-misoperation protection structures, and different protection structures can be selected according to different situations, thereby improving the overall practicality.

[0030] Working principle: During use, the slot 10 cooperates with the insert plate 1201. When installing the insert plate 1201, it can be inserted into the slot 10. The "L"-shaped structure restricts the horizontal movement of the insert plate 1201 and prevents vertical shaking, facilitating quick fixation and preventing misalignment during subsequent fixation. After the slot 10 and the insert plate 1201 are aligned, the positioning bolt 11 passes through the mounting hole 1203 of the positioning plate 1202 and is threaded to the integrated circuit breaker 1, allowing the positioning plate 1202 to be installed at the front end of the integrated circuit breaker 1. This facilitates the subsequent protection of the control handle 6. The design of the limiting groove 1204 guides the protection plate 1205 to slide along a fixed track. When closed, it completely covers the control seat 4 and the connecting seat 5, preventing accidental contact by personnel. When operation is required, the fixing parts can be unlocked to expose the control components, preventing accidental activation of the control switch during handling or movement. The design of the spring 1211 can... Spring 1211 pushes the fixing sleeve 1210 to drive the limiting post 1209 into the limiting hole 1206 of the protection plate 1205, thus locking the protection plate 1205. When unlocking, the pull base 1208 can be pulled to compress the spring 1211, causing the limiting post 1209 to disengage and unlocking the protection plate 1205. This facilitates quick locking and unlocking, avoids accidental switch activation, and forms a dual anti-accidental activation mechanism to prevent unauthorized personnel from opening the protection plate 1205. The unlocking operation is simple and does not affect maintenance efficiency. The triangular inclined plane guides the limiting post 1209 to automatically align with the limiting hole 1206 during the sliding process of the protection plate 1205, reducing alignment deviation and facilitating quick locking. The handle 2 provides a convenient carrying fulcrum, and the mounting frame 3 ensures that the circuit breaker is firmly installed on the post. The positioning bolt 9 restricts the rotation of the control handle 6, preventing circuit breaker malfunction caused by unauthorized operation. Multiple anti-accidental activation protection structures can be formed, and different protection structures can be selected according to different situations, thereby improving overall practicality.

[0031] 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.
