Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and in particular relates to a deep integration of primary and secondary intelligent pole-mounted circuit breakers. Background Technology

[0002] The deeply integrated primary and secondary intelligent pole-mounted circuit breaker is a core device for the intelligent upgrade of 10kV distribution networks. Through deep integration design, it breaks down the traditional boundaries between primary and secondary equipment, integrating the circuit breaker body (primary equipment) responsible for power switching with feeder terminals (FTUs), electronic sensors, communication modules, and other components (secondary equipment) responsible for monitoring, protection, and control into a single unit. It employs reliable technologies such as vacuum arc extinguishing to ensure circuit switching and fault interruption capabilities. Simultaneously, it integrates high-precision current and voltage acquisition, fault transient waveform recording, and other functions. Utilizing edge computing and standardized communication protocols (such as IEC61850), it achieves real-time data interaction. It supports remote monitoring and remote control operation, and can also quickly handle short circuits, grounding faults, etc., through local automation functions when there is no master station or communication is poor. The fault location error can be controlled within 150 meters, and the shortest overall action time is only 40ms. This highly integrated design not only simplifies the equipment architecture and installation process, and reduces operation and maintenance costs and failure rates, but also improves the reliability and intelligence of the power distribution network through advanced functions such as fault self-healing and load optimization, providing key support for the construction of new power systems.

[0003] After inserting the bolt into the terminal block of the primary and secondary integrated intelligent pole-mounted circuit breaker, the bolt needs to be supported until the nut is installed before it can be loosened. Otherwise, the bolt may fall downwards. The bolt's position needs to be maintained throughout the installation process until the nut is installed, which makes the installation of the terminal block of the conventional primary and secondary integrated intelligent pole-mounted circuit breaker quite troublesome.

[0004] To address these issues, we propose a deep integration of primary and secondary intelligent pole-mounted circuit breakers. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of complicated installation of wiring terminals in conventional deep integration intelligent pole-mounted circuit breakers, and proposes a deep integration intelligent pole-mounted circuit breaker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The primary and secondary integrated intelligent pole-mounted circuit breaker includes a circuit breaker body with terminals installed on it. Bolts are inserted inside the terminals, and a fixed shaft is fixedly connected to the lower end of each terminal. A baffle is movably fitted onto the fixed shaft, and a spring is fitted onto the lower part of the fixed shaft. The lower end of the spring is fixedly connected to the fixed shaft, and the upper end of the spring is in movable contact with the baffle. The baffle presses against the lower end of the bolt. The spring force acts upward on the baffle, which in turn acts upward on the bolt, keeping the bolt within the terminal. Rotating the baffle removes the bolt, allowing a new bolt to be inserted. Screwing the baffle onto the lower end of the new bolt facilitates keeping the bolt within the terminal of the circuit breaker body and also facilitates bolt replacement.

[0007] Preferably, the terminal includes a contact piece with a hollowed-out mounting hole, the bolt being inserted into the mounting hole, and the contact piece being electrically connected to the circuit breaker body.

[0008] Preferably, the terminal further includes a rotation limiter, which contacts the bolt's knob. The rotation limiter blocks the hexagonal knob of the bolt, preventing rotation and facilitating the tightening of the target nut.

[0009] Preferably, the fixed shaft includes a shaft body, a retaining ring fixedly connected to the lower end of the shaft body, and a contact plate fixedly connected to the upper end of the shaft body. A spring is movably sleeved outside the shaft body, and the lower end of the spring is fixedly connected to the retaining ring. The shaft body guides the movement of the retaining plate.

[0010] Preferably, the baffle includes a sheet body with a through hole in the middle, and the shaft body is movably inserted into the through hole. The shaft body guides the movement of the sheet body.

[0011] Preferably, the baffle further includes a movable sleeve, which is movably fitted onto the shaft. The movable sleeve increases the range of contact between the baffle and the fixed shaft, thereby increasing the stability of the baffle.

[0012] In summary, the technical effects and advantages of this utility model are as follows: The spring force acts upward on the baffle plate, which in turn acts upward on the bolt, keeping the bolt inside the terminal. Rotating the baffle plate removes the bolt, allowing a new bolt to be inserted. Tightening the baffle plate to the lower end of the new bolt facilitates keeping the bolt inside the terminal of the circuit breaker body and also makes bolt replacement easier.

The lower end of the spring 5 is fixedly connected to the fixed shaft 3, and the upper end of the spring 5 is in movable contact with the baffle 4. The baffle 4 presses against the lower end of the bolt 6. The spring force of the spring 5 acts upward on the baffle 4, which in turn acts upward on the bolt 6, keeping the bolt 6 inside the terminal block 2. By rotating the baffle 4, the bolt 6 can be removed, a new bolt 6 can be inserted, and the baffle 4 can be screwed onto the lower end of the new bolt 6.

[0018] like Figure 1 and 2 As shown, terminal 2 also includes a rotation limiter 22, which contacts the knob of bolt 6. The rotation limiter 22 blocks the hexagonal knob of bolt 6, preventing bolt 6 from rotating.

A spring 5 is movably sleeved outside the shaft body 31, and the lower end of the spring 5 is fixedly connected to the retaining ring 32. The shaft body 31 guides the movement of the retaining plate 4.

[0020] like Figure 1 , 3 As shown in Figure 4, the baffle 4 includes a plate 41, with a through hole 42 hollowed out in the middle of the plate 41, and a shaft 31 is movably inserted into the through hole 42. The shaft 31 guides the movement of the plate 41.

[0021] like Figure 1 , 3 As shown in Figure 4, the baffle 4 also includes a movable sleeve 43, which is movably fitted onto the shaft 31. The movable sleeve 43 increases the range of contact between the baffle 4 and the fixed shaft 3, thereby increasing the stability of the baffle 4.

[0022] Working principle: The spring force of spring 5 acts upward on the baffle 4, and the baffle 4 acts upward on the bolt 6, keeping the bolt 6 inside the terminal 2. Rotate the baffle 4 to remove the bolt 6, replace it with a new bolt 6, and screw the baffle 4 to the lower end of the new bolt 6.
