Description

Technical Field

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

[0002] A pole-mounted circuit breaker has only one or two switches. The pole-mounted circuit breaker with integrated primary and secondary circuits has short-circuit fault and overvoltage protection functions. Its overcurrent protection is accomplished through a magnetic induction coil. It has complete maintenance functions and is easy to maintain. It is widely used in power supply systems. The existing pole-mounted circuit breaker with integrated primary and secondary circuits adopts magnetic control. The pole-mounted magnetic control circuit breaker with integrated primary and secondary circuits has the characteristics of high reliability, long life, small size, light weight, accurate and fast, no bounce when closing, and opening and closing operation according to phase angle.

[0003] The prior art patent application with publication number CN222190566U describes a method where pulling out a pull-out cover causes a guide rod to move on a mounting plate, a telescopic spring to retract, and two sliding blocks to move closer together. This causes the locking rods on the sliding blocks to move inward, inserting a support plate into the mounting plate and L-shaped support frame. Fastening bolts are then installed on the mounting plate, L-shaped support frame, and support plate. The fastening bolts and nuts are threaded together, improving the stability of the support plate and mounting plate. The nut is in the mounting groove and cannot loosen. A limit cap is threaded onto the threaded ring groove, and the fastening bolt is located inside the limit cap, restricting its movement and improving safety. Once the limit cap is installed on the threaded ring groove and the support plate is installed between the L-shaped support frame and the mounting plate, releasing the pull-out cover allows one end of one locking rod to engage with a locking hole on the limit ring, and the other end of the locking rod to engage with an assembly hole on the support plate, improving safety and stability.

[0004] However, in order to ensure stable installation, modern magnetic circuit breakers use a snap-fit ​​mechanism between the circuit breaker and the load-bearing plate. However, the current snap-fit ​​mechanism has a complex structure, and malfunctions during use can cause inconvenience in maintenance.

[0005] Therefore, it is necessary to provide a primary and secondary integrated pole-mounted magnetic circuit breaker to solve the above-mentioned technical problems. Utility Model Content
