Description

Technical Field

[0001] The present application relates to the technical field of circuit breakers, and in particular to a primary-secondary integrated pole-mounted circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] In the patent with the published authorization announcement number CN214672430U, the primary and secondary integrated pole-mounted circuit breaker includes a mechanism box, an arc extinguishing chamber and a mounting seat, the top of the mechanism box is fixedly connected with an anti-slip structure; one end of the arc extinguishing chamber is fixedly connected with a current transformer; both sides of the bottom end of the mounting seat are fixedly connected with a mounting structure, the bottom end of the inner side wall of the mounting seat is fixedly connected with a reinforcement structure, the reinforcement structure includes a positioning hole, a retaining ring and a positioning rod, the outer side wall of the positioning hole is fixedly connected to the inside of the bottom end of the mechanism box, and the inner side wall of the positioning hole is fixedly connected with a retaining ring. The utility model is provided with a reinforcement structure, because the arc-shaped retaining piece is an arc-shaped umbrella-shaped structure, when the mechanism box is vertically inserted into the interior of the mounting seat, the positioning rod above the mounting seat will be inserted into the interior of the positioning hole, at this time, the arc-shaped retaining piece is opened under the action of its own elastic force and is held by the retaining ring, so that the mechanism box is difficult to lift from the inside of the mounting seat, thereby realizing the connection reinforcement between the mechanism box and the mounting seat.

[0004] When the above device is implemented, the connection between the mechanism box and the arc extinguishing chamber is too fixed. Since the device is usually installed in an outdoor location, the staff needs to frequently inspect and maintain it. In addition, the arc extinguishing chambers are usually grouped into three. The overly fixed structure may cause one of them to be damaged, and the other two are not easy to disassemble and can only be scrapped together, which is not conducive to promotion and use.

[0013] As a preferred embodiment, a connecting hole is opened at the inner bottom of the mounting block, and the connecting hole passes through the mounting block and the mounting plate, and the bolt is arranged on the inner wall of the connecting hole.

[0014] By adopting the above technical solution, the mounting plate and the mounting frame can be fixedly connected by using bolts in conjunction with the connecting holes, thereby ensuring the stability of the connection.

[0015] As a preferred implementation, a rotating ring is fixedly mounted on a side of the limiting plate away from the connecting rod, and the distance between the side of the limiting plate away from the rotating ring and the equipment box is consistent with the thickness of the slider.

[0016] By adopting the above technical solution, the rotating ring is used to increase the convenience of rotating and pulling the connecting rod, thereby facilitating the installation and disassembly of the connecting rod.
