Description

Technical Field

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

[0002] The primary and secondary integrated pole-mounted circuit breaker is an advanced power equipment that integrates industry-leading technologies such as electronic voltage sensors, electronic current sensors, power metering modules, and high-speed fault transient recording. This equipment typically consists of core components including a vacuum circuit breaker body, feeder unit (FTU), power voltage transformer, solid-sealed poles, and connecting cables. For the insulation housing, the primary and secondary integrated pole-mounted circuit breaker is usually made of elastic materials such as rubber, epoxy resin, nylon fiberglass, or PC. These materials give the insulation housing good deformability, making it less prone to breakage during electrohydraulic effects. The main function of the insulation housing is to isolate conductors with different potentials, prevent the generation and spread of electric arcs, thereby ensuring the reliable operation of the circuit breaker.

[0003] In practical applications, the installation of the insulation shell of a primary and secondary integrated pole-mounted circuit breaker typically involves using fasteners to secure each component within the shell. During installation, to ensure each component is accurately positioned and secured with fasteners, operators must possess a high level of expertise and precision. The use of fasteners increases the complexity and time-consuming nature of the installation process, as each fastener needs to be tightened individually to guarantee the stability and safety of the components.

[0004] During maintenance, if components inside the insulation housing need to be disassembled for inspection or repair, operators must loosen the fasteners one by one. This not only increases the tediousness of the operation but also may cause damage or loss of fasteners due to improper operation. In addition, if the components inside the insulation housing are arranged compactly, the disassembly and reinstallation process will be more difficult and may even require the use of special tools or equipment. Utility Model Content

[0005] The main objective of this invention is to provide an insulating shell structure for a primary and secondary integrated pole-mounted circuit breaker, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An insulating housing structure for a primary and secondary integrated pole-mounted circuit breaker includes a bottom bracket and a side bracket, wherein the side bracket is installed on the side wall of the bottom bracket;

[0008] An insulating protective shell is installed at the upper end of the bottom bracket, which protects the primary and secondary integrated pole-mounted circuit breaker assembly.

[0009] The insulating protective shell includes a protective shell, a side connector, and protrusions. Multiple protective shells are installed on the upper end of the bottom bracket, and the side connectors are installed on the side walls of the protective shells. The protrusions are distributed at the upper and lower ends of the protective shells.

[0010] The lower end of the protective housing is provided with an installation cavity, and the cavity wall of the installation cavity is provided with a limiting protrusion. An arc-shaped installation bracket is inserted and connected to the limiting protrusion of the installation cavity, and a limiting groove adapted to the limiting protrusion is provided on the arc-shaped installation bracket. The arc-shaped installation bracket enables the rapid installation of the primary and secondary integrated pole-mounted circuit breaker assembly.

[0011] As an optional solution of this utility model, the side wall of the arc-shaped mounting bracket is provided with a plurality of lateral arc-shaped strips, which are equidistantly distributed on the arc-shaped mounting bracket. The end faces of the arc-shaped mounting bracket and the lateral arc-shaped strips are provided with mounting holes, which are equidistantly distributed.

[0012] As an optional solution of this utility model, the lateral arc strip is a pair of elastic metal plates, the outer edge of the lateral arc strip is arc-shaped, and the lateral arc strip is welded and fixed on the arc mounting bracket. The lateral arc strip, the arc mounting bracket and the curvature of the protective shell are adapted.

[0013] As an optional solution of this utility model, the protective shell, the side pipe and the protrusion are designed as an integral part, and the protective shell and the limiting protrusion are designed as an integral part, and the connection between the protective shell and the limiting protrusion is arc-shaped.

[0014] As an optional solution of this utility model, the edge of the limiting groove is arc-shaped, and a round hole is opened in the groove of the limiting groove. The round hole is directly opposite the screw hole on the limiting protrusion and is fixed to the protective shell by bolts. The arc-shaped mounting bracket and the connection of the protective shell are provided with anti-slip strips.

[0015] As an optional solution of this utility model, the inner end face of the arc-shaped mounting bracket faces the lateral connecting pipe, and the lateral connecting pipe and the limiting protrusion are symmetrically distributed on the two quadrant points of the protective shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] As the primary protective component, the robust structure of the protective housing effectively protects the primary and secondary integrated pole-mounted circuit breaker assembly from damage caused by the external environment. The arc-shaped mounting bracket, through its limiting grooves, tightly engages with the limiting protrusions on the protective housing, further enhancing structural stability and ensuring that the circuit breaker assembly does not shake or shift during installation and use.

[0018] This design simplifies the installation process and improves efficiency. The curved mounting bracket allows the circuit breaker assembly to be quickly and accurately positioned in the mounting cavity, while the engagement of the limiting groove and the limiting protrusion ensures a secure installation. This rapid installation method not only saves time but also reduces the error rate during installation.

[0019] The protective housing is designed to match the curvature of the arc-shaped mounting bracket, which is not only aesthetically pleasing but also improves the structural compactness. This compact structure helps reduce space requirements, making the entire circuit breaker insulation housing structure smaller, lighter, and easier to transport and install.

[0020] This design also facilitates subsequent maintenance and repair. Because the arc-shaped mounting bracket and protective housing are structurally robust and easy to disassemble, relevant components can be easily removed when maintenance or repair of the circuit breaker assembly is required, reducing maintenance difficulty and cost.
