Primary And Secondary Deep Integration Built-In Isolation Type Pole Mounted Circuit Breaker

1. Product structure and design
Integrated design:
The pole-mounted circuit breaker, built-in isolating knife switch and current sensor adopt an integral cast sealed column design, with a modular appearance and a sturdy and stable structure.
The protection conditions of high-voltage components and transmission systems are comprehensively improved, and the sealing performance is excellent.

Main circuit composition:
The main circuit includes: upper outlet, vacuum arc extinguishing chamber, soft connection, plug-in built-in isolating knife switch, plum blossom contact finger and lower outlet.

Built-in isolating knife switch:
It adopts a cylindrical columnar structure, which is realized by integrally casting a sealed column.
All high-voltage primary circuit conductive and transmission insulation components are designed in the inner cavity of the cylinder, and only the lower outlet connector is exposed outside the cylinder.
The silicone umbrella skirt design increases the external creepage distance and provides higher safety.

2. Core functions
Built-in isolation function:
The built-in isolating knife switch adopts a plug-in design, which is easy to operate and highly reliable.
The isolating knife switch and circuit breaker are integrated to reduce external connection points and reduce the failure rate.

Deep integration of primary and secondary equipment:
The primary equipment (circuit breaker, isolating knife switch) and secondary equipment (sensor, controller) are deeply integrated to realize the intelligentization of data acquisition, transmission and control.
Support real-time monitoring and remote operation of distribution automation system.

3. Technical features
