LW□-12 Primary and Secondary Integrated SF₆ Circuit Breaker

 Main structural features

 LW□-12 Primary and Secondary Integrated SF₆ Circuit Breaker, which uses the magnetic field force received by the arc current to make the arc rotate at high speed along a certain section. Due to the relatively light weight of the arc, it gradually elongates and continuously contacts fresh SF6 gas during high-speed rotation, and is cooled and extinguished. This type of circuit breaker has the advantages of strong arc extinguishing ability, long electrical life, no current interruption when breaking small currents, and no overvoltage during operation. At the same time, it requires less operating power and has high reliability.

 The circuit breaker adopts a miniaturized spring operated mechanism, which has the advantages of reliable operation, long mechanical life, and simple control. The spring operated mechanism can store energy manually or electrically, open and close manually or electrically, and has a reclosing function.

 The material of the circuit breaker box is made of 3mm thick 304 stainless steel welded together, with a fully airtight structure and a protection level of not less than IP67; There are easily observable and obvious opening and closing position indicators and energy storage status indicators on the box, which are reliably connected to the operating mechanism and have reliable indication actions. The box has a handling handle to avoid pulling the wire conduit.
