Switchgear Structure:
1. Switchgear is composed of cubicle and removable parts (so called trolley). The cubicle is separated into several functional compartments by metal sheet, including busbar compartment, circuit breaker compartment, cable compartment and low voltage
2. Switchgear removable parts can be equipped with VCB trolley, voltage transformer trolley, lightning arrester trolley and fuse trolley.
3. Pressure relief devices are installed above trolley compartment, busbar compartment and cable compartment. Special sealing ring on the door seals the panel door.
4. In case of faults inside the compartments resulting in arc, the pressure is going up inside the switchgear and the pressure relief equipped on the top will open automatically, to release pressure and high temperature gas. In this way, it can ensure the safety of operating staff and the switchgear.
