Switchgear Structure:
1. The switchgear is installed electrical indication device in primary circuit. The device includes high voltage sensors and an indicator, and can indicate high voltage circuit electrical status.
2. It can also cooperate with electromagnetic lock to conduct compulsory latching on operating handle, cubicle door and adjacent cubicles. Thus, it can prevent from withdrawing isolation trolley with loads, prevent earthing switch from energized closing, and prevent from entrance of energized compartment. In this way, it can increase prevention performance of the equipped products.
3. In order to prevent condensation in high humidity or dramatically changed temperature environment, electrical heater is installed separately in circuit breaker compartment and cable compartment, to avoid dielectric accidents in the above conditions.
4. Cable compartment installs additionally earthing copper busbar which goes through adjacent cubicles and with good connection to cubicles. The copper busbar is used for direct earthing components. Since the whole cubicle is joint by aluminum zinc coated steel plates, the cubicle is in good earthing status, thus ensuring safety of operating staff.
