0 flashover (no arcing shield) is basically realized by using double row compound contact/horizontal pull mechanism/micro-motor pre-storage and micro-electronic control technology.
Reliable mechanical interlock and electrical interlock are adopted, and independent load isolation switch is adopted for actuating components to ensure safe and reliable operation.
Adopting 0-crossing technology, it can be forced to 0 in emergency (cut off two power sources at the same time) to meet the needs of fire linkage; The switch of load isolation switch is driven by a single motor. The switch is reliable, stable, noiseless and has little impact force.
The driver motor of the operator only passes the current at the moment when the load isolation switch is switched, which saves energy significantly.
Carry out load isolation switch with mechanical interlock device to gurantee that common and standby power supply work reliably without interference.
