Boundary switch

111

As a demarcation switch, it can realize independent and rapid protection and isolation of user internal faults without cooperating with upper-level switches or substation switches, reduce the scope of power outages, and ensure the safety of power supply in non-faulty areas.

Segment switch

111

As a sectional switch, it cooperates with the substation to identify the faulty area and isolate it quickly, and reliably restore the power supply to the non-faulty area.

Contact switch

111

As a tie switch, it can realize "hand in hand" ring network power supply, reduce the scope and time of power outages, and improve the reliability of power supply.

Self-cast protection switch

111

As a protection switch for standby and self-switching equipment, it is used in power systems and factories with dual power incoming lines, one main and one standby, without segmented operation. When the normal power supply line is faulty or the power supply itself has an accident and the power is cut off manually , automatically and quickly switch to the backup power supply to ensure the normal operation of the user terminal and minimize the economic loss of power outages.
