Static contacts are mainly used in high-voltage switch cabinets, but not low-voltage.
The static contacts are installed in the contact box of the switch cabinet, 6 in a switch cabinet, 2 in each of the ABC three-phase and one-phase. A high-voltage connection through a circuit breaker is similar to the principle of the air circuit breaker we usually use. Take Phase A as an example. The incoming power passes through the A-phase busbar-the circuit breaker A-phase up-A-phase down, and then goes out.
There are two moving contacts for each of the three phases of ABC on the circuit breaker. The moving contacts and static contacts are the same as the pens and pen caps we use, just inserted, but the insertion distance is greater than or equal to 15mm.
