How do circuit breakers achieve locking?
How can the connection between two circuit breakers be closed and
not closed at the same time?
A method of mechanical interlocking. Low voltage circuit breakers
are generally available with interlock accessories (connected by
steel cables in the middle), and high voltage generally adopts
program locks.
Another method is electrical interlocking, that is, the normally
closed contact of another circuit breaker is connected in the
circuit of circuit breaker so that the circuit breaker cannot be
closed. The drawback of this method is that it cannot prevent
manual closing.
Safety lock equipment is a kind of planned safety protection
equipment to prevent the accidental opening. Many industrial safety
accidents can be avoided by adopting appropriate safety/lock
equipment.
