Electrical explosion proof switch disconnect  , emergency stop circuit breaker






The circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a trip unit, a casing, and the like.

When short-circuited, the magnetic field generated by a large current (generally 10 to 12 times) overcomes the reaction force spring, the trip unit pulls the operating mechanism, and the switch instantaneously trips. When overloaded, the current becomes larger, the heat is increased, and the bimetal is deformed to a certain extent to push the mechanism (the larger the current, the shorter the action time).

If there is an electronic type, the current of each phase is collected by using a transformer, and compared with the set value, when the current is abnormal, the microprocessor sends a signal to cause the electronic trip unit to drive the operating mechanism.

The function of the circuit breaker is to cut off and close the load circuit, and cut off the fault circuit to prevent accidents from expanding and ensure safe operation. The high-voltage circuit breaker is to break 1500V, the current is 1500-2000A arc, these arcs can be extended to 2m and continue to burn without extinguishing. Therefore, arc extinguishing is a problem that must be solved by high voltage circuit breakers.

The principle of arc-extinguishing arc is mainly to cool the arc to attenuate the heat release. On the other hand, the arc is used to stretch the arc to enhance the recombination and diffusion of the charged particles, and at the same time, the charged particles in the arc gap are blown off, and the dielectric strength of the medium is quickly restored.

Low-voltage circuit breakers, also known as automatic air switches, can be used to switch the load circuit on and off, as well as to control motors that are not frequently started. Its function is equivalent to the sum of all or all of the functions of the knife switch, over current relay, voltage loss relay, thermal relay and leakage protector. It is an important protection device in the low voltage distribution network.
