Morethe safety of
circuit is one of the most important things in our life. before leaving home, we must check whether the circuit in our home is closed or not. now there must be circuit breakers, which saves a lot of attention. circuit breaker can quickly cut off the power supply to protect the circuit when the circuit breaks down. before purchasing circuit breakers,
must make clear the classification of circuit breakers, so that it will not be very entangled when purchasing. here are some common circuit breakers in life.
1, small circuit breaker
small circuit breaker is mainly used in household circuits, with advanced structure, reliable performance, strong breaking ability, beautiful and compact appearance and so on. it adopts industrial distribution system. when the circuit is short-circuit or overloaded, it will automatically turn on the protection switch and cut off the power supply, thus protecting the safety of household appliances. it can also be used as a circuit for less frequent on-off operation and conversion.
2, surge protector
surge protector is a powerful circuit breaker, also known as lightning protector. it is a kind of electronic equipment which provides safety protection for various electronic devices, instruments and communication lines. it is used to protect circuit breakers from overvoltage caused by indirect lightning or direct lightning. when the spike current or voltage suddenly occurs in the electrical circuit or communication line due to external interference, the surge protector can conduct shunt in a very short time, thus avoiding the harm of surge to other equipment.
3, ac contactor
ac contactor mainly provides long-distance switching-on and disconnecting circuit, which can make immediate protection when the remote circuit is in trouble. its working principle is to use electromagnetic force and spring elastic force to cooperate to realize the connection and separation of contacts.
4, universal intelligent circuit breaker
universal intelligent circuit breaker, also known as frame circuit breaker, is mainly used to distribute electric energy and protect circuit. when the circuit has overload, short circuit, under voltage and other faults, it can immediately make protective measures. universal circuit breaker is suitable for 50 hz ac, rated voltage 380 v, 660 v, rated current 200 a-6300a distribution network. circuit breaker is three-dimensional layout, contact system. instantaneous over-current tripper's left and right side plates are installed on an insulating board, and arc extinguishing system is installed on the upper part. the operation mechanism can be installed in the front or right side. intelligent circuit breaker has a variety of intelligent protection functions, which can achieve selective protection, accurate action, avoid power outages, improve the reliability of power supply and other advantages, and can be used as a non-frequent conversion of lines.
