Low-voltage system power distribution and central control

The low-voltage system power distribution cabinet consists of distribution substation (generally reducing the transmission voltage of the power grid to the distribution voltage), high-voltage distribution lines (that is, voltages above 1 kV), distribution transformers, and low-voltage distribution lines (1 thousand The voltage below volts) and the corresponding control protection device.

Low-voltage circuit breaker: Low-voltage circuit breaker, also known as automatic switch, is an electrical appliance that has both manual switching effect and automatic voltage loss, undervoltage, overload, and short-circuit protection. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically block circuits when they are severely overloaded or short-circuited or under-voltage. Their functions are equivalent to fuse switches and A combination of under-heat relays, etc. And after breaking the fault current, there is generally no need to change the parts, and one has obtained a wide range of applications.

(1) Circuit breaker accessories

(2) Miniature circuit breaker: miniature circuit breaker, referred to as MCB, is a kind of terminal protection appliance widely used in building electrical terminal power distribution equipment.

(3) Molded case circuit breaker: Molded case circuit breaker can automatically block the current after the current exceeds the trip setting. Molded case refers to the use of plastic insulators as the outer casing of the device to block the conductors and the grounded metal parts. Molded case circuit breakers typically contain a thermal magnetic trip unit, while large types of molded case circuit breakers are equipped with solid state trip sensors.
