Application Places Of DC Miniature Circuit Breakers

What are the applications of DC miniature circuit breakers in various places? Take TX7-63Z/1P DC circuit breaker as an example. The DC circuit breaker is suitable for AC 50Hz or 60Hz, rated voltage 230/400V and rated current to 63A and below as overload and short circuit protection for circuits, lighting and power equipment. , It can also make infrequent on-off switching of lines and equipment under normal conditions.

Power Systems:

DC miniature circuit breakers are used in large-capacity and high-voltage power systems such as power plants and substations. DC systems provide reliable power supplies for relay protection, operation control, signal and sound, and emergency lighting. DC circuit breakers are used as DC systems. One of the important components, its stable and reliable operation will directly ensure the safety of the entire power system

DC power supply:

With the vigorous development of the information industry ushered in the great development of the communication power supply, EPS UPS and other DC power supply industries. Base stations and data centers have sprung up on the land of China. In order to ensure the high precision requirements of DC power supplies, they are used as DC power supplies. The DC circuit breakers, which are required to operate and protect the components of the feeder circuits at all levels, play a very important role with their reliable selective and hierarchical cooperation with the protection equipment and limit the scope of the accident.

Rail transit and electric locomotives

At present, my country's urban transportation systems (such as subways, EMUs, light rails, and electric locomotives running on them) are powered by DC systems, and most of their DC power supplies are provided by high-power silicon rectifiers. The overload capacity is low, and the requirements for DC grid protection components are higher. The fast-breaking DC special circuit breaker is an important component in rail transit.

Ship:

In the ship's power system and electric propulsion system, the DC circuit breaker is one of the most important components. Safety of electrical equipment.
