Power system:

Small dc circuit breaker in the power plants, substations and other large capacity, high voltage, dc system for relay protection in power system, operation control, signal and emergency lighting audio equipment to provide reliable power supply, dc circuit breaker as one of the important components of dc system, its stable and reliable operation directly will guarantee the safety of the power system

DC power supply:

With the vigorous development of the information industry ushered in the communication power supply, EPS, UPS and dc power supply industry big development, the base station, data centers appear like mushrooms in China, in order to guarantee high precision requirement of the dc power supply, as at every level of the dc power feed to operation and protection component in a circuit of dc circuit breaker, It plays a very important role in protecting equipment and limiting the scope of accident with its reliable selective classification.

Rail transit and electric locomotives

At present, China’s urban traffic (e.g. Light rail and subway, mu trains, running on the system of electric locomotive, etc.) adopt dc power supply system, and its most dc power supply is provided by high-power silicon rectifier device, low silicon rectifier device components due to the overload capacity, the higher request of dc electrical protection components, special fast breaking dc circuit breaker is an important component of rail transit.

Ships to:

DC circuit breaker is one of the most important components in the ship’s electric power system and electric propulsion system. It protects the faults of the power transformation and distribution system and electrical equipment, and takes various precautions to ensure the safety of the ship’s power supply system and electrical equipment.
