Circuit Breaker as a switch device that can switch on, carry and break the current under normal circuit conditions, and can also switch on and carry a certain time and break the current under specified abnormal circuit conditions, is an indispensable part of the power system. Its main function is to turn on, carry and break current under normal or abnormal loop conditions. This switching device can automatically cut off the circuit within a specified time to prevent equipment damage or fire caused by circuit overload, short circuit, undervoltage and other faults. The circuit breaker combines the functions of the fuse switch and the over-under-heat relay, which can act quickly when abnormal current is detected to protect the safety of the circuit and electrical equipment.
Application
As an important protection equipment in the power system, the circuit breaker not only ensures the stable operation of the power grid, but also protects the safety of the circuit and electrical equipment. In addition, circuit breakers also play a very critical role in other areas, such as in building electrical systems, used to protect circuits and electrical equipment from current overload; In industrial equipment, it is used to control various motors and electrical equipment on the production line to ensure that the equipment is protected during normal operation, and at the same time, the power is quickly cut off in the event of failure to prevent equipment damage and production interruption; With the development of smart grids and renewable energy, circuit breakers are constantly evolving. The intelligent circuit breaker integrates electronic technology and communication technology, which can realize remote control and monitoring, and improve the intelligent level of the power system. In microgrid, solar photovoltaic and other fields, solid circuit breakers have been widely used because of their environmental protection, miniaturization and high reliability.
What is a TVS diode and its benefits?
What is a TVS diode? TVS diode, also known as transient voltage suppression diode, is an electronic part for protection that can protect electrical equipment from voltage spikes introduced by wires. Overvoltage protection devices with two-way voltage stabilization and two-way negative resistance characteristics are similar to varistors.
What is the function of surge suppression IC?
What is a surge suppression IC? Surge suppression IC is an electronic device used to protect electronic equipment, instruments and communication lines from surge voltage or current. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference,
What is a Thermal Cutoff or Thermal Fuse?
What is a Thermal Cutoff? A thermal cutoff (also known as a temperature fuse) is a non-resettable disposable thermal protection device that cuts off the temperature sensing circuit. Mainly used for overheating protection in electrical circuits.
What is a Ground Fault Circuit Interrupter (GFCI)?
What is a ground fault circuit interrupter? A GFCI is used to detect and prevent ground faults. A ground fault is an accidental current flow to the ground through the human body or other paths, which may result in electric shock injury.
