A high voltage DC relay is an electrical device used to control the current in a high voltage DC circuit. It usually consists of an electromagnet and a movable metal arm that moves and makes or breaks a circuit when the electromagnet is energized. HVDC relays are commonly used in power systems, such as DC transmission lines, power conversion stations, and power electronics equipment. They can control high voltages and high currents and are characterized by fast response, high reliability and long life. The HVDC relay market is a growing market primarily driven by demand from the power industry and industrial automation industries. With the continuous upgrading of power systems and the continuous development of power conversion technology, the demand for high-voltage DC relays is also increasing.
In the power industry, high-voltage DC relays are mainly used in fields such as DC transmission lines, power conversion stations, and power electronic equipment.
