A bypass switch, also known as a by-pass switch, is a mechanical power switching device connected across the DC terminals of one or more converter stations. It is applied in multiple fields such as power systems, data centers, industrial equipment, and satellite power supplies. This device is mainly used to connect or disconnect converter bridges, or to transfer loads to maintain power supply during line equipment maintenance or faults. In the field of high-voltage direct current (HVDC) transmission, high-performance products are required to have capabilities such as fast closing (e.g., ≤25ms), high insulation withstand voltage (e.g., 1050kV/1min), and large DC current transfer (e.g., DC3500A). In distribution systems, it is used in bypass operation methods to replace line switches without power outage. In Automatic Transfer Switch (ATS) systems, the bypass switch allows uninterrupted power supply to critical loads during ATS maintenance.
The core function of a bypass switch is to maintain power supply or system operation without interruption by switching paths during equipment maintenance or faults, and to achieve current shunting and equipment protection. It is widely used in power systems, data centers, industrial control, and other fields, serving as a key device for ensuring the continuity of critical loads.
Ensuring power supply continuity: When main line switches, circuit breakers, UPS, or other equipment require planned maintenance or experience faults, the bypass switch closes to transfer loads to the bypass circuit, ensuring no power outage for users or loads.
Equipment protection and isolation: In HVDC transmission or series compensation devices, it is used to connect or disconnect converter bridges, or to quickly shunt current during faults to protect main equipment from damage.
System operation control: It supports bypassing shutdown conditions (e.g., instrument calibration) in specific processes to maintain system operation, or achieving zero-switching-time access of backup power supplies.
Power transmission and distribution: Used in converter stations of HVDC transmission systems and in comprehensive live-line bypass operations of distribution networks.
Data centers and critical facilities: In Class A computer rooms, hospitals, banks, and other places, it cooperates with ATS systems or UPS to ensure stable power supply to critical equipment during maintenance.
Rail transit and industry: In vehicle circuits, it is used to bypass faulty original circuits to maintain train operation capability; in industrial processes, it is used to bypass specific detection conditions.
