The Use of High-Voltage Disconnect Switches

Yunfeng Technology's high-voltage isolating switches are widely used switching devices in high-voltage current systems, serving as critical isolation components in electrical circuits. Although their operating principle and structural design are relatively simple, they play an indispensable role in everyday applications—and significantly influence the design and construction of substations and power plants, as well as the efficient operation of power facilities. Yunfeng's high-voltage isolating switches are available in standard specifications such as 12kV, 24kV, and 40.5kV.

Main Structure of High-Voltage Circuit Breakers

Yunfeng Technology boasts a wide range of modern manufacturing and processing equipment, along with various testing instruments tailored to meet industry demands. With strong corporate capabilities, the high-voltage circuit breakers can not only switch off or connect no-load currents and load currents in high-voltage circuits but also, in the event of a system fault, automatically trip to cut off overcurrents and short-circuit currents thanks to the relay protection system. These breakers feature a highly advanced arc-extinguishing design and deliver robust breaking capacity, ensuring reliable performance even under demanding conditions.

Precautions for High-Voltage Load Switches

The Yunfeng high-voltage load switch is an electrical device that functions somewhere between a high-voltage circuit breaker and a high-voltage isolator. It is often used in conjunction with high-voltage fuses in series to control power transformers. The high-voltage load switch features a simple arc-extinguishing mechanism, enabling it to handle and interrupt both normal load currents and overload currents. However, it cannot break short-circuit currents; therefore, it is typically installed in series with high-voltage fuses, relying on the fuses for effective short-circuit protection.

Precautions for Using High-Voltage Load Switches

Yunfeng Technology's high-voltage load switch is primarily used to control power transformers, serving a function that falls between a high-voltage circuit breaker and a high-voltage isolating switch. Since the high-voltage load switch cannot interrupt short-circuit currents, it is typically used in series with a high-voltage fuse to provide short-circuit protection. This switch boasts advantages such as compact size, excellent safety performance, lightweight design, and long service life.
