Description

FBM240-P0917GZ isolation switch is a switching device mainly used for "isolating power supply, switching operation, connecting and cutting off small current circuits". It has no arc extinguishing function and can only open and close when there is no load current. circuit. The main feature of FBM240-P0917GZ isolating switch is that it has no arc extinguishing ability and can only open and close circuits when there is no load current. When in the open position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within the specified time. Switchgear. In practical applications, the FBM240-P0917GZ isolating switch is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage above 1kV. Because its working principle and structure are relatively simple, but due to its large usage and high working reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. In addition, Delixi Electric's small isolating switch modular main switch DZ47G2P, Schneider Electric's Vario series load switch body + handle VCF01C, etc. are all common brands and models on the market.

The main features of the FBM240-P0917GZ isolation switch include: No arc extinguishing capability: The isolation switch can only open and close circuits when there is no load current, and cannot be used to disconnect load current. Simple structure, small size and light weight: Isolating switches generally have a relatively simple structure, small size and light weight, making them easy to install and maintain. Fast action: The contacts of the isolating switch generally use sliding contacts, which have fast action speed and can quickly open and close circuits. High reliability: The use environment of the isolating switch is relatively simple, and generally does not require particularly complex mechanical structures and control systems, so the reliability is high. Lower price: Since the structure of the isolating switch is relatively simple and the manufacturing cost is low, the price is also relatively low. In general, the isolating switch is a simple, reliable, and practical switching device that is widely used in power systems.
