RH-B Series Combination Electrical Fuse Type Isolation Switch

Combination electrical -fuse type isolation switch is a simple and effective manually operated protective device,mainly used for
solating circuits or short circuit protection in circuits.
lsolation switch is a switch device mainly used for isolating power supply,switching operation,connecting and cuting off small curent circuits,without arc extinguishing function.When the isolation switch is in the open position,there is an insulation distance andobvious disconnection mark between the contacts that meets the specified requirements;A switchgear that can withstand the current under normal circuit conditions and the current under abnormal conditions (such as short circuits)within a specified time when in the closed position.It is generally used as a high-voltage isolation switch,that is,an isolation switch with a rated voltage of 1kV or above.Its working principle and structure are relatively simple,but due to its large usage and high reliability requirements,it has a significant impact on the design,establishment,and safe operation of substations and power plants.The main characteristic of isolation switches is that they have no arc extinguishing ability and can only open and close circuits without load current.The entry introduces the functions,characteristics,types,applications,error prevention improvements,maintenance,and common problems of isolation switches.
