This circuit breaker is a 1-Trip circuit breaker used in 22.9kV overhead distribution lines,and the breaking capacity has been increased to 12.5kA in order to fundamentally prevent line spillage caused by high voltage customer equipment failure.

The body part is more eco-friendly by applying an epoxy mold insulation method instead of SF6 gas,and maintenance is not required due to gas leakage or replenishment. Due to the excellent insulation performance of epoxy,it can be applied not only to general areas but also to areas that are salty and contaminated,and stainless steel that is resistant to corrosion is used for the main body tank and control box.

It is a new product for automation that uses the Spring Charging method as an operation method and can adopt simple open/close control method or FRTU integrated digital control method. Performance has been verified by an international testing and certification organization according to the standards of KEPCO.

responsibility

-Internal vacuum cut-off method adopted

safety

-Prevents three-phase short circuit accidents with separate structure for each phase

-Resolve the risk of explosion of high pressure tank in SF6 gas insulation method

Environmentally friendly epoxy insulation

-It can be applied to damaged areas due to the use of epoxy bushings that are resistant to contaminated environments.

-Maintenance-free structure that does not require gas and pressure release locking device [Maintenance Free]

Other technical notes

-By applying multi-function control function,it is possible to save operation information and fault current waveform [1Cycle/128 Sample] for both power supply side and load side.

-Line power quality monitoring control PQM waveform can be saved
