GW8-126 Outdoor disconnector of neutral point 126kv
GW8-126 isolation switch is mainly composed of isolation switch, main connecting rod system and operating mechanism. The body is composed of contact assembly, rod type pillar insulator, conductive rod assembly, bag plate, etc. The connecting rod system is composed of a joint and a connecting rod. The output shaft of the operating mechanism can be rotated 120 horizontally. Through the connecting rod system and the crank arm, the moving contact and the static contact are rotated to close or open. When in the closing or opening position, the positioning device on the operating mechanism ensures that the moving contact and the static contact are in the correct closing or opening position.
It is an important equipment widely used in power systems, mainly used to isolate the power supply, switch the circuit and provide an obvious disconnect point during maintenance, so as to ensure the safe operation of the power system. The isolation switch is suitable for the rated voltage 126kV, rated current 630A power system, has the advantages of compact structure, flexible operation and easy maintenance.
GW8-126 isolation switch adopts the patch-type structure, covers a small area, the rotating part is designed according to the requirements of maintenance-free, the use of stainless steel shaft pin and oil-free self-lubricating bearing matching structure, the overall steel parts are hot-dip galvanized treatment, to ensure flexible operation, lightweight, reliable, no rusting.
