The KJG-06 series isolation operating mechanism is suitable for the matching equipment for the operation of disconnectors and earthing switches in the internal isolation of inflation-type high-voltage ring main units. This series utilizes flat helical spring energy storage to control the closing and opening actions of the disconnectors, and compressed spring energy storage to control the closing and opening actions of the earthing switches. It features three operating positions: closing, opening, and grounding, and comes with a five-prevention interlock function.

This series of products is factory-certified after full inspection, complying with the requirements of GB 3804-2017 "AC High-Voltage Load Break Switches for 3.6kV-40.5kV," GB 3906-2020 "AC Metal-Enclosed Switchgear and Control Equipment for 3.6kV-40.5kV," "High-Voltage AC Load Break Switch-Fuse Combination Appliances," and GB/T 11022-2020 "Common Technical Requirements for Standards of High-Voltage AC Equipment and Control Equipment."

User Operation Instructions

Circuit closing operation:

After inspecting and confirming the product is normal and free of deformation, install the mechanism and isolating switch by aligning them through a three-position motion on the pressure box of the circuit breaker's V cabinet. Insert the hexagonal handle into the hexagonal shaft on the upper part of the mechanism, then rotate it clockwise by approximately 90 degrees to immediately close the isolating switch. This closing action can only be performed in the grounded division state. When the isolating switch is in the closed state, the grounding operation hole will be sealed by the opening/closing indicator sign. Users must not forcibly operate grounding against the sign's instructions; otherwise, it will violate the five-protection operation requirements.

Circuit Breaker Operation:

To open the switch, insert the hexagonal handle into the hexagonal shaft on the upper part of the mechanism and rotate counterclockwise approximately 90 degrees to immediately open the isolator switch. This operation is only valid when the isolator mechanism is closed and the circuit breaker is open. When the isolator mechanism is open, you can perform a closing operation on the isolator switch or a grounding closing operation.

Grounding Operation:

When the isolator is in the separated position, insert the hexagonal handle into the hexagonal shaft on the lower part of the mechanism and rotate it clockwise approximately 90 degrees to close the grounding circuit, and counterclockwise approximately 90 degrees to open the grounding circuit. When the grounding is in the closed position, the operating hole of the isolator will be sealed by the opening and closing indicator sign. Users must not forcibly operate the isolator against the sign's indication; otherwise, it will violate the five-protection operation requirements.
