KJCD-01/MX Intelligent Electric Operation Solution, featuring an MCU chip integrated circuit for intelligent judgment of the closing/opening status of the load switch, operates the mechanism electrically according to customer instructions, enabling local closing/opening and remote closing/opening functions. It provides protection against motor overload, undercurrent, or jamming, ensuring the safety of critical components. The controller has a function to signal equipment faults, greatly facilitating routine maintenance.

KJCD-01/NX Standard Electric Operation Plan, featuring PCB terminal integration, electric operation of the mechanism is achieved through relay contacts within the controller. It lacks motor protection and fault alert functions, classifying it as an economic electric operation solution.

This series of products is factory-shipped after full inspection and conforms to the requirements of GB 3804-2004 "AC High-Voltage Load Break Switches - 3.6KV 40.5KV," GB 3906-2006 "AC Metal-Enclosed Switchgear and Control Equipment - 3.6KV-40.5KV," and "High-Voltage AC Load Break Switch-Fuse Combination Appliances."

User Operation Instructions

Closing operation:

The mechanism is installed and secured on the cabinet. Insert the mechanism handle into the operation shaft located on the upper part of the mechanism, rotate the handle clockwise about 90 degrees. As the spring is compressed to the energy release critical point, it releases energy. Under the energy release force, the load switch is pushed to close the main circuit. When electrically closing, power is supplied to the mechanism and a closing signal is given. The controller automatically detects the position of the load switch and the status of all interlock circuits. If all circuits meet the closing conditions, the controller automatically starts the mechanism motor to close the main circuit of the load switch. At this time, the grounding function of the mechanism is locked, and grounding operations are not allowed.

Circuit breaker operation:

During manual disconnection, insert the mechanism handle into the operating shaft located at the top of the mechanism, rotate the handle counterclockwise approximately 90°, and release the latch when the mechanism's coiled spring compresses to the critical energy release point, thereby pushing the load switch to complete the main circuit disconnection. For electrical disconnection, the user provides a disconnection signal; the controller automatically identifies the load switch's open or closed position and the status of each interlock circuit. If all circuits meet the conditions for disconnection, the controller automatically starts the mechanism motor to complete the main circuit disconnection of the load switch. In the disconnection state, you can perform a closing operation or grounding operation.

Grounding and circuit breaking/switching operations:

Grounding Closing: Insert the mechanism handle into the grounding operation shaft at the bottom of the mechanism, rotate clockwise approximately 90°. The grounding energy storage spring releases energy instantaneously as it compresses past the midpoint, pushing the grounding switch to complete the grounding closing. At this point, the mechanism interlock is locked, preventing main circuit closing.
Grounding Break: Insert the mechanism handle into the grounding operation shaft at the bottom of the mechanism, rotate counterclockwise approximately 90°. As the grounding energy storage spring compresses past the midpoint, it releases energy instantly to push the grounding switch into the break position. At this point, the mechanism interlock is in the open state, allowing for closing and opening operations on the load switch.
