The present disclosure relates to an arc ventilation system of a distributing board, and more particularly, to an arc ventilation system of a distributing board to minimize an arc flowing forward to prevent damage. In the arc ventilation system of a distributing board in which a plurality of compartments are provided, a first compartment accommodating an electric power device which can be drawn in or out, among the plurality of compartments, comprises an arc blocking part blocking a space between the electric power device and the first compartment at an operation position of the electric power device.

Arc ventilation system of distributing board

The present invention relates to an arc ventilation system of a multi-stage distributing board, and more particularly, to an arc ventilation system of a multi-stage distributing board having an arc ventilation detour path, capable of preventing an arc generated in a lower compartment from damaging an upper compartment. The arc ventilation system of a multi-stage distributing board according to an embodiment of the present invention includes a first compartment provided at a first stage of an enclosure of the distributing board, a second compartment provided at a second stage located above the first stage, a side arc ventilation compartment provided at one side of the first compartment and the second compartment, and a middle arc induction compartment provided between the first compartment and the second compartment and communicating with the side arc ventilation compartment.

Arc ventilation system of multi stage distributing board

Provided is an earthing structure of an earthing truck that includes a frame with a terminal connection part and a moving part configured to support the frame and is configured to ground a bus or a cable while the moving part moves. The structure including: an earthing plate provided on a lower surface of the moving part; and an earthing member configured to provide a contact pressure to the earthing plate as it contacts the earthing plate when the moving part moves.

Earthing structure of earthing truck

A distribution panel includes a cabinet having a space formed therein and an inner partition positioned within the cabinet and partitioning a front power transformer (PT) chamber and a rear cable chamber, wherein the inner partition includes: a partition body, on which a bushing is disposed in a penetrating manner, having openings allowing an arc to pass therethrough; and an inner cover rotatably coupled to the partition body to open and close the opening, and rotated by an arc pressure when an arc accident occurs in the front PT chamber, to open the opening. Since an arc from the front PT chamber is spread to the rear cable chamber, pressure of the front PT chamber may be lowered, and a phenomenon in which a PT door is forcibly opened at a high speed is minimized, minimizing an accident.

Distribution panel

The present invention employs a separate rotation-adjusting member, which allows a position of a circuit breaker or a transformer to be recognized from outside without an error.
