Description

{Vibration proof for distribution board}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration damping device for a distribution board, and more particularly, to a vibration damping device for a distribution board, which prevents vibrations from being transmitted to a component located adjacent to the vibration damping portion.

Generally, a power device generally refers to a distribution device, a low-pressure device, a high-voltage device, a transformer device, and the like. The device generally includes a power device such as a circuit breaker or a magnetic device to open or close external power.

Among the various power devices described above, the switchgear, which is the most widely used power device in the industrial field, has a power capacity required for various switches, instruments, and relays (relays) for operation and control of power plants and substations, , Which mainly distributes power supplied from the outside in the indoor wiring such as a building and re-supplies it to each element in the house, and at the same time, performs the function of opening and closing the power supply.

Such a distribution board is composed of a structure for attaching and supporting unit devices such as a breaker or a protective relay, and a collection of conductors (bus bars, cables, etc.) connecting and connecting the unit devices. Depending on the receiving voltage, , High-voltage and low-voltage switchboards. The main circuit for transmitting electric power in the above-mentioned distribution panel is composed of a booth which is a conductor.

Such a switchboard is composed of a horizontal panel, a vertical panel and a back panel, and is equipped with a function of protecting various electronic devices from the external environment, including various electronic devices installed inside the switchboard.

In addition, the distribution board is usually installed in units of buildings, units, ships, and small-sized caterpillars. When a ship is placed in an unstable state by vibration or movement from time to time, such as a ship, And the vibration or shock transmitted to the distribution board causes mechanical tripping or malfunction of the circuit breaker to cause a problem in the supply of electricity to the ship.

In order to reduce vibrations due to such a problem, the packing is inserted. However, in order to combine the packing, the packing of the rubber material must be inserted in a forced fitting manner, so that the packing tears frequently during the fitting process.

In addition, it has been pointed out that a worker takes a lot of time in the work process because the worker is injured in the process of forcibly putting the packing in, or the combination work is performed using a separate tool.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide an anti-vibration device for preventing vibrations from being transmitted to a component located adjacent to an excavator, And an object thereof is to provide a vibration damping device for a distribution board capable of easily coupling the vibration damping device inside the distribution box.

According to another aspect of the present invention, there is provided a vibration damping device for a distribution board, the device comprising: a third housing disposed in a direction of one side of a through hole formed in a corner of the first housing; And a coupling part which is inserted into the through hole and rotates while being engaged with the coupling part.

The through hole may be formed with guide grooves whose inner diameters increase in both directions, and the coupling portions may be formed to protrude in both directions corresponding to the shapes of the through holes and the guide grooves.

A fastening groove may be formed between the fastening portion and the third housing to insert a part of the quick plate by the rotation of the third housing.

The third housing may be formed to have a predetermined height so as to prevent the first housing from contacting the housing of the distribution board.

The third housing may include one or a plurality of members selected from the group consisting of a urethane resin, an acrylic resin, a silicone resin, and an emulsion resin so as to prevent the vibration of the quick plate from being transmitted to the outside.
