Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a leakage protection function. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is made of steel and is used to protect the normal operation of components. Its main function is to open and close, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion process of the power system.

[0003] Some equipment on the market generally uses a conductive plate and a grounding wire to conduct electricity when leakage occurs in the box during operation to avoid electric shock. The heat dissipation efficiency of the box can be improved through the heat sink, and the air in the box can be circulated through the fan, so that the heat generated by the box during operation can flow out from the steering head.

[0004] However, in actual use, after long-term use, the above-mentioned equipment will have aging problems inside the equipment, which will create the risk of leakage, and then cause current to be generated in the box, which can easily damage the electrical components inside the box and make the equipment unusable. In view of this, we have proposed a distribution cabinet with leakage protection function. Utility Model Content

[0005] The purpose of the present invention is to provide a power distribution cabinet with a leakage protection function to solve the problems raised in the above background technology.

[0008] A spring is fixedly connected to one side of the inner wall of the box, a mounting seat is sleeved inside the spring, one end of the spring is fixedly connected to a limiting plate, and the limiting plate is arranged in a circular ring shape.

[0009] Preferably, a mounting seat is sleeved inside the limiting plate, and the size of the limiting plate is adapted to the size of the mounting seat, which allows the limiting plate to move well on the outer surface of the mounting seat.

[0010] Preferably, the size of the interior of the leakage protector is adapted to the size of the mounting seat, and the side of the leakage protector close to the card block is in contact with the limit plate, which allows the limit plate to limit the card block well inside the card slot through the elastic force of the spring.

[0011] Preferably, the size of the card block is adapted to the size of the card slot, and the mounting seat is connected to the conductive rod, which enables the conductive rod to transmit current to the leakage protector through the mounting seat.

[0012] Preferably, a placement groove is opened on one side of the inner wall of the box, a fixing piece is clamped inside the placement groove, and a placement plate is fixedly connected to one side of the fixing piece.

[0014] Compared with the prior art, the present invention provides a power distribution cabinet with leakage protection function, which has the following beneficial effects:

[0015] 1. The distribution cabinet with leakage protection function can prevent the equipment from aging and causing leakage after long-term use, which may damage the electrical components inside the equipment. When the equipment leaks, the electricity will be transmitted to the conductive rod. The conductive rod will transmit electricity to the ground and at the same time, the mounting seat arranged on the inner wall of the box will receive the current. In this way, the leakage protector arranged on one side of the mounting seat will also receive the current, so that the power inside the equipment can be quickly cut off, which can effectively prevent the equipment from being damaged by leakage. When the leakage protector is damaged, the leakage protector is rotated to move the card block from the vertical part of the L-shaped slot to the horizontal part, so that the leakage protector can be quickly replaced and repaired, so that the leakage protector can effectively prevent the equipment from being damaged by leakage.

[0016] 2. In order to enable the leakage protector to detect leakage more quickly, the distribution cabinet with leakage protection function has fixings fixed on both sides of the placement plate stuck in the placement slots opened on the inner wall of the box. The placement slots are connected to the installation slots, and the fixings are L-shaped, which can make the horizontal part of the fixings contact with the outer surface of the conductive rod, so that the electrical components arranged on the upper surface of the placement plate can make the current flow to the conductive rod faster when leakage occurs, which enables the leakage protector to detect leakage more quickly.
