Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinets, and specifically relates to a discharge protection structure of a power distribution cabinet. Background Art
[0002] A distribution cabinet is a device used for power distribution. It is usually installed at a specific location in a building, factory or power system to distribute electrical energy. It mainly meets the needs of the power system and ensures the stable, safe and efficient distribution of electrical energy. With the rapid development of industry and daily life, the demand for electricity is increasing. The power system needs a device to reasonably distribute electrical energy to ensure a stable supply of electrical energy. The design and manufacture of distribution cabinets should meet various environmental and safety standards to ensure their safe and reliable operation.
[0003] The aging of distribution cabinet equipment will cause the insulation performance to deteriorate or be damaged, resulting in discharge. When static electricity accumulates to a certain level, it will also cause the equipment in the distribution cabinet to discharge. The distribution cabinet discharge will cause a short circuit failure, which will burn the equipment in the distribution cabinet and may even cause a fire, which will have a serious impact on normal operation. The sparks and arcs generated by the discharge cause safety risks such as electric shock and fire, posing a threat to workers and the surrounding environment. In order to reduce the disadvantages and shortcomings brought about by the discharge of the distribution cabinet, we propose a distribution cabinet discharge protection structure, and appropriate measures need to be taken to reduce these risks. Utility Model Content
[0004] The purpose of the utility model is to provide a discharge protection structure for a power distribution cabinet to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a discharge protection structure of a distribution cabinet, comprising a distribution cabinet, an inner cavity of the distribution cabinet is fixedly connected to a copper busbar, a lower surface of the distribution cabinet is fixedly connected to a first cylinder, a lower surface of the first cylinder is fixedly connected to a bellows, a lower surface of the bellows is fixedly connected to a second cylinder, an upper surface of the second cylinder is fixedly connected to the ground, an inner cavity of the second cylinder is provided with an angle steel, the angle steel is an embedded part, a side wall of the angle steel is fixedly connected to a grounding busbar, and the other end of the grounding busbar is connected to the copper busbar.
[0006] Preferably, the inner cavity of the first cylinder is symmetrically fixedly connected with a first inner plate, and the side wall of the first inner plate is gap-matched with the side wall of the grounding busbar; the inner cavity of the second cylinder is symmetrically fixedly connected with a second inner plate, and the side wall of the second inner plate is gap-matched with the side wall of the grounding busbar.
[0007] Preferably, the side walls of the power distribution cabinet are painted with coating paint.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: by using copper bars and grounding busbars in the distribution cabinet and performing good grounding treatment, good grounding treatment can effectively conduct the generated static electricity and avoid harm to the human body caused by static electricity accumulation. At the same time, it can also prevent fires caused by arcs or sparks generated by electrical faults and avoid equipment failures due to static electricity accumulation. By sleeved on the angle steel inside the cylinder on the grounding busbar and buried in the soil as a connection point, the reliability of grounding can be enhanced, so that the contact between the grounding busbar and the soil is good, avoiding the grounding effect being affected by poor contact. When setting the grounding busbar in the distribution cabinet, the position of the grounding busbar can be conveniently set using a cylinder and a corrugated pipe, making the grounding treatment more flexible and convenient, effectively protecting the safety of staff, avoiding the impact of static electricity accumulation on equipment, enhancing the reliability of grounding, and reducing electromagnetic interference. These advantages and benefits are crucial to the safe operation and maintenance of the distribution cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figure 1-4The utility model provides a discharge protection structure of a distribution cabinet, including a distribution cabinet 1, an inner cavity of the distribution cabinet 1 is fixedly connected to a copper busbar 2, a lower surface of the distribution cabinet 1 is fixedly connected to a first cylinder 3, a lower surface of the first cylinder 3 is fixedly connected to a bellows 4, a lower surface of the bellows 4 is fixedly connected to a second cylinder 5, an upper surface of the second cylinder 5 is fixedly connected to the ground, an inner cavity of the second cylinder 5 is provided with an angle steel 6, the angle steel 6 is an embedded part, a side wall of the angle steel 6 is fixedly connected to a grounding busbar 7, and the other end of the grounding busbar 7 is connected to the copper busbar 2.
[0016] Before using the distribution cabinet 1, first connect the grounding busbar 7 to the copper busbar 2 to ensure that the connection between the grounding busbar 7 and the copper busbar 2 is reliable and there is no looseness or falling off at the connection. Then, penetrate the bottom of the distribution cabinet 1 and connect with the first cylinder 3. The grounding busbar 7 is protected by the first cylinder 3. At the same time, a bellows 4 is provided. The position of the grounding busbar 7 can be easily modified through the bellows 4. Then, a second cylinder 5 is provided at the bottom at the same time. The second cylinder 5 can protect the pre-buried angle steel 6. A section of the angle steel 6 buried in the soil is used as a connection point to further enhance the reliability of grounding and ensure good contact between the grounding busbar 7 and the soil. This can effectively connect the potential of the distribution cabinet 1 to the earth. After connecting the grounding busbar 7 to the angle steel 6, the second cylinder 5 is fixed to the ground.
