Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and in particular to a power distribution cabinet. Background Art

[0002] A power cabinet is an electrical product used for switching, controlling or protecting in power generation, transmission, distribution, energy conversion and consumption. It mainly includes high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. In addition, there are also power cabinets that work outdoors.

[0003] The power cabinet is also called the distribution cabinet. The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The power cabinet is a cabinet made of steel to protect the normal operation of components. The materials used to make the power cabinet are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of power cabinets. Power cabinets are widely used and are mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0004] For example, Chinese patent CN202210701111.X discloses a moisture-proof power cabinet that is easy to maintain. It can be seen that the power cabinet can open the left and right sides of the power cabinet through detachable side cover plates to facilitate maintenance of the equipment installed inside the power cabinet. At the same time, the interior of the power cabinet can also be actively cooled by air through the two air cooling modes provided by the top processing box. At the same time, the device can also effectively isolate the external humid air from entering the cabinet and can also effectively dehumidify the cabinet, thereby effectively ensuring the normal humidity in the cabinet, avoiding the occurrence of accidents, and improving the stability of equipment operation. At the same time, the top processing box of the device can also be disassembled and replaced as a whole for maintenance.

[0005] Another example is a power cabinet with moisture-proof and dehumidification function disclosed in Chinese patent CN202310528227.2. It can be seen that when the moisture content in the power cabinet body is too high, the dehumidifier discharges the moisture in the power cabinet body to the outside, and the hot air fan blows out hot air to dry the moisture in the power cabinet body. The desiccant in the desiccant box absorbs the moisture in the power cabinet body, thereby achieving the effect of moisture-proof and dehumidification of the power cabinet.

[0006] Based on the search of the prior art, it can be known that when the power cabinet is in use, a large number of electrical equipment usually needs to be installed in the cabinet, and the electrical equipment will generate a large amount of heat when in use. This requires heat dissipation treatment inside the power cabinet during use. The existing heat dissipation method usually uses a fan to drive the surrounding air flow, thereby bringing the hot air in the cabinet out of the cabinet, thereby achieving the purpose of cooling. However, since the position of the fan is fixed relative to the power cabinet, this will make the heat dissipation range of the fan very limited, thereby reducing the heat dissipation range.
