Description
技术领域technical field
本发明涉及一种高压配电柜，具体是一种便于散热防潮的高压配电柜。The invention relates to a high-voltage power distribution cabinet, in particular to a high-voltage power distribution cabinet that is convenient for heat dissipation and moisture-proof.
背景技术Background technique
高压配电柜是指用于电力系统发电、输电、配电、电能转换和消耗中起通断、控制或保护等作用，电压等级在3.6kV-550kV的电器产品，主要包括高压断路器、高压隔离开关与接地开关、高压负荷开关、高压自动重合与分段器，高压操作机构、高压防爆配电装置和高压开关柜等几大类。高压开关制造业是输变电设备制造业的重要组成部分，在整个电力工业中占有非常重要的地位。High-voltage power distribution cabinets refer to electrical products that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, and the voltage level is 3.6kV-550kV, mainly including high-voltage circuit breakers, high-voltage Disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices, and high-voltage switchgears. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry, and occupies a very important position in the entire power industry.
高压配电柜在工作时，由于配电柜内安装了大量了接插件和各种电子元器件，导致配电柜的总电阻值很高，因为在导电的情况下会散发出大量的热量，使得配电柜的温度骤然提高，而配电柜往往都都是结构比较紧凑，空间比较小且为封闭式，特别是在用点高峰期，配电柜不能及时散热很容易导致配电柜内元器件的损坏，甚至发生火灾等事故，但如果采用抽风机搭配散热口散热，又会额外消耗能源，且外界空气进入，特别是阴雨天，空气中含有大量水分容易造成内部元件损坏。When the high-voltage power distribution cabinet is working, because a large number of connectors and various electronic components are installed in the power distribution cabinet, the total resistance value of the power distribution cabinet is very high, because a large amount of heat will be emitted in the case of conduction, The temperature of the power distribution cabinet suddenly increases, and the power distribution cabinet is often compact in structure, small in space and closed, especially during the peak period of use, if the power distribution cabinet cannot dissipate heat in time, it will easily lead to the inside of the power distribution cabinet. Damage to components, or even fire accidents, but if the exhaust fan is used to dissipate heat, it will consume additional energy, and the outside air will enter, especially in cloudy and rainy days. The air contains a lot of moisture and may cause damage to internal components.
