高压配电柜容易出现故障的元器件
高压配电柜容易出现故障的元器件
High voltage switchgear prone to failure components
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、高压防爆配电装置等几大类。
High-voltage distribution cabinet refers to the power system for power generation, transmission, distribution, power conversion and consumption in the role of on-off, control or protection, the voltage level of 3.6 kV ~ 550 kV electrical products, mainly including high-voltage circuit breakers, high-voltage disconnector and grounding switches, high-voltage load switches, high-voltage automatic reclosure and segmentation, high-voltage. Operating mechanism, high voltage explosion-proof distribution device and so on.
通常高压配电柜出现故障，往往是其中一个或者几个元器件出现了故障，从而影响了整体的运行。下面山西配电柜厂家锦泰恒总结出以下几个元器件是比较容易出故障的：
Usually high-voltage distribution cabinet failures, often one or several components of the fault, thus affecting the overall operation. The following Shanxi power distribution cabinet manufacturer Jintai Heng concludes that the following components are prone to failure.
1、电缆
1. Cable
电缆故障一般都是相间短路，即使是单相短路，由于放电时间长，也会慢慢演变为两相或三相短路。这时候需要排查故障点，处理好故障时候才能通电，否则会烧坏更多的设备。
Cable faults are generally inter-phase short circuit, even if the single-phase short circuit, due to long discharge time, will gradually evolve into two-phase or three-phase short circuit. At this time we need to check the fault point, handle the fault before power on, otherwise it will burn more equipment.
2、电压互感器
2. Voltage transformer
电压互感器故障通常导致的结果是一次侧熔丝熔断，电压互感器内部发生匝间、层间、相间及一相接地都有可能导致一次侧熔丝熔断。电压互感器二次侧故障时，如果二次侧熔丝选配过大，也容易导致一次侧熔断器烧坏。10kv电源一相接地，另外两相的对地电压会增加为根号三倍，从而导致电流变大，也会烧坏熔丝。
Voltage transformer faults usually result in primary fuse fuse. Interturn, interlayer, phase and phase grounding within the voltage transformer may lead to primary fuse fuse. When the secondary side of the voltage transformer fails, if the secondary side fuse is too large, it is easy to cause the primary side fuse to burn out. The 10 kV power supply is grounded in one phase, and the voltage to the ground of the other two phases will triple the root number, resulting in a larger current and burning out the fuse.
3、电流互感器
3. Current transformer
电流互感器的故障通常是铁芯过热，严重时容易炸裂互感器。电流互感器运行中如果出现过负荷、二次开路或绝缘损坏引发放电，都会造成声音异响，这时候需要分析原因，采取相应措施解决故障。
The fault of current transformer is usually overheated by iron core, so it is easy to burst transformer when serious. If there is overload, secondary open circuit or insulation damage in the operation of current transformer, it will cause abnormal sound. At this time, it is necessary to analyze the reasons and take corresponding measures to solve the fault.
4、避雷器
4. Lightning arrester
避雷器作为保护开关设备的主要元器件要定期检修，通常避雷器故障有磁绝缘损坏或者直接爆炸，避雷器一旦出现故障要及时更换。
As the main component of protective switchgear, the lightning arrester should be regularly overhauled. Usually the failure of the arrester has magnetic insulation damage or direct explosion. Once the arrester fails, it should be replaced in time.
