高压环网柜被广泛使用于城市住宅区、高层建筑、工厂等电力供用中心的配电站以及箱式变电站中，是环网供电系统中带开关的电缆分支箱，其进出线端均由电缆联接。高压环网柜是为提高供电可靠性，使用户可以从两个方向获得电源，通常将供电网连接成环形。这种供电方式简称为环网供电。在工矿企业、住宅小区、港口和高层建筑等交流10KV配电系统中，因负载容不大，其高压回路通常采用负荷开关或真空接触器控制，并配有高压熔断器保护。该系统通常采用环形网供电，所使用高压开关柜一般习惯上称为环网柜。环网柜除了向本配电所供电外，其高压母线还要通过环形供电网的穿越电流(即经本配电所母线向相邻配电所供电的电流)，因此环网柜的高压母线截面要根据本配电所的负荷电流与环网穿越电流之和选择，以保证运行中高压母线不过负荷运行，然而现有高压环网柜散热性能较差，部件工作产生的热量并不能及时散发掉，导致其他部件受损，存在安全隐患。High-voltage ring network cabinets are widely used in distribution stations and box-type substations of power supply centers such as urban residential areas, high-rise buildings, and factories. They are cable branch boxes with switches in the ring network power supply system. connect. The high-voltage ring network cabinet is to improve the reliability of power supply, so that users can obtain power from two directions, and usually connect the power supply network into a ring. This power supply method is referred to as the ring network power supply. In industrial and mining enterprises, residential quarters, ports and high-rise buildings and other AC 10KV power distribution systems, due to the small load capacity, the high-voltage circuit is usually controlled by a load switch or a vacuum contactor, and is equipped with a high-voltage fuse for protection. The system is usually powered by a ring network, and the high-voltage switchgear used is generally called a ring network cabinet. In addition to supplying power to the power distribution station of the ring network cabinet, its high-voltage bus also passes through the current of the ring power supply network (that is, the current supplied to the adjacent power distribution station through the bus of the power distribution station), so the high-voltage bus of the ring network cabinet The cross-section should be selected according to the sum of the load current of the power distribution station and the ring network crossing current to ensure that the high-voltage busbar does not run under load. However, the heat dissipation performance of the existing high-voltage ring network cabinet is poor, and the heat generated by the components cannot be dissipated in time. If it falls off, other components will be damaged, posing a safety hazard.
