概述  Outline

本智能型一体化变电站是华电电气公司推出的国产化美式箱变。该产品作为电缆化配电网中重要的供电单元，集高压控制、保护、变电、以及配 电设备于一体的成套预装产品，广泛应用于城乡配电网之中。该产品将高压负荷开关、高压熔断器置于变压器油中，具有与变压器身共箱或分箱两种 结构形式。油箱采用全密封结构，配有油温表、油位表、压力表、压力释放阀、放油阀等元件监测变压器运行状况。该产品分为环网型、终端型及电 源型供电方式。为了使此种产品更适合于我国电网的实际要求，华电公司又推出了插拔型干式熔断器，熔丝的熔断不影响变压器油的性能。根据低压 馈出要求的复杂程度，此产品分为标准型、加强型和综合型三种外壳形式，使用户和设计单位在选型时，做到更灵活、更经济。

This intelligent integrated transformer substation is a nationalized type American box substation developed by HUADIAN ELECTRIC Company. As an important power supply unit in the cable distribution network, it is an in tegrated prefabricated product of high voltage control, protection, power transformation and power distribution, whichis widely used in the urban and rural distribution network.The high voltage load switch and high voltage fuse are put into the transformer oil, so this product has two structure forms of one box and divided box with the transformer body. The oil box is of full-sealed structure with oil temperature indicator, oil level gauge, pressure gauge, pressure relief valve and oil drain valve to monitor the operation condition of the transformer. This kind of products has three types of power supply modes ring network type, terminal type and power type. In order to make the product meet the actual demands of the power grid in China better, HUADIAN Company promotes plug-pull dry type fuse and the fusing of the fuse wire has no effect to the performance of transformer oil. According to the complicated degree of low voltage outgoing demands, this product has three types of enclosure - standard type, reinforced type and integrated type, as a result, the clients and design agents have more choices.
