【技术实现步骤摘要】
本技术涉及一种高压线路无功补偿电容器的自动投切装置,特别是一种高压无功补偿智能装置。该装置采用高压一体化结构,它可广泛用在6-10KV线路上和变电所内,它配合高压补偿电容器,对用电线路和设备的无功功率进行自动补偿。打破了高压线路无功补偿不能按最佳值配置的问题。长期以来高压线路的无功补偿,主要是采用固定补偿的办法,而固定补偿又有很多不能解决的问题。它们存在的不足如下 1、电压过高时不会及时退出运行,会烧坏电容器或引起爆炸。2、不能按线路的最佳值补偿,因线路负荷及功率因数的大小是随时间而变化的。如果按最大负荷时的无功量进行补偿,在负荷减小时会产生过补偿现象。一般的补偿值都设计在较低负荷运行值。3、由于补偿值不足,在高负荷时电压降大,影响线路的供电质量。4、由于达不到最佳补偿值,节电效果不明显。5、如果因电源故障或其它因素造成缺相时,电容器两相运行,会产生中星点位移,影响电压质量。本技术的目的是针对以上的不足而研制的一种高压无功补偿智能装置,它是由三部分组成,一是该装置的静动触头采用刀开关形式,配合机械传动机构和缩能弹簧的作用,受电磁铁的吸合而达到开关的分合功能; ...
