Description

电压无功综合优化补偿装置
技术领域
本实用新型是一种电力设备，用于10千伏和6千伏配电线路中，安装在高压输电架空线路上，为一种电压无功综合优化补偿装置。
背景技术
实施农村配电线路的无功补偿，不仅是无功补偿的重点组成，也是行之有效的降损节能技术措施。大多数农村配电线路，由于缺少无功补偿，而使线路损耗大，电压质量低劣，要改变这一状况，在配电线路上加装无功补偿装置是极为有效的技术措施。在配电线路上加装补偿电容器，可直接减少配电线路无功输入量，缩短无功输送距离，从而达到降损节能的目的，但从总体上看，这一有效的技术措施，却一直未能得到重视，究其原因，主要在于此类无功补偿设备没有形成规范，其技术上也存在问题，直接影响应用效果和人们对此种补偿方式的重视程度。一直以来，线路无功补偿都是在配电线路并联高压电容器实现，这种方法因不能随负荷的变化而自动投切，常常造成过补偿。由于农村线路在农闲和后夜时的负荷极少，这时如果主网也存在无功过剩和电压过高情况时，就会在线路上产生过电压而烧毁电力电容器，对此，及时加以控制投切是必需的选择；同时，大部分线路的负荷量都在变化，为平衡无功也需要自动控制投切。
发明内容
本实用新型要解决的问题是：现有农村配电线路缺少合适的无功补偿，需要性能优异的无功补偿装置来减少农网的电路损耗，提高电压质量。
本实用新型的技术方案为：电压无功综合优化补偿装置，包括跌落式熔断器、电压互感器型电源变压器、高压真空接触器、全膜高压并联电容器，高压线路功率监控终端及箱体，跌落式熔断器连接电压互感器电源变压器，电压互感器电源变压器提供装置电源，高压线路功率监控终端的输出连接高压真空接触器，高压真空接触器连接全膜高压并联电容器，电压互感器型电源变压器、高压真空接触器、全膜高压并联电容器，高压线路功率监控终端设置在箱体内。
箱体内设有GPRS通讯模块，GPRS通讯模块连接高压线路功率智能监控终端。
跌落式熔断器与电压互感器电源变压器之间设有电容型氧化锌避雷器。
本实用新型是为满足高压无功补偿的需要而开发设计的，采用了先进的电子技术、计算机控制技术，有效、合理的控制高压并联电容器组的投切，达到提高功率因数，降低线损，改善电压质量。
本实用新型适用于10千伏和6千伏配电线路中，安装在高压输电架空线路上，作为提高功率因数，减少线路损耗，节约电能，改善电能质量之用，也可用于小型化终端变电站10KV母线无功补偿。
本实用新型能实现高压并联电容器组的自动投切，同时本实用新型设置了GPRS通讯模块，具有遥测、遥控、遥信的功能，可通过GPRS远程主站控制，或通过短距离无线通讯模块在装置附近测控。另外，本实用新型为小型一体化箱变结构，安装方便，维护简单。
附图说明
图1为本实用新型的结构示意图。
图2为本实用新型的安装至意图。
具体实施方式
如图1所示，本实用新型包括跌落式熔断器1、电压互感器型电源变压器2、高压真空接触器3、全膜高压并联电容器4，高压线路功率智能监控终端5及箱体6，跌落式熔断器1连接电压互感器电源变压器2，电压互感器电源变压器2提供装置电源，高压线路功率智能监控终端5的输出连接高压真空接触器3，高压真空接触器3连接全膜高压并联电容器4，电压互感器型电源变压器2、高压真空接触器3、全膜高压并联电容器4，高压线路功率智能监控终端5设置在箱体6内，所述高压线路功率监控终端5为南京谷峰电子科技有限公司的PQC200系列高压线路功率智能监控终端。箱体6内设有GPRS通讯模块8，GPRS通讯模块8连接高压线路功率智能监控终端5。跌落式熔断器1与电压互感器电源变压器2之间设有电容型氧化锌避雷器7。
如图2，本实用新型安装在高压输电架空线路上。合上跌落式熔断器，电压互感器型电源变压器接通，二次回路AC220V电源接通，电压无功综合优化补偿装置开始工作，当高压线路功率智能监控终端检测到自变电站线路的电压，或功率因数，或运行时间处于预先设定的投切范围时，控制器接通分合闸的中间继电器，高压真空接触器吸合，将全膜高压并联电容器组成的电容器组投入线路运行。当线路的电压或功率因数或运行时间处于切除范围时，控制器释放分合闸的中间继电器，真空接触器跳闸，将电容器组退出运行。从而实现电容器组的自动投切，达到提高功率因数，降低线损，节约电能，改善电压质量的目的。
当线路电压高于过电压保护整定时，本实用新型延时30s将真空接触器跳闸，电容器退出运行，如果在30s时间内，线路电压恢复正常，接触器不跳闸。接触器跳闸后，当线路电压恢复正常时，本实用新型延时10分钟使接触器重新合闸，电容器投入运行。当线路电压低于过电压保护整定时，延时0.2～0.5s、失压时延时0.2～0.5s接触器跳闸。
当线路电压恢复正常时，本实用新型延时10分钟将接触器合闸。
当电容器组电流超过过电流保护整定时，本实用新型延时5s使接触器跳闸。当电容器相间击穿时，接触器延时0.2～0.5s跳闸，同时本实用新型自行闭锁。
当装置出现相间短路时，由跌落式熔断器快速切除故障相，同时接触器延时0.2～0.5s跳闸，并不再投入。
本实用新型的氧化锌避雷器作雷击过电压保护之用。
