Description

一种低压无功补偿柜
技术领域
本实用新型属于电力供电系统控制技术领域，特别涉及一种低压无功补偿柜。 
背景技术
低压无功补偿装置可以提高电力供电系统的功率因数，降低线损，稳定供电电压，提高电力供电系统的效率和可靠性。 
现有的低压无功补偿装置存在电容器投切涌流大、电容器高温易爆炸、功率消耗大、耐电压电流冲击低及接触器功率因数控制器易损坏等问题，导致低压无功补偿装置维修频繁，严重影响了正常生产。如CN201120522251.8公开的一种低压无功补偿柜，主要包括柜体（1），柜体（1）内部设有电容器（2）、电抗器（3）、刀熔开关（4）、熔断器（5）、投切开关（6）、控制器（7），柜体（1）的面板上设有功率因数表（8）、电流表（9）、转换开关（10），方便用户进行实时观测，其特征在于：投切开关（6）采用晶体闸流管，柜体（1）顶部设有散热用的风机（11），面板上设有风机控制开关（12）。其不足之处在于：不仅不能将监测数据和运行状态实时远传给后台管理系统，而且不能进行无功补偿。 
实用新型内容
本实用新型的目的在于提供一种低压无功补偿柜，不仅解决现有的低压无功补偿装置易损坏、维修频繁，严重影响正常生产的技术问题，而且可将监测数据和运行状态实时远传给后台管理系统。 
为实现本实用新型的目，本实用新型采用的技术方案是：一种低压无功补偿柜，包括壳体，所述壳体内设有低压电容器、智能型无功功率自动补偿控制器、电流互感器、小型断路器及智能式低压复合开关，所述低压电容器、智能型无功功率自动补偿控制器、电流互感器、小型断路器及智能式低压复合开关之间通过线缆连接，所述电流互感器连接有控制器，所述控制器端连接有无线通讯模块。 
所述低压电容器包括三相共补自愈式低电压并联电容器和单相分补自愈式低电压并联电容器。 
所述智能式低压复合开关包括微处理器和磁保持式继电器。 
 所述壳体的两侧壁上均开有通风窗。 
本实用新型是这样实现的，所述智能式低压复合开关包括微处理器和磁保持式继电器,所述磁保持式继电器有48个，分别与48路所述的低压电容器的一端相连，当需要投入/切除电容器时，所述智能型无功功率自动补偿控制器和微处理器通过设定程序自动判断过零点发出投/切命令，驱动所述磁保持式继电器在电压过零时闭合或在电流过零时断开，从而使与所述磁保持式继电器连接的所述低压电容器并入或退出相与地之间的回路，根据“两相间跨接电容可以在两相间转移有功电流”的原理，即可使各相有功电流达到平衡；所述电流互感器连接有控制器，所述控制器端连接有无线通讯模块，可将监测数据和运行状态实时远传给后台管理系统，方便远程控制台了解各个无功补偿柜的情况；所述低压电容器包括三相共补电容器和单相分补电容器，可实现分补共补，用以改善功率因数，提高供电质量，减少电能损耗。
