产品说明
1. JK3PSZT系列静态开关是晶体模组产品,是为静态电容器组基础建造的模组,达到功率因数校正用途。这些电容器组使用晶闸管代替传统的接触器连接每个大组电容器并且他们是理想的设施哪里漏电流受损快速和大的波动(负载变化的间隔可以从瞬间到8秒或10秒)。
2. JK3PSZT系列的静态开关单位被设计成连接和断开电容器以毫秒为单位。
它们可以用来构建在电容器的各种步骤,或为个别的负载补偿,必须获得即时补偿由于连接或断开的缺陷,例如: 在焊接设备,起重机,升降机等
3. 自动电容组静态系统盘-JK3PSZT系列电容器组静态系统,为电网脉动负载校正功率因数目的而设计。电源里的变化相对比较快(毫秒),为了开关操作完美投入或段开,以至于透过晶闸管控制,再连接到一个电压控制电路板,以便连接和断开电容器实行零电压差动作。
预防连接和断开步骤之间的瞬变电流,获得负载波动即时的回应。
4. 电容器组静态系统的功能和优势,这种补偿系统的功能或优势,如下:
(1)立即回应补偿的要求。
(2)功率因数校正回应时间,可以是一个单一网络频率周期,以此方式实现几乎瞬间的补偿。
(3)消除启动电容器的衔接所产生的瞬变电流.
(4)发生在电压网络衔接匹配电容器时,当部分或完全加载时,如看到Fig.1。
二、功能说明
1. 具有RST各相保险丝断路指示灯,并提供异常输出接点,可做系统紧急控制之用。
2. JK3PSZT系列的静态开关单位,连接和断开电容器以毫秒为单位。
