产品特点Product Features
1、用于低压电网，靠近用户负载，采用智能投切仪的无功功率补偿技术，不需附加缓冲电感，可直接将电容器投人电网，实现了高可靠性、高效性。
2、采用计算机数字化控制技术，对三相对称或非对称供电线路中的无功功率进行实时、动态跟踪补偿，使功率因数始终保持在0,9以上(或按用户要求）。在电网电压高低不同时采用不同的补偿算法以确保不发生欠补偿和过补偿（过补偿会引起电网电压升高）；
3、抗干扰能力特强，能抵御从电源直接输入的2000V干扰脉冲。
4、输出电路采用先接通先分断，先分断先接通的循环工作方式或按要求的其他编码方式。
5、有过电压判断，快速逐级切除补偿电容的功能，切除全部电容的时间小于1分钟。
6、有超低负荷判断、显示、封锁功能，防止投切振荡。
7、对电网过补偿，欠补偿情况都能显示并自动作出相应处理。
8、电流取样信号可直接从回路中串联取出，其输入阻抗小于0.05Ω，无需另加电流互感器。
1.For low-voltage power grid,close to the user load,thyse of intelligent switching deMce readive wer compensatiorl technology without addtionaI buffer inductour,capacitors can be directly into the grid,to achiee a high reliability,high efficiency;
2.The use of computer digital control technology,three-phase symmeMcal or asymmetrical pawer supply lines in real-time,dynamic Irackind compensation,the power factor is always maintained at 0.9 or more(or according to user requirements)+When the grid voltage is different,different compensation a gorllhms are adopted to ensure that no under-compensation and over-compensation will occur(over-compensation will cause the grid voltage to rise)
3.strong anti-interference abiliw,able to resist the direct input from the power 2000V interference pulse.
4.The output circuit first connected to the first break,the first cut off the cycle of work or other encoding required.
5.There is over-voltage judgment,fast step-by-step removal of compensation capacitor function all the capacitor removal time is less than 1 minute
6.Itra-low load judgments,display,blockade function to prevent switching oscillauon.
7.The grid over compensation,compensation can display and automatically compensate for the corresponding treatment.
8.the current sampling signal can be directly removed from the loop in series,the input impedance is less than 0.050 without add tiona current transfomer.
