工 作 原 理

补偿变压器每相具备两组完全相似220V初级绕组，从次级绕组上获得补偿电压串接于主电路中，其单相接线图如图。
补偿装置输出电压与输入电压之间存在如下关系。
U2=U1±ΔU
式中：U2—输出相电压
U1—输入相电压

ΔU为补偿电压。它大小和相位与补偿变压器初级绕组连接方式关于。如把两个初级绕组串联连接后正向接入网络相电压，则可得到一种与网络相电压同相补偿电压；若反向接入，则得到一种反相补偿电压。此外，如将两个补级绕组并联后正向或反向接入网络相电压，则可得到为串联时2倍正相或反相补偿电压。如果两个初级绕组不接入网络，并使之短接，则补偿电压为零，即U2= U1。本装置是依照上述规定拟定了接触器五种通、断状态。
1、 直通档：K1—K3接通，Kd1—2、Kh1—2断开，此时K1—K3主触头闭合，使初级绕
组短接；Kd1—2、Kh1—2主触头断开，使初级绕组不接入网络，因而补偿电压为零。
2、 降I档：K1接通，K1主触点闭，K2、K3断开，K2、K3主触头断开，初级绕组
串联连接；Kh1—2接通，Kh1—2主触头闭合，Kd1—2断开，Kd1—2主触头断开，使初级绕组正向接入网络相电压，在次级绕组上得到一级正相补偿电压，输出电压比输入电压低一级补偿电压。
3、 降II档：与降I档区别在于K1断开，K2、K3接通，初级绕组变化成并联连接。次
级绕组上得到二级正相补偿电压，输出电压比输入电压低二级补偿电压。
4、 升I档：与降I档区别在于Kh1—2断开，Kd1—2接通，使初级绕组反相接入网络相
电压，在次级绕组上得到一级反相补偿电压，输出电压比输入电压高一级补偿电压。
5、 升II挡：与升I档区别在于初级绕组由串联变化成并联连接，即K1断开，K2、K3
接通。因而在次级绕组上得到二级反相补偿电压，输出电压比输入电压高二级补偿电压。

交流接触器切换是按输出电压指令来进行，只要输出电压超过设定最高最低容许值，通过接触器切换使之恢复到容许值之内。换挡切换过程在2个周波（40ms）内完毕。
principles
Each phase of the compensation transformer has two similar sets of 220V primary windings. The compensation voltage acquired from secondary winding is connection in a serial to the main circuit. The single -phase connection drawing is shown in the figure.
Output voltage and input voltage of the compensation device have the following relations.
U2=U1±ΔU
In the formula：U2—output phase voltage
U1—input phase voltage

ΔU is the compensation voltage，and the amplitude and phase position has relations with the connection method of the compensation transformer primary windings. If in series two primary windings are connected to the power source with same polarity (positive polarity)，a same phase position compensation voltage is obtained. Otherwise，in series two primary windings are connected to the power source with negative polarity，a reverse phase position compensation voltage is obtained. Besides，if two primary windings are paralleled，the compensation voltage amplitude will be increased one times. If two primary windings short circuit and disconnected from the power source，then the compensation voltage shall be zero，To switch eight contactors realize above five voltage regulation functions.
6、 Feed-through position：K1—K3 close，Kd1—2 and Kh1—2 open. Contact K1—K3 closed make the primary winding short circuit；contact Kd1—2 and Kh1—2 open are cut off to make the primary winding to disconnected from power source so that the compensation voltage is zero.
7、 Decrease I position：K1 close，and then K2 and K3 open. The primary windings are connected in a series；Kh1—2 close and Kd1—2 open make the primary winding connected to the power source in positive polarity，one positive phase compensation voltage is obtained at secondary winding. The output voltage is 1 level less than the input voltage.
8、 Decrease II position：the differences from Decrease I position are：K1 open，K2 and K3 close and the primary windings are paralleled. The output voltage is less than the input voltage 2 levels.
9、 Increase I position：the difference from Decrease I position are：Kh1—2 open，Kd1—2 close make the primary winding connected to the power source in reverse polarity，one reverse phase compensation voltage is obtained at the secondary winding. The output voltage is 1 level more than the input voltage.
10、 Increase II position：the difference from increase I position are：series connection is changed into parallel connection，namely K1open，K2 and K3 are close so that II level reversed phase compensation voltage is obtained at the secondary winding. The output voltage is more than the input voltage 2 levels.

Upon the measured voltage of output，AC contactors will be switched according to the controller commend. Once the output voltage over the maximum setting or below the minimum setting ,it can be recovered to nominal voltage within 2 cyclic waves (40ms).
