南阳干式变压器：互感器

互感器 　　
概述
在测量时用于变换电压的南阳干式变压器称为电压互感器，用于变换电流的南阳干式变压器称为电流互感器。
在系统中，高电压和大电流不能直接侧量，必须借助互感器将一次电量转变为具有标准值的二次电量，再接入测量回路。
电压互感器是并接在线路里，电流互感器是串接在线路里。互感器还要作为各种继电保护的信号电源。互感器的绝缘等级与南阳干式变压器相同。现行国家标准为GB12电 话：0635-888829907一1997《电压互感器》和GB1208-1997《电流互感器》。
目前，除常规的互感器外，市场上还有许多新品种，如带有保证暂态特性二次烧组的电流互感器、倒立式互感器、SF6气体绝缘互感器、电容式电压互感器、双二次绕组的电压互感器、双变比或多变比电流互感器、容性电压互感器、低励磁防谐振电压互感器、多二次绕组电流互感器等。

Transformer

Outline
Measurement used to transform the voltage transformer is called a voltage transformer used to transform the current transformer is called a current transformer.
In the power system, high voltage and high current can not be the direct side, with the transformer once power into the electricity the second with a standard value, and then access the measuring circuit.
Voltage transformer and connected to the line, the current transformer is connected in series in the line. Transformer but also as a signal power of all kinds of protection. Transformer insulation class transformer. The current national standard GB1207 voltage transformer in a 1997 with GB1208-1997 "current transformer".
In addition to the conventional transformer, the market there are many new varieties, such as with the current transformer of the group to ensure that the transient characteristics of the second burn, inverted transformer, SF6 gas-insulated transformers, capacitor voltage transformers dual voltage transformer secondary winding, dual variable ratio or volatile than the current transformers, capacitive voltage transformers, low excitation anti-resonant voltage transformer current transformer of the multi-primary and secondary windings.
