Type identification

电压互感器的型号由3～4个拼音字母及数字组成。通常它表示电压互感器的线圈型式、绝缘种类、铁芯结构及使用场所等。字母后面的数字表示电压等级（单位KV）。字母含义如下：

Voltage transformer models consist of 3 to 4 alphabetic letters and numbers. Usually it represents the coil type, insulation type, core structure and use place of voltage transformer. The number after the letter indicates the voltage level (KV). The letters have the following meanings:

J：在第一位，表示电压互感器；在第三位时，表示油浸式；在第四位，表示接地保护；

J: In the first place, it means voltage transformer; in the third place, it means oil-immersed type; in the fourth place, it means grounding protection;

S：在第二位，表示三相；

S: In the second place, it means three-phase.

D：在第二位，表示单相；

D: In the second place, it means single phase.

G：在第三位，表示干式；

G: In the third place, it means dry.

Z：在第三位，表示浇注式；

Z: In the third place, it means pouring type.

W：在第四位，表示五铁芯柱式；

W: In the fourth place, it represents the five-core column type.

B：在第四位，表示有补偿线圈；

B: In the fourth place, there is a compensation coil.

C：在第二位时，表示串级绝缘；在第三位时，表示瓷绝缘。

C: In the second place, it means cascade insulation; in the third place, it means porcelain insulation.

例如：JDJJ-35型号的电压互感器代表单相油浸式可供接地保护用的电压互感器，电压等级为35KV。

For example, the JDJJ-35 voltage transformer represents a single-phase oil-immersed voltage transformer for grounding protection, with a voltage level of 35 KV.
