一种建立在低压罐体侧表面的GIS母线电压测量装置
摘要：
本发明公开了一种建立在低压罐体侧表面的GIS母线电压测量装置，该电压测量装置包括金属传感方片、气体绝缘组合电器、电阻、电缆、测压器以及电压显示器；其中，气体绝缘组合电器包括具有圆柱结构的高压导体和外罐体；金属传感方片是从外罐体的侧表面切割下来的一部分，并且在测量电压之前，将其黏贴在外罐体侧表面的切口处；电阻的一端连接金属传感方片，另一端连接外罐体；电缆一端接电阻，另一端接测压器；电压显示器连接测压器，用于计算并显示高压导体对外罐体的电压值。因此，采用本发明提供的电压测量装置，能够通过测量电阻电压，获取气体绝缘组合电器内高压导体对外罐体的电压值，实现实时监测高压输电线路的运行状态的目的。
摘要（英）：

The invention discloses a GIS bus voltage measurement device established on a side surface of a low voltage tank. The voltage measurement device comprises a square metal sensing sheet, a combined electric gas insulation device, a resistor, a cable, a voltage tester and a voltage display, wherein the combined electric gas insulation device comprises a high voltage conductor in a cylindrical structure and an outer tank, the square metal sensing sheet is a part cut from a side surface of the outer tank, before a voltage is measured, the square metal sensing sheet is pasted at a cutting portion at the side surface of the outer tank, one end of the resistor is connected with the square metal sensing sheet, the other end is connected with the outer tank, one end of the cable is connected with the resistor, the other end is connected with the voltage tester, and the voltage display is connected with the voltage tester and is used for calculating and displaying a voltage value of the high voltage conductor for the outer tank. The voltage measurement device is advantaged in that through measuring the resistor voltage, the voltage value of the high voltage conductor in the combined electric gas insulation device for the outer tank can be acquired, and the purpose of monitoring an operation state of a high voltage transmission line in real time can be realized.
