Abstract

The invention discloses a tail end matching resistor used for GIS. The resistor comprises a matching resistor component, a resistor adjusting component and an insulation flange. The matching resistorcomponent is arranged on the insulation flange. The resistor adjusting component is arranged on the insulation flange. The resistor adjusting component makes a matching resistor in the matching resistor component access a loop. The resistor adjusting component can replace the matching resistor in the matching resistor component. A dynamic sealing component and a fastening component are arranged between the insulation flange and the resistor adjusting component. A first screwed hole is arranged on the insulation flange. The first screwed hole on the insulation flange adapts to a threaded hole on a GIS tank. The diameter of the insulation flange adapts to the diameter of the GIS tank. The butt joint of the insulation flange and the GIS tank can be ensured. By using the tail end matching resistor used for the GIS, under the condition that the GIS tank is not dismounted, the resistor is matched and the matching resistor is replaced, the edge surface distance of the matching resistor can beincreased, and the edge surface insulation strength of the matching resistor can be improved.

Description

technical field [0001] The present application relates to the field of power systems, in particular to a terminal matching resistor for GIS. Background technique [0002] GIS (that is, gas-insulated metal-enclosed switchgear) is widely used in power systems. During the operation of GIS, GIS will inevitably suffer from lightning impulse voltage and ultra-fast transient overvoltage. To carry out the impulse test, the impulse voltage needs to be measured at the same time. [0003] Since the amplitude and frequency of the impulse voltage are often high, the capacitance and inductance in the transmission line cannot be ignored, so the transmission of the impulse voltage needs to be considered by a distributed parameter circuit. In order to keep the waveform of the impulse voltage at the end of the GIS from changing, it is necessary to install a matching resistor at the end of the GIS. [0004] At present, the method of installing matching resistors at the end of the GIS is to d...
