Abstract

The invention is a impacting current testing device based on nonlinear metal oxide resistance plate, which includes a energy storing component arranged in the metal frame and waveform forming resistance, inductance, the conductive metal boards connects the electrodes of the capacitance together, the high voltage end of the capacitance is connected to the discharging device, the discharging device is connected to the high voltage end of testing electrode on the transmitting mechanism of the resistance plate, the transmitting mechanism uses step-by-step motor to drive the metal turnplate, when the resistance plate rotates the position of the clamping piece mechanism, the metal turnplate stops automatically, the piece clamping mechanism act automatically. When the piece clamping mechanism measures that there has resistance plate, the discharging gas is connected automatically, completes one discharging process. The invention has merits of automatic localization, automatic discharging, and automatic grounding functions.

Description

Technical field [0001] The invention belongs to a non-linear metal oxide resistor piece electrical performance testing device, and particularly relates to a non-linear metal oxide resistor piece impulse current testing device used in a metal oxide arrester (MOA). Background technique [0002] The electrical performance test device for non-linear metal oxide resistors mainly refers to the 8 / 20μs impulse current and 2ms square wave generator, test unit, resistor transport mechanism and control unit. There are two types of resistance strip transport mechanisms for commonly used test devices: one is to use transmission chains to transmit resistance strips. The working process is to place the resistance strips on an insulating pallet with equidistant holes in advance, so that the electrodes used for testing touch Then put the resistor chip support board on the transmission chain, and the transmission chain is dragged by the motor. When the displacement sensor detects the resistor chip...
