| Zusammenfassung: | The invention relates to a resistor disc screening method and device and screening equipment. The method comprises the following steps: under the condition that a first sequence impact current is applied to a current batch of resistor discs in a whole batch of resistor discs, performing defect detection on the current batch of resistor discs to obtain a first screening qualification rate; under the condition that the second sequence impact current is applied to the current batch of resistor discs, performing defect detection on the current batch of resistor discs to obtain a second screening qualified rate; under the condition that the third sequence impact current is applied to the current batch of resistor discs, defect detection is carried out on the current batch of resistor discs, and the third screening qualified rate is obtained; and determining that screening of the resistor discs for the direct-current lightning arrester is completed until all batches of resistor discs in the whole batch of resistor |
