A method for verifying characteristics of a voltage-regulating lead and related apparatus

Abstract

The application discloses a voltage-regulating lead characteristic verification method and related device, and relates to the field of power equipment. A connecting sleeve pipe drawn from the inlet of the auxiliary oil tank of a transformer is taken as a measurement terminal of a voltage-regulating lead, wherein the connecting sleeve pipe is connected with the terminal plate of the switch selection part and the switch switching part of the connecting line and the connecting split-type tap switch. A target voltage injection device is controlled to sequentially inject multiple voltage values to the target terminal of the transformer according to the voltage injection strategy indication. During the injection of each voltage value, the split-type tap switch is switched to the target gear indicated by the switch switching strategy. The characteristics of the voltage-regulating lead are verified according to the comparison result data of the voltage measurement value and the voltage simulation value of the measurement terminal under the target gear. The measurement values and the simulation values of the voltage-regulating lead of the split-type tap switch under various working conditions and voltage values are compared, and the verification of the design parameters is realized.
