Description

Technical Field

[0001] This utility model relates to the field of intelligent surge arrester technology, and in particular to an intelligent surge arrester for electric locomotives. Background Technology

[0002] With the rapid development of my country's electrified railway system and the continuous increase in train speed, higher requirements have been placed on the safe and stable operation of railway equipment. Intelligent monitoring is one of the effective means to ensure its safe operation. The 27.5kV AC gapless zinc oxide surge arrester (MOV) is an important protective device widely used in the railway system and plays a vital role in the safe and stable operation of trains.

[0003] However, in recent years, surge arresters in railways have frequently experienced operational failures. In addition to common faults such as aging, dampness, dirt, and overvoltage, the failure of surge arresters under the action of high-order harmonic voltages is becoming increasingly serious due to the mixed operation of multiple trains on railway lines. When the train network is mismatched and causes resonance in the traction network, the surge arresters may fail.

[0004] In the existing technology, monitoring is carried out by using a leakage current sensor built into the surge arrester. This requires high detection accuracy from the current sensor, and temperature also has a certain impact on the detection accuracy, resulting in poor detection accuracy. Utility Model Content
