Preventing & Resolving Catenary Switch Failures in Rail"Faults of catenary isolating switches" are common failures in current traction power supply operations. These faults frequently result from mechanical failures of the switch itself, control circuit malfunctions, or remote control function failures, leading to refusal-to-operate or unintended operation of the isolating switch. Therefore, this paper discusses common faults of catenary isolating switches during current operations and the corresponding handling methods after fault occurrence.1.CommFelix Spark11/10/2025 -

Key Operating Procedures for Opening and Closing Isolating Switches and Handling Interlock FailuresWhen performing switching operations, operating personnel must carefully verify that the circuit breaker is indeed in the open position. For three-pole interlocked isolating switches, all three phases must move simultaneously, with a maximum allowable vertical discrepancy of no more than 3 mm, before any opening or closing operation of the isolating switch is permitted.1. Key Points for Closing an Isolating SwitchFor manual operation, operating personnel should first remove the interlock pin befJames11/10/2025
