铁路运行中,由于种种原因,经常发生有载调压隔离变压器烧损的故障,对运输安全稳定造成了影响。经过长期生产实践及经验总结,本文提出了改变调压隔离变压器的阻抗电压值,提高变压器的制造质量,从而提高调压隔离变压器的抗短路能力,提升设备运行稳定性的方法,以确保信号供电的安全、可靠。 During the railway operation, due to various reasons, the failure of the on-load voltage-regulating isolation transformer often occurs, which has an impact on the safety and security of the transportation. After long-term production practice and experience, this paper presents a method to change the impedance voltage value of the voltage regulator isolation transformer to improve the manufacturing quality of the transformer, so as to improve the anti-short circuit capability of the voltage regulation isolation transformer and improve the operation stability of the equipment so as to ensure the signal power supply Safe and reliable.
