The invention relates to an anti-icing composite contact line and temperature monitoring device for an electrified railway. Belongs to the technical field of electrical control. The problem that the surface of the contact line of the electrified railway is frozen is mainly solved. The contact wire is mainly characterized in that an insulating electric heating wire is arranged in the contact wire along the axial direction to form a composite contact wire; and two ends of the insulating heating wire are radially led out from two ends of the contact wire. And the temperature monitoring device is provided with a heating power supply and a temperature monitoring device. When the surface temperature of the contact wire is lower than the freezing point, the heating power supply electrifies and heats the insulating heating wire to a safe temperature and then automatically stops, and the surface temperature of the composite contact wire is always kept above the freezing point, so that the surface of the contact wire is prevented from being frozen. The method is simple, safe, reliable and high in intelligent degree, and can be widely applied to anti-icing technology upgrading and transformation of the electrified railway high-voltage contact line.
本发明的名称为“电气化铁路防结冰复合接触线及温度监控装置”。属于电气控制技术领域。它主要是解决电气化铁路的接触线表面结冰问题。它的主要特征是:在接触线内沿轴向设有绝缘电热丝,构成复合接触线;绝缘电热丝两端从接触线两端径向引出。温度监控装置配有加热电源和温度监测装置。当接触线表面温度低于冰点时,加热电源对绝缘电热丝通电加热,至安全温度后自动停止,复合接触线表面温度始终保持在冰点之上,从而防止接触线表面结冰。本发明简单安全可靠、智能化程度高,可广泛应用于电气化铁路高压接触线的防结冰的技术升级与改造。
