The invention provides a roof insulation strengthening method for a harmonious electric locomotive. The method comprises the following steps that: S1, roof paint and an old coating are cleaned; S2, the roof of the locomotive is sprayed with insulating paint; S3, insulation reinforcement is carried out on a vacuum main circuit breaker; S4, insulating sheaths are additionally arranged at the top andthe bottom of a roof high-voltage electric appliance; and S5, insulation protection is carried out on a roof high-voltage circuit connecting line by adopting a heat-shrinkable high-voltage sleeve. According to the roof insulation strengthening method for the harmonious electric locomotive, all components of the roof and high-voltage electric appliance components in the locomotive can be insulatedand protected wholly, all the high-voltage electric appliance components in the locomotive are protected according to protection categories, and a good insulation effect that insulation protection iscompletely covered as much as possible is achieved.

    本发明创造提供了一种和谐型电力机车车顶绝缘加强的方法,包括如下步骤:S1:将车顶油漆及旧涂层进行清理、清洁;S2:车顶绝缘漆喷涂:S3:对真空主断路器进行绝缘加强;S4:车顶高压电器顶部和底部加装绝缘护套;S5:对车顶高压电路连接线采用热缩高压套管进行绝缘防护。本发明创造所述的和谐型电力机车车顶绝缘加强的方法可以集车顶各部件与车内高压电器部件绝缘防护于一体,对机车内各高压电器部件按防护类别进行防护,达到绝缘防护尽可能全覆盖的良好绝缘效果。
