The invention discloses a contact constant-temperature heating device for an electric switch machine. The contact constant-temperature heating device comprises a contact cover, a constant-temperature heating belt and a cover plate, the top of the hollow contact cover is provided with a transparent cover plate which is horizontally distributed; a constant-temperature heating belt mounting groove with a top opening is formed in the upper part of the peripheral frame of the contact cover in a surrounding manner; an annular constant-temperature heating belt is arranged in the constant-temperature heating belt mounting groove in a surrounding manner; and a contact cover inner cavity of the contact cover is used for placing a switch machine movable contact and a switch machine static contact on the top of a switch machine contact seat of the existing electric switch machine. The device is scientific in structural design, can heat the switch machine movable contact and the switch machine static contact (specifically a movable contact ring and a static contact piece) in the electric switch machine, so that the ambient temperature around the switch machine movable contact and the switch machine static contact is kept at a relatively high temperature, the frosting problem in a cold and humid environment is effectively prevented, the normal operation of the indication circuit of the switch machine is guaranteed, and great production practice significance is achieved.
本发明公开了一种电动转辙机用接点恒温加热装置,包括接点罩、恒温加热带和盖板;中空的接点罩顶部,设置有水平分布的、透明的盖板;接点罩的四周边框上部,环绕地设置有顶部开口的恒温加热带安装槽;恒温加热带安装槽内,环绕地设置有环形的恒温加热带;接点罩的接点罩内腔,用于放置现有电动转辙机的转辙机接点座顶部上的转辙机动接点和转辙机静接点。本发明结构设计科学,能够对电动转辙机中的转辙机动接点和转辙机静接点(具体是动接点环和静接点片)进行加热,使得转辙机动接点和转辙机静接点的周围环境温度保持在较高的温度,有效防止在寒冷、潮湿环境中出现结霜问题,保证转辙机表示电路的正常运行,具有重大的生产实践意义。
