Abstract

The invention discloses a railway disconnecting switch opening and closing monitoring system which comprises an angle acquisition device, a light source optical fiber, a signal processing controller and a receiving optical fiber. The signal processing controller controls the light source optical fiber to irradiate light into the angle acquisition device, then the receiving optical fiber receives the reflected light, and the reflected light is transmitted to the signal processing controller for photoelectric conversion; the rotating angle information of a moving contact of a railway disconnecting switch is converted into a readable voltage signal through photoelectric conversion, so that the relation between the rotating angle of the moving contact of the railway disconnecting switch and an output voltage value is obtained, namely the opening and closing angle of the railway disconnecting switch can be detected. The calculated rotation angle information of the moving contact of the railway disconnecting switch is sent to a monitoring center of a railway related department through wireless transmission, so that the related operators can conveniently confirm the switching-on and switching-off condition of the railway disconnecting switch, and then switching-on and switching-off monitoring on the railway disconnecting switch is realized.

Description

technical field [0001] The invention relates to the field of railway isolating switches, in particular to a monitoring system for opening and closing of railway isolating switches. Background technique [0002] The railway isolating switch is one of the indispensable electrical equipment in the railway power supply system. It is a kind of high-voltage isolating switch and plays a role in ensuring the safety of power supply. It is necessary to confirm the opening and closing status of the isolating switch during the opening and closing operation of the high-voltage isolating switch, so as to avoid operating accidents caused by improper opening and closing. When it is in the closing position, the moving contact should have a sufficient cutting depth to ensure that the contact area meets the requirements, but it is not allowed to close too much. It is required that the moving contact has a gap of 3 to 5 mm from the base of the static contact, otherwise the closing is too much ...
