Summary: | The utility model discloses a DC stringing locking switch device, which aims at controlling electrical contact caused by that underground persons contact a stringing and the corrosion for a pipeline and an armoured cable caused by leakage current generated by empty consumption of electric energy. The utility model has the technical proposal that the device comprises a stringing, a locomotive, a locomotive running orbit and a control power source and is characterized in that a main control box is arranged between the locomotive and the stringing, and the main control box is connected with a display. A locomotive driving chamber is provided with a signal transmitter, a signal is transmitted to the stringing through a charge coupling mechanism through the signal transmitter, and the main control box, the display, the charge coupling mechanism and the signal transmitter are connected and form a closed circuit through the stringing, the locomotive and the locomotive running orbit. Accidents, such as locomotive blindgating, head contact, upper arm resistance, etc., are solved and reduced through the technology, underground work persons' safety is ensured, and saved electricity cost for each year can reach 200 thousand yuan. |
