Problems solved by technology

As the only man-carrying equipment in rail transit, the locomotive’s stability, reliability, and maneuverability are actually related to the safety of personnel, especially when switching between line power supply and static adjustment maintenance, it must be simple, convenient, and reliable. When switching, manual operation of multi-position switches is used. This type has a large waste of labor, lacks in quick operation, and is easily restricted.

Abstract

The invention discloses a monopole three-position electric disconnecting switch for a locomotive and a using method thereof.The switch comprises a frame body, a first wiring board, a second wiring board, a third lower wiring board, a third upper wiring board, an isolating knife component and an electric operating mechanism, the first wiring board forms a first wiring position, the second wiring board forms a second wiring position, a third wiring position is arranged between the third lower wiring board and the third upper wiring board, each of the first wiring board, the second wiring board, the third lower wiring board and the third upper wiring board comprises a double-layer insulating rod and a wiring board, and the frame body is provided with a plurality of travel switches for detecting the rotation position of the isolation knife component; the method comprises the following steps: operating connection conduction of the first wiring position and the third wiring position; operating the second wiring position and the third wiring position to be connected and conducted; and operating the first wiring position and the second wiring position to be disconnected from the third wiring position in a three-position state. The monopole three-position electric disconnecting switch is small in size and capable of ensuring that three stations are switched in place so as to meet the requirements of locomotives.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to a single-pole three-position electric isolating switch for locomotives and a method for using the same. Background technique [0002] Since the beginning of the 21st century, the construction of urban rail transit with the characteristics of energy saving, fast and large transportation has attracted more and more attention from major cities. Especially in recent years, the construction and development have been rapid and steady. Rapid rail transit and maglev systems have become the top priority of urban construction. As the only man-carrying equipment in rail transit, the locomotive’s stability, reliability, and maneuverability are actually related to the safety of personnel, especially when switching between line power supply and static adjustment maintenance, it must be simple, convenient, and reliable. Manual operation of multi-position switches is used...
