Abstract

The invention belongs to the technical field of isolating switches, and particularly relates to a high-voltage isolating switch for railway power supply lines. The switch comprises a fixing frame, a first insulating column is fixedly installed at the top of the fixing frame, a first transverse plate is fixedly installed at the top end of the first insulating column, a locking mechanism is arrangedat the top of the first transverse plate, the locking mechanism comprises a fixing plate, the bottom of the fixing plate is fixedly connected with the top of a first transverse plate, a first slidinghole is formed in the fixing plate, a clamping block is slidably mounted in the first sliding hole, a second insulating column is fixedly mounted at the top of the fixing frame, a second transverse plate is fixedly mounted at the top end of the second insulating column, a mounting frame is rotatably mounted at the top of the second transverse plate, and a feeler lever is rotatably mounted on themounting frame. The isolating switch is high in practicability, when the isolating switch is switched on, the situation that the isolating switch is switched off due to external force is avoided, theisolating switch is safer during switching-off overhaul, and the operation safety of workers is protected.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a high-voltage isolating switch for railway power supply lines. Background technique [0002] With the continuous development of China's economy, railway transportation is playing an increasingly active role in the important means of transportation in China. China's railway construction will enter a golden period, and high-speed rail and bullet trains have become the main means of transportation for travel. The safety and reliability of the power supply lines that provide power for electrified locomotives are becoming more and more important. With the advent of the high-speed rail era, facing the increasingly strong market demand, the railway traction power supply lines implement segmented power supply, and the railway traction power supply lines implement segmented power supply. Sectional power supply, each section of power supply line is 10-20 kilometers long, becaus...
