Detection system and detection method of ground automatic passing split-phase locomotive position

Abstract

The invention discloses a detection system of ground automatic passing split-phase locomotive position. The detection system comprises a contact screen with two subsection neutral sections, current transformers, a high-voltage breaker, an automatic passing split-phase protection measuring and control device, a communication management device, an AC / DC (Alternating Current / Direct Current) power supply and an outdoor switch station box body, wherein the contact screen with the two subsection neutral sections is provided with three anchoring section joints, and each neutral section is provided with the independent current transformer. The invention discloses a detection method of the ground automatic passing split-phase locomotive position. The detection method comprises the steps of detecting that whether the locomotive current is normal or not through the current transformers on the two neutral sections, judging the actual position of the neutral section where a locomotive is located, and using the actual position as the basis of separating and combining operations of an automatic passing split-phase breaker. According to the detection device and the detection method, which are disclosed by the invention, the working principle is simple, the judging is accurate, the detection is not affected by single-locomotive or multi-locomotive traction and can also not be affected by running speed of the locomotive, the detection device and the detection method are suitable for a passenger and freight mixing line and are also suitable for a normal-speed or high-speed railway, and the application is very wide.

Description

technical field [0001] The invention relates to the technical field of traction power supply for electrified railways, in particular to a position detection system and a detection method for an automatic over-the-road camera on the ground. Background technique [0002] Railway transportation is the main artery of my country's economic development. Although my country's railway construction has achieved rapid development in recent years, the current railway transportation capacity still cannot meet the needs of social development, and it is still necessary to expand the scale of the railway network and realize railway modernization. According to the "Medium and Long-term Railway Network Planning" released by the Ministry of Railways in 2008, it is estimated that the operating mileage of national railways will reach more than 120,000 kilometers in 2020. The planned construction of new lines has been adjusted from 16,000 kilometers to 41,000 kilometers, the construction scale ...
