A catenary line fault intelligent removal equipment, system and method thereof

Abstract

The invention discloses contact net line fault intelligent cutting equipment and a system and a method. The contact net line fault intelligent cutting equipment comprises a high-voltage device and a control protective device. The high-voltage device is arranged on contact net branch lines and used for switching a circuit of the contact net branch lines and detecting a state of the circuit, the control protective device is connected with the high-voltage device and used for judging according to the circuit state which is obtained by detecting of the high-voltage device so as to obtain whether the circuit state is normal or not, and therefore, the high-voltage device is switched and controlled. The high-voltage device and the control protective device are arranged on the contact net branch lines, the aim that when the contact net lines is broken down, the contact net branch lines can be automatically cut from a main line is achieved, and the fault branch lines can be precisely confirmed. The contact net line fault intelligent cutting equipment is safe in performance and stable, can facilitate working staff rapid processing of line faults, and greatly improves efficiency of power supplying management working.

Description

technical field [0001] The invention relates to the field of power control of railway electrification systems, in particular to a catenary line fault intelligent removal device, system and method thereof. Background technique [0002] With the ever-growing demand for energy in the national economy and the increase in coal and other energy sources in railway transportation, the branch lines of catenary lines are constantly being added. However, due to the unreliable power supply, frequent power supply failures of catenary branch lines occur After the occurrence, it will directly affect the power supply of the main line, resulting in a wide range of influence and a long power outage, which has become a problem to ensure smooth power supply. [0003] At present, the electrical separation between the main line and the branch line of the domestic electrified railway catenary basically adopts isolating switches or load switches. However, the isolating switch can only be opened an...

AI Technical Summary

Problems solved by technology

However, the isolating switch can only be opened and closed in the no-load state, and although the load switch can cut off the normal load current, it cannot cut off the circuit when the line short-circuit fault occurs. The branch lines are connected. When a branch line fails, it cannot be separated from the main line quickly, so the whole main line will be cut off and the transportation will be interrupted. The resulting blackout area will be large.
