Abstract

The invention relates to a protecting device and method for rail potential. The protecting device comprises a programmable controller and a voltage detecting module, wherein the voltage detecting module which is used for detecting voltage between a steel rail and a protected area is in communication connection with the programmable controller; a connecting piece comprises a first connecting plate, a second connecting plate and a third connecting plate which are connected sequentially; the first connecting plate is opposite to the third connecting plate; a recess-shaped inlaying opening is formed in the second connecting plate; the bottom wall of the inlaying opening faces the direction away from the first connecting plate; and a lock catch plate and a liquid stopping plate which are connected sequentially are arranged on each of the end, which is away from the second connecting plate, of the first connecting plate and the end, which is away from the second connecting plate, of the third connecting plate. By a control cabinet, ventilating and cooling are realized, influence of particulate matter impurities can further be avoided, and the shortcomings that the effects of connection and erection of the connecting piece are lost, troublesomeness of mounting is increased, and maintenance becomes difficult are avoided.

Description

technical field [0001] The invention relates to the technical field of traffic rail potential, in particular to a protection device for rail potential and a method thereof. Background technique [0002] The traction power supply system of urban rail transit adopts overhead catenary power supply, and the running rail is used as the return path. In order to reduce the corrosion of stray currents on civil structural steel bars, steel rails, equipment metal casings and other underground metal pipelines, relatively complete stray current protection measures have been adopted during the construction of rail transit. That is: the DC traction power supply system is designed as an ungrounded system, and the DC power supply equipment is installed in isolation, and the rail is insulated from the ground through an insulating pad to reduce the leakage of stray current. When there is a starting or running train in the power supply section, or a system short-circuit fault occurs, due to t...
