Embodiment 1

[0028] See attached figure 1 , the railway catenary power outage operation safety protection system includes a grounding line (not shown), a high-voltage electrical inspection device 1, an electric mechanism 2, a grounding detection mechanism 3, a first video monitoring device (not shown), a second video monitoring device ( not shown) and remote control device 4. The grounding line includes a fixed grounding electrode, a high-voltage grounding switch, copper wires and their connecting clamps. The high-voltage grounding switch is set on the copper wire, and the grounding line is used to ground the catenary wire and catenary cable of the catenary. as attached figure 1 As indicated by the arrow in , the high-voltage electroscope 1 receives detection instructions from the remote control device 4 to detect whether the catenary is carrying voltage. Wherein the high-voltage electrometry device 1 detects whether the catenary has voltage after the power failure of the catenary, and ...

Embodiment 2

[0032] See attached figure 2 , In another embodiment of the present invention, the railway catenary power outage operation safety protection system includes a grounding line, a high-voltage electroscope 1, a motor mechanism 2, a grounding detection mechanism 3, a first video monitoring device, a first video monitoring device and Remote control device4. The grounding line includes a fixed grounding electrode, a high-voltage grounding switch, copper wires and their connecting clamps. The high-voltage grounding switch is set on the copper wire, and the grounding line is used to ground the catenary wire and catenary cable of the catenary. The high-voltage electroscope 1 receives the detection command from the remote control device 4 to detect whether the catenary has voltage, and when it detects that the catenary does not have voltage after the catenary is powered off, it issues an instruction to the motor mechanism 2 to close the high-voltage grounding switch ; When it is dete...

Abstract

The invention provides a power-cut work safety protection system for a railway overhead line system.The power-cut work safety protection system for the railway overhead line system comprises grounded lines, high-voltage electricity testing equipment, an electric mechanism, a grounding detection mechanism, first video monitoring equipment, second video monitoring equipment and remote control equipment.The power-cut work safety protection system for the railway overhead line system is safe, economical and rapid, and can be applied to substations, switching stations and section posts of railway lines and special lines with frequent work of electrified railway loading and unlocking trucks; the grounded lines of the overhead line system can be switched on or switched off under remote control, so that manual operation procedures are reduced, and safety measure layout time is shortened; meanwhile, grounding reliability of grounded circuits is ensured through corresponding detection equipment, so that work safety is greatly improved.

Description

technical field [0001] The present invention generally relates to a safety protection system for electrified railway catenary power outage operations, including feeder circuits of substations, switching stations, and partition stations, as well as a method and system for safety protection for power outage operations in places with frequent operations on special lines for electrified railways. Background technique [0002] The catenary is a special form of transmission line erected along the railway line to supply power to electric locomotives. It is composed of contact suspensions, support devices, positioning devices, and pillars. The contact suspension includes components such as contact wires and catenary cables. The contact suspension is erected on the pillar through the supporting device, and its function is to transmit the electric energy obtained from the traction substation to the electric locomotive. [0003] During the maintenance of catenary lines of electrified ...
