Description

Technical Field

[0001] This utility model relates to the field of power supply technology for urban rail transit, specifically a rigid contact wire insulator cleaning device. Background Technology

[0002] As a crucial component of urban rail transit power supply networks, the overhead contact system is responsible for transmitting electrical energy along the line and directly conducting it to trains. Due to its unique installation characteristics, it requires insulators to suspend and support the contact wires and maintain electrical insulation between the live conductors and the grounding conductors. The performance of the insulators significantly impacts the working condition of the overhead contact system. Besides bearing high voltage and mechanical loads during operation, environmental dust and dirt also have a substantial influence. Long-term accumulation of dust on the insulator surface without cleaning can lead to flashover and insulator breakdown, causing significant operational difficulties.

[0003] Currently, all routine cleaning of insulators in overhead contact line operations is done manually, which consumes a large portion of the time and has limited actual cleaning effectiveness. The inner skirts of pin insulators are not thoroughly cleaned, and the cleaning paper used for manual cleaning is easily soiled, causing secondary pollution to the insulators in subsequent use. The dust generated is extremely harmful to the health of maintenance personnel.

[0004] Therefore, it is necessary to propose a rigid contact wire insulator cleaning device that features continuous cleaning and easy operation. Utility Model Content
