Electric knife switch contact wiping device

Abstract

The invention discloses an electric knife brake contact wiping device, and relates to the field of transformer substation maintenance. The electric knife brake contact wiping device comprises a pedestal and a plastic supporting rod. A retractable brush is slidably connected on the upper surface of the pedestal. A crank rocker mechanism is installed at the tail part of the retractable brush. The crank rocker mechanism is driven by a motor. The bottom part of the pedestal and the rotating shaft of the plastic supporting rod are connected and tightened by a rotating shaft bolt. The same bus of the plastic supporting rod is provided with traction rings. The tail part of the plastic supporting rod is provided with a control switch connected with the motor. A clamping plate is connected on the rotating shaft of the pedestal. A tension spring is arranged between the tail part of the pedestal and the tail part of the clamping plate. The tail part of the clamping plate is downwardly provided with a pull rope which penetrates through the traction rings of the plastic supporting rod. The beneficial effects of the electric knife brake contact wiping device are that the clamping plate and the pedestal clamp a brake mouth in use, and a contact surface oxide layer is polished without damaging a conductive layer and the wiping process is completed so that the whole process is convenient and rapid without any technical requirement for work personnel and can be easily mastered by the work personnel.

Description

technical field [0001] The invention relates to the technical field of substation maintenance. Background technique [0002] Switching operation is an important job for power facility operation and maintenance personnel. During switching operations, it is often found that some spare switches that have not been operated for a long time, due to environmental pollution, the contact of the switch is oxidized or stained, resulting in poor contact between the dynamic and static contacts of the switch, and the contact of the switch is heated or discharged. If it is not dealt with in time, it will seriously affect the safe operation of the equipment. [0003] The traditional methods used by on-site operation and maintenance personnel are: 1. Clean with the brake lever and scrape the contact of the knife switch, but the effect is not obvious. 2. Manually pull and close the knife gate for many times, and use the multiple contacts of the dynamic and static contacts to grind off the d...

Problems solved by technology

During switching operations, it is often found that some spare switches that have not been operated for a long time, due to environmental pollution, the contact of the switch is oxidized or stained, resulting in poor contact between the dynamic and static contacts of the switch, and the contact of the switch is heated or discharged. Phenomenon, if not dealt with in time, it will have a serious impact on the safe operation of the equipment

[0003] The traditional methods of on-site operation and maintenance personnel are: 1. Clean with the brake lever and scrape the contact of the knife switch, the effect is not obvious

2. Manually pull and close the knife gate for many times, and use the multiple contacts of the dynamic and static contacts to grind off the dirty part of the contact. Improper operation will easily cause serious consequences such as damage to the porcelain part of the knife gate bottle or breakage of the pillar porcelain bottle

3. When the scene cannot be handled, immediately stop the operation task, report the emergency defect, and wait for the maintenance personnel to apply for equipment power outage maintenance treatment
