I. Management regulations
    According to the Q/GDW 168-2008 "Transmission and Transformation State Inspection and Repair Test Regulations", the grounding knife gate is routinely inspected every three years.
Second, the role of the grounding knife
    When the equipment needs power failure maintenance, after the circuit breaker and disconnector are disconnected and the experience is electric, after confirming that there is no electricity, close the grounding knife gate, and you can safely carry out maintenance. The role of the grounding gate here is:
    1 Discharge the service equipment.
    2 Prevent accidental power transmission in the maintenance equipment. It is dangerous to the maintenance personnel.
Third, inspection standards
    (1) The grounding knife gate is free of rust.
    (2) The three-phase synchronization of the grounding knife gate meets the requirements of the equipment specification.
    (3) After the closing, the three-phase contact is in good contact, the insertion depth and the verticality of the left and right contacts meet the requirements, and the length of the closing positioning bolt meets the requirements.
    (4) After the opening, the three-phase linkage position is correct, and the length of the opening positioning bolt meets the requirements.
Fourth, the inspection process
    Preparation work
(1) Before and after the inspection, detailed and comprehensive investigation and analysis of the grounding knife gate installation conditions, operation conditions, fault conditions, defect conditions and recent test and test of grounding knife gate equipment are carried out to determine the comprehensiveity of the grounding knife gate. situation.
    (2) Prepare necessary maintenance tools, spare parts and materials. Such as: insulation ladder, seat belt, combination wrench, conductive paste, protective gloves, etc.
    2. Inspection steps
    (1) Check the surface of the grounding gate: Check the grounding knife for corrosion. If it is polished, apply conductive paste.
    (2) Three-phase synchronization check of the grounding knife gate: It is divided into multiple times to check whether the three-phase separation is consistent.
    (3) Closing position inspection: Check the three-phase contact is in good contact, the insertion depth, the verticality of the left and right contacts meet the requirements, and the length of the closing positioning bolt meets the requirements.
    (4) Inspection of the opening position: the three-phase linkage position is correct, and the length of the opening and positioning bolts meets the requirements.
Five, matters needing attention
    (1) When climbing, the ladder should be protected against dumping (supported by someone or tied with a rope).
    (2) Wear protective gloves when applying conductive paste.
