    Abstract: The paper first analyzes why the 1 000 kV UHV shunt reactor newly put into operation generates acetylene through disassembly inspection in the factory, and the cause of it is that the unreliable connection between the grounding strip and the grounding wire of the magnetic shunt leads to unreliable magnetic shunt grounding which makes contact discharge happen. Therefore, a new grounding mode of shielding pipes on the side of magnetic shunt clamps is proposed. It changes the grounding mode from the contact grounding between shielding pipes and clamps to using grounding wires to connect shielding pipes and clamps that have been insulated. This method can avoid unreliable contact caused by vibration,provide great reference for the production, operation and maintenance of UHV shunt reactors.
    Key words: ultra high voltage; shunt reactor; magnetic shunt; grounding
