Safety method for reaching equipotential of 1000 kilovolt transformer substation in live-line manner

The objective of the invention lies in solving all existing problems, and finding a safety method for reaching the equipotential of a 1000 kilovolt AC EHV transformer station in a live-line manner. An operator wears complete shielding clothes to reach a wire level position from a ground gate-shaped iron support. During climbing, the distance between the operator and a side phase wire remains within the range from 5.9m to 8.0m. The operator enters into a high electric field from the gate-shaped iron support through an insulating carrying tool. In the entering process, the sum of the distance from the operator to the gate-shaped iron support and the distance from the operator to the side phase wire remains within the range from 6.6m to 8.0m. After the operator reaches the side phase wire and contacts with the phase wire, the distance from the operator to the gate-shaped iron support remains within the range from 5.9m to 8.0m, and the distance from the operator to a central phase wire remains within the range from 14.7m to 18m. The method can enables the process that the live-line operator of the 1000 kilovolt AC EHV transformer station reaches the equipotential to be very safe, enables the live-line operation of the 1000 kilovolt AC EHV transformer station to be safe and convenient, and improves the safe and stable operation level of an EHV power grid.
