①Before the simulation training starts, the person in charge directs the members of the work class to adjust the height of the GW-type isolation and the spacing of the ceramic columns to the requirements of the corresponding voltage level according to the training plan.

②The ground coordinators use infrared thermal imaging equipment to measure the temperature of the hot spot in advance to ensure that the temperature will not burn the operator. They measure it every five minutes and measure it three times in a row. There should be no obvious difference in the temperature between the three times. After reporting that there is no abnormal fluctuation in humidity, the live treatment operation can be started.

③ The equipotential electrician chooses the position of the vertical ladder, directs the ground electrician to erect the insulating lift at a suitable position near the heating point, and fix the four-sided pull rope.

④ The equipotential electrician wears a full set of qualified shielding clothing and enters the electric field along the insulating lift to the connection point of the heating knife clamp. During the process of entering the electric field, the range of body activities should be minimized, and the range of proficiency in movements is small. The moment of contact with the charged body, the movements are quick and fast, and the hands are the first to touch.

⑤ When the equipotential electrician enters the electric field, the guardian should monitor the action of the equipotential electrician and the dangerous distance from the charged body in a suitable position throughout the process, and command and guide in time.

⑥The equipotential electrician takes out the temperature wax and puts it on the clamp to be processed. If the temperature wax does not melt, spray it with the rust removal spray on the connecting bolts of the clamp to be processed. After spraying, use an ordinary cloth with good water absorption to wipe off the excess rust remover on the wire clamp to prevent it from flowing to the insulating porcelain pillars and other places.

⑦The equipotential electrician takes out the wrench and tightens all the bolts of the clamp. Special attention should be paid during the tightening process. The upper and lower double wrenches should be used, and the torque used by the operator should form a balanced force couple through the upper and lower wrenches. A single wrench should not be used for tightening, which will cause the ceramic column of the knife gate to bear the longitudinal force. Torsion and horizontal bending forces cause mechanical damage to the knife switch.

⑧The person in charge of the work can check the operation steps around the outgoing personnel, and can closely guide and correct the irregular and dangerous actions of the outgoing personnel.

⑨The person in charge directs the equipotential electrician to withdraw from the strong electric field.

⑩The person in charge of the work directs the coordinating personnel on the ground to use infrared thermal imaging equipment to measure the temperature of the hot spot, and measure it every five minutes, and measure it three times in a row. The person in charge reports.

⑪If the temperature does not drop significantly, the person in charge instructs the equipotential electrician to enter the strong electric field again as required to reach the working position, use #0 sandpaper to clean the oxide layer on the upper surface of the wire clamp and the lower surface of the knife gate aluminum plate, and take out the emergency wire The clip is installed between the wire clip and the aluminum plate of the knife gate.

⑫ The person in charge instructs the equipotential electrician to withdraw from the strong electric field, and instructs the coordinating personnel on the ground to measure the temperature of the hot spot with an infrared thermal imaging instrument, measuring once every five minutes, and measuring three times in a row. The measured temperature should be significantly lower than that before the treatment, and There should be no significant difference in the three temperatures, and report to the person in charge of the work.
