▎ 摘　　要

NOVELTY - A graphene oxide mixed liquid automatic spraying device comprises device main body (1) which is provided with connector (2), nozzle (3), front end of a handle (5), supporting rod (6), and groove. The connector is set with nozzle. The handle is set on the connector. The groove is provided on the device main body. The supporting rod is set in the groove. USE - Graphene oxide mixed liquid automatic spraying device. ADVANTAGE - The device is simple and convenient to use, has quick coagulation function, improves conducting rate, shortens maintenance time, and has corresponding phase line color. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for electrical device maintenance comprising: (A) separately preparing 3 solution of 10-15 wt.% graphite, 8-20 wt.% ethanol, 8-25 wt.% ethylene glycol, 18-25 wt.% copper sulfate, 2-8 wt.% lemon yellow, 20-42 wt.% copper, 10-15 wt.% anti-cracking powder, 5-15 wt.% dimethyl polysiloxane, 0.1-5 wt.% brightener, 1-5 wt.% defoamer, 0.1-3 wt.% anti-settling agent, 0.1-5 wt.% tackifier, and balance distilled water as first, second, and third solutions, filling with compressed gas, and filling into bottle; (B) taking 45-65 wt.% graphite, 6-20 wt.% ethanol, 8-25 wt.% ethylene glycol, 4-25 wt.% copper sulfate, 2-12 wt.% copper, 1-15 wt.% anti-cracking powder, 5-15 wt.% dimethyl polysiloxane, 0.1-5 wt.% tackifier, defoamer, anti-settling agent, and remaining distilled water as fourth solution, filling with compressed gas, and filling into bottle; (C) taking accelerator solution and filling into bottle with compressed gas as fifth step; (D) testing; (E) dismantling busbar, contacting with P800 sandpaper, grinding welds and impurities, and fine grinding with P1200 sandpaper; (F) brushing; (G) shaking bottle with graphene mixture; (H) spraying with fourth solution; (I) spraying with fifth liquid and rapid curing; (J) spraying with fourth and fifth solutions and curing for 5 minutes; (K) grinding, spraying with fourth solution; (L) spraying with first solution to complete A-phase busbar maintenance; (M) repairing B-phase busbar same as A-phase busbar; (N) repairing C-phase busbar same as A-phase busbar; and (O) re-installing busbar, putting bolt, measuring, observing, power operation, and recording.
