The invention relates to a large oil power transformer maintenance process in a power system, in particular to a method for replacing a butterfly valve of a transformer through oil-carrying vacuumizing. The method is reasonable in design, and a vacuum pump is used for vacuumizing, so that replacement work of the butterfly valve can be completed while the transformer does not release oil completely, time for the whole replacement process is saved, outage time can be reduced effectively, power sale quantity is increased, economic loss is lowered, working efficiency is improved, waste of manpower resources is reduced, manpower resource expense is saved, and transport expense caused by transporting of large equipment is reduced.

The invention relates to a 10KV equipped temporary wiring structure and a wiring method, belonging to the technical field of power supply system wiring. Technical solution: hook the bare wire bayonet (14) on the top of the metal hanger (1) to the bare wire (11) of the 10KV main line; pull the wire expansion wrench (4) on the insulated wire expansion wheel (3) ), the insulated wire (6) is clamped between the fixed wheel (2) and the insulated wire expansion wheel (3), and the insulated wire (6) can be tightened by turning the insulated wire expansion wheel (3); at 10KV When the main line is not powered off, the bare wire (11), the metal hanger (1), the insulated wire (6) and the electrical equipment form a temporary power channel to play the role of temporary wiring. The invention is easy to operate, simple, safe and reliable, and plays the role of temporary wiring when the main line is not powered off, and it will be processed together when the main line has a power outage plan, which greatly reduces the number of power outages, reduces losses, and improves electricity sales and power supply reliability.

The invention discloses a multi-functional electrical equipment lifting hold lever tool which relates to a special tool for lifting and hanging, so as to solve the problems that an existing lifting hold lever occupies a large area and cannot be fixedly arranged on an electrical equipment support uprightly, the load bearing capability cannot be adjusted, the overhaul of transformation equipment is not adapted to, and the electrical equipment cannot be lifted when part of a transformation substation powers off. The lower end of a main support is connected with a base, and the top end of the main support is fixedly connected with the low position end of an oblique beam; one end of a traction oil wire rope is wound on a grinder, and the other end of the traction oil wire rope is wound on a fifth pulley through a first pulley, a second pulley, a third pulley and a fourth pulley; the first pulley is fixedly arranged on a first pulley frame; the second pulley is fixedly arranged on the base; the third pulley is fixedly arranged below the oblique beam; the fourth pulley is fixedly arranged below the high position end of the oblique beam; a lifting hook is arranged on the fifth pulley; a plurality of shackles are staggered up and down along the inner side surface and the outer side surface of the main support; and one end of a reinforced oil wire rope is wound on the grinder, and the other end of the reinforced oil wire rope is wound on a sixth pulley. The multi-functional electrical equipment lifting hold lever tool is used for the overhaul of the transformation equipment.

The invention discloses a high voltage isolator electrified oil lubricator. The main body of the oil lubricator is an insulating box lubricator (1) with an insulating rod (2), an oil outlet nozzle (41) on the box lubricator (1) is connected with an oil outlet pipe (4) inside the box lubricator; the oil outlet pipe (4) is provided with a fixed piston (5) and a moveable cylinder body (6); the bottom surface of the moveable cylinder body (6) is provided with an oil inlet hole (61); an oil inlet spring (62) and an oil inlet steel ball (63) are arranged between the fixed piston (5) and the oil inlet hole (61); the piston (5) is provided with an oil outlet (51); an oil outlet spring (52) and an oil outlet steel ball (53) are arranged between the oil outlet hole (51) and the oil outlet pipe (4);a pull rod (7) arranged outside the moveable cylinder body (6) is connected with a lever (8); and the lever (8) is connected with an oiling handle (3) through an insulating pull rod (10). The oil lubricator completes oiling lubrication to a high voltage isolator under the electrified state, brings the convenience to state maintenance, and reduces abnormal power failure.
