Abstract
The utility model provides a multi-purpose vacuumizing oiling connector. The oiling connector is easy and convenient to operate and practical and used for vacuumzing oiling of an oil charge type current transformer or a voltage transformer. The oiling connector comprises a three-way ball valve and an oiling cap, a connecting part is connected between the three-way ball valve and the oiling cap, a threaded opening of the three-way ball valve is connected to the connecting part, and two ball valves are arranged on the three-way ball valve. An operation rod is arranged on the oiling cap which is connected with the transformer through an internal threaded opening. The multi-purpose vacuumizing oiling connector has the advantages of being easy and convenient to operate and free of oil leakage and equipment contamination and will not contaminate insulating oil.
Description
Technical field
The utility model belongs to electric power construction, substation equipment installing area.
Background technique
The oiling work that vacuumizes of what our unit was used vacuumize fuelling coupling and be mainly used in oil-filled type current transformer and voltage transformer.But in real work, owing to only having a joint, need to first vacuumize, then change joint connecting tube.The degree of vacuum of pipeline the inside cannot ensure like this, may make steam enter in mutual inductor, affects the insulating property of transformer oil, for equipment safety operation brings hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of easy and simple to handle, practical oiling work that vacuumizes for oil-filled type current transformer and voltage transformer.
The technical solution of the utility model is:
A kind of multiplex formula vacuumizes fuelling coupling, comprise tee ball valve and oil filler cap, between tee ball valve and oil filler cap, be connected with link, the silk mouthful of tee ball valve is connected on link, on tee ball valve, be provided with two ball valves, on oil filler cap, with operating stem, oil filler cap is connected with mutual inductor by internal sealing plug.
Vacuumize fuelling coupling according to described multiplex formula, described operating stem top is with " one " font groove, and the bottom of operating stem is connected with the plug of mutual inductor inside.
The beneficial effects of the utility model are: easy and simple to handle, oil-proof, not contaminated equipment, does not pollute insulating oil.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, tee ball valve; 2, link; 3, oil filler cap.
Embodiment
Embodiment
Multiplex formula vacuumizes fuelling coupling and comprises link 2, tee ball valve 1 and oil filler cap 3.
In order to make convenient operation, in oil filler cap 3, install operating stem additional, operating stem top is with " one " font groove, and the bottom of operating stem is connected with the plug of mutual inductor inside.Unscrew operating stem, operating stem leaves inner plug, and oil circuit is opened; If screw operating stem, just oil circuit can be closed.Can oil circuit control by control operation bar, can prevent that like this in erection joint process, oil circuit is opened oil impregnate and contaminated equipment and surrounding environment.
Vacuumize oiling process as described below.
In the time that needs vacuumize oiling, first the safety cover of the pouring orifice on equipment is screwed down, the oil filler cap that multiplex formula is vacuumized to fuelling coupling is arranged on the position of original safety cover and screws up with a wrench.After two ball valves are all closed, one of them ball valve outlet connects vacuum pump, and another connects oil pipe.
In the time that needs vacuumize, first turn operating stem and open the plug of pouring orifice on equipment with screw-driver.Now open the ball valve that connects vacuum pump and vacuumize, now can slowly open the valve that connects oil pipe and utilize the negative pressure in equipment to make oil by oil pipe, in the time that the oil in oil pipe approaches 5-10 centimetres of ball valves, close the ball valve that connects oil pipe and continue to vacuumize.When degree of vacuum meets after demand of technical standard, to open the valve that connects oil pipe and directly carry out oiling, oiling finishes to turn the pouring orifice on operating stem closing device with screw-driver afterwards, takes off multiplex formula and vacuumizes fuelling coupling, loads onto safety cover, and oiling completes.
Claims (2)
1. a multiplex formula vacuumizes fuelling coupling, it is characterized in that: comprise tee ball valve (1) and oil filler cap (3), between tee ball valve (1) and oil filler cap (3), be connected with link (2), the silk mouthful of tee ball valve (1) is connected on link (2), on tee ball valve (1), be provided with two ball valves, oil filler cap (3) is upper with operating stem, and oil filler cap (3) is connected with mutual inductor by internal sealing plug.
2. multiplex formula according to claim 1 vacuumizes fuelling coupling, it is characterized in that: described operating stem top is with " one " font groove, and the bottom of operating stem is connected with the plug of mutual inductor inside.
