Further improvement of the present invention is: fuel outlet and the nut size thereof of described connecting head and the pullover cover hole dimension of nut and different model are corresponding.
Further improvement of the present invention is: sealer and connecting head, connecting head are with transformer fuel outlet respectively by being threaded, and described connecting head upper and lower is equipped with internal thread, and the internal thread on top is connected with the outside thread of transformer fuel outlet; The top of described sealer is provided with the outside thread be connected with the internal thread of connecting head bottom.
Owing to have employed technique scheme, the technological progress acquired by the present invention is:
The present invention drains the oil to transformer, oil holder can be positioned on ground, and the flexible pipe access oil holder connected by the side pipe on sealer, carries oil holder aloft without the need to staff or lift oil holder on the ground, save muscle power, reduce labor strength.
Use apparatus of the present invention to carry out transformer Oil drain operation, only need a staff to complete to install transformer drain the oil device, unscrew fuel outlet nut and connect the operation of oil, saved labour force, improve working efficiency.
The present invention is in the process of draining the oil, and namely oil flows to transformer device of draining the oil from transformer and flows into the process of oil holder again, and omnidistance sealing, the oxygen in oil discord air and contact with moisture, fundamentally ensure that the insulating property of oil.
The nut size of the transformer produced due to different manufacturers often in fuel outlet size and fuel outlet is all different, the connecting head that the present invention is arranged and the pullover cover hole dimension of nut corresponding with fuel outlet nut size, so that the present invention goes for the fuel outlet of different model, there is applicability widely.
Disassembly and assembly of the present invention are convenient, low-profile, are convenient to that electrician personnel are daily to carry.
The cone that nut of the present invention is pullover and cylindrical body are sealed and matched with the conical section of the conical through hole of sealer and cylindrical section respectively, and sealer can by oil seal in sealer, and oil can not be spilt along nut is pullover.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details:
Transformer is drained the oil device, comprise the Oil Guide flexible pipe for Oil Guide and oil holder, also comprise connecting head 1 that device fuel outlet of draining the oil with transformer is connected, be connected with connecting head 1 be a three-port structure sealer 3, be arranged on the nut pullover 2 that being used in sealer 3 unscrews fuel outlet nut, with nut pullover 2 with the use of the speeder wrench 4 being used for rotary nut pullover 2.As shown in Figure 2, sealer 3 is provided with outside thread one three-port structure for outer upper, its endoporus is divided into top, middle part, bottom three part, the outside thread of sealer 3 outer upper is connected with the internal thread of the bottom of connecting head 1, the side of sealer 3 is with side pipe 7, in in the endoporus of sealer 3, superstructure is cylindrical hole, the bottom of endoporus arranges a funnel-like through hole, funnel-like through hole is made up of jointly the conical section on top and the cylindrical section of bottom again, side pipe 7 communicates with the cylindrical hole on the endoporus top of sealer 3 and makes sealer form a three-port structure, side pipe 7 connects described Oil Guide flexible pipe, oil holder is flowed into smoothly to facilitate oil.As shown in Figure 3, nut pullover 2 is made up of two-part: cone 5 and cylindrical body 6, the cone tip part connecting cylinder body 6 of cone 5, cone 5 is sealed and matched with the conical through hole of sealer 3, cylindrical body 6 is sealed and matched with the cylindrical section of sealer 3, but cylindrical body 6 can pass from the passway of sealer 3 bottom the cylindrical section that a section can be stayed sealer 3 bottom.The upper end of cone 5 is provided with a trepanning, cover hole dimension matches with the nut that the oil in transformer fuel outlet blocks up plug screw, here in order to coordinate the fuel outlet nut of the different model of each manufacturer production, the nut pullover 2 of a set of different trepanning model can be set, the lower end of cylindrical body 6 is arranged to square or square, unscrews or tighten nut with fast and easy spanner 4.As shown in Figure 4, speeder wrench 4 is made up of round end and handle two-part, and round end is provided with driving hole, and this driving hole matches with cylindrical body 6, to realize fuel outlet nut to be unscrewed by speeder wrench 4 object by nut pullover 2.Connecting head 1 also can arrange a set of, corresponding with the fuel outlet size of different model, as shown in Figure 1, the upper and lower of connecting head 1 is all provided with internal thread, connecting head 1 is connected with the fuel outlet of transformer by upper part internal thread, and connecting head 1 is connected with the outside thread on sealer 3 top by the internal thread of bottom.
Working procedure of the present invention is as follows:
As shown in Figure 5, first assemble transformer and to drain the oil device, choose the connecting head 1 and nut pullover 2 that are applicable to transformer fuel outlet and interior nut size thereof.Sealer 3 is put into by pullover for nut 2, because the funnel-like shape of through holes of nut pullover 2 with the endoporus lower body part of sealer 3 is sealed and matched, nut pullover 2 is just in time stuck in the bottom of sealer 3, but cylindrical body 6 can pass from the passway of sealer 3 bottom the cylindrical section that a section can be stayed sealer 3 bottom.Then connecting head 1 is connected on sealer 3 by the internal thread of its underpart, then device of being drained the oil by transformer is connected on the fuel outlet of transformer by the internal thread on connecting head 1 top.With hand, the cylindrical body 6 of pullover for nut 2 is upwards lifted until the trepanning of the cone 5 felt on nut pullover 2 just in time blocks the nut in fuel outlet.The square of the end of the cylindrical body 6 on nut pullover 2 is entangled with the driving hole on the round end of speeder wrench 4, nut in fuel outlet integrates drain the oil function and oily plugging function, as long as carry out rotating screw cap pullover 2 by the handle rotating speeder wrench 4, nut in fuel outlet is unscrewed, oil will flow out, then pull down pullover for nut 2 and be stuck in sealer 3, oil can flow into sealer 3 along connecting head 1, end opening due to the pullover 2 pairs of sealers 3 of nut plays the effect of sealing, oil can flow out along side pipe 7, the Oil Guide flexible pipe connected by side pipe 7 again flows into oil holder.
