Description
Technical field
The present invention relates to a kind of current transformer part device, specifically a kind of oil-immersed current transformer auxiliary oiling device.
Background technology
Oil-immersed current transformer is one of most important equipment in substation equipment maintenance and repair work area, the quality of its running status, can be directly connected to the stable operation of other each equipment, therefore, in routine duties, the good of necessary strict guarantee oil-immersed current transformer running status.
Oil-immersed current transformer is in running, and mending transformer oil work is an important step, oil-immersed current transformer need the reason of repairing have following some: 1, during oil-immersed current transformer day-to-day operation, the normal consumption of transformer oil; 2, detecting due to regularly oil sample can be extracted to oil-immersed current transformer, so when having extracted oil sample, transformer oil need be mended in time; 3, the oil impregnate phenomenon of oil-immersed current transformer, can cause the minimizing of transformer oil mass in oil-immersed current transformer.
Expander on oil-immersed current transformer is an elasticity original paper, and when in instrument transformer, the volume of transformer oil changes, the main volume of expander respective change will occur, and plays volume compensation effect.So, when instrument transformer oil level is not enough, just by expander oil level instruction Timeliness coverage, now, just can need to supplement transformer oil to instrument transformer, rise to normal oil level indicator to make expander.When instrument transformer repairing, need first expander to be risen to assigned address, but because expander is flexible member, there is retraction energy, so need many people when promoting expander or just can complete by crane is auxiliary, time-consuming, effort, take people, workload is large, workflow is loaded down with trivial details, and due to expander unbalance stress during repairing, the flexible of expander does not highly have standard, also can cause repetition repairing, waste resource.
How rapidly, like a cork, exactly in sum, in the repairing process of oil-immersed current transformer, complete repairing work, be the difficult problem that substation equipment maintenance and repair work area faces at present.
Summary of the invention
The object of the invention is the problem in order to solve oil-immersed current transformer repairing difficulty, and a kind of oil-immersed current transformer auxiliary oiling device is provided.
The present invention is achieved by the following technical solutions:
A kind of oil-immersed current transformer auxiliary oiling device, comprise a left side, right two bases, the first tapped through hole is offered at the top of base, first tapped through hole internal thread is connected with stud, stud is fixed with nut (for being fixedly connected with between stud with nut, non-threaded connection), nut overcoat is equipped with reversible ratcheting tool, position above stud top nut is provided with connecting plate, the centre position of connecting plate offers the second tapped through hole, two side positions offer the first bar shaped guide groove along connecting plate y direction, connecting plate is threaded with stud by the second tapped through hole, also Ka Liang is connected between the same side end of two connecting plates in left and right, the both side ends position of Ka Liang offers the second bar shaped guide groove along card beam y direction, the crossover location of the first bar shaped guide groove of connecting plate and the second bar shaped guide groove of Ka Liang is twisted and is connected to fastening bolt (the first bar shaped guide groove on connecting plate can be used for the distance between adjustment two card beam, make two card beams can near or away from, the second bar shaped guide groove on Ka Liang can be used for the distance between adjustment two connecting plate, left and right base, make left and right base, connecting plate can near or away from).
During use, as shown in Figure 6,7, first regulate the distance between the left and right base of this oiling device by the second bar shaped guide groove on Ka Liang, make left and right base just in time be positioned at the both sides of expander and be supported on the instrument transformer platform below expander; Then regulate connecting plate and card depth of beam by rotating ratchet spanner, make its position highly just in time between termination, expander top and expander top surface; Then regulate the distance between two card beams by the first bar shaped guide groove on connecting plate, make Liang Kaliang be stuck in the both sides of expander top head bottom part and clamp, fastening bolt is tightened after all adjusting in position, to fix each structure of this oiling device; Finally, synchronous axial system two ratchet spanneres, stud also and then rotates rising, makes two card sill bolts move expander and slowly rises, and after expander is lifted, just can carry out oiling work.
Further, also extended vertically upward on the first tapped through hole of base top have the threaded sleeve be threaded with stud.Threaded sleeve can strengthen the stability of strutting system of stud, and whole equipment safety is further improved.
The present invention is novel in design, structure is simple, can flexible be fixed on instrument transformer, ensure that expander stretches uniform force, change the state needing more than many people in the past when oiling being carried out to instrument transformer or even have mechanical back work, real has liberated manpower, save material resources, there is advantages such as saving time, laborsaving, economic, safe, be worth of widely use.
