Abstract
The utility model discloses a special oil-filtering joint group for a large-scale transformer. The special oil-filtering joint group comprises three tees, five ball valves and five sets of quick oil-pipe joints, wherein, the three tees, the five ball valves and the five sets of the quick oil-pipe joints are in threaded connection with each other in a series manner; all the components are fixed on a frame; one end of a first tee is connected with a first quick oil-pipe joint through a first ball valve, and two through-ends of the first tee are respectively connected with one through-end of a second tee and one through-end of a third tee through a second ball valve and a third ball valve; the other through-end of the second tee and the other through-end of the third tee are respectively connected with a fourth joint and a fifth joint; and another port of the second tee and another port of the third tee are respectively connected with a second joint and a third joint. The special oil-filtering joint group increases the switching speed among oil drain, filtration, vacuum pumping and oil filling during the general repair of the transformer, reduces the time for connecting an oil-pipe and disassembling the oil-pipe, improves the working efficiency, and reduces the major overhaul time, the oil seepage of the transformer as well as the oil loss in a working field. The utility model has the advantages of simple structure, convenience and practicability, low cost and good effect.
Description
Technical field
The utility model relates to a kind of on-the-spot high-power transformer oil strain special joint group of installing, overhauling of power transformer that is used for.
Background technology
During the power transformer installation and maintenance, transformer oil will shift transformer oil by vacuum oil-filter.Be extracted into oil tank, be extracted into by oil tank that transformer, transformer oil filter, transformer also will vacuumize by vacuum oil-filter by transformer.Connection to oil pipe in the equipment that transformer factory, vacuum oil-filter factory are provided is considered not comprehensive.Can produce a large amount of seepage oil at the dismounting vacuum oil-filter during with oil pipe that transformer is connected, transformer oil in a link such as oil pumping, oil strain because joint sealing is bad, also can seepage oil, contaminated environment.Can have influence on the effect that vacuumizes by poor sealing owing to connect oil connection temporarily, cause the operating time long, the transformer core that surpasses the rules permission is exposed to the airborne time.And during the transformer installation and maintenance, limited time system, during maintenance quite a few time by oil strain, vacuumize, oiling is shared.Maintenance on-the-spot change oil do during pipe the transformer oil on a ground, not only waste is returned environment and is polluted.
Summary of the invention
The purpose of this utility model is: overcome existing in prior technology the problems referred to above, a kind of on-the-spot high-power transformer oil strain special joint group of installing, overhauling of power transformer that is used for is provided.
The purpose of this utility model realizes by following scheme: adopted to be threaded by seamless steel pipe by first threeway, second threeway, the 3rd threeway, first ball valve, second ball valve, the 3rd ball valve, the 4th ball valve, the 5th ball valve and the first quick oil connection, the second quick oil connection, the 3rd quick oil connection, the 4th quick oil connection, the 5th quick oil connection to compose in series.
First threeway described in the utility model, second threeway, the 3rd threeway, first ball valve, second ball valve, the 3rd ball valve, the 4th ball valve, the 5th ball valve and the first quick oil connection, the second quick oil connection, the 3rd quick oil connection, the 4th quick oil connection, the 5th quick oil connection all are fixed on the framework.
First threeway, one end described in the utility model connects the first quick oil connection through first ball valve, first threeway, two straight-through ends in addition links through the go side always of second ball valve, the 3rd ball valve and second threeway, the 3rd threeway respectively, the straight-through end of another of second threeway, the 3rd threeway connects the 4th quick oil connection, the 5th quick oil connection respectively, and second threeway, the 3rd threeway another port connect the second quick oil connection, the 3rd quick oil connection respectively.
After all connecting an elbow, first threeway, two straight-through ends described in the utility model link with second ball valve, the 3rd ball valve respectively again.
Threeway described in the utility model, ball valve and quick oil connection all adopt the DN5-DN200 type.
Drain the oil when the utility model has improved the transformer overhaul, filter, vacuumize, the conversion speed between the oiling, reduced the time that connects oil pipe, tears oil pipe open, increase work efficiency, reduce the major overhaul time, reduce the transformer oil seepage, reduce working site oil loss.The utility model is simple in structure, convenient and practical, cost is low, effective.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is adopted to be threaded by seamless steel pipe by 1,2,3, five the DN50 copper ball valve 4-8 of threeway of three DN50 and the quick oil connection 9-13 of five cover DN50 and composes in series, and is fixed on and forms large-scale power transformer oil strain special joint group on the framework 14.First threeway, 1 one ends connect the first quick oil connection 9 through first ball valve 4, first threeway 1, two straight-through ends in addition links through the go side always of elbow, second ball valve 5, the 3rd ball valve 6 and second threeway 2, the 3rd threeway 3 respectively, another straight-through end of second threeway 2, the 3rd threeway 3 connects the 4th quick oil connection the 12, the 5th quick oil connection 13, the second threeways 2 respectively, the 3rd threeway 3 another port connect second quick oil connection the 10, the 3rd quick oil connection 11 respectively.Above-mentioned all members all are fixed on the support 14.
By high-power transformer oil strain special joint group, can be when the 220KV150000KVA Repair of Transformer (the heavy 40000KG of oil) secondary vacuum oil-filter of 15 tons of per hour filtering of adopting the maintenance of Shangrao electric company branch company being equipped with realize: drain the oil, filter, vacuumize, the former needs of time of oiling (oil level surpasses the iron core top) were above 8 hours/time, realize that designing requirement reduces by 2 hours purpose, now less than 6 hours, before realizing during maintenance because valve, the joint seepage, it is serious to overhaul on-the-spot seepage oil, each oil consumption is greater than 70KG, greatly reduce oil consumption after requiring to transform, reduce 50KG/ purpose of working site oil loss, the work-yard is lossless basically now.
