Abstract
The utility model relates to a transformer integral body vacuum oil filling device belonging to the field of transformer manufacturing technology. The utility model comprises a vacuum oil filter (1), a vacuum machine set (2), an oil conservator (3), and a transformer body (4). The oil conservator is communicated with the transformer body through a communication pipe, and a capsule is disposed in the oil conservator. The vacuum machine set is communicated with the oil conservator through a pipeline and a valve, thereby a vacuumizing pipeline (8) can be formed. The vacuumizing pipeline is communicated with the capsule in the oil conservator through a branch pipeline and a valve, and a vacuum oil filter is communicated with the transformer. The utility model is advantageous in that by using the transformer integral body vacuum oil filling device and the method thereof, the transformer can constantly stay in the vacuum state during the oil filling process, thereby the enter of air can be prevented, and the quality of oil filling can be guaranteed.
Description
Affiliated technical field:
The utility model relates to a kind of transformer overall vacuum oiling device, belongs to the transformer manufacturing process technology field.
Background technology:
All need injection transformer oil before large oil immersed power transformer is tested and after on-the-spot the installation in factory, can not entrained air in the transformer in the oiling process, otherwise it is flat influence innings discharging water of the breakdown strength of transformer oil and transformer; Electric pressure is high more, and is strict more to the oiling quality requirement.At present, transformer manufactory adopts the process of repairing after the first oiling mostly, and promptly vacuum oil stops to apart from the about 200mm in fuel tank top the time, and transformer is removed vacuum, from the repairing of fuel tank top to the pasta of stipulating till.The disadvantage that this technology exists is: the repairing process is carried out after removing vacuum, and air can be sneaked into transformer inside, and transformer oil quality and transformer insulated test are had a negative impact.
The utility model content:
The utility model purpose provides a kind of transformer overall vacuum oiling device, remain vacuum state in the transformer in the oiling process, avoided entering of air, guaranteed the quality of oiling, improve the quality of products and fail safe, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: transformer overall vacuum oiling device, comprise vacuum oil-filter, vacuum unit, oil conservator and transformer body, oil conservator was communicated with the transformer body by communicating pipe, be provided with capsule in the oil conservator, the vacuum unit is communicated with oil conservator by pipeline, valve, constitute vacuum-pumping pipeline, vacuum-pumping pipeline is communicated with by the interior capsule of branch road, valve and oil conservator, and vacuum oil-filter is communicated with the transformer body.
On vacuum unit and pipeline that oil conservator is communicated with, be provided with vacuum gauge, be used to observe the vacuum degree in the oil conservator, be provided with the moisture absorption pipeline at the oil conservator capsule.
Oil conservator is provided with the load switch oil conservator, and oil conservator is communicated with the loaded switch oil conservator by valve, and the loaded switch oil conservator is communicated with loaded switch on being arranged on the transformer body by pipeline.
Adopt above-mentioned transformer overall vacuum oiling device, concrete steps are as follows: the vacuum unit vacuumizes, and makes the interior vacuum degree of oil conservator reach standard-required, and keeps; Vacuum oil-filter oiling in the transformer body, 50 ℃ ± 5 ℃ of oil temperature, oil injecting speed is no more than 6000L/h, will vacuumize all the time in the oiling process; Vacuum oil-filter stopped oiling when the oil conservator oil level indicator was shown to the standard pasta; Close each valve, remove vacuum-pumping pipeline, make in the oil conservator to be communicated with atmosphere by respirator in the capsule, capsule still keeps negative pressure state outward.
The beneficial effects of the utility model are: adopt transformer overall vacuum oiling device and method, remain vacuum state in the transformer in the oiling process, avoided entering of air, guaranteed the quality of oiling.
