Description

Comprehensive testing device for transformer

Technical field

The utility model relates to transformer detection equipment technical field, is specifically related to a kind of comprehensive testing device for transformer.

Background technology

Transformer has the function of voltage, electric current or impedance transformation, is widely used in distribution system and various electrical equipment produces Product.Which is the schematic diagram of existing device for transformer.This transformer is the principle utilizing electric energy and magnetic energy transformation induction, by the beginning of one Level side coiling and two groups of coils of a primary side coiling curl up respectively on common iron core, by primary side winding and primary side around The ratio of the curled up number of turn of line adjusts voltage and the electric current of input/output.In theory, the primary side winding of transformer and secondary When the ratio of the curled up number of turn of side coiling is correct, necessarily can adjust correct input/output voltage and electric current to scale, But, transformer often because the error of technique, causes its primary side winding and the curled up number of turn of primary side coiling during fabrication Ratio incorrect, and correct input/output voltage and electric current cannot be adjusted to scale, therefore transformer is produced After Laiing, need to first pass through can dispatch from the factory after non-defective unit is confirmed as in detection sells use.

Current 80kV current conversion station is positioned at remote village, Over-size transport inclement condition, and measure cost is high, and a lot of measure is Temperature pier measure, after engineering puts into operation, if converter power transformer breaks down needs Disintegration overhaul, now returns factory and will there is big part The uncertainty and risks such as transport difficult and expense height.The on-the-spot factory building of converter power transformer temporarily building 80kV is expensive and time-consuming, And building equipment needed for factory building to should be noted that and transport, quantities is big, and factory building needs periodic maintenance after building up, just for this transformation Device cost of investment is huge.Before this engineering, ± 50kV current conversion station and ± 50kV current conversion station are once after engineering puts into operation, and scene is taken Building ad hoc inspection and repair factory building, the crane gear joining winding of can slinging realizes that the fault change of current becomes Disintegration overhaul, and after maintenance, equipment uses heat Device body is dried by oil spraying method.But do not possess indoor experimental condition due to factory building, the converter power transformer after maintenance has only done can The pilot project operating out of doors, does not carry out and requires the higher pilot project needing indoors to carry out to environmental condition.At this The wide extra-high voltage project of cloud ± 80kV Chuxiong current conversion station before engineering once had 2 high-end converter power transformers little individually because of shielding line Loosened screw defect, on-the-spot without maintenance factory building and experiment hall, do not possess the indoor experimental condition after maintenance and maintenance, be forced Return factory and office's reason, return the costly and time consuming length of factory's not only freight.And the converter power transformer fault rate after the operation several years is higher, if needing Disintegration overhaul and test, return factory and office's reason and will pay bigger cost and risk.In conventional engineering, ± 50kV Xingren current conversion station and ± 50kV natural bridge current conversion station once scene is built interim easy surviving factory building and is realized that the change of current becomes maintenance, but for ± 80kV change of current change Depressor product, owing to small product size is big, Heavy Weight, compact conformation are complicated, if carrying out Disintegration overhaul work at the scene, need to be furnished with The maintenance factory building of device body heavy lifting equipment；Meanwhile, ± 80kV converter power transformer product voltage insulation higher grade is, after maintenance Product gas phase drying equipment should be used to be dried device body, and carry out comprehensive shop test project (include indoor test item Mesh), whether to examine properties of product qualified, the disappearance of pilot project will leave major quality hidden danger and risk to equipment.

The utility model of Application No. 201210184052.X discloses a kind of Repair of Transformer platform, and it includes connecting the end Seat, grid pedal and stepped fastener, wherein, described grid pedal is made up of two pieces of transverse slats and polylith riser, at the bottom of described connection Seat includes fixed plate and connecting bottom board, and described fixed plate is provided with installing hole, and plate face four limit of described connecting bottom board is fixed respectively Being connected with fixed plate, the plate face middle opening of described connecting bottom board, described opening part is provided with fixed dam, described grid pedal Connected by the plurality of described stepped fastener and the described fixed dam being connected on base are fixing.This utility model can not be given Maintenance provides a good environment, and cannot arrange fixing for small part during maintenance, and scene is more mixed and disorderly.

The utility model of Application No. 201520153296.0 discloses between a kind of Power Transformer in Field maintenance, including outside Peripheral frame frame and the ceiling being removably attached to peripheral frame top, described peripheral frame encloses maintenance district, described inspection Repair district and include transformer used area, platform area and the equipment installing zone for installation and repairing equipment；Described peripheral frame and ceiling All using metal rod to be removably formed by connecting, described peripheral frame is provided with the hydrophobicity cloth of light-permeable, described Ceiling is provided with the hydrophobicity paulin top cloth of light-permeable；Maintenance is provided with temperature sensor and humidity sensor in district；Repair apparatus bag Include for transformer insulation oil is detected vacuum oil-filter, for carrying out vacuumizing the vacuum of process to transformer air chamber Pump and for transformer part withering drying box；The utility model is easily installed dismounting, Rainproof moisture-proof, simultaneously Ensure light transmission, it is achieved polytype test operation, meet wanting of timing maintenance, repair based on condition of component and provisional trouble hunting Ask.But this utility model construction cost is high, builds a factory building cost well imagine for a transformer, and cannot create Make environment, use limitation bigger；And during the broiling summer, sunshine ratio is stronger, solar radiation can make spin manifold temperature too high, The accuracy of impact detection, what is more important side storehouse is very high, easily touches electric wire, easily gets an electric shock, and uses dangerous.

And, current prior art is when transformer Disintegration overhaul, and the parts especially iron core etc. under dismounting is longer Parts reasonably do not put place, are often placed in ground, not convenient, inefficiency when cleaning polishing.Additionally, screw, nut and The widgets such as pad are usually lost, are damaged.Transformer Disintegration overhaul works, be a kind of to standard operation exigent electric power make Industry, nonstandard putting easily causes working site confusion, creates potential safety hazard, also cause strong influence to service work.
