Abstract
The invention relates to a method for storing an ascending flanged base of a transformer and belongs to the technical field of transformers. The technical scheme is that dried pure nitrogen replaces transformer oil to be filled in the ascending flanged base of the transformer, so that the air pressure in the ascending flanged base of the transformer is larger than the external atmosphere pressure, the external moist air cannot enter the ascending flanged base of the transformer, and the effect of insulating and moisture prevention of a main body can be achieved. The method has the advantages that when the ascending flanged base is stored by the method, the transformer and an insulating member in the ascending flanged base of a product transported to the field are not affected with damp; and the method for storing the ascending flanged base of the transformer by filling nitrogen is easy and convenient to operate and less in cost compared with oil filling, reduces unnecessary waste and greatly reduces production cost of the transformer.
Description
Technical field
The present invention relates to a kind of method for the transformer lifting base preservation, belong to the transformer technology field.
Background technology
Large-scale power transformer often is subject to the restriction of transportation request at the oad of transportation, the seat that transformer need to be raise during transportation is pulled down.In the rising seat transformer fuse and insulating part are installed, make moist for preventing it, need fill with transformer oil and store again and transport.Product transport is to the erecting stage, because field condition restriction, the transformer oil that majority will raise in the seat bleeds off, and will raise to be installed on the transformer body again.Transformer oil in the rising seat can prevent that transformer and insulating part from making moist, thereby guarantees the voltage transformer safe operation.But the on-the-spot transformer oil that can't thoroughly reclaim has caused serious waste and environmental pollution, has greatly increased productive costs.
Summary of the invention
The purpose of this invention is to provide a kind of method of preserving for transformer lifting base, save time, laborsaving, save cost, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of method for the transformer lifting base preservation, pure nitrogen gas with drying replaces transformer oil to be filled in the transformer rising seat, guarantee that transformer raises an interior air pressure greater than external atmosphere pressure, extraneous wet gas just can not enter in the transformer rising seat, thereby play the effect of main body insulation and moisture, concrete steps are as follows:
1. will inflate stopper with the valve spanner and shrouding with holes fits together the shrouding that becomes gas nozzle, and the shrouding of gas nozzle will be installed in transformer raise on the deflation pipe flange on the seat;
2. desiccant is put into transformer rising seat, then sealing;
3. nitrogen gas cylinder is connected with the shrouding of gas nozzle by tire pressure gun, with the vent plug on the shrouding of tire pressure gun aligning gas nozzle, and firmly presses, and pulls the handle of tire pressure gun, is filled with nitrogen in transformer raises seat; During inflation, check a transformer rising seat internal pressure with compression indicator, be not more than 0.03Mpa;
4. after leaving standstill 24h, detect a transformer rising seat internal pressure, if less than 0.02MPa, check the gas leak point, and reseal, inflated with nitrogen until detect its internal pressure between 0.02MPa-0.03MPa, is put in storage again;
When the transformer after 5. putting in storage raises the seat delivery, check one by one one time, guarantee the inner malleation that keeps of transformer rising seat.
Described desiccant is moistureproof silica gel bag, puts into transformer rising seat; Further remove moisture in the transformer rising seat, to guarantee that the group parts do not make moist in the transformer lifting base.
Good effect of the present invention: by using this method storage transformer lifting base, be transported to the on-the-spot product phenomenon that transformer and insulating part make moist in the seat of all finding to raise; The transformer seat that raises fills the nitrogen store method, and is not only easy and simple to handle, and expense compares considerably lessly with oiling, reduced unnecessary waste, greatly reduces the productive costs of voltage transformer.
Description of drawings
Fig. 1 is the constructional drawing of the embodiment of the invention;
Among the figure: transformer rising seat 1, deflation pipe flange 2, tire pressure gun 3, nitrogen gas cylinder 4.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described by embodiment.
A kind of method for the transformer lifting base preservation, pure nitrogen gas with drying replaces transformer oil to be filled in the transformer rising seat, guarantee that transformer raises an interior air pressure greater than external atmosphere pressure, extraneous wet gas just can not enter in the transformer rising seat, thereby play the effect of main body insulation and moisture, concrete steps are as follows:
1. will inflate stopper with the valve spanner and shrouding with holes fits together the shrouding that becomes gas nozzle, and the shrouding of gas nozzle will be installed in transformer raise on the deflation pipe flange on the seat;
2. desiccant is put into transformer rising seat, then sealing;
3. nitrogen gas cylinder is connected with the shrouding of gas nozzle by tire pressure gun, with the vent plug on the shrouding of tire pressure gun aligning gas nozzle, and firmly presses, and pulls the handle of tire pressure gun, is filled with nitrogen in transformer raises seat; During inflation, check a transformer rising seat internal pressure with compression indicator, be not more than 0.03Mpa;
4. after leaving standstill 24h, detect a transformer rising seat internal pressure, if less than 0.02MPa, check the gas leak point, and reseal, inflated with nitrogen until detect its internal pressure between 0.02MPa-0.03MPa, is put in storage again;
When the transformer after 5. putting in storage raises the seat delivery, check one by one one time, guarantee the inner malleation that keeps of transformer rising seat.
