Description
Technical field
The present invention relates to field of electrical equipment, in particular it relates to a kind of 10kV oil-filled transformer manufacture method.
Background technology
At present, the scheduled overhaul system that in power system, power equipment uses mostly also exists major defect, as provisional
Maintenance is frequently, maintenance is not enough or maintenance is superfluous, blindly maintenance etc., this make countries in the world every year in terms of maintenance of equipment cost huge
Greatly.And for a long time, China's power system performs periodic inspection system to power equipment, the most planned time cycle is to setting
, thus there is maintenance and excessively and overhaul not enough drawback in standby detection and maintenance.Because of fault at power train unification, often cause
Large-area power failure.And there is the problem that fault rate is higher in existing power equipment.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose a kind of 10kV oil-filled transformer manufacture method, to realize
The advantage reducing equipment failure rate.
For achieving the above object, the technical solution used in the present invention is:
A kind of 10kV oil-filled transformer manufacture method, including, cold rolled grain grain-oriented Si steel sheet will be used to make non-crystaline amorphous metal material
The iron core overlap joint end face solid seal glue of material seals, and by the iron yoke part unshakable in one's determination closed and two core limb paper usings not overlapping winding
Groove and contraction band tighten；
Using enamel-cover copper conductor coiling high pressure winding, it is anti-that the coil interlayer of high pressure winding uses diamond dotted insulating paper to carry out insulation
Protect；
Low pressure winding is formed by whole Copper Foil coiling, and the coil interlayer of low pressure winding uses double-deck diamond dotted insulating paper to carry out absolutely
Edge protects,
Respectively by high pressure winding, low pressure winding together with iron core combination；
Then the high pressure winding combined, low pressure winding and iron core are put in fuel tank；
Use vacuum oil technique injection transformer oil in fuel tank.
Preferably, described fuel tank is: tubular type tank or corrugated tank.
Preferably, use vacuum oil technique during injection transformer oil in fuel tank, it should be ensured that in transformer body and coil
Insulant is infiltrated by transformer oil completely.
Technical scheme has the advantages that
Technical scheme, by the improvement to transformator processing technology, thus reduces the purpose of equipment failure rate.
Detailed description of the invention
A kind of 10kV oil-filled transformer manufacture method, including, cold rolled grain grain-oriented Si steel sheet will be used to make amorphous and to close
The iron core overlap joint end face solid seal glue of gold copper-base alloy seals, and by the iron yoke part unshakable in one's determination closed and two core limbs not overlapping winding
Paper using groove and contraction band tighten；
Using enamel-cover copper conductor coiling high pressure winding, it is anti-that the coil interlayer of high pressure winding uses diamond dotted insulating paper to carry out insulation
Protect；
Low pressure winding is formed by whole Copper Foil coiling, and the coil interlayer of low pressure winding uses double-deck diamond dotted insulating paper to carry out absolutely
Edge protects,
Respectively by high pressure winding, low pressure winding together with iron core combination；
Then the high pressure winding combined, low pressure winding and iron core are put in fuel tank；
Use vacuum oil technique injection transformer oil in fuel tank.
Preferably, described fuel tank is: tubular type tank or corrugated tank.
Preferably, use vacuum oil technique during injection transformer oil in fuel tank, it should be ensured that in transformer body and coil
Insulant is infiltrated by transformer oil completely.
Transformer oil should be the mineral oil of standard, and oil flash is not less than 140 ° of C, in addition to antioxidant, must not add any
Additive.Its physical parameter is as follows:
(1) breakdown voltage: >=35kV
(2) dielectric dissipation factor tan δ (90 DEG C) :≤1.0%.
Measurement device of oil tempera: transformator should have the base for glass-stem thermometer.Base should be located at the top of fuel tank, and stretches
Enter 120mm ± 10mm in oil.
The installation site of signal thermometer should be easy to observe.
Chiller: the quantity of radiator and cooling capacity should be able to disperse heat produced by total losses.
Paint and antirust requirement: oil tank of transformer is inside and outside and adnexa is in addition to non-ferrous metal and zinc-plated ironware, all metalworks
All should eliminate rust and spray paint, paint has from antifouling capacity, and takes measures to prevent enamelled coating in transport and lifting from peeling off with rotten.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
