Abstract
The invention relates to a cylindrical dry type high-voltage capacitor core, belonging to the field of high-voltage capacitors. The cylindrical dry type high-voltage capacitor core is prepared by using a method comprising the following steps of: using an insulation film and adhesives coatings (6) to prepare a composite insulation film of which two sides are printed with the adhesives coatings (6) processed into a semi-solidified state; and then performing capacitor core winding to obtain wound elements of which the quantity and the size are specified in the design; after the winding is finished, performing temperature rising treatment so that the semi-solidified adhesives coatings are completely cured and the whole cylindrical dry type high-voltage capacitor core becomes a firm whole, thereby solving the problem that the cylindrical dry type high-voltage capacitor core which is installed vertically droops and deforms because of gravity during operation. The cylindrical dry type high-voltage capacitor core provided by the invention can be used as a capacitive divider and does not deform when installed vertically, and can improve long-terming safe operational performance of a gas insulated dry type capacitor voltage transformer or coupling capacitor.
Description
Technical field
The invention belongs to the High-Voltage Electrical Appliances field, relate to a kind of novel compound with insulation film and curable adhesive be the cylinder dry-type high-voltage capacitor body of dielectric, can be used as the capacitor body of making capacitor voltage divider in gas isolated dry type capacitance type potential transformer or the coupling condenser uses, being applied to rated voltage is that rated frequency was in the electric power system of 50Hz or 60Hz more than 110kV reached.
Background technology
At present, the cylinder dry-type high-voltage capacitor body of existing application gas isolated dry type capacitance type potential transformer or coupling condenser in the open air, be that the dielectric of capacity cell is that insulating gas and insulation film are compound by all series connection and be wound into the concentric cylinder body structure by metal forming and insulation film on the metal mandrel of a plurality of capacity cells.It is vertically to install that cylinder dry-type high-voltage capacitor body is in operation, and because the deadweight effect of capacitor body, between the insulation film and and aluminium foil between the simple shape that keeps product by the frictional force between them, and no matter the tension force of coiling is big again, cylinder dry-type high-voltage capacitor body also has gravity sag in various degree inevitably and the phenomenon of deformation takes place, cause between insulation film and the insulation film or relative moving taken place between insulation film and the metal forming, light then influence the dielectric loss of product, heavy then the change that produces partial discharge or capacitance, thereby cause the reduction of certainty of measurement and then overproof, finally cause the consequence of product failure.
Summary of the invention
The objective of the invention is to overcome cylinder dry-type high-voltage capacitor body the defective of generation because of the sagging distortion of gravity vertically is installed when operation, provide a kind of under the situation of vertically installing, the cylinder dry-type high-voltage capacitor body that the capacitor voltage divider of making gas isolated dry type capacitance type potential transformer or coupling condenser that does not deform is used can improve gas isolated dry type capacitance type potential transformer or coupling condenser long-term safety runnability.
The present invention is a kind of cylinder dry-type high-voltage capacitor body, by one deck compound inslation film (3) at least as the dielectric of capacity cell, constitute a capacity cell by two metal formings (4) as capacitor plate, and be wound into cylindrical structure, and be integral through heating cure by the series connection of a plurality of capacity cells.By after the two-sided process roughening treatment of insulation film (5), approach and the uniform thick good thixotropic adhesive coating (6) that has at the two-face printing last layer respectively, this adhesive is the same with thermosetting compound material that contains latency promoter, handling at a certain temperature cannot not become stickingly adhesive and soft semi-cured state, and handle at a certain temperature and can continue to react to full solidification, and the insulation film of adhesive and alligatoring and metal forming have good adhesion and bonding force.Adopt the compound inslation film (3) of printed on both sides adhesive coating (6) to carry out the capacitor body coiling then, turn to the parts number and the size of designing requirement, the processing of heating after coiling is finished, make the adhesive coating full solidification of semi-cured state, between compound inslation film (3) and the capacitor mandrel (1), all be bonded into one between the compound inslation film (3) of each layer and between compound inslation film (3) and the metal forming (4), cylinder dry-type high-voltage capacitor body after the curing becomes a firm integral body, thereby solved cylinder dry-type high-voltage capacitor body the problem of generation because of the sagging distortion of gravity is installed vertically when operation.
