The anti-resonance-oscillation high-voltage mutual inductor iron core comprises a silicon sheet laminated iron core, an iron core support bracket, an epoxy glass adhesive tape and an adjusting clamp device. The external part of the silicon sheet laminated iron core is sheathed with the iron core support bracket, and an insulating paper board is arranged between the silicon sheet laminated iron core and the iron core support bracket. The epoxy glass adhesive tape is circled outside silicon sheets and the iron core support bracket, and both ends of the epoxy glass adhesive tape are fixed on the adjusting clamp device. The anti-resonance-oscillation high-voltage mutual inductor iron core has the advantages that the silicon sheets are not perforated in the silicon sheet process, the silicon sheets are seamed in a right angle mode, the anti-resonance-oscillation high-voltage mutual inductor iron core has convenient mount, consistent production quality, high performance, stable quality, small size and low product no-load loss, reduces the processing procedure of the iron core, reduces the fault points, and improves the anti-resonance-oscillation ability of the products, and the relation curve of the exciting current and the voltage is approximate to linear relation.
Description
Technical field
This utility model relates to a kind of high voltage potential transformer, and specifically a kind of rated voltage that is applicable to is the antiresonance high voltage potential transformer iron core of 110kV and above electrical network.
Background technology
Existing high voltage potential transformer iron core adopts length, the width processing in accordance with regulations of the following silicon steel sheet (30HZ-145) of 0.35mm more, in the two ends punching, carry out closed assembly and be shaped to iron core, on four jiaos of iron cores, pass iron core with the punching screw rod, screw rod middle part is with the insulation paper tube with width such as iron core, prevent that screw rod from directly contacting with iron core, the screw rod two ends are fastening with insulation spacer, double nut, thereby reach fastening iron core effect.
After the shortcoming of this fastening iron core is the iron core punching, easily produce eddy current loss, and in punching screw rod when assembling, easily and the iron core short circuit, increase eddy current loss, increase no-load error, the stability of properties of product, excitation property and antiresonance ability variation influence the piece electrical performance of high voltage potential transformer product.
Summary of the invention
This utility model is to be solved to be exactly after punching on the existing iron core, easy and iron core short circuit during the assembling of easily generation eddy current loss, and punching screw rod increases eddy current loss, increase no-load error, influence the problem of high voltage potential transformer product piece electrical performance.Provide a kind of difficult generation eddy current consume, stable performance, the antiresonance high voltage potential transformer iron core that excitation property is good, the antiresonance ability is strong.
Solve the technical scheme that its technical problem adopts: a kind of antiresonance high voltage potential transformer iron core, comprise the silicon steel sheet laminated core, it is characterized in that: this transformer iron core is made up of silicon steel sheet laminated core, iron core support, expoxy glass adhesive tape, adjusting fastener, silicon steel sheet laminated core outer cover is connected to the iron core support, between silicon steel sheet laminated core and iron core support, place insulating board, silicon steel sheet and iron core support are surrounded with the expoxy glass adhesive tape outward, and the two ends of expoxy glass adhesive tape are fixed on to be regulated on the fastener.
Described iron core support is that two angle bar are spliced into " ㄩ " shape, and mounting hole is arranged on angle bar, and the expoxy glass adhesive tape passes mounting hole and is looped around on silicon steel sheet laminated core and the iron core support.
Described adjusting fastener is made up of fastening block, tightening bolt, and fastening block is two, and the interlude of fastening block is cylindrical, two ends are square, there is through hole at two ends at fastening block, and tightening bolt passes the through hole at two fastening block two ends, are connected with nut in the end of tightening bolt.
Beneficial effect: the utility model is compared with existing iron core colligation technology, has the following advantages: 1. because silicon steel sheet is processed into the rectangle of rule, and do not punch, it during core lamination stack the right angle seam, closed assembly is convenient, the little good manufacturability of seam, product quality unanimity, performance height; 2. because of silicon steel sheet does not need to carry out punching processing, reduce the iron core manufacturing procedure, reduced the fault point, steady quality; 3. than product with the equal parameter request of electric pressure, it is little to have volume, product no-load loss is low, compare similar same parameter product no-load loss as the 110kV product and reduce 30-40W, the product excitation property is good, between rated voltage 20%-150% measurement point, exciting current, voltage curve are similar to linear, for example the exciting current under 150% times of voltage of 110kV product be under 100% voltage exciting current 3.04-3.56 doubly, like product is 7-10 times, and this characteristic has improved the antiresonance ability of product greatly.
