Abstract
The invention relates to a resin-poured reel iron core transformer which is composed of an iron core, a high-voltage line package, a low-voltage line package, an upper end part clamp and a lower end part clamp, a high-voltage outgoing line insulator and a low-voltage outgoing line insulator. The iron core is a solid triangle or plane reel iron core, but no opening for installing the high-voltage line package and the low-voltage line package is arranged on the reel iron core. The high-voltage line package and the low-voltage line package on the same iron core column are solidified into one body by epoxy resin cure, or the high-voltage line package and the low-voltage line package on the same iron core column and the iron core are solidified into one body by epoxy resin cure, or the high-voltage line package and the low-voltage line package on each iron core column are solidified into one body by epoxy resin cure, or the high-voltage line package and the low-voltage line package on each iron core column and the iron core are solidified into one body by epoxy resin cure. The resin-poured reel iron core transformer has the advantages that as the reel iron core has no opening, the noload current and noise of the reel iron core are low; the high-voltage line package and the low-voltage line package are poured into one body by the epoxy resin cure, thereby enhancing the short circuit resisting and anti-shocking capacity of the transformer. As the high-voltage line package and the low-voltage line package are poured into one body, the processing difficulty and production cost are reduced.

Existing cast reel iron core transformer is in actual production process, generally be that iron core and line bag are separately produced, assembling then, that is: pre-processed open coil iron core, will good low pressure and the high-tension coil of cast, successively by the opening volume iron core of packing into, will roll up the butt joint of turning back of iron core opening again, because iron core has the opening loss, adopts the loss grade of the cast transformer of this open coil iron core can only accomplish S11.
Summary of the invention
The objective of the invention is to: there is above-mentioned defective in the transformer at existing non-packed dry type reel iron core transformer and open coil iron core cast, a kind of novel reel iron core transformer of resin-cast is proposed, transformer according to this invention production, it can overcome above-mentioned defective, the loss of transformer reduces, and performance is more reliable and more stable.
The present invention is achieved in that the reel iron core transformer of this resin-cast, form by iron core, high-voltage line bag, low-voltage line bag, upper and lower end parts folder, high-voltage terminal insulator and low pressure outlet insulator, it is characterized in that: iron core is the volume iron core, unwrap and establish opening on the volume iron core for high-voltage line bag and low-voltage line are installed, high-voltage line bag and low-voltage line are wrapped and are coated with epoxy resin, leave air flue between high-voltage line bag that twines on the same iron core column and the low-voltage line bag.
In the present invention: described iron core is three independently 3-D triangle volume iron cores of being combined to form of single frame volume iron core.
In the present invention: described iron core is the independently plane reeling iron core that is combined to form of single frame volume iron core of three or five.
In the present invention: high-voltage line bag on the same iron prop core and low-voltage line bag are one by the resin solidification of cast.
In the present invention: high-voltage line bag on the same iron core column and low-voltage line bag and iron core are one by the resin solidification of cast.
In the present invention: high-voltage line bag on each iron core column and low-voltage line bag are one by the resin solidification of cast.
In the present invention: high-voltage line bag on each iron core column and low-voltage line bag and iron core are one by the resin solidification of cast.
The invention has the advantages that: owing to adopt the volume iron core of remaining silent, the loss of iron core is little, and the no-load current of transformer is little, has reduced noise of transformer, has improved the operational efficiency of transformer; Because high and low line ball bag forms overall structure by resin-cast, has strengthened the Short Circuit withstand impulsive force of transformer; Adopt assembling die that low pressure and high-voltage line bag is integrated poured, reduced difficulty of processing and production cost.Transformer produced according to the invention, its loss grade has been accomplished S13, adopts high performance silicon steel sheet further to improve, and has promotional value.
