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.
The utility model content
The purpose of this utility model is: 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 utility model production, it can overcome above-mentioned defective, the loss of transformer reduces, and performance is more reliable and more stable.
The utility model 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 utility model: 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 utility model: 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 utility model: 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 utility model: 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 utility model: high-voltage line bag on each iron core column and low-voltage line bag are one by the resin solidification of cast.
In the utility model: 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.
Advantage of the present utility model is: 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.According to the transformer that the utility model is produced, its loss grade has been accomplished S13, adopts high performance silicon steel sheet further to improve, and has promotional value.
