Abstract

A voltage transformer comprises an installation seat, a primary connection terminal, a secondary connection terminal, a primary coil winding a primary framework, a secondary coil winding a secondary framework and an iron core. The iron core is the stepless R-shaped iron core and is fixedly connected with the installation seat, and the primary coil winds the primary framework in a horizontally sectional mode. The secondary coil is sleeved on the iron core, the primary coil is sleeved on the periphery of the secondary coil in a hanging mode, and epoxy resins are filled between the primary coil and the secondary coil through casting in a pouring mode to form main insulation and an integral insulation resin casing with an integrated structure. The voltage transformer has the advantages that the brand-new stepless R-shaped iron core is adopted, and therefore, high magnetic permeability is achieved under the condition of the small section; the length of the horizontal section is enlarged, therefore, leakage flux is reduced, output capacity is improved, and the height dimension of the transformer is effectively reduced; the epoxy resins are poured into a whole so that partial discharge is nearly zero.

Description

A kind of voltage transformer
Technical field
The utility model relates to power transmission and transformation instrument transformer, particularly relates to a kind of voltage transformer.
Background technology
Deep development along with city rural power grids, transformer station, industrial and mining enterprises' automation, network, and the needs in a lot of frequent operations place, state's net DianKeYuan organization development the user demarcation type vacuum product of modern design of new generation, perfect performance, the FZW28-12F that safe and reliable, automaticity is high, the scope of application is wide, the voltage transformer of one of important accessory of this product, brand-new and higher requirement has been proposed, volume is little, output capacity is large, and partial discharge quantity is less than 5PC, according to this context request, succeeded in developing this type voltage transformer.
Utility model content
The technical problems to be solved in the utility model is, provides that a kind of volume is little, output capacity is large, and partial discharge quantity is less than the voltage transformer of 5PC.
The technical scheme adopting is:
A voltage transformer, comprises mounting seat, primary connection terminal, secondary wiring terminals, installs around primary winding on a skeleton, installs around secondary coil, iron core on the peripheral insulating board of iron core.Described iron core is stepless R iron-core, and iron core is fixedly connected with mounting seat, and described primary winding adopts transversal sectional to install around the primary winding on a skeleton.Described secondary coil is directly on the insulating board of stem periphery unshakable in one's determination, primary winding adopts lifting mode to be set in secondary coil periphery, adopt poured with epoxy resin to make potting resin between primary winding and secondary coil form main insulation, and the integral insulation resin enclosure of the structure that pours into an integrated entity again.
Above-mentioned transversal sectional installs around the primary winding on a skeleton, for having strengthened the primary winding of transversal sectional length.
The utility model has the advantages that:
1, adopt brand-new stepless R shaped iron core, under minimum cross section, realized high permeability.
2, strengthen transversal sectional length, reduced leakage flux, improved output capacity, and effectively dwindled the height dimension of instrument transformer.
3, between first and second, adopt hollow hoisting, poured with epoxy resin to be integrated, make partial discharge almost nil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Embodiment
A voltage transformer, comprises mounting seat 8, primary connection terminal 1, secondary wiring terminals 9, installs around primary winding 2 on a skeleton 3, installs around secondary coil 4, the secondary coil 4 on secondary skeleton 5, unshakable in one's determination 6 on the peripheral insulating board 5 of iron core.Described iron core 6 is stepless R iron-core, and unshakable in one's determination 6 are fixedly connected with mounting seat 8, and described primary winding 2 employings laterally divide two sections and install around on a skeleton 3, and for having strengthened the primary winding of transversal sectional length.Described secondary coil 4 is directly wound on the insulating board 5 of 6 peripheries unshakable in one's determination, primary winding 2 adopts lifting mode to be set in secondary coil 4 peripheries, adopt poured with epoxy resin to make primary winding 2 and 4 potting resins of secondary coil form main insulation, and the integral insulation resin enclosure 7 of the structure that pours into an integrated entity again, forms a kind of voltage transformer.
