Abstract
The utility model relates to an outdoor voltage transformer, which comprises an iron core, a primary coil, a secondary coil, a first fuse and a second fuse. The primary coil is wound on a primary skeleton, and the secondary coil is wound on a secondary skeleton; the primary coil serves as an outer layer, the secondary coil servers as an inner layer, and the primary coil and the secondary coil are coaxially arranged on the C-shaped iron core; and the primary coil, the secondary coil and the iron core are made into an integrated structure through epoxy resin casting, and an epoxy resin cast body and an outer die-cast silicone rubber form a shell. The utility model has the advantages of scientific, reasonable and creative design, stable performance, reliable running, stronger practicality and advancement, convenient installation, simple operation and low operating cost.
Description
Technical field
The utility model relates to a kind of instrument transformer, specifically is a kind of outdoor voltage transformer, and trade name is the outdoor voltage transformer of JDZ15-10RW.
Background technology
In the running of electrical network,, the outdoor vacuum fuse substantially all is installed at every branched line in order to guarantee that every branched line when breaking down, does not influence the safe power supply of main line.Old-fashioned outdoor vacuum fuse, the close/open machine complexity, energy storage motor needs the capacity of 1000VA, and this just requires, and voltage transformer volume to energy storage motor power supply is big, Heavy Weight, cost height, and fuse is external, installs complicated.But along with vacuum circuit-breaker develops towards intelligent, miniaturization, more and more its development of incompatibility of supporting with it voltage transformer, at this situation, we have developed this voltage transformer.
The utility model content
The purpose of this utility model provides that a kind of volume is little, in light weight, the outdoor voltage transformer of good insulation preformance.
The technical scheme that adopts is:
A kind of outdoor voltage transformer comprises C sections core, primary winding, secondary coil, two terminals and two fuses.
The primary winding winding is on skeleton.The secondary coil winding is on secondary skeleton, and primary winding is outer, and secondary coil is an internal layer, coaxial being installed on the C sections core.The top of primary winding and end are welded with copper sheathing respectively, stud with spring in the copper sheathing, and the lower end of two fuses withstands on respectively finishes on the spring and being connected of Inside coil.The leading-out terminal of secondary coil is connected with corresponding wiring terminal in the secondary terminal board respectively.Primary winding, secondary coil and iron core are by poured with epoxy resin structure in aggregates, and this epoxy resin poured body and outermost die casting silicon rubber are housing.Two fuses are arranged in the compound insulation sleeve of epoxy resin and silicon rubber, and the upper end of two fuses connects with a corresponding terminal respectively.
Advantage of the present utility model is:
Falope epoxy resins compound inslation is adopted in insulation, and its major advantage is that silicon rubber has good migration of hydrophobicity, and outdoor resin does not possess, and silicon rubber uvioresistant, anti-aging, anti-electric leakage corrosion, and performance all is better than outdoor resin.We adopt advanced optimization technology, the outdoor resin of inner employing, and silicon rubber one-shot forming sulfurization technology is adopted in the outside, not only effectively improved the outdoor adaptability of instrument transformer, and cost reduces greatly.
Adopt the fuse in-laid process, traditional outdoor drop-out type fuse is changed into the built-in fuse of miniaturization insulation resin of excellent performance, be built in the inside of two insulating cases of instrument transformer, effectively reduced mounting complexity, this instrument transformer can be installed by any direction.
Optimizing internal process, adopt advanced C sections core, effectively reduce core loss and no-load current, is that the instrument transformer volume significantly dwindles, and weight ratio traditional type voltage transformer alleviates 2/5.
The utility model design science, reasonable, original, stable performance, reliable, easy for installation, simple to operate, operation cost is low.
