Description
Technical field
The utility model relates to voltage transformer, particularly relates to a kind of voltage transformer of outdoor small-sized band fuse compound inslation.
Background technology
In the running of electrical network, in order to ensure that every bar branched line is when breaking down, and does not affect the safe power supply of main line, at every bar branched line, outdoor vacuum fuse is substantially all installed.Old-fashioned outdoor vacuum fuse, close/open machine is complicated, and energy storage motor needs the capacity of 1000VA, and this just requires that the voltage transformer volume of powering to energy storage motor is large, Heavy Weight, cost are high, and fuse is external, installs complicated.But along with vacuum circuit-breaker is towards intelligent, miniaturization development, voltage transformer supporting with it is more and more not suitable with its development.
Utility model content
The purpose of this utility model is for the voltage transformer volume used at present is large, Heavy Weight, cost are high, install complicated deficiency, provides a kind of small outdoor voltage transformer.
The technical scheme adopted is:
A kind of small outdoor voltage transformer, comprise primary connection terminal, once go between copper strips, primary winding supporting bracket, around the primary winding on a skeleton, around the secondary coil on secondary skeleton, secondary connection inserts, iron core, fuse, Compress Spring and silicone rubber insulation layer.Described fuse is contained in primary connection terminal, fuse one end is provided with screwed pipe, be threaded on a terminal cap by screwed pipe, the fuse other end is contained in the fuse light cap with Compress Spring, fuse light cap, once lead-in wire copper strips become a suspension bracket with primary winding supporting bracket assembly welding, Compress Spring connects the copper strips that once goes between, and its Compress Spring connects fuse.Primary winding is installed on iron core, and secondary coil installs around on primary winding, adopts main insulation resin filling between secondary coil and primary winding, and secondary coil is by lead-in wire connecting secondary wiring inserts.Primary connection connecting terminals adopts poured with epoxy resin resin insulating barrier with instrument transformer, the outer composite silicone rubber insulating barrier of resin insulating barrier.
Above-mentioned iron core adopts R shaped iron core.
The utility model is compared with existing outdoor mutual inductor:
1, the utility model adopts advanced Optimization Technology, the outdoor resin of inner employing, the one-time formed silicone rubber insulation layer of outside employing, silicon rubber has excellent migration of hydrophobicity, and traditional outdoor resin does not possess, and silicon rubber uvioresistant, anti-aging, tracking-resistant corrosion, not only effectively improve the outdoor adaptability of instrument transformer, and cost reduces greatly.
2, adopt fuse in-laid process, traditional outdoor drop-out fuse is changed into the miniaturized insulation resin fuse of excellent performance, be built in two terminal inner of instrument transformer, effectively reduce mounting complexity, instrument transformer can be installed by any direction.
3, optimize internal process, adopt advanced R shaped iron core, effectively reduce core loss and no-load current, be that instrument transformer volume significantly reduces, weight ratio traditional type voltage transformer alleviates 2/5.
The utility model design science, rationally, stable performance, reliable, easy for installation, simple to operate, operation cost is low, practical.
