AAnother contact and A mutually an end of a winding be connected, A mutually a winding the other end and C mutually an end of a winding be connected, the other end of a winding of C phase and C be fuse RD mutually
CA contact be connected C phase fuse RD
CAnother contact and C mutually the primary connection end be connected;
Above-mentioned B by leader cable and A mutually an end of a winding and C mutually an end of a winding link together simultaneously; So just constitute the V-V wiring construction of voltage transformer, and guarantee that a terminal communicates with a fuse.
Above-mentioned A, C be two primary connection ends mutually, and two insulated umbrella posts and pour mass constitute integral structure by cast.
An above-mentioned fuse is commercially available typing finished product.
Above-mentioned iron core adopts two C shape iron core butt joints to be hollow.
Principle of the present utility model and characteristics:
Operation principle of the present utility model is identical mutually with the operation principle of known voltage transformer, is characterized in:
The utility model has increased layer insulation thickness, and product anti overvoltage ability is strengthened.
Once adopt the V-type wiring, the once fuse protection of A, C facies tract, the primary connection end communicates with a fuse inside, and the outside splits, and it is quite convenient to change a fuse.
Adopt two C shape iron core butt joints of high-quality to be the alternative laminated core of port type iron core, the no-load loss and the no-load current of iron core are all little, improved the carrying load ability of product, also improved simultaneously operating efficiency, as long as first and second winding is installed in first and second skeleton, with on the coaxial stem stem that is enclosed within iron core of skeleton, get final product with steel band is fastening then again.
Increased the surface creepage distance of product, product has reached iv level gradation for surface pollution, safety, environmental protection, and operation is got up reliable and stable.
Adopt overall construction design, volume is little, and is in light weight, dwindled the occupation of land space, is easy to the installation of any direction.
Combination voltage instrument transformer of the present utility model is an overall structure; volume is little; easy for installation, have built-in fuse protection, avoided causing the damage of instrument transformer because of overvoltage and short circuit; and a built-in fuse is convenient to change; be easy to safeguard that combination voltage instrument transformer of the present utility model is excellent performance but also take up an area of for a short time not only, has immeasurable value to saving limited land resources; be renewal product of new generation, it is the key equipment that control and instrument show.
The utility model design science, reasonable, original, stable performance, reliable has extremely strong practicality and advance, and is easy for installation, simple to operate, operation cost is low, and suitable instrument transformer production industry and electric power maintenance are used.
