This novel voltage transformer iron core adopts high -quality cold -rolled silicon steel sheets, and it forms to anneal through convoluteing, and the iron loss is little, magnetism is close low, and product data are good, the stable performance. Iron core and primary winding and secondary winding form with the epoxy resin casting of high grade together, and install removable formula fuse in a terminal insulation support, have reduced whole cabinet area physically because of the fuse is built -in, because of being the three -phase integral type, so the mutual -inductor of two a set of uses of this mutual -inductor substituted 35KV can extensively be arranged in in any cubical switchboard and the PT car.
Description
Technical field
This utility model is related to voltage transformer technical field, and three more particularly, to a kind of 35KV with fuse are combined
Formula voltage transformer.
Background technology
The purpose of voltage transformer voltage of transformation, is primarily used to be powered to measuring instrumentss and protective relaying device, is used for
The voltage of measurement circuitry, power and electric energy, or for the expensive equipment in the protection circuit in line failure, motor and
Transformator, therefore the capacity very little of voltage transformer, it is typically all only several volt-amperes, tens volt-amperes, maximum to be also less than one kilovolt
Peace.
General, voltage transformer is the transformator of a ribbon core.It mainly by first and second line winding circle, iron core and
Insulation composition.When a voltage U1 is applied in first winding, a magnetic flux φ is just produced in the core, according to electromagnetic induction
Law, then just produce a secondary voltage U2 in Secondary Winding.Change once or Secondary Winding the number of turn, difference can be produced
Primary voltage and secondary voltage ratio, this can constitute voltage transformer not on year-on-year basis.Voltage transformer by high voltage in proportion
Low-voltage, i.e. 100V are converted into, voltage transformer primary side is connected on primary system, secondary side joint measuring instrumentss, relay protection etc..
Conventional voltage transformer, is all that fuse is installed outside transformer, is held due to the external time length of fuse
Easily aging, being in configuration can be because model is mismatched affects quality of transformer performance.Therefore study a kind of three combined with fuse
Formula voltage transformer, is very important for this area.
