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

Three-phase combined voltage transformers of the 35KV with fuse
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.
Utility model content
Problem to be solved in the utility model is to propose a kind of 35KV with the three phase combined of fuse for problem above Voltage transformer.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is:35KV is three combined with fuse Formula voltage transformer, including iron core, line winding, secondary line winding, fuse, the secondary line winding and a line winding It is wound on iron core, a line winding is connected by a connection inserting part with fuse, and iron core is poured with first and second line winding Note is internal in cast.
Further, the primary line winding overhang is provided with a line terminals and is used to draw terminal block.
Further, the iron core and a line winding and Secondary Winding are formed together with the poured with epoxy resin of high-quality.
Further, insulated sleeve is provided with a line terminals, changeable type is installed in the insulated sleeve and is melted Disconnected device.
Further, extension type contact arm is installed on the insulated sleeve.
Further, anti-electricity-theft protective cover is installed outside the secondary line winding.
Further, the transformer bottom is by having filled base.
This utility model is had the advantage that with beneficial effect:This novel voltage mutual inductor iron core adopts high-quality cold rolled silicon steel Piece, forms through winding annealing, and iron loss is little, magnetic is close low, and product data are good, stable performance.Iron core and first winding and it is secondary around Group is formed together with the poured with epoxy resin of high-quality, and is provided with changeable type fuse in a terminal insulative sleeve pipe, because molten Disconnected device is the built-in area for reducing whole cabinet;Because being Integral three-phase, so this transformer may replace 35KV two The transformer that group is used, can be widely used in any switch cubicle with PT cars in.
