Abstract
The utility model relates to a transformer with a novel outgoing mode, which comprise an iron core, wherein the iron core is provided with a winding base, the winding base is respectively wound with a low-voltage coil and a high-voltage coil, the outside of the high-voltage coil is also provided with a voltage regulation coil, and two connecting lugs are extracted from the high-voltage coil to be connected with two connecting lugs of the voltage regulation coil; the connecting part of the high-voltage coil and the voltage regulation coil is connected with a tapping switch; the two connecting lugs of the high-voltage coil are positioned on the middle part of the high-voltage coil; the high-voltage coil and the voltage regulation coil adopt copper wires; the connecting lug is wrapped with turn insulation; and the turn insulation consists of high-density paper and crepe paper. The transformer has improved short-circuit resistant capacity, and more compact structure and also can save energy and lower energy consumption.
Description
Technical field
The utility model relates to a kind of transformer, especially relates to a kind of transformer of high pressure delta connection.
Background technology
In electric power was carried, transformer was absolutely necessary.And present transformer all is by casing, iron core, and coil, lead-out terminal constitutes, because structural problem, volume is big, the cost height, security reliability is poor.Particularly in-fighting is big, and energy waste is big, has restricted the production of transformer and effectively uses, and particularly in energy-intensive today, this energy consumption is big, and its improvement of transformer that cost is high is determined to win.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of compact conformation and can reduce that short circuit takes place has the novel line outgoing mode transformer.
The technical scheme in the invention for solving the technical problem is: a kind of transformer with novel line outgoing mode, comprise iron core, iron core is provided with winding base, twine low-voltage coil and high-tension coil on the winding base respectively, also be provided with voltage regulation coil in high-tension coil outside, on described high-tension coil, extract two wiring out and lift one's head to lift one's head and be connected with two wiring of voltage regulation coil.
For better control transformer, be connected to shunting switch in the junction of high-tension coil and voltage regulation coil.
In order better to reach required effect, through repeatedly experiment, two joints on the described high-tension coil are positioned at the high-tension coil middle part.
Described high-tension coil and voltage regulation coil all adopt copper cash, can better conduct electricity.
In order to prevent short circuit, described wiring lifts one's head to wrap up turn insulation; Described turn insulation is made up of high-density paper and crimped paper.
The beneficial effects of the utility model are: by adopting above-mentioned mode, the anti-short circuit capability of transformer strengthens, and structure is compact more, and can save energy and reduce the cost.

Embodiment
A kind of as shown in Figure 1 transformer with novel line outgoing mode, comprise iron core, iron core is provided with winding base, twine low-voltage coil and high-tension coil 1 on the winding base respectively, also be provided with voltage regulation coil 2 in high-tension coil 1 outside, extracting two wiring on described high-tension coil 1 out lifts one's head, fix through colligation, be embedded in earlier on two line segments, on voltage regulation coil position corresponding, reserve perforate again with it, voltage regulation coil cover is drawn two connector lugs after outside again, be connected lifting one's head to lift one's head with two wiring of voltage regulation coil 2 after wrapping turn insulation on the line; Junction at high-tension coil and voltage regulation coil 2 is connected to shunting switch; Two joints on the described high-tension coil are positioned at the high-tension coil middle part; Described high-tension coil and voltage regulation coil 2 all adopt copper cash; Described wiring lifts one's head to wrap up turn insulation; Described turn insulation is made up of high-density paper and crimped paper.
The 35KV transformer that high pressure is delta connection, extract two wiring out at the high-tension coil middle part, fix through colligation, be embedded in earlier on two line segments, on voltage regulation coil 2 positions corresponding, reserve perforate again with it, again two connector lugs are drawn after overlapping voltage regulation coil 2 outside, lift one's head wrap turn insulation on the line after with voltage regulation coil 2 on lift one's head and connect mutually, and it is fixing, be connected on the shunting switch after wrapping insulating material, shunting switch and fuel tank are fixed, and the insulation distance between high pressure and the voltage regulation coil 2 can be reduced to 12mm, and old structure needs 20～24mm.Process experiment showed, that the mode of connection of this high pressure middle part outlet than other delta connection circuit economy, can reduce the insulation level of pressure regulation winding and on load tap changer, reduces insulation distance.Make its more compact structure, the production tool that reduces cost is had certain effect.
