Abstract
The invention discloses a lightening proof transformer, and belongs to the transformer technical field; the transformer comprises a transformer housing; a high voltage end coil assembly and a low voltage end coil assembly are arranged in the transformer housing; each phase voltage line of the high voltage end coil assembly comprises a high voltage coil; each phase voltage line of the low voltage end coil assembly comprises a low voltage coil; the high voltage coil of each phase voltage line of the high voltage end coil assembly is connected in series with an induction coil. The lightening proof transformer has triple combined lightning proof protection measures, so very strong anti-lightening performance can be provided, thus ensuring the transformer not to be damaged by invasive lightning waves, and ensuring safety operation of the power distribution network.
Description
Technical field
The present invention relates to a kind of anti-lightning strike transformer, belong to transformer technology field.
Background technology
Transformer major part of the prior art does not arrange anti-thunder measure, even if transformer is provided with anti-thunder measure, the performance of its anti-thunder device is general all poor, can not play the effect of resisting lightning wave well.Because the anti-thunder device of transformer is weak, when lightning surge intrusion, the high-tension coil of transformer and low-voltage coil usually because immediate current, voltage are excessive, often can be damaged, even be caused power outage, or because of thunder and lightning initiation fire accident.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of anti-lightning strike transformer.
The present invention adopts technical scheme as follows:
A kind of anti-lightning strike transformer, comprises transformer casing, and described transformer casing internal is primarily of high-pressure side coil groups and low-pressure end coil groups composition; Each phase voltage circuit of described high-pressure side coil groups includes high-tension coil, each phase voltage circuit of described low-pressure end coil groups includes low-voltage coil, the high-tension coil on each phase voltage circuit of described high-pressure side coil groups is in series with inductance coil.
Screening arrangement is provided with between described high-pressure side coil groups and low-pressure end coil groups.
Compared with prior art, beneficial effect of the present invention is: the present invention has three recombination protection against lightning strikes measures, has extremely strong anti-lightning performance, can guarantee that transformer can not be broken by invaded lightning wave, thus ensure that the safe operation becoming power distribution network.
Accompanying drawing explanation
Figure 1 shows that structural representation of the present invention.
Embodiment
Embodiment:
Refer to shown in Fig. 1, a kind of anti-lightning strike transformer, comprises transformer casing 1, is provided with iron core 5 and is filled with transformer oil 7 in described transformer casing, and described transformer casing 1 inside is primarily of high-pressure side coil groups and low-pressure end coil groups composition; Each phase voltage circuit of described high-pressure side coil groups includes high-tension coil 3, each phase voltage circuit of described low-pressure end coil groups includes low-voltage coil 6, the high-tension coil on each phase voltage circuit of described high-pressure side coil groups is in series with inductance coil 2.
Screening arrangement 4 is provided with between described high-pressure side coil groups and low-pressure end coil groups.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
