Description

A kind of high-power high voltage transformer
Technical field
A kind of high-power high voltage transformer is the utility model is related to, belongs to transformer technology field.
Background technology
Transformer is generally mounted to below 35KV power system, and the probability of short circuit accident occurs in 10~35kV power network It is much higher compared with more than 110kV power networks, the limiting short-circuit current when short trouble occurs for power system, to be cut-off with breaker Faulty line, and maintain substation busbars voltage to make All other routes in certain amplitude before breaker cut-offs faulty line Electrical equipment normal work.The cable of dry-type transformer is twisted by single line, has air gap between each cable, to protect Cable radiates when demonstrate,proving normal operation.Multi-cable is can contemplate when electric current is larger and around to reduce circulation, reducing damage Consumption, wire needs to replace, and low-voltage coil directly uses wire or copper foil coiling in the case where electric current is small, but when electric current is larger, with regard to nothing Method meets existing needs, it is impossible to is timely radiated, reduces the service life of transformer, substantially reduces making for product Use frequency.
Utility model content
In view of the above-mentioned problems, main purpose of the present utility model be to provide it is a kind of simple in construction, reasonable in design, easy to operate High-power high voltage transformer, the magnetic core of transformer is made full use of, coil is evenly distributed, and is advantageous to radiate, easily High-power is realized, compared with transformer of traditional coil on a stem, reduces distribution capacity.
The utility model is that solve above-mentioned technical problem by following technical proposals:A kind of high-power high voltage transformation Device, including the first magnetic core and the second magnetic core, first magnetic core and the second magnetic core are " rectangle " magnetic core, the first magnetic core and the second magnetic Core is adjacent and sets, wherein the side stem of the first magnetic core is provided with the first low-voltage coil and the first high-tension coil, the first low-voltage coil Inner, the first high-tension coil is outside;The adjacent stem of first magnetic core and the second magnetic core is provided with the second low-voltage coil and second High-tension coil, the second low-voltage coil is inner, and the second high-tension coil is outside;The side stem of second magnetic core is provided with the 3rd low pressure Coil and the 3rd high-tension coil, the 3rd low-voltage coil is inner, and the 3rd high-tension coil is outside;First low-voltage coil is low with the 3rd Connected after pressure coils from parallel connection of coils with the second low-voltage coil;After first high-tension coil is in parallel with the 3rd high-tension coil with the second high pressure Coil is connected.
Preferably, the first described magnetic core and the second magnetic core splice in length direction, two " rectangular shaped core " short columns with short column, Overall length is twice of single magnetic core after splicing, and width and thickness are constant.
Preferably, the magnetic core of the first described magnetic core and the second magnetic core is ferrite or non-crystaline amorphous metal or ultracrystalline magnetic core.
Positive effect of the present utility model is:The utility model is simple in construction, reasonable in design, to the magnetic of transformer Core is made full use of, and coil is evenly distributed, and is advantageous to radiate, is easily realized high-power, with traditional coil one Transformer on stem is compared, and reduces distribution capacity.
