The beneficial effects of the utility model are: adopted a kind of brand-new structural design, realized and on the basis of zigzag connection, adopted Split type low-voltage coil structure, realized a kind of high voltage, the two low pressure zigzag connection power transformers of large capacity.
Brief description of the drawings
Fig. 1 is the elementary diagram of the utility model low pressure winding;
Fig. 2 is structure chart of the present utility model;
In figure: device body 1, device body 22, fuel tank 3, low pressure winding 1, low pressure winding 25, high pressure winding 6, iron core 7, switch 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of two low pressure zigzag connection transformer, comprise device body 1, device body 22, fuel tank 3 and switch 8, described device body 1, device body 22 are arranged in parallel in fuel tank 3 before and after transformer short-axis direction, the loop construction of device body 1, device body 22 is identical, three compatible amount are the half of rated capacity, be respectively equipped with low pressure winding 1, low pressure winding 25, high pressure winding 6 and iron core 7, be arranged in order, the high pressure winding 6 of the two is in parallel mutually, the three-phase of low pressure winding 1, low pressure winding 25 is zigzag connection, independently draws respectively.
The capacity of described low pressure winding 1, low pressure winding 25 equates, is respectively the half of total capacity.
In actual applications, the two low pressure zigzag connection transformers of three-phase have the low pressure winding of two zigzag connections, outlet separately separately, and each low pressure coil volume respectively accounts for 50% of total capacity. So low pressure winding is actually two low-pressure structures.
Because the rated capacity of whole transformer is larger, short-circuit impedance is less, in order to ensure that this pair of low pressure zigzag connection transformer has enough anti-short circuit capabilities, adopted two machine body structures, the device body that is about to the zigzag connection transformer that two three compatible amount are rated capacity half is placed in a fuel tank. Two device body loop constructions are identical, along being arranged in parallel before and after transformer short-axis direction, after the high-voltage parallel of two device bodies, draw, and two devices low pressure winding with it is independently drawn respectively.
