Abstract
The invention relates to the technical field of transformers, in particular to a transformer capable of driving eight tubes simultaneously. In the transformer, a return wire bobbin bracket and a non-return wire bobbin bracket share a group of iron cores, and are arranged on a circuit board side by side; and the iron cores are contacted with each other to form two respectively independent magnetic paths for the return wire bobbin bracket and the non-return wire bobbin bracket. By adopting a double high-voltage technique and the return wire bobbin bracket and the non-return wire bobbin bracket with a two-in-one structure, the transformer can drive eight tubes simultaneously, and is cheaper than four transformers capable of driving two tubes and two transformers capable of driving four tubes; the safe use of the transformer is ensured; moreover, the transformer facilitates wiring layout on the circuit board.
