The utility model is specifically related to an arc high voltage package, including framework, magnetic core, primary winding, secondary winding, the magnetic core hole that is inserted to magnetic core is provided in the framework, the secondary winding area that winds the secondary winding is provided with in the framework circumference, the primary winding is the shaped winding, the one end of framework in the magnetic core hole axial direction is provided with the positioning block for fixing primary winding, primary winding and secondary winding are provided with and concentric along the magnetic core hole axial side by side. Compared with the form that the traditional is wound on the framework in turn, need not winding insulation structure between the two, at the same time, since the primary winding is the shaped winding, only needs to process it into the winding in production, then can complete the installation after fixing it on the positioning block, need not winding it on the positioning block again through the adhesive tape to its circumference to make its structure stable, not easy to scatter, greatly saves the production procedure and cost of the device.

The utility model discloses a louver blade fixing device and a louver, the louver blade fixing device comprises a first fixing plate and a second fixing plate connected with the first fixing plate, the first fixing plate and the second fixing plate are respectively provided with a plurality of first fixing parts and second fixing parts at intervals, the first fixing parts and the second fixing parts are arranged oppositely, and the first fixing parts and the second fixing parts are arranged oppositely. A first limiting groove is formed between every two adjacent first fixing parts, a second limiting groove is formed between every two adjacent second fixing parts, and the first limiting grooves and the second limiting grooves are arranged in a staggered mode so that piece clamping grooves used for obliquely containing and fixing shutter pieces can be formed between the first limiting grooves and the second limiting grooves which are adjacent. Based on the louver blade fixing device, the louver blades are more convenient to mount and operate, the stability and the usability of the louver blades are improved, and the cost is greatly reduced.
