SU1374291A1 - Magnetic core of ballast device choke - Google Patents

Abstract

The invention relates to electrical engineering, in particular to ballast throttles. The aim of the invention is to reduce material consumption. The magnetopoint consists of two L-shaped halves of the rom 1, an I-shaped rod 2 with a winding 3 located on it. Between the rom 1 and the rod 2 there are two identical non-magnetic gaps 4. The b-pattern 1e of the rom plate is made with parallel beams at an angle that provides a wedging effect. To tighten both halves of the rom I between themselves and fixing them with respect to the rod 2, a casing 5 is installed, which, deforming into the recess 6 of the L-shaped plates of the frame, fits them tightly. 1 hp f-ly, 2 ill. with f

The invention relates to a magnetic conductor composed of stamped plates, used as an element of chokes, ballast devices for gas discharge lamps.

The aim of the invention is to reduce the material consumption of droplets.

Figure 1 shows schematically the magnetic core of a ballast device d for gas discharge lamps, a section; figure 2 - plate of the magnetic circuit.

The magnetic circuit of the ballast device for gas discharge lamps consists of a two-half L-shaped p-15 mA I, 1-shaped rod 2 with a winding 3 on it. Between the rom 1 and the rod 2 there are two identical non-magnetic gaps 4. L-shaped plates made with parallel-20 bevels, made at an angle greater than 0 ° and less than 90 °, which creates a wedging effect during tightening.

For tightening both halves of the ram 1 between themselves and fixing them with respect to the – rod 2, a casing 5 is used,
