Предложение относитс  к созданию малореактивных резисторов и образцовых катушек сопротивлени ,  вл ющихс  элементами электроизмерительных схем и устройств посто нного и переменного тока.The proposal relates to the creation of low-reactive resistors and exemplary coils of resistance, which are elements of electrical measuring circuits and devices of direct and alternating current.

Известны способы изготовлени  малореакTHBHbix сопротивлений посредством намотки резистивного элемента бифил рно на металлический каркас и последующего уменьшени  реактивной составл ющей (подгонки).Methods are known for manufacturing low-resistance BHbix resistances by winding a resistive element bifilically on a metal frame and then reducing the reactive component (fit).

Недостатком известных способов  вл етс  невозможность изменени  параметров в процессе изготовлени , сложность подгонки и невысока  точность.A disadvantage of the known methods is the impossibility of changing the parameters in the manufacturing process, the difficulty of fitting and the low accuracy.

По предлагаемому способу уменьшение реактивной составл ющей производ т изменением местами пр мого и обратного привода бифил ра. Это позвол ет упростить процесс подгонки и увеличить его точность.According to the proposed method, the reduction of the reactive component is made by changing the places of the forward and reverse drive of the bifil. This simplifies the fitting process and increases its accuracy.

Способ по сн етс  чертежами, где на фиг. 1 изображена резистивна  катущка, намотанна  одновременно двум  бифил рными петл ми А и В; на фиг. 2 приведена схема, по сн юща  процесс подгонки сопротивлени .The method is explained in the drawings, where in FIG. Figure 1 shows a resistive coil wound simultaneously with two bifillary loops A and B; in fig. 2 is a diagram illustrating the process of fitting a resistance.

Предлагаемый способ по сн етс  на примере процесса изготовлени  и подгонки сопротивлени  ом. Концы двух бифил рных петель сопротивлением по 200 ом закрепл ют на металлическом каркасе и производ т одновременную спиральную намоткуThe proposed method is illustrated by the example of the process of manufacturing and fitting the resistance. The ends of two bifillary loops with a resistance of 200 ohms are fixed on a metal frame and are simultaneously wound helically.

сразу в четыре провода. Перед намоткой поД один из проводов какого-нибудь бифил ра завод т эластичную нить, зацепл   ею другой провод этой петли. После окончани  намоткиimmediately four wires. Before winding the wire, one of the wires of some bifil- ary plant t is an elastic thread; it hooks the other wire of this loop. After winding

оба бифил ра соедин ют параллельно дл  получени  сопротивлени  100 ом. При этом токи во внутренних проводах петель А и В протекают в противоположных направлени х (см. фиг. 1).Both biphils are connected in parallel to obtain a resistance of 100 ohms. In this case, the currents in the internal wires of loops A and B flow in opposite directions (see Fig. 1).
