Description
Дл устранени вли ни внешних магнитных нолей на показани измерительных ириборов последние обычно злиницаютс магнитными экранами, представл ющими собой массивный стальной цилиндр или р д таких ннлнидров, вставленныхTo eliminate the influence of external magnetic fields on the readings of the measuring instruments, the latter are usually affected by magnetic screens, which are a massive steel cylinder or a series of such nnidders inserted
ОДИ1 в другой. ODI1 to another.
Особенностью предлагаемого экрана вл етс вынолнение его в виде свернутой в спираль ферромагнитной ленты с прослойкой между витками из 11е Магиит} ой ленты.A feature of the proposed screen is its fulfillment in the form of a ferromagnetic tape coiled in a spiral with an interlayer between the turns of the 11th Magiite and the tape.
Такое выполнение экрана, вл сь конструктпвио весь.ма простым и легко вынг)льи1мым, обеснечивает при одной и той же затрате магнитного материала более высокий эффект экранировани , по сравнению с обычными цилиндрическими экранами со СПЛОИ1НЫМИ стенками. В случае использовани предлагаемого экрана дл экранировани электроизмерительных приборов переменного тока oir обладает дополнительным преимунтеством, заключающемс в меньнньх потер х измер емого тока на гистерезис и вихревые токи.Such an embodiment of the screen, which is a construction that is simple and easy to remove, makes it possible, at the same expenditure of magnetic material, to achieve a higher shielding effect, compared to conventional cylindrical screens with CLEVER walls. In the case of using the proposed screen for shielding ac electrical measuring instruments, oir has the additional advantage of minimized measured current losses for hysteresis and eddy currents.
Ыа чертеже схематически показан вид сверху измерите.тьиого прибора, расиоложеииого в предлагаемом зашит1юм экране.The drawing shows schematically the top view of the measuring instrument, which is used in the proposed protection screen.
Как видно из чертежа, экран выно .тнеи из ста.чьной .тенты /, свернутой в внде цилиндра вокруг нрибора параллельно его оси- дл сохранени посто нного рассто ни между витками стальиой ленты вместе с ней иаматываетс лента 2 из немагнитного матернала, наиример из электротехничеекого картона. При таком выиолиеиии экрана магнитные снловые линнн вненн1его магинтного пол , оеобеиио перпендикул рные оси прибора, увод тс него сниральными витками.As can be seen from the drawing, the screen was taken out of the stanchion tents / rolled up in the cylinder vnid around the cylinder in parallel to its axis to maintain a constant distance between the steel rolls of the tape and the tape 2 of the non-magnetic material, cardboard. With such a screen, the magnetic snap lines of the external magnetic field, which are perpendicular to the axis of the device, are carried away by the contour windings.
Предмет изобретен иг The subject is invented
Экран дл защиты измерительных ирнборов от BHeHJHHX магшггных полей, о т л и ч а ю HI, и и с тем, что, с це.;1ью повыгнеин эффекта экра )И1ровани , он выполнен в виде свернутой в спираль ферромагнитной ЛС1ГГЫ с прослойкой между витками из немагнитной ленты.The screen for protection of measuring irnbor from BHeHJHHX of magnetic fields, HI, and with the fact that, from the price. 1 of the screen effect effect, is made in the form of a ferromagnetic curved spiral with an interlayer between the turns from non-magnetic tape.
