Abstract

FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and is used in powerful power supply circuits. The battery is connected between the source and the load and filters (suppresses) impulses and regular ripple between the lines (4) of the capacitor circuit (1). When common-mode impulses appear on lines (4), they are filtered by capacitors (2). At the same time, capacitors (2) are calculated for a lower voltage, which simplifies the installation, reduces its dimensions.
EFFECT: installation is simplified and its dimensions are reduced.

Description

Предложение относится к электротехнике и используется в мощных цепях электропитания. Широко известен патент РФ на изобретение 216883, состоящий из линейных конденсаторов, магнитосвязанного дросселя и другого конденсатора. Однако такой фильтр не подавляет синфазные импульсы. Прототипом изобретения является патент РФ на изобретение 2381614, содержащий цепь конденсаторов линейных и фазных, которые одним выводом заземлены. Недостаток такого устройства состоит в относительно низкой большой сложности. Техническим результатом предложения является упрощение. Этот результат обеспечивается за счет того, что цепь линейных конденсаторов состоит из не менее трех последовательных конденсаторов, к симметричным точках которых присоединены вторые выводы фазных конденсаторов. На чертеже представлена схема устройства, где обозначены: 1-линейные, а 2-фазные конденсаторы, 3-заземление, 4-линии. Батарея включается между источником и нагрузкой и фильтрует (подавляет) импульсы и регулярные пульсации между линиями 4 (или полюсами) цепью конденсаторов 1. Несколько последовательных конденсаторов 1 применяются из-за большого напряжения между линиями. При возникновении на линиях 4 синфазных (однонаправленных в обоих фазах) импульсов воздействий, они фильтруются конденсаторами 2. Конденсаторы 2 при этом рассчитываются на меньшее напряжение, что упрощает установку, уменьшает ее габариты.The proposal relates to electrical engineering and is used in high-power power supply circuits. RF patent for invention 216883 is widely known, consisting of linear capacitors, magnetically coupled inductor and another capacitor. However, such a filter does not suppress common-mode pulses. The prototype of the invention is the RF patent for invention 2381614, containing a chain of linear and phase capacitors, which are grounded by one terminal. The disadvantage of such a device is the relatively low high complexity. The technical result of the proposal is to simplify. This result is ensured due to the fact that the chain of linear capacitors consists of at least three series capacitors, to the symmetrical points of which the second leads of the phase capacitors are connected. The drawing shows a diagram of the device, where indicated: 1-line, and 2-phase capacitors, 3-ground, 4-lines. The battery is connected between the source and the load and filters (suppresses) pulses and regular ripple between the lines 4 (or poles) of the capacitor chain 1. Several series capacitors 1 are used because of the high voltage between the lines. When 4 in-phase (unidirectional in both phases) impact pulses appear on the lines, they are filtered by capacitors 2. Capacitors 2 are calculated for a lower voltage, which simplifies the installation and reduces its dimensions.
