Abstract: FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering and can be used to reduce losses of electric energy in three-phase four-wire low-voltage networks with non-uniform and / or asymmetric load and increase throughput capacity of these networks. Device comprises three automatically controlled capacitor units connected between each phase of the network and neutral wire, wherein in each capacitor unit there is one uncontrolled (first) stage, the power of which is designed for a constant component of the PM of the load. Three independent units are used to control PM compensation for each phase. Each unit is connected to its current transformer installed in each phase of the network, and phase voltage of the corresponding phase, which enables to independently determine the power factor for each phase of the network by determining the current value of the power factor independently for each phase of the network and comparing it with the set values. If current value of power factor is less than allowable value, signal is sent to increase capacitance of capacitor plant due to controlled capacitor of this phase (C, C, C). Otherwise capacitance of capacitor plant will decrease. As a result, the device will perform independent one-phase PM compensation.EFFECT: technical result consists in reduction of losses in general-purpose electrical networks up to 1,000 V with blind-earthed neutral and increase in their throughput by phase-by-phase regulation of compensation of PM when using constant stage in control system.1 cl, 1 dwg

Abstract: Изобретение относится к медицине, а именно оториноларингологии. Используют штыковидный пинцет с двумя браншами. Под контролем эндоскопа 0 градусов в полость носа через левую половину вводят одну браншу штыковидного пинцета. Вторую браншу располагают на коже пирамиды носа и продвигают дистально. Внутреннюю браншу ведут по верхней стенке полости носа по перегородке носа, а наружную - по коже пирамиды носа до назиона. После достижения наружной бранши пинцета назиона оценивают положение внутренней бранши пинцета, которая будет указывать на область проекции передней стенки лобной пазухи и, соответственно, на переднюю границу высверливания. Внутреннюю браншу пинцета вдавливают в слизистую оболочку полости носа и нажатием кончиком бранши на слизистую оболочку производят в ней отверстие. Пинцет смещают латерально к медиальному углу глаза и фиксируют положение внутренней бранши пинцета, которая будет указывать на переднелатеральную границу высверливания. Аналогично определяют переднюю границу высверливания через противоположную половину носа. Нажатием кончиком бранши на слизистую оболочку производят в ней отверстие, отмечая на слизистой пограничную точку. Скальпелем производят разрез слизистой оболочки крыши полости носа по точкам, отмеченным пинцетом, с формированием передней линии высверливания. Спускаются на перегородку носа, формируя окно в ее верхних отделах, отступя кпереди от границы высверливания на 5 мм, вниз до уровня нижнего края средней раковины и кзади до переднего края средней раковины и вверх до крыши полости носа. После отсепаровки слизистой оболочки и обнажения кости передней линией высверливания становится край слизистой оболочки передних отделов крыши полости носа. С помощью алмазного назального бора производят высверливание кости по определенной ранее линии высверливания, двигаясь из стороны в сторону. Спиливание кости приводит к обнажению просвета правой и левой лобных пазух на уровне их передней стенки. Способ позволяет проводить вмешательство без применения навигационной системы, более точно определять переднюю границу высверливания дна лобных пазух, повысить эффективность и безопасность расширенной эндоскопической фронтотомии. 2 ил., 1 пр.
