Abstract: Изобретение относится к области электротехники. Технический результат заключается в повышении надежности переключения потребителей, потерявших питание, на резервный источник. Согласно способу автоматического включения резерва, измеряют напряжение Uна шинах потребителей и ток Iна выключателе ввода питания (ВВП), подключенных с помощью ВВП к рабочему источнику питания. Постоянно контролируют положение ВВП с помощью первого и второго реле его положения. Определяют характеризующий потерю питания потребителями угол ϕ между напряжением Uи током I. Сравнивают напряжение U, ток Iи угол ϕ с заданными величинами и, если они превышают их, подают сигнал на отключение ВВП. Затем включают первый секционный выключатель (СВ), измеряют ток Iв его фазах и определяют сопротивление отношением Z= U/I. Сравнивают ток Iс заданной величиной тока Iи сопротивление Zс величиной сопротивления Z, и, если величина тока Iболее либо равна заданной величине тока I, или Zменее либо равно Z, то через выдержку времени tподают сигнал на отключение первого СВ. Если величина тока Iменее заданной величины тока I, и Zболее Z, то переключают выдержку времени на tболее t. Если через время более времени tпосле включения первого СВ выключателя окажется, что величина тока Iболее либо равна заданной величине тока Iили Zменее либо равно Z, то через время tпосле момента увеличения тока Iв фазах первого СВ до Iили уменьшения Zдо Zподают сигнал на отключение первого СВ. Дополнительно вводят второй СВ в горячий резерв. Если после подачи сигналов на отключение ВВП он отключился и есть сигнал от первого или второго реле положения ВВП и первый СВ не включился, то включают второй СВ. Далее, сразу после момента включения второго СВ дополнительно измеряют ток Iв его фазах и определяют сопротивление отношением Z= U/I. Сравнивают ток Iс заданной величиной тока Iи отношение Zс величиной сопротивления Z, и, если величина тока Iболее либо равна заданной величине тока I, или Zменее либо равно Z, то через выдержку времени tподают сигнал на отключение второго СВ. Если величина тока Iменее заданной величины тока I, и Zболее Z, то переключают выдержку времени на t. Далее, если после включения второго СВ окажется, что величина тока Iболее либо равна заданной величине тока I, или Zменее либо равно Z, то через время tпосле момента увеличения тока Iв фазах второго СВ до Iили уменьшения Zдо Zподают сигнал на отключение второго СВ. 1 ил.

Abstract: FIELD: agriculture. 
     SUBSTANCE: invention relates to methods for storage of agricultural products of field crop cultivation and horticulture. Method for treatment of vegetables, fruit, grain and leguminous crops and products manufactured from them consists in their blowing by electric arc air at atmospheric pressure. First, a plasma source is generated with DC arc discharge in plasma-forming gas, for example in argon or nitrogen, when using a rod tungsten cathode, having a water-cooled closure in its outer part and facing a water-cooled nozzle copper anode, a hot internal conical end face. On the anode channel section along the normal line to the gas-discharge plasma flow there is mixed circular air flow creating distributed anode binding with specific erosion of the anode at level of 10 -10  g/Cl and further flowing along the plasma source axis in the form of a mixture with gas-discharge plasma. Behind the plasma source nozzle cut, spatial distributions of temperature and NO and OH radical concentrations are measured at selected gas flow rates and electric arc discharge parameters, which create average concentrations of said radicals of not less than 500 ppm, and determining minimum allowable removal of processed objects from the plasma source nozzle edge, wherein its temperature is 30 °C. After that selected objects are blown with prepared by that way plasma jet using parameters determined for it. 
     EFFECT: technical result is longer storage life of agricultural products, preservation of its presentation and nutritive value at maintenance in normal conditions without temperature reduction and without additional packages, coatings and gases, and also reduction of danger of such treatment by service personnel.

Abstract: FIELD: electricity. 
     SUBSTANCE: invention relates to automatic control of high-voltage rectifier power supply units of electric filters of gas purification by rectified high-voltage current. Breakdown occurs in settling space of electric precipitator during operation of system "rectifier unit - electric filter". Correction of recovery time after breakdown in interelectrode space of electric filter field and duration of quenching after spark breakdown is performed automatically with certain periodicity. In a multi-field electric filter, a static mode is successively set on each subsequent field of the electrostatic precipitator, in which there are no spark breakdown. At the same time on the previous field operating in automatic mode parameters of speed of voltage increase, depth of development and duration of pause of the suppression are changed. When minimum voltage values and maximum current values are reached, data on speed of voltage rise, working depth and duration of quenching pause on the previous filter field are recorded on the next field. After that, the changed parameters are fixed and the process proceeds to the following filter fields. 
     EFFECT: higher degree of gas purification due to increase of average voltage on electric filter in mode of spark and arc breakdowns.
