Description
(5) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ПРОПАДАНИЯ.НАПРЯЖЕНИЯ ФАЗ ВЫЧИСЛИТ ЛЬНОГО УСТРОЙСТВА(5) DEVICE FOR CONTROL OF MISSING. VOLTAGES OF PHASES CALCULATE THE DEVICE
I . , . . I. , .
Изобретение относитс к области контрол пропадани напр жени фаз. и может быть использовано в системах контрол трехфазного напр жени .This invention relates to the field of phase voltage loss monitoring. and can be used in three-phase voltage control systems.
Известно устройство дл контрол пропадани одной и более фаз, содержащее , триод, соединенный с реле, генератор импульсов и выпр митель tl.A device for controlling the disappearance of one or more phases is known, comprising a triode connected to a relay, a pulse generator and a rectifier tl.
Недостатком известного устройства вл етс большое потребление. При наличии во всех фазах напр жени триод открыт и через обмотку реле протекает ток. Кроме того, при пропадании напр жени фаз известное устройство малонадежно , так как на обмотку реле поступают импульсы от генератора, параметры которого измен ютс при воздействии внешней серды и возможно ложное срабатывание.A disadvantage of the known device is high consumption. If there is a voltage in all phases of the voltage, the triode is open and current flows through the relay coil. In addition, when the voltage fails, the known device is not very reliable, since the relay winding receives impulses from the generator, the parameters of which change when exposed to an external core and a false alarm is possible.
Наиболее близким к предлагаемому вл етс устройство, содержащее трехфазный выпр митель, подключенный к фазам сети, к которому подключен вход генератора импульсов, реле и триод.Closest to the proposed device is a device containing a three-phase rectifier connected to the phases of the network to which the input of the pulse generator, a relay and a triode are connected.
.база которого соединена с преобразователем напр жени 2 .The base of which is connected to a voltage converter 2.
Недостатком известного устройства вл етс большое потребление мощности, При налимий напр жени во всех фазах протекает ток через обмотку реле. Известное устройство не обеспечивает формировани изолированного от трех (})азной сети сигнала упреждени дл защиты обрабатываемой информации в A disadvantage of the known device is a large power consumption. When there is a voltage, current flows through the relay coil in all phases. The known device does not provide for the formation of an anticipated signal isolated from three (}) network to protect the processed information in
