Abstract

Тепловой пожарный извещатель Абушкевича, который содержит светодиодный индикатор, анод которого через первый резистор соединен с коллектором первого транзистора и анодом первого диода, катод которого подключен к первому выводу первого конденсатора, а через второй резистор - к базе второго транзистора, коллектор которого соединен с базой первого транзистора, первыми выводами второго конденсатора и третьего резистора, вторые выводы которых подключены к эмиттеру первого транзистора и к катоду второго диода, анод которого подключен к первой входной клемме, а вторая входная клемма подключена ко второму выводу первого конденсатора, к катоду светодиодного индикатора, кроме того, через тепловой сенсор - к первому выводу четвертого резистора, а через пятый резистор - к эмиттеру второго транзистора который отличается тем, что дополнительно содержит третий транзистор, коллектор которого соединен с базой второго транзистора, эмиттер которого соединен с эмиттером третьего транзистора, база которого подключена к первому выводу четвертого резистора, второй вывод которого соединен с анодом светодиодного индикатора и выходом ограничителя тока, вход которого подключен к катоду второго диода и к первому выводу третьего конденсатора, второй вывод которого соединен со второй входной клеммой, а тепловой сенсор выполнен как термистор.Abushkevich’s thermal fire detector, which contains an LED indicator, the anode of which is connected through the first resistor to the collector of the first transistor and the anode of the first diode, the cathode of which is connected to the first output of the first capacitor, and through the second resistor to the base of the second transistor, the collector of which is connected to the base of the first transistors, the first terminals of the second capacitor and the third resistor, the second terminals of which are connected to the emitter of the first transistor and to the cathode of the second diode, the anode of which is connected to input terminal, and the second input terminal is connected to the second output of the first capacitor, to the cathode of the LED indicator, in addition, through the thermal sensor to the first output of the fourth resistor, and through the fifth resistor to the emitter of the second transistor, which differs in that it further comprises a third a transistor whose collector is connected to the base of the second transistor, the emitter of which is connected to the emitter of the third transistor, the base of which is connected to the first terminal of the fourth resistor, the second terminal of which is connected the anode of the LED and the output of the current limiter, whose input is connected to the cathode of the second diode and to a first terminal of the third capacitor, the second terminal of which is connected to the second input terminal, and the thermal sensor is configured as a thermistor.
