Изобретение относитс  к ycTpo&criBaiM дл  защиты минимального еа р женн  с (выдержкой времени магнитных пускателей и контакторов .This invention relates to a ycTpo & criBaiM for protection of minimum duration (time delay of magnetic starters and contactors.

Известны уст1роЙ1ст1ва дл  защиты, содержащие кнопки «Пуск и «Стоп, два промежуточньгх реле последовательно с одн,И|М -из которых включен диод, а параллельно конденсатор .There are known protective devices that contain the Start and Stop buttons, two intermediate relays in series with one, AND | M - of which the diode is on, and a parallel capacitor is connected in parallel.

С целью повышени  надежеости катушка второго промежуточного реле предложенного устройства через за1мыкающий контакт первого промел уточ.ного реле подключена параллельно жнопже «Стоп.In order to increase the hope, the coil of the second intermediate relay of the proposed device is connected in parallel with the first contact of the first switch of the weighting relay in parallel with the “Stop.

На че|ртеже приведена блок-схема устройства дл  защиты мини мального напр жени , где / - обмотка утравл емого контактора; 2 - кнопка «Пуск, 3 - кнопка «Стоп, 4 - нормально отюрытый блок-контакт контактора , 5 - обмотка первого реле; 6-8 - нормально закрытые контакты первого реле; 9 - обмотка .второго реле; 10 - размыкающий контакт второго реле.The following is a block diagram of the device for protection of the minimum voltage, where / is the winding of the parallel contactor; 2 - “Start” button, 3 - “Stop” button, 4 - normally open contactor contact block, 5 - winding of the first relay; 6-8 - normally closed contacts of the first relay; 9 - winding of the second relay; 10 - opener contact of the second relay.

При нажатии на кнопку 2 контактор включаетс  и через 10ВОЙ блак-контакт 4 -включает обмотку 5 первого реле. Реле включаетс  и контактом 8 подключает параллельно своейWhen the button 2 is pressed, the contactor is turned on and through 10TH BLOCK pin 4 turns on winding 5 of the first relay. The relay is turned on and pin 8 connects in parallel with its

обмотке конденсатор, замыкающем контактом 6 шунтирует кнопку «Пуск, а замыкающим контактом 7 подготавливает цепь включени  обмотки 9 второго реле. При нажатии на кнопку «Стоп ток проходит от питающей сети через обмотку 9 второго реле, через замыкающий контакт 7, замыкающийс  контакт контактора 4 и катущку контактора. Второе реле включаетс  и свои1М размыкаюЩИМ1С  контактом 10 отключает первое реле. Прл это.м отключаетс  контакт 7, благодар  чему полностью првк1ращает1с  ток через О|бмотку контактора 1, и контактор отключаетс .winding capacitor, closing contact 6 bypasses the start button, and closing contact 7 prepares the turn-on circuit of winding 9 of the second relay. When the Stop Current button is pressed, it passes from the supply mains through the winding 9 of the second relay, through the closing contact 7, the closing contact of the contactor 4 and the contactor roller. The second relay turns on its own 1M breaker 1 With pin 10 turns off the first relay. The terminal is disconnected from this terminal, whereby the current through the coil of contactor 1 is fully turned on and the contactor is turned off.
