реле 1 и электродвигател  7 При обрыве любой из фаз 8,9ДО напр жение между соответстеуюпшмн электродами уменьшаетс  и реле 1 также производит отключение элетродвигатеп  7.5relay 1 and electric motor 7 If any of the 8.9-D phase is broken, the voltage between the respective electrodes decreases and relay 1 also switches off the electric motor 7.5

Дл  более четкого опипочени  репе i при обрыве одной из фаз 8,9,10 в цепи ано да и управл ющего электрода тиристора 3 могут быть включены пороговые элементы, например динисторы.ЮFor a clearer tipping of turnip i, if one of the phases 8,9,10 is broken in the circuit of the anode and the control electrode of the thyristor 3, threshold elements, such as dinistors, may be included.

Дл  теплового контрол  всех обмоток электродвигател  в непосредртвенной близости с каждой из обмоток может располагатьс  отдельный позистор, который включает & цеоь управлени  тиристора 3 последшатель, но с позистором 6,For thermal control of all windings of an electric motor, a separate posistor can be positioned directly in front of each winding, which includes & the thyristor control center 3 is the last, but with a posistor 6,

Взамен датчика - позистора 6 могут быть использованы и другие датчики, например , датчик из легкоплав здегос  сплава вуда,Instead of the sensor - posistor 6, other sensors can be used, for example, a light alloy alloy sensor of a wooden alloy,

ч 568109h 568109

Предложенное устройство может найти широкое применение в зашитых не только трехфазных электродвигателей, но и дру гих токоприемников.The proposed device can be widely used in wired not only three-phase electric motors, but also other current collectors.
