Description

11ред:Ме|о м изобретени   вл етс  устройство дл  защиты от сверхтоков чувствительных электрических приборов, работающих в п,ел х посто нного или пульсирующего токов , соаержащее максимальное токовое ре е, которое при срабаты.вании шунтирует защищаемый прибор .11red: The invention is a device for protection against over-currents of sensitive electrical devices operating in n, constant or pulsating currents, containing the maximum current flow that shunts the protected device when activated.

В предлагаемом уст эойстве благодар  наличию конденсатора, включенного пара.тлельно защищаемому нрибору, достигаетс  возможность предотвращени  повреждени  нрибора в период между по влением авар ийпого напр жени  и моментом срабатывани  реле.In the proposed device, due to the presence of a capacitor, a switched-on pair of a protected device, it is possible to prevent damage to the device during the period between the occurrence of an emergency voltage and the moment the relay is triggered.

На чертеже представлена электрическа  схема предлагаемого устройства , в которой прин ты обозначени : /-реле максимального тока с нормально разомкнутыми контактами , токова  катушка которого включена последовательно, а нормально разомкнутые контакты- параллел1)Но зан1пщаемому прпбору 2; 3-конденсатор, включенный параллельно защищаемому прибору.The drawing shows the electrical circuit of the proposed device, in which the following designations are accepted: / -switch overcurrent with normally open contacts, the current coil of which is connected in series, and normally open contacts-parallel1) But the device 2; 3-capacitor connected in parallel with the protected device.

Через токовую катушку реле 1 проходит суммарный ток прибора 2 и конденсатора 3. зтот ток превысит ток трогани  реле, то поедеднее сработает и защунтирует защ.нндаемый прибор.The total current of the device 2 and the capacitor 3 passes through the current coil of the relay 1. This current will exceed the current triggered by the relay, then the last time it will work and will protect the protective device.

При резком повышении напр жени  больша  часть тока срабатывани  реле пройдет через конденсатор , что предохранит от повреждени  прибор 2 до момента срабатывани  реле /.With a sharp increase in voltage, a large part of the relay operating current will pass through the capacitor, which will prevent the device 2 from damaging until the relay triggers.
