Description
Изобретение относитс к коммутаци онной аппаратуре. Известен контактор посто нного тока с бездуговой коммутацией, содер жащий контакты с блоком привода, дио два тиристора, блок управлени , трансформатор, конденсатор и дроссель Г 3 Недостатком этого устройства вл етс его сложность. Наиболее близким по техническим средствам и достигаемому результату к предлагаемому вл етс контактор посто нного тока с бездуговой коммутацией , содержащий контакты с блоком привода, соединенным с блоком уп равлени контактором, и диод, включенньй параллельно контактам и встре но с источником коммутируемого тока /2 . „ Это устройство также недостаточно нгщежно. Цель изобретени - повьшение надежности . Поставленна цель достигаетс тем, что контактор снабжен резистором , импульсным трансформатором i блоком включени трансформатора, включенным мезкду блоком управлени и первичной обмоткой трансформатора, вторична обмотка которого включена последовательно с диодом в цепь, шунтирующую контакты с включенным последовательно с ними резистором. На чертеже приведена схема контактора . Контактор содержит контакты I, диод 2, импульсный трансформатор 3, блок 4 включени импульсного трансформатора , блок 5 привода контактов, блок 6 управлею1 ,и резистор 7. Параллельно контгистам ) подключен диод 2 и вторична обмотка импульсного трансформатора 3. Первична обмотка соединена с выходом блока 4, вход которого подключен к блоку 6. Блок 6 соединен также со входом блока 5.The invention relates to switching equipment. A DC contactor with arc-free commutation is known, which contains contacts with a drive unit, a diode diode, a control unit, a transformer, a capacitor and an inductor G 3. The disadvantage of this device is its complexity. The closest in technical means and the achieved result to the proposed is a DC contactor with arcless switching, containing contacts with a drive unit connected to the control unit of the contactor, and a diode connected in parallel with the contacts and detected with a switching current source / 2. “This device is also not sufficiently reliable. The purpose of the invention is to increase reliability. This goal is achieved by the fact that the contactor is equipped with a resistor, a pulse transformer, and a transformer switching unit, a control unit connected to the circuit, and a transformer primary winding, the secondary winding of which is connected in series with the diode in the circuit and shunting the contacts with the resistor connected in series. The drawing shows a diagram of the contactor. The contactor contains contacts I, a diode 2, a pulse transformer 3, a switch-on transformer switching unit 4, a contact drive unit 5, a control unit 6, and a resistor 7. A diode 2 is connected in parallel to the contistors) and the secondary winding of the pulse transformer 3. The primary winding is connected to the output of the unit 4, the input of which is connected to block 6. Block 6 is also connected to the input of block 5.
