Изобретение относитс к электротехнике и может быть использовано дл управлени электрическим и температурным режимами установки, в которых нагрев и термообработ ка деталей производ тс с помощью сильноточного тлеющего разр да.The invention relates to electrical engineering and can be used to control the electrical and thermal conditions of a plant in which parts are heated and heat treated using a high-current glow discharge.
Известно устройство автоматического управлени и контрол пускового периода и работы процесса термообработки с помощью тлеющего разр да, содержащее блок определени частоты дугообразовани , св занный с разр дной камерой, программный регул тор, соединенный с регулируемым источтисом питани , и регул тор режима обработки. В начальный период обработки напр жение источника питани повышаетс по программе, заданной программным регул тором. При возникновении дугового разр да источник питани отключаетс на врем , достаточное дл деионизации разр дного промежутка. В зависимости от частоты дугообразовши программа может оставатьс иа достигнутом уровне, возвращатьс на предыдущую ступень или к исходному состо нию. По окончании програмРАЗРЯДАA device for automatic control and monitoring of the start-up period and the heat treatment process using a glow discharge, containing an arc frequency detection unit associated with the discharge chamber, a software controller connected to an adjustable power supply, and a controller for the processing mode are known. In the initial processing period, the voltage of the power source rises according to the program set by the software controller. When an arc discharge occurs, the power source is turned off for a time sufficient to deionize the discharge gap. Depending on the frequency of the arcing, the program may remain at the reached level, return to the previous step or to the initial state. At the end of the program
мы программный регул тор отключаетс , и далее продесс обработки может производитьс вручную или автоматически с помощью регул тора режима обработки f1.The software controller is turned off, and further processing can be done manually or automatically using the processing mode controller f1.
Недостаток указанного устройства заключаетс в том, что ход программы зависит только от частоты дугообразовани и не учитывает скорости изменени температуры деталей, котора при уменьщении частоты дугообразовани может превысить предельные значени , при которых возникают деформации деталей.The disadvantage of this device is that the program flow depends only on the frequency of arcing and does not take into account the rate of change of temperature of the parts, which, as the frequency of arcing decreases, may exceed the limit values at which deformations of parts occur.
