Description
Сущность предлагаемого способа контрол внутреннего теплового сопротивлени силового полупроводникового вентил состоит в том, что при любых нагрузках в области допустимых в эксплуатации значений теплового сопротивлени температура гибкого силового вывода ниже температуры корпуса, а начина с некоторого критического значени теплового сопротивлени она становитс И остаетс выше температуры корпуса. Измер разность температур корпуса и гибког силового вывода в момент измеио;::1Я ее знака, фиксируют заданную допустимую величину теплового сопротивлени Способ может быть реализован с помощью стационарных автоматических устройств или с применением переносных диагностических установок.The essence of the proposed method of controlling the internal thermal resistance of a power semiconductor valve is that at any load in the region of allowable values of thermal resistance in operation, the temperature of the flexible power output is lower than the case temperature, and starting from some critical value of thermal resistance, it becomes AND remains above the case temperature. Measuring the temperature difference between the housing and the flexible power output at the time of measurement; :: 1 I of its sign, fix the specified allowable value of thermal resistance. The method can be implemented using stationary automatic devices or using portable diagnostic equipment.
Использование предлагаемого способа дозвол ет организовать посто нный или периодический контроль теплового состо ни вентилей эксплуатируемых преобразователей и обеспечить своевременную замену вентилей при ухудшении из внутреннего теплоотвода что способствует повышению надежности преобразователей и снижению трудозатрат на контроль состо ни вентилей.Using the proposed method allows one to organize permanent or periodic monitoring of the thermal state of the valves of the operated converters and to ensure timely replacement of the valves when the internal heat sink deteriorates, which contributes to increasing the reliability of the converters and reducing the labor costs for monitoring the state of the valves.
