Description

Включение диодов 12 позвол ет уменьшить перенапр жени , возникающие на симисторах 8-10 при обрыве тока. При коротком замыкании минусовой шины на землю работа устройства аналогична .The inclusion of diodes 12 makes it possible to reduce the overvoltages that occur on the triacs 8-10 when the current is interrupted. In case of short circuit of the negative bus to the ground, the operation of the device is similar.

Применение предлагаемого устройства позвол ет упростить защиту и повысить ее надежность в различных установках индукционного нагрева металлов .The use of the proposed device allows to simplify protection and increase its reliability in various induction heating plants.
