FIELD: electrical engineering. SUBSTANCE: plug has shroud with printed-circuit board, spark gap, slider, spring, ground plate, and warning device. Shaped fusible part of plug is held under minimal force and has small number of components permitting automated manufacture with high economic efficiency. Spring-loaded slider is held within shroud by supporting surface and internal edge of shroud; shaped fusible part is held under minimal pressure of slider. EFFECT: improved reliability of overvoltage protection and warning about operation of trouble-free mechanism of system. 4 cl, 6 dwgd |
