Electronic controller i.e. full authority digital engine controller, for e.g. turbojet engine of aircraft, has module insulated thermically such that module remains operational until disconnection of electrical supply of controller by fuse

摘要

The controller (1) has an electronic protection module (5A) for protecting over speed of an engine. An electrical supply block (6A) is intended to supply electricity to the controller. The supply block includes a thermal fuse (7A) adapted to cut off the electrical supply to the controller when temperature of the fuse is greater than cut-off temperature (Tc). The module is insulated thermically such that the module remains operational until disconnection of the electrical supply of the controller by the fuse during overheating the controller.
