Description

Technical Field

[0001] The utility model relates to the technical field of single-chip computers, in particular to a single-chip computer protection device for an auxiliary exciter. Background Art

[0002] The main function of the auxiliary excitation device is to control the excitation current of the auxiliary synchronous generator so that the output voltage of the auxiliary generator adapts to the changes in speed and load to meet the requirements of the locomotive for the auxiliary system. The auxiliary excitation device requires a single-chip microcomputer. When the single-chip microcomputer is in use, most of the time, the pins of the single-chip microcomputer are directly inserted into the small holes of the mounting plate to achieve the installation of the single-chip microcomputer. The installation and removal of the single-chip microcomputer are mostly done manually by the staff. The manual installation and removal of the single-chip microcomputer by the staff will cause uneven force on the single-chip microcomputer. Since the pins of the single-chip microcomputer are very fragile, uneven force during the installation and removal of the single-chip microcomputer will cause the pins to bend, resulting in damage to the pins, and then damage to the single-chip microcomputer, making it unusable.
