传统数字电路启动保护继电器在发生内部触点粘连或卡死时,即使数字电路已经输出一个断开信号,也不能将启动机与发动机脱开,这样很容易造成启动机烧毁或飞轮齿圈损坏问题。康明斯原装进口欧Ⅲ电控发动机都装有ECU(电控模块)。ECU对整机电源质量要求比较高,当电源电压不足时发动机不能正常工作。因此需要在正常启动保护电路中,增加发电机状况检测电路,以保证只有在发电机正常发电的情况下才能启动。
Traditional digital circuit start protection relay In the event of internal contact adhesion or stuck, even if the digital circuit has been output a disconnect signal, it can not disconnect the starter and the engine, it is likely to cause burned starter or flywheel ring gear damage problem . Cummins imported Euro Ⅲ electric control engine are equipped with ECU (electronic control module). ECU on the whole power quality requirements are relatively high, when the power supply voltage is insufficient, the engine can not work properly. Therefore, it is necessary to increase the generator condition detection circuit in the normal starting protection circuit to ensure that it can be started only when the generator is normally generating electricity.
