The invention discloses redundant controller switching devices arranged side by side and used for an emergency diesel-electric generator set. The redundant controller switching devices comprise a first controller and a second controller. A first main relay and a first self-inspection relay are integrated on the first controller and are each provided with a signal output port, and a second main relay and a second self-inspection relay are integrated on the second controller and are each provided with a signal output port; the first controller is further provided with a first detection signal input port and a first confirmation signal input port, and the second controller is further provided with a second detection signal input port and a second confirmation signal input port; the signal output port of the first main relay is connected with the second detection signal input port, and the signal output port of the second main relay is connected with the first detection signal input port; the signal output port of the first self-inspection relay is connected with the second confirmation signal input port, and the signal output port of the second self-inspection relay is connected with the first confirmation signal input port.
Description
technical field [0001] The invention relates to a parallel configuration of a redundant controller switching device for emergency diesel generator sets in the field of diesel generator sets. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as prime mover and drives synchronous generator to generate electricity. This is a power generation device with quick start, convenient operation and maintenance, low investment and strong adaptability to the environment. Diesel generator set is mainly divided into four parts: diesel engine, generator, control system, electrical system. The control system controls the diesel generator set to run according to the set parallel state and has functions such as alarm and shutdown in the fault state. The diesel generator set control system can accurately and quickly adjust the operation of the diesel generator set, and keep the electrical equipment in good and consistent condition. machine...
