1、 The power distribution cabinet is the eighth industry of the ship's power distribution center and the normal operation of the equipment.


2、 After the generator set is started, it should be accelerated slowly manually through the power panel lifting switch. After the voltage and frequency reach the specified value, the power transmission should be connected until the generator reaches the normal working state.


3、 After the power distribution cabinet enters the power distribution state, it is not allowed to pull out the power panel rising switch at will. The closing switch of air circuit breaker shall not be used in emergency.


4、 The parallel operation of generators must be in strict accordance with the conditions and regulations of parallel trains. Attention must be paid to the phenomena of reverse power (reverse current) and failure of parallel trains.


5、 When the generator is stopped, it shall not stop without load after cutting off the load.


6、 When using shore power, first cut off the power switches of shore power panel, check the correctness of wiring and phase sequence, and then implement shore power conversion after confirming the correctness. Load operation is strictly prohibited.


7、 The distribution cabinet should be cleaned and maintained regularly to ensure that the equipment is always in good working condition.


8、 When the generator works and the turbine personnel operate the power distribution cabinet, they should concentrate their thoughts and operate carefully to prevent the occurrence of accidents. They must be held responsible for personal accidents.


9、 The charging and discharging board is the emergency distribution board of the ship. Commuters should check its working condition frequently to ensure that the low-voltage power is sufficient at any time, and master the working condition of the magnetic saturation regulator through the board instrument.


  1. During normal navigation, all switches of the power distribution cabinet shall be connected to ensure that the generator can be started and used at any time.
