Power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and measuring cabinet (box), which is the final equipment of power distribution system. Power distribution cabinet is the general name of motor control center. The distribution cabinet is used in occasions where the load is scattered and there are few circuits; The motor control center is used in situations where the load is concentrated and there are many circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control of the load.
First, the power distribution cabinet is the normal operation of the ship’s power distribution center and equipment, and any irrelevant personnel shall not pull the switch on the board.
Second, after the start of the generator set, the power panel speed-up switch should be used to manually and slowly accelerate until the generator enters the normal working state and the voltage and frequency reach the specified value before switching on and sending.
Three, after the distribution board into the power distribution state, shall not be arbitrarily pull the power screen up switch, air switch locking switch shall not be used unless it is an emergency.
Four, parallel operation of generators should be operated in strict accordance with the requirements and regulations of parallel operation, and attention should be paid to the phenomenon of reverse power (countercurrent) and parallel operation failure.
Five, stop the generator load should be cut off first, and then no-load parking, not directly stop with load.
Six, the shore power, should first cut off the shore power switch, and then check the correctness of the wiring and phase sequence, after confirmation, can implement the ship shore power conversion, it is strictly prohibited to load operation.
Seven, the power distribution cabinet should be cleaned and maintained regularly, so that the equipment is always in good working condition.
Eight, generator work, marine personnel when operating the distribution board, should concentrate on thinking, careful operation, to prevent accidents, otherwise will be investigated for personal accident responsibility.
Nine, the charging and discharging board is the ship’s emergency distribution board, and the engineers on duty should always check their working conditions to ensure that the low-voltage power is sufficient at any time, and master the working conditions of the magnetic saturation regulator through the on-board instruments.
10. During normal navigation, all switches on the distribution board should be turned on, so as to ensure that the generator can be started at any time and put into use at any time.
Eleven, the above points hope that the members of the wheel department will strictly abide by them.
