Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes) and measuring cabinets (boxes), which are the final equipment of the power distribution system. Power distribution cabinet is the floorboard of motor control center.
The power distribution cabinet is used in occasions with scattered loads and few circuits; The motor control center is used in places with concentrated loads and many circuits. They distribute the electric energy of a loop of the superior distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and load control.
Extended data:
Operating procedures of power distribution cabinet:
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 board speed-up switch should be used to manually accelerate slowly 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 power distribution panel into the power distribution state, shall not be arbitrarily pull the power panel up switch, unless an emergency air switch locking switch shall not be used.
Four, generator parallel operation should be strictly in accordance with the requirements and regulations of parallel operation, and should pay attention to the reverse power (countercurrent) and parallel operation failure phenomenon.
Five, stop the generator load should be cut off first, and then no-load parking, not directly stop with load.
Six, shore power, should first cut off the shore power switch, and then check the correctness of the wiring and phase sequence, after confirmed, before the implementation of shore power conversion, it is strictly prohibited to run with load.
Seven, the power distribution cabinet should be cleaned and maintained regularly, so that the equipment is always in good working condition.
Eight, when the generator is working, the engineers should concentrate their thoughts and operate carefully when operating the switchboard to prevent accidents, otherwise they will be investigated for personal accident responsibility.
Nine, the charge and discharge board is the ship's emergency distribution board, the engineer on duty should always check his work, ensure that the low-voltage power is sufficient at any time, and master the work of the magnetic saturation regulator through the ship's instruments.
10. During normal navigation, all switches on the switchboard should be turned on to ensure that the generator can be started and put into use at any time.
XI. I hope the above points will be strictly observed by the members of the Wheel Department.
