Distribution box is a general term for motor control, which refers to the assembly of switchgear, protective equipment, and auxiliary equipment in enclosed or semi enclosed metal boxes according to wiring requirements. It is a low-voltage distribution device and has a wide range of uses. When a circuit fails, it can automatically cut off the circuit and give an alarm. It is made of non combustible materials and has a wide range of applications, It is widely used in commercial office buildings and processing workshops. As it is an electrified equipment, its operating procedures are also relatively strict. Shandong Hewang Electrical Equipment Co., Ltd. has provided detailed answers for its purpose and operating procedures.
Easy to manage, easy to check in case of circuit failure. The distribution box and distribution cabinet, as well as the distribution panel, are devices that centrally set up switches and instruments. There are two commonly used types of electrical boxes: wooden and iron plate, because electricity consumption is relatively high everywhere nowadays, so iron is used more. Its purpose, of course, is to facilitate power outage and play a role in measuring and judging power outage.
Operating Procedures for Distribution Boxes
The distribution board is the normal operating equipment of the ship's distribution equipment, and relevant personnel are not allowed to pull the board switch.
After the generator set is started, the power screen acceleration switch should be used to manually and slowly accelerate until the generator enters normal working mode, and the voltage and frequency reach the specified values before powering on and transmitting power.
After the distribution board enters the power distribution state, it is not allowed to unplug the power screen up switch without authorization. It is not allowed to use it when the air circuit breaker is not in emergency.
The parallel operation of generators should strictly follow the requirements and regulations of parallel operation, and attention should be paid to phenomena such as reverse power (reverse current) and parallel failure.
When shutting down, the generator load should be cut off first, and then the machine should be shut down without load. It is not allowed to shut down directly with load.
When inserting shore power, the power switches of the shore power screen should be cut off first, and then the correctness of the wiring and phase sequence should be checked. Only after confirming the correctness can the conversion of ship shore power be carried out. It is strictly prohibited to operate under load.
The distribution box should be regularly cleaned and maintained to ensure that the equipment is always in good working condition.
When the generator is working and the engine is working, one should concentrate on thinking and operate with caution to prevent accidents from occurring. Otherwise, personal accident responsibility will be pursued.
The charging and discharging board is the emergency distribution board of the ship. The personnel of the ship should regularly check its working condition to ensure sufficient low-voltage power, and the instrument on the board should grasp the working condition of the magnetic saturation stabilizer.
During normal navigation, all switches on the distribution board should be connected to ensure that the generator can start and respond at any time.
