Description

The main distribution board is a very important part of ship electrical equipment, which is a necessary part for distributing the electricity generated by ship generators to other equipment on board. At the same time, the distribution of electricity is to achieve control, monitoring, on/off, and protection of electrical equipment.(https://www.weikunfadacai1.com/)

The composition of the main distribution board mainly includes generator control screen, load screen, parallel screen, busbar, etc.

The control screen is mainly used to protect, regulate, monitor and control the generator set. In order to achieve monitoring of each generator set, each generator set has its own separate control screen.

The main components of the control screen include the generator main air switch, excitation control system, measurement coils, and instruments. The main control switch is used to control the generator to transmit electrical energy to the busbar, and can also play a protective role. It is mainly used to quickly cut off the faulty circuit in case of short circuit, overload, reverse power, and low voltage faults in the system to protect the generator. The excitation control system, also known as the voltage regulation system (adjusting excitation means adjusting reactive power to ensure the correct power factor of the power grid), is mainly used to ensure that the generator automatically maintains a constant voltage output as much as possible to meet the stable voltage requirements of ship power consumption. The main measurement section includes conversion switches, instruments, etc.

 

The load screen is mainly composed of air circuit breakers, which can achieve the distribution of electrical energy from the busbar to various electrical appliances or distribution boxes.

The parallel screen mainly includes reactors, main contactors, and synchronous meters.

A busbar is a working section line made of copper bars that connects the main switch of a generator and the switch of electrical appliances.

  What are the common faults and troubleshooting methods for the main distribution board?

 1. When the ship is operating on water, it is often in a bumpy state, causing frequent vibration of the main distribution board. Therefore, the fault mainly occurs in areas with strong vibration. Therefore, it is necessary to regularly check the cause of the vibration and eliminate it to ensure that its vibration frequency is separated from the resonance speed, and replace the vibration damping base;

  2. Regular cleaning should be carried out on components such as dust covers and terminal blocks to prevent static electricity from generating sparks, and the screws of the terminal blocks should be tightened regularly to prevent poor contact;

  3. Regularly inspect the instrument panel of the equipment, mainly to check whether the pointer is normal, especially when the load starts or stops, it is necessary to observe whether the pointer’s action is normal, and at the same time, regularly calibrate or replace the instrument.

  4. Confirm whether the working status of the protective device is normal, and regularly maintain the protective device;

  5. By observing the changes in the control instrument, confirm whether the contact between the conversion switch and the control switch is good.
