CTI121-P Ex 3BDH000741R1 ABB Controller module industrial robot

Description

ABB once designed a new system in CTI121-P Ex 3BDH000741R1,
Energy conversion and power transmission from the whole ship
Starting from the transmission chain, it is found that a
Opportunities to replace traditional communication systems.
From traditional AC power distribution system theory to ship borne
In the conversion of DC power grid principle framework
Since then, the important principle has always been implemented:
Personnel and equipment must be protected in case of obstacles; True
Keep proper selectivity1

After the failure, the system can still operate safely.

Elegant and concise, CTI121-P Ex 3BDH000,741R1 is innovative on the basis of existing elements. ABB uses its shipborne DC power grid to
The same design has been implemented in the power distribution process to produce the most flexible marine power and propulsion system to date. The system
Integrate various DC links on the whole ship, and distribute power through a single 1 kV DC circuit
There is no need to install the main AC distribution board, split rectifier and converter transformer. The shipboard DC power grid combines
The advantages of AC and DC components and systems fully comply with the relevant provisions on selectivity and equipment protection, applicable
For any offshore electrical application up to 20 MW and operating at a nominal voltage of 1 kV DC. And the most
It is commendable that ABB shipborne DC power grid can improve the ship’s energy efficiency by 20% and take up the space of electrical equipment
The room and weight are reduced by 30%.
