Standard voltage is DC 750V 1 d, using the system power supply to the power supply Rails.Specified in the standard EN 50163 as follows:-The smallest stable voltage is 500V DC-The largest voltage stability is 900V DC-The largest voltage instability is 1000V DC1. electrical systemElectrical systems through verification of the actual application. Each train at least 2 electrical system.To avoid short circuits in the power supply Rails, between the electrical supply system must be insulated from each other.The location of the electrical system to avoid when moving from this area to the other areas lost power supply DC 750V 1 d, in addition, to avoid the bridge separating the power supply Rails zone (if any).Hero electric system that the system needs, including:-The ship's power supply requirements-LimitedKeep the electrical system and other equipment must have enough distance away from each other, at least 70 mm.-Voltage range-Motivation (unitary Board can operate normally in the event only one electrical system to work).-Compatible with the type and characteristics of the ray system power supply.-The size of the power supply rail (perpendicular to the direction of position and horizontal direction)-Abrasive-Pressure exposure (including indirect contact stability in the condition of the ship and the East Rail, contact networks).
