voltage of 40-200v.
Single unit 12 pulse, two units in parallel to form a 24 pulse rectifier system.
2.3 the rectifier line adopts double inverse star with balance reactor, which is fixed inside.
2.4 electrical conditions for normal use
2.4.1 power supply voltage: 20kV ± 5%
2.4.2 frequency: 50Hz ± 0.5
2.4.3 number of phases: 3
2.4.4 power supply: AC380 / 220V ± 5%
2.4.5 control protection: AC220V ± 5% or dc220v
Frequency: 50Hz ± 0.4
3. Cooling of rectifier:
3.1 cooling method: use deionized high-purity water for cooling.
3.2 layout of cooling water circuit: the main manifold of component cooling water circuit is located at the bottom of rectifier cabinet and adopts pure water cooling mode.
3.3 cooling water circuit materials: the cooling water pipe,nozzle and flange of rectifier cabinet are made of stainless steel or PVC materials, and the water pipe Selection of high quality anti-aging, corrosion resistant hose.The pressure and temperature measuring points are installed in the middle of the manifold and in the pure Thermal
resistance for centralized monitoring (installed in rectifier cabinet) shall be set at the water outlet pipe.
3.4 pressure of cooling circulating water: the water pressure shall not be less than 0.10MPa and 0.15Mpa in normal operation.
4. Installation method:
The rectifier device is fixed indoors, located on both sides of the rectifier transformer and directly grounded.
5. Application: graphitized products.
6. Natural conditions:
Rectifier room absolute air temperatureat maximum site ambient °C 50 
Pollution level: Grade III
