RECTIFIER V-TPE 500-275-1-UHL5 WITH MICROPROCESSOR OPERATIONAL SYSTEM |
|
Area of use – electrified transport current supply with microprocessor or analog (by customer’s request) motor control system, (trolley locomotives) in coal mining developments which are not dangerous to gas and dust, in I and II categories dangerous to gas and dust mining developments with fresh air streaming also. It is applying in underground metro developments too. The microprocessor operational system provides thyristors work control and diagnose. It allows working at any supply voltage phases interchange order, provides connection to the ICS (industrial control system) through the RS485 channel. |
It guaranties “Safety regulations in coalmines NPAOP 10.0-1.01-
The rectifier is electrical equipment with isolation level 1 (RN1).
The rectifier power section is built on the base of three-phase bridge rectification scheme.
Parallel work of two rectifiers on common overhead line is foreseen.
Rectifier conditional shorthand structure:
V-TPE 500-275-1-UHL5
V – converter type – rectifier;
T – power supply current type – three-phased;
P – output current type – direct;
E – cooling method – natural air cooling;
500 – rated output current, A;
275 – rated output voltage, V;
1 – microprocessor operational system (in case of ordering V-TPE-500-275 with analog operational system the number “
UHL – climate fulfillment type according to the GOST 15150-69;
5 – placement category according to the GOST 15150-69.
The rectifier is executed constructively as two sides maintaining metal cabinet divided into two sectors: power sector, with IP22 protection level and control system sector with IP54 protection level according to the GOST 14254-96.
The power sector serves as airway and thyristors with coolers are placed in it. In the control system sector automatic switcher, fuses, house transformer, control and operation plates are placed.
