Detail Description
1. Description and Data
Description:LTT thyristor valve
Capacity:3000MW
Rated DC voltage :Ud=±500kV
Rated DC current:Id=3000A
Rectifying circuit:3 phase 12 impulse bridge rectifying circuit
Cooling:forced deionized water cooling system
Firing: Light trigger thyristor, BOD protection integrated inside thyristor, PLC online monitoring on thyristor failure
2. Technical characteristics:
Standard valve module assemblied with thyristors and heatsinks
Pure (deionized) water cooling system in thyristor and reactor modules
water cooled damping resistor which can keep safe on tempory high-loss state
Number of key parts reduced, which lower the failure rate and make maintanance easy
Instead of former high potential electronic circuit, BOD protection integrated inside LTT thyristor
This product can not only satisfy the need of HVDC valve, TCR valve, but also have bright future in some new industrial fields like AC and DC active filter, STATCOM, TCSC, etc.
