Abstract

As an indispensable part of the valve development

an appropriate fire prevention design is important forsafe and stable operation of converter valves. This paper introduces a kind of fire prevention device for thyristor con-trol units in UHVDC converter valve. Based on a series of tests

such as the AC withstand voltage and partial dis-charge test

the vibration test

the temperature cycling test

and the fire resistance test for this device

the reliabilityand the fire prevention performance of the fire protection device are verified. Using this device

the converter valvesin Hami and Jinhua stations are upgraded to improve their fire prevention performance. In addition

the design andapplication of the device would be useful for the subsequent design of converter valves.
