Abstract
An assembly method for a DC converter valve includes: assembling a top shielding case: lifting the top shielding case to a designated height via a lifting platform, and then fixedly connecting the top shielding case to lower ends of insulators, fixedly connecting upper ends of the insulators to a truss, the truss being located on the top of a valve hall; assembling valve layers: lifting the valve layers to designated locations in a sequence from top to bottom via the lifting platform; and assembling a bottom shielding case: lifting the bottom shielding case to a designated height via the lifting platform, connecting the bottom shielding case to a lowermost valve layer and suspending the bottom shielding case below the lowermost valve layer via suspension insulators. By means of the present invention, the operation is convenient, a small quantity of devices is used, and the security and reliability are high.
