THYRISTOR VALVE SECTION AND JACKING DEVICE THEREOF

摘要

Disclosed are a thyristor valve section and a jacking device (2) thereof, comprising an ejector pin (2-2) assembled on a frame of the thyristor valve section, having an axis extending left to right, and used for guiding and moving in the directions left and right during use, wherein a right-hand end of the ejector pin (2-2) is provided with a jacking structure (2-1) used for jacking a left end part of a valve set of the thyristor valve section, a force-bearing structure used for bearing an axial loading force exerted by a corresponding loading mechanism is provided on the ejector pin at the left-hand side of the jacking structure (2-1), and a clamping nut (2-3) used for engaging with a right plate face bracket of a left end plate (3) of the frame encircles the periphery of the ejector pin. Provided is a jacking device (2) with a simple structure and a relatively long service life.
