Vacuum circuit breakers are extensively utilized in the medium voltage level worldwide, but there are still a series issues in the application for higher voltage levels, among which temperature rise is one of the bottlenecks. This paper introduces a new electrode structure with hooked-type support under contact plates, which is helpful to solve the problem of heat generation. Compared with the traditional support structure, the new type of electrode ensures the current passes through the cup wall of the electrodes to generate a strong enough axial magnetic field (AMF) during the breaking. The hook structure is connected with the contact plates pressed by the contact force in the close state, so that the stable temperature rise is lower. In addition, the special hook structure also has a certain anti-welding strength. The simulation results show that the body resistance of the electrode with hooked-type support structure is different at opening and closing states, and the stable temperature rise of the hooked-type structure is significantly lower than that of the conventional support structure in close state with the rated continuous current. The electrode with hook support has a good anti-welding performance in the event of contact welding.

To optimize the dewatering, action should be taken in the press section to avoid additional energy costs in the dryer section - something that pays off quickly. To see to that this is possible one need to measure and analyze especially the press clothing and the most common and important measured parameters are moisture and permeability profiles of the press felts. With new complementary techniques it is now possible to visualize moisture and permeability variations as detailed maps in 2D and 3D, making it possible to pinpoint any problems in press felts. Frequency analysis and felt length are additional properties also measured and presented simultaneously. (The presentation will focus on results from a new instrument released May 2006. The instrument is a further development of the industry de-facto standard from Scanpro and has among other things been complemented with position measurements of both MD and CD).
