The utility model is a valve saturated reactor with a valve. The purpose is to provide a valve saturated reactor bus bar with compact structure, reliable connection and strong flow capacity. It includes a busbar connecting plate and a busbar welding board for the welded aluminum tube, the busbar connection plate and the busbar welding plate are L shaped, characterized by a convex block on the busbar welding plate, and a circular arc groove on the convex block to match the outer diameter of the welded aluminum tube. The width of the connecting plate is larger than the width of the bus welding plate, and the transition arc is arranged on the connection side of the bus bar connecting plate and the bus bar welding plate. The circular arc groove in the utility model is closely fitted with the aluminum tube, effectively increasing the contact area of the aluminum tube and the busbar, and welding on both sides, which can effectively increase the length of the weld than the traditional single side welding, and greatly improve the current flow capacity. This type of bus structure design has the advantages of compact structure, reliable connection and strong flow capacity.

阀饱和电抗器母排
本技术涉及阀饱和电抗器,尤其涉及阀饱和电抗器的母排。
技术介绍
阀饱和电抗器是高压直流输电换流阀装置中用于保护的关键部件,其目的是为半导体器件晶闸管在开关过程中,对电气回路中产生较高的电流上升率di/dt、电压上升率du/dt起限制作用。从而为晶闸管的换流运行提供了一种可靠而高效的保护部件。母排作为电抗器与换流阀的电气连接件,焊接在阀电抗器的线圈铝管上。随着高压直流输电换流阀电流等级的不断提升,需同时提高阀电抗器母排的通流能力。而母排通流能力的提升必须加大母排的截面积,母排截面积的加大必然导致电抗器进、出水口的加长。为了保证电抗器进、出水口的与外接水路的合理连接,必须控制进、出水口的尺寸在一定的范围内。现在阀饱和电抗器的母排为L形,铝管焊接在L形母排的前端面上,如图1所示,这样的结构母排与铝管的接触面小,电流的通流量小,加上铝管的材料为非易焊接材料,因此,母排与铝管的连接强度低。
技术实现思路
本技术的目的是提供一种结构紧凑、连接可靠、通流能力强的阀饱和电抗器母排。为了达到上述要求,本技术是通过以下方案实现的:它包括母排连接板和供焊接铝管的母排焊接板,母排连接板和母排焊接板成L形连接,其特征是母排焊接板上设有凸块,在凸块上制有与所焊铝管外径相配的圆弧形凹槽,在凹槽上口的两侧各设有作为焊接剖口的斜面,所述母排连接板的宽度大于母排焊接板的宽度,在母排连接板与母排焊接板的连接侧面设有过渡圆弧。根据上述方案设计的阀饱和电抗器母排结构,其有效的连接截面增加了,确保了连接面的电流密度低于要求值。圆弧型凹槽与铝管紧密贴合,有效的增加了铝管与母排的接触面积,两侧 ...
