Described rectifying device is shell structure or self supporting structure, adopts bus to adopt aluminum alloy materials.
Compared with prior art, advantage of the present invention is:
1. easy for installation: valve side linearly connects the rectification brachium pontis of double-bridge shaft-type rectifying device and has realized in line dock at busbar to connecting with the cophase counter parallel connection rectifier transformer, reduced need bend, the scene joins a series of unnecessary operations such as hole, make installation procedure from complicated, difficulty is high to oversimplifying;
2. equal mobility improves: rectifier cell symmetry on the brachium pontis bus is installed and is made each bypass elements impedance the same, so avoided the installation owing to element, the current stabilizing factor decline problem that layout causes to a certain extent, equal mobility is increased.
3. loss is low: realize complete in line butt joint, line impedance is little, and busbar arrangement is simple, clear, has reduced the loss of rectifying installation.Brachium pontis bus rectifier cell adopts and is total to the moon, sun is arranged altogether.Shared six roots of sensation rectification brachium pontis (three are total to sun, and three positive altogether) divides front and back or arranges spacing up and down.
4. avoid short circuit: two exchange arms (the moon is total to positive altogether) spacings greater than 600mm in the rectification circuit of employing valve side linearly connection double-bridge shaft-type rectifying device, direct current outlet both positive and negative polarity spacing is greater than 1000mm, thoroughly avoid in the cophase counter parallel connection rectification circuit cophase counter parallel connection rectifier bridge spacing arm little, existed the possibility of short circuit phenomenon between brachium pontis.
5. fail safe improves: valve side linearly connects double-bridge shaft-type rectifying device drawing back owing to the brachium pontis spacing, the space of self leaving in the cabinet is bigger, thereby needn't consider to leave access path behind the cabinet, service equipment is gone into by the Qianmen, is convenient to safeguard, the maintenance safety raising.
6. cooling water channel is oversimplified in the rectifying device, and galvano-cautery is little.
