The Impact Of The Alignment Of Moving And Stationary Contacts On The Performance Of High-voltage Disconnecting Switches
Date: | Read: 0
During on-site commissioning, aligning the moving and stationary contacts ensures complete contact between the moving contact and the stationary contact at the end of the closing stroke, guaranteeing the integrity of the overall conductive path. Position mismatch can lead to uneven contact of the contacts, resulting in tilted contact surfaces or offset contact points. This will change the contact resistance distribution and affect the power-on reliability of the High Voltage Disconnect Switch. Proper alignment of the moving and stationary contacts also affects mechanical consistency; the linear motion output by the operating mechanism must match the contact geometry, otherwise, increased friction and rubbing may occur.
