Abstract
The invention discloses a reactance type vacuum bar-shaped on-load tap switch comprising an insulated installing plate which is installed on a connecting base, and a bar-shaped cam which connects three slide blocks. The insulated installing plate is provided with a three-phase static contact assembly and a three-phase vacuum bubble group. The three slide blocks are slidably configured on guide rods. A moving contact installing base is fixed on each slide block. The lower ends of the three moving contact installing bases respectively extend into the three-phase static contact assembly. Multiple protrusions are configured on the bar-shaped cam in a spacing way. The protrusions drive the moving end of the vacuum bubble to move. The reactance type vacuum bar-shaped on-load tap switch is characterized in that a linear motor is installed on the connecting base. The linear motor drives one of the slide blocks to linearly move along the guide rods in a reciprocating way. The slide block also drives other two slide blocks to linearly move along the guide rods in the reciprocating way via the bar-shaped cam. According to the reactance type vacuum bar-shaped on-load tap switch, a bevel gear transmission device in the prior art is cancelled by a transmission mechanism of the reactance type vacuum bar-shaped on-load tap switch so that the structure is enabled to be simpler and cost is lower.
