Embodiment Construction

[0025] see Figure 1 to Figure 3 , the reactive vacuum strip-type on-load tap-changer shown in the figure includes a connecting base 100, and an insulating mounting plate 300 in a strip-shaped structure is installed on the bottom surface of the connecting base 100.

[0026] The insulating mounting plate 300 has opposite fronts 310 and backs 320 , on the insulating mounting plate 300 close to the upper edge, there is a long slot 340 that is closed at both ends and runs through the fronts 310 and the back 320 along its length.

[0027] Three-phase static contact assemblies 410 , 420 , 430 are installed at intervals along the length direction of the insulating mounting plate 300 on the front 310 of the insulating mounting plate 300 close to the lower edge of the insulating mounting plate 300 .

[0028] Each phase static contact assembly 410, 420, 430 includes a pair of support plates 411, 412, 421, 422, 431, 432 and a static contact mounting plate 413, 423, 433, the static contac...

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.

Description

technical field [0001] The invention relates to the technical field of on-load tap changers, in particular to a reactive vacuum bar-shaped on-load tap changer. Background technique [0002] German MR company has applied for Chinese invention patents with the following application numbers in China: 1. The application number is 201380020450.0, and the name of the invention is "on-load tap-changer"; 2. The application number is 201380020745.8, and the name of the invention is "on-load tap-changer" ;3. The application number is 201380020207.9, and the name of the invention is "on-load tap-changer"; 4. The application number is 201380020742.4, and the name of the invention is "on-load tap-changer". The core of the above-mentioned four invention patent claims is that the selector contact unit and the switching device for switching without interruption can be manipulated by means of the common said motor drive, so that the motor can be realized without intermediate connection of th...
