Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a three-phase linkage device. Background Art

[0002] A single-phase voltage transformer is an electrical device used to measure voltage. It can convert high voltage signals into low voltage signals for easy measurement and monitoring. In power systems, single-phase voltage transformers are widely used in power measurement, protection and control.

[0003] Since the voltage transformer on the line generally requires the installation of an isolating switch, the single-phase voltage transformer has gradually begun to be equipped with a manual isolating mechanism. Its built-in isolating switch performance makes the use of combined electrical appliances more flexible, and it has been gradually used in the power grid system.

[0004] The three-phase linkage device includes a three-phase switch, and the three-phase switches realize the synchronization of switch actions through a transmission connecting rod. Specifically, the transmission connecting rod rotates under the drive of the driving rod, and the crank arms of the three-phase switch are hinged on the transmission connecting rod. When the transmission connecting rod moves, the three crank arms are driven to move synchronously;

[0005] However, when producing three-phase linkage devices, manufacturers usually produce drive rods according to the dimensions provided by customers, resulting in fixed dimensions of the drive rods. During actual installation and use, once the installation position of a single voltage transformer changes slightly due to different installation environments, the drive rods will not be able to be used normally, which is not practical enough and causes the three-phase linkage device to be unable to be installed, reducing the user experience. Therefore, we propose a three-phase linkage device. Utility Model Content
