Description

Technical Field

[0001] The utility model relates to the technical field of impulse voltage generators, in particular to an impulse voltage generator support mechanism. Background Art

[0002] An impulse voltage generator is a high-voltage generating device used to generate pulse waves such as lightning impulse voltage waves and switching overvoltage waves. It is a basic test equipment in high-voltage test laboratories and is widely used in power systems, power equipment, electronic equipment and other fields.

[0003] A Chinese utility model patent with publication number CN218954375U discloses a support mechanism for an impulse voltage generator. The mechanism mainly includes a base, an impulse voltage generator body mounted on the base, and support plates and screws and other components are respectively provided on the four peripheries of the base. The screws are rotated to drive the stabilizing support plates and elastic pressure blocks downward, pressing them against the ground to prevent them from tipping over.

[0004] However, during use, since the peripheral supporting components are all vertically downward, after the stabilizing support plate and the elastic pressure block move downward, the entire device still forms a rectangular column from top to bottom. However, the overall height of the device is often high and the center of gravity is relatively high. Although the feet are supported by the contact with the ground through the supporting components, the supporting surface formed by the vertically downward supporting components is small, and it is very easy to tip over when subjected to lateral force, thereby causing damage to the generator.
