Abstract

The invention relates to a high-voltage switch contact finger mechanical life test device. The high-voltage switch contact finger mechanical life test device comprises a movable support and a fixed support. The fixed support is provided with a static contact installation part. A moving contact installation part is arranged on the movable support; the movable support can move relative to the fixedsupport so that the moving contact and the static contact are enabled to be relatively closed or disconnected. An adjusting mechanism is arranged on the movable support and / or the fixed support; the adjusting mechanism is used for adjusting the relative angle and / or the relative radial position between the moving contact installation part and the static contact installation part so as to adjust the assembly error between the moving contact and the static contact. According to the invention, the closing and opening processes between the moving contact and the static contact of the high-voltageswitch can be completely simulated, the assembly error of the moving contact relative to the static contact in the actual assembly process can be simulated, and the actual wear condition can be satisfied.

Description

technical field [0001] The invention relates to a high-voltage switch contact finger mechanical life test device. Background technique [0002] The switch contact finger is one of the key components of the high-voltage switch, which is mainly used for the energized contact between two relatively moving conductors. The characteristics of the contacts directly affect the function realization of the high voltage switch. The key characteristics of switch contacts mainly include: contact resistance, structural stress, surface wear, etc. Studying the changes of these characteristics through experiments has very important guiding significance for the optimal design of contacts. At present, the industry's requirements for the mechanical life of high-voltage switches have been increasing year by year, and the number of opening and closing times has increased to more than 10,000. During the mechanical life test, the moving contact and the static contact constantly collide and rub. ...
