Abstract

The invention discloses a testing clamp for a model winding bar used for studying reactor turn-to-turn insulation vibrating and aging. The testing clamp comprises an upper pressing plate, a lower pressing plate fixed to a vibrating testing table and connected with the upper pressing plate through a first connecting piece, and a model winding bar clamp plate module arranged between the upper pressing plate and the lower pressing plate. A model winding bar clamp plate comprises a left pressing plate, a first clamp plate, a second clamp plate, a third clamp plate and a right pressing plate, wherein a groove matched with model winding bars in appearance is formed in one face of the first clamp plate, grooves matched with the model winding bars in appearance are formed in the both sides of the second clamp plate, a groove matched with the model winding bars in appearance is formed in one face of the third clamp plate, and a semi-circular groove is formed in the other face of the third clamp plate. The left pressing plate, the first clamp plate, the second clamp plate, the third clamp plate and the right pressing plate are fixedly connected through a second connecting piece so that the model winding bar can be clamped by the two adjacent clamp plates. Vibrating and aging of the multiple model winding bars are tested, the insulating and aging situation can be learned, testing time is saved, and reliability of test data is improved.

Description

technical field [0001] The invention relates to the field of test fixtures. More specifically, the present invention relates to a test fixture for a model bar used to study the vibration aging of the inter-turn wrapping insulation of a dry-type air-core reactor. Background technique [0002] In the design standards of ultra-high voltage and large power grid substations, a certain number of reactors are required to be connected in series or in parallel to adjust the reactive power of the grid, so as to enhance the stability of the power system, improve the quality of power transmission, and reduce line losses. The reliability of the reactor is related to the safe operation of the power grid. Once it fails, it will bring immeasurable direct or indirect economic losses to the power system and society. At present, dry-type air-core reactors have been rapidly developed and widely used due to their advantages such as simple structure, good linearity, no noise, and maintenance-fre...
