Abstract
The invention relates to a sensor bracket for testing working deformation vibration of an ultrahigh-voltage transformer. The sensor bracket comprises the components of a multi-joint rod which is arranged in a vertical direction, an array bracket which is arranged at top of the multi-joint rod, and a sensor slide rail positioning system which is arranged on the array bracket. The sensor slide rail positioning system comprises a slide rail which is arranged on the array bracket, and a plurality of sensor clamping mechanisms which are arranged on the slide rail and can move along the slide rail. The plurality of sensor clamping mechanisms simultaneously arrange a plurality of sensors on the surface of the ultrahigh-voltage transformer. Compared with prior art, the sensor bracket is advantageous in that a human is isolated from the transformer through designing the sensor bracket, thereby effectively preventing a safety problem generated in manual sensor mounting in testing working deformation of the ultrahigh-voltage transformer so that the sensor can be mounted safely on the condition that the transformer is electrified; and furthermore high-efficiency and high-precision mounting and recycling of the sensor can be realized.
