High-pressure mainstay ceramic insulator and insulator ultrasonic-wave fault-detection standard test block

The utility model provides a high-pressure mainstay ceramic insulator and insulator ultrasonic-wave fault-detection standard test block, which consists of a test block body, and seven arc surfaces, one plane, six through holes and eight isobathic grooves, which are arranged on the test block body, wherein the middle part of the cylindrical test block body is provided with two vertical through holes, two ends are provided with two horizontal through holes, the two vertical through holes divides the test block body into a left and a right test bodies; eight isobathic grooves are respectively arranged on eight surfaces of the two test bodies, wherein the upper surface of the left test body is of a plane, three arc surfaces are respectively arranged on the left side, the right side and the bottom part of the plane of the left test body, and four arc surfaces are respectively arranged on the upper part, the bottom part, the left side and the right side of the right test body. Compared with the prior art, the test block has the advantages that the test block has better physical mechanics than that of the pure aluminum, is easy to process and resists the abrasion, and the sound velocity is 6350 m/s and is stable, the processing is convenient, and the like.
