Abstract
The invention relates to a high-power ultrasonic detection device for a basin-type insulator of a substation combined electrical appliance in the field of power equipment detection. A block-shaped main body is formed by mixing epoxy resin and aluminum powder and then carrying out vacuum casting, the main body is in a step shape, the width of each step is 35-45 mm, the length of each step is 90-110mm, a plurality of recesses are formed in the upper surface of each step, and the distance between every two adjacent recesses is 8-12 mm. According to the detection device, high-power ultrasonic detection is carried out on the sensitivity of the basin-type insulator by adopting a high-power ultrasonic sensitivity test block, and the defects in the manufacturing process are discovered in time through the operation of the high-power ultrasonic sensitivity detection, so that the aims of promoting the targeted improvement of the production process and correspondingly improving the safety performance of the product are achieved.
Description
【Technical field】 [0001] The invention relates to the field of electric equipment detection, in particular to a device capable of implementing high-power ultrasonic detection sensitivity for basin-type insulators of substation combined electrical appliances. 【Background technique】 [0002] As we all know, in the power industry, GIS refers to sulfur hexafluoride closed combined electrical appliances, which is called "metal insulated metal closed switch" internationally, and its components are mainly composed of central conductors, operating parts, shells, and pot insulators. These components are all enclosed in a metal grounded shell, which is filled with sulfur hexafluoride gas insulating gas; at present, the pot insulators in GIS are all made of composite materials, which are mechanically mixed and stirred by epoxy resin and alumina powder , and then vacuum casting in a metal mold, and after secondary curing, the alumina particles finally form an "island" structure in the e...
