Embodiment Construction
[0028] Such as figure 1As shown, the device for testing the icing or coating bonding strength of this embodiment includes a plug 2 and a plug support device 1 with a through hole in the center, and the plug 2 can be inserted into the through hole of the plug support device 1, wherein The insertion part 11 of the plug 2 is a cone, and the corresponding section of the through hole of the plug supporting device 1 matched with the cone of the plug 2 is a conical hole, and the matching of the cone and the conical hole The roughness of the surface is not greater than 0.8 microns. During the tensile test, the smooth surface of the cone and the conical hole can reduce the influence of contact friction. The length of the cone is less than the depth of the through hole of the plugging support device 1, and the top of the plugged cone is detachably connected with a covering matrix 3, and the cross-sectional area of the covering matrix 3 is suitable for The clogged cone is withdrawn fr...

Abstract
The invention provides a device for testing ice-coating or coating bond strength, comprising a blockage (2) and a blockage supporting device (1) with a through-hole in the center, wherein the blockage (2) can be inserted into the through-hole of the blockage supporting device (1), wherein the insertion part (11) of the blockage (2) fits with the through-hole of the blockage supporting device (1) and the length of the insertion part (11) is less than the depth of the through-hole of the blockage supporting device (1), and a coating substrate (3) is detachably connected with the top of the insertion part (11) of the blockage, and the coating substrate (3) is the substrate contacting with the ice-coating or with coating surface with a sectional area suitable for being drawn out from the through-hole along with the insertion part (11) of the blockage. The device only needs one blockage to test the bond strength between all the materials with wide application range and low production cost.
Description
technical field [0001] The invention relates to a test device and method for testing the bonding strength between various materials. In particular, it relates to a test device and method for testing the bond strength between ice coating and metal material or paint. Background technique [0002] In winter, due to the low temperature and high humidity, the conductors are prone to be covered with ice; as the temperature decreases and the low temperature time prolongs, the thickness of the ice coating becomes larger and larger, and the weight load brought to the high-voltage conductors increases. When the total weight of the ice coating exceeds the strength limit of the conductor, it will cause serious consequences such as cable breakage and the collapse of the tower. In addition, after the ice coating occurs on the power transmission equipment, the insulation level will be greatly reduced, and many equipment will be damaged. "Ice flash" discharge phenomenon, a large number of ...
