Cause Analysis and Solutions About Abnormal Heating of Equipment Clamp

As a kind of link terminal in power grid system, clamp has become one of the key components and widely used for connecting the transmission lines and electrical equipment. However, the joint between the tubular structure and the terminal plate or the drainage plate is always a weak part, which is easy to produce defects and then accelerate the failure of the clamp during service. This is also limited the use space of clamp to a certain extent. In this paper, research status on heating causes of equipment clamps and the corresponding solutions are mainly summarized. And the application of disc shape memory alloy gasket as well as the design of mortise tenon structure clamp will fundamentally solve the problem of abnormal heating of wire clamp.
