Abstract

Abstract:

Aiming at the problem that the transmission and distribution lines are electrically connected to the hair heat and cause energy loss, the application performance of low melting point alloys in electrical connectors was studied. Low-melting alloys Sn-3.5Ag, Sn-1.6Cu, and Sn-Zn-0.7Cu with good wettability at the copper interface were selected and a joining process in the electrical connection was designed and constructed. The reliability of the interface after connection was judged by using the ERESCO MF4 portable X-ray machine. The SLQ-2000A up-flow experimental system was established and the actual working conditions were simulated. Finally, the low-melting alloy and electric composite grease samples were tested for the heat generation of the test piece during the continuous flow time of 4 hours at a rated flow rate of 180 A. The experimental results showed that the calorific value of the low melting point alloy as the electrical connection joint material is lower than the calorific value of the electric composite grease joint sample.

Key words: electrical connector, low melting point alloy, electric composite grease, thermal stability, contact surfaces, calorific value
