초록
In this study, the temperature increase and deviations were analyzed for double and single connections in solid wires. The influence of the temperature rise was flat based on the bolt-type and shutter-type clamping methods as well as single and double connection methods used, when the constant load current condition was applied. The temperature deviations of the single and double connections were measured as 4.3°C for the bolt-type and 1.1°C for the shutter-type methods over the approximately 40 min test. The front and side temperatures of the breaker were 69.4°C and 73.2°C for the bolt-type and 14.5°C and 10.2°C for the shutter-type clamping methods, respectively.
