背景技术Background technique
断路器机械特性测试是断路器试验必做项目，试验前需要将试验接线接到断路器端口两端，35kV及以上户外敞开式断路器接线位置较高，需使用高空接线杆。原接线方式为：试验接线通过接线杆顶端接线夹固定到断路器上下接线板，外置的试验接线容易脱落，如相邻的间隔带电则有安全风险。同时试验接线较长，布线收线交繁琐，影响工作效率。The mechanical characteristic test of the circuit breaker is a must-do item in the circuit breaker test. Before the test, the test wiring needs to be connected to both ends of the circuit breaker port.
