一种10 kV开关挡板安全锁的研究

A Novel Safety Lock for 10 kV Switch Baffle

在10 kV开关检修工作中,开关本体被拉至“检修”位置时,开关柜断路器的静触头挡板处于活动状态,使用传统的挂锁来锁定开关柜断路器静触头挡板,操作繁琐,误操作的可能性大,触电的风险高。为此研制了一种10 kV开关挡板安全锁,其结构简单、制造成本低,操作方便、省力,通用性高,可规避误触电风险,安全可靠,同时还可以防止未取锁误将开关本体推入柜内,损坏开关的风险。

In the overhaul of 10 kV switch,the static contact baffle of the circuit breaker in the switch cabinet is free to move when the switch body is pulled to the“overhaul”position.Usually,ordinary padlocks are used to lock the baffle,which is of cumbersome operation,high mis-operation possibility and high risk of electric shock.A novel safety lock is designed for the 10 kV switch baffle,which has advantages of simple structure,low manufacturing cost,convenient operation,manpower saving,high versatility,low risk of electric shock,and high safety and reliability.Also,it can prevent the risk of damaging the switch by pushing the switch body into the cabinet without taking the locks.
