--- 1.application range and characteristic

----- The indoor high volt charged display device is composed of three sensors and display(through lead connection),it is applied to certain indoor high volt electric equipment of rated frequency 50Hz and rated volt below 40.5KV,by this device,it could indicate charged condition in circuit,besides,it can be coordinate-operated with electromagnetic lock,which realizes forced lockout of switch handle and controlled by one high volt signal,while,its circuit system is stand-alone and not interfered one another.Just needing the high volt circuit electrified,even if display circuit and latching circuit arise fault simultaneously,the electromagnetic lock still stay in locking state,which could prevent from mishandle or entering into charged spacing.
