When wireless phasing tester nuclear phase, it can not ensure that phasing tester metal part keeps enough electricity with trolley divider metal part
It is split to there is nuclear phase lever in the nuclear phase work of 10 kilovolts of trolley type switchs at present for gas safe distance or creeping discharge distance
Steel plate electric discharge in cabinet is closed, making the person, equipment that cannot be ensured in safety causes staff's personal safety accident to occur.
In separated dodge gate baffle, the body of operating personnel may probe into cabinet, with 10kV electrical bodies safety away from
From deficiency, it can not ensure the personal safety of staff, there are security risks, also, overhead gage presence falls risk.Wireless
During nuclear phase instrument transmitter contact buses side (upside) static contact, however not excluded that overhead gage machinery positioner failure, gravity factor
It falls.
