Correct use of high voltage isolating switch-2

(7) The relevant regulations shall be followed when opening and closing the knife switch with load and no-load current.
(8) For the operation of high voltage isolator with remote control operation function, it shall generally be operated in the main control room. Only when the remote control electrical operation fails, can it be operated on site by electric or manual operation high voltage isolator switch with the permission of the director and the technical person in charge and under on-site supervision.
(9) After the remote control operation is completed, the actual position of hv isolator shall be checked to avoid the phenomenon of refusal to open or close due to the failure of the transmission mechanism in the control circuit. At the same time, the contact of hv isolator switch shall be checked to see if it is in place.
(10) When the insulator of high voltage electrical isolator is found to be broken, the corresponding circuit breaker shall be opened according to the regulations.
(11) Safety helmets, insulating gloves and insulating boots shall be worn during operation.
(12) After operating isolator high voltage, the anti-misoperation locking device shall be locked to prevent misoperation next time.
