Back in the seventies, sulfur hexafluoride switches and vacuum switches competition in general there have been a fierce factional great debate in the international market. Proposed vacuum switch sulfur hexafluoride send a strong X-ray will be breaking current process, a serious health hazard high voltage vacuum load switch operator and should be a total ban on use. And sulfur hexafluoride gas has excellent arc performance and insulation performance, no - kind of media or mixed media to replace it. Vacuum faction believes sulfur hexafluoride gas by breaking current of Arc burned, immediately break down into toxic gas, sulfur hexafluoride switch box in every moment from leaking into the atmosphere trace, the total leakage very impressive, especially when sulfur hexafluoride switch explode undoubtedly more serious. If widely used sulfur hexafluoride gas as a switch arc medium, atmospheric pollution is out of control. Debate on the vacuum pressure to send very large, the school conducted a number of breaking current measurement, fortunately measure X-ray radiation is much lower than the standard number of measurement specified load switch wholesale, concluded that the hazard to the operator. This great debate finally reported at the time of a paragraph. Load switch use and maintenance: 1 After unpacking the packing list and randomly check the product technical documentation are complete, check the product for damage during transportation, storage process. 2 Remove dust on the product, and insulators and grounding parts wipe clean. 3 conductive parts and mechanical friction parts, coated with neutral Vaseline. 4 After installation is complete check the wiring is correct, good grounding is reliable. 5 in operation should be regular inspection and maintenance load switch factory outlets, once a year; in breaking 20 times the rated load, it should conduct a comprehensive overhaul. 6 Inspection should not charged in the case, and should check the insulator, the contact exposure and so on. 7 operating personnel must be familiar with all parts of the performance, configuration and installation of the load switch.
