Cooling System for HV Switching Personnel in Arc Flash Suit
Abstract
High Voltage switching is very dangerous and has caused many fatalities or damage to equipment. Two of the most common sources of HV switchgear accidents are a lack of following safety protocols and an insufficient understanding of the HV electrical systems; just as car drivers can avoid accidents with proper understanding of driving, so can HV personnel. But because HV switching accidents do happen, Switching Personnel are required to wear Arc Flash suits. But the experience of Switching Personnel in equatorial Malaysia is that they sweat profusely even after a minute of wearing such a suit. The reason is because these suits are designed and manufactured in temperate countries where warm armor like this will be welcomed. To solve this, in this research an air conditioning system was built to enable blowing cool air within the Arc Flash suits via a pipe going up from the bottom of the suit to the chest level. The robust car air conditioner system was driven by a 2 HP motor and a long flexible pipe will enable the switching personnel to reach many HV switchgears. One such system should be permanently placed in each substation.
