A, electrical safety accident prevention management work mainly includes:
1, the installation of electrical to meet the insulation and isolation requirements, the removal of electrical equipment to be thoroughly clean. The metal shell of the electrical equipment must be effectively grounded. Electrical operators should properly use insulated gloves shoes, pads, clamps, rods and tester pens and other safety tools.
2, strengthen the whole staff of the prevention of electric shock accident education, improve the awareness of the whole staff of the prevention of electric shock; improve the safety of electricity system; strictly prohibit unlicensed personnel engaged in electrical work; the use of electrical equipment should be strictly enforce the safety regulations.
Two, the requirements: protective grounding is the fault situation may present a dangerous voltage to ground the conductive part of the earth with the earth closely connected. As long as the proper control of the protective grounding resistance size, you can limit the leakage of equipment to the ground voltage in the safe range. Where insulation damage or other reasons may present dangerous voltage metal parts, unless otherwise specified, should be grounded.
Protection zero is the electrical equipment under normal circumstances, non-electrified metal parts of the power grid and the protective zero line interconnection. This safety technology measures for neutral point directly grounded, the voltage of 380 volts / 220 volts of three-phase four-wire power distribution system. Protection of the basic role of zero is when a phase of the charged part of the equipment shell touching, through the equipment shell to form a single relative to the zero line of the relative short-circuit, short-circuit current prompted by the line on the overcurrent protection device to act quickly, the fault part of the disconnecting current? Eliminate the risk of electric shock.
Third, it is recommended that: for the occurrence of electrocution accident peak value with seasonal features to do a good job of prevention.
