为确保“三夏”大忙季节安全用电,解决好麦场临时接线是“三夏”安全用电的重要环节。 一、据以往在“三夏”安全用电检查中发现,有不少村电工在麦场临时接线不符合安全用电标准和要求,即下线在电源线上绕2—3圈,虽不是挂钩接线,却存在导线接触不牢,导电不良,遇大风下线与电源线易产生接触点轴向或径向移动,导致接线点打火,用电设备发热,缩短使用寿命,甚至烧坏电机等事故。 为此,村电工应严格按照电工安全操作规程作业,并建议生产厂家生产一种有可靠的绝缘、足够的压力和接触面及导电性好的“线夹”。临时接线用专用“线夹”直接夹在电源线上,使“线夹”牢牢衔咬住电源线,可增大下线与电源的接触面和压力,若遇大风也可避免接线点松动打火现象,从而改善导电性能。 二、对用电户数多,麦场集中的地点,设公用电源配电装置,按各农户总用电容量配置电力线、电能表、闸刀和保险丝。严禁铝、铁丝代替保险丝和超负荷运行。并在 To ensure “three summer” busy seasonal electricity, solve the temporary wiring wheat field is “three summer” an important part of the safe use of electricity. First, according to the past in the “three summer” safety electricity inspection found that there are many village electrician temporary wiring in the wheat field does not meet the safety standards and requirements of electricity, that is offline in the power line around 2-3 laps, though not Linked to the wiring, but there is a poor wire contact, poor conductivity, in case of gale and the power cord easy to produce contact point axial or radial movement, resulting in wiring ignition, heating power equipment, shorten the service life, and even burn the motor Other accidents. To this end, the village electrician should be strictly in accordance with electrical safety practices operating procedures, and manufacturers recommend a reliable insulation, adequate pressure and contact surface and good conductivity “clamp.” Temporary wiring with a dedicated “clip” clip directly on the power line, so that “clip” firmly capitated the power cord can increase under the line and the power of the contact surface and pressure, in case of strong winds to avoid loosening of the wiring Spark phenomenon, thereby improving the conductivity. Second, the number of households with electricity, wheat field concentration of locations, set the public power distribution device, according to the total capacity of the allocation of rural households power lines, watt-hour meters, guns and fuses. Aluminum, wire instead of fuses and overload operation is strictly prohibited. And at
