农村常有人把灯泡安装在锅灶上方,结果功率不小,灯却不怎么明,原因何在?你如果用测电笔测量锅灶上方的灯头、花线、吊线盒。会发现氖管亮度较强。因灯具在锅灶上,受到各种气体分子的腐蚀,使灯具上布满油泥,灯具绝缘下降,造成漏电。同时各线头接头氧化锈蚀、增大电阻,消耗有功功率。使灯泡得不到额定电压,变暗甚至不亮。因此灯泡不宜安装在锅灶上方。
People often install the bulb above the cooktop in the rural area, the result is not small, but the light is not very clear. Why? If you use a stylus to measure the lamp holder, the flower wire and the hanging box at the top of the cooker. Will find neon tube brightness is stronger. Due to the lamps on the stove, by a variety of gas molecules of corrosion, the lamp covered with sludge, lamp insulation decreased, resulting in leakage. At the same time the thread connector oxidation corrosion, increase resistance, active power consumption. So that the lamp can not get the rated voltage, dark or not bright. Therefore, the bulb should not be installed above the stove.
