微動(dòng)開(kāi)關(guān)常見(jiàn)故障解析及應(yīng)用
發(fā)布時(shí)間：2019-10-29 瀏覽次數(shù)：85 返回列表| 微動(dòng)開(kāi)關(guān)應(yīng)用 | | 沖擊與振動(dòng) Shock and Vibration | 如果微動(dòng)開(kāi)關(guān)用在需經(jīng)受沖擊和振動(dòng)的場(chǎng)合, 選擇大操作力的開(kāi)關(guān), 能夠改善抗沖擊和振動(dòng)性能.如果有可能,將驅(qū)動(dòng)桿運(yùn)動(dòng)方向與沖擊或振動(dòng)加速度方向成90度角. 另外要選擇過(guò)行程盡可能大的微動(dòng)開(kāi)關(guān) If switches are likely to be subjected to shock or vibration, select models with the highest avail able actuating force. If possible, the switches should be mounted so that the line of acceleration is at right angles to the travel of the plunger. The maximum avail able overtravel should be used. | 直流負(fù)載 Direct Current | 在直流負(fù)載情況下, 不要使用超過(guò)指定值的電流, 以避免產(chǎn)生破壞性電弧,導(dǎo)致觸點(diǎn)熔化或霧化. 在一些感性直流回路中要增加消弧抑制措施, 與開(kāi)關(guān)和電源串聯(lián)在一起（或需要開(kāi)關(guān)觸點(diǎn)間距增大）. Direct current (DC) ratings where shown should not be exceeded if destructive arcing and contact welding are to be avoided. Some form of arc suppression is recommended when switches are used in DC circuits containing inductive devices wired in series with the switch and the supply. | 燈泡負(fù)載 Lamp Loads | 由于白熾燈都帶有很高的浪涌電流, 因此應(yīng)用要具體分析. Because of the very high inrush currents associated with incandescent lamps, applications should be subject to individual assessment. | 容性負(fù)載(包括日光燈) Capacitive Loads (including fluorescent lamps) | 容性負(fù)載會(huì)產(chǎn)生很高的尖峰電流,導(dǎo)致觸點(diǎn)熔化, 因此具體應(yīng)用需具體分析. These can generate very high peak currents which can cause contact welding. Applications should be subject to individual assessment. | 感性負(fù)載 Inductive Loads | 感性負(fù)載,伴隨變化的電壓,比如帶一個(gè)電機(jī), 可能會(huì)產(chǎn)生6倍正常工作電流的浪涌電流.對(duì)于特定的開(kāi)關(guān), 一般采用L/R = 5ms(直流) 和cos∮（功率因數(shù)）= 0.75-0.8(交流)來(lái)描述開(kāi)關(guān)的性能（UL1054標(biāo)準(zhǔn)）cos∮=0.6-0.65（國(guó)標(biāo)）. an inductive circuit, with alternating voltage, for example, incorporation a motor(cos∮<1) can cause current surges up to 6 times the nominal current. For certain switches, we give electrical edurance curves with L/R = 5ms in DC and cos∮= 0.8 in AC. |
