MNS低壓抽屜柜發(fā)生儲能故障怎么辦？這個(gè)問(wèn)題是不少用戶(hù)會(huì )問(wèn)到的，為了讓大家能夠在之后的日子里順利正常的使用，下面小編為您解答下這個(gè)問(wèn)題。

What should I do if there is an energy storage failure in the MNS low-voltage drawer cabinet? This is a question that many users will ask. In order to enable you to use it smoothly and normally in the days to come, let's answer this question for you.

1.行程開(kāi)關(guān)調節不當

1. Improper adjustment of travel switch

行程開(kāi)關(guān)是控制電機儲能位置的限位開(kāi)關(guān)。當電機儲能到位時(shí)將電機電源切斷。如果限位過(guò)高時(shí)，機構儲能已滿(mǎn)。故障現象是:電機空轉不停機、儲能指示燈不亮。只有打開(kāi)控制開(kāi)關(guān)(HK)才能使電機停止。限位調節過(guò)低時(shí)，電機儲能未滿(mǎn)提前停機。由于儲能不到位開(kāi)關(guān)不能合閘。調節限位的方法是手動(dòng)慢慢儲能找到正確位置，并且緊固。

The travel switch is a limit switch that controls the energy storage position of the motor. Cut off the power supply of the motor when the energy storage of the motor is in place. If the limit is too high, the mechanism energy storage is full. The fault phenomenon is that the motor does not stop when idling and the energy storage indicator does not light up. Only by opening the control switch (HK) can the motor stop. When the limit adjustment is too low, the motor stops in advance before the energy storage is full. The switch cannot be closed because the energy storage is not in place. The way to adjust the limit is to slowly store energy manually to find the correct position and tighten it.

2.電機故障

2. Motor fault

如果電機繞組燒毀，將有異味、冒煙、保險熔斷等現象發(fā)生。如果電機兩端有電壓，電機不轉?？赡苁翘妓⒚撀浠蚰p嚴重等故障。判斷是否是電機故障的方法有測量電機兩端電壓、電阻或用其它好的電機替換進(jìn)行檢查。

If the motor winding is burnt, there will be peculiar smell, smoke, fuse blowing and other phenomena. If there is voltage at both ends of the motor, the motor will not rotate. The carbon brush may fall off or be seriously worn. The way to determine whether the motor is faulty is to measure the voltage and resistance at both ends of the motor or replace it with other good motors.

3.控制開(kāi)關(guān)故障或電路開(kāi)路

3. Control switch fault or open circuit

開(kāi)關(guān)柜認為控制開(kāi)關(guān)損壞使電路不能閉合及控制回路斷線(xiàn)造成開(kāi)路時(shí)，故障表現形式都是電機不轉、電機兩端沒(méi)有電壓。查找方法是用萬(wàn)用表測量電壓或電阻。測量電壓法是控制電路通電情況下，萬(wàn)用表調到電壓檔，如果有電壓(降壓元件除外)被測兩點(diǎn)間有開(kāi)路點(diǎn)。用測量電阻法應當注意旁路的通斷，如果有旁路并聯(lián)電路，應將被測線(xiàn)路一端斷開(kāi)。

The switch cabinet believes that when the control switch is damaged and the circuit cannot be closed and the control circuit is disconnected and causes an open circuit, the fault manifestations are that the motor does not rotate and there is no voltage at both ends of the motor. The search method is to measure the voltage or resistance with a multimeter. The voltage measurement method is to adjust the multimeter to the voltage range when the control circuit is powered on. If there is voltage (except for the step-down element), there is an open circuit between the two measured points. Pay attention to the on-off of the bypass when using the resistance measurement method. If there is a bypass parallel circuit, disconnect one end of the measured line.
