MNS低壓抽屜柜發(fā)生儲能故障怎么辦？這個問題是不少用戶會問到的，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問題。

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.行程開關(guān)調(diào)節(jié)不當

1. Improper adjustment of travel switch

行程開關(guān)是控制電機儲能位置的限位開關(guān)。當電機儲能到位時將電機電源切斷。如果限位過高時，機構(gòu)儲能已滿。故障現(xiàn)象是:電機空轉(zhuǎn)不停機、儲能指示燈不亮。只有打開控制開關(guān)(HK)才能使電機停止。限位調(diào)節(jié)過低時，電機儲能未滿提前停機。由于儲能不到位開關(guān)不能合閘。調(diào)節(jié)限位的方法是手動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(xiàn)象發(fā)生。如果電機兩端有電壓，電機不轉(zhuǎn)。可能是碳刷脫落或磨損嚴重等故障。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.控制開關(guān)故障或電路開路

3. Control switch fault or open circuit

開關(guān)柜認為控制開關(guān)損壞使電路不能閉合及控制回路斷線造成開路時，故障表現(xiàn)形式都是電機不轉(zhuǎn)、電機兩端沒有電壓。查找方法是用萬用表測量電壓或電阻。測量電壓法是控制電路通電情況下，萬用表調(diào)到電壓檔，如果有電壓(降壓元件除外)被測兩點間有開路點。用測量電阻法應(yīng)當注意旁路的通斷，如果有旁路并聯(lián)電路，應(yīng)將被測線路一端斷開。

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.
