江蘇春晨電纜有限公司生產YFFB扁電纜，電壓低的原因大概分為以下三種抄：

The causes of low voltage can be roughly divided into the following three types:

一是可能用電負荷大幅飆升，臺區出現超負荷運行現象；

First, the power load may soar sharply, and overload operation occurs in the station area;

二是可能低壓供百電線路供電半徑過長，導致線路末端用戶電壓偏低；

Second, it is possible that the power supply radius of the low-voltage power supply line is too long, resulting in the low end user voltage;

三是變壓器容量或低壓線路線徑偏小，度已經滿足不知了村民在用電高峰時期的用電情況，導致電壓偏低。

Third, the capacity of the transformer or the diameter of the low-voltage line is too small to meet the demand of the villagers during the peak period of power consumption, resulting in the low voltage.

同時，如果電壓低會影響您的正常用電，嚴道重的話還會導致燒壞電機壓縮機。

At the same time, if the voltage is low, it will affect your normal power consumption, and if the circuit is heavy, it will also cause burning of the motor compressor.

你要想穩住220V恒定電壓，必須使用高精度穩壓器，這貨可以根據振蕩變壓器取樣繞組，經過調整振蕩頻率達到穩定電壓作用。

If you want to stabilize the constant voltage of 220V, you must use a high-precision voltage regulator, which can stabilize the voltage by adjusting the oscillation frequency according to the sampling winding of the oscillation transformer.

1.變壓器中性點偏移，導致輸出不平衡。

1. The neutral point of the transformer is shifted, resulting in unbalanced output.

2.該相線負荷太大，導致電壓降低。

2. The load of the phase line is too large, resulting in the voltage reduction.

3.電源線太小，負載加重，使電壓下降。

3. The power line is too small, the load is heavier, and the voltage drops.

所以說家中的電壓低于220V是非常正常的情況，關鍵是我們要看家中的電壓是低了多少，YFFB扁電纜是否超出電壓波動范圍的下限，如果超出了電壓波動范圍的下限，我們就需要想辦法解決了，否則可能就會影響家里電器的正常使用。

So it's very normal to say that the voltage at home is lower than 220V. The key is to see how much the voltage at home is lower and whether it is beyond the lower limit of the voltage fluctuation range. If it is beyond the lower limit of the voltage fluctuation range, we need to find a way to solve it. Otherwise, it may affect the normal use of home appliances.
