What should I do when the air conditioner encounters unstable voltage in winter?

During the peak electricity consumption period in winter, the situation of voltage instability may occur under certain circumstances. If the voltage is unstable during use, and the electrical appliance cannot withstand this voltage change, it is very likely that a short circuit or failure will occur. Take the air conditioner as an example, what should I do if the voltage is unstable?

　　So, what should we do if the voltage is unstable while using the air conditioner?

1. The compressor motor is difficult to start.

　　When the main control switch is turned to the cooling gear, pay attention to whether the compressor has been started and entered the running state. If it cannot be started, it should be shut down immediately. If it still cannot be started again, the cooling should be suspended until the voltage rises before starting to use. Do not leave without permission when the main control switch is turned to the cooling gear, because the compressor overload protector is frequently turned on and off for a long time. its burned.

　　At the moment when the air conditioner is started, because the starting current is too large, the pointer of the ammeter can hit the bottom instantaneously, and then return to the normal working current value of the air conditioner (please refer to the product manual). For example, the normal working current of an air conditioner with a cooling capacity of 3480W (3000kcal/h) is 7.5A. If the pointer of the ammeter hits the bottom at the moment of starting, and then the pointer points back to 1A, it means that the compressor is not working, and the current value of 1A is only Indicates that the wind turbine is working. At this time, the main control switch should be used to cut off the compressor circuit.

　　Second, the compressor is running unstable. Grid voltage fluctuations can cause the compressor to run extremely abnormally and sometimes stop automatically. In this case, the user should use the main control switch to cut off the compressor circuit to prevent the compressor motor wiring group from being burned.
