There are several possible reasons for the sudden power outage of the butyl adhesive coating machine for insulating glass:

1. 電源故障：檢查一下是否有電源線松動或者插頭接觸不良，也可以嘗試將插頭接到其他正常的電源上進行測試。

1. Power failure: Check if there is any loose power cord or poor plug contact, or try connecting the plug to another normal power source for testing.

2. 斷路器跳閘：檢查一下斷路器是否跳閘，如果是，請重置斷路器。

2. Circuit breaker tripping: Check if the circuit breaker has tripped, and if so, reset the circuit breaker.

3. 過載保護：如果使用過程中負荷過大，可能會觸發過載保護，導致機器斷電。在使用機器時，請確保不要超過其額定功率。

3. Overload protection: If the load is too high during use, it may trigger overload protection and cause the machine to power off. When using the machine, make sure not to exceed its rated power.

4. 故障電路：如果以上情況都排除了，可能是機器內部出現故障電路。這時候好請的維修人員進行檢修，避免自行修理造成更大的損壞。

4. Fault circuit: If all the above conditions are eliminated, it may be a faulty circuit inside the machine. It is best to hire professional maintenance personnel for maintenance at this time to avoid self repair causing greater damage.

總之，如果中空玻璃丁基膠涂布機突然斷電，建議先檢查電源、斷路器和負荷情況，如未問題，好求助于的維修人員進行修理。

In short, if the butyl adhesive coating machine for insulating glass suddenly loses power, it is recommended to check the power supply, circuit breaker, and load condition first. If the problem is not solved, it is best to seek professional maintenance personnel for repair.
