Background: During road maintenance, a certain outdoor construction team uses alternating power supply between generators and mains electricity. During the switching process, voltage surges or phase deviations often occur, causing damage to cutting machines, welding machines, and other tools, and even posing a risk of electric shock; Moreover, the outdoor environment is humid, and ordinary protective devices are prone to misoperation.
Solution: Adopting outdoor voltage protectors with Zhongzhe waterproof rating of IP65, equipped with surge resistance and phase detection functions, supporting automatic switching protection between generator and mains power. When abnormal voltage or phase error is detected, the output is immediately disconnected and construction personnel are alerted through sound and light alarms; The protector shell is made of anti drop material, suitable for complex outdoor environments.
Effect: No damage to tools due to voltage issues occurred during the construction period, eliminating the risk of electric shock, improving construction efficiency by 20%, and reducing tool maintenance costs by approximately $3000 per month.
