Background: The production line of a certain electronic component processing plant is frequently affected by the start-up/shutdown of high-power equipment in surrounding factories, resulting in frequent fluctuations in the power grid voltage (as low as 180V and as high as 250V), causing precision equipment such as surface mount machines and welding machines to frequently report errors and shut down, affecting production for 2 hours per day and increasing the defect rate by 5%.
Solution: Install Zhongzhe industrial grade voltage protectors at the front end of the production line's main distribution box and key equipment, with a wide protection range (160V-260V) and three-phase voltage imbalance protection function; When the voltage is abnormal, the corresponding circuit will be cut off within 0.1 seconds, and an alarm message will be sent to the central control room through the IoT module.
Effect: The number of equipment shutdowns has decreased from 8 per day to 0 per day, the defect rate has returned to normal levels, the daily production has increased by 3000 pieces, and the annual loss recovery is about 70000 USD.
