Power fluctuation: entire plant shut down
Thread Content
A synthetic 10kV pump failure caused a power surge throughout the plant, leading to shutdowns; the liquid oxygen pump also stopped operating due to the power surge. As for why no measures were taken at the substation in advance, there are rumors that everyone was busy studying for the safety compliance exam; haha. It just happened to be the company-wide safety **compliance exam. What should we all pay attention to regarding HFPS? Let’s talk about it
What does \"flashing voltage\" mean? Is it a drop in voltage? Then you should also have voltage compensation, right?
Our office has also experienced power fluctuations recently; could you help analyze what might be causing them as well? Another strange phenomenon is that voltage fluctuations can cause interference with our DCS system when the equipment is restarted, and this interference can even lead to a network outage. The pump that trips due to voltage fluctuations shares the same power grid segment as our DCS UPS.
Power fluctuations aren’t that scary. Some time ago, our factory’s UPS system failed, and all the control computers stopped working – that was really a disaster. There are many emergency situations that are impossible to predict, and it’s important to remain calm and know how to respond in such critical moments
We’ve encountered that too; the whole factory became chaotic all of a sudden. Hot water at over 100 degrees was sprayed out directly, but fortunately no one was injured. Safety first. Therefore, the UPS must be stable and reliable; an is a type of UPS suitable for use in chemical plants. Under no circumstances should one save money at the expense of this; a minor loss might be acceptable, but in worse cases it could lead to casualties and significant losses. We have experienced such things. It’s really impressive.
Frequent opening and closing of the contacts in the high-voltage cabinet causes shaking.
This problem can be resolved by using \"special devices for dealing with voltage fluctuations,\" which can operate in an automatic mode. Based on the controlled device, these solutions can be categorized into those for controlling AC contactors, circuit breakers, frequency converters, and soft starters; whereas based on the control voltage level, they can be divided into low-voltage and high-voltage controls. With this solution, one control cabinet can manage as many as dozens of motors. It is cost-effective and efficient, enabling production to resume in as little as 0.1 seconds. Moreover, it features numerous safety measures; however, some systems that do not use release contacts can cause the contacts to burn or stick together, leading to the tripping of the main power switch and resulting in serious accidents ； Many users adopt this solution, which is designed specifically to address issues such as voltage fluctuations (caused by external power supply problems or internal grounding faults). It has over a decade of experience in being used in China; it offers excellent performance, high cost-effectiveness, and high reliability, to the point that users have never even needed to purchase spare parts for it ； It can be considered. For users with few devices, there is a single controller. Given the price issue, it’s best for you to contact the manufacturer directly! If you can get in touch, I’m sure it will satisfy you.
