When the high and low voltage switch cabinets have excessive current, check their wiring problems.
If daily high and low voltage switch cabinets and high and low voltage distribution cabinets are used, there will be a phenomenon that the current is too large and the internal circuit breaker of the machine will trip, and it will only occur after a period of time. What is the specific reason? The following editors of high and low voltage switchgear manufacturers will answer your questions.
1. First, you should check whether the power distribution facilities under the power distribution cabinet have high power output in the time period of the accident.
2, check the wiring connection in the high and low voltage switchgear in the power distribution cabinet for the wrong connection and missing connection phenomenon, if there is such a phenomenon can be corrected
3. Investigate the maintenance records of employees to check whether the line was shorted due to human error during the accident.
4. Check whether the electrical equipment is damaged and high-power operation cannot adjust the current and voltage in time. You should check with the manufacturer to ensure the normal operation of the high and low voltage switchgear.
Once there is a phenomenon of excessive current or excessive power, it is necessary to thoroughly check the entire high and low voltage switch cabinet for any line or component problems, which can reduce the occurrence of dangerous accidents.
