Jul. 10, 2019

What is the cause of poor current contact in the Power Distribution Cabinet? Several circuit breakers that connect to the server device trip, not during the day, and not every night, why? We give you the following suggestions.


Power Distribution Cabinet

Power Distribution Cabinet


1. First check the power equipment under the power distribution cabinet (distribution cabinet, box substation, distribution box) to see if there is a high power output during the accident period.

2. Check the wiring connection inside the power distribution cabinet (distribution cabinet, box substation, distribution box) and to the electrical equipment to see if there is a virtual connection.

3. Investigate whether there is a human factor causing a short circuit during the accident.

4. Check whether the electrical equipment (distribution cabinet, box substation, distribution box) is damaged. (The power is low at 12 o'clock to 2 o'clock in the evening. The line voltage is relatively high. If the equipment itself is damaged. Edges, such as diodes, may cause a transient breakdown when the voltage reaches a certain level, causing a short circuit.) Under normal circumstances, if there is no problem with the design, there will be no such situation. Personally think that there is a high possibility of a virtual connection, you better check the line.
