Do you know what to pay attention to when using UPS uninterruptible power supply? Now I would like to share with you the matters needing attention in the use of UPS uninterruptible power supply:
▲Lightning protection grounding of the three-phase UPS power supply
Lightning strike is the natural enemy of all electrical appliances. Pay attention to the screen-cover and grounding protection of the three-phase UPS power supply.To prevent parasitic capacitive coupling interference and protect the device and human body, ground the UPS with a ground resistance greater than or equal to 1 ohm.
▲Three-phase UPS operating environment
Industrial UPS power supply host is not high on the environmental temperature requirements, working environment temperature requirements of 0℃ - 40℃, humidity of 10% - 90%. Keep the UPS out of direct sunlight and have enough space for ventilation. Keep the UPS working environment clean to prevent corrosive dust from internal components. Otherwise, dust and moisture may cause abnormal operation of the UPS.
Three-phase UPS power distribution box used by unfavorable choose old-fashioned breaker switch, and should adopt air switch, because in the old switch on or cut off power supply when arc phenomenon, while air switch with arc suppression and load short circuit when the function of fast response, and leakage protection and overheating protection function on the grid. In addition, do not use the fuse type fuse, because the overcurrent response speed is slow, when the load or UPS short circuit cannot be cut off in time, which will cause harm to the device.
The fluctuation range of mains voltage must comply with the UPS input voltage variation range. If the mains voltage fluctuation is large, it is necessary to increase its other protection measures (such as three-phase voltage regulator, etc.) in the UPS front stage. Ac voltage regulator can be used as the UPS input stage.
When using the UPS, comply with the product specifications of the manufacturer of the three-phase UPS power supply. Ensure that the phase, neutral, and ground cables connected to the UPS meet the requirements. Do not change the sequence of the phase, neutral, and ground cables.
