Outdoor Portable Ups Power Supply System Use And Maintenance Precautions

Outdoor portable UPS power supply in daily life emergency, plays a very important role, through the use of portable UPS power supply, can take into account the continuous provision of power supply, bring lighting for outdoor work, to ensure the normal operation of the work and carry out. The following is a compilation of some of the portable UPS uninterruptible power supply system, the correct operation can extend the service life of the system as well as improve work efficiency.

Outdoor portable UPS power supply system use precautions:

(1) outdoor portable UPS power supply system does not require high ambient temperature, +5 ℃ ~ 40 ℃ can work normally, but requires indoor clean, less dust, otherwise dust plus humidity will cause the host work chaos. Storage batteries, on the other hand, have higher temperature requirements, the standard operating temperature of 25 ℃, usually can not exceed +15 ℃ ~ +30 ℃. Temperature is too low, will make the storage battery capacity decline, the temperature of each 1 ℃, its capacity decreased by 1%. Its discharge capacity will increase with the temperature, but the life expectancy is reduced. If it is used for a long time under high temperature, the battery life will be reduced by about half for every 10℃ higher temperature.

(2) Portable UPS power supply host has many high-voltage energy storage devices, do not take apart the chassis to check. The operator must know the basic knowledge of electricians and familiar with the instruction manual.

(3) In the absence of external power supply by the portable UPS power supply system, should avoid starting the UPS power supply with a load, should first shut down the load, and then open the load after the UPS power supply system starts. Because the load instantaneous power supply will have an impact battery, the impact current of multiple loads and plus the required power supply current will cause instantaneous overload of the portable UPS power supply, and in severe cases will damage the converter.

(4) outdoor portable UPS power supply system according to the use of the required power margin is not large, in use to avoid arbitrarily increase the high power of additional equipment, but also does not allow long-term operation under full load. But the nature of the work determines the UPS power supply system is almost uninterrupted operation, increase high-power loads, even in the basic full-loaded state of work, will cause the host to malfunction, and in serious cases will damage the converter.

5) The output voltage of the self-provided generator, waveform, frequency, amplitude should be full of outdoor portable UPS power supply on the input voltage requirements, the generator's power should be much greater than the rated power of the UPS power supply, otherwise any one of the conditions is not satisfied, will cause the UPS power supply work abnormally or damaged.

(6) Whether in the float charging state or in the charging, discharging maintenance test state, to ensure that the voltage and current meet the specified requirements. Excessive voltage or current may cause thermal runaway or water loss of the battery, voltage, current is too small will cause battery loss, which will affect the service life of the UPS battery, the former has a greater impact.

(7) In any case, the battery should be prevented from short-circuiting or deep discharge, because the cycle life of the battery is related to the depth of discharge. The deeper the depth of discharge, the shorter the cycle life. In the capacity test or discharge maintenance, usually discharging to 30% to 50% of the capacity is enough.

Portable UPS power system maintenance what need to pay attention to?

It is necessary to carry out maintenance once a year, and before the maintenance should be fully prepared. For example, a variety of tools, a variety of measuring instruments, and a variety of difficulties that may be encountered. There are corresponding countermeasures, programs and measures for the problems encountered.

Check the portable UPS power supply cabinet in a variety of driving components and printed circuit plug-in boards, the main power supply circuit, DC power supply circuit of each weld, the weld has no false welding, false welding and cracks, components have no burnt discoloration phenomenon.

Transformer coils and connecting devices and chokes for overheating, discoloration, delamination of the enameled wire off, connecting wire joints are secure.

For portable UPS stored for a long period of time, the UPS should be turned on and charged every 3 to 6 months, otherwise both the UPS host and the battery will be damaged.

General UPS has protection measures for battery discharge, but after discharging to protection shutdown, the battery can be restored to a certain voltage again, but then it is not allowed to reboot the UPS, otherwise it will cause the battery to be over-discharged. The portable UPS must be recharged before it can be put into normal use.
