1. Establish a correct attitude
In an environment with fierce market competition, users should realize that the proper use and maintaining good UPS device means:
1. Few power outage-bring better service quality and improve customer satisfaction.
2. longer service life-save investment costs.
3. Faster device maintenance response speed-when you can accurately report the equipment model and fault characteristics, you can get a faster repair response from the supplier.
2. Manage the management of UPS accessories and accessories
1. Manage the manual management
UPS managers of outlets often change. UPS devices of all units in the province may also have different power and different models. Therefore, they should try to save the equipment of the device as much as possible, and to understand basic operations and daily maintenance from time to time. we suggest:
(1) Operation manual random machine storage;
(2) Store the electronic version for managers to download.
2. Management of damaged accessories
UPS devices are generally randomly configured with vulnerable parts such as fuses, but after these accessories are stored for a period of time, they often can't find it when they are used. we suggest;
(1) The accessories of the accessories are stored. Generally, it can be packed with plastic bags and adheres to the machine. In actual operation, this method is not easy to lose;
(2) The management personnel are collected unified management.
3.The specifications of the distribution line
1. The necessity of power distribution specifications
(1) The standard distribution line with standardized standards is the prerequisite for the normal operation of UPS;
(2) The proportion of UPS failures caused by line problems;
(3) The power distribution line should be standardized or later transformed before the equipment is put into use.
2. The problem of existence of outlet wiring
(1) The power distribution line is chaotic and the labeling is unclear. For example, there is no mark on the power distribution cabinet, which is difficult to distinguish the lines, which devices are power supply to the power, whether it is in the input zero line or output zero line of UPS.
(2) The UPS output socket is not clearly marked, and it is easy to cause other electric equipment access. This is a large part of the cause of failure found in maintenance. Although UPS already has some protection functions, it cannot be guaranteed to cope with various situations, such as welding machines, outlets in winter high -power heating machines, electric kettles, etc. are the easiest to enter the UPS output socket.
(3) Insufficient line capacity can easily lead to heat and fire. Some outlets had fewer equipment during the decoration, and the line diameter of the entry and exit line was not enough. With the increase of the outlet equipment, many circuits operated overloaded, resulting in the heating of the line, which was a hidden danger of summer fire.
(4) No power distribution drawings that can be used as a reference. At present, some outlets are already large, and the distribution lines are also very complicated, but there is often no distribution diagram for reference. When there is a problem with the line, the cloth is a dark line, and it is difficult to find the difficulty.
(5) Output zero -line ground wire connection. On the output of UPS to the socket line, it is generally not covered by dark lines, while some electricians do not follow the rules of electrician, zero, and ground wires. The problem of the zero -ground line is connected, and most of the ground ground can be done, and the load can be powered on, but the situation of poor communication and the burning computer power supply often occur. Experience can be solved.
(6) Unqualified zero voltage. Some outlets had no ground lines. Instead, the ground wire is used to connect to the tap water pipeline. Some outlets were originally ground resistance, but over time, and not detection and maintenance for many years, its ground resistance has greatly exceeded the standard. : One is to threaten personal safety; the second is that it is not good for the operation of the device. Most of the casual bars have EMI filtering on the input end. The effect must be grounded. Larger. Therefore, each outlet should check whether the wiring circuit has the above six major problems, and should be transformed as soon as possible if the conditions permit.
4. Outlet UPS is used correctly
Generally speaking, the UPS power of the outlet configuration is relatively small, and its operation is relatively simple. As long as the outlet personnel have to master some principles.
1. Clarify the opening and shutdown of UPS
(1) General start-up order; start the end of the UPS-bypass, the inverter starts-turn on the load
(2) General shutdown order; turn off the load-turn off the inverter-UPS turning the road-turn off the UPS power supply
(3) When there is a power outage during the day, it needs to be charged at night, just turn off the UPS inverter and do not need to turn off the UPS power switch to use it at night to charge Operation Manual).
2. Understand the various instructions and alarm signals of UPS
The current UPS generally has a wealth of display functions. For example, if the LCD LCD display function is provided, the parameters commonly used in UPS can be displayed (load size, city electric voltage, output voltage, battery voltage, charging current, etc.). Personnel should be able to know the meaning and operation of various display. When UPS has abnormal conditions such as overload, battery under pressure, failure, etc., alarm signals are generally issued, and identification should be found in time.
3. Emergency treatment
(1) Fire: When UPS is on fire, it is not allowed to extinguish water. All switches of UPS should be turned off in time to extinguish the fire with a foam fire extinguisher.
(2) Water entry: When UPS enters the water at the bottom of the rainy season due to the outlets, the UPS's electric input switch should be turned off in time to disconnect the connection between the battery and the UPS host to prevent the loss of losses.
5. Daily maintenance of UPS
1. UPS host
(1) The use environment of UPS should be well ventilated and clean. Do not place debris on the machine.
(2) Make a clear label on the output socket of the UPS to prevent unrelated power equipment access. First, try not to bring large emotional loads, such as electric motors, air conditioners, welding machines, refrigerators, etc. Small fans, etc., the industrial frequency UPS can generally be brought, and the high -frequency machine is best without it. Access.
(3) The load control is about 70%of the UPS nominal power.
(4) When turning on the load, follow the principle of bigger and small.
(5) In areas where there are more dust, it should be cleaned once every two years.
(6) For the long -term partial bottom ( ≤ 160V) of the municipal electricity, a width voltage voltage regulator should be considered to ensure that the battery can be fully charged in time after discharge.
2. Battery maintenance
At present, there are two types of configuration of UPS of the outlets. One is that the configuration standard delay UPS plus motor has reached Loan -delay power supply, another long -delay model of the battery of 4 to 8 hours of configuration delay is used. because The maintenance, noise, and gasoline storage of gasoline generators are more troublesome. Generally many. At present, the battery adopted by UPS of the outlets is generally a closed -lasting maintenance battery of 3 years of life. Although it is called
In order to avoid maintaining the battery, you still need to pay attention to some matters in use, otherwise the service life of the battery will go Can't reach the design life. The following is the daily maintenance precautions of the battery:
(1) The battery should be installed in a timely manner and charged in time.
(2) In areas where the power grid is better and has no power outage for a long time, the electricity should be disconnected every month, so that the battery is carried for 10-30 minutes to reduce the battery to reduce the battery inert The capacity is too fast.
(3) In fact, the battery should be charged in a timely manner for the currently parking areas. For batteries to be stored for a long time, they should be sufficient before storage, but the storage period should not exceed 3 months.
(4) Different models, capacity, manufacturers, and batches of batteries are prohibited.
(5) Forbidden depth discharge. Small load discharge for a long time, often leading to the shortened battery life (some new UPS have intelligent adjustment of battery under pressure protection points to solve this problem). It is recommended that the dot load is too small (such as the 6kva4 -hour UPS and the load of the outlet is only about 1kva. ) When power outage, UPS is best to work until 4 to 6 hours before shutting down to avoid deep discharge.
(6) Prevent the battery from overcharging. The general UPS charger is designed to be fully automatic, but when the parameters of the charger drift, it may cause the battery to charging damage due to excessive charging voltage. Usually check the display function; 20-25 ° C is the best operation of the battery. Temperature, so the outlet ZUI is good to place UPS and batteries in rooms with air conditioners, but it is also necessary to pay attention to the northern outlets that cannot be installed by the battery and the radiator, so as to avoid the temperature of the battery too high in winter.
