The base station power system is one of the supporting support systems for mobile main equipment and transmission equipment, involving various professional subjects such as dynamic mechanics, chemistry, electronics, communications and automatic control technology, computer applications. The purpose of its maintenance work is to ensure that the communication equipment has continuous, stable, reliable energy, providing a normal operation of the communication device to ensure the safety of the system. In this regard, the maintenance personnel need to have certain professional skills. BeThere are many types of power supply, which has a large influence in external factors. If maintenance is unfortunate, the overall failure rate of the equipment will be very high, the power environment monitoring system lost utility, the operating cost is expensive, and the base station is not safe. In order to reduce operational costs, prevent the battery pack from scrapping, and now analyze the market environment and focus on power maintenance, and propose solutions. Be
First, the base station city power factor
In the entire communications industry, the environment in which the mobile communication base station is complicated, the construction of the main introduction is limited by the environmental conditions of the base station, the construction allocation requirements are different, and the maintenance requirements are different. If many base stations are built on high-rise or high mountains . Objectively speaking, the city's electric environment of the base station has no high demand, but the quality requirements of the battery have higher requirements, which increases many difficulties to the battery pack, if the maintenance is improper, will cause battery packs. Early failure. Be
(1) High-rise base station
Such base stations are in the city, which is generally stable in general. Two major factors affecting the city's electricity and electricity is: No self-proof oil machine power generation, the fault time is generally no more than 24 hours. For such problems, it should be taken to limit DC load measures under the power environment monitoring system to prevent the battery pack from being over-discharge, and then strengthen the maintenance of the battery afterwards. Be
(2) Alpine base station
Refers to the rural hilli base station away from the city, such base stations use farmers, high requirements for the maintenance requirements. The author believes that the construction of such base stations should be selected from the local conditions and security conditions, and there is a conditional introduction of 10kV high pressure market. In rural power supply, high-pressure city electricity is more than 380V, and the impact is affected by human factors. If possible, an automated generator set can be configured to automate AC power supply. The base station is located in rural hills. Because the mobile oil machine is inconvenient to access power generation, the base station is configured with an automatic power generation group, which has been discharged from the power generation problem, and the cooperation of the power environment monitoring system can also be handled in time. In this way, it is necessary to ensure that the foreign market is introduced to be stable, and the reliable security communication is unblocked. Be
(3) General base station
No matter what the base station should pay attention to the introduction of the market, the market introduction of any base station will experience a process from construction to maintenance, and then further optimize the complete optimization of the local electricity status to ensure that when the market is blocked. Reliably access the fixed oil machine or the mobile oil machine charges the battery pack. Therefore, the mobile oil machine power generation should be established“Mobile oil power generation system”To ensure instant, reliable, safe operation, to do battery maintenance under the mating of the power environment monitoring system. Be
Second, the battery maintenance
Battery maintenance is the focus of the entire power maintenance work, and all power maintenance is deployed around this work. Generally speaking, the key to valve-controlled lead-acid battery maintenance is to control the temperature of the environment and the charging and discharge of the battery, so controlling the charging and discharge of the battery is an important part of the battery maintenance. The charging of the battery is divided into floating charge and balance charging. The so-called floating charge refers to the normal operation of the battery and switching power supply in parallel, and the switching power supply output voltage is in line with the requirements of the battery manufacturer, typically 2.23V / only, used to meet the self-discharge of the battery, oxygen circulation. It can be seen from the definition that the floating voltage can only meet the self-discharge of the battery, the need for oxygen cycle, and cannot be charged as a battery discharge. Supplementary charging of the battery is accomplished by the equalization charging of the switching power supply. When charging, the charging voltage is increased to 2.35-2.40V.≤The current of the 0.10c10a is charged with the battery. The control of the charging process is achieved by the switching power supply intelligent control by the setting of the switching power supply. In daily maintenance, it can be checked on a periodic to prevent the change in rectifier equipment parameters to prevent the battery damage. Be
1, battery selection configuration
Improper use of the battery will directly affect the battery life and service life, especially the base station battery is larger, and should pay more attention to its choice. At the base station battery selection, you should focus on considering the load nature and load size, computer room load requirements and battery basic support time. Be
(1) Load properties and load sizes: including electricity consumption, electricity consumption and monitoring equipment for transmission equipment. Be
(2) Computer Room Load Requirements: The house is processed after treatment. For safety reasons, it is not allowed to exceed the building load after all equipment is installed. Be
(3) Battery basic support time: Mainly refers to the emergency treatment time after the AC power supply device has failed, usually determines its support time according to the main electricity conditions, generally selected 8 to 10h support time. Be
The base station main device has no exchange of power supply, and the blockage of the base station is not required to cause data loss. No two sets of batteries are used in parallel. After a long time to use, in the market, the two sets of batteries are not conducive to the battery for a long time in harsh conditions, because the two sets of batteries are completely in two different chemical sets, and the battery is connected and the nut is tightened. Impact, it is not easy to maintain the internal resistance of the two sets of power supplies. After a period of operation, the battery internal resistance changes to generate backward batteries due to long-term supplementation charging, thereby causing the probability of damaged battery capacity than a group. It is high when the battery is used alone. The author believes that the base station battery configuration is a good set. Be
Pre-inspection
There is a process of any device failure has a process from accumulation (increasing factors that exceed its device to allow the limit) to centralized outbreak. We only have more steps to familiarize yourself with the environmental factors on its environment, take the initiative to take preventive measures to master the initiative of maintenance work. Be
Three factors affecting the normal operation of the power supply: the effect of seasonal changes on power supply; human factors affect the power supply system; the aging of equipment. Be
(1) The impact of the season changes to the power supply: the rain fog weather, the outdoor line is insulated, so the increase in the heating electrical appliance is the process of power failure. In addition, the summer weather is large, the insulation is relatively low, so the large scale of the refrigeration appliance Increase is a power failure. In order to prevent major accidents, eliminate the hidden dangers, and should be strengthened, and the inspection is to check the market, the variable distribution equipment and the air conditioning unit, etc. Be
(2) The impact of human factors on power systems: For rural public transformers, 380V or 220V power supply should prevent major failures due to fire lines. Be
(3) The aging of the equipment: This type of failure is aging for the cable line. Be
Third, attach importance to the construction and maintenance of power environment monitoring system for power supply assistance equipment
The base station power environment monitoring system is to ensure that the remote online important test tool for the normal operation of the mobile supporting equipment is a supporting equipment maintenance base network, so the maintenance management of the base station power environment monitoring system is to ensure the stability of the remote power system. , The basis of reliable operation.
