Special storage battery maintenance base station

Battery maintenance is the key to the whole power supply maintenance work and everything revolves around the work power maintenance.In general, valve control type lead acid battery maintenance is the key to control the temperature of the environment and the battery charge and discharge, thus control the battery charge and discharge is an important part of the storage battery maintenance.Battery charging into floating charge and equalizing charge.So-called floating, refers to the mains is normal, the battery and switch power supply in parallel operation, switching power supply output voltage accord with the requirement of battery manufacturers, 2.23 V/only commonly, used to meet the needs of the self-discharge of the battery, oxygen cycle.Float charging pressure, from the definition, can only meet the needs of the self-discharge of the battery, oxygen cycle, not as a supplementary charge after the battery discharge.Battery charge complement is accomplished by equalizing charge of switch power supply.Are charging, the charging voltage to 2.35 V ~ 2.40 V/only, with less than or equal to 0.10 C10A current for the battery, the charging process of switch power supply is through the control of the Settings, by intelligent control switch power supply.In daily maintenance, through regular inspection on its dynamic environment monitoring system, to prevent rectifier equipment parameters, avoid to cause cell damage.

1. The battery type configuration

Battery use undeserved, will directly affect the running effect and service life of battery later, especially the base station batteries are greatly influenced by grid, more should pay attention to its selection skills.In the model selection of the base station batteries should consider mainly load properties and the size of the load, engine load requirements and basic support battery time three factors.

Size: (1) the nature of the load and load including main power consumption equipment, transmission equipment power consumption and electricity consumption monitoring equipment.

(2) the engine load requirements: housing after processing load.For security reasons, when all the equipment after the installation shall not exceed the building load.

(3) battery basic support time: refers to the communication power supply equipment failure after emergency processing time, usually based on the utility conditions determine its support time, generally choose 8 ~ 10 h support time.

Base station of main equipment of power supply requirements are not high switching equipment, base station power supply block not to cause data loss, no two sets of batteries in parallel.After we use for a long time observation, in the base station in grid environment, two groups of cells in parallel for use in harsh conditions for a long time, because the two sets of completely in two different chemical battery set, influenced by the cell attachment and nut and tighten, not the power supply is consistent with the internal resistance of the two groups, after a period of time after the operation, the battery internal resistance to change and make the individual battery for long added behind the battery charging, so that the battery capacity of damage probability is a set of batteries used alone.The author thinks that the base station battery configuration a set as well.

2. Preview preventive repair and maintenance

Any equipment failure happened from accumulation of insecure factors (increase over its equipment allowed limit) to the process of concentrated outbreak.We only have further familiar with the influence of environment factors on its, actively take preventive measures, to master the initiative of maintenance work.

Affect the normal operation of the power equipment of three factors: the influence of seasonal variation of power;The influence of artificial factors on the power supply system;Aging of the equipment.

(1) the seasonal variation of power: the influence of the fog had after winter, outdoor line insulation ability is reduced, heating appliances, is a power failure on Tuesday.In addition, humidity is big, summer weather insulation ability is relatively low, refrigeration appliances mass increase, is a power failure on Tuesday.To prevent major accidents, eliminate accident hidden trouble, should strengthen the security checks, check key for mains introduce circuit, variable distribution equipment and air conditioning unit, etc.

(2) human factors influence on power system: for rural public transformer to 380 v or 220 v power supply, should prevent major breakdowns caused by fire zero to make wrong.

(3) equipment aging: this kind of fault for cable line more aging.
