Maintenance regulations for Yuasa battery

This procedure is prepared on the basis of relevant national industry regulations, combined with the actual needs of the customer's site, and integrating the technical accumulation made in many years of field service experience.

At present, lead-acid batteries are commonly used in communication and electric power, mainly including acid proof and explosion-proof batteries (hereinafter referred to as acid proof batteries

Pool) and valve controlled sealed battery (hereinafter referred to as sealed battery). The battery shall be used and maintained as required.

1. Requirements for battery room

The valve controlled sealed battery should be placed in the room with air conditioning (the room has regular ventilation device), and the temperature of the room should not exceed

30'c, no battery room. The following requirements for battery room are proposed for the acid proof and explosion-proof lead-acid battery room.

1) The room is well ventilated with ventilation device.

2) There should be enough lighting in the room. Sealed explosion-proof lamps shall be used for lighting, and the switch shall be set outdoors. Indoor floor, wall

Anti acid treatment shall be done for ceiling, doors and windows, ventilation equipment, etc.

3) There shall be safety protection facilities for street windows.

4) There should be water and water facilities and acid storage room in the room.

5) The indoor temperature of acid proof battery is kept at 5 ~ 35C.

6) Batteries shall be protected from direct sunlight.

2. Terminology

1） Initial battery inspection

In order to ensure the qualified performance of the new battery after being put into use, a series of battery performance tests must be carried out before installation and use. Battery initial

The inspection shall be carried out in accordance with the national regulations. If the conditions are available and necessary, all the preliminary inspection items shall be carried out, without relevant

Under the experimental conditions, the basic performance test shall be carried out, and the manufacturer shall be required to provide a formal battery performance test report.

2) initial charging

The first charge of a new battery before it is put into use to fully reach the state of charge. Working procedure of initial charging

Refer to the manufacturer's instructions.

3) Constant current charging

The charging current is in the range of charging voltage and is maintained at a constant value.

4) Equalizing charge

A charge made to compensate for the voltage unevenness of the battery in use and restore it to the specified range

Electricity.

5) Constant current and voltage limiting charging

First, charge in constant current mode. When the battery voltage rises to the limit value, the charging device will automatically switch to constant voltage charging,

Until the charging is completed.

6) floating charging

At the DC output end of the charging device, the battery and load are always followed, and the charging mode is constant voltage. Charging in normal operation 6) floating charging

At the DC output end of the charging device, the battery and load are always followed, and the charging mode is constant voltage. Charge during normal operation

The electric device recharges the battery while bearing the regular load, so as to compensate the self discharge of the battery and make the battery full

The capacity is in standby state.

7) Recharge

During storage, due to self discharge, the capacity of the battery is gradually reduced, or even damaged. According to the manufacturer's instructions, it should be carried out regularly

Charge.

8) Constant current discharge

During the discharging process, the discharging current value of tangshallow battery remains constant until it reaches the specified termination voltage.

9) Capacity test (battery)

The newly installed battery shall be charged according to the specified constant current. After the battery is full of capacity, it shall be charged according to the specified constant current

When one of the batteries is discharged to the termination voltage, the discharge capacity is calculated.

2.10 check discharge,

In order to test the actual capacity of the battery pack in normal operation, the battery pack shall be separated from operation and discharged at a constant current with the specified discharge current. As long as one of the single batteries is placed at the specified termination voltage, the discharge shall be stopped. Calculate the actual capacity of the battery 3. Basic tools for use and maintenance of the battery in the power room

The range of the instrument used shall be determined according to the measured current and voltage, and the reading shall be within the last third of the range.

1) Voltmeter requirements

The instrument accuracy of measuring voltage shall not be less than 0.5 level, and the internal resistance of voltmeter shall not be less than 1kq / v

2) Ammeter requirements

The accuracy of current measuring instrument shall not be less than 0.5 level

3) Thermometer requirements

The thermometer used for measuring temperature shall have a proper range, each graduation value shall not be greater than 1C, and the calibration accuracy of the thermometer shall not be less than 0.5c

4) Time instrument requirements

The instruments used for measuring time shall be divided in time, minutes and seconds, and shall not be less than the accuracy of soil LS / h.

5) Pressure gauge requirements

The accuracy of the instrument used for pressure measurement shall not be less than 0.25 grade or the equivalent.

6) Daily monitoring equipment

If conditions permit, it is recommended that each group of batteries be equipped with a daily monitoring instrument to realize real-time monitoring of batteries. The specific requirements are as follows:

The specific requirements are: in order to test the actual capacity of the battery pack in normal operation, the battery pack shall be separated from the operation to discharge electricity as specified

The current shall be discharged at a constant current, and the discharge shall be stopped as long as one of the single batteries is put at the specified termination voltage. Calculation of power storage

Actual capacity of pool group
