The normal operation of communication equipment.Therefore, the stability of battery and it can be supplied to the actual capacity pair of load during discharge
Ensure that the safe operation of power equipment has a very important significance.
However battery is after the use of certain time, Chang Yiyin active material falls off, the deformation of grid corrosion or pole plate,
The factors such as vulcanization, and gradually decrease capacity until failure.So finding out behindhand battery, and handled, to eliminate
Hidden danger is exactly the work of vast battery service personnel.Carrying out electric system uses always anti-acid flame-proof formula plumbic acid in the past few decades
Battery has accumulated certain experiences.
Lead-acid accumulator needs often to carry out maintenance work, generallys use in the prior art to the maintenance of lead-acid accumulator and is
System power-off, and lead-acid accumulator is replaced, then multiple energization is carried out to system, the time of general full maintenance is in a hour to two
Between hour, this has resulted in electric system and has turned off within a certain period of time, and for electric system, system shutdown is easy
Security risk is generated, and a large amount of cost of human and material resources can be generated.
Summary of the invention
The technical problem to be solved by the present invention is to the replacement lead-acid accumulators of electric system in the prior art to need to turn off electricity
One to two hours of Force system, for electric system, system shutdown is easy to produce security risk, and can generate a large amount of
, and it is an object of the present invention to provide a kind of be used for electric system secondary side device battery more changing device, solution is above-mentioned to ask cost of human and material resources
Topic.
The present invention is achieved through the following technical solutions:
One kind being used for electric system secondary side device battery more changing device, including shell, battery load-bearing part and executive item；Institute
