Description
Technical Field
The invention belongs to the technical field of power grids, and relates to a method for monitoring the oxidation condition of a battery pole of distribution automation equipment.
Background
At present, along with the gradual development of distribution network construction, some automation equipment are already applied to distribution network lines, and the power consumption sources of the automation equipment are two generally, firstly, the high voltage is obtained and converted into low-voltage power supply power consumption, and secondly, the storage battery pack is arranged for power supply power consumption. Under the normal operating mode of circuit, the automation equipment adopts usually to change high pressure to low pressure power supply power consumption and use, and the relevant power module of the storage battery cooperation of configuration lasts to charge, and until circuit tripping operation trouble has a power failure or when overhauing and having a power failure, automation equipment loses high-pressure side end power, and storage battery becomes by the charged state become the discharge state this moment, provides the electric energy for the normal operating of automation equipment in short-term. Presently, a lead-acid battery is one of the battery systems that is typically representative of the battery systems. The lead-acid accumulator has the advantages of stable electromotive force during discharging, stable working voltage, wide range of using temperature and using current, capability of charging and discharging for hundreds of cycles, good storage performance (especially suitable for dry charge storage) and low cost, thus having wide application. Lead-acid storage batteries are used in most of the conventional distribution network automation equipment (FTU, DTU and the like), so that the method is mainly used for monitoring the oxidation condition of the lead-acid storage battery pole of the distribution network automation equipment in real time and application.
The normal operation of the storage battery pack is related to the battery health degree and the pole oxidation degree of the storage battery pack. When the pole is oxidized, the original good metal connection can be damaged, virtual connection occurs, the conductive capacity is reduced, and the conductive connection can be blocked in severe cases. In addition, because the storage battery pack is arranged in the power distribution cabinet and the power distribution box, the information of the oxidation degree of the pole of the storage battery pack cannot be obtained in time through approaches such as background detection and the like unless the cabinet door is opened in inspection.
In addition, distribution network automation equipment has the function of detecting "backup power supply is abnormal" (whether the voltage of a lead-acid storage battery pack with a backup power supply is normal or not, whether the lead-acid storage battery pack with the backup power supply is connected or not and the like) but cannot judge the oxidation condition of the pole of the storage battery pack, the pole can be detected when the oxidation is very serious and the storage battery pack is connected into a power supply loop and fails due to oxidative fracture, the pole is late, the detection level is low, the efficiency is not high, and therefore the function cannot realize the monitoring function on the problem of monitoring the oxidation of the pole of.
The existing maintenance method only finds problems through manual daily periodic field maintenance and inspection, and changes in batches in three years (or a certain year).
Therefore, when a line tripping fault has power failure or maintenance power failure, the automatic equipment loses a high-voltage side power supply, but the automatic equipment cannot normally work due to the fact that electric energy cannot be obtained from the storage battery pack due to the fact that the storage battery pack is subjected to post oxidation, and therefore the accuracy of fault isolation of the automatic equipment during fault operation, equipment operation and distribution network normal operation is greatly affected.
At present, in distribution network automation equipment, the existing maintenance method for the lead-acid storage battery pack only finds problems through daily periodic field maintenance inspection and inspection, and changes are carried out in batches for three years (or a certain year).
The oxidation of the lead-acid storage battery pole is mainly influenced by the following factors and has the disadvantages under the existing maintenance method:
1. influence of climatic environment factors. First, moisture: the south weather is rich in rainwater, including the special weather influences such as the return south weather and the spring water weather, and provides an environment with high air humidity for the storage battery in an outdoor switch cabinet and a switch box, so that the oxidation of the storage battery pole is aggravated; second, temperature difference: in the automation equipment, a part of equipment is in rural areas, fields and mountains, the temperature difference between day and night is large, and condensed water, moisture and the like can be caused in a distribution box and a distribution cabinet due to the temperature difference, so that the long-term weather influence is realized, and the oxidation of the storage battery can be aggravated. Meanwhile, the storage battery pack can also be affected by temperature to generate expansion and contraction effects, so that internal chemical substances are volatilized and overflowed, and the process of pole oxidation of the storage battery pack is aggravated. Because the daily periodic inspection cycle is too long, the number of automatic equipment is not small, inspection cannot meet the requirement, if the manual inspection is concentrated, a large number of personnel and vehicles need to be called, and the labor cost is increased rapidly. The existing periodic inspection cannot solve the problem, the rotation can be performed only by estimating the service life of the storage battery pack and setting the age, and the short age setting may replace some storage battery packs with good operation conditions, so that economic resource waste is caused.
2. Individual difference effects. The quality of part of lead-acid storage batteries is poor, the sealing performance of the batteries can be damaged when the batteries are frequently bumped before transportation and installation, so that internal acid liquid overflows when the batteries are used, and the subsequent acid liquid corrodes the poles to generate oxidation. Or when the charging current of some storage batteries is relatively overlarge, the relative volatilization of acid liquid in the batteries is relatively large, and then the acid liquid reacts with the poles to generate oxidation. And the service time of some storage batteries is too long, so that the acid liquid in the batteries is slowly volatilized to react with the battery poles to generate oxidation. The current maintenance method cannot meet the requirements under the relative individual conditions, and also shows that the oxidation state of each automatic equipment lead-acid storage battery pole cannot be monitored in real time by means of the prior art, and the monitoring is only carried out by daily work inspection (the monitoring quantity is small) and periodic inspection (the period is long), and the efficiency is low.

As a preferable technical scheme of the invention, the battery in the step (1) comprises a lead-acid storage battery.
The basic structure of a lead-acid battery is to insert electrodes made of lead dioxide and metallic lead into a dilute sulfuric acid solution. The method takes spongy lead as a negative electrode, lead dioxide as a positive electrode and sulfuric acid aqueous solution as electrolyte, and the spongy lead and the lead dioxide participate in electrochemical reaction of the battery. When the circuit is completed, the lead dioxide of the positive electrode gets electrons to become lead sulfate, and the lead of the negative electrode loses electrons to become lead sulfate.
When both the lead and lead dioxide solids become lead sulfate, the battery is discharged. If the lead sulfate on both sides is respectively connected with an external power supply at the moment, the lead sulfate connected with the positive electrode of the power supply loses electrons and becomes lead dioxide, and the lead sulfate connected with the negative electrode of the power supply obtains electrons and becomes lead under the action of current. That is, the battery is again fully charged.

The electrode is PbO2+2e-+4H++SO4 2－＝＝PbSO4+2H2O；
The total reaction formula during discharge is Pb + PbO2+2H2SO4＝＝2PbSO4+2H2O。
(II) during charging:
PbSO on (cathode) electrodes4The lead with the middle +2 valence is converted into Pb by 2 electrons sent by a power supply and then releases SO4 2－，
The electrode is PbSO4+2e-＝＝Pb+SO4 2－；
PbSO on (anodic) electrodes4The lead with the middle +2 valence is deprived of 2 electrons by the power supply to become the lead with the +4 valence, and the lead with the +4 valence is forcibly deprived of H2O of O2－To make itself become PbO2While at the same time making H2H in O+The release of the active ingredients is realized,
the electrode is PbSO4+2e-+2H2O＝＝PbO2+4H+；
So that the total reaction formula during charging is 2PbSO4+2H2O＝＝PbO2+Pb+2H2SO4
