Description
Technical field
The utility model belongs to the DC power supply field of transformer and distribution power station, particularly relates to a kind of accumulator tank for transformer and distribution power station direct current system.
Background technology
Operation and control system for transformer station or switchyard (following unified referred to as transformer and distribution power station) provides the direct current system of power supply, it is the heart of transformer and distribution power station, and the power of constantly beating maintaining heart is storage battery, once storage battery breaks down, directly have influence on the safe operation of electrical network.
A transformer and distribution power station is once after putting into operation, and the direct current system in standing just has been started working simultaneously.Valve controlling type accumulator conventional at present, although eliminate special maintenance work, it is very high to temperature requirement.Special in hot environment situation, the capacity of valve controlling type accumulator is just difficult to abundance, and direct current system cannot be monitored battery capacity.Therefore, create one good, adapt to the environment that storage battery long period normally runs, be necessary.
Find from the process of in the last few years storage battery in transformer and distribution power station being carried out to activation experiments, the life of storage battery that current transformer and distribution power station uses and capacity all owe desirable.
The result (table 1) of 50% property checked electric discharge is carried out from eight transformer and distribution power stations of random sampling, after battery has run 5 or six years under field conditions (factors), the service life of storage battery and battery capacity are difficult to the engineering philosophy reaching Utilities Electric Co. of city defined.
Table 1: certain electric company's transformer and distribution power station storage battery checking discharge and recharge result
Through investigating and consult related data and document display, storage battery and temperature have substantial connection:
1, the relation of battery capacity and temperature:
