Description
Technical field
The utility model is related to battery pack open circuit afterflow technical fields, and in particular to a kind of storage batteries of transformer substation open circuit afterflow
Device.
Background technology
Transformer station direct current system is important component part in station, the reliable and stable operation of straight-flow system concerning in station after
The safe and stable operation of electric protection and automatic device etc..Therefore accumulator stability and load can be supplied in discharge process
Actual capacity to ensuring that the safe operation of power equipment has a very important significance.Under accumulator group accident discharge condition,
If the group storage battery wherein certain section accumulator or multiple accumulators have open circuit, accumulator loses stand-by power supply and ensures that 2~3 is small
When accident power supply design necessary function, lead to relay fail accident.
Utility model content
The utility model provides a kind of storage batteries of transformer substation open circuit current following device in view of the deficiencies of the prior art, and feature exists
In：The cathode of accumulator is connect with fuse 1 by conducting wire, and the anode of accumulator is connect with fuse 2 by conducting wire, fuse
2, which pass sequentially through triode, LED light, resistance R3, is connect with fuse 1 by conducting wire, by leading between fuse 2 and fuse 1
Line is connected with resistance R1 and resistance R2, is connected by conducting wire between triode and resistance R1 and resistance R2, fuse 2 and fuse
Relay and diode are connected with by conducting wire between 1, fuse 2 is connected with normally opened node with fuse 1 by conducting wire, normally opened
Node, relay and diode, resistance R1 and resistance R2 are in parallel connection.
The operation principle of the utility model is：Accumulator under normal circumstances, the ends current following device a, b respectively with current electric power storage
Pond connects, then at this time electromagnetic relay because diode does not turn on not excitation, the normally opened node of continuous current circuit opening state just
It will not afterflow；And triode is connected at this moment so that LED light is shinny, shows this batteries and is in normal condition；
Accumulator is once opened a way, then this batteries is replaced by current following device, and the diode voltage in device is by original
Backward voltage become forward voltage, current direction changes, and flowing through diode makes its forward conduction to relay excitation, often
Node closure is opened, operating current will be flowed through from current following device, realize the afterflow function of accumulator；And triode loses at this time
Pressure forms open circuit, causes LED light to be extinguished, show this batteries and currently open a way, and warning staff should do timely place
Reason.
The beneficial effects of the utility model are：
Current following device is installed additional by every batteries, and performance of the function for monitoring monitoring per batteries ensure that every batteries
Normal operation；Current following device ensure that the safe operation of other batteries, it is therefore prevented that battery pack is endangered because of the damage of certain batteries
The possibility of other batteries of evil, realizes the function of isolated fault；Accident rescue time has been won for staff, has prevented accident
Extension, to ensure that the safe and stable operation of entire straight-flow system；The current following device further ensures electrical secondary system
Safety and stability, reduce because accumulator group is out of service and caused by station in straight-flow system collapse so that whole station protect
Function loses and causes relay fail accident, reduces and higher level is caused to trip, and reduces the possibility of a wide range of power outages.
