Description
Technical field
The utility model relates to single the online dismounting electronic installation of battery, can not cause the online dismounting electronic installation of DC power supply interruption when removing single trouble accumulator in the dc operation power supply system of transformer station, ups power system, the power supply system for communications (three systems are connected with the positive and negative line that closes a floodgate respectively).
Background technology
At present; In direct current operative power source of substation system, ups power system, the power supply system for communications; Operating monocell group dc operation power supply system, ups power system, the power supply system for communications are also many; Want the substation safety of bonding battery pack dc operation power supply system, ups power system, the power supply system for communications to move reliably; Must adopt safe and reliable online detaching device, with guarantee direct current operative power source of substation system during single fault of online dismounting (backwardnesss) storage battery, ups power system, the power supply system for communications incessantly safety, reliably supply power.
Rules such as employed at present " analysing valve control type lead-acid accumulator battery operation and service regulations ", " storage battery operation and service regulations " are not all done specific (special) requirements to single fault (backwardnesss) the storage battery processing in the dc operation power supply system of monocell group, ups power system, the power supply system for communications.
During single fault of online dismounting (backwardness) battery-operated; The alternating current input power supplying of meeting dc operation power supply system, ups power system, the power supply system for communications has a power failure or when disappearing for some reason; Batteries is in off-state, and batteries can not be with the dc load operation.At this moment; If electric power system is broken down; Can fault further be enlarged because of direct current interrupts causing the protective device tripping in time not eliminate fault when protection starts the outlet tripping operation, cause large-area power-cuts and enormous economic loss; Influence system safety stable operation, bring negative social influence to electric power system.
The utility model content
The purpose of the utility model provides a kind of online detaching device of transformer station's portable mono trouble accumulator of the uninterrupted batteries power supply of ability when single trouble accumulator is removed.
This novel purpose is achieved in that the online detaching device of a kind of transformer station portable mono trouble accumulator; As being connected to diode D1 positive pole through lead with the anodal anodal connection-peg that is connected of trouble accumulator; It is anodal that diode D1 negative pole is connected to diode D2; Diode D2 negative pole is connected to as the negative pole connection-peg that is connected with the trouble accumulator negative pole through lead; And be connected to the negative pole connection-peg behind the anodal serial connection of the diode D3 switch DK, it is anodal that diode D3 negative pole is connected to diode D4, and diode D4 negative pole is connected to anodal connection-peg.
The model of above-mentioned diode D1, D2, D3 and D4 is 2CZ200A/800V.
This device only needs the only trivial hundreds of of the cost of several diodes and disconnecting link unit; In the work of single fault of online dismounting (backwardness) storage battery; Stable incessantly, the operation reliably of dc operation power supply system, ups power system, the power supply system for communications; To system safety, reliable, economical operation sound assurance is provided, and equipment breakdown can not have taken place, this is maximum economic and social benefit;
The maintainer is when the work that relates to batteries, and spirit often is in the high-pressure state, fears to make mistakes, and very easily causes the accident.But, exactly because stress is made a fault than being easier to fault judgement, processing, cause the accident at work.Now; Use single fault of portable online dismounting (backwardness) accumulator plant; Because reliability and fail safe improve, make the maintainer when relating to batteries work, can go to tackle accident analysis and processing with a kind of phychology of loosening more; Operating efficiency and repair quality have been improved greatly, for device security operation reliably provides necessary guarantee.
The advantage of this device is: apparatus structure is reasonable, and is simple and reliable, and has practical value.During removing single fault (backwardness) battery-operated; The alternating current input power supplying of meeting dc operation power supply system, ups power system, the power supply system for communications has a power failure or when disappearing for some reason, can not cause DC power supply to interrupt (promptly guaranteeing the uninterrupted power supply of batteries).

Embodiment
Fig. 1 illustrates; The online detaching device of this transformer station portable mono trouble accumulator, as being connected to diode D1 positive pole with the anodal anodal connection-peg that is connected of trouble accumulator through lead, it is anodal that diode D1 negative pole is connected to diode D2; Diode D2 negative pole is connected to as the negative pole connection-peg that is connected with the trouble accumulator negative pole through lead; And be connected to the negative pole connection-peg behind the anodal serial connection of the diode D3 switch DK, it is anodal that diode D3 negative pole is connected to diode D4, and diode D4 negative pole is connected to anodal connection-peg.The model of diode D1, D2, D3 and D4 is 2CZ200A/800V.Diode D1, D2, D3 are identical with the D4 model, all select heavy-duty diode for use.
This novel method for using is: the negative pole of portable online detaching device is linked to each other with the negative pole of storage battery; Anodal link to each other with the positive pole of storage battery (will guarantee when being connected that polarity is correct, be interrupted the operate as normal of dc operation power supply system, ups power system, the power supply system for communications) otherwise can in exchanging input, have no progeny.Remove any utmost point of fault (backwardness) storage battery, the online switch DK that removes accumulator plant again closes.When recovering single fault (backwardness) battery-operated, job order then in contrast.
During single fault of online dismounting (backwardness) battery-operated; Meet the alternating current input power supplying power failure of dc operation power supply system, ups power system, the power supply system for communications (three systems are connected with combined floodgate negative busbar HM-with combined floodgate positive bus-bar HM+ respectively) or when disappearing for some reason; Batteries is in closed discharge condition, and break down like electric power system this moment, and protection starts the outlet tripping operation can in time excise fault; Fault is further enlarged; Can not cause large-area power-cuts and enormous economic loss, can not produce negative social influence, thereby guarantee the stable operation of power system security reliable and economic.
