Description
Technical field
The present invention relates to a kind of converter station valve hall fire tripgear logic judging method, belong to Microcomputer Protection technical field.
Background technology
Converter valve is direct current transportation key equipment, expensive, but the converter station valve hall fire incident occurred in recent years, implement to propose higher requirement to the fire-fighting of converter station valve hall fire.In general, the system shutdown time length that fire causes is relevant with the damaged condition of equipment, if fire can detect early and suppress, the system shutdown time is short, otherwise then long.After breaking out of fire, existing measure is only sent out alarm signal and can not to be stopped transport elimination fault at once, so relevant departments propose to change the valve Room fire hazard aerosol fog warning system of the current conversion station put into operation into tripping operation by warning, repeatedly hold a meeting for this reason, with each producer and designing institute, modification scheme is discussed.
In order to process valve Room fire incident in time, nearly 2 years some DC transmission engineering start, according to relevant departments, the valve Room fire modification scheme formulated is discussed and transform the fire-fighting of the valve Room, increase valve Room detector, increase valve Room fire trip protection.But for converter station valve hall, current fire Trip Logic determination methods judges that the detectable signal of ultraviolet detector in pole early detection device, the valve Room in all air inlet pole early detection devices, the valve Room is to determine the generation of fire, so not only very loaded down with trivial details, if when the detector wherein had breaks down, fault detector just cannot upload detectable signal, fire will be caused like this to occur but situation about not tripping, very serious accident may be caused.
Summary of the invention
The object of this invention is to provide a kind of converter station valve hall fire tripgear logic judging method, judge that tripping operation is not only loaded down with trivial details but also can occur but the problem of the serious accident not tripping and may cause because of fire in order to solve at present at present fire.
For achieving the above object, the solution of the present invention comprises a kind of converter station valve hall fire tripgear logic judging method, this fire tripgear carries out Logic judgment according to the detectable signal of detector, and detector to be divided in air inlet pole early detection device, the valve Room ultraviolet detector in pole early detection device, the valve Room.This logic judging method is: when early detection device detection in air inlet pole is without exception, if at least one pole, valve Room early detection device detection has abnormal at least one valve Room ultraviolet detector detection simultaneously to have exception, then fire tripgear action tripping operation; When air inlet pole early detection device detects abnormal, if at least two valve Room ultraviolet detectors detect exception, then fire tripgear action tripping operation.
Before carrying out Logic judgment, the state of air inlet pole early detection device, pole, valve Room early detection device, valve Room ultraviolet detector itself is detected.
If detector itself exists fault, then send alarm signal, simultaneously locking this itself there is the acquisition mode of the detector of fault.
First whether logic judging method provided by the invention judge extremely to the signal of air inlet pole early detection device detection, when there is no anomaly, if at least one pole, valve Room early detection device detection has abnormal at least one valve Room ultraviolet detector detection simultaneously to have exception, then fire tripgear action tripping operation; When having abnormal, if at least two valve Room ultraviolet detectors detect exception, then fire tripgear action tripping operation.By successively detecting the detectable signal of three kinds of detectors, and according to Logic judgment, effectively fire is reported to the police.
Further, when minimum need two detectors have abnormal, can judge that fire trips, logic judging method provided by the invention does not need all detectors all to participate in Logic judgment, not only makes Logic judgment easier; And it also avoid the situation causing Logic judgment wrong because of the breakdown detector had.
In addition, before carrying out fire Logic judgment, to detect ultraviolet detector state in pole early detection device, the valve Room in air inlet pole early detection device, the valve Room, if there is fault in itself, then send alarm signal, judging its detector acquisition mode of locking in Trip Logic simultaneously, making it not affect logic export and judge.The fault eliminating these three kinds of detectors itself, on the impact of fire Logic judgment, makes fire Logic judgment more have reliability and accuracy.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
A kind of converter station valve hall fire tripgear logic judging method, this fire tripgear carries out Logic judgment according to the detectable signal of detector, detector to be divided in air inlet pole early detection device, the valve Room ultraviolet detector in pole early detection device, the valve Room, this logic judging method is: when early detection device detection in air inlet pole is without exception, if at least one pole, valve Room early detection device detection has abnormal at least one valve Room ultraviolet detector detection simultaneously to have exception, then fire tripgear action tripping operation; When air inlet pole early detection device detects abnormal, if at least two valve Room ultraviolet detectors detect exception, then fire tripgear action tripping operation.
Based on above technical scheme, by reference to the accompanying drawings, provide with next embodiment.
The valve Room fire fighting detector of valve Room fire tripgear access three types: ultraviolet detector in pole early detection device, the valve Room in air inlet pole early detection device, the valve Room.Each detector accesses three signals: the normal ON signal of fault-signal, state, the normally closed signal of state.
Three kinds of detector electric power loops of access fire tripgear can keep independent; device internal logic introduces soft pressing plate control word; control the detector quantity introducing relay protective scheme; probe state can be shielded utilize control word when the detector not introducing fire tripgear or introducing device breaks down, jitter overhauls; be not counted in device tripping operation decision logic, concurrent alarm signal is exported by network.Fire tripgear itself improves self-checking function simultaneously, and self-test signal is also exported by network, can monitor the malfunction of Access Probe device, and according to the action tripping operation after Logic judgment of detector acquisition mode.
Before carrying out fire Logic judgment, ultraviolet detector state in pole early detection device, the valve Room in the air inlet pole early detection device accessed, the valve Room is detected, if its probe itself exists fault, then sends alarm signal, gone out by network interface communication transfer; Judging its detector acquisition mode of locking in Trip Logic simultaneously, making it not affect logic export and judge.In the normal situation of detector itself, through fire tripgear Logic judgment and action tripping operation.
As shown in Figure 1, device Trip Logic introduces rest-set flip-flop, and trigger adopts preset priority, ensures that relay protective scheme tripping operation can export in time.During detector fault-free, often opening normally closed node disconnection while that node closing and think that detector detects abnormality, closing the reset of detector's status abnormality when often opening normally closed node while that node disconnecting.By rest-set flip-flop, each detector's status is confirmed, then according to the detectable signal that the detector after determining exports, carries out Logic judgment by the following two kinds situation:
When the early detection device detection of air inlet pole is without exception, if at least one pole, valve Room early detection device detection has abnormal at least one valve Room ultraviolet detector detection simultaneously to have exception, then fire tripgear action tripping operation, as shown in Figure 2.
When air inlet pole early detection device detects abnormal, if at least two valve Room ultraviolet detectors detect exception, then fire tripgear action tripping operation, as shown in Figure 3 (" >=2 " representative at least two input signals in Fig. 3 are " 1 ", and output signal is just " 1 ").
