Accompanying drawing explanation
Fig. 1 is a kind of blower fan cooling fluid leak protection device circuit diagram of the present utility model;
Fig. 2 is another kind of blower fan cooling fluid leak protection device circuit diagram of the present utility model;
Accompanying drawing illustrates: 1-warning circuit, 2-fan safe chain in end, 3-fan safe chain out end, the normally opened contact of BJ-warning device, LY-apparatus for testing weeping, LY-1-apparatus for testing weeping, the normally-closed contact of LY-2-apparatus for testing weeping, KA-relay, the normally opened contact of KA-1-relay, SB-point driving switch.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 and embodiment, the utility model is further introduced, but not as to restriction of the present utility model.
With reference to the cooling fluid leak protection device circuit diagram of the present utility model shown in figure 1 and Fig. 2, this cooling fluid leak protection device comprises apparatus for testing weeping LY, the warning circuit 1 be connected with apparatus for testing weeping LY respectively and fan safe chain, warning circuit comprises a warning device BJ, and warning device BJ is connected with the normally opened contact LY-1 of apparatus for testing weeping; Fan safe chain is connected with the normally-closed contact LY-2 of apparatus for testing weeping, connects between air inlet fan theft-resistant link chain in end 2 and fan safe chain out end 3 by normally-closed contact LY-2.
When apparatus for testing weeping LY has detected leakage, the normally-closed contact LY-2 of apparatus for testing weeping LY has disconnected, and fan safe chain disconnects, and blower fan quits work; The normally opened contact LY-1 of apparatus for testing weeping LY closes simultaneously, and form loop with warning device BJ, warning device BJ gives the alarm.Maintainer is after blower fan action, the out-of-work reason of blower fan is judged by checking warning device whether to work, if warning device sends warning, then illustrate it is cause blower fan to quit work because there being leakage, if warning device does not send warning, then illustrate it is because other reasons causes blower fan to quit work.
Warning circuit 1 also comprises a relay K A in parallel with warning device BJ, and the normally opened contact KA-1 of this relay K A is in parallel with the normally opened contact LY-1 of apparatus for testing weeping LY.After contact LY-1 is closed, warning device BJ gives the alarm, simultaneously relay K A adhesive, and contact KA-1 closes, now loop self-locking.
Owing to during cooling fluid seepage may be periodically water clock, during cooling fluid seepage, warning device sends warning, when cooling fluid is non-leakage, warning device does not then send warning, and if maintainer check time warning device do not send warning, maintainer then judges not have leakage, and in fact having had cooling fluid seepage, maintainer then cannot Timeliness coverage clear up leakage.Loop auto-lock function then can prevent this type of situation from occurring, and after the self-locking of loop, warning device is in "on" position always, no longer sends warning, so that staff's Timeliness coverage cooling fluid seepage by the impact of the interim water clock of cooling fluid always.
Warning circuit also comprises a reset switch SB, and preferably this reset switch is a crawl switch S B, and this point driving switch SB connects with warning device BJ and relay K A.When after the self-locking of loop, warning device is in alarm condition always, maintainer can have leakage place according to warning prospecting and clear up leakage in time, after having cleared up leakage, has pressed point driving switch SB and resets, now relay K A dead electricity, contact KA-1 disconnects, if leakage is not cleaned out, then warning device continues to report to the police, if leakage is cleaned out, then warning device is no longer reported to the police.Maintainer can judge whether residual leakage accordingly.
Warning device BJ is preferably an indicator light, and during energising, indicator light is bright; More preferably a buzzer, sends buzzing alarming during energising.
Apparatus for testing weeping LY comprises a leakage detection alarm device and a liquid leakage detection line, the normally opened contact LY-1 of leakage detection alarm device is connected in warning circuit, the normally-closed contact LY-2 of leakage detection alarm device connects in air inlet fan theft-resistant link chain, one end of liquid leakage detection line is connected with the internal circuit of leakage detection alarm device, the other end is connected with the joint of measuring point to be checked, and apparatus for testing weeping working power adopts AC220V.
Liquid leakage detection line is a kind of novel humidity sensing element adopting high-molecular organic material to make, in the humidity sensing range of liquid leakage detection line, when air humidity reaches preset value, liquid leakage detection line is made moist, the leakage detection alarm device internal circuit current value be connected with liquid leakage detection line changes, and the normally-closed contact LY-2 of apparatus for testing weeping disconnects, and blower fan chain is out of service, the normally opened contact LY-1 of the detection alarm of leakage simultaneously device closes, and warning circuit is reported to the police.Realization like this, when cooling fluid has seepage, disconnects fan safe chain protection blower fan immediately, cooling fluid seepage is sent to the object of warning simultaneously.
Wherein, the semaphore of leakage detection alarm device exports three terminals, be respectively Chang Kaiduan NC, normal-closed end NO and common port COM, Chang Kaiduan NC is connected with the LY normally opened contact LY-1 of leakage detection alarm device with common port COM, and Chang Kaiduan NC is connected with apparatus for testing weeping LY normally-closed contact LY-2 with common port COM.
Warning device BJ and point driving switch SB is arranged on the cabinet door of rack, and maintainer, when whether detection has leakage, seeing if there is leakage without the need to going out to look into liquid leakage detection line, only need check whether warning device works on the cabinet door of rack.Such as, when warning device is an indicator light, maintainer only need check on cabinet door whether indicator light lights can judge whether leakage, when warning device is a buzzer, whether maintainer only need monitor has buzzer to have judged whether leakage, after having cleared up leakage, reset by the point driving switch SB on lower cabinet door, detected and whether also have leakage.
