Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, a kind of electric substation air-conditioner water leakage alarm start-stop control system, also comprise testing circuit power supply, reference voltage source, air-conditioning power supply, leakage inductive rope, leak transmitter, comparator and normally closed type electromagnetic contactor, wherein testing circuit power supply, reference voltage source, leakage inductive rope, leak transmitter, the coil of comparator and normally closed type electromagnetic contactor forms leak water detdction circuit, described leakage inductive rope is arranged in the drainage pipeline outer wall of air-conditioning along the drainage pipeline setting direction of air-conditioning, the output termination of leakage inductive rope is leaked the input of transmitter, leak the first input end of output termination comparator of transmitter, second input termination reference voltage source of comparator, the first end of the output termination normally closed type electromagnetic contactor coil of comparator, the first end of the second termination testing circuit power supply of normally closed type electromagnetic contactor coil, second termination of testing circuit power supply is leaked the testing circuit power input of transmitter, the contact of normally closed type electromagnetic contactor is connected on air-conditioning power supply circuits, described testing circuit power supply, reference voltage source, the transmitter that leaks, comparator and normally closed type electromagnetic contactor are all arranged in leak water detdction case, leak water detdction case is made up of insulating materials, leak water detdction case is arranged on the pole on air-conditioning side, the unsettled setting of leak water detdction case, can prevent when electric substation's humidity is excessive, the components and parts short circuit of leak water detdction circuit or malfunctioning thus cause leak water detdction circuit not work, described comparator adopts single threshold compataror,

A kind of electric substation air-conditioner water leakage alarm start-stop control system, also comprise remote monitoring main frame and acoustic-optic alarm, described remote monitoring main frame is connected with transmitter communication of leaking by radio transmission apparatus, and acoustic-optic alarm is electrically connected with the output of remote monitoring main frame; Remote monitoring main frame is connected with transmitter radio communication of leaking, so just can obtain the water leakage that the transmitter that leaks obtains at any time, remote monitoring main frame is used for checking water leakage, the main frame of remote monitoring is simultaneously also for sending alarm signal to acoustic-optic alarm, such acoustic-optic alarm just can remind staff to go initiatively to check, significantly reduces the potential safety hazard brought because of slacking off of staff.

A kind of electric substation air-conditioner water leakage alarm start-stop control system, also comprise electronic flowmeter, electronic flowmeter is made up of sensor and converter two parts; The sensor setting of electronic flowmeter is in air-conditioning and drainpipe joint, and the output of the converter of electronic flowmeter is connected by wireless device communication with remote monitoring main frame, and remote monitoring main frame is for checking the flow signal that electronic flowmeter transmits; Normal conditions leaking air-conditioning is because drain line blockage, but leakage inductive rope senses that leaking also may be broken by drainpipe to be caused; But, because remote monitoring main frame also can be used for the flow signal checking that electronic flowmeter transmits, as long as the data when data on flows on remote monitoring main frame does not block with drainpipe are the same, just illustrate that drainpipe does not block, but broken.

Operationally, set leakage inductive rope and circuit on request, then open the switch of the transmitter that leaks, open air-conditioning switch because electromagnetic contactor is normally closed type electromagnetic contactor, so now air-conditioning by the work of being energized, the magnitude of voltage that the transmitter that leaks when air-conditioning is water-tight exports is as the reference voltage of comparator, namely at the second termination reference voltage source of comparator, if air-conditioning leaks again, leakage inductive rope exports a voltage signal after sensing leaking air-conditioning, this voltage signal enters comparator by the first end of comparator and reference voltage compares, because leakage inductive rope senses leak, the voltage that transmitter exports so leak will be greater than reference voltage, comparator output terminal is caused to export high level signal, if air-conditioning leaks always, comparator output terminal will export a lasting high level signal, this will cause the charged generation magnetic force of the coil of normally closed type electromagnetic contactor, magnetic force opens the contact of normally closed type electromagnetic contactor, air-conditioning power-off is out of service, meanwhile, long distance control system is to acoustic-optic alarm alarm signal, and acoustic-optic alarm warning reminding staff checks in time, from the display screen of remote monitoring main frame, staff can see that the flow that electronic flowmeter records is the same when whether not blocking with drainpipe, if data on flows is the same, then illustrate that drainpipe does not block, but drainpipe breaks, and needs staff to change drainpipe immediately, if the data on flows that electronic flowmeter records is less than data on flows when drainpipe does not block, then drainpipe blocking is described, staff just must clear up blocking drainpipe to electric substation at once, makes it to recover unimpeded.

First, whether the utility model have employed leakage inductive rope and the combination of the transmitter that leaks, leaked by air-conditioning and be converted into the signal of telecommunication intuitively, and testing result is accurate, and error is less; Secondly, the utility model have employed the core component of comparator as leak water detdction circuit, comparator fast response time and low price; Again, the utility model additionally uses remote monitoring main frame and acoustic-optic alarm, like this, even if staff is slack do not check remote monitoring main frame in time, acoustic-optic alarm also can remind staff to check remote monitoring main frame in time, so that solve a problem promptly, in order to avoid cause unnecessary loss; Finally, the utility model is also provided with electronic flowmeter at drainpipe water inlet, according to the data that remote monitoring main frame shows, staff just can judge that leaking air-conditioning is because drainpipe blocks or drainpipe breaks easily, rapid-maintenance is very helpful, the loss because leaking air-conditioning brings can be reduced as much as possible.
