Embodiment
Below, preferred implementation of the present utility model is explained with reference to accompanying drawing.
As shown in Figure 1, according to a kind of main transformer radiator automatic water spraying heat sink of the present utility model, comprise the water pipe 8 that is arranged on main transformer radiator 4 upper end, described water pipe one end is connected with water supply pipe, the other end is water pipe plug 5, described water pipe is established common valve 7, electromagnetically operated valve 6, described water pipe path arranges multiple drenching sprayer 3, described electromagnetically operated valve 6 connects a control loop, and this control loop can open or close by Controlling solenoid valve manually or automatically.
Described control loop comprises a transformer oil surface thermometer and a Digital Displayed Temperature Controller be connected with described thermometer, and the total low contact of height of described temperature controller is connected with a temperature-control circuit.
As shown in Figure 2, described temperature-control circuit is:
Two grades of one or two knob ST are accessed input point that is manual, controlling brancher automatically, respectively for selecting the break-make of Controlling solenoid valve manually or automatically;
Non-follow control branch road is: a pair stopping normally-closed contact SB1 of the input point serial connection start/stop control button of Non-follow control branch road, start a pair of described control button normally opened contact SB2 in parallel with a pair normally opened contact KM1 of A.C. contactor after, then to connect with described ac contactor coil KM;
Automatic controlling brancher is: total contact of the input point serial connection temperature controller of controlling brancher 9. automatically;
After 8. the high contact of temperature controller connects with the first auxiliary relay coil 1ZJ, then with another of the second auxiliary relay, normally-closed contact 2ZJ2 is connected;
After 10. the low contact of temperature controller connects with the second auxiliary relay coil 2ZJ, then connect with a pair normally-closed contact 1ZJ of the first auxiliary relay;
The input point of automatic controlling brancher is also connected in series the normally-closed contact 2ZJ1 of the second auxiliary relay, then is connected in series the normally opened contact 1ZJ of the first auxiliary relay, then connects with described ac contactor coil KM;
After another of described A.C. contactor is connected with electromagnetically operated valve 6 to normally opened contact KM2, then with air switch 22 and 220V power series.
The higher limit of described temperature controller is set to 80 degree, and lower limit is set to 70 degree.
The principle of temperature-control circuit is described below in conjunction with Fig. 2.
When rotary switch ST being beaten " automatically " position, if when reaching the higher limit 80 DEG C that temperature indicator is arranged, temperature indicator K2 terminal 8,9 closing of contact, the charged adhesive of auxiliary relay 1ZJ coil, 1ZJ normally opened contact closes, the charged adhesive of A.C. contactor KM coil, and KM2 normally opened contact closes, solenoid valves is opened, and starts trickle.
If when trickle is cooled to the lower limit 70 DEG C that temperature indicator is arranged, temperature indicator K2 terminal 8,9 contact disconnects simultaneously, 9,10 closings of contact, the charged adhesive of auxiliary relay 2ZJ coil, 2ZJ1 normally-closed contact disconnects, A.C. contactor KM coil losing electricity, and KM2 normally opened contact disconnects, electromagnetically operated valve power-off is closed, and stops trickle lowering the temperature.
If automatic control section breaks down, cisco unity malfunction needs maintenance, and when needing trickle to lower the temperature, now, need use manual operation liquid distribution.When rotary switch ST being beaten " manually " position, press " startup " button, the charged adhesive of A.C. contactor KM coil, KM2 normally opened contact closes, and solenoid valves is opened, and starts trickle.Due to the charged adhesive simultaneously of KM1 normally opened contact, when unclamping start button, loop also can not disconnect.When trickle need be stopped to lower the temperature, press " stopping " button, A.C. contactor KM coil losing electricity, KM2 normally opened contact disconnects, and electromagnetically operated valve power-off is closed, and stops trickle lowering the temperature.
During use, water pipe and tee pipe fitting are arranged in radiator top planes also fixing, then connect running water, spherical drenching sprayer is arranged on water pipe, electromagnetically operated valve and common valve are arranged on water pipe, open sky with electric drill, holding electrical element is installed, use insulated conductor wiring, after wiring, the confirmation of contrast drawing, after the confirmation of contrast drawing, smooth wire, reaches goodlooking object.
The guidance panel of temperature digital display display arranges higher limit 80 DEG C, lower limit 70 DEG C, power turn-on switch, check that each element is without exception, open water pipe common valve, rotary switch is got to " manually " position, press " startup " button, now solenoid valves opening, start trickle simultaneously, check that each portion of water pipe is without image of leaking, and checks that each device activity is sensitive simultaneously.Press " stopping " button, close after electromagnetically operated valve power-off, and stop trickle.Rotary switch is got to " automatically " position, if when reaching the higher limit 80 DEG C that temperature indicator is arranged, liquid distribution is opened, if when reaching the lower limit 70 DEG C that temperature indicator is arranged, liquid distribution cuts out, and thus realizes automatic water spraying.
This device is simple to operate, and temperature control automatic spraying device is reliably sensitive, meets during peak crosses the summer, only the rotary switch on control cabinet need be beaten to " automatically " position, can realize full-automatic cooling by temperature control.Through onsite application, main transformer at full capacity time cooling fast, decrease the main transformer overheating operation time, eliminate the hidden danger causing insulation to reduce because of transformer overtemperature, ensure that equipment safety operation.
