Embodiment
With reference to the regulator cubicle schematic diagram shown in Fig. 1, regulator cubicle of the present utility model using the below of cabinet (1) sidewall paneling as air inlet, top is as air outlet, air inlet is installed air inlet fan (2), air outlet is installed air-out fan (3), when regulator cubicle works, hot-air can up move, then discharged in cabinet (1) by air outlet, and the relatively low air of ambient temperature enters in cabinet (1) by air inlet, reach the effect of airflow circulating inside and outside cabinet (1), thus reach the object of heat radiation.Air inlet and air outlet all arrange a woven cloths filter pad (5) of being comparatively altogether unjustifiable, not only change filter pad and cleaning very convenient, and be easy to observe to the clean condition of window, be beneficial to the process of operating personnel's Timeliness coverage, the failure rate of regulator cubicle can be reduced.The fan of the heat radiation on market all belongs to direct current machine, and direct current machine refers to and can convert direct current energy to mechanical energy, flows through direct current machine sense of current can change turning to of direct current machine by change.
When regulator cubicle powers on, run indicator (4) will work and shinny instruction, in the circuit theory diagrams of the control module (A1) shown in Fig. 2, because auxiliary relay coil (KM) is coupled in the two ends of run indicator (4), therefore when the voltage at run indicator (4) operationally two ends can be added in the two ends of auxiliary relay coil (KM), after the two ends of auxiliary relay coil (KM) define voltage, electric current will flow to the other end from one end of middle relay coil (KM), according to the principle of electric magnetisation, auxiliary relay coil (KM) two ends just define magnetic, by the normal open switch adhesive with armature, while the coating-forming voltage of auxiliary relay coil (KM) two ends, the two ends of very first time relay coil (KT1) also form voltage, but with auxiliary relay unlike, very first time relay is Delayed conducting, that is to electric current can be had to flow through afterwards after a while in very first time relay coil (KT1), and in response to first normal open switch (KT10) of very first time relay coil (KT1), first normally closed switch (KT11), second normal open switch (KT12), second normally closed switch (KT13), 3rd normal open switch (KT14) and the 3rd normally closed switch (KT15) are all time delay responses, with reference to the circuit theory diagrams of the driver module shown in Fig. 3, when normal open switch closes, electric current in first driver element (A2) will from the positive pole of external power source through the second normally closed switch (KT13), air inlet fan (2), normal open switch and the first normally closed switch (KT11) form loop to the negative pole of external power source, now define the rotation direction of air inlet fan (2) for rotating forward, after rotating forward one end time, in response to first normal open switch (KT10) of very first time relay coil (KT1), second normal open switch (KT12), first normally closed switch (KT11) and and the equal action of normally closed switch, now original closed the first normally closed switch (KT11) and the second normally closed switch (KT13) all disconnect, and the first normal open switch (KT10) originally disconnected and the second normal open switch (KT12) all closed, electric current will from the positive pole of external power source through the first normal open switch (KT10), air inlet fan (2), normal open switch and the second normal open switch (KT12) form loop to the negative pole of external power source, compared with before, the sense of current now flowing through air inlet fan (2) changes, therefore air inlet fan (2) reversion.And the operation principle of the second driver element (A3) is identical with the first driver element (A2), it is the location swap by each normal open switch and each normally closed switch, therefore when air inlet fan (2) is when rotating forward, air-out fan (3) is just in reversion, when air-out fan (3) air inlet fan (2) when reversing just is rotating forward, forever be operated in one to supply gas in cabinet, a pattern be vented outward toward cabinet.
With reference to the circuit theory diagrams of the control module (A1) shown in Fig. 2, a period of time has been rotated forward in air inlet fan (2), air-out fan (3) has reversed after the time of one end, very first time relay coil (KT1) adhesive, the first normal open switch (KT10) in response to very first time relay closes, now the second time relay Delayed conducting, in very first time relay work second time relay not operating during this period of time in, air inlet fan (2) rotates forward, air-out fan (3) reverses, and when the second time relay conducting, the 5th normally closed switch (KT21) in response to the second time relay coil (KT2) is disconnected, because the time relay is on-delay, power-off not time delay, so the first normal open switch (KT10) disconnects at once, make the also power-off of second time relay, thus the 5th normally closed switch (KT21) is closed again, the circuit state of control module (A1) has got back to initial condition again, controlling driver module makes regulator cubicle enter again air inlet fan (2) rotating forward, the mode of operation that air-out fan (3) reverses, by way of further example, if the time very first time relay of time delay 300s and second time relay of time delay 30s that the utility model is selected, after regulator cubicle powers on, air inlet fan (2) rotates forward, air-out fan (3) reverses, air-flow in regulator cubicle moves from lower to upper and carries out proper heat reduction, and when arriving the delay time of 300s, air inlet fan (2) is reversed, air-out fan (3) rotates forward, air-flow in regulator cubicle moves from top to bottom and will be deposited in the dust blowout of air inlet, after work 30 like this, again the heat radiation work entering 300s, then or the dedusting work of 30 seconds, so repeatedly, single airflow direction would not be only had like this, by arranging a woven cloths filter pad (5) of being comparatively altogether unjustifiable on air inlet and air outlet, dust enters in regulator cubicle with air-flow from various gap, also the problem of regulator cubicle poor heat radiation can not be caused because of air inlet Severe blockage.Time relay model of the present utility model is the western JSZ3F-24VDC of moral power, and concrete delay time is adjustable, and the model of fan is SNOWFAN-17251-DC24V-1.4A, and auxiliary relay model is OMRON-MY4NJ-DC24V.
The utility model is by arranging driver module, make air inlet fan and air-out fan cooperating in two kinds of mode of operations, driver module work is controlled by arranging control module, regulator cubicle inner air is flowed to so not single, avoid dust be adsorbed on for a long time on the filter screen in air port and cause air inlet to block, also solve the problem of regulator cubicle heat radiation.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
