Accompanying drawing explanation
Fig. 1 is the wiring diagram that temperature limiter of the present utility model detects frock one embodiment.
Embodiment
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, temperature limiter of the present utility model is detected to frock and be described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model and to be not used in restriction the utility model.
Be illustrated in figure 1 the wiring diagram that temperature limiter of the present utility model detects frock one embodiment.Whether this temperature limiter detects frock synchronous for detection of the bimetallic strip of temperature limiter and the action of contact, comprises fuse Fu, power light L1, K switch, the second pilot lamp L2, A.C. contactor KM, well heater Q2, thermal protector Q1 and telepilot.
Wherein, the coils from parallel connection of coils of A.C. contactor KM is at the two ends of power supply, after the contact cascade heater Q2 of A.C. contactor KM with the coils from parallel connection of coils of A.C. contactor.In test process, it is upper that the temperature-sensitive of temperature limiter is partly placed on well heater Q2, and well heater Q2 heats up for temperature limiter is forced, and makes the bimetallic strip action of temperature limiter, and A.C. contactor KM connects or disconnects for control heater.
Temperature limiter is electrically connected to telepilot, is provided with the first pilot lamp on telepilot, and the first pilot lamp is for showing being switched on or switched off of contact of temperature limiter.In the present embodiment, the power supply of telepilot for himself with battery, this battery is the first pilot lamp power supply.When bimetallic strip when action of temperature limiter, when tester hears temperature limiter, send " clickly " during sound, whether the first pilot lamp on observation telepilot synchronously extinguishes/light.If the first pilot lamp extinguishes/lights simultaneously, illustrate that temperature limiter is qualified; If first pilot lamp time delay a period of time extinguished/lights, illustrate that temperature limiter is defective.
By well heater, temperature limiter is forced to heat up, the mode of cooling, makes temperature limiter action or recovers naturally.Then with the bimetallic strip action of ear temperature limiter, send " clickly " sound, and observe extinguishing or lighting of the first pilot lamp simultaneously, judge that whether the bimetallic strip of temperature limiter and the action of contact be synchronous, guaranteed the accurate of temperature limiter performance, improved the reliability of temperature limiter.
As a kind of embodiment, thermal protector Q1 connects with the coil of A.C. contactor KM, for the overheating protection of well heater Q2.When the temperature of well heater surpasses the normal working temperature of well heater, thermal protector Q1 disconnects, and makes the coil blackout of A.C. contactor KM, and then the contact of A.C. contactor KM is opened, well heater Q1 power-off.More preferably, this temperature limiter detects frock and also comprises anti-guncotton, and anti-guncotton is arranged on the periphery of well heater Q2, for the protection of well heater.And, in well heater Q1 position, be provided with high temperature reminder flag.
As a kind of embodiment, after fuse Fu tandem tap K, be connected on the live wire L end of power supply, one end of fuse Fu connects the live wire L end of power supply, one end of other end connecting valve K; The other end of K switch connects overheat protector Q1.Wherein, fuse Fu is for the protection of whole circuit, and when the electric current of the fuse of flowing through surpasses normal value, fuse disconnects, and whole temperature limiter detects frock power-off.K switch comprises " opening " and " pass " two gears, for controlling this temperature limiter, detects the startup of frock or closes.When K switch is allocated to " opening ", stop detects frock and starts; When K switch is allocated to " pass ", stop detects frock and cuts out.
More preferably, power light L1 is connected in parallel on the two ends of power supply, and one end of power light L1 connects the corresponding common port of fuse Fu and K switch, and the other end of power light L1 connects the zero line N end of power supply.In the present embodiment, power light L1 is used for showing that this temperature limiter detects frock and whether switches on power.When power light L1 lights, illustrate that stop detects frock and switches on power; When power light L1 extinguishes, illustrate that this temperature limiter detects frock access failure power supply.
More preferably, the second pilot lamp L2 is in parallel with power light L1.One end connecting valve K of the second pilot lamp L2 and the corresponding common port of overheat protector Q1, the other end of the second pilot lamp L2 connects the zero line N end of power supply.Whether the second pilot lamp L2 is used for showing that this temperature limiter detects frock in running order, when the second pilot lamp L2 lights, illustrates that stop detects frock in running order.When the second pilot lamp L2 extinguishes, illustrate that stop detects frock and do not work.
The course of work that above-mentioned temperature limiter detects frock is as follows:
A, switch on power, observe power light and whether light.If power light is not lighted, deenergization, checks after circuit is fixed a breakdown and re-powers.Whether the first pilot lamp simultaneously detecting on telepilot normally works.
Whether, after b, power light are lighted, the switch that temperature limiter is detected to frock is allocated to " opening ", observe the second pilot lamp and light.If the second pilot lamp is not lighted, the switch that stop is detected to frock is allocated to " pass ", deenergization.Then, inspection circuit is fixed a breakdown, and opens the switch that stop detects frock after re-powering again.
After c, the second pilot lamp are lighted, well heater starts heating.Now, temperature limiter is connected on telepilot, and the temperature-sensitive position of temperature limiter is placed on well heater, well heater is heated temperature limiter.When hear temperature limiter send " clickly " sound, show that the bimetallic strip of temperature limiter moves, whether the first pilot lamp of simultaneously observing on telepilot synchronously extinguishes.
D, after the first pilot lamp extinguishes, temperature limiter is removed from well heater, make temperature limiter naturally cooling.When hear temperature limiter send " clickly " during sound, show that the bimetallic strip of temperature limiter restores to the original state, whether the first pilot lamp of simultaneously observing on telepilot is synchronously lighted.
The operation of e, repeating step c and steps d.
As in the repeatedly test process of temperature limiter, there is the nonsynchronous phenomenon of one-off in the bimetallic strip of temperature limiter and contact, shows that temperature limiter is defective.In at test process repeatedly, the equal synchronization action in the bimetallic strip of temperature limiter and contact, illustrates that this temperature limiter is qualified.
Temperature limiter of the present utility model detects frock, by well heater, temperature limiter is forced to heat up, and the mode of cooling, makes temperature limiter action or recover naturally.Then with the bimetallic strip action of ear temperature limiter, send " clickly " sound, and observe extinguishing or lighting of the first pilot lamp simultaneously, judge that whether the bimetallic strip of temperature limiter and the action of contact be synchronous, guaranteed the accurate of temperature limiter performance, improved the reliability of temperature limiter.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
