The utility model has the advantages that people can do other work in the waiting time before the contact conduction or switching-off of the warning device for improving the work efficiency.
Description
Technical field
The utility model relates to a kind of device that electric contact conducting or off-state are reported to the police, be particularly related to a kind of main-transformer body pressure type temperature controller that is applicable to, in testing laboratory's verification to its control contact on setting valve calibration or when debugging the break-make situation main transformer body pressure type temperature controller connection point on-off alarm of pointing out.
Background technology
Pressure type temperature controller in the thermal meter (hereinafter to be referred as tested table), its heating-up temperature rising (or decline) is very slowly when verification.About the conducting or the disconnection of the rising of instrument indicator pointer or decline, electric contact, stipulate that Huan's temperature groove temperature changing speed should be greater than 1 ℃/min among the inspection procedure JJG310-2002.The temperature rise speed of actual Huan's temperature groove also is less than 1 ℃/min.Near desired value the time, its temperature rise speed is just slower, so that when making pointer near desired value, is unlikely to delay the time that pointer is stabilized in desired value because the cause of thermal inertia is too gone out desired value.The control contact of tested table has three pairs usually, and the pair of control fan starts automatically, and two pairs are sent the too high and superelevation signal of oil temperature (or winding) temperature respectively in addition.Tested table rises to the contact conducting from temperature, disconnects from being conducting to contact again, and the return difference value of temperature is (5～7) ℃ (different microswitch return difference value difference) approximately, and three docking point rise and fall do not include at least six of contact adjustment back and forth.Because tested table needs to wait for long time, inefficiency in check and electric contact calibration or debugging.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of being to increase work efficiency, and avoids the main transformer body pressure type temperature controller connection point on-off alarm of detected table boring wait in checking procedure.
A kind of main transformer body pressure type temperature controller connection point on-off alarm, its structural feature is: comprise the break-make warning circuit and be used to be provided with the box body of warning circuit, box body surface is provided with binding post, beacon lamp and on-off switch.Described break-make warning circuit comprises power supply, one often opens a normally closed relay state exchange contact, electroacoustic transducer, loudspeaker, one logical one disconnects the pass, described relay is connected in the two poles of the earth of power supply, on the circuit at the operating voltage coil two ends of relay, be serially connected with and be used for the binding post that is connected with tested table contact lead, coil two ends at relay are parallel with light-emitting component and current-limiting resistance thereof, between the two poles of the earth of power supply, also be provided with normally-open normally-close contact by relay, the on-off switch contact, the circuit that the electroacoustic transducer serial connection forms, for to be parallel between the two poles of the earth of power supply, loudspeaker is connected with electroacoustic transducer between this shunt of electroacoustic transducer and the relay shunt.
During use, tested table contact lead is connected with the alarm binding post, when contact conducting or disconnection, sends the bright prompting of alarm sound and lamp.Because temperature variation is slow, can not cause reading error in time to the setting value reading during warning.In the contact conducting or in the stand-by period before disconnecting warning, can do some other work, to improve the efficient of work.
Described power supply is a battery.
Described loudspeaker is a Microspeaker.
Described relay is a midget relay.
Described light-emitting component is a light emitting diode.
Described electroacoustic transducer is the electronic door bell chip.
In sum, this pressure type temperature controller connection point on-off alarm has following advantage:
1, in the check of the contact definite value of oil temperature table and winding temperature table, can save the plenty of time, be used for other affairs.
2, the alarm size is little, and is easy to use, and selection is made simple easily.
3, need not safeguard two joint #
5Battery can use 2 years.
4, the action of thermometer contact (leading to) and return (breaking) only needs to operate connection point on-off alarm switch K once.

Fig. 1 is the utility model main transformer body pressure type temperature controller connection point on-off alarm circuit figure
Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Embodiment 1
A kind of main transformer body pressure type temperature controller connection point on-off alarm as shown in Figure 1, comprises the break-make warning circuit and is used to be provided with the box body of warning circuit that box body surface is provided with binding post, beacon lamp and on-off switch.Described break-make warning circuit comprises power supply, one often opens the state exchange contact of a normal close minisize relay, electroacoustic transducer, Microspeaker, one logical one disconnects the pass, described relay is connected in the two poles of the earth of power-supply battery, on the circuit at the operating voltage coil two ends of relay, be serially connected with and be used for the binding post that is connected with tested table contact lead, coil two ends at relay are parallel with light-emitting diodes light and current-limiting resistance thereof, between the two poles of the earth of power supply, also be provided with normally-open normally-close contact by relay, on-off switch, the circuit that the electroacoustic transducer serial connection forms, for to be parallel between the two poles of the earth of power supply, loudspeaker is connected with electroacoustic transducer between this shunt of electroacoustic transducer and the relay shunt.Electroacoustic transducer is the electronic door bell chip.
The principle of work of the contact of this main transformer body pressure type temperature controller connection point on-off alarm is summarized as follows:
In the contact definite value of pressure type thermometer calibration (or adjusting the back), when temperature slowly rises, when contact WD connects:
2, power supply "+" utmost point → relay J
1Closed (J
2Disconnect) → on-off switch K
1-3→ electroacoustic conversion DS → power supply "-" utmost point, loudspeaker YS audible alarm.Behind the YS audible alarm, K pulls to K with on-off switch
2-3Position (sound involution), the temperature value when noting simultaneously the contact action rapidly.At this moment, the connection point on-off pilot lamp still lights, and the prompting contact is also in on-state.
Operation calibration cell temperature controller descends temperature toward low temperature, after contact WD disconnects:
1, obstructed between power supply "+" → m, the n binding post → pilot lamp D breath go out → the relay J dead electricity returns.
2, power supply "+" utmost point → relay tip J
2Closed (J
1Disconnect) → K switch
2-3→ electroacoustic transducer DS → power supply "-" utmost point.Loudspeaker sounds once more, the rreturn value when this moment, verification worker should be noted the contact disconnection rapidly.
It is same as the prior art that present embodiment is not stated part.
