Its advantage lies in: 1, simple structure has kept luminous low pressure to test the structure of electrography, has only increased special buzzer on the basis of original structure, 2, need not install the battery, utilize measured object institute to make the buzzer send audible alarm with electricity.
Description
Technical field
The utility model relates to the technical field of low pressure electrical verification, and concrete is to carry out on the basis of luminous low pressure electroscopeImproved technical scheme, particularly its connecting structure for electrical equipment.
Background technology
In life, people be unable to do without electricity, TV, computer, refrigerator, air-conditioning, washing machine, electromagnetic oven, mobile phone etc. nowDeng, the life of these electrical equipment let us is very convenient. In factory, most explained hereafter equipment all will be used electricity, abilityMake to produce and normally carry out. But meanwhile, electricity is to cannot see impalpable tiger, everybody fears, in live and work, accidentallyCan there is Danger Electric shock risk, even threat to life. Therefore, people touching may be charged and jeopardize personal safety these equipment itBefore, whether chargedly will detect low pressure conductor or electrical equipment shell etc. with low pressure electroscope. But, present luminous low pressureElectroscope structure is to be in series by test contact, current-limiting resistance, neon tube, metal spring and hand touched electrode. By test contact withMeasured object contact, staff contact hand touched electrode, in the time that measured object has high voltage relative to the earth, neon tube starter, represents testedThing is charged. But, when observing neon tube in the bright direction of light whether when build-up of luminance, be not easy to see clearly, or neon tube fault is notWhen bright, easily cause the uncharged erroneous judgement of measured object, thereby bring Danger Electric shock risk.
Summary of the invention
The purpose of this utility model is to provide a kind of electroscope with sound alarm function, increases a special buzzingDevice, in the time that low pressure electroscope contacts with charged measured object, neon tube build-up of luminance is lighted, and buzzer ring is reported to the police simultaneously, at this moment, evenNeon tube fault or whether light because the reason of light does not see Chu's neon tube, also can judge measured object by the sound of buzzerCharged, avoid erroneous judgement to bring Danger Electric shock risk. Low pressure electroscope of the present invention itself does not need battery as working power,Only need to be at the other in parallel special buzzer of neon tube, utilize that measured object institute is charged makes the buzzer warning of sounding.
To achieve these goals, the technical solution of the utility model is: a kind of electroscope with sound alarm function, itsBe characterised in that: comprise a low pressure electroscope body, in the cavity of a low pressure electroscope body, be provided with a current-limiting resistance, current-limiting resistanceOne end props up one end of neon tube, and the other end of neon tube props up metal spring one end, and the metal spring other end props up one of buzzerEnd, the other end of buzzer is connected with hand touched electrode, and the front end of a low pressure electroscope body is provided with a test contact, this test contactOne end be connected with the other end of above-mentioned current-limiting resistance, the other end of test contact is hanging shape, hand touched electrode is arranged at low pressureThe rear end of an electroscope body, above-mentioned neon tube, metal spring, buzzer are all positioned at the cavity of a low pressure electroscope body.
The utility model discloses a kind of electroscope with sound alarm function, its advantage is: 1, simple in structure, keepThe structure of luminous low pressure electroscope, only on the basis of original structure, increased special buzzer; 2, do not need to install electricityPond, utilizes that measured object institute is charged makes the buzzer warning of sounding.
