[background technology]
Electroscope is a most basic most important security tool in the electric system work, electroscope is used for the high voltage electric equipment that needs interruption maintenance is carried out electrical verification at need installing ground wire place, when this place identifies the three-phase no-voltage, can install ground wire, have mutually as arbitrary, definitely ground wire can not be installed, charging cause must be found out.Other needs the place of electrical verification also can use electroscope.Therefore, it can guarantee proper operation and the personal safety in the electric system work.And the existing electroscope of electric system can not adapt to the power system development requirement, that this old-fashioned electroscope uses is inconvenient, directly perceived, be direct contact type, must directly contact high-pressure conductor and just can carry out electrical verification, to present power system development rapidly GIS equipment, installing the high-tension apparatus of insulating sheath additional and do not reveal the high-tension apparatus of conductor can't electrical verification.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of use directly perceived, convenient, but can directly not contact the just intelligent high-pressure electroscope of electrical verification of high-pressure conductor.
The utility model solves the problems of the technologies described above by following technological means: a kind of intelligent high-pressure electroscope, comprise scalability insulating bar and electroscope, described electroscope is installed in the front end of scalability insulating bar, described electroscope has a detecting head, described detecting head is positioned at galvanoscopic front end, described electroscope is a high voltage electroscope, described high voltage electroscope comprises detecting head, field effect transistor, triode, potentiometer, loudspeaker, the audio alert integrated circuit (IC) chip, switch, and power supply, wherein, the output terminal of detecting head is connected to the grid of field effect transistor, the drain electrode of field effect transistor is connected to the trigger end of first fixed contact and the audio alert integrated circuit (IC) chip of potentiometer simultaneously, second fixed contact of potentiometer and moving contact all are connected respectively to an end of loudspeaker and first end of switch simultaneously, the other end of loudspeaker is connected to the collector of triode, the base stage of triode is connected to the output terminal of audio alert integrated circuit (IC) chip, the source electrode of field effect transistor and the emitter of triode all are connected to the negative pole of power supply, second end of switch is connected to the positive pole of power supply, the cathode power supply end of audio alert integrated circuit (IC) chip is connected to first end of switch, and the negative power supply end of audio alert integrated circuit (IC) chip is connected to the negative pole of power supply.
Described power supply is the 3V direct supply.
The galvanoscopic advantage of the utility model intelligent high-pressure is: can carry out correct electrical verification to various situations, it is directly perceived, easy to use, but can directly not contact just electrical verification of high-pressure conductor.When the intelligent high-pressure electroscope carried out electrical verification to high pressure interruption maintenance equipment, not charged as the high pressure repair apparatus, the intelligent high-pressure electroscope did not send any audio alert sound.During when intelligent high-pressure electroscope contact or near the repair apparatus of electrification in high voltage, the intelligent high-pressure electroscope promptly continuously sends loud audio alert sound, and it is charged to remind the power system operation personnel to test high-tension apparatus.At this moment, high pressure repair apparatus charging cause is found out in the necessary shut-down operation of power system operation personnel, handles after ascertaining the reason.Carry out electrical verification after disposing again, can operate behind the true no-voltage of identification high-tension apparatus, thereby guarantee the electric system person and device security.
[description of drawings]
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
