The electroscope of production, and safeguarding than electroscope very complicated, onsite application is extremely inconvenient or even certain power frequency high voltage generators itself
There are security risks, cannot control the overall process of electroscope electrical verification, leave security risk to work on the spot, may result in electrical verification
The erroneous judgement of operating personnel even jeopardizes the personal safety of electrical verification operating personnel, causes irremediable loss.
Invention content
The purpose of this utility model is to solve said one or multiple defects, designs a kind of electroscope with self-checking function.
To realize the above goal of the invention, the technical solution adopted is that：
A kind of electroscope with self-checking function, the electroscope include shell, contact electrode, connector, inspecting electrode, electricity
Road plate, buzzer, indicator light and power supply；Wherein inspecting electrode is mounted on the upper surface of shell, the top of inspecting electrode and connection
The bottom end of body connects, the top connection contact electrode of connector；Circuit board, buzzer, indicator light and power supply are all provided with inside the shell
The installation of portion, wherein circuit board inside the housing install on circuit boards by top, buzzer, indicator light, and power supply is buzzer and refers to
Show that lamp is powered.
Preferably, the shell is the shell of cube structure.
Preferably, the shell is the shell of isolation material.
Preferably, the connector be can slide up and down structure, can make when connector upward sliding contact electrode and
Inspecting electrode is connected.
Further, the power supply is button cell, and wherein button cell outer surface setting button cell box is to button electricity
It is installed in pond.
Compared with prior art, the beneficial effects of the invention are as follows：
1) the utility model has the function of totally self-checking, can detect all circuits and the whether normal work of element inside electroscope
Make, the alternative test on charging equipment and the project tested with power frequency high voltage generator, it is ensured that the peace of electroscope field application
Full reliability；
2) when the normal electrical verification of the utility model, contact electrode contacts high voltage electrical body, and the electricity of very little is flowed into electroscope
Stream, this low current amplify through amplifier and trigger electronic loop judgement；
3) when carrying out self-test to electroscope, contact electrode is connected with inspecting electrode, using high voltage equivalent circuit theory, phase
It is contacted with high voltage electrical body when in contact electrode, different electric signals has been input to the same electronic loop and has judged, i.e. self-test
All it is to identify that is walked is same path, to reach totally self-checking by same circuit judges from contact electrode input with electrical verification
Purpose.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
Below in conjunction with drawings and examples, the present invention is further elaborated.

Battery is installed.
When the normal electrical verification of the utility model, contact electrode 4 contacts high voltage electrical body, and the electricity of very little is flowed into electroscope
Stream, this low current amplify through amplifier and trigger electronic loop judgement；When the utility model carries out self-test to electroscope, contact
Electrode 2 is connected with inspecting electrode 4, using high voltage equivalent circuit theory, is equivalent to contact electrode 4 and is connect with high voltage electrical body
It touches, different electric signals has been input to the same electronic loop and has judged, i.e. self-test and electrical verification is passed through from contact electrode input
Same circuit judges identification, what is walked is same path, to achieve the purpose that totally self-checking.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
