Description

Full loop self check ac high-voltage electroscope

Technical field:

The utility model relates to a kind of ac high-voltage electroscope, particularly relates to a kind of full loop self check ac high-voltage electroscope.

Background technology:

Common employed ac high-voltage electroscope is though it also all has self-checking circuit, but this self-checking circuit is the direct current self-checking circuit, and, when carrying out self check, only self check testing circuit and indicating circuit, like this, there is fault if work as ac high-voltage electroscope probe or block isolating circuit, just can't grasp, so, will make used ac high-voltage electroscope can not play due effect, simultaneously, also can cause personal injury accidents.

Summary of the invention:

The purpose of this utility model is that a kind of improved full loop self check ac high-voltage electroscope will be provided, it not only can realize the full loop self check to the ac high-voltage electroscope effectively, guaranteeing that the ac high-voltage electroscope is using under fully normal situation, and, the generation of accident beyond also can preventing.

Solution of the present utility model to achieve the above object is: full loop self check ac high-voltage electroscope of the present utility model has sound and light display and multi-joint telescoping control lever, described sound and light display includes a housing and bonnet, leading section on the positive end face of described housing is provided with a full loop self check pilot lamp and under-voltage pilot lamp, middle part on the positive end face of described housing is provided with a self check button, the left part of the described housing upper end end face high voltage electroscope probe that has been fixedly connected, the right part thread connection of described housing lower end surface has a multi-joint telescoping control lever, the groove internal fixation of described housing bottom left end has one to detect pilot lamp and detect hummer, be provided with the circuit board of a band ground lug in the described housing, described circuit board is by block isolating circuit, testing circuit, indicating circuit and self-checking circuit are formed and are formed electrical connection, described block isolating circuit also forms with the end, lower end of described high voltage electroscope probe and is electrically connected, described self-checking circuit is for exchanging self-checking circuit, described self-checking circuit is by R1, R2, R3, R4, R5, R6, Q1, Q2, C1, C2, C3, D1, D2, D3, U1 and U2 form, the output terminals A of described self-checking circuit also forms with the end, lower end of described high voltage electroscope probe (8) and is electrically connected, and the bottom in the described housing is equipped with an electric battery storehouse.

Because the utility model has improved existing ac high-voltage electroscope, reform self-checking circuit into the interchange self-checking circuit by the direct current self-checking circuit, and the output terminal that makes self-checking circuit also forms with the end, lower end of high voltage electroscope probe and is electrically connected, thus, can implement the full loop self check to the ac high-voltage electroscope, and correctly ensure safe operation reliably.
