Abstract

The utility model discloses an all-loop electroscope. The all-loop electroscope, under the control of a main control unit, comprises a high voltage sampling circuit module, a sine wave voltage generator circuit module and a probe, wherein the high voltage sampling circuit module, the sine wave voltage generator circuit module and the probe are mutually connected in series; the probe is positioned at the top portion of the electroscope; one end of the probe is connected with one end of a line formed by that the high voltage sampling circuit module and the sine wave voltage generator circuit module are connected in series; and the other end of a line formed by that the other end of the probe, the high voltage sampling circuit module and the sine wave voltage generator circuit module are connected in series is used for connecting with a high voltage line. According to the all-loop electroscope, the probe is added to the all loop for performing detection. When the probe is in poor contact with the sine wave voltage generator circuit, the probe contact breaks off the all-loop circuit, and gives prompts that a fault happens to the electroscope, and thus occurrences of accidents caused by probe faults are prevented. The all-loop electroscope is suitable for the self-detection of alternating current electroscopes and the detection of alternating current high voltage circuits.

The utility model content
The technical matters that the utility model will solve provides a kind of full loop electroscope, and whether it also is included into probe and detects in the loop, can well detect probe and circuit contacts, the generation of the mishap that can avoid causing because of the probe fault.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of full loop electroscope; The high pressure sample circuit module, sine voltage generator circuit module and the probe that under the control of main control unit, comprise mutual serial connection; Probe is positioned at the electroscope top, and the one of which end is serially connected with an end of the circuit that high pressure sample circuit module and sine voltage generator circuit module serial connection forms; The other end of the circuit that the other end of probe, high pressure sample circuit module and sine voltage generator circuit module serial connection form is used for linking with high-tension line.
As the qualification to the utility model, full loop also is serially connected with trigger circuit module and sound light alarming circuit module.
As the further qualification to the utility model, sound light alarming circuit module output terminal is serially connected with the undervoltage detection circuit module.
Owing to adopted technique scheme, the utility model compared with prior art, the technical progress that is obtained is: the utility model has improved existing full loop electroscope; Inserting probe is the part in the full loop; During detection, when probe and the loose contact of sine voltage generator circuit, the probe contact point can break off the full loop circuit; The prompting electroscope breaks down, the generation of the mishap of having avoided causing because of the probe fault.
The utility model is applicable to that self check of ac high-voltage electroscope and ac high-voltage circuit detect.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Fig. 1 is the utility model one-piece construction functional block diagram.
Among the figure: 2, high pressure sample circuit module; 3, trigger circuit module; 4, sound light alarming circuit module; 5, under-voltage testing circuit module; 6, sine voltage generator circuit module; 7, probe; 8, high-tension line.
Embodiment
Embodiment
The content of present embodiment relates generally to galvanoscopic circuit part; Galvanoscopic concrete structure is identical with existing electroscope; Like casing for electric appliances, self check pilot lamp, under-voltage pilot lamp, self check button and multi-joint telescoping control lever etc., all belong to content of the prior art, repeat no more at this.The circuit part content that only present embodiment is related to is below narrated.
As shown in Figure 1; The full loop electroscope of present embodiment comprises sine voltage generator circuit module 6, high pressure sample circuit module 2, trigger circuit module 3, sound light alarming circuit module 4, undervoltage detection circuit module 5 and the probe 7 of mutual serial connection under the control of main control unit.
