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.

Description

The full loop electroscope

Technical field

The utility model belongs to power domain, relates to a kind of ac high-voltage electroscope, specifically relates to a kind of full loop electroscope.

Background technology

The ac high-voltage electroscope all has self-checking circuit;, electroscope can comprise that high pressure sample circuit, trigger circuit, sound light alarming circuit, undervoltage detection circuit, sine voltage generator circuit carry out fault detect before using, to judge that can the circuit in the loop operate as normal to its loop.Galvanoscopic upper end has probe, is used for surveying the contact high voltage magnetic field.The output terminal of sine voltage generator circuit forms with the probe lower end and is electrically connected.There is not detector probe whether good during the electroscope self check in the prior art with contacting of circuit; If probe contacts bad with the detection loop; Show normal even if electroscope detects the loop; Also can influence the judgement of electroscope, still can not thoroughly avoid the generation of accident high-tension apparatus or electric line fault detect.

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.
