Micro voltage generator for detecting working condition of electroscope

Abstract

The invention relates to a micro voltage generator for detecting the working condition of an electroscope. The micro voltage generator is characterized by comprising a battery, wherein the two ends of the battery are connected with a sine wave generating circuit so as to supply power to the circuit; the output end of the sine wave generating circuit is connected with the input end of a signal amplifying circuit; the output end of the signal amplifying circuit is connected with the primary side of a step-up transformer B; and the secondary side of the step-up transformer B is led out through a wire to serve as two detection terminals. The micro voltage generator of the invention is portable and small, works reliably, does not cause any harm to human body even in direct contact, completely meets the safe and reliable working needs and achieves the effect of safely, conveniently and reliably detecting the electroscope.

Description

technical field [0001] The invention relates to a miniature voltage generator for detecting the working condition of an electroscope. Background technique [0002] In electric power production, it is often necessary to carry out electric inspection on users, substations and outdoor high and low voltage live lines and equipment. According to the regulations of electric power production, the working condition of the electroscope should be tested before the electric inspection. At present, the electroscope is usually detected through other live equipment and live lines in operation, and at the same time, it is detected through the detection circuit of the electroscope itself. There are certain problems in these two kinds of detection. First, the sound and light self-testing circuit of the electroscope cannot fully prove the integrity of the working condition of the electroscope; secondly, if there are no other live lines and equipment nearby when working in the field, often It...

Problems solved by technology

There are certain problems in these two kinds of detection. First, the sound and light self-testing circuit of the electroscope cannot fully prove the integrity of the working condition of the electroscope; secondly, if there are no other live lines and equipment nearby when working in the field, often It brings difficulties to the inspection of electroscopes. At the same time, other live equipment and lines are used for inspection, which is dangerous to equipment and personnel.
