6 connection insulated telescopic rods, electric power overhaul personnel hold insulated telescopic rods, and contacting construction portion by high-voltage probe 1 carries out electrical verification.It tests
Electric appliance enters sleep mode automatically state to economize on electricity when not in use, before use, push button 41, if infrared light transmission cover 5 appear light,
371 ring of the buzzer and visual window of light transmission 42 appears green, then electroscope can normal use carry out electrical verification operation, if infrared
Light shield 5 does not appear 371 non-ring of light or/and buzzer, then self-test is unsuccessful, and electroscope cannot use, if light transmission is visual
Window 42 appears red and then needs to change battery 2, and self-test must be carried out again after replacing battery 2.Outer casing base 5 is connected in inversion frustum
The small end of the infrared light transmission cover 5 of shape, when electrical verification, will not block the propagation of 22 sound of observation and buzzer of electrical verification result, be convenient for
The identification of electric power overhaul personnel.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the right of invention.
