Description
Technical field
It the utility model is related to high-tension electricity equipment corona monitoring field, more particularly to a kind of portable day of focus adjustable
Blind ultraviolet imagery device.
Background technology
Power system major part high-voltage electrical apparatus detection means external insulation structure has non-uniform electric field feature, extremely uneven
In electric field, after voltage is improved to certain value on gas gap, the very high passage of a conductibility can be formed in gap, claims gas
Gap breakdown.After breakdown, different discharge types is had according to power, electrode form, gas pressure etc., in low pressure, electricity
When source power is smaller, electric discharge shows as the aura full of whole gap or pulls out discharge of electricity form；Under high pressure, fire is often shown as
Flower, the electric arc even discharge type such as flashover；It in severe non-uniform electric field, can first start to discharge compared with strength in internal field, be referred to as
Corona discharge.Under normal operating conditions, its surface corona is weaker, and electromagnetic interference is small for high-voltage electrical apparatus detection means.But by
Defect, which occurs, in detection means surface in designing unreasonable, designing quality problem or affected by environment, and run can all cause
Electric field is concentrated and corona discharge occurs.For super-pressure, extra-high voltage electrical detection means, corona discharge feature is obvious, and thus
Bring the correlation effects such as radio interference, energy loss, noise pollution.
Corona（English is：electronic corona）, refer in more than 110kV electric substation and circuit, often
The discharging sound of " flight of steps leading to a palace hall mile " and nattier blue ring of light can be heard.Corona is specific electron avalanche --- streamer in severe non-uniform electric field
The stable discharging of form.The generation of corona is because rough conductor produces uneven electric field, in uneven electric field week
