SU457048A1 - Insulator bar for insulators under voltage - Google Patents

Description

one

This invention relates to the field of electrical engineering.

Bars are known for controlling insulators that are under voltage, containing a spark gap, a capacitor connected in series with a lower meter, two electrodes and an insulating portion of screwed tubes.

To improve the reliability of test results and performance when rejecting insulators in the proposed rod, the capacitor is made in the form of a hollow dielectric tube, inside which an adjustable spark gap is enclosed, parallel to the capacitor, a removable light indicator, a neon light bulb, and electrodes are cut, notched.

The insulating part of the rod is made of portable tubes, the number of which is dialed by voltage, which makes it possible to test insulators at different voltages.

The drawing schematically shows the head described shtangi.

The rod consists of a condenser head made of a hollow dielectric tube 1, for example of vinyl plastic, with a closed opening on one side and an adjustable spark gap 2 enclosed inside a high-voltage lightweight protective capacitor with a voltage of 35 kV, clamp 3, which is intended to be attached to the rod (it the outer capacitor plate), a collar 4 for fastening the folding electrodes 5, which is at the same time the base for the screw with which it regulates with a spark gap 2 when testing insulators, a nut 6 fixing the spark gap, a bolt with a nut 7 for fastening the electrode and leading the light bulb 8. The light bulb 8 is connected parallel to the capacitor through the spark gap. The insulating part is made of screwable dielectric tubes that enter the top to the bottom, for example fiberglass.

The testing of isolators using the described rod is based on the determination of the voltage on the gluing of an insulator or a wire element. A working element when applying electrodes 5 inside the head itself can hear a buzzing (buzz) emitted by a spark when the spark gap is operating,

different from the crown, and directed into the open hole. The sound at the same time is amplified, the light bulb 8 lights up, that at low voltages on the insulator. With "zero defective isolator, the buzz is not audible and

the light does not shine. Spark reduction

span 2 screw gives the final result.

The boom can also be used to check the absence of voltage on power lines.
