Abstract
The invention discloses an insulator fault detector, which comprises a clamp claw, wherein a semicircular groove is arranged on the clamp claw, an arc-shaped rack is arranged in the semicircular groove, both ends of the arc-shaped rack are provided with ultrasonic wave probes, the arc-shaped rack is engaged with a gear, the gear is connected with a motor, a power supply of the motor is taken from the voltage on a high-voltage cable, in addition, a switch control circuit is arranged on the motor, and the switch control circuit is connected with a remote control center. After the adoption of the technical scheme, the motor is controlled by the remote control center, so the fault of the insulator can be detected in a remote distance, and a large amount of labor and materials can be saved.
Description
Technical field
The present invention relates to a kind of machinery that support insulator circumferentially detects that is used for, relate in particular to a kind of can the realization and accomplish the electrical insulator fault detector that detects around the axle motion automatically.
Background technology
In recent years, electrical network mesohigh pillar porcelain insulator fractureed, and CRACKING ACCIDENT frequently takes place, and brought serious harm for the normal operation and the life safety of electric system.For this reason, various countries Utilities Electric Co. has proposed necessary reinforcement operation maintenance management, has guaranteed the requirement of high-voltage strut porcelain insulator safe operation, and required the high-voltage strut porcelain insulator is carried out general census.
Research shows, the joint portion that the stressed worst position of support insulator is cast iron flange and porcelain knob, and all phenomenon of ruptures also almost all appear at this position.Utilize the UT (Ultrasonic Testing) technology can effectively detect the defective that this position exists.And ultrasonic detection technology is unique effective ways of finding high-voltage strut insulator crackle at present.The scientific and technical personnel of Sichuan Electric Power Testing Inst. explore through great efforts; Different characteristic to insulator inside and surface imperfection; Adopted corresponding ultrasonic probe; Utilize ultrasound wave compressional wave oblique incidence technology and climb wave technology support insulator flange faying face is detected a flaw comprehensively, obtained desirable flaw detection effect.Obtaining on the basis of practical experience, we promote this technology in the scope of full river, and hope can be eliminated the existing potential safety hazard of Sichuan Electric Power System support insulator, guarantees the safe operation of Sichuan Electric Power System.
