Description
Technical field
The utility model relates to overhead transmission line porcelain insulator string state of insulation inspection device, be applicable to patrolling transmission line personnel ground inspection to be erected on shaft tower porcelain insulator string run in insulation situation.
Background technology
In high-voltage alternating overhead transmission line, the application of porcelain insulator string is quite extensive, the change of the leakage current of line porcelain insulator chain, the quality of the electric property of insulator can be reflected, with insulator surface contamination degree, also be the index that circuit operating management department is concerned about, in circuit operational management practice, the situation that the power frequency leakage current that usually there will be porcelain insulator string increases, its main cause: be the resistance value of in insulator chain certain 1 or multi-disc insulator be zero, the total resistance value of insulator chain is caused to reduce, make the deterioration of interior insulating property, or insulator surface contamination degree is higher, insulator is caused to be partially formed path along face, make external insulation hydraulic performance decline, make insulator chain overall insulation hydraulic performance decline, due to the overall insulation performance of insulator chain and interior, external insulation performance is relevant, now on the market, instrument without this type of breakdown judge is sold, make line inspection personnel on the ground, cannot grasp in time by the insulator chain state of insulation looked into.
Summary of the invention
Technical scheme of the present invention solves like this: the invention discloses overhead transmission line porcelain insulator string state of insulation inspection device, for exchanging overhead transmission line porcelain insulator string state of insulation inspection work, it is characterized in that, this device is by leakage current collecting unit, signal processing unit, wireless telecommunications transmitter unit, power supply unit, hand-held inspection instrument composition, wireless telecommunications transmitter unit (3) and hand-held are patrolled between instrument (5) and are connected by 33KHz wireless communication networks, professional is on the ground at tested insulator chain scene in inspection, by above-mentioned detection mode and equipment, realize patrolling to overhead transmission line porcelain insulator string state of insulation.This device 33KHz used wireless communication networks equipment price is cheap.
