Abstract
The invention relates to an insulating property online monitoring device for an electronic transformer. A signal collecting screen is additionally arranged in an existing insulating structure of the electronic transformer. Collected signals are outputted to a signal processing unit, the processing unit carries out filtering, tuning and amplification processing on the collected signals, effective signals are transmitted to the background, and an alarm and protection action is started, thereby ensuring the reliability of the complete machine of the electronic transformer, and ensuring a power grid to be safe and reliable.
Description
Technical field
The present invention relates to a kind of insulating property on-Line Monitor Device for electronic mutual inductor.
Background technology
Intelligent grid is the developing direction of electrical network, and wherein, intelligent substation is the core link of intelligent grid, and electronic mutual inductor then is the infrastructure device of intelligent substation.Present electronic mutual inductor is emerging product, and a lot of advantages are arranged on the performance, but the horizontal disunity of market product, and wherein insulating property are uneven, cause at the scene hanging net operation process intermediate frequency to have explosion accident to produce, and have certain potential safety hazard.Be directed to SF6 gas or oil-insulated electronic mutual inductor, the insulativity on-line monitoring technique is that safe operation of electric network ensures reliably.Yet present insulating monitoring technology also rests on artificial off-line monitoring state, and complicated operation has brought very big difficulty to maintenance.
Summary of the invention
The purpose of this invention is to provide a kind of insulating property on-Line Monitor Device for electronic mutual inductor, in order to solve the problem of off-line monitoring complicated operation.
For achieving the above object, the solution of the present invention is: the insulating property on-Line Monitor Device that is used for electronic mutual inductor, the insulation system that comprises electronic mutual inductor, a signals collecting screen suspend to be installed in the insulation system of electronic mutual inductor, and the signals collecting screen is connected to the signal processing unit outside the insulation system of electronic mutual inductor by signal transmssion line.
Described signals collecting screen is a metal cylinder, and insulating mounting is on fairlead.
The insulation system of described electronic mutual inductor is gas/liquid insulation column formula structure.
The axis coaxle setting of described fairlead and insulation column.
Insulating property on-Line Monitor Device for electronic mutual inductor of the present invention; increase signals collecting screen in present electric mutual inductor insulation system; gather signal and export signal processing unit to; treated unit filtering, tuning, amplify to handle after; useful signal transfers to the backstage; start and report to the police and the protection action, thus the reliability of assurance electric mutual inductor complete machine, thus guarantee the safe and reliable of electrical network.
Description of drawings
Fig. 1 is the insulating property on-Line Monitor Device structural drawing for electronic mutual inductor of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
