Abstract
The utility model discloses an overvoltage surge current tester for a secondary system of a transformer station. The overvoltage surge current tester comprises an electronic lightning stroke counter and a thunder peak value tester, wherein the ground wire of the surge protector is connected to the induction coil of the electronic lightning stroke counter, and a grounding lead of a lightning protection device is connected to the test magnetic card of the thunder peak value tester. The overvoltage surge current tester solves the problem of a conventional secondary system of a transformer station, where the principle of voltage forming in the transformer station and actual situation of surge current generation remain unknown, no scientific foundation is provided, and devices are damaged by lightning strokes due to useless lightning protection measures and delayed overvoltage-and-lightening-proof work for the secondary system of the transformer station.

The beneficial effects of the utility model:
The utility model is mounted with lightning protection device and Surge Protector on the transformer station secondary system loop, inductive coil by the ground wire of Surge Protector access electronics lightning stroke counter, on the test magnetic card of lightning protection device down conductor access thunder and lightning peak value test device, by the data that gather in electronics lightning stroke counter statistics certain hour, can grasp the superpotential production at substation secondary device distribution line place, by electronics lightning stroke counter and lightning current peak value test device, lasting detection by one or several thunderstorm season, by the data that detect, can estimate objectively the thunderstorm actual conditions of transformer station, definite foundation that provides for the lightning protection grade of the Lightning Strike Risk Evaluation of transformer station and transformer station secondary system equipment, solved current transformer station secondary system owing to can't knowing that superpotential is in the mechanism of transformer station's formation and the actual state that produces surge current, there is no rigorous science data is foundation, and lightning protection measures is seemed, and blindness and equipment anti-overvoltage and the anti-lightning strike work hysteresis that causes transformer station secondary system that do not gear to actual circumstances often cause equipment by problems such as broken by lightnings.
The accompanying drawing explanation:
Fig. 1 is the utility model test philosophy schematic diagram.
Embodiment:
A kind of transformer station secondary system overvoltage surge current testing device; it comprises electronics lightning stroke counter and thunder and lightning peak value test device; by the inductive coil of the ground wire of Surge Protector access electronics lightning stroke counter, by the test magnetic card of lightning protection device down conductor access thunder and lightning peak value test device.
Surge Protector is arranged on transformer station secondary system equipment distribution line.
Lightning protection device is arranged on substation secondary observing and controlling loop, and secondary observing and controlling returns to comprise the secondary observing and controlling loops such as interchange, direct current, communication and voltage transformer (VT).
Thunder and lightning peak value test device comprises test magnetic card and magnetic card reading apparatus, and the test magnetic card is a kind of peak point current sensor.Electromagnetism bar on the test magnetic card has special coding, because every live wire can produce magnetic field, the size of this magnetic field intensity and current in wire value has funtcional relationship, thereby electromagnetism bar coding can be controlled in this magnetic field, the magnetic card reading apparatus is a kind of reading device, be used for identifying the electromagnetism bar coding on magnetic card, thereby draw the peak value of lightening pulse electric current on transformer station secondary system equipment.
The electronics lightning stroke counter is the number of times of recording power with the Surge Protector electric discharge; whether its effect is on the equipment distribution line of monitoring substation electrical secondary system, to have superpotential to produce; and whether the Surge Protector of installing on circuit plays the effect of lightning protection; and the total degree that produces and protect action; by the data that gather; can grasp the superpotential production at substation secondary device distribution line place, reflect objectively actual conditions.
