Abstract

The present invention discloses a 10kV power distribution tower grounding impulse response curve testing device which comprises an impulse current wave generation module, a dual-channel transient voltage waveform collection module for collecting a transient response voltage waveform, a data analyzing and processing module which is connected to the dual-channel transient voltage waveform collection module and is used for drawing an impulse response curve according to the collected transient response voltage waveform, a data storage module which is respectively connected to the dual-channel transient voltage waveform collection module and the data analyzing and processing module and is used for storing the transient response voltage waveform and the impulse response curve, a data transmission module which is connected to the data storage module and is used for transmitting the data stored in the data storage module, and a client which is respectively connected to the impulse current wave generation module and the data transmission module. According to the 10kV power distribution tower grounding impulse response curve testing device, in the condition of no power cut and no tower grounding excavation, the grounding characteristic of the tower grounding in a lightning surge or transient short-circuit fault condition can be obtained.

Description

technical field [0001] The invention relates to the field of testing the grounding network of a power system, in particular to a testing device for the grounding impact response curve of a 10kV power distribution tower. Background technique [0002] The grounding of 10kV power distribution tower is an important facility to ensure the safe operation of the tower and its electrical equipment. Especially in the case of lightning strikes, since the grounding device is buried underground, the grounding body is often thinned or even broken due to years of soil corrosion, and it may also be stolen. At present, the detection of the grounding performance of 10kV distribution towers in engineering is generally judged indirectly by measuring the power frequency grounding resistance with a shaking meter, but it is impossible to understand the characteristics of the lightning impact condition, that is, the transient short circuit. This makes the operation and maintenance personnel meet ...
