AI Technical Summary

Problems solved by technology

The spatial positioning of substations is generally based on UHF technology. Four or more antennas are used. The positioning results show the distance from each antenna. The work of implementing the positioning results on specific equipment requires manual search based on the positioning results. Not only is it very cumbersome, but it is also very easy to locate failures in equipment-intensive areas

Abstract

The invention discloses a transformer substation partial discharge space location device, which includes a plurality of antennas for partial discharge location. A cradle head which can adjust a rotational angle is arranged out of the antennas. A variable-focus camera is arranged out of the cradle head. The connection of the cradle head and the camera are controlled by an electronic computer. The transformer substation partial discharge space location device and method have the beneficial effects that the cradle head and the camera of which the rotational angle, an elevation angle, and the focal length are controlled by the electronic computer can automatically implement a location result, the whole process does not need manual intervention, the assistant location speed is fast and the accuracy is high.

Description

technical field [0001] The invention belongs to the field of power transformation and the field of measurement and testing at the same time, and specifically relates to a space positioning device and method for partial discharge in a substation Background technique [0002] There are many electrical equipment in the substation, once a failure occurs, it will lead to grid accidents and large-scale power outages, which will have a huge negative impact on the national economy and social stability. Statistics show that a considerable part of equipment failures are caused by the gradual development of internal partial discharges. At present, the spatial positioning of substation partial discharge has become an important task of substation inspection. The spatial positioning of substations is generally based on UHF technology. Four or more antennas are used. The positioning results show the distance from each antenna. The work of implementing the positioning results on specific...
