Abstract

The invention relates to an overhead transmission line power pickup device and method. The overhead transmission line device comprises an inductive charge aggregation device, a charge aggregation gap discharge device and a transformer; one terminal of the charge aggregation gap discharge device is connected to the inductive charge aggregation device, and the other terminal of the charge aggregation gap discharge device is connected to a high voltage terminal of the transformer; a primary side of the transformer is connected to the ground; a secondary side of the transformer is connected to a load; the charge aggregation gap discharge device has a gas gap; the inductive charge aggregation device inducts and aggregates the charges in an electromagnetic field of the overhead transmission line; the charges aggregated by the inductive charge aggregation device intermittently breaks down the gas gap of the charge aggregation gap discharge device to form pulse current; and the pulse current is outputted to the load after regulation by the transformer. When being used for a non-contact online monitoring device, the overhead transmission line power pickup device and method can guarantee a non-contact online monitoring device to operate safely and stably.

Description

technical field

[0001] The invention relates to the technical field of power grids, in particular to a device and method for taking power from an overhead transmission line. Background technique

[0002] On the overhead transmission wire, an online monitoring device is generally installed on the line tower to monitor the transmission wire online. In order to ensure that the online monitoring device can be used for a long time, the power supply of the online monitoring device becomes a main problem affecting the available time of the online monitoring device. Although wireless power transfer (WPT) methods (respectively, inductive coupling, near-field resonance and microwave radiation) are widely used in small electrical equipment such as mobile phones and electric toothbrushes, but through the above-mentioned inductive coupling, When the three methods of near-field resonance and microwave radiation are used to supply power to online monitoring equipment, it is necessary to h...
