Abstract

The invention discloses a device and a method for obtaining energy from a high voltage transmission line, and belongs to the technical field of high voltage technologies and power source technologies.The device comprises a high-voltage capacitor, a first-stage step-down transformer, a bidirectional thyristor module, a rectifier module, a filter capacitor, a voltage monitoring module, a thyristordrive module, a DC / DC voltage regulator module, an overvoltage suppression module and a shielding box. The principle of capacitance voltage division is employed, the high-voltage capacitor set is connected in series with the primary side of the transformer to effectively improve the output power of the device for obtaining energy, two-stage voltage reduction is employed to reduce the insulation design requirement of the transformer and reduce the size of the transformer. The wiring mode is flexibly configured between the high-voltage capacitor and the first-stage step-down transformer to achieve energy obtaining at a high level end between a phase and a ground and a low level end between the phase and the ground and between phase and phase, and the device and the method for obtaining energy from the high voltage transmission line can supply power for various electric devices.

Description

technical field [0001] The present invention relates to the intersecting fields of high-voltage technology and power supply technology, and more specifically, relates to a device and method for obtaining energy from a high-voltage transmission line. Background technique [0002] With the continuous expansion of power grid scale and the rapid upgrading of power grid automation technology, higher requirements are put forward for the intelligent level of operation and maintenance of transmission lines and substations. Obtain the operation data of transmission lines and substation main equipment through various online monitoring devices, and monitor their operation status in real time, which can provide decision-making basis for the intelligent operation and maintenance of the power grid, thereby promoting the development of this work and further improving the security of the power grid stable operating level. However, most of the on-line monitoring devices used for transmissio...
