Problems solved by technology

[0003] Based on the difference of power supply, the current high-voltage power acquisition methods mainly include capacitor voltage division and conventional PT power acquisition. Among them, the capacitor voltage division power acquisition has low power and low power extraction efficiency, and the conventional PT energy acquisition has a large volume and is easy to damage due to resonance.

Abstract

The invention discloses a high-voltage electricity taking unit. The high-voltage electricity taking unit comprises a high-voltage transformer; the two ends of the primary side of the high-voltage transformer are connected with two high-voltage capacitor strings respectively; the high-voltage capacitor strings are connected with two phase lines respectively; the secondary side of the high-voltage transformer is connected with an electricity taking circuit in parallel. Meanwhile, the invention discloses a corresponding high-voltage electricity taking device. High-efficiency and high-power electricity taking can be achieved, the resonance probability can be greatly reduced, damage is not likely to happen, and meanwhile the size of the device can be greatly reduced.

Description

technical field [0001] The invention relates to a high-voltage power-taking unit and a device applied to a distribution network, belonging to the field of power-taking of the distribution network. Background technique [0002] With the rapid development of power distribution technology in my country in recent years, the requirements for the stability of power supply for power equipment in distribution network are getting higher and higher. The power supply mainly includes electromagnetic voltage transformers, electronic voltage transformers and capacitive voltage dividing equipment. Electromagnetic voltage transformers are prone to ferromagnetic resonance overvoltage, which will cause the voltage transformer to burn out. Electronic voltage transformers are currently mostly used as power supplies for high-voltage power grid line equipment, and are rarely used in distribution networks, with low cost performance. Capacitive voltage divider power-taking equipment divides volta...
