Problems solved by technology

The above two energy harvesting devices have the following disadvantages: 1. Due to the large number of uses, the installation mechanism needs to be designed separately in structure, and the fixing method is relatively cumbersome
2. The cables must pass through the centers of all energy-taking devices in turn. The size of the center hole of the device must be strictly controlled, and t

Abstract

The invention discloses an integrated energy extracting device for power electronic equipment. The device comprises a current transformer (1), a cable fixing unit (2), primary side terminals (3) and a transformer (10), wherein at least one cable fixing unit (2) is fixed on the current transformer (1) through screws, and two primary side terminals (3) are arranged at two ends of the current transformer (1) respectively and connected with the transformer (10) through cables. The device mainly supplies working energy for a trigger board (TE board) working with a high potential, and is provided with superior electrical and mechanical properties, simple in structure and easy to implement.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an integrated energy harvesting device for power electronic equipment. Background technique [0002] The TSC thyristor valve of the static var compensation device (SVC) needs to be triggered at the zero-crossing point of the thyristor voltage for the first time, and after being turned on, the reverse thyristor should be triggered to keep the capacitor connected to the system after the current zero-crossing point is naturally turned off. Therefore, the high-potential trigger board (TE board) mostly uses external energy supply, that is, adopts the current energy delivery method, and takes the current of a separate low-voltage system as the source of energy for the thyristor to start. The energy transmission system mainly includes energy transmission transformers and cables, and the energy harvesting part is mainly energy harvesting devices. In the existing scheme, the energy harvestin...
