Abstract

The invention discloses a cascade high-potential energy supply device, which comprises an iron core and an insulating cylinder, wherein an insulator is formed by winding the periphery of the iron core so that the iron core has a fully-insulated structure; a primary winding and a secondary winding are respectively arranged at the upper and lower ends of the insulator and respectively provided with a wire-outgoing sleeve which leads a wiring terminal out; and the iron core, the insulator, the primary winding and the secondary winding are fixed in the insulating cylinder. By adoption of the insulator, potential isolation between the primary winding and the secondary winding is realized, so that the primary winding and the secondary winding are totally positioned on a high-voltage side or a low-voltage side. By adoption of the insulating cylinder, the cascade high-potential energy supply device can be isolated from external potential. The cascade high-potential energy supply device can be arranged between a high-voltage part of an on-line monitoring device and a mains supply, so the problem about power supply for the high-voltage part of the on-line monitoring device is solved.

Description

technical field [0001] The invention relates to electric equipment, in particular to a cascaded high-potential energy supply device. Background technique [0002] The prior art solves the energy supply problem by installing an online detection device at the high potential of the main equipment. Installing online monitoring devices on high-voltage electrical equipment can monitor the status of electrical equipment in real time, and achieve early detection, early warning and early treatment of equipment failures to avoid developing into malignant accidents, which is one of the important measures to improve the reliability of equipment operation. When the online monitoring device is running, it is often necessary to collect and convert data in the high-voltage part of the high-voltage electrical equipment. Due to the problem of high-voltage and low-level potential isolation, it cannot be directly powered by the mains power supply. The energy supply of the acquisition and conve...
