Outdoor integral intelligent combined transformer

Abstract

The invention discloses an outdoor integral intelligent combined transformer. The outdoor integral intelligent combined transformer is characterized in that a small current signal acquisition module acquires small current signals, a small voltage signal acquisition module acquires small voltage signals, a remote intelligent module receives the small current signals and the small voltage signals and outputs digital small current signals and digital small voltage signals, the current signal acquisition module acquires the small current signals by the aid of a Rogowski coil, the small voltage signal acquisition module acquires the small voltage signals by the aid of a capacitive voltage dividing ring and an inductive voltage divider, and epoxy resin is cast on the Rogowski coil, the capacitive voltage dividing ring, the inductive voltage divider and the remote intelligent module to form a transformer body. The outdoor integral intelligent combined transformer has the advantages that the outdoor integral intelligent combined transformer is compact in structure, high in precision, good in linearity and wide in measurement range, can be installed and used easily and conveniently and is light, shortcomings of narrow frequency band and slow response of the traditional electromagnetic transformer can be overcome, and the outdoor integral intelligent combined transformer has an important practical significance and high application value in modification and improvement on existing electrical equipment of transformer substations and construction of all-digital intelligent transformer substations.

Description

technical field [0001] The invention belongs to the technical field of electric energy metering devices, in particular to an outdoor integrated intelligent combination transformer. Background technique [0002] At present, with the rapid development of electronic technology, microcomputer relay protection and electronic ammeters gradually occupy a dominant position. In relay protection and measurement, the energy flow and information flow of the control part are separated, so the monitoring equipment no longer needs high Transformer for power output. At the same time, due to the rapid development of the power industry and the application of substation integrated automation and distribution automation, it is imminent to develop a new low-energy transformer with measurement, protection and communication capabilities. Contents of the invention [0003] The invention provides an outdoor integrated intelligent combination transformer, which aims to solve the problems of narrow...
