Abstract

The invention relates to an on-site standard current transformer integrated device, for resolving the problems of the prior art such as disorder wiring, low safety, difficult motion, narrow detection range and low efficiency, which comprises a multi-ratio main current transformer (1) and a single-ratio auxiliary current transformer (2) for converting the secondary coil 5A of the current transformer into 1A cascade which are arranged at the left of a frame in a shell (7), and a current booster (6) at the right of the frame in the shell (7), wherein the hole of the annular iron core of the multi-ratio main current transformer (1) is opposite to the hole of the annular iron core of the current booster (6), the horizontal distance between the multi-ratio main current transformer (1) and the current booster (6) is 100 to 200mm, a front panel (4) is arranged between the multi-ratio main current transformer (1) and the current booster (6) and is provided with a through hole. The on-site standard current transformer integrated device has high integrality and fast on-site detection.

Description

technical field [0001] The present invention relates to a standard current transformer integrated device for on-site electric energy measurement and detection of power transformers at the gate, in particular to a self-rising current standard current transformer in which the standard current transformer and the current booster adopt a three-way core hole structure integration and its integrated devices. Background technique [0002] At present, there are three kinds of standard current transformers for electric energy measurement and detection, one is the standard current transformer with no core-piercing and current booster, and the other is the more common standard current transformer with its own current booster and one-way core-through type. There is also a standard current transformer without a current booster that needs to be equipped with a current booster. These three standard current transformers and current booster equipment are benzene-heavy, and the panels are co...
