Abstract

The invention discloses a current converting and detecting device and a current detecting method. The device comprises a current transformer which comprises a primary side and a secondary side and is used for converting primary current connected to the primary side into secondary current of the secondary side, at least one selection terminal which is connected to the primary side, and a selection circuit which is connected to the primary side of the current transformer and the at least one selection terminal and is used for selecting the primary side of the current transformer to be in conduction with one of the at least one selection terminal. According to the device and the method, a technical problem that power cut and wire change are needed in testing electrical parameters of primary equipment in the related technology is solved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a current conversion and detection device and a current detection method. Background technique [0002] In the acceptance and verification work of user substations and residential power distribution rooms, it is necessary to convert the primary current of the primary equipment into secondary current, and connect the primary equipment with the current transformer. Due to the narrow distance between the equipment, the wiring is inconvenient. Waste of time, resulting in low work efficiency, it is very necessary to have a feasible solution to connect the primary equipment and test auxiliary equipment conveniently and quickly under the premise of carrying out the current transformer test in accordance with the work flow, shorten the wiring time of the relay protection test, and improve the work efficiency. Efficiency, reducing the required power outage time and improving grid reliability. [0...
