Current transformer detection operation table and multi-position top-speed current transformer calibration system

Abstract

The invention provides a current transformer detection operation table. The current transformer detection operation table comprises a movable workbench, and a current booster, a standard current transformer, a program control transformer calibrator, a program control current load box, a linear program control electronic power supply, a first communication system and a second communication system which are arranged in the movable workbench. The standard current transformer is provided with h primary windings and n secondary windings, the movable workbench is provided with a connecting structureused for enabling m tested current transformers to be connected with the standard current transformer at the same time, and h, m and n are positive integers respectively. The invention further provides a multi-position top-speed current transformer verification system. The multi-position top-speed current transformer verification system comprises a two-dimensional code generation device, a scanning gun, a PC, a printer and the current transformer detection operation table. According to the invention, full-automatic error verification of a plurality of mutual inductors is completed at the sametime under one-time wiring of only one set of device, so that the working efficiency of the test is greatly improved, and the test precision is also improved at the same time.

Description

technical field [0001] The invention relates to the technical field of transformer performance testing, in particular to a current transformer testing console and a multi-position extremely fast current transformer calibration system including the same. Background technique [0002] The current transformer plays the role of current transformation according to the ratio, and is used to provide current signals with an accurate proportional relationship with the primary circuit for electrical measurement, electric energy metering, and automation devices. At the same time, it is also used to provide signals for instruments and relay protection, so the reliability, stability and accuracy of transformers play a vital role in the safe operation and marketing measurement of power systems. The national verification regulation JJG313-2010 "Measurement Current Transformer" clearly stipulates that each metering transformer needs to pass the first inspection and periodic inspection befor...
