Abstract

The invention discloses a program-controlled current transformer automatic detecting system. The system includes a program-controlled current transformer automatic wiring device, a mutual inductor detecting and control unit, a program-controlled mutual inductor calibration table, a mutual inductor calibrator, a current load box, and a program-controlled power supply, wherein the mutual inductor detecting and control unit is connected with the program-controlled current transformer automatic wiring device, the mutual inductor calibrator, the current load box, and a program-controlled power supply, and the mutual inductor calibrator, the current load box, and the program-controlled power supply are arranged on the program-controlled mutual inductor calibration table. The system solves the technical problems of the low efficiency and accuracy of the current transformer detecting in the prior art, is reasonable in design, and can efficiently and accurately complete the program-controlled current transformer detecting.

Description

technical field [0001] The invention relates to the field of electric equipment detection, in particular to a program-controlled current transformer automatic verification system. Background technique [0002] According to the JJG313-2010 "Current Transformer for Measuring" verification regulations: the 0.05-0.01 class current transformer used as a standard device must be verified every two years, and every change must be verified during the verification. The current transformer used as a standard device generally has a transformation ratio range of 5-2000 / 5, 1A, and an accuracy level of 0.05-0.01. The transformation ratio range is wide and the grade requirements are different. In the actual verification, there will be wrong wiring. , the work efficiency is low; moreover, in the verification process of different transformation ratios of the same standard instrument, because the operator of each connection is not necessarily the same, the connection contact of different trans...
