Abstract

The invention discloses a transformer verification system and a verification method. The verification system comprises a control cabinet, a self-boosting standard voltage transformer, a current transformer detection table, a two-dimensional code generation device, a code scanning gun and a PC. The control cabinet comprises a program-controlled voltage load box, a program-controlled current load box, a program-controlled transformer calibrator, a linear program-controlled electronic power supply and a control cabinet communication system. A current booster, a standard current transformer and acurrent transformer detection communication system are arranged in the current transformer detection table. A plurality of current transformers can be connected to the current transformer detection table. Error verification of the voltage transformers and the current transformers can be realized, full-automatic simultaneous error verification of multiple current transformers can be completed at the same time under the condition of one-time wiring of only one set of device, the verification efficiency is greatly improved, and manual wiring is less and simple.

Description

technical field

[0001] The invention relates to the technical field of transformer performance testing, in particular to a transformer calibration system and calibration method. Background technique

[0002] The transformer plays the role of high-voltage isolation and voltage and current transformation according to the ratio, and is used to provide voltage and 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 and high-voltage isolation for instruments and relay protection, so the reliability, stability, and accuracy of the transformer play a vital role in the safe operation of the power system and marketing measurement. The national verification regulations JJG313-2010 "Current Transformer for Measurement" and JJG314-2010 "Voltage Transformer for Measurement" clearly stipulate that each transformer for measuremen...
