Multi-channel electronic transformer intelligent calibrator

Abstract

The present invention discloses a multi-channel electronic transformer intelligent calibrator which comprises a body, multiple electronic transformer interfaces which are arranged on the body and are used for connecting multiple electronic transformers, multiple standard signal interfaces which are arranged on the body and are used for connecting a standard transformer, a sub control module which is arranged in the body and comprises an electronic transformer acquisition module and a standard signal acquisition module, a master control module which is arranged in the body and controls the sub control module and calibrates the multiple electronic transformers according to the data information of multiple electronic transformers and the data information of the standard sensor collected by the sub control module. The multi-channel electronic transformer intelligent calibrator can be connected to multiple electronic transformers at the same time, the electronic transformers and the multi-channel electronic transformer intelligent calibrator are directly connected through the multiple electronic transformer interfaces, the testing of the electronic transformer performance is realized without a connection and combination unit, and the testing efficiency is improved.

Description

Technical field [0001] The invention relates to an electronic transformer calibrator, in particular to a multi-channel electronic transformer intelligent calibrator. Background technique [0002] The electronic transformer calibrator is an electronic transformer verification device used to verify the key performance indicators of electronic transformers. The current electronic transformer calibrator related patents (CN 202916434 U, CN 101290345B, CN101413995B, CN 101872004B, CN 102012494B) mentioned in the current transformer calibrator exist cannot connect more than two electronic transformers at the same time, and must be combined The problem that the unit is connected to the electronic transformer and cannot be connected to more than two combined units is not conducive to mass production testing; and the electronic transformer calibrator of the prior art does not have the temperature control function of the thermostat, and cannot perform the thermostat Automatic control, manu...

Problems solved by technology

At present, the transformer calibrator mentioned in the relevant patents of electronic transformer calibrator (CN 202916434 U, CN 101290345B, CN101413995B, CN 101872004B, CN 102012494B) cannot connect more than two electronic transformers at the same time, and must be merged The unit is connected to the electronic transformer and cannot connect more than two combined units, which is not conducive to mass production testing; and the electronic transformer calibrator of the prior art does not have the temperature control function of the thermostat, and cannot perform thermostat Automatic control, manual setting is inefficient, and it is inconvenient to obtain the actual temperature curve of the incubator during the test; there is no automatic control interface for current booster / booster, and the current cannot be automatically adjusted. When adjusting small signals (less than 10A), manual The control cannot be adjusted accurately at one time, and repeated attempts are required; there is no digital interface for high-precision signal sources, and it is impossible to use external high-precision signal sources to directly calibrate the calibrator
