Detecting device and detecting system for electronic transformer

Abstract

The invention provides a detecting device and detecting system for an electronic transformer. A control signal for detecting an electronic transformer is output through a control unit. A voltage errorof the electronic transformer is determined based on a reference voltage and a target voltage that are received. A current error of the electronic transformer is determined based on a reference current and a target current that are received. First test power utilization and second test power utilization are output according to the detection control signal by using a controlled voltage source. A test voltage and the reference voltage are output by a standard voltage mutual induction unit with boosting according to the first test power utilization. The test voltage is used for enabling the electronic transformer to output the target voltage. A test current and the reference current are output by a standard current mutual induction unit with the up-flow according to the test utilization. Thetest current is used for enabling the electronic transformer to output the target current. In this way, no manual debugging is required during the test of the electronic transformer, and the test efficiency of the electronic transformer is improved.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a detection device and a detection system of an electronic transformer. Background technique [0002] Both electronic voltage transformers and electronic current transformers are called electronic transformers. As electronic transformers are widely used in power transmission systems such as ring network cabinets and pole-mounted switches, the demand for electronic transformers is also increasing. bigger. [0003] Although the existing electronic transformer calibrator can perform performance tests on the electronic transformer before leaving the factory, but in the process of using the calibrator to test the electronic transformer, it is necessary to rely on manual debugging and operation of the calibrator To be able to complete the test, the test efficiency is low. Contents of the invention [0004] Embodiments of the present invention provide a detection dev...
