Test control device for current transformer

Abstract

The invention provides a test control device for a current transformer. The test control device is characterized in that: an output end of a power supply unit is connected with a voltage regulation unit and a power supply input end of a function control unit; the output end of the voltage regulation unit is connected with the input end of a voltage transformation unit and the output end of the voltage transformation unit is connected with a volt-ampere property test unit and the power supply input end of a power-frequency voltage withstand test unit; the power supply input end of an insulation resistor test unit is used for connecting a megameter; a volt-ampere property test control end, a power-frequency voltage withstand test control end and an insulation resistor test control end of the function control unit are respectively connected with control signal input ends of the volt-ampere property test unit, the power-frequency voltage withstand test unit and the insulation resistor test unit; a current transformer connection plug-in comprises a multi-connection-terminal connection plate which is used for connecting each joint of the current transformer to be detected and a plug; the connection plate is correspondingly connected with the corresponding terminal of the plug, and the plug is used for being plugged in the volt-ampere property test unit or the power-frequency voltage withstand test unit or the insulation resistor test unit. With the adoption of the test control device, the test efficiency of the current transformer is improved.

Description

Technical field: [0001] The invention relates to a current transformer test control device. Background technique: [0002] GIS (gas-insulated metal-enclosed switchgear) manufacturers use a large number of feed-through current transformers for GIS products. During the entire manufacturing process of GIS, these current transformers have to go through a series of tests, sub-assembly, testing, final assembly, The process of testing. In this process, in addition to meeting the general technical requirements of current transformers, it is more important to detect whether the performance of the current transformers has changed or even deteriorated during the entire assembly process of the GIS, and to confirm Whether the three-phase parameter symmetry of these current transformers meets the requirements, etc. However, in the current transformer factory, many of these tests cannot be carried out. Although the GIS factory has the test conditions, the test tools often use discrete to...

Problems solved by technology

However, in the current transformer manufacturing plant, many of these tests cannot be carried out. Although the GIS manufacturing plant has the test conditions, the test tools often use discrete tools similar to the current transformer manufacturing plant, and the testing cycle is long and cumbersome.
