Abstract

The invention discloses a test device and a test method capable of simulating insulation resistors and absorption procedures of different appliances. The test device comprises a shell. An insulation resistor simulation branch circuit and an absorption procedure simulation branch circuit which are connected with each other in parallel are arranged in the shell; the insulation resistor simulation branch circuit comprises a plurality of parallel connection branch circuits, each branch circuit is provided with built-in resistors and relays which are serially connected with one another, and resistance values of the built-in resistors of the various branch circuits are different from one another; the absorption procedure simulation branch circuit comprises variable resistors and variable capacitors which are serially connected with one another, and spark gaps are reserved on two sides of each capacitor, so that protection can be carried out; wiring clamps are arranged at two ends of the insulation resistor simulation branch circuit and two ends of the absorption procedure simulation branch circuit, so that the insulation resistor simulation branch circuit and the absorption procedure simulation branch circuit can be connected with tested devices. The test device and the test method have the advantages that the test device and the test method can be used with primary appliances such as current transformers and voltage transformers, the different branch circuits in a test chamber can be closed or opened, and accordingly the insulation resistors under different conditions can be simulated; different test data can be obtained and can be analyzed by operation personnel.

Description

technical field [0001] The invention relates to a test device and method capable of simulating the insulation resistance and absorption process of different equipment. Background technique [0002] For the electrical equipment (current transformer, voltage transformer, etc.) in the training room, because it is out of operation, and the ambient temperature, humidity and other parameters are relatively stable, its insulation resistance value is relatively stable. For beginners, the single data is not conducive to understanding the meaning of insulation resistance and judging the status of equipment. [0003] Therefore, there is an urgent need for a test device that can simulate the insulation resistance and absorption process of different equipment. Currently, there is no such test facility. Contents of the invention [0004] In order to solve the above problems, the present invention proposes a test device and method that can simulate the insulation resistance and absorpt...
