specific Embodiment
[0024]The purpose of this application: for the test method of the existing integrated volt-ampere characteristic tester, although the test data can be directly given, the grounding wire of the secondary side of the current transformer under test installed in the switch cabinet is released and restored. For testers, the operation is very inconvenient and affects the work efficiency and test accuracy. The device provided by the application can replace the sliding resistor, which is easier to operate and reduces the cost of use.
[0025] Main technical solutions:
[0026] 1) Use an ordinary hard insulating bucket with a suitable capacity as the main carrier of the device;
[0027] 2) Fix two narrow strip-shaped insulating plates with certain strength on both sides of the bucket as support;
[0028] 3) Open two holes with a certain gap on one side of the insulation board to install the incoming and outgoing terminals;
[0029] 4) The inner side of the outlet end is connected to ...
Embodiment 1
[0036] In order to solve a series of problems in the process of integrated volt-ampere characteristics, according to the design idea, the specific implementation plan is as follows:
[0037] 1. Device production
[0038] 1) Purchase a hard insulated water bucket of suitable capacity;
[0039] 2) According to the size of the bucket, process and make insulation boards on both sides for supporting and covering the soft copper braid at the bottom of the bucket;
[0040] 3) Drill a hole at a suitable position on one side of the insulation board, and install the incoming and outgoing wiring terminals;
[0041] 4) Make beams;
[0042] 5) Assemble and connect components according to the main technical scheme;
[0043] 6) Solution ratio, tap water is used as the base liquid to process industrial salt to form a conductive solution. Usually the ratio of water to salt is 100:1, which can be adjusted appropriately for different regions and water quality. Just go to 5A.
