A test method for multi-standard voltage generator sets

Abstract

The invention relates to a method for testing various types of voltage generator sets, and belongs to the technical field of power equipment. The method is implemented through a system for testing various types of voltage generator sets. The system comprises a group of load cabinets, and the front end of each load cabinet is additionally provided with a low-voltage testing unit and a high-voltage testing unit, which are connected in parallel and respectively comprise a workbench position, a measurement cabinet and a switch cabinet, wherein the workbench position, the measurement cabinet and the switch cabinet are connected sequentially. Each high-voltage testing unit is provided with a transformer between the corresponding switch cabinet and the load cabinet. Simultaneous contact cabinets are respectively connected between each two adjacent testing units. In use, a to-be-tested generator set is put at the workbench position and is connected, and the corresponding switch cabinet is communicated with the corresponding simultaneous contact cabinet, thereby achieving the independent testing or parallel testing of various types of voltage generator sets, greatly reducing the wiring and setting workload, and remarkably improving the testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a test method for multi-standard voltage generating sets. Background technique [0002] Whether the output power of the generator set meets the standard and whether the output electrical parameters are stable requires R&D experiments, type inspection, factory testing and regular maintenance. In these tests, load cabinets are required to absorb electrical energy, detect electrical parameters, and evaluate the generator set. the quality of.

Problems solved by technology

[0003] For generator set developers and manufacturers, there are many specifications and models of the units, the voltage level is from low voltage 380V to high voltage 10.5kV, the coverage is large, and the power is uncertain. One load cabinet cannot be compatible with the test of all specifications of generator sets. If The tester purchases a load cabinet with corresponding specifications for each voltage generator set, which will bring a huge cost burden to the tester. For this, the existing solution is to add a load cabinet between the generator set and the load cabinet. The transformer can make the load test cover two voltages, but for some large manufacturers, there are more than two voltage levels of the generator set, such as 380V, 440V, 690V, 3.3kV, 6.6kV, and 10.5kV. Transformers with more specifications, when the number of transformers increases, the work of wiring and setting becomes very cumbersome

Testers need to connect generator sets, transformers and load cabinets of different specifications with busbars according to each test specification, and adjust various switches on the transformer and load cabinets to combine the required power. If more Parallel testing of 1 generator set, the time for each wiring and setting even exceeds the time for electrical testing
