Abstract

The invention discloses a power transformer test bench, which comprises a main control computer, a control conversion board, a test signal source, a test load and a switching device, the control conversion board is connected to the control signal output end of the main control computer, and the switching device is controlled by switching The board is respectively connected to the test signal source, the test load and the test instrument; the data output terminal of the test instrument is connected to the main control computer, and the control terminal of the test signal source is connected to the main control computer; the transfer device is connected to the transformer under test. The power transformer test bench of the present invention has high test efficiency, can realize multiple functions of one machine, and satisfies the needs of on-site testing.

Description

[0001] [technical field] [0002] The invention relates to power transformer testing, in particular to a power transformer testing platform. [0003] [Background technique] [0004] In the railway signal equipment, the series production and inspection of power transformers lack a comprehensive test platform, basically use manual testing, and lack the necessary testing equipment. The connection method for manual testing is as follows figure 1 As shown, it includes test signal source, test load and test instrument; the test signal source and test load provide test conditions for the transformer under test, and the test data is read out through the test instrument to judge the test result. Because human testing is prone to errors and mistakes. Bring product instability. In addition, due to the power transformer series products, there are many types. It brings a heavy workload to build a test environment. The function of the existing test bench is very single, and the test pro...
