Embodiment Construction

[0026] An overcurrent component testing device provided in an embodiment of the present invention, such as figure 1 As shown, including: water source system 11, deionization system 12, water circulation system 13 and test platform 15, wherein,

[0027] The test platform 15 is used to set the overcurrent component to be tested, and a water circulation pipeline for testing is arranged on the outside of the overcurrent component to be tested. The overcurrent component to be tested can be a water cooling plate radiator in the water cooling system of the converter valve module , saturated reactor and water resistance;

[0028] The water circulation system 13 is connected to the water circulation pipeline to provide circulation power for the cooling water in the water circulation pipeline. The water circulation system and the test platform 15 are flexibly connected through a hose, which is convenient for adjusting the test platform 15;

[0029] Among them, the water circulation sys...

Abstract

An over-current assembly test device provided by the invention comprises a test platform configured to arrange an over-current assembly to be tested, wherein a water circulation pipeline for test is arranged at the outer side of the over-current assembly to be tested; a water circulation system connected with the water circulation pipeline and configured to provide cycle power for the cooling in the water circulation pipeline; a water source system configured to provide cooling water for the water circulation pipeline; and a deionization system connected with the water source system and the water circulation system to send the cooling water after deionization into the water circulation system. The problems are solved that the cooling water for water cooling test is not subjected to deionization operation, the conductivity in the cooling water is high to easily disturb the test result so as to cause inaccurate test result.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a testing device for an overcurrent component. Background technique [0002] Nowadays, with the development of power transmission to a higher voltage level, the power electronic components in the core equipment converter valve module have the advantages of small structural size, light weight, fast response speed, high energy conversion efficiency, and convenient control. It is more and more widely used in electric energy replacement circuits, the power density is getting higher and higher, and the heat generated is also increasing. The traditional air-cooled cooling method can no longer meet the heat dissipation requirements. In order to solve the problem of high-power cooling, the cooling method has also changed from Air cooling is developing towards water cooling. At present, water cooling has become the most mature cooling method for high-power power electronic devices. However...
