The invention relates to testing of protective adapter boards, in particular to a testing device for the protective adapter boards. The technical problems that at present, when the IGBT protective adapter boards are tested, testing efficiency is low, and the testing qualified rate is low are solved. The testing device for the protective adapter boards comprises a device supporting frame made of a transparent insulating material, the device supporting frame is composed of a front vertical panel, a rear vertical panel and an upper panel horizontally connected between the two top ends of the vertical panels, the middle of the upper panel in the length direction serves as the installation area of the protective adapter boards, a plurality of insulating supporting columns matched with the protective adapter boards and two pairs of spring installing clamps are installed along the center line of the area, and each pair of spring clamps is distributed on the two sides of the installation area of the protective adapter boards. By the adoption of the testing device for the protective adapter boards, production efficiency is greatly improved, labor cost is reduced, and the design cost of power units is reduced to a certain degree, so that the testing device has higher market competitiveness.
Description
technical field [0001] The invention relates to the field of testing protection adapter boards, in particular to a testing device for protection adapter boards. Background technique [0002] With the rapid development of China's economy, it has brought unprecedented opportunities for the development of China's railways. According to the development plan of China's railway passenger dedicated lines, by 2010 it is necessary to complete the four vertical and four horizontal passenger dedicated lines and the Bohai Rim, Yangtze River Delta, and Pearl River Delta regions. The construction of intercity rail transit system and the rapid development of heavy-duty high-speed freight railways require a large number of high-speed EMUs and heavy-duty electric locomotives. The operation of EMUs and locomotives is inseparable from traction, so a large number of The traction converter, as the core component of the traction converter, that is, the power unit, needs to be manufactured in larg...
