Embodiment Construction

[0030] see figure 1 Shown, be the block diagram of tool main high voltage multi-point test equipment and method provided by the present invention, mainly comprise:

[0031] A high / low voltage switching device 1, the high / low voltage switching device 1 includes an array of high voltage switches SH and several low voltage switches SL, so that the voltage output mode of the high / low voltage switching device 1 is that of each group of high voltage switches SH and low voltage switches SL switch on and off;

[0032] A test channel group 2, the test channel group 2 includes multiple groups of test channels 21a-21n, each group of test channels 21a-21n is connected to a group of high-voltage switches SH and a low-voltage switch SL of the high / low voltage switching device 1, When the high-voltage switch SH is in the conduction state (ON), the low-voltage switch SL is in the non-conduction state (OFF), so that the single test channels 21a-21n can only selectively output high-voltage or ...

Abstract

The invention relates to high-voltage multi-point testing equipment and a method with main and auxiliary steps. The method comprises the following steps of: connecting a plurality of groups of objects to be tested with the testing equipment and setting various testing parameters through an input device; when testing is begun, carrying out a main-step high-voltage testing program firstly, i.e. simultaneously outputting high voltage to the plurality of groups of objects to be tested through a high voltage generating device, and detecting whether the plurality of groups of objects to be tested are normal or not in the main-step testing program through a central control unit; if so, judging the plurality of objects to be tested are all good products to finish testing; and if the central control unit judges any one of the plurality of objects to be tested is abnormal, entering an auxiliary-step testing program, i.e. respectively testing each group of objects to be tested, and displaying testing results on a display, therefore, which group of tested objects are defective products can be learnt by virtue of the display results on the display. The invention can reduce the testing time andimprove the testing speed and is easy to reject the defective products by operators.

Description

technical field [0001] The present invention relates to a testing device, in particular to a high-voltage multi-point testing device and method with primary and secondary steps for parallel testing of multiple objects to be tested in a group mode. Background technique [0002] For general component testing, such as motors, fans, or transformers, the quality inspection must use a withstand voltage machine for high-voltage measurement to confirm whether the object under test meets the withstand voltage conditions of safety specifications. [0003] Therefore, in order to ensure that each component is a good product, a high-voltage test procedure must be carried out before each component leaves the factory. Taking a transformer as an example, the transformer must at least test the primary to core, core to secondary, and primary to secondary Waiting for three test procedures, if each test must be performed for 1 second, each transformer must spend 3 seconds in the test before the...
