[0010] Fig. 1 It is the structural schematic diagram of the utility model;
[0011] Fig. 2 It is the circuit schematic diagram of the utility model. DETAILED DESCRIPTION
[0012] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0013] Referring to Figs. 1-2 The specific embodiment adopts the following technical scheme: a novel MSD high-voltage interlocking automatic test tool, comprising an MSD handle 1, a relay 2 and a banana head 3, the MSD handle 1 is connected with the banana head 3 through the relay 2, and the banana head 3 is connected with a DC 24V power supply 4 of an EOL test machine.
[0014] The MSD handle of the specific embodiment is RC-MSD1-630A / 750V-H-D, and the relay is OMRON MY2N-D2-GS24VDC. The U-shaped interlocking PIN needle of the MSD handle is cut off and connected to the normally closed end of the relay, and the power supply end of the relay is inserted into the DC 24V power supply of the EOL test machine through the connecting banana head. Under normal circumstances, the relay coil is not powered, and the high-voltage interlock is in a closed state. When it is necessary to detect the disconnection state of the high-voltage interlock, the DC 24V power supply of the EOL test machine powers the relay coil to realize the disconnection of the high-voltage interlock. The action of manually pulling out the MSD is simulated by the relay closure, which eliminates the manual plugging action, saves the test time and improves the test efficiency.
[0015] The specific embodiment automatically controls the on-off of the high-voltage interlock through the relay, eliminates the need for manually plugging in and pulling out the MSD handle, realizes automatic testing, and greatly improves the test efficiency. Since the MSD handle does not need to be manually plugged in and pulled out, the testing process is more rapid, and the time required for manual operation is reduced. The automatic test tool can reduce the risks brought by manual operation, especially in the case of high-voltage electricity, which improves the safety of the testing process. The automatic testing process can ensure the consistency of each test condition, reduce human errors and improve the reliability of the test results. The use of relays and banana heads simplifies the test operation steps and makes the testing process more simple and easy to operate. The MSD handle and the relay used are common models on the market, which are easy to purchase and replace, and have good compatibility and universality. By improving the test efficiency and reducing manual operation, the overall test cost can be reduced and the production efficiency can be improved.
