Abstract

The invention relates to a test system and a test method for the placement test on the mechanical life and the electric life of a high-voltage DC contactor in the field of new energy automobiles. Thetest system comprises a 24V switching power supply (1), a first power-on delay relay TIMER 1 (2),a first five-foot relay J1 (3), a second power-on delay relay TIMER 2 (4), a second five-foot relay J2(5), a third five-foot relay J3 (6), a fourth five-foot relay J4 (7), a DC24V electric pulse signal counter (9), a tested high-voltage DC contactor K (10), a piezoelectric passive buzzer (8), a 380V industrial AC-to-DC rectifier bridge power module (13), a power resistor (11), and a fast fuse (12). The test system is simple in structure, low in cost and high in practicability and specificity. By adopting the test method, the requirements of a high-voltage DC contactor user to carry out the test on the mechanical life and the electric life of different brands of products in the field of new energy automobiles can be satisfied at a very small cost.

Description

technical field [0001] The invention relates to the technical field of mechanical and electrical life testing of contactors, in particular to a system and method for thoroughly testing the mechanical life and electrical life of high-voltage DC contactors with a small sample size in the DC high-voltage field of new energy vehicles. Background technique [0002] The existing contactor mechanical life test system or electrical life test system is relatively complicated, consisting of a power supply part, a control part and an execution part. Among them, the power supply part can meet the supply of AC voltage of different voltage levels, and the DC part of the IGBT is rectified into an adjustable DC power supply, which can meet the supply of DC power supply, so it can be compatible with testing AC contactors and DC contactors; the control part includes industrial computers (including control software), PLC, protection and measurement components, etc., in order to provide system ...
