Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment testing technology, specifically relating to an auxiliary device for contactor life testing. Background Technology

[0002] According to Clause 9.2.9 of standard GB / T 21413.2-2021 "Electrical Equipment for Rail Transit Locomotives and Rolling Stock - Part 2: General Rules for Electrical Components", each operating cycle includes a closing operation followed by a closing operation (without current), or (if applicable) a connecting operation followed by a disconnecting operation (with current). Each operating sequence includes 2,000,000 cycles of operation without current, and the opening and closing times are not explicitly required. However, there is currently no corresponding testing equipment on the market. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary device for contactor life testing to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a contactor life test auxiliary device, including a bracket, characterized in that: the bracket is welded with angle steel, a table is provided on the top of the bracket, the table is made of epoxy board, a PLC module is provided on the left side of the table, an intermediate relay is provided in the middle of the table, an intelligent touch screen is provided on the right side of the table, and a contactor is fixed on the right side of the bracket.

[0005] The beneficial effects of this utility model are: Compared with the prior art, this utility model uses a relatively simple structure to realize the life detection of the contactor. The number of detections can be designed as needed, with a maximum of ten million times, and the control time can be accurate to 1 second. Attached Figure Description

[0006] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings: Figure 1 This is an overall structural diagram of the present invention; Figure 2 This is the control circuit diagram of this utility model. Detailed Implementation

[0007] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0008] A contactor life testing auxiliary device includes a support frame 1, characterized in that: the support frame 1 is welded from angle steel, a platform 6 is provided on the top of the support frame 1, the platform 6 is made of epoxy board, a PLC module 5 is provided on the left side of the platform 6, an intermediate relay 4 is provided in the middle of the platform 6, and an intelligent touch screen 3 is provided on the right side of the platform 6. A contactor 2 is fixed on the right side of the support frame 1. The laboratory strictly controls the construction details of the contactor life testing platform in accordance with standards and client requirements. In terms of the number of tests, the platform can be set to more than 10 million tests, with control time accurate to 1 second and arbitrarily settable control time. Considering the simultaneous testing of multiple samples, the PLC electrical life platform can simultaneously meet 20-channel test requirements, solving the test cycle problem.

[0009] The contactor life test platform combines traditional PLC control with a modern touchscreen control system, creating a new generation of technologically advanced and convenient laboratory equipment. This platform, integrated with a PC terminal, allows for program editing and modification to implement the required test procedures. It overcomes the long-standing challenge of requiring both PLC and electrical control expertise in traditional PLC-controlled testing, significantly reducing testing difficulty and improving testing efficiency and sample preparation time.

[0010] The test platform consists of an intelligent touchscreen 3, a PLC module 5, an intermediate relay 4, a 24V DC power supply, and a 110V DC power supply. The intelligent touchscreen 3 controls the PLC module 5 to perform precision control of the sample program, while the intermediate relay 4 controls the opening and closing of the contactor 2 power supply, thus achieving control for the non-energized performance test.

[0011] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0012] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
