Description
技术领域technical field
本实用新型涉及一种适用于多类型行程开关电气参数获取的试验台，可以根据实际状况对不同类型行程开关的使用情况进行模拟获取行程开关在多次操作下内部触点动态电阻、响应时间等电气参数的变化情况，实现对行程开关可靠性研究理论数据的获取。The utility model relates to a test bench suitable for obtaining electrical parameters of multi-type travel switches, which can simulate the use of different types of travel switches according to actual conditions to obtain the internal contact dynamic resistance and response time of the travel switch under multiple operations.

背景技术Background technique
行程开关作为工业控制领域实现终端控制、限位保护的重要元器件，广泛应用于矿山、起重机械和各类机床中。近年来随着现代工业化的迅速发展，其产品需求也不断上升。同时，根据行业所需的不同，催生出了各式各样的行程开关。行程开关在实际使用过程中，由于生产或维护不当，存在质量精度差、使用寿命短、响应速度慢等问题，需要不定时的检维修，给生产带来了诸多不便，同时也为生产事故的发生埋下了隐患。每年由于行程开关失效导致安全生产事故频频发生。As an important component to realize terminal control and limit protection in the field of industrial control, limit switch is widely used in mines, hoisting machinery and various machine tools. With the rapid development of modern industrialization in recent years, the demand for its products is also rising. At the same time, according to the different needs of the industry, various travel switches have been produced. In the actual use of the limit switch, due to improper production or maintenance, there are problems such as poor quality accuracy, short service life, and slow response speed. It requires irregular inspection and maintenance, which brings a lot of inconvenience to production. Hidden dangers have been laid. Safety production accidents occur frequently every year due to the failure of travel switches.
目前对行程开关可靠性和寿命的研究，大多是基于长期故障记录统计和对可靠性分析模型进行检验，而这种失效判定形式存在较多弊端：At present, the research on the reliability and life of travel switches is mostly based on the statistics of long-term fault records and the inspection of reliability analysis models, but this form of failure judgment has many disadvantages:
（1）针对性单一，往往一种判定形式无法适用现阶段多工况、多类型行程开关的可靠性研究；(1) Single-targeted, often one form of judgment cannot be applied to the reliability research of multi-working conditions and multi-type travel switches at this stage;
（2）未得到实际模型的检验，工况条件的复杂性使得理论和实际可靠性和寿命有一定差距；(2) It has not been tested by the actual model, and the complexity of the working conditions makes the theoretical and actual reliability and service life have a certain gap;
（3）应用性差，难以对不同类型行程开关在不同时刻下的可靠性进行测定和比较，无法确定更换、检维修周期。(3) The applicability is poor, it is difficult to measure and compare the reliability of different types of travel switches at different times, and it is impossible to determine the replacement, inspection and maintenance cycle.
因此，能够针对实际情况对不同类型行程开关的可靠性进行试验研究，获取内部触点动态电阻、响应时间等参数，对其可靠性进行动态评估，得出其寿命分布状态，从而得出不同类型行程开关的检维修周期，对工业安全生产和降低事故发生率具有重要的现实意义。Therefore, it is possible to carry out experimental research on the reliability of different types of limit switches according to the actual situation, obtain parameters such as internal contact dynamic resistance and response time, dynamically evaluate their reliability, and obtain their life distribution status, so as to obtain different types of travel switches. The inspection and maintenance cycle of the limit switch has important practical significance for industrial safety production and reducing the accident rate.
