The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
(1) Verification problem of 200 mechanical running-in tests
At present, all factory tests of the combined electrical apparatus are verified through type tests (the type tests are tests performed to verify whether products can meet all requirements of technical specifications), and 200 mechanical running-in tests do not pass relevant verification.
(2) Applicability of 200 mechanical break-in test tests
Based on the silver plating process, the silver plating thickness, the difference in the conductor base material and the difference in the contact holding force in each manufacturing plant, the running-in times required to achieve the ideal degree of fit are necessarily inconsistent. In other words, some manufacturers may not achieve the desired effect after 200 running-ins, and some manufacturers may not need to achieve the desired effect after 200 running-ins. Therefore, the number of running-ins needs to be verified by relevant type tests according to the actual conditions of each manufacturing plant.
(3) Cleaning after running-in

At present, each manufacturing factory is to perform running-in after an arc extinguish chamber (a core unit of a combined electrical apparatus) is assembled, metal powder generated in the running-in process can be cut to form displacement to each position due to factors such as vibration of mechanical operation, air flow in an air chamber and the like in the running-in process, the surface of the arc extinguish chamber can be easily cleaned, but dead angles which are not easy to clean exist, and huge potential safety hazards are left. Although the foreign matter hidden in the dead angle is not generated through test means such as lightning impulse, power frequency voltage resistance, partial discharge measurement and the like in a manufacturing plant, the product can be considered to be qualified and delivered from a factory, the hidden foreign matter can be displaced to a high potential area by various objective factors such as bumping of long-distance transportation, operation of field installation and acceptance, electric power generated by large current after power transmission and the like, and thus huge hidden dangers are buried for safe operation of equipment.
