Abstract

In order to make the breaking and closing operation of MCCB handle reach the optimal use state, this paper takes the MCCB with 4P pole number as the research object, focuses on the MCCB handle modeling, studies all problems in the MCCB handle operation with ergonomic methods, discusses the basic principles of ergonomics in depth, and integrates the national MCCB standard to study the contact relationship between the operation finger end and the handle during the force application process to analyze handle shape, size, edge chamfe, anti-slip area and panel depth design. Through measurement, test and systematic analysis, accurate research conclusions were drawn, improvement methods and suggestions. A series of improvements aim to enhanced the operability of the MCCB handle and improved the operating experience of the operator, which provides certain reference value for the research on improved handle modeling design of similar products.
