Conceptual Design for solving “Two-Step” and “Manual Not Charging” Defects of Motorized Operator accessory of MCCB

Abstract

In today’s scenario, every product may work stand-alone, however the product will be more effective if accessory is used along with.  The main reason behind this is the ease of use and the increase in automation level. There are so many products available in the market for the use of the customers, but if the customer gets the product along with the suitable accessory, it enhances product features and in turn the usability of the product. This leads to improve the customer satisfaction. The combination of product and its accessory must work simultaneously just like marriage-based combination. The increased of the cost of the product i.e. along with the accessory is compensated by its enhanced reliability and the quality of the product. In this paper, the accessory of MCCB is designed to fulfill the demands of customers by making product more qualitative and reliable.  MCCBs are basically, Short Circuit Protective Device (SCPD). MCCB protects electrical load against short circuit and overload faults, which can damage electrical appliances and may lead to unsafe conditions at the site of installation. L&T offers various range of MCCBs, with external accessory which is Motorized Operator. Motorized Operator is mounted on MCCB and make the operation remote controlled. We can operate the MCCB from the control room with the help of Motorized Operator. In this paper, the challenge is to make the Motorized Operator more reliable and enhanced quality while operating with MCCB. During the scope of the paper, various stages of product reliability enhancement such as problem definition, component measurement, detailed analysis, concept development, prototyping, validation testing, product design release, improvement and its sustainability is worked upon.
