Application analysis of the automatic bypass of primary fan frequency converter

Abstract

Abstract:

A frequency converter of a company is equipped with automatic bypass conditions, but without switch scheme. Therefore, the automatic switch to the bypass cannot be realized when there is fault in frequency converter，which brings hidden trouble to the safety of the units. Taking an automatic bypass of the primary fan in 2×350MW units as an example, it analyzes the feasibility. The analysis provides automatic bypass scheme for the frequency converter of the company. 
