Features: This book is divided into ten chapters, primarily elaborating on the basic structures, fault diagnosis techniques, fault causes, and handling methods of high and low-voltage switchgear and their operating mechanisms, including SF6 circuit breakers, SF6 fully enclosed switchgear, vacuum circuit breakers, oil circuit breakers, automatic reclosers and sectionizers, disconnectors and load break switches, high-voltage switchgear, automatic air circuit breakers, AC contactors, magnetic starters, and low-voltage distribution cabinets. It also provides a brief introduction to condition monitoring and condition-based maintenance. The book cites numerous examples, integrating theory with practice, and is characterized by rich content, systematic organization, and strong practicality. It is suitable for engineering technicians engaged in the operation, maintenance, installation, testing, and management of high and low-voltage switchgear in power systems. It can also serve as a reference for manufacturing departments, power users, and faculty and students of relevant disciplines in universities and colleges.
Chapter 1 Introduction
1. Characteristics of High and Low-Voltage Switchgear
High and low-voltage switchgear are important control and protection devices in power generation, transmission, transformation, and distribution systems. Their main characteristics are as follows.
1.1 Variety and Model
Currently, the high and low-voltage switchgear operating in the aforementioned systems include oil circuit breakers, low-oil circuit breakers, air-blast circuit breakers, vacuum circuit breakers, SF6 circuit breakers, SF6 switchgear, reclosers, sectionizers, automatic air circuit breakers, disconnectors, and load break switches, among others. Each type has multiple models, such as low-oil circuit breakers with models SW3, SW4, SW6, SW7, etc., and vacuum circuit breakers with over 70 models like ZN1, ZN2, ZN3, etc.
