Product Description
Switchgear is an indispensable pillar in the realm of electrical systems, engineered to masterfully oversee the opening, closing, controlling, and safeguarding of electrical apparatus throughout the intricate processes of power generation, transmission, distribution, and conversion. Its core purpose is to guarantee smooth, uninterrupted operation and robust protection across a vast array of power systems.
Structure
High voltage switchgear boasts a meticulously organized structure, featuring clearly defined compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. These compartments are thoughtfully insulated with durable steel partitions. Specifically, in the KYN28A-12 model, the instrument room proudly resides at the top, the circuit breaker room takes center stage, and the cable room is situated at the base.
Low voltage switchgear is expertly categorized according to the installation method of its components into fixed and drawer types. The drawer type switchgear is distinguished by a robust fixed cabinet body that seamlessly integrates with a flexible, movable device section, offering enhanced functionality and adaptability.
Internal Components
The switchgear's internal components are pivotal to its performance, featuring essential elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of sophisticated protective devices, all meticulously harmonized to ensure operational excellence and uncompromised safety.
Classification
Switchgear can be astutely classified by the circuit breaker's installation method into movable and fixed types. Cabinet structures vary, ranging from open, to metal enclosed, to metal enclosed armored configurations. Voltage levels further distinguish them into high-voltage (exceeding AC1000V) or low-voltage (less than AC1000V) categories, while voltage waveform differentiates them into AC and DC. Moreover, they fulfill specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, tailored to meet diverse electrical requirements.
Effect
Control Function: With unmatched precision, it manages circuit connectivity to enable seamless start and stop operations of power equipment, ensuring precise control and peak performance.
Protection Function: Delivers unparalleled protection by automatically disconnecting the circuit during overloads, short circuits, or leakage incidents, thereby safeguarding both equipment and personnel from potential hazards.
Application Location
Perfectly suited for deployment in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings, it ensures dependable performance across an array of challenging environments.
