Product Description
Switchgear plays an indispensable role in the realm of electrical systems. Engineered for excellence, it efficiently manages the opening, closing, controlling, and protection of electrical devices during power generation, transmission, distribution, and conversion. Its foremost duty is to guarantee seamless operation and safeguarding across various power systems, ensuring reliability and peace of mind.
Structure
High voltage switchgear is designed with precision, featuring separate compartments like the busbar room, circuit breaker room, secondary control room (commonly referred to as the instrument room), and feeder room. Each unit is securely isolated with steel partitions. In the KYN28A-12 model, the instrument room is strategically placed at the top, the circuit breaker room occupies the central position, and the cable room is situated at the bottom, highlighting a well-thought-out structural design.
Low voltage switchgear is expertly categorized based on the installation technique of its components into fixed and drawer types. The drawer type switchgear is characterized by its sturdy fixed cabinet body, enhanced by a flexible movable device section, offering both durability and versatility.
Internal Components
The key internal components are a testament to technological advancement, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of sophisticated protective devices. These elements work in harmony to ensure operational efficiency and uncompromised safety.
Classification
Switchgear boasts a diverse classification system based on the circuit breaker's installation method into movable and fixed types. Its cabinet structures are further divided into open, metal enclosed, or metal enclosed armored categories. Voltage levels classify them as high-voltage (above AC1000V) or low-voltage (below AC1000V), while voltage waveform further divides them into AC and DC variations. They serve specialized roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and beyond, catering to a wide array of applications.
Effect
Control Function: Meticulously manages circuit connectivity to facilitate seamless start and stop operations of power equipment, ensuring precise control and peak performance. This function optimizes equipment functionality, providing unmatched control.
Protection Function: Offers fortified protection by automatically disengaging the circuit during overloads, short circuits, or leakage incidents, thereby safeguarding both equipment and personnel from potential hazards. This function is crucial in maintaining the integrity and safety of the system.
Application Location
This switchgear is ideally suited for deployment across power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings. It guarantees reliable performance, ensuring robust operational support in a multitude of environments.
