Product Description
Switchgear stands as the cornerstone of modern electrical systems, engineered with precision to masterfully handle the opening, closing, controlling, and safeguarding of electrical devices throughout the entire spectrum of power generation, transmission, distribution, and conversion activities. Its foremost purpose is to guarantee uninterrupted functionality and protection, ensuring a flawless operation across a wide array of power infrastructures.
Structure
Our high voltage switchgear is thoughtfully designed with a sophisticated compartmental structure, featuring distinct sections including the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is meticulously separated with durable steel partitions for enhanced safety. Taking the KYN28A-12 model as an example, the instrument room is strategically placed at the top, the circuit breaker room is centrally located, and the cable room is stationed at the base, offering a well-organized and efficient layout.
Low voltage switchgear is adeptly categorized based on component installation methods into fixed and drawer configurations. The drawer type switchgear boasts a durable fixed cabinet body, beautifully integrated with a versatile section that allows for dynamic movement, providing both stability and flexibility in its design.
Internal Components
The essential internal components encompass circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of advanced protective devices. These components are orchestrated in harmony to ensure unparalleled operational efficiency and safety, exemplifying cutting-edge technology and design.
Classification
Switchgear is distinctively classified by the circuit breaker's installation mode into movable and fixed types. Cabinet structures are further categorized as open, metal enclosed, or metal enclosed armored. Distinguished by voltage levels, they are classified as high-voltage (exceeding AC1000V) or low-voltage (below AC1000V), and by voltage waveform, they are divided into AC and DC types. Furthermore, they fulfill specific roles such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, catering to a diverse array of functional requirements.
Effect
Control Function: Expertly orchestrates circuit connectivity to proficiently conduct the start and stop operations of power equipment, delivering precise control and peak performance with reliability at its core.
Protection Function: Delivers robust protection by automatically disconnecting circuits in the face of overloads, short circuits, or leakage events, thereby safeguarding both equipment and personnel from potential hazards, and maintaining a safe operational environment.
Application Location
Perfectly suited for installation in power plants, substations, petrochemical plants, metallurgical and steel rolling facilities, light industry textiles, various manufacturing sectors, mining operations, residential complexes, and high-rise buildings, ensuring steadfast and reliable performance in a multitude of settings.
