Product Description
Switchgear stands as an indispensable pillar in the realm of electrical systems. It is ingeniously crafted to manage with finesse the opening, closing, controlling, and safeguarding of electrical apparatus during key processes such as power generation, transmission, distribution, and conversion. Its foremost mission is to guarantee flawless operation and protection across a spectrum of power systems, making it a critical asset for modern electrical needs.
Structure
High voltage switchgear boasts an intricately designed structure featuring distinct compartments including the busbar room, circuit breaker room, secondary control room (commonly referred to as the instrument room), and feeder room. These compartments are securely isolated by robust steel partitions. Specifically, in the KYN28A-12 model, the instrument room is poised at the top, the circuit breaker room holds the central position, and the cable room is strategically situated at the bottom, ensuring a well-organized and efficient layout.
Low voltage switchgear is ingeniously classified based on the component installation method into fixed and dynamic drawer types. The drawer type switchgear is characterized by a sturdy fixed cabinet body, paired with a versatile and adaptable movable device section, allowing for flexibility and ease of use.
Internal Components
The switchgear's internal landscape is defined by pivotal components such as circuit breakers, isolating switches, and load switches, alongside sophisticated operating mechanisms, transformers, and a suite of advanced protective devices. These elements are seamlessly harmonized to ensure operational excellence and unwavering safety.
Classification
Switchgear can be expertly classified by the installation method of the circuit breaker into the highly adaptable movable type and the steadfast fixed type. Cabinet structures are distinguished as open, metal enclosed, or metal enclosed armored. Voltage levels further categorize them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories, while voltage waveform segregates them into AC and DC types. Additionally, they fulfill specialized roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and beyond, catering to specific functional needs.
Effect
Control Function: This function masterfully manages circuit connectivity to enable the precise start and stop operations of power equipment, ensuring impeccable control and optimal performance every time.
Protection Function: Offers unwavering protection by automatically severing the circuit in instances of overloads, short circuits, or leakage events, thereby safeguarding both equipment and personnel from potential hazards with utmost reliability.
Application Location
This switchgear is the ideal choice for deployment across a wide array of locations including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings. It stands ready to deliver reliable and consistent performance across these varied environments, ensuring peace of mind and efficiency.
