Product Description
Switchgear: The Essential Electrical Equipment. A switchgear is a pivotal electrical apparatus designed for efficient opening, closing, controlling, and safeguarding electrical equipment across the entire power system spectrum – from generation to transmission, distribution, and energy conversion.
Structure
High Voltage Switchgear: Typically encompasses a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is isolated with robust steel plates. For instance, the KYN28A-12 model features an upper instrument room, a middle circuit breaker room, and a lower cable room, ensuring optimal organization and safety.
Low Voltage Switchgear: Available in fixed and drawer types, distinguished by component installation methods. The drawer type switchgear integrates a fixed cabinet body with a movable device part, offering flexibility and convenience.
Internal Components
Comprehensive Internal Components: Includes essential circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a diverse array of protective devices, ensuring seamless operation and safety.
Classification
Versatile Classification: Based on circuit breaker installation methods, categorized into movable and fixed types. Structurally, it divides into open, metal enclosed, and metal enclosed armored types. Voltage-wise, it segments into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Voltage waveform classification includes AC and DC switchgear. Functional division encompasses incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Master the ability to connect and disconnect circuits, facilitating start-stop control of power equipment seamlessly.
Protection Function: During circuit anomalies like overloads, short circuits, or leakages, it autonomously interrupts the circuit to ensure the safety of both equipment and personnel.
Application Location
Diverse Application Locations: Ideal for power plants, substations, petrochemicals, metallurgical steel rolling industries, light industry textiles, factories, mines, residential areas, high-rise buildings, and beyond, offering unmatched versatility and reliability.
