Product Description
A switchgear serves as a pivotal electrical apparatus designed to efficiently orchestrate the opening, closing, controlling, and safeguarding of electrical devices during the crucial phases of power generation, transmission, distribution, and energy conversion.
Innovative Structure
High Voltage Switchgear: This sophisticated assembly typically comprises a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room, each meticulously isolated with durable steel partitions. For example, in the KYN28A-12 model, expect an elevated instrument room, a centrally located circuit breaker room, and a strategically positioned cable room at the base.
Low Voltage Switchgear: Based on the component installation method, this type is categorized into fixed and drawer types. The drawer type features a sturdy fixed cabinet housing a versatile, movable device section.
Comprehensive Internal Components
The internal ensemble prominently includes circuit breakers, isolation switches, load switches, operational mechanisms, transformers, and an array of advanced protective devices.
Diverse Classification
Classification by installation method places circuit breakers into movable and fixed categories; cabinet structures are classified as open, metal-enclosed, and metal-enclosed armored types. Voltage level categorization distinguishes high-voltage switchgear (above AC1000V) from low-voltage switchgear (below AC1000V). Additionally, the distinction based on voltage waveform presents AC and DC switchgear, while purpose-driven classification highlights incoming, outgoing, metering, and compensation cabinets.
Significant Effect
Control Function: The switchgear adeptly facilitates the connection and disconnection of circuits, enabling seamless start-stop control of power equipment.
Protection Function: In events of overload, short circuit, leakage, or other faults, it automatically severs the circuit, ensuring the utmost safety of both equipment and personnel.
Strategic Application Location
Perfectly suited for deployment in power plants, substations, petrochemical facilities, metallurgical steel industries, light industrial textile operations, various factories and mines, residential communities, and towering high-rise buildings.
