Functional Advantages

DISCONNECTION AND ISOLATION FUNCTIONS
Without an arc-extinguishing device, it cannot be opened or closed under load. Its primary function is to create a clear break, isolating high-voltage power and ensuring the safety of maintenance personnel. This is the core function of a disconnecting switch.

COMPACT STRUCTURE, SUITABLE FOR INDOOR INSTALLATION
Small size and light weight, specifically designed for high-voltage switchgear (such as KYN28, XGN15). It can be mounted upright or side-mounted, saving cabinet space.

STABLE MECHANICAL AND ELECTRICAL PERFORMANCE
Mechanical life can reach thousands of cycles. Contact pressure is stable, contact resistance is low, and long-term operating temperature rise is low. Insulation components meet national standard requirements for power frequency withstand voltage and lightning impulse tests, suitable for dry/slightly humid indoor environments.

ADAPTABLE TO MULTIPLE OPERATING MODES
Can be equipped with a manual operating mechanism (CS6-1 type). Some models can be upgraded to electric/spring operating mechanisms, supporting remote control and interlocking protection.

EASY MAINTENANCE
Simple structure, contacts, and insulators are easy to inspect and replace, requiring no complex arc-extinguishing maintenance, resulting in low operation and maintenance costs.Core Applications
Power System Maintenance Safety Isolation
In 10kV-35kV indoor power distribution systems, this switch, used in conjunction with circuit breakers, creates a clear disconnect after the circuit breaker trips, preventing accidental energization and ensuring the safety of switchgear and busbar maintenance.Switching Power Distribution Operation Modes
In dual-power supply systems, the disconnect switch switches busbar connections to achieve power switching and a segmented power supply, ensuring power continuity.Small Equipment/Unloaded Line Switching
It can switch voltage transformers, surge arresters, unloaded busbars, and short-distance unloaded cable lines (low-current unloaded conditions).Complete Switchgear Sets
As a standard component of indoor high-voltage switchgear, it is widely used in:
Urban/factory power distribution rooms, prefabricated substations
Power distribution systems in industrial and mining enterprises, hospitals, and schools
Indoor power distribution links in new energy power plants (photovoltaic/wind power).Additional Precautions:
It is strictly forbidden to open or close indoor high-voltage disconnect switches under load, as this will generate a strong electric arc, causing equipment burnout or safety accidents.When selecting a switch, it is necessary to match the rated voltage (12/24/35kV), rated current (400-2000A), dynamic and thermal stability current, and other parameters to ensure compatibility with the switchgear and system operating conditions.

FAQI. Company and QualificationsQ1: What products does Henan Jiatong Electric produce?

Common Questions about Vacuum Circuit BreakersQ4: What is the difference between indoor and outdoor circuit breakers?
A: Indoor circuit breakers (VS1/VD4 series) use epoxy resin insulation and steel plate cabinets, featuring a compact structure suitable for indoor switchgear use and offering high cost-effectiveness. Outdoor circuit breakers (ZW series) use silicone rubber composite insulation and stainless steel enclosures, providing waterproof, sunproof, anti-flashover, and salt spray resistance, allowing for all-weather use on outdoor poles.
Q5: What is the service life and maintenance-free period of a vacuum circuit breaker?
A: Conventional vacuum circuit breakers have a mechanical life of over 10,000 cycles. The arc-extinguishing chamber maintains a stable vacuum, enabling long-term maintenance-free operation under normal conditions. Only annual routine inspections, bolt tightening, and insulation cleaning are required.Q6: Can circuit breakers be used for frequent opening and closing?
A: Yes. Vacuum circuit breakers have excellent arc-extinguishing performance and no risk of combustion or explosion, making them ideal for frequent switching of transformers, capacitors, and motor loads. They are currently the mainstream switching equipment in power distribution systems.III. High-Voltage Disconnect Switch/Grounding Switch Related IssuesQ7: What is the difference between a disconnect switch and a circuit breaker?
A: Circuit breakers are used for load switching and fault short-circuit protection; disconnect switches do not have arc-extinguishing functions and are mainly used for voltage isolation, creating a clear break, and ensuring maintenance safety. The two must be used together.Q8: What are the special advantages of generator outlet disconnect switches?
A: Specifically designed for generator outlet operating conditions, they feature high current, vibration resistance, high insulation, and strong dynamic and thermal stability. They are suitable for frequent operating conditions in power plants and generator sets, ensuring stable operation and high safety.IV.
