LUGAO supports customized services and integrates the most suitable solutions according to the different needs of customers. High Voltage Switchgear is used in power systems with a rated voltage greater than 3.6KV, serving functions such as power distribution, protection, and control to ensure grid stability. It is equipped with high-performance VS1 and VN2 series medium-mounted high-voltage AC vacuum circuit breakers and molded vacuum switches. The secondary circuit is configured with advanced control and protection components, and the busbar adopts an epoxy-coated insulation method. It operates stably and is safe and convenient.
1. Rapid disconnection
With a millisecond-level disconnection time in conjunction with a circuit breaker, it quickly cuts off short-circuit currents to avoid affecting circuit operation.
2. Superior environmental adaptability
The cabinet is made of high-quality aluminum-zinc coated steel plates, which are corrosion-resistant and highly durable. It can operate stably even in high-altitude regions, and internal heating devices can be installed to cope with extremely cold weather.
3. Space-saving and Easy Maintenance
The compact overall design minimizes space requirements, enabling quick installation and deployment. Remote monitoring of equipment status reduces labor costs.
4. Operational Safety
Equipped with a five-prevention interlock system, the primary side features a fully sealed design for contact protection, and a live voltage indicator provides visual confirmation.
The inspection and maintenance cycle for equipment/components (such as wear parts) depends on factors such as operating time, frequency of operation, and fault interruption conditions. Based on operating conditions and on-site
environment, switchgear should be inspected and maintained every 3 to 5 years.
• Inspect the operational status of the circuit breaker and operating mechanism in accordance with the vacuum circuit breaker manual, and perform necessary adjustments and lubrication;
• Inspect the operational status of the entire process of the draw-out mechanism moving in and out, and perform adjustments and lubrication as needed;
• Inspect the interlocking devices for flexibility and reliability; make adjustments and lubricate as needed;
• Inspect the contact surfaces of moving and stationary isolating contacts for damage, verify that the insertion depth meets requirements, check for reduced spring pressure, and inspect for abnormal oxidation of surface coatings; replace outdated conductive grease on isolating contacts;
• Inspect the contact conditions of busbars and all conductive connections, tighten connections as needed, and address any surface overheating issues;
• Inspect the grounding circuit components, such as grounding contacts, main grounding wires, and door-crossing grounding wires, to ensure their electrical continuity;
• Wipe dust from the surfaces of vacuum arc extinguishers and insulating components with a soft cloth. If condensation causes partial discharge, apply a thin layer of silicone grease to the discharge surface as a temporary repair.
