• Magnetic mechanisms: Generally low maintenance, but the solenoid and electrical connections should be inspected periodically.

Summary:

• Maintenance requirements depend on the mechanism type.

• Spring and hydraulic mechanisms require more mechanical upkeep; motor-driven units need electrical checks.

• Magnetic mechanisms are low-maintenance but still require periodic inspection.

• Spring mechanisms are cost-effective; hydraulic, motor-driven, and magnetic types are more expensive.

• Choice should be based on technical requirements, not just initial cost.

Impact na Environment Don Kiyasai Aiki Na Circuit Breakers

Different mechanisms have varying environmental impacts:

• Spring mechanisms: Minimal environmental impact — they rely on mechanical energy with no fluids or emissions.

• Hydraulic mechanisms: Risk of oil leakage, which can cause soil and water contamination. Hydraulic fluid disposal must be managed carefully.

• Motor-driven mechanisms: Consume electrical energy, contributing to operational energy use and carbon footprint.

• Magnetic mechanisms: Generally eco-friendly, but energy is required to generate the magnetic field.

Summary:

• Environmental impact varies by mechanism.

• Hydraulic systems pose leakage risks; motor-driven systems increase energy consumption.

• Magnetic mechanisms are environmentally friendly, though energy use should be considered.

Summary: Reliability of Spring Mechanisms in High-Voltage Applications (35kV and Above)

For high-voltage circuit breakers (35kV and above), spring mechanisms are structurally simple and theoretically more reliable. However, recent power grid operation experience shows that spring mechanisms are not without issues, including:

• Spring fatigue leading to incomplete opening/closing

• Latching component jamming causing failure to operate

• Shaft-hole deformation altering tripping characteristics, resulting in maloperation or failure

Additionally, BLK-series coiled springs have shown cases of spring fracture due to poor environmental tolerance (e.g., temperature, humidity).

To detect defects in breakers and their mechanisms during routine testing, extensive research has been conducted worldwide. While many testing devices and analytical methods exist, using test signals and advanced analytics to assess and improve mechanism reliability remains a challenging and ongoing task.
