High-voltage circuit breakers generate significant mechanical stress during opening and closing operations. These shocks not only affect the breaker mechanism itself but also place heavy demands on the internal control components. Without proper design, such conditions threaten the stability and safety of the entire control system.

Critical Risks

Contact instability: Mechanical shock may cause relay contact bounce, leading to unintended triggers in control circuits.
Structural degradation: Prolonged exposure causes displacement, loosening, or fracture of internal parts, resulting in functional failure.
Accelerated fatigue: Frequent shock accelerates component wear-out, shortens service life, and raises maintenance costs.

ODES Technical Solution

To mitigate these risks, ODES has developed relays and control modules specifically qualified for breaker shock conditions, with proven resistance up to 20 g mechanical vibration and shock levels.

Core Advantages

Shock-resistant design: Advanced structural reinforcement ensures stable electrical performance under breaker-induced stress.
Optimized configuration: Component selection and layout tailored to breaker vibration spectra and installation constraints.
Independent validation: Type-tested by an accredited German laboratory for vibration and environmental endurance, guaranteeing long-term field reliability.

Engineering Applications & Customer Value

ODES relays have been deployed in numerous projects worldwide where breaker operation imposes severe mechanical demands:

Installed in breaker and disconnector operating mechanisms as critical control elements.
Proven reliable under sustained harsh-duty conditions, recognized by OEMs and utilities alike.

Customer Benefits

Eliminate misoperations and outages caused by mechanical shock.
