Spark Gap Details TRIZ Cases

A separating device splits upon varistor failure, restoring basic impulse level and providing visual indication for maintenance.

A surge arrester integrates a switching unit with fixed contacts that enter a quasi-closed state during surges to block leakage currents.

A pluggable surge arrester uses segmented plug-in contacts with stabilizing offsets to manage high current loads.

A current-compensated choke minimizes power loss during normal operation by canceling magnetic fields through opposing windings.

A surge protection device uses a short-circuit-proof fuse box in the secondary current path to isolate potentials and protect components.

A pressure-sensitive switch detects internal housing pressure from arcs to short-circuit conductors and trigger upstream overcurrent protection.

Thermally softenable holding devices trigger resistive separation mechanisms that dissipate stored magnetic energy without causing voltage spikes.

A disconnector device uses a labyrinth ventilation system to contain hot gases and sparks generated during rapid current interruption.

Flashover path converts combustion gases into electrical breakdown to rapidly trigger the series fuse, preventing varistor thermal destruction and fire hazards.

A biasing assembly moves the containment shield away from the conductor base to vent arc gases and prevent excessive ground path current.

Integrating a tubular MOV and ceramic GDT into one unit limits follow-on currents and prevents short circuits during voltage spikes.

A pulse power device uses an annular electrode and cantilevered core electrode to generate stable arc discharge.

Asymmetric electrode positioning prevents energy loss and wear by directing arcs away from connecting arms.

A surge current detection device concentrates magnetic flux to visualize penetration states using microcapsule technology.

Discharge auxiliary electrode uses metal and semiconductor grains bound by glass material to form stable ESD protection structures.

Electronic monitoring replaces mechanical switches to detect module presence, reducing manufacturing complexity and wear.

An arrester uses a short-circuit mechanism to switch electrode states and manage electrical connections.

Dual chambers contain hot ionized gas from the arc chamber, preventing mains follow current damage while maintaining compact housing volume.
