The ceramic vacuum relay is a ceramic vacuum seal that isolates the
contact point seal of the relay from the outside air to obtain a
high withstand voltage for high-voltage relays, which are commonly
used in high-voltage circuits. The vacuum seal makes the relay less
prone to arcing. Under ideal conditions, the vacuum is likely to
reach a dielectric strength of 10000V per 0.1 mm. In addition,
since there is no air, the contacts in the vacuum are not oxidized,
so the contact resistance of the vacuum type relay is small and
stable. Particularly suitable for use in RF applications. A typical
ceramic vacuum relay consists of four basic parts: a sealed arc
extinguishing chamber with a contact point inside the arc
extinguishing chamber for high pressure resistance. An armature
mechanism that moves the movable contact. Powered coil section. An
additional part that is easy for the user to install and connect.
Features:
vacuum has good arc extinguishing performance. The arc in the
vacuum is easily diffused and does not easily cause contact wear.
Therefore, the vacuum relay has a long life and can carry a load
switch. In summary, the vacuum relay has the characteristics of
high breakdown voltage, fast arc-extinguishing, large breaking
current, small volume, light weight and long service life. Widely
used in the field of weak current control, such as cardiac
pacemaker, magnetic resonance imaging, high-frequency antenna
coupling device, radar, capacitor discharge.
Application for Relays:
vacuum relays play a vital role when high power and low RF losses
are required.
