JPK-6-WF High Voltage Relay DC25KV Carry 75A Current Vacuum Relay Switch Make & Break Load Switching
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.
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.
Install
1. During the transfer or assembly process, the ceramic vacuum relay may adsorb conductive salt and other dirt (such as hand sweat) on the surface of the ceramic shell. These dirt will reduce the high-pressure performance of the product, which may cause the surface of the ceramic vacuum relay to arc or leak. Current. Therefore, it is best to keep the ceramic surface clean during use.
2. Avoid causing the ceramic vacuum relay to be impacted. The impact may cause the ceramic vacuum relay to leak, change parameters, and fail.
3. Due to the slight deflation of the material, the vacuum ceramic vacuum relay may generate 1-2 times of tiny inrush current when the high voltage is applied between the disconnected contacts or the contacts to the outer casing after being stored for a period of time. Avoid this current to damage the coil supply line. Ground the case when installing the ceramic vacuum relay.
4. Ceramic vacuum relays mainly have two fixing methods, one is flange mounting and the other is thread mounting. Be careful not to subject the sealing and connecting parts of the ceramic vacuum relay to lateral or torsional forces during installation.
