Arrester coaxial type surge protector
The classification of the genus: lightning series >arrester lightning arrester
Number: 929
Specification: C series
Type: coaxial type surge protector
The wireless transceiver system is usually regarded as particularly sensitive to surge voltage. The antenna cable across the buildings are usually very long, and the antenna itself directly exposed to the air, therefore, need to use the wire has a coaxial structure and according to the characteristics of EMC technology. Even so, still can not prevent dangerous coupling surge voltage antenna cable and sensitive interfaces of the transceiver system form the parasitic voltage. However, to improve the safety of the transceiver by surge voltage protection device, which almost never because of damage caused by transient voltage surge. These protective measures is to improve the specific device availability and operability.
Wireless communication system and a mobile telephone system
The transmission path can use radio link system to the cable bridge. Using this method, for example, a data processing device is only temporary use, also can communication. A coaxial cable is connected to a transmitter and a receiver with a BNC or N type joint of the. By protecting the device adapter structure can be easily inserted into the corresponding joint. Because the device adopts high transmission frequencies in the antenna work, therefore, gas discharge tube was used as a crude protection level.
Local communication
The radio system was used in all business areas. Fire and emergency services using the wireless communication technology. Amateur radio operators use a lot of radio system. The antenna mechanical connection is usually carried out by UHF or N joint. Surge voltage protection device is connected with such a system. Due to high transmission frequency, composed of powerful gas discharge tube protection circuit design of a single stage.
Video communication
In building security and defense fields, using the camera for monitoring. Because the equipment site usually in the exposed position, therefore, need a surge voltage protection device to ensure the availability of the camera. Coaxial surge voltage protection device with coarse and fine protection.
Broadband cable and terrestrial antenna
When in the vicinity of broadband cable lightning occurs in the underground installation, or into a receiving antenna for television or radio, surge voltage may be coupled to the antenna cable. In this case, the existence of risk destroying the broadband amplifier, TV, radio antenna entrance. For this situation the surge voltage protection device is designed with the adapter complying with the requirements of DIN 45325 TV and radio connector.
