Ruilongyuan Electronic Ceramic Gas Discharge Tube is currently the most widely used lightning protection device. Whether it is lightning protection for AC or DC power supply or lightning protection for various signals, it can play a very good role. Voltage protection function. Ceramic gas discharge tubes are widely used in circuit protection solutions. Ceramic gas discharge tubes include chip ceramic gas discharge tubes, plug-in ceramic gas discharge tubes, diode ceramic gas discharge tubes and triode ceramic gas discharge tubes. The voltage range is from 75V to 3500V. , more than one hundred specifications; the ceramic gas discharge tube is sealed in a ceramic package, and is internally composed of two or more metal electrodes with gaps, filled with inert gases argon and neon. When the voltage applied to the two electrode terminals reaches When the gas in the ceramic gas discharge tube breaks down, the ceramic gas discharge tube begins to discharge and changes from high impedance to low impedance, causing the surge voltage to quickly short-circuit to nearly zero voltage and releasing the overcurrent into the ground, thus causing damage to subsequent circuits. to a protective effect.
Applications of ceramic gas discharge tubes:
1. Ceramic gas discharge tubes as protective devices
If your lines, equipment or components cannot withstand higher than You can use ceramic gas discharge tubes to protect them from transient overvoltage impacts of normal operating voltage (such as lightning, induced voltage, operating overvoltage, etc.). The following are typical applications:
A , signal protection
·In electronic circuits, expensive components such as integrated blocks, thyristors, chips, and circuit boards require the use of ceramic gas discharge tubes.
·Signal lines and network cables in telecommunications networks , telephone cards, switches, fax machines, telephones, distribution frames, junction boxes, base stations, and mobile phone antennas require the use of ceramic gas discharge tubes.
·Computer system hosts, modems, data processing systems, Long branch lines, short branch lines and various terminal equipment all require the use of ceramic gas discharge tubes.
·Video systems, CATV equipment, cathode ray tubes (CRT) require the use of ceramic gas discharge tubes.
·Ceramic gas discharge tubes are required for experimental equipment and testing equipment.
·Ceramic gas discharge tubes are required for various household appliances.
B , Power supply protection
It is recommended to choose the corresponding medium, high and ultra-high flow capacity series ceramic gas discharge tubes..
·Power supply lightning protection for various equipment (from a few volts to several Kilovolts) require the use of ceramic gas discharge tubes.
·Power sockets, power converters, plug-ins, air switches, load switches and other low-voltage appliances require the use of ceramic gas discharge tubes.
·Railway power and electrical systems require the use of ceramic gas discharge tubes.
·LC equipment, motors, and submersible pumps require the use of ceramic gas discharge tubes.
·Transmission equipment waste Surge voltage protection requires the use of ceramic gas discharge tubes.
