Surge protective decives, also known as lightning arresters, are electronic device that provide safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication lines due to external interference, thesurge protective decives can conduct the shunt in a very short period of time, thereby avoiding the damage of the surge to other equipment in the circuit. The surge protective decives are suitable for the requirements of surge protection in domestic residential, tertiary industry and industrial fields. The followings are the features of surge protective decives.
1. The protection flow of the surge protective decives is large, the residual pressure is extremely low, and the response time is fast.
2. The surge protective decives adopt the latest arc extinguishing technology to completely avoid fire.
3. The surge protective decives adopt temperature control protection circuit and built-in thermal protection.
4. The surge protective deciveshave power status indicators to indicate the working state of the surge protectors.
5. The surge protective decives have rigorous structure and stable and reliable performance.
Circuit breakers are necessary, and many experts need them to prevent circuit fire caused by short circuit current. Miniature circuit breakers are known to protect only from voltage spikes for a short period, whereas the circuit breaker protects overcurrent in the wiring. If there is over-voltage, it can damage the appliance. However, over-voltage will not […]
Voltage protection is an important electrical protection method that aims to ensure that equipment in the power system can operate safely when the voltage is abnormal. When the voltage in the power system is too high or too low, exceeding the range that the equipment can withstand, the voltage protection will trigger the protection mechanism and […]
DC Surge Protection Device ( DC SPD) is designed to limit transient over voltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this over voltage to a value that is not hazardous for the electrical installation and electric switchgear. Type 2 DC Surge Protection Device ( DC SPD): […]
