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.
The fusewas invented by Edison more than 100 years ago to protect the expensive incandescent lamp. With the development of The Times, fuses protect electrical equipment from the current overheating injury, avoid electronic equipment due to internal failure caused by serious injury. When electric current flows through a conductor, the conductor will heat up because there […]
The system for protecting a building against the effects of lightning must include: =protection of structures against direct lightning strokes; =protection of electrical installations against direct and indirect lightning strokes. The basic principle for protection of an installation against the risk of lightning strikes is to prevent the disturbing energy from reaching sensitive equipment. To […]
DC Surge protective device,protect against lightning surge voltages in solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and incerter/converter […]
