Description

Surge protector

Technical Field

The utility model relates to a surge protector, and belongs to the field of electrical elements.

Background

The surge protector, also called lightning protector, is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines. When a peak current or voltage is suddenly generated in an electric loop or a communication line due to external interference, the surge protector can conduct shunt in a very short time, so that damage of the surge to other equipment in the loop is avoided.

The power supply surge protector is divided into an explosion-proof box type and a module type. A varistor with excellent nonlinear characteristics is adopted. Under normal conditions, the surge protector is in an extremely high resistance state, and leakage current is almost zero, so that normal power supply of a power supply system is ensured. When the power supply system is subjected to surge overvoltage, the power supply surge protector is immediately conducted in nanosecond time, the amplitude limit value of the overvoltage is in the safe working range of the equipment, and meanwhile surge energy is released. Then, the surge protector quickly changes into a high-resistance state, so that normal power supply is not affected.

The existing surge protector only uses piezoresistors to protect, in the long-term use process, the connecting stability of the mode is poor, the passing current is small, and because the size of the piezoresistors is too large, the indicating structure cannot be installed, and the surge protector needs to be checked manually and is inconvenient.
