Basic Overview and Lightning Protection Principle of Lightning Surge Protector

 


A lightning surge protector is a special power protection device dedicated to preventing lightning surge damage in low-voltage power distribution systems. Thunderstorm weather will generate direct lightning strike and induced lightning surge, forming instantaneous high voltage and strong surge current in power lines. This kind of high-energy lightning surge far exceeds the withstand voltage of ordinary electrical equipment, easily causing large-scale equipment burnout and circuit paralysis. The core function of lightning surge protector is to absorb lightning surge energy and protect power systems from lightning damage.

The lightning protection working principle of lightning surge protector is targeted and efficient. Under normal weather conditions, the device is in a high-resistance standby state, which does not affect the normal power supply of the circuit. When lightning strikes induce surge overvoltage on the line, the lightning surge protector instantly conducts, quickly releases lightning surge current to the ground, and clamps the line voltage within the safe range of electrical equipment. After the lightning surge disappears, the device automatically resets to realize repeated lightning protection.
SWGCT lightning surge protector provides professional lightning surge suppression for power distribution systems.

Different from ordinary surge protectors, lightning surge protector has higher energy absorption capacity and stronger impact resistance, which can cope with high-energy surge pulses generated by lightning induction and direct lightning strikes. It is divided into multiple protection levels, which can form hierarchical lightning protection systems for buildings, industrial parks and infrastructure. It is an essential safety device for lightning protection engineering in modern electrical systems. SWGCT high-energy lightning surge protector resists strong lightning surge impact for power system safety.

Working Principle and Key Applications of High Precision Encoder

Image
High precision encoder follows the classic rotary sensing principle, transforming mechanical rotation into recognizable digital electrical signals through internal induction structures. Compared with ordinary encoders, it upgrades core materials and production craftsmanship to greatly lift detection accuracy and signal stability. Based on signal output modes, high precision encoders are divided into incremental type and absolute type. Incremental models are mainly used for real-time speed monitoring, while absolute types can store position data permanently. The two categories cater to different high-precision control requirements and cover most sophisticated industrial control scenes. Sensyor Electric high precision encoder supplies a full range of categorized products to satisfy various application needs. It provides solid shaft, hollow shaft and through-hole installation styles, adapting to different assembly environments of precision equipment. Every model is strictly calibrated du...
