Product Description
Power surge protector, also known as the power supply lightning protection, for AC 50/60HZ, rated voltage 220V/380V power supply system, the impact of indirect lightning and direct lightning or other transient overvoltage surge protection, applicable to family homes, the third sector and industrial areas of surge protection requirements, with relative phase, relative to the ground, relative to the center line, the center line to the ground and its combination of protection modes.
The role of the protector
Power surge protector is usually connected in parallel to the circuit system, when lightning occurs, in the building into the various types of metal tubes and lines generated by the high-intensity electromagnetic induction, thus generating a large number of pulse energy, the power surge protector will play a role in the overcurrent into the earth, reducing the potential difference between the ports of equipment. Suitable for 220/380V power supply and distribution system transient overvoltage protection, the product can and its effective suppression of lightning-induced induction overvoltage and system operation overvoltage, protection of equipment safety, to protect the normal operation of the system.
Technical parameters
Working principle
Power surge protector is divided into two types of explosion-proof box type and modular type. All use a non-linear characteristics of an extremely good voltage sensitive resistor. Under normal circumstances, the surge protector is in a very high resistance state, leakage current is almost zero, thus ensuring that the power supply system normal power supply. When the power system surge overvoltage, the power surge protector immediately in the nanosecond time on, the overvoltage amplitude limit in the safe working range of the equipment, while the surge energy into the ground to release off. Subsequently, the surge protector and quickly change to a high resistance state, so as not to affect the normal power supply.
