What Are the Advantages of the Surge Protection Device?

Ⅰ. Functions of the SPD surge protector


The surge protector safety inspection instrument is designed to meet the routine and regular rapid detection of surge protectors. It is a new type of special instrument that integrates a variety of instrument test functions. Its main functions include continuity test function, insulation resistance test function, varistor voltage and leakage current test function of voltage-limiting lightning protection component, ignition voltage test function of ignition lightning protection component, online ammeter function, etc.


When inspecting lightning protection facilities, people often carry instruments such as multimeters, insulation resistance testers, DC surge protection device testers, and ammeters. Surge protectors can replace these instruments. Because the surge protector is easy to carry, easy to operate, fast in measurement, and convenient for the work of the inspector, it has a certain market share in the meteorological system.


Ⅱ. What are the classifications of the SPD surge protector?


1. Power surge protector


2. Signal surge protector


Ⅲ. What are the advantages of the SPD surge protector?


SPD surge protector is an indispensable device for lightning protection of electronic equipment. It used to be called "lightning arrester" or "overvoltage protector". The function of this equipment is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand. Or let the powerful lightning current flow into the ground to protect the equipment or system from impact and damage.


1. A wide range of surge protectors can protect all common signals;


2. A variety of models and connection technologies are available for flexible application;


3. The pluggable surge protector is easy to maintain;


4. Pluggable lightning protection device is suitable for explosive areas;


5. The surge protection device suitable for the MCR system is a part of the COMPLETE line system;


6. The discharge tube has no follow-up current, and the service life of the surge protector and electrical device is long;


7. The surge protector has a built-in backup protection fuse, which can reduce the workload of wiring and shorten the length of the cable;


8. Compact design saves installation space.


Shanghai Chenzhu Instrument CO., LTD. has more than 24 years of experience in the design and manufacture of intrinsic safety barriers, signal conditioners, surge protection devices, safety relays, power transmitters and temperature transmitters.
