How to select SPD?

 

The first level of power protection:
According to the requirements of national standards: in the main distribution box of the power supply should be installed Ⅰ level test surge protector. The voltage protection level of the surge protector shall be less than or equal to 2.5 kV. The value of the impulse current of each protection mode, Iimp, shall be equal to or greater than 12.5 kA when in uncertainty. Therefore, the lightning protection box of the first stage power supply should choose products with T1 test parameters (10/350μs test waveform), and the impulse current Iimp is ≥12.5kA.
The second level protection of power supply: the second level selection of T2 test (8/20μs test waveform) parameters of the product, the maximum flow capacity (IMAX) : 40kA or 80kA, nominal flow capacity (IN) : 20kA or 40kA can be. Three-phase electric selection of 4P, single-phase electric selection of 2P structure.

The third level protection of power supply:

the third level lightning protection environment is generally single-phase electricity, select T2 test (8/20μs test waveform) parameters of the product, the maximum flow capacity (IMAX) 20kA, nominal flow capacity (IN), the maximum continuous working voltage 275VAC, protection level Up:1.2kA

 

 

Scope of application:
Second power lightning protection box is mainly installed in the floor distribution, room distribution and other environments, as the second level of lightning protection of the distribution system, release the remaining surge, with the first level of lightning protection box, to meet the requirements of lightning protection acceptance and protection needs.

 

 

Structure and Principle:
Lightning protection box in parallel to the protected equipment front-end, under the condition of normal operating voltage,
power supply lightning protection box in a high impedance state, does not affect the normal work of the circuit. When there is
pulse surge line lightning strike, power lightning protection box in the nanosecond time conduction, quickly put the overvoltage
of diarrhea in the earth, when the pulse over-voltage disappears, power lightning protection box and automatic recovery to a
high resistance state, does not affect the line power supply.

 

 

Installation location:

The power distribution system shall adopt a grading configuration according to the standard requirements. The first level protection shall be able to withstand most of the lightning current and pass the T1 lightning shock test. The second level protection shall be configured to discharge the residual lightning current, limit the residual voltage at the equipment end, and cooperate with the first level protection.
