1. no need to consider the load current, modular installation, easy to maintain the built-in temperature control and overcurrent circuit breaker technology, high safety performance, no continuous flow;

2. the indicator window green is normal, red indicates failure, prompt replacement, clear and changeable;

3. The remote signal detection interface (dry contact point) is used to realize the remote monitoring work state.

4. The and three groups of high performance chips are more efficient and safer using the variable working conditions of the fan.

According to IEC62305 series standards and IEC61400-24's protection requirements for various special parts of fans, it is necessary to consider the installation and selection of lightning protection sub area SPD for wind power generation system.

1. lightning protection area (LPZ 0... 3);

2. SPD conforms to the test current waveform (8/20us waveform and 10/350us waveform, etc.);

3. the level of voltage protection (Up value of SPD);

4. Voltage and mode of power supply system (230/400V and 400/690V system, TN and TT etc.);

5. harmonic interference and so on.

1. IEC62305《lightning protection》 series of standards;

2. IEC61312《protection of lightning electromagnetic pulse》

3. IEC61400-24 《lightning protection of wind power generation system》;

4. IEC61643-11《surge protector to low voltage distribution system》;

5. GB50057 《code for the design of lightning protection for buildings》.
