A：The core components DSP of Lafaelt DVR is from Texas Instruments TI dual-core processor. Dual-core operates in parallel, with high data processing speed and fast response time. The full response time is less than 1ms. The cabinet adopts a distributed control structure without a main control unit, which truly achieves module redundancy design. The man-machine interactive window adopts MS Windows system, and records more than 10 thousand SAG events and waveforms. 

The cabinet certification test: the salt spray test, high and low temperature cycle test, 400V system 600KVA model certification.

A：The core components of Lafaelt reactive power filter are all from worldwide famous brand. For example, DSP comes from Texas Instruments TI dual-core processor. The dual-core operates in parallel, with high data processing speed and fast response time. The full response time is less than 5ms. And it also has outstanding features in terms of performance, for example, it can filter out 2-51 times harmonics, 1.2 times overload capacity, the overall efficiency exceeds 97%, and the harmonic control rate is higher than 95%.

The advantage of the cabinet certification experiment: 5,000m high altitude, 72 hours salt spray test, earthquake resistance at level 8, and the professional certification from TLC. 

A：1、The whole roll of silicon steel of WISCO(Wuhan Iron and Steel Group) is used, the thickness tolerance is within +/-0.01mm. It has the features of low iron loss and high magnetic induction. 

2、Lafaelt reactor has high linearity, the drop of inductance is no more than 5% under the 1.8 current.

3、Good raw materials and product structure ensure the temperature rise of Lafaelt reactors less than 55 centigrade and the operation noise lower than 50bB.

A：1、The high-temperature film made by Terofan Germany is used. The film thickness is only 8.5um, and it can withstand high temperature about 115 centigrade, and prevent break-down effectively. Other manufacturers basically used China domestic made 7um film, which performs poorly on temperature resistance. 

2、Lafaelt capacitors use Swiss made automatic winding machine. The flatness and tightness of the winding film are evenly achieved, the damage is small during the winding process and the film is not easy to break down. 

3、Lafaelt capacitors have 1.8 times of long-term overcurrent capacity, which is far exceeding the national standard of 1.3 times, and it suppresses the influence of harmonics on capacitors more effectively. 

4、In addition to the pressure tension explosion-proof device, the Lafaelt capacitor also has a temperature protection node. After connecting the node to secondary control circuit loop, when the temperature of the capacitor is too high, the whole circuit will be cut off to protect the capacitor. 

5、The capacitor filling medium is black glue, which is solid state at normal temperature, and will become suspended and mixed state when the temperature reaches over 85 centigrade, to facilitate the release of gas pressure inside the capacitor, then to make effective action of the pressure valve, and to effective protect the capacitor and prevent the expansion of the accident. 

Lafaelt capacitor is certified for 750 hours aging test, 1000 continuous charge-discharge cycle tests, and 200 thousand hours’ life test.
