Divided Protector

Inverter system design Xiangjie Lightning

According to IEC1312-1 ~ 3 standard, to protect you Inverter System equipment, will need to protect the space is divided into different mine areas (LPZ), according to the different parts of space LEMP (lightning electromagnetic pulse mine) the extent and circumstances to establish the appropriate level of protection, rational use of the corresponding SPD .

An implementation plan Lightning protection system should be designed to meet the following principles:

1, Protector Does not affect the normal operation of the protected equipment;

2, when the shock wave generated by lightning, protection devices should be used in low impedance, the impact of current directly into the earth and not dangerous impact on the ground potential difference;

3, protective devices should have a higher ability to withstand impact energy and to regulate the earth system.

According to IEC1312-1 ~ 3 specification, inverter system to protect your equipment, will need to protect the space is divided into different mine areas (LPZ), according to the different parts of space LEMP (lightning electromagnetic pulse mine) is establish the extent and the corresponding actual level of protection, rational use of the corresponding SPD.

4, Power supply System: According to the statistics show that 80% of lightning is penetrated by the power line network equipment, to protect Electronic Equipment, need input in their power to set the power SPD before, so the city along the electric circuit can be hit from the lightning over-voltage leakage into the ground in advance.

2, Lightning Protection Design of Power Distribution System

Characteristics of the distribution system for inverter can be divided into three mine areas were to be considered. As mentioned above may give rise to single-stage lightning because lightning current discharge caused by excessive residual pressure after the excessive or insufficient protection due to equipment damage. Therefore, select the power system multi-level protection can prevent direct mine to the action from all levels of surge voltage of the invasion.

1, Power 1 Lightning LPZOA-LPZ1 area:

By "building lightning protection design," Chapter VI: IV 6.4.7 requires the nominal discharge current of each line should not be less than 15KA. Moreover, based on "Lightning in design," Chapter VI: Section IV 6.4.7 and IEC "Lightning electromagnetic pulse," the third part; surge protector requirements, surge protectors can be tens of thousands of V induced by lightning over-voltage limit to 4KV the following.

Sum should be 380V Low Substation power distribution equipment installed nominal total capacity of 25KA to 10/350 S Flow waveform (or 100KA the 8/20 S waveform switching) AOTEMATPORT/4P-B100 modular power surge protector for the whole All electrical equipment, power supply first-class protection.

2, Power 2 mine LPZ1-LPZ2 District :

Building Supply Distribution box Flow waveforms were installed 8/20 S capacity 20KA ~ 40KA of ATT385/4P-C40 three-phase power supply of Products.

3, Power 3 lightning LPZ0-LPZ3:

According to IEC61312-3 lightning electromagnetic pulse III: surge protector's request, LPZ2-LPZ3 District SPD Flow capacity (8/20 S): 10KA. Inverter power distribution box can be installed 8/20 S waveform respectively, current capacity 20KA ~ 40KA of ATT385/4P-C20 three-phase power supply of Products.

The Divided Realms, Book 2: The Darkening $9.99 Although life in a magical realm is anything but normal for Princess Willow Farrandale of Mistolear (formerly Willow Kingswell of Earth), she is doing her best to adjust. She is refining her skills at Mage School and spending time with her new friends, especially her sworn knight and protector Brand - despite the fact that he drives her mad with his old - fashioned rules about ''proper courtship.''The peace does not last, however, as a misstep in Clarion dooms Willow to play another twisted faerie Game. If she loses, faeries will once again be free to wreak havoc in the realms of Mistolear and Earth. The Game Master, King Jarlath of the Unseelie Court, throws Willow and Brand into the Goblin's Gauntlet where goblins, phookas, and a host of bloodthirsty creatures are on the hunt. In a surprising move, Jarlath sends his own children into the Game as well. Dacia, the female twin, is ruthless and cunning. Theon, the male, is clever, flirtatious, and, like all faeries, devastatingly beautiful. Willow struggles to resist Theon's charm, while Brand's jealousy simmers - but with the fate of two realms hanging in the balance, both must push their emotions aside. Can Willow and Brand trust the faerie siblings, or is there more than one Game being played?

Divided Staffs, Divided Selves $28 Ethical decision making in the context of conflicting values takes on a fresh immediacy when the self itself is in conflict. Divided Staffs, Divided Selves: A Case Approach to Mental Health Ethics brings the immediacy of a clinical case conference to a wide range of students and clinicians. The book provides both clinical case material and a method for engaging in a dialogue choices in the mental health care field. The essays that introduce the volume place the ethical problems of treating mentally ill people in the context of the health care ethics movement and traditions of ethical decision making. The individual cases arise from clinical and consultative experiences. This case material will serve as the basis for learning and reflection by clinicians in interaction with their colleagues, and it also will be especially valuable to students studying ethical concepts who do not have access to real-life cases or problems.

India Divided $12.95 In India Divided, environmental, human rights, and antiglobalization activist Vandana Shiva chronicles the internal battles of a nation that is both the world's largest democracy and a leading nuclear power. Shiva describes a society where traditional cultures collide with the new economy of globalization, and charts the course of India's war of fundamentalisms in the age of terror. From the IT centers of Bangalore to the villages of Uttar Pradesh, from the massacre at Gujarat and the popular emergence of Hindutva's narrow communalism to the decades-old battle for Kashmir, India Divided reveals a convergence of globalization and terrorism. Looking to the plights of India's Dalit communities and millions of poor subsistence farmers impoverished or displaced by biotechnology, seed patents, and the spate of mega-dam projects, Shiva argues that these silent killers form a local terror unmatched in devastation. In India Divided Shiva addresses India’s most urgent threats with gravity and hope.

The Divided Mind $11.99 The book that will change the way we think about health and illness, The Divided Mind is the crowning achievement of Dr. John E. Sarno's distinguished career as a groundbreaking medical pioneer, going beyond pain to address the entire spectrum of psychosomatic (mindbody) disorders. The interaction between the generally reasonable, rational, ethical, moral conscious mind and the repressed feelings of emotional pain, hurt, sadness, and anger characteristic of the unconscious mind appears to be the basis for mindbody disorders. The Divided Mind traces the history of psychosomatic medicine, including Freud's crucial role, and describes the psychology responsible for the broad range of psychosomatic illness. The failure of medicine's practitioners to recognize and appropriately treat mindbody disorders has produced public health and economic problems of major proportions in the United States. One of the most important aspects of psychosomatic phenomena is that knowledge and awareness of the process clearly have healing powers. Thousands of people have become pain-free simply by reading Dr. Sarno's previous books. How and why this happens is a fascinating story, and is revealed in The Divided Mind .
