Programmable 07KT93 module card power drive card mechanical protection device

Description

In order to ensure the stable operation of the photo thermal power station, ABB has provided 07KT93 complete medium and low voltage product solutions for the project, including VD4 vacuum circuit breaker, Emax2 air circuit breaker, Tmax molded case circuit breaker, AX contactor, relay, etc., which are used in the power distribution system of the photo thermal power station. Among them, VD4 vacuum circuit breaker, 07KT93, a star electric product of ABB, is mainly used for the control and protection of lines and loads. Its operating life can reach 40000 times, and it has accumulated more than 1 million safe operating experiences worldwide.
We are very pleased that ABB’s electrical products were applied to the first 100MW solar thermal project in China, which is another milestone of our business in China and also a new starting point. As a global technology leader, ABB is committed to developing and providing one-stop solutions to promote the development of emerging energy. 07KT93 will continue to contribute to the sustainable development of social economy and the building of a beautiful China in the future.

Solar thermal power generation is an important direction of new energy utilization. Photothermal power generation refers to gathering solar energy to provide steam through heat exchanger, and then driving steam turbine to generate electricity. It is suitable for centralized, large-scale and general areas, and can supply power for the whole region, even the whole country.
The photothermal power generation technology used in the 100MW tower type molten salt photothermal power station project is different from the conventional photovoltaic power generation. It uses molten salt or oil and other media to absorb the heat energy in the sunlight, and uses steam turbines to convert it into electric energy. Its essence is thermal power generation, and the heat comes from the heat collection system, which provides the feasibility for large-scale heat storage. Therefore, the solar thermal power generation is different from other forms of power generation with a heat storage system. Compared with other renewable energy sources, solar thermal has the greatest advantage, and its controllability is far higher than that of wind power and photovoltaic. For the power system, the grid is obviously more willing to accept relatively stable solar thermal power generation, and the development prospect is optimistic.
ABB can provide electrical products, systems and solutions covering the entire industrial chain for the solar thermal and photovoltaic industries, and provide professional support for grid connected and off grid solar power applications from the power generation end to the power consumption end. At the end of 2017, ABB also set up a new energy technology center in Shenzhen to support the development of China’s solar energy industry and clean energy by further enhancing its local R&D strength.
