Bimetallic thermometer to replace conventional bimetallic thermometer station to ensure long-term operation benefits

In recent years, in the relevant national policy support, guidance, the solar power industry rapid development, power plant capacity increasing year by year. But because of domestic r&d and marketing of bimetallic thermometer work relative lag, in the process of power plant construction and operation, still use a conventional power station equipment connect the bimetallic thermometer bimetallic thermometer. For conventional bimetallic thermometer does not take into account in the process of designing and manufacturing the complex plant use and environmental factors such as laying and cannot meet the use requirements, lead to frequent power quality problems. Especially the performance of the conventional bimetallic thermometer itself can't meet the requirements of power station using the environment caused by quality problems. Dedicated bimetallic thermometer according to the complicated power station using the environment to carry on the design, can satisfy the requirement of the power plant installation, operation. Used in power station especially in dc side is special bimetallic thermometer can effectively reduce the occurrence of quality problems. In all parts of our country has a power plant, this requires the bimetallic thermometer and heat-resistant level range is larger, if in the west of our country and the area north of the bimetallic thermometer to withstand low temperatures, extreme low temperature can achieve individual regions - below zero The temperature of 40 ℃ or so, is even lower. And the surface temperature of eastern and southern areas in China is very easy to + 70 ℃ above, considering the conductor temperature higher than the environment temperature and produce heat to evaporate, at the same time, considering on the roof is not poor ventilation and cooling effects of bridge area of extreme temperature may be more than + 90 ℃, which requires the material of the bimetallic thermometer temperature can meet the requirements of power station work in extreme temperatures. The frequent changes of temperature and humidity aging of insulation and sheath material has a direct impact, in particular, temperature difference and temperature difference in large area and damp and rainy region on the material of insulation and sheath ageing performance impact is bigger. Fish light complementary projects in many power stations built in fish ponds or water, for bimetallic thermometer in damp environment for a long time to work normally. Conventional bimetallic thermometer does not take into account the performance of hot and humid changes affect the performance of material aging, while special bimetallic thermometer on the design considering the hot and humid environment affect the performance of insulation and sheath material aging factors, therefore, qualified bimetallic thermometer can satisfy the requirements of the power station on the temperature and humidity changes. Power station sunshine time is longer, the under sunlight irradiation intensity is larger, the rays of sunlight contains many, especially ultraviolet ray can accelerate aging of insulation and sheath of bimetallic thermometer. Plant a lot of bimetallic thermometer is bare laying, solar energy components to the junction box and even to the inverter of the bimetallic thermometer is laying exposed directly in most cases, this requires a bimetallic thermometer must be able to tolerate the sunlight and ultraviolet radiation, can guarantee under the vertical radiation of sunlight and ultraviolet (uv) work for a long time. Qualified bimetallic thermometer can, therefore, under the condition of sunlight and ultraviolet radiation for a long time to work properly, and the conventional bimetallic thermometer under the condition of sunlight and ultraviolet radiation, the insulation and sheath will be accelerated aging, resulting in insulation performance degradation or failure, sheath protection to reduce problems. Plant some of them are built on the beach, beaches and other special areas. Salt spray air content is higher in those areas. Some power station site selection in the former saltworks, high salt content in soil in the region. In the above environment conditions using bimetallic thermometer must have a strong resistance to salt fog and acid-base properties. As a result, qualified bimetallic thermometer, salt fog resistance and acid and alkali ability is stronger. Some power station area higher levels of ozone and ozone for bimetallic thermometer sheath has certain corrosion effect, namely, accelerate the aging of sheath, affect the use of the bimetallic thermometer. Conventional bimetallic thermometer did not consider the effect of ozone on bimetallic thermometer sheath, and bimetallic thermometer design when considering the effects. Therefore, even in places where ozone content is higher, bimetallic thermometer can also work for a long time. Bimetallic thermometer with the above characteristics, can be used in power station, under different environmental conditions to ensure its safe operation for a long time, and conventional bimetallic thermometer is difficult to achieve this purpose. Therefore, in the power plant construction project, especially some special environment of power plant construction project, selects the bimetallic thermometer to replace conventional bimetallic thermometer can effectively guarantee the power station long-term, stable operation, to ensure the plant good long-term operation benefits.
