Gansu GLB-2 microcomputer integrated protection, over-current, over-voltage, Speed ??(high-cycle) ..

Gansu GLB-2 computer integrated protection device manufacturers / Speed ??(high-cycle) protection relay dilapidated small hydropower generators, National Xu Zhen microcomputer integrated protection device to solve the problem of a lot of small hydropower stations, the factory of the unit are the 1960s, 70 years old unit, the more worn these protective relays and relay protection overvoltage value over the current value of the workers are free to modify the plant operator can easily lead to confusion protection value, malfunctions. Because geographically dispersed, competing Internet, mutual lift Internet voltage, causing the grid voltage line is too high, causing a serious impact on the annex residential users, and even damage to electrical equipment. National Xu Zhen produced GLB-2 microcomputer integrated protection, over-current, over-voltage, Speed ??(high-cycle), short circuit protection, simple operation, good reliability, with a digital display of voltage and current values ??and fault indicator, replacing the traditional multiple relay protection mode. GLB-2 computer integrated protection device is applicable to small and medium sized power plants and the transformation of the old power station protection, and can greatly improve the reliability of power plant turbines protection and security, but also has positive significance for improving the level of plant automation.
