The semiconductor research institute of Kim Chaek University of Technology tries to realize domestic production of electronic parts.
“The Eighth Congress of the Workers’ Party of Korea set forth as an important task the domestic production of electronic components and various automatic devices. Our institute is concentrating efforts on achieving this goal,” said Pak Yong Thaek, director of the institute.
With the semiconductor material lab and electronic product lab as the centre, the institute has developed an exclusive sensor, power chip, control rectifier, power semiconductors for various purposes, digital temperature relay, digital heat regulator, water-gauge and flow-meter relying on domestic materials and new manufacturing methods.
Such successes led to revitalization of production in different sectors of the national economy, including the establishment of an integrated electricity production and management system at Orangchon Power Station Unit 3 which has recently been inaugurated.
The temperature measuring device for protecting generators made by the research institute is contributing to the normalization of electricity production at hydroelectric power stations.
“It arises as an important problem to reliably ensure the safety of generator operation in stabilizing and steadily increasing electricity production at power stations,” said Pak Son Guk, head of the semiconductor material lab.
According to him, hydropower stations used to have many troubles in production as the heat from rotation and friction from some parts like coiling of generators often caused breakdowns.
The institute designed the structure of a temperature sensor for generator protection and confirmed the characteristic indexes and made a perfect temperature display unit.
As a result, it became possible to measure and monitor the temperature of generators in real time, improving the reliability of the operation and increasing the electricity output.
Besides, the institute has brought out such high-tech electronic devices as 300A solid-state relay, one-channel and multichannel temperature display unit, 200A output rectifier, positioning chip, resistance pressure sensor and semiconductor pressure transmitter.
