多年来,我国铁路研制出以安全型继电器为基础器材的电气集中设备,建立了符合我国具体情况的电气集中体系。目前我国电气集中车站由解放初期一二个,发展到1,100个,电动道岔占全国联锁道岔的50％,电气集中的迅速发展,为提高铁路运输效率,保证行车安全创造了条件。在电气集中设备中采用了大量的电气器件,为了保证这些器件经常处于良好的使用状态,几年来,围绕电气集中的测试及报警展开了群众性的技术革新运动,研制出简而易行的有实用价值的测
Over the years, China’s railway developed a safety-based relay-based equipment for electrical concentration, established in line with China’s specific circumstances of the electrical concentration system. At present, the centralized electric station in China has grown from one or two in the early days of liberation to 1,100. The electric turnout occupies 50% of the national interlocking turnout. The rapid development of electric concentration has created the conditions for improving railway transportation efficiency and ensuring traffic safety. A large number of electrical devices are used in the electrical concentration equipment. In order to ensure that these devices are often in good use condition, mass-based technological innovation campaigns have been carried out around the electric concentration test and alarm in recent years. Practical value of the test
