[0002] Nuclear power belongs to the category of clean energy. With the country's emphasis on environmental pollution, people began to pay more and more attention to the application of nuclear energy in the process of looking for alternative energy sources. The main application of nuclear energy is power generation. Nuclear energy, a clean energy, will be used in power generation Occupy a large market share, with the growing trend of localization, the existing relay has been difficult to meet the needs of nuclear power

[0003] The problems existing in the existing time relay are: the input voltage range of the existing time relay is too narrow, and when the voltage range is wide in the actual working condition, it has a great influence on the delay setting time; the power gain and loss of the existing time relay cannot be monitored, The working status is not clear, which is not conducive to the maintenance and inspection of nuclear power plant maintenance personnel; the existing time relay has no delay adjustable function, and it is difficult to adjust to the specification of a specific setting time under the actual working conditions on site; the output status of the existing time relay Single, unable to meet the requirements of multi-state output at the same time; the existing relay contact structure is not sealed, which cannot meet the requirements of field use. After the relay works for a period of time, dust and other redundant substances or harmful gases in the air will be buckled from its base and cover The contact point enters the interior of the relay, resulting in poor contact of the contacts and reducing the reliability of the relay; in addition, the existing relay does not have maloperation protection, and human errors will cause the knob of the potentiometer to rotate, resulting in timing changes
