Abstract

The invention relates to a special logic control device with a nuclear power set driving stage, which is characterized in that the invention comprises a logic functional module MU, a switch controller VDU, an automatic signal input port A5, a protection signal input port A6, a permitting signal input port A7, an equipment running state signal input port A8, a logic control signal output port OU1 and an equipment running state signal output port OU2, wherein, the switch controller VDU comprises a switch button and a control button. One group of signal input ends of the logic functional module MU are communicated with output ends of the switch button and the control button of the switch controller VDU. One group of signal input ends of the logic functional module MU are communicated with the signal port, and the signal output end is communicated with the logic control signal output port OU1. The equipment running state signal input port A8 is connected with the state testing end of controlled equipment, and the state signal output end of the logic functional module MU is communicated with the equipment running state signal output port OU2. The invention has the effects of clear interface, simple programmed work, easy modification and expansion and small influence among each other. The invention is widely suitable for the automatic logic control of a rear state driving mechanism of a nuclear power station with a stage of 1000mw.

Description

technical field [0001] The invention relates to a special logic control device for the driving stage of a nuclear power unit, which is suitable for the automatic logic control of the rear-stage driving mechanism of a 1000MW nuclear power plant. It belongs to the technical field of nuclear power plant electrical equipment. Background technique [0002] At present, domestic 1000MW nuclear power units are generally imported from abroad, and their logic control circuits are designed by foreign companies. The automatic logic control device of the circuit is composed of logic elements such as AND gate, OR gate, NOT gate, and memory to realize various logic control functions. However, for the design of the logical control part of the pump / fan, electric valve, pneumatic valve and other post-level drive equipment, only some basic logic elements are set in the overall logic control circuit. These basic logic units adopt decentralized non-standardized The design is not targeted, and ...
