Embodiment Construction
[0023] The following describes in detail the internal power supply interlocking controller of a reactor protection system of the present invention in conjunction with the accompanying drawings and specific embodiments:
[0024] Such as figure 2 As shown, a reactor protection system internal power interlock controller, including power components, relay components and rectifier diodes. Among them, the power supply components include 24V DC regulated power supply and 12V DC regulated power supply, four for each type. The relay components include power failure monitoring relays and interlock relays, among which there are 4 power failure monitoring relays and 2 interlock relays. The number of rectifying diodes is four.
[0025] The ground terminals of the first 24V DC stabilized power supply and the second 24V DC stabilized power supply share the ground, and their 24V voltage output terminals are respectively connected to the negative terminal of the first rectifier diode and th...

The invention belongs to the technical field of reactor protection, specifically relates to an internal power supply interlocking controller of a reactor protection system, and aims to provide a device capable of solving the problem of equipment malfunction caused by power failure in the existing reactor protection system. The device includes a power supply assembly, a relay assembly and a rectifier diode; wherein, the power supply assembly includes a 24V DC regulated power supply and a 12V DC regulated power supply, four for each type; the relay assembly includes a power failure monitoring relay and an interlocking relay, wherein , 4 power failure monitoring relays, 2 interlock relays; the number of rectifier diodes is 4. The present invention uses a power supply assembly, a relay assembly and a rectifier diode to automatically cut off the working power supply of the output cabinet when the two logic cabinets in the reactor protection system lose power, preventing the failure of the two logic cabinets in the reactor protection system to cause the reactor protection system to malfunction. action.
Description
technical field [0001] The invention belongs to the technical field of reactor protection, and in particular relates to an internal power supply interlocking controller of a reactor protection system. Background technique [0002] The reactor protection system (referred to as RPR) includes emergency shutdown system, special safety system and ATWT system, which is composed of electrical components, mechanical components and circuits, and is used to generate protection signals. Its function is to prevent or mitigate damage to the core and coolant system components by shutting down and / or activating special safety facilities under abnormal or accidental conditions of the reactor, and to protect the integrity of the three major nuclear safety barriers Sex, avoid causing a large amount of radioactive substances to escape, protect the environment around the nuclear power plant from pollution and the safety of personnel. [0003] The logic processing part of a reactor protection s...
