Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nuclear reactors face challenges in maintaining cooling and electrical power during extreme emergency situations, such as natural disasters, where conventional power and cooling systems can be disabled, necessitating a reliable method to supply emergency power to switchgear buses.
Innovation Solution
A connection device comprising a mounting assembly, electrical transfer assembly, and base assemblies with stud members and load interconnect members is used to connect a portable generator to a switchgear bus, enabling the supply of emergency power by establishing an electrical pathway through interconnect assemblies and stud members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power systems are used in nuclear reactors, then normal electrical power supply is maintained, but the system becomes vulnerable to disablement during extreme emergency situations such as natural disasters
Solution Approach 1:
The electrical system is segmented into multiple independent power sources including conventional power systems and portable generator systems. Each segment can operate independently, so when the conventional system fails due to natural disasters, the portable generator segment can take over to maintain power supply to critical components like switchgear buses and cooling systems.
Solution Approach 2:
Portable generators and connection devices are pre-positioned and prepared in advance before emergencies occur. The system includes pre-installed mounting assemblies, electrical transfer assemblies, and connection devices that can be quickly deployed to establish power connections without requiring complex installation during emergency situations.
2Reliability
If portable generators are deployed for emergency power supply, then power can be maintained during emergencies, but the complexity of the electrical system increases
Solution Approach 1:
Connection devices serve as intermediaries between portable generators and the nuclear reactor's electrical system. These connection devices include standardized mounting assemblies, electrical transfer assemblies with interconnect members, and base assemblies with stud members that facilitate straightforward electrical connections, reducing the complexity burden of integrating temporary power sources.
Solution Approach 2:
The connection devices and mounting assemblies are designed with universal applicability to work with different portable generator types and configurations. The electrical transfer assembly can accommodate various interconnect members and the base assemblies with multiple stud members can serve different connection requirements, allowing a single standardized interface to handle multiple emergency power scenarios.
3Loss of time
If quick connection devices are used to connect portable generators to switchgear buses, then emergency power can be supplied rapidly, but the connection device structure becomes more complex
Solution Approach 1:
The connection device is segmented into distinct functional modules: mounting assemblies for secure installation, electrical transfer assemblies with separate interconnect members for each electrical connection, and base assemblies with multiple stud members. This modular segmentation allows each component to be independently positioned and connected, enabling rapid assembly without requiring complex integrated structures.
Solution Approach 2:
All connection components including mounting assemblies, electrical transfer assemblies, and base assemblies are pre-configured and prepared before emergency situations arise. The interconnect members and stud members are pre-positioned with appropriate orientations and spacing, so when deployment is required, the connection can be established quickly by simply connecting the electrical terminals without needing to configure the structural framework during the emergency response.

AI summary
A connection device is for an electrical system. The electrical system has a powering apparatus, an electrical switching apparatus, and a switchgear bus. The electrical switching apparatus is coupled to the powering apparatus. The connection device includes: a mounting assembly having a panel and a support wall opposite the panel; an electrical transfer assembly including: a number of interconnect assemblies each having a load interconnect member, the load interconnect member being coupled to the panel and electrically connected to the powering apparatus; and a number of base assemblies each including: a number of stud members each coupled to the support wall. At least one of the number of stud members is electrically connected to the load interconnect member and electrically connected to the switchgear bus.
