Reactor Iron Core Coil Protection Against Foreign Matter Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In reactors with iron core coils, the projection portions of the coils can become damaged due to interference with foreign matter when passing through a pedestal or end plate.
Innovation Solution
A reactor design featuring a core body with an outer peripheral iron core and at least three iron cores, where gaps are formed between the iron cores for magnetic coupling, and a protection part is included to safeguard the projecting coil portions from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coils are arranged to project from the end surface of the core body for electrical connection, then the electrical connectivity is improved, but the projection portions become vulnerable to damage from foreign matter interference
Solution Approach 1:
A protection part is introduced as an intermediary component between the external environment and the coil projection portions. This protection part covers the vulnerable coil portions while allowing electrical connection, thus mediating between the need for electrical connectivity and the need for protection against foreign matter damage.
Solution Approach 2:
The protection part is designed to be installed beforehand to cover and protect the coil projection portions before they can be damaged by foreign matter. This preventive measure cushions the vulnerable parts from potential harm during operation and maintenance.
2Reliability
If the protection part is added to cover the coil projection portions, then the coil protection is improved, but the device complexity increases
Solution Approach 1:
The reactor is divided into distinct functional segments: the core body containing the coils, and the separate protection part that covers the projection portions. This segmentation allows the protection function to be added independently without redesigning the entire reactor structure, thus minimizing the increase in overall device complexity.
Solution Approach 2:
The protection part is designed to serve multiple functions: it protects the coil projection portions from foreign matter damage, provides structural support, and maintains the magnetic circuit integrity. By combining multiple functions into a single component, the design avoids adding unnecessary complexity while achieving comprehensive protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The protection part effectively prevents damage to the coils by covering and securing the projection portions, ensuring the coils remain intact and functional.
Implementation Method 1
gaps, which can be magnetically coupled, are formed between one of the at least three iron cores and another iron core adjacent thereto

AI summary
A core body of a reactor include an outer peripheral iron core, at least three iron cores arranged in contact with or coupled to an inner surface of the outer peripheral iron core, and at least three coils wound onto the at least three iron cores. Gaps, which can be magnetically coupled, are formed between the at least three iron cores. The reactor further includes a protection part which at least partially protects projection portions of the at least three coils which project from at least one end surface of the core body.
