AC/DC Common Bus Duct Protection for Separate Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AC/DC common busbars face challenges in separate checking and maintenance, leading to exposure and damage, affecting power transmission efficiency and increasing maintenance costs.
Innovation Solution
The AC/DC common busbar features a base plate with detachable bar bodies and limiting protection structures that allow separate checking and maintenance, providing overall and individual protection, while an inspection robot performs continuous performance detection using sensors and a controller for intelligent maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the busbar is connected to both AC bus and DC bus simultaneously, then power transmission capability is improved, but maintenance convenience deteriorates
Solution Approach 1:
The common busbar is divided into separate AC busbar and DC busbar components that can be independently accessed and maintained. The protective cover can be selectively opened to expose only the required busbar type, enabling separate checking and maintenance of AC and DC connections without affecting the other side.
2Ease of repair
If the busbar is connected with the AC bus or the DC bus individually, then maintenance convenience is improved, but protection capability deteriorates
Solution Approach 1:
The protective cover is designed to be dynamically adjustable, allowing it to be opened selectively to expose only the AC busbar or DC busbar that requires maintenance, while the other busbar remains protected. This dynamic protection approach prevents unnecessary exposure damage while maintaining ease of repair.
3Ease of operation
If the copper bar group is exposed outside, then accessibility for maintenance is improved, but reliability deteriorates
Solution Approach 1:
The protective cover is segmented into regions that can be independently opened, allowing maintenance personnel to access only the specific copper bar group that requires maintenance while other copper bar groups remain protected, thus maintaining reliability while improving accessibility.
4Object-affected harmful factors
If the limiting protection structure is permanently fixed, then protection capability is improved, but maintenance accessibility deteriorates
Solution Approach 1:
The limiting protection structure incorporates movable and fixed portions, where the movable protective cover can be temporarily removed or opened to provide maintenance accessibility, then restored to provide protection capability. This dynamic design resolves the contradiction between permanent protection and maintenance accessibility.

AI summary
An alternating current/direct current common bus duct, comprising: a bottom plate (1) parallelly provided with at least one pair of detachable duct bodies (2), a copper bar group (4) being connected to the same side of each pair of duct bodies (2), each copper bar group (4) comprising a plurality of copper bars arranged at intervals; and at least one pair of limiting protection structures (9) correspondingly mounted on each copper bar group (4), wherein each limiting protection structure (9) is used for separating from the corresponding copper bar group (4) when the copper bar group (4) is in a use state, and for inserting into a gap between adjacent copper bars in the corresponding copper bar group (4) when the copper bar group (4) is in a non-use state. The alternating current/direct current common bus duct can utilize a separation and assembly structure of the limiting protection structure (9) to implement separate checking and maintenance if the bus duct is connected to both an alternating current bus and a direct current bus, and implement the overall protection of a copper bar group and individual protection of copper bars if the bus duct is individually connected to the alternating current bus or the direct current bus to effectively avoid excessive exposure of the copper bar group in an unnecessary state, thus preventing a bus and a bus duct from being damaged, effectively improving the power transmission efficiency and effect, reducing maintenance costs, and prolonging the service life of a bus duct. The present invention also relates to a bus duct detection method and device.
