Alternating current and direct current shared bus duct, bus duct detection method and detection system

Abstract

The invention provides an alternating current and direct current shared bus duct, a bus duct detection method and a bus duct detection system. The alternating current and direct current shared bus duct comprises a bottom plate which is provided with at least one pair of detachable groove bodies in parallel, the same side of each pair of groove bodies is connected with a copper bar group, and each copper bar group comprises a plurality of copper bars which are arranged at intervals; the at least one pair of limiting protection structures are correspondingly mounted on the copper bar groups; wherein the limiting protection structure is used for being separated from the corresponding copper bar group when the corresponding copper bar group is in a use state, and is used for being inserted into a gap between adjacent copper bars in the copper bar group when the corresponding copper bar group is in a non-use state. According to the alternating-current and direct-current shared bus duct, separation and assembly structures of the limiting protection structures can be utilized, so that separate maintenance can be performed under the condition that the bus duct is simultaneously connected with the alternating-current bus and the direct-current bus, and overall protection of the copper bar group and independent protection of each copper bar are realized under the condition that the alternating-current bus or the direct-current bus is independently connected.

Description

technical field [0001] The invention relates to the technical field of electric power transmission equipment, in particular to an AC and DC shared busbar, a busbar detection method and a detection system. Background technique [0002] The busway is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute high power to each element of the dispersion system. In indoor low-voltage power transmission trunk projects, bus ducts have increasingly replaced wires and cables. In the process of use, the busway has both the needs of connecting the AC bus and the need of connecting the DC bus. Therefore, for practical use, it is usually necessary to use a common busway to connect the AC bus and the DC bus at the same time. Although the existing common busway can be connected to the AC bus on one side and the DC bus on the other side, it is inconvenient to carry out separate maintenance in the event of a fault or in the routine maintenance proces...

Problems solved by technology

[0003] The present invention provides an AC-DC shared bus duct, which is used to solve the problem that the bus duct in the prior art is not convenient for separate maintenance when the AC bus and the DC bus are connected at the same time, and when the AC bus or the DC bus is connected separately , will cause other positions of the shared bus duct to be exposed, which will cause the bus duct to be easily damaged and affect the power transmission effect and efficiency
