Stepless adjusting type bus bar isolation device

Abstract

The invention discloses a stepless adjustment type bus bar isolation device. The two stand columns can be vertically arranged on the outer sides of the two bus barrels, the transverse supporting piece is located above the two bus barrels and can be used for being connected between the two stand columns, and the warning device is fixedly installed on the transverse supporting piece and located between the two bus barrels. The device has the advantages that assembly and disassembly are convenient and fast, the operation efficiency is greatly improved, crossing isolation can be carried out between two bus cylinders, during use, the intuition is good, the applicability is high, the requirements of work ticket safety measure arrangement specifications are met, in addition, the overall structural design is stable, and the cost is low. The maintenance personnel are not easy to move away or cross the barrier to a non-maintenance area, and the situation that the maintenance personnel are influenced by severe weather is avoided, so that the potential safety hazard is eliminated, and the use reliability is ensured.

Description

technical field [0001] The invention relates to a safety protection measure for busbar barrel equipment in a GIS substation, in particular to an infinitely adjustable busbar barrel isolating device. Background technique [0002] At present, part or all of the GIS substation adopts double-bus connection mode. Due to the influence of the position of the bus barrel of the GIS substation, the traditional hard fence cannot be directly crossed. Hard fences are enough, but this method does not meet the layout specifications of work ticket safety measures, and maintenance personnel can easily move away or cross the barrier to the non-maintenance area, which has certain potential safety hazards; A soft fence is used in the middle to isolate the maintenance interval from the operation interval. The disadvantage is that in the case of strong winds, the fence may be blown off or hung on the operating equipment, which also poses a safety hazard. When the net isolating the busbar barrel,...

Problems solved by technology

[0002] At present, part or all of the GIS substation adopts double-bus connection mode. Due to the influence of the position of the bus barrel of the GIS substation, the traditional hard fence cannot be directly crossed. Hard fences are enough, but this method does not meet the layout specifications of work ticket safety measures, and maintenance personnel can easily move away or cross the barrier to the non-maintenance area, which has certain potential safety hazards; A soft fence is used in the middle to isolate the maintenance interval from the operation interval. The disadvantage is that in the case of strong winds, the fence may be blown off or hung on the operating equipment, which also poses a safety hazard. When the net isolating the busbar barrel, because the seine itself is easy to be entangled, it takes a long time to sort out before installation, and it is not beautiful after installation, which is a waste of time and does not achieve a good isolation effect

[0003] It has been proved by practice that neither of the above two situations satisfies the safety measures set in the “State Grid Jiangsu Electric Power Co. Entrances and exits should be located near the road or in a place that is convenient for entry and exit"
