Abstract
The utility model is a kind of adjustable metal-enclosed bus crane span structure, its structure comprises metal shell, bus, insulation column, stainless steel telescopic joint, fixing gold utensil, wherein, metal shell and stainless steel telescopic joint form the shell of bus bridge frame jointly, bus is fixed by being fixedly installed to insulation column on metal shell, and the busbar shiplap joint in Telescopic metal adjusting range is fixed overlap joint by fixing gold utensil, the suspender be fixed on the installed surface of wall top is used for lifting fixing metal housing.Advantage: because shell structure adopts stainless steel telescopic joint and busbar shiplap joint, stainless steel telescopic joint and busbar shiplap joint are again adopt fixing gold utensil to be fixed overlap joint, achieve the erecting bed telescopic adjustment of metal-enclosed bus crane span structure, and install convenient, labour intensity is little; Meanwhile, can avoiding equipment in running due to the change of temperature or stressedly occur dilatation, there is the problems such as overlap joint loosens in the vibration of equipment; Can be used for the flexible compensation of power distribution equipment because of needs such as installation site adjustment.
Description
Technical field
The utility model relates to a kind of for the adjustable metal-enclosed bus crane span structure in electrical power trans mission/distribution system, belong to high voltage electric equipment technical field.
Background technology
Known bus bridge frame be mainly used in generating equipment draw and transformer, transformer and high-low voltage power distribution device, delivery of electrical energy (as shown in Figure 1 and Figure 2) between high-low voltage power distribution device and high-low voltage power distribution device; Also for generator alternating current, DC excitation loop, the current delivery of transformer and distribution station (station) or other industrial civil equipment.
Existing metal-enclosed bus crane span structure is primarily of metal shell and bus composition, and frame mode adopts sectionally smooth join formula structure.Design and manufaction for metal-enclosed bus crane span structure all completes in device fabrication unit, installation and use is all carry out at user scene, but due to in-site installation environment, (switchgear house metope is uneven, uneven, installation foundation irregularity etc.) higher dependence, and measure and design the difference existed, result in bus bridge frame erecting bed often occurs long or too short, or metal shell can be in place, and bus cannot the problem such as normal mounting, directly have influence on normal mounting and the use of bus bridge frame, and then cause site installation test difficulty large, cost increases, simultaneously, because the overlap joint between metallic bus bar crane span structure and power distribution equipment is rigid overlap joint, so also can cause equipment in running due to the change of temperature or stressedly occur dilatation, the vibration of equipment occurs that overlap joint loosens, and also can have influence on normal, the safety of equipment for power transmission and distribution, stable operation when serious.
Summary of the invention
The utility model proposes a kind of adjustable metal-enclosed bus crane span structure, its object is intended to the above-mentioned defect overcome existing for prior art, this bus bridge frame can in the convenient installation of Commissioning field, metal shell adopts stainless steel telescopic joint and busbar shiplap joint that fixing gold utensil can be adopted to be fixed overlap joint, thus the erecting bed flexible (length) realizing metal-enclosed bus crane span structure regulates.
Technical solution of the present utility model: a kind of adjustable metal-enclosed bus crane span structure, it is characterized in that the shell being jointly made up of bus bridge frame metal shell and stainless steel telescopic joint, bus is located at by stainless steel telescopic joint, and the overlap joint of stainless steel telescopic joint and bus is fixed by metal shell.And the busbar shiplap joint in Telescopic metal adjusting range is fixed overlap joint by fixing gold utensil.
Advantage of the present utility model: because shell structure adopts stainless steel telescopic joint overlap joint, busbar shiplap joint is again adopt fixing gold utensil to be fixed overlap joint, thus the erecting bed achieving metal-enclosed bus crane span structure flexible (length) regulates, and install convenient, labour intensity is little.Meanwhile, can avoiding equipment in running due to the change of temperature or stressedly occur dilatation, there is the problems such as overlap joint loosens in the vibration of equipment; Even can be used for the flexible compensation of power distribution equipment because of needs such as installation site adjustment.
Accompanying drawing explanation
Accompanying drawing 1 is for bus bridge frame mounting structure schematic diagram between power distribution equipment.
Accompanying drawing 2 is for bus bridge frame mounting structure schematic diagram between transformer and power distribution equipment.
Accompanying drawing 3 is partial structurtes schematic diagrames of Fig. 1, Fig. 2 embodiment.
Accompanying drawing 4 is Fig. 3 internal structure schematic diagram.
Accompanying drawing 5 is bus bridge frame cross section structure schematic diagram.
In figure 1 is wall top installed surface, 2 are metal shells, 3 are suspenders, 4 are stainless steel telescopic joints, 5 are insulation columns, 6 are buses, 7 is fixing gold utensils.
Wall top installed surface, installation foundation face and switchgear house body of wall are the part of switchgear house.
Embodiment
As shown in Fig. 3, Fig. 4, Fig. 5, a kind of adjustable metal-enclosed bus crane span structure, its structure comprises metal shell 2, bus 6, insulation column 5, stainless steel telescopic joint 4, fixing gold utensil 7, wherein metal shell 2 and stainless steel telescopic joint 4 form the shell of bus bridge frame jointly, bus 6 is fixed by the insulation column 5 be fixedly installed on metal shell 2, and the overlap joint of bus 6 in stainless steel telescopic joint 4 scope is fixed overlap joint by fixing gold utensil 7, the suspender 3 be fixed on wall top installed surface 1 is used for lifting fixing metal housing 2.
Because shell structure adopts stainless steel telescopic joint and busbar shiplap joint to be adopt fixing gold utensil to be fixed overlap joint, thus the erecting bed flexible (length) achieving metal-enclosed bus crane span structure regulates, and install convenient, labour intensity is little.Meanwhile, can avoiding equipment in running due to the change of temperature or stressedly occur dilatation, there is the problems such as overlap joint loosens in the vibration of equipment; Even can be used for the flexible compensation of power distribution equipment because of needs such as installation site adjustment.And then ensure safe, stable, the reliability service of transmission & distribution equipment.
Construction period can be shortened, and it is little to install labour intensity; In addition product structure advantages of simple, consumptive material is few, cost is low.Meanwhile, the high security of product in operation and high reliability should also be possessed.
