Abstract
The utility model discloses a conductive strips and use conducting rod mechanism, isolator of these conductive strips. The substrate that is in the indent side in each layer substrate of the area of the conductive strips body is thicker than the substrate that is in the evagination side. Like this under the circumstances that the gross thickness of the area body remained unchanged, compare the substrate of uniform thickness among the prior art, the utility model discloses the reduction that total number of piles of substrate can be corresponding in the area body of well conductive strips, just also make the quantity of taking the heat source in the body reduce, corresponding calorific capacity that has reduced the whole area body, the radiating effect has been improved, the indent side of each layer substrate is in because of the substrate of thickened simultaneously, these indent pendant group pieces are smaller evagination pendant group piece is compared to the harmomegathus range of conducting rod swing in -process, though that is to say that the thickness of partial substrate has been increaseed, but the substrate of these thickenings can not just originally cause too big influence to the conducting rod passively, so swing that the conducting rod still can be normal.
Description
Technical field
The utility model relates to a kind of conductive strips and uses the conducting rod mechanism of these conductive strips, isolating switch.
Background technology
At present, State Grid Corporation of China proposes in " 12 " planning, China will build " three vertical three is horizontal " the ultra high voltage bulk transmission grid and 13 DC transmission engineering that connect large-scale Energy Base and main loads center from now on, form the energy source configuration general layout of extensive " transferring electricity from the west to the east ", " NORTEL south is sent ".By extra-high voltage direct-current Asynchronous Interconnection, the requirement of long distance, Large Copacity power transmission can be met, do not need along the line to provide power supply to support.Networked by ultra high voltage, strengthen network power exchange capacity, energy resources configuration mode can be optimized in a wider context.For better carrying out energy resources configuration, for direct current transportation, improving transmission capacity is further both economical way.During the design of underway sexupara line direct-current isolating switch capacity boost, the too high phenomenon of temperature rise of isolated switch main current-carrying part conductive strips is a bottleneck problem always, this seriously constrains the capacity boost design of product, therefore must redesign it, to meet the requirement that product capacity promotes.
Chinese patent literature CN102069275B(publication date is on May 25th, 2011) disclose one " welding procedure that isolating switch conductive arm is flexible coupling ", the conducting rod mechanism of isolating switch comprises the junction block be electrically connected successively, conductive strips and conducting rod, wherein conductive strips adopt the laminate aluminium foil of multi-disc uniform thickness to form, the two ends of conductive strips are inserted in the slot on junction block and conducting rod respectively, and the hole wall of corresponding jack or hole will be welded on after the end part aligning of conductive strips along upper, so in use, under the prerequisite of conductive strips conductive communication conducting rod and junction block, utilize the characteristic of aluminium foil softness, conducting rod can not be interfered relative to the swing of junction block.But along with the capacity boost of isolating switch; the thickness of conductive strips also needs to increase thereupon; now in conductive strips, the number of plies of aluminium foil also will be added thereupon; and with regard to individual layer aluminium foil; by less thickness effect; the resistance of individual layer aluminium foil is larger; this makes the gross calorific power of each layer aluminium foil in whole conductive strips increase thereupon; and gap between each layer aluminium foil is very little; so usually there will be through-flow poor performance, defect that caloric value is large in the conducting rod mechanism of isolating switch, increase the consumption of electric energy between conducting rod and junction block.And if conductive strips are replaced to one piece of all-in-one-piece belt body, the rigidity by belt body self limits, and conduction is taken back and hindered the wobbling action of conducting rod, to make the swing resistance of conducting rod excessive.
Utility model content
The purpose of this utility model is to provide a kind of when not affecting the good conductive strips that to dispel the heat conducting rod normally swings, and the utility model additionally provides and a kind ofly uses the conducting rod mechanism of these conductive strips and use the isolating switch of this conducting rod mechanism simultaneously.
In order to realize above object, in the utility model, the technical scheme of conductive strips is as follows:
Conductive strips, comprise the belt body that multi layer substrate is laminated, the both sides zone face of belt body is respectively for the concave side zone face of indent in conducting rod swing process and the convex side zone face for evagination in conducting rod swing process, and the substrate being in concave side in each layer substrate of belt body is thicker than the substrate being in convex side.
Define that each substrate being in the uniform thickness of concave side in each layer substrate is inner-layer substrate, to be in each substrate of the uniform thickness of convex side be outer substrate, the number of plies of inner-layer substrate is less than the number of plies of outer substrate.
Also have the middle level substrate be between inner-layer substrate and outer substrate in each layer substrate, the thickness of middle level substrate is greater than the thickness of outer substrate, is less than the thickness of inner-layer substrate, and the number of plies of middle level substrate is less than the number of plies of outer substrate.
The thickness of belt body is 100mm, and the thickness of inner-layer substrate is 0.3mm and has 10 layers, and the thickness of middle level substrate is 0.2mm and has 10 layers, and the thickness of outer substrate is 0.1mm and has 50 layers.
The two ends of belt body are provided with wards off tin layers.

Fig. 2 is the substrate thickness ratio schematic diagram of conductive strips when employing 15 layers of substrate in Fig. 1.
Embodiment
The embodiment of isolating switch in the utility model: as depicted in figs. 1 and 2, this isolating switch is a kind of neutral bus isolating switch for capacity boost, the agent structure of isolating switch is identical with existing common isolating switch, main improvement is the conductive strips in conducting rod mechanism between conducting rod and junction block, these conductive strips can be applicable in high voltage switchgear, High-Voltage Electrical Appliances manufacture field, on the neutral bus direct-current isolating switch of DC converter station, be mainly used in isolated switch main current-carrying part, connect external cabling and leading electric fracture.
The tin layers 5 of warding off that conductive strips are arranged by belt body 1 and two ends thereof forms, as shown in Figure 1, the downside of belt body 1 is the concave side caved inward all the time in conducting rod swing process, upside is the convex side of outwardly convex all the time in conducting rod swing process, and belt body 1 is by the outer substrate 4 stacking gradually layout from top to bottom, middle level substrate 3 and inner-layer substrate 2 form, the gross thickness of belt body 1 is 100mm, its ectomesoderm substrate 4 has 50 layers, and all adopt 0.1mm thick × the long copper strips of 150mm, middle level substrate 3 has 10 layers, and all adopt 0.2mm thick × the long copper strips of 150mm, inner-layer substrate 2 is also 10 layers, and all adopt 0.3mm thick × the long copper strips of 150mm.Ward off tin layers 5 end of mutually concordant each substrate is coated togather, so that install.
