Abstract
The utility model discloses a dysmorphism bus -bar expansion joint, including arc connecting piece and the copper mounting no. 1 and copper mounting no. 2 of setting at arc connecting piece both ends, mounting no. 1 is square, mounting policy of "literature and art should serve both people and socialism" parallelogram. This dysmorphism bus -bar expansion joint simple structure, reasonable in design, convenient to use, it saves labour to save time, can effectively reduce the stress that cable head and generating line overlap joint received to guarantee the generating line safe operation, improved the efficiency of generating line processing, reduced the cost of labor.
Description
Technical field
The utility model relates to the connection gold utensil in electric power system, specifically a kind of special-shaped bus expansion joint.
Background technology
Ring main unit is the electric equipment that high voltage switchgear is contained in assembled compartment ring network power supplying units in metal cabinet, has the advantages such as structure is simple, volume is little, price is low, power supply safety.In the power distribution station being widely used in the load centers such as Urban Residential District, skyscraper, large public building, factory and enterprise and box-type substation.The outlet of ring main unit is generally based on power cable, due to the spatial limitation of ring main unit, the restriction of manufacturing cable head is subject to during cable bond, existing expansion joint is the mode that straight line connects substantially, lap joint stress is larger, and joint bad connection will make joint temperature rise too high, directly affect the safety of cable, reliability service.
Utility model content
For solving the problems of the technologies described above, the special-shaped bus expansion joint that the utility model provides a kind of structure simple, easy to use.
The technical solution adopted in the utility model is: a kind of special-shaped bus expansion joint, and comprise arc connector and the copper fixture one and the copper fixture two that are arranged on arc connector two ends, described fixture one is square, and fixture two is parallelogram.
Preferably, described fixture one, the edge lengths that fixture two contacts with arc connector is identical.
The utility model has the advantages that: structure is simple, reasonable in design, easy to use, time and labour saving.Cable end in ring main unit is connected by special-shaped bus expansion joint with bus, effectively can reduces the stress that cable end and busbar shiplap joint are subject to, thus ensure that bus safe operation, improve the efficiency of bus processing, reduce cost of labor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is mounting structure schematic diagram of the present utility model;
In figure, 1. fixture one, 2. fixture two, 3. arc connector, 4. bus, 5. cable end, 6. cable tri-finger stall.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described, but protection range of the present utility model is not limited thereto.
As shown in Figure 1, a kind of special-shaped bus expansion joint, comprise arc connector and the copper fixture 1 and the copper fixture 22 that are arranged on arc connector 3 two ends, fixture 1 is square, and fixture 22 is parallelogram.The length of side of fixture 1, wide and arc connector 3 length of straight flange of fixture 22 is identical.
The cable be mainly used in ring main unit is connected with bus, as shown in Figure 2, during use, is fixed with special-shaped bus expansion joint below bus 4, and cable end 5 is gone between and to be connected with bus 4 by special-shaped bus expansion joint.The square copper fixture 1 of special-shaped bus expansion joint is connected with bus 4, and the minor face of parallelogram copper fixture 22 is connected with cable end 5.
It is simple, easy to use that the utility model has structure, the advantages such as time and labour saving, this special-shaped bus expansion joint changes the mode that original expansion joint only has straight line to connect, take one end square, opposite side is the structure of parallelogram, thus eliminating the stress of bus and cable joint, the cable end after installation is reached, and horizontal flat heavily fortified point is straight, neat appearance.
Claims (2)
1. a special-shaped bus expansion joint, is characterized in that, comprise arc connector and the copper fixture one and the copper fixture two that are arranged on arc connector two ends, described fixture one is square, and fixture two is parallelogram.
2. a kind of special-shaped bus expansion joint according to claim 1, is characterized in that, described fixture one, and the edge lengths that fixture two contacts with arc connector is identical.
