Abstract
The utility model discloses a kind of transformer inner cable joint fixed support, comprise base, base is vertically provided with main support, the top of main support is provided with assistant support, assistant support is provided with U-shaped draw-in groove, and described base is connected with earth connection.The utility model can be good at sharing and reduces transformer and draw the cable active force that wiring bus-row and supporting insulator bear, and maintainer can be facilitated to carry out disconnectedly regarding it as again and the work of better services high-tension cable correlation test to cable simultaneously.Greatly improve operating efficiency, cable fault rate can be effectively reduced, extend the useful life of cable and insulator, for the safe and stable operation of transformer provides guarantee.
Description
Technical field
The utility model relates to hv cable termination stationary device, especially a kind of can secure support high pressure dry low pressure side connect the transformer inner cable joint fixed support of cable joint.
Background technology
At present, station-service high pressure dry transformer is three-phase combined transformer, and along with the increase of the capacity of manufacture, volume is also corresponding larger.Power station high pressure dry cable that low pressure side connects is generally station service bus provides main power supply, and running current is larger.Consider reduction impedance during design, low pressure winding adopts paired cable and tie, and cable is generally the very large band-armored of very sectional area, and the hardness of cable own is high, quality weight.Thus make transformer low voltage winding extraction wiring bus-row bear from the very large pulling force of cable joint, although there is the support of master row insulating, but External Force Acting may cause low pressure to draw wiring bus-row distortion for a long time, supporting insulator even may be caused to damage, finally may affect the safe and stable operation of transformer.Simultaneously when overhauling transformer, because inside transformer space is narrower and small, draw binding post distance ground and have certain altitude, operated by personnel is very difficult, when low voltage side cable is disconnected draw after, the easy landing of cable, brings certain difficulty to cable high voltage test, also electric cable accessories may be caused to scratch damage, affect cable useful life.When drawing cable again after maintenance completes simultaneously, lacking the cable of support, after untiing, resilience can occur, adding that weight own brings certain difficulty to drawing work again.
Summary of the invention
The purpose of this utility model is for above problem, a kind of transformer inner cable joint fixed support is provided, the potential safety hazard that high-tension transformer lead-out wire and high-tension cable junction exist can be solved, high-tension cable junction is effectively fixed, reduce cable fault.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of transformer inner cable joint fixed support, comprises base, base is vertically provided with main support, the top of main support is provided with assistant support, assistant support is provided with U-shaped draw-in groove, and described base is connected with earth connection.
The two ends of described U-shaped draw-in groove are fixedly connected with the two ends of assistant support by bolt; Cable is arranged between U-shaped draw-in groove and assistant support, plays laterally fixing effect.
Described assistant support and main support are mutually vertical.Main support is made for adopting channel-section steel, and assistant support is arranged on the side that channel-section steel deviates from groove.Cable main is fixed on the back side of channel-section steel, provides the support of vertical direction and fixes.
The top 10cm of described assistant support distance main support.Cable by vertical firm fixing while, a part of power is dispersed on assistant support, and the amount of exerting all one's strength obtains reasonable distribution, effectively alleviates the strength of supporting insulator.
Described base is connected with ground by expansion bolt, makes whole support be in ground state.
The utility model is owing to adopting said structure design, can be good at sharing and reduce transformer and draw the cable active force that wiring bus-row and supporting insulator bear, maintainer can be facilitated simultaneously to carry out disconnectedly regarding it as again and the work of better services high-tension cable correlation test to cable.Greatly improve operating efficiency, cable fault rate can be effectively reduced, extend the useful life of cable and insulator, for the safe and stable operation of transformer provides guarantee.
Accompanying drawing explanation
Fig. 1 is using state schematic diagram of the present utility model.
Embodiment
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of transformer inner cable joint fixed support, comprise base 1, base 1 is vertically provided with main support 2, the top of main support 2 is provided with assistant support 3, assistant support 3 is provided with U-shaped draw-in groove 4, and described base 1 is connected with earth connection 5.
Further, the two ends of described U-shaped draw-in groove 4 are fixedly connected with by the two ends of bolt with assistant support 3.Described U-shaped draw-in groove and main support can also coat corrosion resistant coating.
Further, described main support 2 adopts channel-section steel to make, and assistant support 3 is arranged on the side that channel-section steel deviates from groove.
Further, described assistant support 3 is mutually vertical with main support 2.
Further, described assistant support 3 is apart from the top 10cm of main support 2.
Further, described base 1 is connected with ground by expansion bolt.
During use, the cable of phase-splitting is fixed between assistant support 3 and U-shaped draw-in groove 4, attention can not make distortion of the cable, then cable and U-shaped draw-in groove are fixed on main support together, treat that the cable joint of phase-splitting is positioned at the top of main support, before the mounting, preprepared insulation rubber on the cable position pad of contact, meanwhile, the copper shield of cable and armouring should carry out ground connection, and base and main support are also fixed in bottom surface or transformer respectively by bolt or screw.By aforesaid operations, complete the fixing of cable; Can either be effectively fixing, facilitate again the operation in later stage to construct.
