Abstract
The utility model provides a small bus row at a transformer station protection screen cabinet top end. The small bus bar comprises terminal rows formed by vertically-arranged terminals, wherein a top end of each protection screen cabinet is respectively provided with one terminal row, the protection screen cabinets and the terminal rows of the protection screen cabinets are connected through single-stranded plastic wrapping hard copper wires of phi 1.28mm to phi 1.91mm, and the top end of each protection screen cabinet is respectively provided with a cover plate. The small bus row at the transformer station protection screen cabinet top end makes construction convenient, is convenient for compatibilization, has a flexible wiring mode, is safe, fast and convenient to realize wire disassembling, further improves insulation strength in an electrical loop, is convenient for operation after moving, greatly improves anti-interference capability integrally and reduces capital construction cost by about 90%.
Description
Technical field
The utility model relates to a kind of arrangement of little bus, and the little bus that more particularly relates to a kind of transforming plant protecting screen cabinet top is arranged.
Background technology
The modular design of China transformer station is opened and is come from four, the design of the former Soviet Union of the fifties, and up to the present, still also part adopts thinking in the former design, and along with present new equipment is constantly popularized, some operational mode is incompatibility new equipment and new job requirement.Specifically; the little bus installation arrangement design on the protection screen cabinet top of transformer station is that little bus is connected on the terminal board at present; when the little bus in former transforming plant protecting screen top adopts the two up and down staggered floor arrangement of the copper rod of exposed φ 6mm-φ 8mm or copper pipe; the little bus on screen top is when construction; the copper rod of φ 6mm-φ 8mm is big because of difficulty of construction; the bad processing of insulating; operation maintenance is extremely inconvenient; especially after operation puts into operation; when undergoing technological transformation; if fruit wiring on little bus just becomes very inconvenient.And; on the terminal board downwards the housing screw of protection screen cabinet lead all be horizontally disposed, and housing screw is again setting below little bus, is in operation when disassembling lead-in wire; all be charged copper rod around the lead-in wire, work is carried out in the danger that the operative employee will emit the person to get an electric shock.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model provides the little bus on a kind of transforming plant protecting screen cabinet top to arrange.
The utility model is achieved through the following technical solutions: the little bus on a kind of transforming plant protecting screen cabinet top is arranged; comprise the terminal board of being formed by the terminal of a plurality of vertical arrangements; the top of described each protection screen cabinet arranges a terminal board, and the sub-thread plastic foreskin hard copper wire by φ 1.28mm---φ 1.91mm between the terminal board of protection screen cabinet and protection screen cabinet is connected.
In the such scheme, in order to protect because of the device power supply (DPS) short circuit that the roof leaks and anomalies drops and causes, improve the electric insulation level of secondary device operation, the top of described each protection screen cabinet is provided with cover plate.
The beneficial effect that the little bus on the utility model transforming plant protecting screen cabinet top is arranged is:
1, little bus uses sub-thread plastic foreskin hard copper wire as lead, and the job placement of cloth winding displacement needs only common wiring worker 1 people and just can finish, and construction intensity reduces;
2, use the sub-thread plastic foreskin hard copper wire of φ 1.28mm--φ 1.91mm, material cost is low by 90% than the copper rod cost, remarkable in economical benefits.
3, use the sub-thread plastic foreskin hard copper wire of φ 1.28mm--φ 1.91mm, in servicely safeguard that dismounting connects become safety and easily of lead-in wire, when when 220kV and above transformer station use, rationally arrange even there is a large amount of little buses also can push up at protection screen in addition.
Description of drawings
Fig. 1 is that the little bus on former transforming plant protecting screen cabinet top adopts copper rod structure arranged schematic diagram;
Fig. 2 is the little bus structure arranged schematic diagram on the utility model transforming plant protecting screen cabinet top.
Among the figure: 1. protection screen cabinet, 2. terminal board, 3. time lead-in wire, 4. copper rod, 5. lead transboundary, 6. sub-thread plastic foreskin hard copper wire is 7. gone up housing screw, 8. housing screw, 9. cover plate.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the little bus arrangement that the utility model transforming plant protecting shields the cabinet top is further described:
Fig. 1 is that the little bus on former transforming plant protecting screen cabinet top adopts copper rod structure arranged schematic diagram; among the figure; the protection screen cabinet of transformer station all is arranged side by side; on the top of single protection screen cabinet 1 two terminal boards 2 are set vertically; what the little bus between the terminal board 2 was used is the copper rod 4 of φ 6mm-φ 8mm; by last housing screw 7 copper rod 4 is compressed; then be to connect with lead 5 transboundary between the terminal board 2 on adjacent two protection screen cabinets 1; and the following lead-in wire 3 that in protection screen cabinet 1, connects on the terminal board 2 be arranged on copper rod 4 below; and down the housing screw 8 of lead-in wire 3 all is again horizontally disposed, copper rod 4 arrange again than comparatively dense.Like this, in the construction of protection screen cabinet 1 lead, degree of tightness housing screw 8 was very inconvenient when the maintainer operated, and the personnel that very easily cause get an electric shock or the device power supply (DPS) short circuit, connected also inconvenience of line in addition in the screen cabinet.
Fig. 2 is the little bus structure arranged schematic diagram on the utility model transforming plant protecting screen cabinet top.Among the figure; the top of protection screen cabinet 1 only arranges a terminal board 2; sub-thread plastic foreskin hard copper wire 6 by φ 1.28mm---φ 1.91mm between the terminal board 2 on adjacent two protection screen cabinets 1 connects; like this; it is just very convenient when the maintainer operates; personnel get an electric shock and the power supply short circuit situation greatly reduces, and in installation, working strength also greatly reduces in addition.Simultaneously, in order to protect because of the device power supply (DPS) short circuit that the roof leaks and anomalies drops and causes, improve the electric insulation level of secondary device operation, the top of each protection screen cabinet 1 is provided with cover plate 9, plays the effect of proofing dust and protecting.
By facts have proved, use the copper rod 4 of the sub-thread plastic foreskin hard copper wire 6 replacement φ 6mm-φ 8mm of φ 1.28mm---φ 1.91mm, satisfy substation secondary fully and combine specification requirement from equipment, and make easy construction, little bus increase-volume is convenient, the mode of connection is flexible, little bus is disassembled line safety, quick, convenient, also improves dielectric strength in the electric loop simultaneously, has made things convenient for the O﹠M after putting into operation, install whole antijamming capability and greatly improve, the capital construction cost descends about 90%.
