Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: 1. weld cabinet, 2. high strength insulator, 3. stop backing plate, 4. be flexible coupling, 5. vertical channel-shaped bus, 6. aluminium alloy anchor clamps, 7. blower fan, 8. branch's busbar, 9. isolating switch 10. is flexible coupling, 11. current transformer, 12. the stainless steel mounting panel, 13. horizontal busbar channels, 14. motor-operating mechanisms.
Specific embodiments
As shown in Figure 1, cabinet 1 adopts the 63# channel-section steel to be welded, and cabinet 1 has very high bulk strength.The every isolating switch 9 that by 4 TMY120X12 branch rows 8 current delivery is arrived 6300A mutually of main busbar.Again by be flexible coupling 10 with current delivery to horizontal busbar channel 13.Be flexible coupling and 10 pass current transformer 11 simultaneously, current measurement is carried out in the loop.The mounting panel 12 that current transformer 11 adopts the 1Cr18Ni9Ti corrosion resistant plate to make is fixing, the eddy-current heating phenomenon of avoiding big electric current to produce.Laterally busbar channel 13 4 is communicated with vertical channel-shaped bus 5 by being flexible coupling, and electric current is reached cabinet push up, and exports outside cabinet again.Busbar channel 5,13 is 150 * 65 flute profile copper busbars, adopts aluminium alloy anchor clamps 6 fixing.Aluminium alloy anchor clamps 6 are installed on high strength organic insulation 2 that bending strength reaches 15kN.Vertical channel-shaped bus 5 bottoms also fix with stop backing plate 3.
Isolating switch 9 adopts motor-operating mechanism 14 to carry out the branch closing operation, and the course of work fast, reliably overcomes the dependent manual operation high-current switch, the difficult problem that deciliter operating physical force is excessive.
Adopt busbar channel that higher ampacity can be arranged, satisfy the requirement of 6300A rated current.Busbar channel has high bending strength, satisfies the electrodynamic dynamic and thermal stability requirement of 63kA/4S short circuit current.In addition, busbar channel takes up room little, can guarantee the electrical distance requirement of 10kV switchgear.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
