Embodiment 1
[0028] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses a tool for preventing phase-to-phase short circuit for non-stop operation of distribution network, including insulating rod 4. The material of insulating rod 4 in this embodiment is Lingke rod, and its working voltage range is between 10- 35kv, which is sufficient for the voltage in the distribution network; the first area on the insulating rod 4 is connected to the first connecting mechanism 5, the second area on the insulating rod 4 is connected to the second connecting mechanism 6, and the second connecting mechanism 6 on the insulating rod 4 The three areas are connected with a third connecting mechanism 7, wherein the first connecting mechanism 5 is used to connect the first electric wire 1, the second connecting mechanism 6 is used to connect the second electric wire 2, and the third connecting mechanism 7 is used to connect the third electric wire 3 , wherein, t...
Embodiment 2
[0040] In a typical embodiment of the present invention, such as image 3 and Figure 4 As shown, this embodiment discloses a tool for preventing phase-to-phase short circuit for non-stop operation of distribution network. The difference between this embodiment and Embodiment 1 is that the first connecting mechanism 5 and the second Connecting mechanism 6 and the 3rd connecting mechanism 7 all comprise U-bolt 51, nut and stopper 55, and the two ends of U-bolt 51 are connected through stopper 55, and the two ends of U-bolt 51 all have threads, and U-bolt Both ends of the threaded connection nut. That is, the structures of the first connecting mechanism 5 , the second connecting mechanism 6 and the third connecting mechanism 7 are the same, all of which are combinations of U-shaped bolts 51 and nuts.
[0041] More specifically, the two ends of the U-bolt 51 are respectively threaded to the first nut 53 and the second nut 54 , and when the first nut 53 and the second nut 54 are...
Embodiment 3
[0044] In a typical embodiment of the present invention, such as image 3 and Figure 4 As shown, this embodiment discloses a phase-to-phase short-circuit prevention system for distribution network without power failure, including multiple devices as shown in Embodiment 1 or Embodiment 2, and multiple devices are arranged in the same line at intervals. The "interval arrangement" here means that multiple devices are arranged in the same line according to the set distance.
[0045] In this embodiment, the insulating rods use lighter materials, such as epoxy resin, with a density of 0.9-1.25g / cm 3 In between, using this material as an insulating rod can provide sufficient support strength while maintaining light weight.
[0046] In this embodiment, one or more of the devices in Embodiment 1 may be provided on the vertical arc between two line towers or between two line poles to form an overall system.
