Embodiment approach
[0027] An irregular cavity is arranged inside the fixture 1 . exist figure 1 , figure 2 and Figure 5 In the first embodiment of the present invention shown, the area of the irregular cavity 21 is small;
[0028] exist image 3 , Figure 4 and Figure 6 In the second embodiment of the invention shown, the irregular cavity 22 has a large area.
[0029] The invention is suitable for a splint carrying rectangular conductors with a working current of 2000A to 6300A, and one to four pieces of rectangular conductors can be installed.
[0030] When passing through the metal enclosure of the switchgear, it must be made of insulating material. The hollow parts of the present invention ensure the insulation distance of the conductors, so that the conductors can operate normally when they are charged, and when multiple rectangular conductors pass through the hollow parts, the multi-piece rectangular conductors are supported, and the multi-piece rectangular conductors can be arr...

The invention discloses a supporting fixture of a rectangular conductor, which has good insulating performance and high intensity. The M-shaped supporting fixture aims at solving the problems that the volume of the groove type conductor in the present medium / high-voltage electric field is large, the requirement for the volume of a wall bushing is higher and the cost is high. Supporting ribs are arranged at the two sides of the supporting fixture. The supporting fixture is suitable for load-bearing a clamping plate of the rectangular conductor with the working current of 2,000 to 6,300A. One to four rectangular conductors can be installed, four rectangular conductors can be divided into two groups, each group comprises one to two rectangular conductors, two groups of grooves are symmetrically arranged, the conductors are separated by bulges between the grooves, and inclined planes which are arranged at the bottom parts of the grooves can support the conductors to some degree. The supporting fixture is made of nylon materials and is formed by a mould through pouring; the flexibility of the materials is good and the conductors cannot be damaged; the rectangular conductors with different specifications can be installed; the insulating performance is good, the intensity is high, and the practical application range is wide.
Description
technical field [0001] The invention is applied in the medium and high voltage electric field, and is specifically a rectangular conductor support fixture. Background technique [0002] The conductor is used to transmit electric energy, and its cross-sectional shape, size and quantity determine the amount of electric energy it can carry. For the transmission mode with a working current of 4000A or more at a voltage level of 15KV and below, when multiple rectangular conductors are used, when they pass through When steel sheet metal parts are used, non-conductive material products (commonly known as wall bushings) must be installed for insulation. It has two functions: 1) for insulation, and 2) for support of conductors. When the 4000A ~ 6300A working current is carried by a rectangular conductor, the shape and strength of the wall splint are particularly important. [0003] In the medium and high voltage electrical field, the existing wall-penetrating splints are all made of...
