Difficult to meet the requirements. In order to ensure a safe charging distance, when the equipment terminal board is connected to the wire, it is necessary to lead the terminal board out of the voltage equalizing ring and then connect to the wire to ensure a safe charging distance. In order to ensure a safe charging distance, it is necessary to add an aluminum plate to the primary terminal board to lead it out of the grading ring and connect it to the wire through the equipment clamp. This not only increases the difficulty of construction but also increases the construction investment.

detailed description

The following descriptions are preferred implementation examples of the present utility model, and therefore do not limit the protection scope of the present utility model.

Referring to Figure 1, the overall structure of HGIS equipment and wire connection will be introduced first. As shown in Figure 1, the top of the HGIS equipment 101 is a voltage equalizing ring 103, the terminal board 104 is located in the voltage equalizing ring 103, and the wire 102 is located outside the voltage equalizing ring 103 to meet the safety clearance requirement, therefore, as shown in Figure 1 As shown, the wires 102 are externally connected to the terminal block 104 by some auxiliary equipment. As mentioned in the background, the auxiliary equipment can be an aluminum plate connected to the terminal board 104 , which is equivalent to leading the terminal board 104 out of the voltage equalizing ring and then connecting it to the wire 102 .

Referring to Fig. 2 and Fig. 3 below, introduce the size of connecting terminal board 104 and voltage equalizing ring 103, as shown in Fig. Obviously, the terminal board 104 will be located in the voltage equalizing ring 103 and will not be higher than the voltage equalizing ring 103 .

Referring to Fig. 4 below, introduce the new equipment clamp that the utility model introduces. Figure 4 is a simplified schematic diagram of a two-conductor device clamp. As shown in FIG. 4 , the double-conductor equipment clamp includes a conductor connecting portion 201 connected to the conductor and a terminal board connecting portion 202 connected to the terminal board 104 . As shown in FIG. 4 , the terminal board connection portion 202 and the wire connection portion 201 are separated by a dotted line for example. Wherein, the lower end of the terminal board connecting portion 202 is connected to the terminal board 104, and the structure of the lower end is the same as that of the terminal board 104, and both include the same position and number of through holes to be fixed together by the fixing device. The lower end structure shown in FIG. 4 is the same as the lower end structure of the terminal board 104 shown in FIG. 2 , and both include four through holes with the same position and size, which can be fixed together by screws and bolts. The width a of the terminal board connecting portion 202 is the same as the width of the terminal board 104 , and the height h of the terminal board connecting portion 202 is 270 mm in one embodiment, which is 240 mm higher than the height of the equalizing ring 103 .

The partially enlarged diagram given in Fig. 5 shows the specific effect of connecting the terminal board to the wires through the clamp of the double wire equipment. After the lower end of the terminal board connecting portion 202 is fixed together with the terminal board 104, the wire connecting portion 201 of the double-conductor equipment clip will protrude from the top of the pressure equalizing ring 103, so that the wire connecting portion 201 will The connected wires will also be located above the pressure equalizing ring 103, thereby meeting the requirement for a safe clearance. In addition, due to the reduction of aluminum plates, the construction difficulty and construction investment are reduced, which better meets the requirements of substation wiring.
