Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulation shields, in particular to a substation adjustable terminal strip insulation shield. BACKGROUND

[0002] In the electrical system of the substation, the terminal strip is a key component for electrical connection, used for connecting, distributing and switching the wires of different lines. Since the terminal strip is exposed to the complex environment of the substation for a long time, it is easy to be affected by dust, moisture, foreign matter touching, etc., which may cause short circuit, electric leakage and other safety accidents. Therefore, the protection effect and adaptability of the insulation shield as an important protection device for the terminal strip are directly related to the operation safety and stability of the substation.

[0003] At present, the common substation terminal strip insulation shield on the market has obvious defects. The existing insulation shield is mostly an integrated structure with fixed length, which can only adapt to terminal strips of specific length. However, the length of the terminal strip in the substation varies according to the connection requirements of the line, ranging from a few tens of centimeters to several meters. When the length of the terminal strip exceeds the adaptation range of the shield, part of the terminal cannot be effectively protected. If the length of the terminal strip is shorter than the shield, the shield will sway due to the excess part, affecting the protection stability. In addition, if the existing shield needs to cover a long terminal strip, it is usually spliced by simply stacking or buckling connection. However, the connection structure is loose, and under the conditions of daily inspection and equipment vibration in the substation, the spliced part is easy to loosen or even separate, resulting in exposure of the terminal strip. This not only reduces the insulation protection effect, but also may cause equipment failure due to the falling of the shield. At the same time, the fixed length shield requires the enterprise to stock a variety of specifications, increasing the procurement and storage costs. Therefore, it is urgent to improve. SUMMARY
