用于更换绝缘子的装置及后卡
摘要：
一种用于更换绝缘子的装置及后卡，包括前卡（60）、后卡（10）、和绝缘拉板（40），后卡（10）包括直线段（11）和弯曲段（12），直线段（11）侧面设有与丝杠组件（20）相匹配的凹圆通孔（13），丝杠组件（20）从后卡（10）的外侧穿过后卡（10）的凹圆通孔（13）后，与绝缘拉板（40）固接，弯曲段（12）侧面中央设有用于夹持后联板（50）的空位（14），而在垂直于该空位（14）处设有定位孔（15）；前卡（60）的一端与前联板（70）固接，另一端与绝缘拉板（40）固接。使用该后卡，增大了带电作业有效空气间隙和丝杠可调度，保证供电可靠率，使220kV线路安全、稳定、可靠地运行。
摘要（英）：

Disclosed are an apparatus and a back card used for replacing an insulator. The apparatus used for replacing an insulator comprises a front card (60), a back card (10) and an insulation drawing plate (40). The back card (10) comprises a linear section (11) and a bending section (12); the side surface of the linear section (11) is provided with a recessed circular through hole (13) coupled to a leading screw assembly (20); after the leading screw assembly (20) passes through the recessed circular through hole (13) of the back card (10) from the outer side of the back card (10), the leading screw assembly (20) is fixedly connected with the insulation drawing plate (40); the center at the side surface of the bending section (12) is provided with a vacancy (14) for clamping a back connection plate (50); a location hole (15) is arranged at the position perpendicular to the vacancy (14); and one end of the front card (60) is fixedly connected with a front connection plate (70), and the other end is fixedly connected with the insulation drawing plate (40). After the back card is employed, an effective air gap in live-line work is increased, the adjustability of the leading screw is enhanced, the power supply reliability is guaranteed, and a 220 kV line runs safely, stably and reliably.
