Power transmission double-circuit T-shaped line opening and closing tower
The invention relates to a power transmission double-circuit T-shaped line opening and closing tower which is of a double-column structure, two insulation supporting columns are symmetrically installed in the center of the opening and closing tower in the left-right direction, a three-arm type disconnecting switch is installed on each insulation supporting column, each three-arm type disconnecting switch single phase comprises three knife switch arms, and the whole opening and closing tower is provided with 18 knife switch arms in total. Three vertical insulation connecting rods are distributed beside each insulation pillar in a non-contact mode, and each switch blade arm is connected with the corresponding vertical insulation connecting rod. Each switch blade arm is provided with a moving contact, and the tower material on the same plane is provided with a static contact corresponding to the moving contact; a base is installed between the two insulation supporting columns in the horizontal direction, two operating mechanisms are installed on the base and used for controlling the three-arm type disconnecting switches on the left side and the right side respectively, and motion is transmitted to static contacts connected with switch blade arms by adjusting torque of the operating mechanisms so as to complete switching-on and switching-off actions of the disconnecting switches. According to the invention, rapid fault isolation and flexible switching of power supply modes are realized through the opening and closing tower.
本发明涉及一种输电双回T型线路开闭塔，采用双柱式结构，在开闭塔的中心位置左右对称安装两个绝缘支柱，在每个绝缘支柱上均安装有三臂式隔离开关，每个三臂式隔离开关单相均包括3个闸刀臂，整个开闭塔共有18个闸刀臂；每个绝缘支柱旁边无接触分布有3个垂直绝缘连杆，每个闸刀臂与相应的垂直绝缘连杆连接；每个闸刀臂上有动触头，在同一平面的塔材上有与之对应的静触头；在两个绝缘支柱之间沿水平方向安装有底座，在底座上安装有2个操动机构，分别控制左右两侧三臂式隔离开关，通过调整操动机构的力矩，将运动传动给与闸刀臂相连接的静触头，以完成隔离开关的分、合闸动作。本发明通过开闭塔实现了故障的快速隔离故障和供电方式的灵活切换。
