Abstract
本发明公开了一种220kV配电装置的布置结构。常规变电站的220kV侧主母线使用比较多的是管型硬母线及软导线，由于裸导线是布置于空气中，因此导线相间距离必须保证足够的安全距离，进而增加了配电装置的占地面积。本发明的特征在于，从GIL管型母线上分别垂直引出A、B、C三相套管，GIL管型母线的一侧设有三个处于同一直线上的隔离式断路器；所述的三个隔离式断路器与GIL管型母线平行布置，所述的三个隔离式断路器分别与GIL管型母线的A、B、C三相套管采用软导线连接。本发明一方面大大减少了配电装置的占地面积，另一方面提供了一种高可靠性、低故障率、维护量少的配电装置布置形式。
The invention discloses an arrangement structure of a 220kV power distribution device. The 220kV side main busbars of conventional substations mostly use tubular hard busbars and soft wires. Since the bare wires are arranged in the air, the distance between the wires must ensure a sufficient safety distance, which increases the footprint of the power distribution device. .

背景技术 Background technique
常规户外变电站220kV配电装置大多采用常规户外设备。220kV常规设备数量多、外型尺寸大、占地广，设备之间的连接点多，造成故障的隐患点比较多。设备受气候环境等因素影响容易出现锈蚀，缩短设备使用寿命，在目前变电站中使用了大量的隔离开关设备，需要经常进行检修维护，大大影响供电可靠性。 Most of the 220kV power distribution devices in conventional outdoor substations use conventional outdoor equipment. 220kV conventional equipment has a large number, large size, and a large area. There are many connection points between equipment, and there are many hidden dangers that cause failures. The equipment is prone to rust due to factors such as climate and environment, which shortens the service life of the equipment. At present, a large number of isolating switch equipment is used in the substation, which requires frequent inspection and maintenance, which greatly affects the reliability of power supply.
在常规变电站的220kV侧主母线，现阶段使用比较多的有管型硬母线及软导线两种导线，这两种型式的导线都是裸露在空气中布置的，特别是在一些污染比较严重的地区，就需要经常进行清洁维护。由于裸导线是布置于空气中，因此导线相间距离必须保证足够的安全距离，进而增加了配电装置的占地面积。 In the 220kV side main busbar of a conventional substation, at this stage, more tubular hard busbars and flexible conductors are used. These two types of conductors are laid out in the air, especially in some seriously polluted areas. Areas require frequent cleaning and maintenance. Since the bare wires are arranged in the air, a sufficient safety distance must be ensured between the phases of the wires, thereby increasing the footprint of the power distribution device.
