Draining device of underground transformer substation

一种地埋变电站的排水装置

Abstract

本实用新型公开一种地埋变电站的排水装置,排水装置包括:地埋箱体,在地埋箱体底面上有挡水围堰,挡水围堰与地埋箱体侧壁下部形成导水通道,导水通道连通集水坑,在集水坑内设置有水泵,水泵的排水口连接排水管的一端,排水管的另一端穿过箱体侧壁插入排水管网中;在挡水围堰上面支撑有底板,在底板上支撑电器设备和变压器。本实用新型有益效果:地埋箱体内设置有导水通道,导水通道与集水坑连通,从导水通道汇集到集水坑内的水被水泵及时抽出,确保地埋箱体内的水位低于警戒水位;另外,地埋箱体内的电器设备被底板架高支撑,避免接触地埋箱体内的积水,确保地埋箱体内的电器设备安全运行。
The utility model discloses a draining device of an underground transformer substation. The draining device comprises a buried box body, a water retaining coffer is disposed on the bottom face of the buried box body, a water guide channel is formed between the water retaining coffer and the lower part of the side wall of the buried box body and is communicated with a water collection pit, a water pump is arranged inside the water collection pit, a water outlet of the water pump is connected with one end of a water drainage pipe, the other end of the water drainage pipe penetrates through the side wall of the box body and is inserted into a drainage pipeline, a base plate is support above the water retaining coffer, and electrical equipment and a transformer are supported on the base plate. The beneficial effects of the draining device are that the water guide channel is disposed inside the buried box body and is communicated with the water collection pit, and water converging from the water guide channel into the water collection pit is timely pumped out by the water pump, thus to ensure that the water level inside the buried box body is lower than a warning water level; and, additionally, the electrical equipment inside the buried box body is elevated and supported by the base plate, so as to avoid contacting accumulated water inside the buried box body and guarantee that the electrical equipment inside the buried box body operates safely.
