Project Name: Design of Energy-saving Reconstruction Project of Xihu Gushan Night Scene Lighting
Reporting unit: Yuemiao Management Office, Hangzhou West Lake Scenic Area
Hangzhou Urban and Rural Construction Design Institute Co., Ltd.
"The victory of the West Lake, the clear lake is not as good as the rain lake, the rain lake is not as good as the night lake." Night tour of the West Lake, chasing time, crossing the water for more than a thousand years, watching the foot of the lonely mountain, Lin and Jing on the Mei Fu; Pinghu, Xu Wenchang began to fight poetry; Qingxing Palace, Emperor Qianlong looked at the lake... Gushan night scene is really Everywhere is elegant.
Located in the northwest corner of West Lake, Gushan is opposite to the bustling center of Hangzhou. It is surrounded by water and is unique. It is the largest island in the lake and the only natural island. Lonely Shandong is connected to the Baidi, and the west is connected to the Xiqiao Bridge. It is shaped like a cow lying in the water and floating in the blue waters of the West Lake. In order to highlight the human landscape and natural essence of the Lonely Mountain, the Yuemiao Management Office has been deploying landscape lights in the Lonely Mountain area since 1990. In 2004, the surrounding mountains were illuminated. In 2008, the opinions of comprehensive experts and citizen tourists were further upgraded. The lights of the gardening and greening were highlighted, and the green light was replaced by warm white light to restore the true color of the plants. The full golden light source created a picture atmosphere.
On June 24th, 2011, West Lake became a world cultural landscape heritage. There are 4 heritage sites in the Gushan Mountain Scenic Area, which also puts higher requirements on the night scene lighting: on the one hand, it is in the background of the "ink painting" Under the same, it is in line with the characteristics of various heritage sites to create a night light effect. On the other hand, it must practice the concept of environmental protection and advocate the ecological West Lake. The night scene lighting of Gushan has undergone many years of changes, and the following problems have existed: First, the aging of the lamps is serious and the power consumption is too large; second, the selection of some buried lights is not suitable for the site conditions; the third is the growth and change of vegetation, and the The lighting needs to be re-adjusted. In view of this, in 2011, the Yuemiao Management Office proposed to upgrade and renovate the energy saving and emission reduction of the landscape lighting along the coast of Beili Lake and the landscape lighting of Pinghu Qiuyue.
High Voltage Main Power Transformer
The main transformer, which is the main step-down transformer used for power transmission and transformation in a unit or substation, is also the core part of the substation.
The main transformer is composed of the following aspects:
1. Body: The body directly converts electromagnetic energy, which is composed of iron core, coil, lead wire, insulation, etc.
2. Oil tank and cover: mainly composed of box, cover, bottom and accessories (such as 50 valve, oil sample valve, oil drain plug, grounding bolt, etc.).
3. Protection device: mainly composed of oil conservator, oil meter, oil purifier, gas relay, Moisture Absorber, thermometer, Pressure Relief Valve, etc.
4. Cooling mode: oil immersed self cooling, oil immersed air cooling, strong oil water cooling, strong oil air cooling.
5. Outgoing line bushing: It is composed of 25/300 cable bushing and BF-6/2000, BF-1/1000, BF - l/600 and BF-1/300 bushings.
6. 25 # or 45 # transformer oil is used as transformer oil to increase insulation strength and cool down the transformer;
