国家电网公司新研发的国内首个配送式二次设备舱——浙江绍兴220 kV袍南站智能变电站长12.2 m、宽2.44 m、高2.89 m,只有集装箱大小,从厂方运到绍兴以后插上光缆、电缆与一次设备一对接即可投入使用。在电力系统中,直接用于发电、用电的设备被称为一次设备,而不和电直接发生关系,对一次设备进行控制、保护的设备是二次设备。实现标准化装配——配送式智能变电站取消主控室,以预制式组合二次设备舱代替。作为一种新型的电力设备结构载体,预制舱就是把变电站二次设备在厂里做好以后,将成品运到各地,与一次设备对接后马上就能用采用标准化连接——预制光缆实现即插即用,一次设备与二次设备、二次设备间的光缆、电缆能够迅速连接,降低现场施工安全风险。
State Grid Corporation newly developed the first distribution of the second equipment compartment - Zhejiang Shaoxing 220 kV Pao South Station intelligent substation 12.2 m long, 2.44 m wide and 2.89 m high, only the size of the container, shipped from the factory to Shaoxing after the plug On the cable, cable and a device can be put into use. In the power system, the equipment directly used to generate electricity and electricity is called a primary equipment, and does not have a direct relationship with electricity. A primary equipment is controlled and the protective equipment is a secondary equipment. Achieve standardized assembly - Distribution intelligent substation cancel the main control room, with prefabricated combination of secondary equipment bay instead. As a new type of power equipment structure carrier, the prefabricated cabin is to make the substation secondary equipment well in the factory, and the finished products are transported to all over. Once the equipment is docked, the standardized connection can be used - the prefabricated optical fiber cable That is to say, the cables and cables between the primary equipment and the secondary equipment and the secondary equipment can be quickly connected, reducing the risk of on-site construction safety.
