Mao Tong is a leading China Galvanized 400KV Steel Structure for Electrical Substation manufacturers, suppliers and exporter. Qingdao Maotong ® Power Tower Co., Ltd. is a factory dedicated to the production and installation of steel tower masts and various steel structures such as chimney tower, lightning protection tower, anemometer tower, training tower, roof process tower, single tube tower, bionic tree, integrated base station, communication tower, monitoring tower, power tower, TV tower, etc.

The substation architecture is the substation

Substation and other outdoor wire, equipment of the main support structure of the general name. It is determined according to the voltage level, scale, equipment layout, construction and operation conditions and local climate conditions. According to the nature of electricity, different voltage levels require a certain distance between the wires, the wires to the ground and the wires to the structures. Therefore, the substation structure is characterized by high columns and small sections, belonging to the structure of large flexibility. In terms of the type classification of technological layout, there are medium layout, half height layout and high layout. Semi-high layout and high layout are mainly used in substation with high voltage level. 

At present, electrified railway traction substation are medium - size layout. In terms of its purpose classification, the structure is divided into wire frame, bus frame, central door frame, corner frame, transformer combination frame, single rod equipment bracket, etc. In terms of the appearance classification of the architecture, the commonly used forms of the architecture are AH type in/out architecture, AP type with lightning rod support in/out architecture, AP type architecture, A? Type architecture, P-type architecture, corner architecture, large shape architecture, with pull line in and out of the architecture. In terms of the stress on the architecture, there are three types of architecture: intermediate architecture, terminal architecture and draw-wire architecture.

The layout form and shape of the architecture are determined by the voltage level, wire and equipment layout of the substation. The material used in the architecture is related to the load borne by the architecture itself. The voltage level of the substation is high, the load borne by the architecture itself is large, and the voltage level is low, and the load borne by the architecture itself is small. The architecture of various materials has its corresponding advantages and disadvantages and scope of application.

Lightning protection equipment for substation

The substation is also equipped with lightning protection equipment, mainly lightning rods and arresters. The lightning rods are designed to prevent the substation from being struck by direct lightning that will discharge the lightning into itself and bring the lightning current to the ground. When the thunder falls on the line near the substation, the thunder wave will enter the substation along the wire and produce overvoltage. In addition, circuit breaker operation can also cause overvoltage. The function of the arrester is to automatically discharge to the ground to reduce the voltage when the overvoltage exceeds a certain limit. After the discharge, the equipment automatically extinguishes the arc to ensure the normal operation of the system. At present, the most used is zinc oxide arrester.
