Natural disasters, such as cyclones, earthquakes, landslides, etc., or manmade damages, such as structural member's theft, terrorist attacks, etc., can cause collapse of transmission line towers. If these are not restored in time, there will be monetary loss to utilities as well as loss of service to consumers leading to societal impact. Generally, permanent restoration takes several weeks. Hence, a temporary solution for quick retrieval of power transmission is required. This invention provides a temporary support structural system comprising light weight guyed masts (1) made of readymade robust modules (6 and 7), easy to connect connection system, two pin gimbal joint (8) and easy to construct foundation system (9 and 10). The invention is flexible enough to develop various configurations for single or double circuit transmission lines. It is also scalable and can be used for 33 to 800 kV transmission lines.

The present application relates to the technical field of double circuit line electric field detection, in particular to a double circuit line electric field detection and early warning method and system. The method has the following steps: S1, obtaining an electric field distribution model of a target area based on theoretical calculation; S2, establishing a regional electric field model; S3, obtaining a reconstructed electric field distribution model; S4, obtaining the real-time spatial coordinates of a target person; S5, based on the reconstructed electric field distribution model, obtaining an electric field distribution set at a set region set with the real-time spatial coordinates as the reference, and performing a warning action when there is a value exceeding the set alarm threshold in the electric field distribution set. The system is used to implement the above method. The present application can preferably realize early warning of electric field overlimit based on theoretical values and field measured values.
