The invention discloses a multifunctional observation test tower suitable for line galloping and insulator performance detection. The multifunctional observation test tower comprises two glaze towers, a lead wire is suspended between the two glaze towers, the lad wire is provided with a galloping detection deicing mechanism, the galloping detection deicing mechanism comprises two n-shaped frames, the two n-shaped frames are connected through an upper crossbar and a lower crossbar, and the upper crossbar is provided with a vibration sensor. The application is convenient, a line is protected, the safety and efficiency are high, an insulator on the transmission line can be remotely monitored, pollution flashover alarm information can be obtained in advance, the insulator is replaced or maintained conveniently, the risk is low, the cost is economic and reasonable, the measurement is accurate, the measurement precision is high, the anti-interference capability is also high, and at the same time, the safety and the reliability of a power grid are also improved.
