This application provides a 550kV vertical structure insulated metal-enclosed switchgear, belonging to the technical field of enclosed switchgear. The technical solution is a 550kV vertical structure insulated metal-enclosed switchgear, including an insulating bushing electrically connected to an isolating grounding switch. A vertical tank for closing resistors is located outside the isolating grounding switch, containing a closing resistor. Two parallel vertical tanks for vacuum interrupters are located outside the closing resistor tank, each containing a 252kV vacuum interrupter, and each 252kV vacuum interrupter is connected in parallel with a capacitor. The moving contacts of the two 252kV vacuum interrupters are connected in series via a connecting conductor. A driving mechanism is located at the bottom of both the closing resistor tank and the vacuum interrupter tank, enabling synchronous opening and closing of the closing resistor and the 252kV vacuum interrupters. The beneficial effect is that it ensures synchronous closing of the 252kV vacuum interrupters connected in series.
