[0002] In the power transformation and distribution service, the measuring substation plays a vital role. It is responsible for real-time monitoring of various parameters in the power grid, such as voltage, current, power factor, etc., providing an important basis for the operation and dispatching, fault analysis and optimization decision-making of the power grid. By measuring the data of the substation, power companies can timely understand the operation status of the power grid, find potential problems and take measures to solve them, and ensure the safe, stable and efficient operation of the power grid. The main equipment of the measuring substation includes transformers, switchgear, voltage transformers, current transformers, measuring instruments, etc. Among them, the voltage transformer is mainly used to measure the voltage of transmission lines and substations, and to detect the operating status of power equipment.

[0032] By adopting the above technical scheme, the voltage transformer body 3 is installed on the mounting base 1 through the fixed base 501, and the fixing screw 504 passes through the socket 510 in the movable ring 503 and is threadedly connected with the fixed base column 507 at the bottom, so that the abutment plate 505 presses the movable hole 502, and the clamping ring 506 on the fixed base column 507 is clamped into the clamping groove 509 of the movable ring 503. In order to prevent the movable ring 503 from moving, a plurality of protrusions 508 are arranged at the bottom of the abutment plate 505, which can increase the friction between the abutment plate 505 and the movable hole 502.
