Abstract

The invention relates to a gas insulated switchgear (GIS) combined type voltage transformer. The GIS combined type voltage transformer comprises a pedestal, a shell, a device body, a basin type insulator, a basin type insulator conductor and an electric conductor, wherein the shell is fixed on the pedestal; the basin type insulator is arranged on the top of the shell; the basin type insulator conductor is arranged in the center of the insulator and extends out of the shell; the device body is fixed on the pedestal at the bottom of the shell; the basin type insulator conductor is connected with the device body through the electric conductor; the electric conductor is an elastic electric conductor; the top end of the electric conductor is fixedly connected with the basin type insulator conductor; and the tail end of the electric conductor is moveably connected with the device body, so that on and off of the basin type insulator conductor and the device body are realized. An insulating piece extending from the end part operates the elastic electric conductor to act to contact or not contact with the device body, so that on and off of the voltage transformer are realized. The GIS combined type voltage transformer has a built-in isolating function, is not externally connected with a disconnecting device, is convenient to use and is line with the development direction of miniaturization and light weight of the GIS equipment.

Description

technical field [0001] The invention relates to a voltage transformer, in particular to a GIS combined voltage transformer with a built-in isolation function. Background technique [0002] Voltage transformer is an indispensable electrical appliance for power transmission and power supply systems such as power plants and substations. It is mainly used to supply power to measuring instruments and relay protection devices, to measure the voltage, power and electric energy of the line, or to protect valuable equipment, motors and transformers in the line when the line fails. Metal-enclosed gas-insulated high-voltage switchgear (GIS) is gradually developing towards miniaturization and light weight. When debugging, the voltage transformer usually needs to be disconnected, but it does not have the isolation function and needs an external disconnection device, which is cumbersome to use and large in size, which is not conducive to the miniaturization and lightweight development of...
