Abstract
The invention discloses a voltage transformer for a GIS (Gas Insulated Switchgear). The voltage transformer for the GIS comprises a tank body and a GIS body; a basin type insulator is fixedly arranged on a tank body flange opening; the voltage transformer is connected with the GIS through a basin inlay which is arranged on the basin type insulator; an open-close device is arranged between the basin inlay and the GIS body; an insulated transmission rod is connected to the open-close device; combination and separation of the open-close device are achieved by operating the insulated transmission rod and accordingly disconnection or communication of the GIS and the voltage transformer are achieved. Opening the open-close device or not is achieved by operating the insulated transmission rod which is connected with the open-close device and the open-close device is connected with the GIS through the basin inlay, so that when the insulated transmission rod is operated to drive the open-close device to be opened, the voltage transformer is disconnected with the GIS; on the contrary, the voltage transformer is communicated with the GIS. According to the voltage transformer for the GIS, the open-close device is arranged inside the voltage transformer, so that the GIS is avoided being detached or assembled from the GIS when a pressure resistant test is performed after a predelivery test and field installation.
