Detailed Description
The present invention will be further explained with reference to the drawings and examples. Where the description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus consistent with certain aspects of the invention, as detailed in the appended claims.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of the terms "comprising" or "including" and the like in the present application is intended to cover the elements or items listed before or after the term and their equivalents, without excluding other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
The GIL uses the built-in basin-type insulator function device, the tank body junction is connected with tank body flange II4 through tank body flange I2, tank body flange I2 is connected and fixed with tank body flange II4 through fastener 5. The inner side of the tank body flange I2 is provided with a groove, the groove is provided with a baffle 3, and the baffle 3 is arranged in the tank body flange I2 through bolts. The outer edge of the basin-type insulator 1 is inserted into the groove, one side of the basin-type insulator 1 is tightly attached to the flange I2 of the tank body, the other side of the basin-type insulator 1 is in contact with the baffle 3, and the basin-type insulator 1 is limited through the baffle 3. After installation the basin insulator is between the contacts 8 of the conductor 7 in the tank. The baffle limits that the basin-type insulator can not fall off from the flange, and the butt joint of the bus on site is facilitated. And only the tank body butt flange is provided with the fastening bolt for handle connection, and the basin-type insulator is not provided with the handle connection bolt, so that the assembly is convenient; the built-in basin-type insulator is positioned between the two flanges and does not bear the installation stress, so that the basin-type insulator is prevented from being irreversibly damaged due to the external installation force.
The inner walls of the front and rear tank bodies at the position of the basin-type insulator 1 are provided with particle trapping devices 9, and the particle trapping devices 9 are metal plates with holes. A gap is reserved between the particle trapping device and the tank body, and under the working condition that the bus is electrified, the potential of the particle trapping device is the same as the potential of the tank body and is the ground potential, so that the gap between the particle trapping device and the tank body forms an area without electric field force. When the power-on operation is carried out, if foreign matters floating and indefinite under the action of an electric field force move to an area without the electric field force in the bus, the foreign matters lose the action of the electric field force and are precipitated in the area, so that the effect of trapping particles is achieved, the insulating property of the built-in basin-type insulator is improved from the side, and the overall reliability of the product is improved.
And sealing rings 6 are arranged at the positions of the tank body flange I2 and the tank body flange II 4. The number of the sealing rings 6 is three, one is arranged between the tank body flange I2 and the tank body flange II4, the other is arranged between the basin-type insulator 1 and the tank body flange I2, and the other is arranged between the basin-type insulator 1 and the tank body flange II 4. And a double-channel sealing structure is arranged between each air chamber and the air chamber and between each air chamber and the atmosphere. And if the basin-type insulator breaks down, the sealing between the abutting flanges can also ensure that insulating gas does not leak into the atmosphere, so that the overall safety performance of the GIL is greatly improved.
