Embodiment Construction

[0012] attached figure 1 It is a specific embodiment of the present invention. The inventive 1100kV high-voltage 11000A high-current outlet bushing includes a central conductor 1, a shielding flange 2, a support insulator 3, a sealing ring 4, a flange 5, a ground shield 6, an intermediate shield 7, and a hollow composite insulator 8, Upper shield 9 and terminal 10. The central conductor 1 is connected to the terminal 10 through screws, and both contact surfaces are silver-plated to improve the flow capacity. The inner and outer surfaces of the other end of the central conductor 1 are silver-plated; the ground shield 6 is connected to the flange 5 through screws, One end of the supporting insulator 3 is connected to the flange 5 through a screw, and the other end is connected to the intermediate shield 7 through a screw, and then the intermediate shield 7 is matched with the shielding flange 2 and then connected through screws. Connect the flange 5 and the hollow composite in...

Abstract

The invention relates to a 1100kV high-voltage 11000A high-current lead-out bushing. The 1100kV high-voltage 11000A high-current lead-out bushing includes a center conductor, a shielding flange, a support insulator, a sealing ring, a flange, a grounding shielding component, a middle shielding component, a hollow composite insulator, an upper shielding component and a wiring terminal; after being plated with silver, an end surface of the center conductor is connected with the wiring terminal through a bolt; the grounding shielding component and the middle shielding component are connected together through the support insulator, and thereafter are fixed to the flange. According to the 1100kV high-voltage 11000A high-current lead-out bushing of the invention, a grounding shielding component and middle shielding component-combined uniform electric field distribution mode is adopted, and therefore, an insulation level can be improved; two ends of the center conductor are plated with silver, so that current through-flow capability can be enhanced; and the wiring terminal is shielded by the upper shielding component, so that the corona initial voltage level of the lead-out bushing is improved. With the 1100kV high-voltage 11000A high-current lead-out bushing of the invention adopted, the operation reliability of power transmission equipment can be improved, and the transmission of large-capacity electric power can be improved.

Description

technical field [0001] The invention relates to a 1100kV high-voltage 11000A high-current outlet bushing structure, which is applied to 1100kV extra-high voltage circuit breakers and combined electrical appliances. Background technique [0002] With the continuous advancement of my country's power system technology, the research and development strength of major high-voltage electrical appliance manufacturing companies continues to increase, the high-voltage switch structure is more reasonable, and the performance is more reliable. my country already has enough strength to carry out research and development and production of ultra-high voltage and ultra-high voltage electrical appliances; and , with the strengthening of the country's economic strength, the continuous implementation of major national construction projects and the development of the western region, the demand for high-voltage switchgear is also increasing, and the voltage level is gradually increasing from 330kV...
