Abstract
The utility model provides a high voltage basin type insulator with a metal insert. The high voltage basin type insulator with the metal insert is mainly composed of the metal insert, a vent hole, a sealing groove, a flange and a basin shaped insulating casting body, and is used for a gas insulating sealing composite apparatus with a rated voltage of 550kV. The metal insert is grounded and is internally provided with a through hole; and a coil lead wire of the composite apparatus penetrates through the through hole. A circumference surface of the metal insert is in an arc transition state, so as to guarantee that an electric field between a high and low voltage of the insulator is evenly distributed. The vent hole is arranged on a curved surface of the basin shaped insulating casting body, so as to ensure that a pressure in a chamber respectively at two sides of the basin type insulator is consistent with each other. The sealing groove is internally provided with a sealing ring; the flange is connected with the high voltage; the flange is connected with the high voltage; two sides of the flange is added with a metal flange then is fastened with a screw; and the sealing performance of the gas in the basin type insulator chamber is ensured. The high voltage basin type insulator with the metal insert has the advantages of being simple and reasonable in structure, good in sealing performance, high in mechanical strength, uniform in electric field distribution, and etc..
Description
Technical field
The utility model relates to a kind of disc insulator, especially relate to a kind of high pressure disc insulator with metal insert, the gas-insulating and fully-enclosed combined electrical apparatus (GIS) that is 550kV for rated voltage, plays insulation and supporting role, belongs to high-tension insulator technical field.
Background technology
Due to the reason such as land used anxiety and land price rise of urban planning, traditional open type power plant construction is more and more not suitable with demand, gas-insulating and fully-enclosed combined electrical apparatus (GIS), because floor space is little, power supply reliably, is not subject to the features such as external environmental interference, is widely used in the power grid construction in city gradually.In order to reduce the loss of electric energy in transmission of electricity process, the transmission of electricity grade of transmission line need to be improved.For high voltage switchgear, the height of its electric pressure depends primarily on every electricity function index and the mechanical performance index of insulator, and electric pressure is higher, just higher to the requirement of insulator.
The insulator of high voltage switchgear not only will have enough insulation distances, also has extremely strict requirement to its inside and along the Electric Field Distribution of face.The inserts of disc insulator needs and epoxy resin is combined closely, otherwise, when mechanically stressed, probably produce gap.In the time of the inserts of design disc insulator, also need to consider the Electric Field Distribution of insulator inside on the other hand.
Summary of the invention
Problem to be solved in the utility model is: the problem existing for prior art, a kind of high pressure disc insulator with metal insert is provided, solve existing disc insulator along face non-uniform electric, sealing property the problem such as low and bad mechanical strength.
In order to address the above problem, the utility model adopts following technical scheme:
With a high pressure disc insulator for metal insert, mainly formed by metal insert, air vent hole, seal groove, flange and peviform insulation pouring body, described metal insert ground connection, described flange connects high pressure.
In the middle of described metal insert, have through hole, the coil lead of gas-insulating and fully-enclosed combined electrical apparatus passes from through hole.
The periphery of described metal insert is arc transition shape, ensures that the Electric Field Distribution between disc insulator high and low pressure is even.
The end face of described metal insert has counter sink and screwed hole, is connected by screw, and ensures the mechanical strength of disc insulator.
Described air vent hole is positioned on the curved surface of peviform insulation pouring body, ensures that disc insulator both sides air chamber pressure is consistent.
In described seal groove, be placed with sealing ring, make the air chamber of disc insulator there is good sealing.
The both sides of described flange add metal flange and use screw fastening.
Between described metal insert and flange, have epoxy resin, making has enough insulation distances between disc insulator high and low pressure.
