The invention relates to the field of switch equipment, in particular to a solid-sealed polar pole with primary and secondary deep fusion. The solid-sealed polar pole comprises an insulating shell, wherein and the interior of the insulating shell is provided with a primary switching circuit which comprises an incoming line connecting end, a vacuum arc-extinguishing chamber, a flexible connector and an outgoing line connecting end; a secondary monitoring circuit which comprises a first voltage sensor arranged in the insulating shell, wherein the high-voltage side of the first voltage sensor iselectrically connected with the incoming line connecting end, and the low-voltage side of the first voltage sensor is connected with external secondary equipment; and a second voltage sensor which isarranged in the insulating shell, wherein the high-voltage side of the second voltage sensor is electrically connected with the outgoing line connecting end, and the low-voltage side of the second voltage sensor is connected with the external secondary equipment. According to the solid-sealed polar pole, the sensor can directly obtain data from a monitoring point, and monitoring equipment and a wire are prevented from being exposed to an external environment, so that the influence in a data acquisition process is avoided, and the monitoring accuracy is improved.
Description
technical field [0001] This application relates to the field of switchgear, in particular to a solid-sealed pole with primary and secondary deep fusion. Background technique [0002] The solid-sealed pole is to embed the vacuum interrupter and circuit breaker-related conductive parts into the solid insulating material that is easy to solidify to form a pole, so that the entire circuit breaker pole becomes an integral part, and has been widely used at present. . The solid-sealed pole includes a primary and secondary fusion solid-sealed pole. The primary and secondary fusion refers to: the primary switch circuit is the main circuit, the secondary monitoring circuit is an auxiliary circuit for controlling the primary switch circuit, and the primary switch circuit is only The circuit formed by the interconnection of electrical equipment directly involved in the manufacture, transmission, transformation, and use of electric energy; the secondary monitoring circuit refers to the ...
