Solid-sealed polar pole for primary and secondary deep fusion

Abstract

The invention discloses a solid-sealed polar pole for primary and secondary deep fusion, which comprises an insulating shell, and is characterized in that the insulating shell is internally provided with a vacuum arc-extinguishing chamber, an electricity taking device, a current detection device, a first voltage sensor, a second voltage sensor, a metal shielding net, a first conductive insert, a second conductive insert, a third conductive insert and a fourth conductive insert; the insulating shell is provided with an inlet wire electric connecting piece and an outlet wire electric connectingpiece. According to the invention, the power taking device, the current sensor and the voltage sensor can be integrated in the pole; a capacitor electricity taking function can be achieved, the current condition can be monitored in real time, the two voltage sensors poured in the pole can monitor the voltage on the two sides of the fracture of the vacuum arc-extinguishing chamber, monitored voltage and current signals can be used for estimating the equipment state and supporting feeder automation, and the purpose that primary equipment and secondary equipment are deeply fused in one step is achieved.

Description

technical field [0001] The invention relates to the field of medium-voltage switchgear, in particular to a solid-sealed pole with primary and secondary deep fusion. Background technique [0002] In order to ensure the stable operation of the traditional vacuum circuit breaker, current sensors and voltage sensors need to be installed outside the vacuum circuit breaker. Due to the large volume of the current sensor and the voltage sensor, the vacuum circuit breaker occupies a large volume and the cost is high. At the same time, the country is now vigorously promoting the construction of the distribution network. In this process, it is necessary to improve the standardization and integration level of the primary and secondary equipment of the distribution, improve the operation level of the distribution equipment, and solve the primary and secondary problems faced in the construction of distribution automation. Urgent issues such as interface compatibility and scalability. In ...
