Abstract

The invention discloses a novel intelligent AC metal closed switching device, which comprises a shell, a cable and a medium-voltage AC vacuum circuit breaker, wherein the cable and the medium-voltage AC vacuum circuit breaker are arranged in the shell and mutually connected, the medium-voltage AC vacuum circuit breaker comprises a circuit breaker body and a front-mounted device which are connected through an optical fiber, a medium-voltage current sensor is embedded in the circuit breaker body, the front-mounted device is arranged on the shell, the front-mounted device comprises a controller, a comprehensive protection measurement and control device, an electric energy meter, a switch cabinet comprehensive indicator, a screen element, a wireless transmitting and receiving unit and a Beidou chip which are mutually connected, and the controller is connected with a temperature detector, a humidity detector, a heater, a cabinet isolation measurement and control device, a fan, a cabinet door monitor and a live detection device. According to the invention, the medium-voltage current sensor is embedded in the circuit breaker body, and electrical isolation of the circuit breaker body and the front-mounted device is realized, so that the design is modularized, the assemble difficulty is reduced, the number of failure points is small, and the failure rate is low.

Description

[0001] Technical field: [0002] The invention relates to the field of control and protection in a power distribution system, in particular to a novel intelligent AC metal-enclosed switchgear. [0003] Background technique: [0004] Armored removable AC metal-enclosed switchgear is mainly used in power plants, small and medium-sized generators for power transmission, industrial and mining enterprises and institutions, and secondary substations of power systems for power reception, power transmission, and large-scale high-voltage motor starting. For control, protection and monitoring purposes. With the advancement of power grid construction, armored removable AC metal-enclosed switchgear has been more and more widely used. [0005] After long-term technical improvement, the appearance size, structure and function of this product have undergone major changes compared with the previous ones. Especially in recent years, in order to meet the needs of market development, cabinets a...
