The cabinet body is divided into a left chamber and a compensation chamber by a vertical separation plate at the middle of the cabinet body. A transverse plate is arranged in the left chamber to divide the left chamber into a metering chamber and a lower cabinet chamber. An ammeter, a voltmeter, a three-phase four-wire electric energy meter and a concentrator are arranged in the metering chamber. An intelligent reactive power controller, a miniature circuit breaker, a current transformer, an intelligent low-voltage combination switch and a capacitor are arranged in the compensation chamber. The current transformer is connected with a controller. The controller is connected with a wireless communication module. A knife switch, a contactor and a lightning arrester are arranged in the lower cabinet chamber. According to the technical scheme of the utility model, by means of the low-voltage reactive compensation power distribution cabinet, when a human body gets an electric shock, the protection against indirect contact is enabled. Meanwhile, the reactive power is effectively compensated and the power quality is improved. The loss is lowered and the data of the power distribution operation are provided. In addition, the low-voltage reactive compensation power distribution cabinet, which has the advantages of small size, light weight and convenient installation, integrates the functions of protection, metering, measurement, compensation, communication and lightning protection as a whole and is a modern and novel product.
