Abstract

The invention provides an indoor intelligent alternating current metal armoring movable switch device, belongs to the field of intelligent switches and aims at solving the problem that a conventional secondary device in an existing power distribution system is complicated in secondary wire connection and poor in reliability. The data signal output end of a high-voltage electrification sensor is connected with a data signal input end of a high-voltage electrification display module, the communication signal input-output end and a voice signal output end of a central processing unit are respectively connected with a communication signal input-output end of an RS485 communication interface circuit and the voice signal input end of a voice prompting circuit, the first and second control signal output ends of the central processing unit are respectively connected with the control signal input end of the high-voltage electrification display module and the control signal input end of an LED display module, the signal output end of a temperature-humidity sensor is connected with the temperature-humidity data signal input end of the central processing unit, and the data signal output end of a three-phase electric energy metering module is connected with the second data signal input end of the central processing unit. The indoor intelligent alternating current metal armoring movable switch device is mainly applied to the field of power grid power distribution.

Description

technical field [0001] The invention belongs to the field of intelligent switch cabinets. Background technique [0002] With the rapid development of social economy, the demand for electricity load is increasing rapidly. The density of electricity load in the city center has reached 9-11MW / km2, and the power supply capacity of the existing voltage level has reached the saturation limit, which cannot meet the demand for the rapid growth of electricity load. , In order to meet the needs of the incremental development of the distribution network scale, a 20KV grid voltage level is introduced, which can not only alleviate the tension of line corridor resources, but also increase the power supply capacity by 1 time, and expand the power supply radius and power supply range by 2.5 times. Save 50% of land resources and reduce power grid loss by 75%, reduce power grid investment, and increase economic benefits for society and enterprises. The promotion of 20KV power grid and the ma...
