Abstract
A communication management unit of a distribution management network is to solve the technology problems that the impact resistance, anti-vibration performance and reliability of the prior communication management unit are poor. The technology scheme is employed as follows: the communication management unit comprises a housing and a circuit structure on the circuit board arranged in the housing; the circuit structure comprises a power supply circuit, a control circuit, and a serial interface circuit and a network interface circuit connected with the control circuit; and the characteristic is that the inner wall of the housing is provided with a damping sheet, and the wall thickness of the housing is from 5 to 8 mm. The technology effects are provided as follows: the damping sheet is employed, thereby the impact resistance, anti-vibration performance and reliability of the communication management unit are effectively raised, the contact reliability components and socket connectors is raised, the information collected by the communication management unit on site in a low voltage distribution automatic system is more accurate and reliable, background or main station commands are better transmitted to each measurement and control apparatus, local or remote control is realized, and the low voltage distribution system works better.
Description
Technical field
