Test control module for power distribution network carrier communication

Abstract

The invention relates to a carrier communication measuring and controlling module of a distribution network, which comprises a carrier communication template, a measuring and controlling template and a power supply template. A microprocessor system, a modem, a programmable array, a self-adapting coupler, a transceiver commutation circuit and a carrier communication signal input interface are arranged on the carrier communication template; the microprocessor system, an optoelectronic isolating and controlling output interface circuit, a switching value input interface, a control relay, a current transformator CT, an I / V conversion transducer, a current detection combination circuit composed of an S / H current sample circuit and a voltage detection combination circuit composed of a pressure transformator PT, a V / V conversion transducer and an S / H voltage sample circuit are arranged on the measuring and controlling template; an alternating current power input interface is arranged on the power supply template; the interface is sequentially connected with a rectification circuit, a filter circuit, a voltage regulator circuit, an output circuit and a power protection automatic-control circuit. The carrier communication measuring and controlling module is especially suitable for the remote measurement and control of equipment such as a carrier communication system switch, a transformer, etc., is convenient for installation, debugging, operation and maintenance, and also can be used for the remote measurement and control of automation equipment in other various communication systems.

Description

technical field [0001] The invention belongs to an automatic measurement and control device, in particular to a distribution network automation carrier communication measurement and control module. This module can be used for the switch of the carrier communication system, the remote measurement, remote control, remote signaling and remote adjustment of the transformer. It can also be used for remote detection and control of switches and transformers in optical fiber communication, wireless and other communication systems. Background technique [0002] At present, in the 10kV distribution network feeder automation system, a large number of switches and transformers supporting measurement and control devices are used. These devices have the following problems: most of the measurement and control devices are installed outdoors separately, and special communication lines need to be erected, and the working power supply of the outdoor devices needs to be configured. This kind ...
