Embodiment Construction

[0032] See figure 1 1. A two-remote power monitoring and fault rapid diagnosis system (hereinafter referred to as the system) of the present invention is mainly composed of 5 major parts such as a sensor group, a switch state output device, a current temperature display instrument, a communication machine, and a background server. The positional connection relationship and signal direction between them are: the sensor group is installed on the cable that needs to be monitored; the switch state output device is installed at the position of the switch or relay; the current and temperature display is generally installed at a convenient viewing position; It is installed in a special electric cabinet; the background server is deployed in the power grid computer room. The sensor group transmits the collected temperature and current values ​​to the current temperature display instrument and the communicator through the optical fiber. The communicator receives the data sent by the sen...

Abstract

A telemetering and remote signaling power monitoring and fast fault diagnosis system is composed of a sensor group, an on-off state output device, a current and temperature display instrument, a set of communication equipment and a background server. The server group is installed on a cable needing to be monitored; the on-off state output device is installed in the position of a switch or a relay; the current and temperature display instrument is installed in a position convenient to view; the communication equipment is usually installed in a special electric cabinet; the background server is arranged in a power grid machine room. The sensor group sends acquired temperature and current values to the current and temperature display instrument and the communication equipment through optical fibers, and the communication equipment receives data sent by the sensor group and acquires the on-off state and then sends the data and the on-off state to the background server. The telemetering and remote signaling power monitoring and fast fault diagnosis system integrates the modern computer technology, the communication network technology and other technologies, equipment on a power distribution network can be remotely metered and signaled in real time, and the telemetering and remote signaling power monitoring and fast fault diagnosis system is a power monitoring and diagnosis device scientific in structure, convenient to use and safe to operate.

Description

Technical field: [0001] The invention relates to a two-remote power monitoring and fault rapid diagnosis system, which is a remote monitoring, display and alarm system for power network nodes and equipment in the power industry. The utility model belongs to the technical field of electric power monitoring and diagnosis equipment. Background technique: [0002] At present, in my country's electric power, the large-scale interconnection and the independent provincial power grid are interconnected, and there are more electric power and power station constructions, so that there are many hidden safety hazards and power failures in the power grid lines that cannot be detected and eliminated in time. In terms of detection and early warning of power failures, There are still many deficiencies and loopholes. The safe operation of power equipment is the first defense system to avoid major power grid accidents, and the normal and safe operation of power line node stations is one of th...
