Abnormal operation remote alarm device for distribution transformer distribution room equipment

Abstract

The invention provides an abnormal operation remote alarm device for distribution transformer distribution room equipment. The device comprises a signal data acquisition circuit, a signal data computation and judgment circuit and a remote alarm communication circuit, wherein the signal data acquisition circuit acquires signal data from the transformer distribution room; the output end of the signal data acquisition circuit is connected with the signal data computation and judgment circuit; the output end of the signal data computation and judgment circuit is connected with the remote alarm communication circuit; and the remote alarm communication circuit is connected with a distribution network power supply intelligent control center or mobile phones of electricians on duty. The device for carrying out remote alarm on such real-time detected conditions as transformer overcurrent and equal high / low phase failure of the distribution transformer and 400V distribution system is developed by utilizing the modern computer, monitoring and communication technology. The device has the following advantages: by popularizing and applying the device, the labor intensity of the workers and the unsafety factors can be greatly reduced, the power supply reliability of the distribution system can be improved, the benefits of the power enterprises and the social benefits can be increased, the social reputation of the power supply enterprises can be elevated and the development of the intelligent grid construction technology can be positively pushed.

Description

technical field [0001] The invention relates to a remote intelligent alarm technology for abnormal operation of equipment in a distribution transformer station area, specifically, a remote alarm device for abnormal operation of equipment in a 10kV distribution transformer station area. Background technique [0002] At present, the power system is fully developing smart grid construction, implementing intelligent control, intelligent management, and intelligent analysis of the entire grid. The intelligentization of distribution network has only just started, and it has not been fully popularized and applied due to various reasons. The research on remote alarm technology for abnormal operation of equipment in the distribution transformer station area is also a part of the popularization and application of intelligent distribution network, mainly for distribution transformers and The following 400V power distribution system equipment is running abnormally and remotely alarmed. ...

AI Technical Summary

Problems solved by technology

[0003] The research and construction of remote alarm technology for abnormal operation of distribution transformer equipment will greatly promote the safe and economical operation of distribution system equipment. Currently, distribution transformers in operation and below 400V distribution systems cannot be monitored in real time. There is a fault above, such as the fuse of the high and low voltage fuse of the transformer is blown, and the user has a power outage. Only the user who relies on the power outage notifies the maintenance personnel on duty to replace the fuse; such a long round-trip maintenance time affects the power supply to the user and reduces the reliability of the power supply. If the remote alarm technology for abnormal equipment operation in the distribution transformer station area can be fully promoted and applied, the power supply reliability of the distribution system will be greatly improved, and it will also promote the development of smart grid construction technology.
