Remote alarm device used in high voltage phase loss of distribution transformer

Abstract

The invention discloses a remote alarm device used in the high voltage phase loss of distribution transformer. The remote alarm device comprises a signal acquiring circuit, a signal judging circuit and an alarm communication circuit, wherein the signal acquiring circuit is output and connected with the signal judging circuit; the signal judging circuit is output and connected with the alarm communication circuit; the alarm communication circuit is connected with a distribution network intelligent control center or connected to a mobile phone of an electrician; and in case of high-voltage power loss during running of the distribution transformer, the signal acquiring circuit acquires a phase loss signal of the high-voltage power supply and immediately sends the phase loss signal to an alarm transmitting circuit for remote alarm, and after receiving the alarm, an electrician on duty immediately arrives at the site to handle accidents. By applying an advanced electronic technology, the remote alarm device has the advantages that: accident handling time is shortened, power supply volume is increased, enterprise profit and social profit are increased; moreover, the remote alarm device has great significance for promoting the development of intelligentized technology of distribution systems.

Description

technical field [0001] The invention relates to a remote alarm technology for high-voltage power supply phase loss during the operation of a distribution transformer, which is a remote alarm technology applied to high-voltage fuse melt blown or other reasons for high-voltage phase failure during the operation of a power supply transformer in a distribution network. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, the unprecedented development of the power industry, and the rapid development of the national power grid construction. Electricity is transformed by distribution transformers and sent to thousands of households.

Problems solved by technology

Electricity is transformed by distribution transformers and sent to thousands of households. The current operating distribution transformers are basically out of order because they cannot be monitored in real time. The user will notify the maintenance personnel to carry out equipment maintenance, which will delay the time for troubleshooting. long, which has a great impact on users' power outages, so the reliability of power supply is low, and the equipment damage rate is high, which cannot meet the requirements of the continuous improvement of people's living standards. When the time comes, the maintenance personnel will go to the scene to carry out emergency repairs in time, shorten the time for handling accidents, increase the power supply, and increase the benefits of the enterprise and society
