Distribution transformer outlet connection point over-temperature alarm

Abstract

The present invention is an over-temperature alarm for the connection point of distribution transformer outlet, which includes a signal acquisition circuit, a signal judgment circuit, and an optical transceiver circuit; Connect the signal judging circuit and the optical transceiver circuit; the output of the signal judging circuit is connected to the optical transceiver circuit; the optical transceiver circuit is connected to the optical fiber communication cable and the electrical optical fiber communication cable circuit is connected to the intelligent control center of the distribution network; the present invention realizes on-line monitoring of the temperature at the junction of the outlet wire of the distribution transformer , intelligent alarm; the distribution network intelligent control center can also check the temperature value of the connection of each distribution transformer outlet wire. When the temperature of the distribution transformer outlet wire connection exceeds the specified value, the signal acquisition and judgment circuit will immediately transmit the over-temperature signal Provide remote alarm to the transmitting circuit of the optical transceiver, and the on-duty personnel will go to the scene to deal with the accident immediately after receiving the alarm, shorten the time for troubleshooting electrical equipment, reduce the damage rate of equipment, improve the reliability of power supply, and increase the benefits of enterprises and society.

Description

technical field [0001] The invention relates to a remote alarm technology for over-temperature at the connection points of the high and low outgoing wires of a distribution transformer, which is applied to a remote alarm for the over-temperature of the wire contact when the lead-out wires of the power supply transformer of the distribution network are running. 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. The power of the grid is transformed by the distribution transformer and sent to thousands of households. Since the distribution transformer currently in operation cannot be monitored in real time, it is basically caused by a heat failure at the connection of the transformer outlet wire and...

The power of the grid is transformed by the distribution transformer and sent to thousands of households. Since the distribution transformer currently in operation cannot be monitored in real time, it is basically caused by a heat failure at the connection of the transformer outlet wire and a power failure. The user will notify the maintenance personnel to carry out equipment maintenance. In this way, it takes a long time to deal with faults and has a great impact on power outages for users. Therefore, 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.
