Romote intelligent type transformer

Abstract

The invention relates to a remote intelligent transformer, and the main characters: in the low-voltage place of the side or top part of the transformer, there is an intelligent box arranged, the outside of the box is configured with a lock controlled switch, the inside of the box is provided with an AC contactor, a current mutual inductor, a control integrated module, a display and an electronic electric energy meter, where the AC contactor is connected with the low-voltage outlet end of the transformer, the current mutual inductor is connected with the inlet ends of the integrated control module and the electronic electric energy meter by each phase output line of the transformer, the display is connected with the integrated control module, and a meter-reading device in the integrated control module controls the contacts of a relay to control the output, connectes with the electronic electric energy meter butt to butt through a RS-485 interface, and remotely communicates through a GSM public communication network. It can implement the intelligent control of used electricity quantity data of a remote transformer, like automatic monitoring, automatic alarm, automatic protecting, remote measuring, remote meter reading, etc.

Description

Technical field: [0001] The invention belongs to the technical field of power transformers, and is a remote intelligent transformer. Background technique: [0002] In the known technology, the traditional power transformer can only realize the function of converting high voltage to low voltage, but when the transformer is working, it cannot detect the change of voltage and current during the operation of the transformer, especially when the transformer is overloaded. It is impossible to cut off and adjust, so that the transformer can only be overloaded. After a certain limit, it is easy to cause damage to the transformer, affect the normal power supply, and may burn the user's electrical equipment. Secondly, the power transformer does not have any alarm and communication functions, and cannot rush to the scene to solve it in time when there is a fault or power theft, resulting in a long-term power outage or the situation that equipment and power have been stolen. In additio...

[0002] In the known technology, the traditional power transformer can only realize the function of converting high voltage to low voltage, but when the transformer is working, it cannot detect the change of voltage and current during the operation of the transformer, especially when the transformer is overloaded. It is impossible to cut off and adjust, so that the transformer can only be overloaded. After a certain limit, it is easy to cause damage to the transformer, affect the normal power supply, and may burn the user's electrical equipment

Secondly, the power transformer does not have any alarm and communication functions, and cannot rush to the scene to solve it in time when there is a fault or power theft, resulting in a long-term power outage or the situation that equipment and power have been stolen

In addition, the watt-hour meter is installed on the transformer, and the management personnel can only go to the site to read the meter regularly, which increases the labor intensity of the personnel.
