A distribution automation monitoring terminal

Abstract

The invention provides a power distribution automation monitor terminal. The power distribution automation monitor terminal comprises a photosensitive resistor, a storage battery, an electromagnetic valve, a temperature controlled switch, a fan, an arc probe, an A / D (analog / digital) converter and a single chip microcomputer, wherein the photosensitive resistor is connected with the storage battery through wires, and the electromagnetic valve is connected with the photosensitive resistor through wires, so that the problem of incapability of in a short time putting out fire caused by short circuit of a power distribution monitor terminal can be solved; the temperature controlled switch is connected with the storage battery through wires, and the fan is connected with the temperature controlled switch through wires, so that the problem of poor heat dissipating property of the power distribution monitor terminal can be solved; the arc probe is connected with the A / D converter through data lines, and the A / D converter is connected with the single chip microcomputer through data lines, so that the problem that internal faults of the power distribution monitor terminal cannot be found timely can be solved. The power distribution automation monitor terminal is reasonable in design, simple in structure, high in security, good in stability and low in operation risks.

Description

technical field [0001] The invention relates to a power distribution automation monitoring terminal, which belongs to the field of power distribution equipment. Background technique [0002] The distribution automation monitoring terminal is a distribution monitoring terminal integrating monitoring, metering, power quality, remote communication, local communication and other functions. It is suitable for the operation monitoring of public transformers and distribution lines. The link in the power system that is directly connected to the user and distributes electric energy to the user. [0003] In the prior art, in the power system, the grid power first enters the user from the high-voltage transmission line of the power supply company. In the middle process, a special distribution transformer, referred to as a distribution transformer, is required to realize the conversion from high voltage to low voltage. The electric transformer plays the role of undertaking the high-vol...

Problems solved by technology

Since the power distribution places are relatively scattered and most of them are in the outdoor environment, it has caused certain difficulties in its maintenance and safety. Usually, the power distribution places in the station area cannot be effectively protected and isolated, which will cause danger and Unconventional operations cannot be detected and recorded in time. Generally, the insulator will age after long-term operation, which is very easy to cause short circuits and fires. The heat emitted by the equipment in the terminal cannot be effectively dissipated. At the same time, it is difficult for maintenance personnel to determine whether there is an arc inside when opening the power distribution terminal. Blindly opening it can easily cause personal injury. Therefore, an automatic monitoring terminal for power distribution is urgently needed to solve the appeal. The problem
