Intelligent instrument based on Internet of things for power distribution station

Abstract

The invention relates to an intelligent instrument based on the Internet of things for a power distribution station. The intelligent instrument comprises a display panel and a casing, wherein the display panel is provided with a display screen, a first protection mechanism, a second protection mechanism and multiple operation buttons, the first protection mechanism comprises a first baffle board, a rotation unit and a fixing assembly, the second protection mechanism comprises a lifting rod, a second baffle board, multiple second insertion rods and multiple insertion rings, two sides of the casing are provided with concave ports, and the concave ports are internally provided with fastening mechanisms. According to the intelligent instrument, a second clamping board is driven through the fastening mechanisms to rotate to make the first clamping board and the second clamping board to carry out fastening mounting from front and back surfaces of an opening of a power distribution cabinet, not only can the instrument be guaranteed to safely mount on the power distribution cabinet, but also the display screen and the operation buttons are respectively protected through the first protection mechanism and the second protection mechanism, the display screen can be prevented from being broken because of extrusion, so error setting of instrument parameters caused by equipment damage and error touch on the operation buttons can be avoided, and equipment practicality is improved.

Description

technical field [0001] The invention relates to the field of smart meters, in particular to a smart meter for power distribution stations based on the Internet of Things. Background technique [0002] Intelligent instrument, also known as intelligent electromagnetic flowmeter, adopts the world's advanced technology and uses constant current and low frequency three-valued rectangular wave excitation, which not only has the advantages of rectangular wave magnetic field, but also overcomes the shortcomings of sine wave magnetic field; it can also eliminate power supply voltage fluctuations, Errors caused by power frequency changes and excitation coil impedance changes; and have excellent zero point stability and are not affected by fluid noise interference, so they have the characteristics of high stability and high reliability. [0003] Since the smart meter can accurately measure the function of each parameter in the electricity, the smart meter is often used in conjunction w...

Problems solved by technology

[0003] Since the smart meter can accurately measure the function of each parameter in the electricity, the smart meter is often used in conjunction with various power distribution cabinets for power distribution stations. In the power distribution cabinet, it is used to connect various signal lines. In order to fix the smart meter On the power distribution cabinet, it is usually necessary to drill a hole on the cabinet door of the power distribution cabinet, then insert the meter into the hole, and insert the fixing bracket from the gap between the two sides of the meter and the hole, but because the gap between the meter and the hole is small It is very small, which makes it very laborious to insert the fixed bracket, and if you do not pay attention, the bracket will be damaged due to excessive force. Not only that, the display screen and operation buttons of the smart meter are usually directly exposed to the outside, causing the meter to be damaged during transportation and use. The display screen is damaged by extrusion, and the control buttons will also cause various electrical parameters to be incorrectly set inside the meter due to touch, making the meter measurement inaccurate
