Problems solved by technology

[0003] When the existing power meter is running, the internal electronic components work in a closed environment, which leads to the accumulation of heat generated by the operation, which makes the temperature inside the meter gradually increase. The electronic components work in a high temperature environment, which not only reduces the measurement of the meter Accuracy, while shortening the service life of the device, a small number of instruments will add heat dissipation holes, but after long-term operation, dust and impurities are easy to accumulate on the heat dissipation holes, resulting in blockage caused by poor air circulation, reducing heat dissipation efficiency, making existing power meters reduced availability of

Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0027] Such as figure 1 As shown, a power meter with good heat dissipation effect includes a main body 1 and two heat dissipation devices. The main body 1 is provided with a display screen 2 and several buttons 3. The main body 1 is provided with a PLC, and the display screen 2 and the button 3 are electrically connected to the PLC, and the two cooling devices are respectively located on both sides of the main body 1;

[0028] In the power meter, the display screen 2 on the main body 1 displays the power information, which is convenient for people to check and understand the operation status of the power grid. The parameters of the meter can be checked and se...

Abstract

The invention relates to a power instrument with good heat dissipation effect. The power instrument comprises a main body and two heat dissipating devices. Each heat dissipating device comprises a horizontal pipe, a vertical pipe and a gas conveying pipe, wherein a gas guiding mechanism is arranged in the horizontal pipe, a gas conveying mechanism is arranged in the gas conveying pipe, a dust suction mechanism is arranged in the vertical pipe, the dust suction mechanism comprises a rotating assembly, a connecting pipe, a rotating pipe, a branch pipe and a plurality of filter bags, and the gasconveying mechanism comprises a lifting assembly, a piston and two closing assemblies, each closing assembly comprises through holes, blocking blocks, pressing plates, springs, coils, horizontal plates and two vertical rods. The power instrument with good heat dissipation effect adsorbs dust in the air by means of the dust suction mechanism when the air flows in the vertical pipe, ensures that clear air enters the main body, achieves good heat dissipation effect, and conveys the gas into the connecting pipe by means of the gas conveying mechanism so as to blow air to the interior of the filterbags and blow off the dust, thereby realizing the continuous dust suction capability of the equipment, and improving the practicality of the equipment.
