Embodiment Construction

[0019] Such as figure 1 As shown, the present invention includes a box body, and the above-mentioned box body includes a box door 1 , support plates 2 located on both sides of the box door 1 , and a bottom plate 3 perpendicular to the support plate 2 . Then, on the inside of the box body, that is, on the surfaces of the support plate 2 and the bottom plate 3 on both sides, a sound-absorbing material layer 101 is attached. The sound-absorbing material layer 101 is a three-dimensional grid structure system, and the aspect ratio L / D of the grid is at Between 20 and 30, that is, the aspect ratio of the grid can be any one of 20, 22, 25, 28, and 30.

[0020] A temperature sensor 102 and a humidity sensor 103 are arranged on the bottom plate 3, and the temperature signal and the humidity signal collected by the temperature sensor 102 and the humidity sensor 103 are respectively sent to the control system 104, and the control system 104 compares the received signal value with the pre...

Abstract

An intelligent low-voltage meter box comprises a box body. The box body comprises a box door, supporting plates and a bottom plate, wherein the supporting plates are positioned on two sides of the box door, and the bottom plate is arranged perpendicular to the supporting plates. Each of the supporting plates on two sides is provided with an arc slide way, a left pulley is arranged in the left arc slide way, a right pulley is arranged in the right arc slide way, the left pulley is connected with the right pulley through a round rod, the round rod is fixedly connected with a movable top cover and is further fixedly connected with a transmission rod, the left end of the transmission rod is hinged with a left connecting rod while the right end of the transmission rod is hinged with the right connecting rod, the left connecting rod and the right connecting rod are hinged with the supporting plates, a sound-absorbing material layer is arranged on the inner side of the box body and is a three-dimensional mesh structure system, and the length-diameter ratio of the mesh ranges from 20-30. By the technical scheme, after sound-absorbing materials are attached on the surface of the box body, noise is reduced greatly while the intelligent low-voltage meter box is good in use environment.

Description

technical field [0001] The invention relates to a measuring box for an electric energy meter, in particular to an intelligent low-voltage electric energy meter measuring box with low working noise. Background technique [0002] Generally speaking, the electric energy meter meter box of my country's electric power system is currently open design, and the electric energy meter junction box, joint junction box, and transformer are exposed when the meter box door is opened. According to many years of on-site discovery, this kind of open meter box is easy to steal electricity, such as: forging the lead seal to open the meter box, destroying the short circuit of the meter, replacing the nameplate twice, etc. This behavior increases the difficulty of the work for the managers , and increased the economic loss of the power sector. Contents of the invention [0003] The patent number is 200820148315, and the invention patent named "electric energy meter meter box with anti-theft f...
