Abstract
The utility model relates to an electric power system's power supply unit, specifically speaking are a power transformer's noise and electromagnetic radiation shield assembly, its characterized in that is equipped with the frame, acoustic celotex board and electromagnetic shield board, the periphery of acoustic celotex board and electromagnetic shield board is inlayed in the frame on stack ground in front and back respectively, the lower extreme of frame is equipped with the support frame, the acoustic celotex board in frame and the frame and the upper end of electromagnetic shield board are to the curved curved of front upper place arc, in using, also be exactly acoustic celotex board board orientation and press close to the transformer as far as possible the preceding of this device, then through the ground screw, the frame is fixed to the support frame can, the acoustic celotex board absorbs the noise of transformer, flat steel platform introduces the earth with the electromagnetism that the transformer produced through the earth connection, it dismantles portably to have the installation, good utilization effect, repeatable use.
Description
Technical field
The present invention relates to the power supply unit of power system, the noise of a kind of power transformer and electromagnetic radiation shielding device.
Background technology
It is known that, the continuous quickening of urban construction, land resource day is becoming tight, the thing followed is that the plot ratio of newly-built residential quarter is continuously increased, increasing of resident's quantity, power consumption increases, need to be equipped with more transformator, and some transformers is close to residential building, although transformator produced noise and electromagnetic radiation value in day-to-day operation all meet national standard, but small part resident house is because of nearer away from transformator, in the quiet environment such as night, still can hear slight noise, affect resident to have a rest, by transformer noise, complaint and dispute in terms of electromagnetic radiation get more and more.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, it is provided that a kind of installing/dismounting power transformer noise easy, reusable and electromagnetic radiation shielding device.
This utility model can be reached by following measure:
A kind of power transformer noise and electromagnetic radiation shielding device, it is characterized in that being provided with framework, baffle and electromagnetic shielding plate, the periphery of baffle and electromagnetic shielding plate is front and back embedded in framework to superposition respectively, it is that forward upward curved bend is curved that the lower end of framework is provided with the upper end of the baffle in bracing frame, framework and framework and electromagnetic shielding plate.
Baffle thickness described in the utility model is not less than 5mm, and electromagnetic shielding plate is that the spacing of smooth plane steel plate, baffle and electromagnetic shielding plate is not less than 10 mm, to improve the ability of sound insulation and anti-electromagnetic radiation.
The bottom of electromagnetic shielding plate described in the utility model or framework is provided with earthing screw, earth lead one end is connected with ground earthing screw, the other end is connected with Pseudobulbus Bletillae (Rhizoma Bletillae), described Pseudobulbus Bletillae (Rhizoma Bletillae) is provided with screw mandrel, the leading section of screw mandrel is tip-angled shape, and the rearward end of screw mandrel is provided with on screw thread, clamp nut and back of the body nut line screw thread respectively in the rear end of screw mandrel, earth lead is through the clamp nut clamping of back of the body nut, and screw mandrel is provided with helical blade.
Bracing frame lower end described in the utility model is provided with through hole, is provided with Pseudobulbus Bletillae (Rhizoma Bletillae) in through hole, to increase the stability of bracing frame.
When this utility model uses, by before this device namely baffle plate towards and press close to transformator as much as possible, then through Pseudobulbus Bletillae (Rhizoma Bletillae), bracing frame, framework is fixed, baffle absorbs the noise of transformator, the grounded line of electromagnetism that transformator is produced by plane steel plate introduces the earth, has the advantages such as installing/dismounting is easy, using effect is good, reusable.
