Description

A kind of transformer station's electrical control cabinet noise and electromagnetic radiation monitoring shielding harness
Technical field
The present invention relates to electromagnetic field technology field, be specifically related to a kind of transformer station's electrical control cabinet noise and electromagnetic radiation prison Survey shielding harness.
Background technology
Electrical control cabinet is responsible for receiving the electric information of each device in transformer station and controlling, but electrical control cabinet is big Duo Shi collective is placed in control room, and noise and electromagnetic radiation are very big, along with development and people's ring of China's electric utility Protect the raising of consciousness, how to reduce even eliminating the sound pollution of electrical control cabinet and electromagnetic pollution has become as a new class Topic.Electrical control cabinet noise and electromagnetic radiation at present is administered and is relied primarily on increase screening arrangement.Screening arrangement is typically by special material Material is made, and can absorb a certain frequency spectrum or a certain frequency range pectrum noise, thus realize reducing the purpose that whole device makes a noise. But some noise shielding devices itself have defect, such as: 1, the noise spectrum narrow range absorbed, shield effectiveness is caused to fail to understand Aobvious;2, affect ventilation and the heat radiation of switch board device, electromagnetic radiation is controlled to reduce the injury to staff and does not the most do Method, can only be placed on switch board in completely cutting off the room radiated and forbid that non-working person is close, but enters work for needs For the personnel made, during electromagnetism injury, it is engraved in continuation.
Current ELECTROMAGNETIC RADIATION SHIELDING and noise reduction use thin coating at electrical control cubicles external coating and automatically controlled mostly Room wall design adds noise radiation shielding construction, and the former effect of shielding is unsatisfactory, and indoor staff is not had by the latter Protected, it is under electromagnetic noise environment the biggest to actual bodily harm for a long time.And use thicker absorbing material or seal cabinet pair Electrical control cubicles carries out radiation shield, the most totally unfavorable to its heat radiation, is easily damaged equipment.And prior art does not has in control room The intensity of electromagnetic radiation is monitored, it is impossible to staff's reference information, it is impossible to grasp the electromagnetic radiation feelings in control room Condition, when occurring that electromagnetic radiation intensity is excessive, staff can not excavate, and long-term place is totally unfavorable to health in the present context.
A kind of electromagnetic shielding chamber of the disclosure of the invention of Application No. 201410490514.X.This electromagnetic shielding chamber includes: screen Cover housing;The inside of this shield shell surrounds an airtight electromagnetic shielding space, and its wall from-inner-to-outer includes: permalloy screen Cover interlayer, supporting layer, aluminium sheet shielding interlayer, permalloy shielding interlayer and aluminium sheet shielding interlayer and be separately fixed at the interior of supporting layer Side and outside.The present invention not merely uses permalloy to shield low frequency magnetic field, also uses aluminium sheet to carry out high-frequency electromagnetic field shield, from And improve radioshielding effect.But this invention can not carry out electromagnetic shielding to each electrical control cabinet, it is impossible to ensure indoor Healthy in staff.
The disclosure of the invention of Application No. 201510820315.5 a kind of communication base station electrical control cabinet noise and electromagnetism spoke Penetrating monitoring screening arrangement, including switch board and housing, described housing is three-decker, includes corrosion resistant plate, foamed aluminium board successively With wedge shape absorbing material plate, described shell inner surface arranges temperature-humidity monitoring module, and described housing outer surface arranges noise prison Surveying module and electromagnetic radiation monitoring module, described enclosure interior arranges temperature control module.The present invention uses spliting type absorbing material plate Radiation-screening, is much larger than radiation shielding coating of the prior art to the assimilation effect of radiation;Use foamed aluminium board that noise is carried out Absorb, and radiation can further be cut down, the noise that equipment runs can be eliminated as far as possible;Warm and humid in switch board Degree is monitored and arranges the adjustment module of humiture, it is to avoid housing is thicker causes switch board heat radiation inconvenience, improves equipment fortune The safety of row, extends the service life of equipment.This invention does not sets up a perfect electromagnetic environment monitoring system, and for The temperature control effect of electrical control cabinet is poor, and energy consumption is relatively big and the most intelligent.
Summary of the invention
Problem to be solved by this invention is to provide a kind of transformer station's electrical control cabinet noise and electromagnetic radiation monitoring shielding System, uses the switch board sealed to shield internal electromagnetic radiation and noise, reduces the impact in control room, and will Map in control room combines with noise and the radiation event of monitoring, reminds for Field Force.
