Description
Technical field
The present invention relates to power switch cabinet electromagnetic field technology fields, and in particular to a kind of power switch cabinet static contact temperature prison
Survey method.
Background technique
With the update of power equipment, current most power plant, substation use the power delivery mode of switchgear, by
The actual temperature for the high pressure static contact that cannot be opened, therefore be unable to measure in running switchgear in operation in switchgear with
Current information.Switchgear longtime running is under complex environment, and internal high pressure static contact is easily loosened, aoxidized, in excess load
Run, install it is bad when, contact surface resistance can become larger, when load current flows through, high pressure static contact temperature
Can increase, even burn, cause large-area power-cuts, there is very big security risk, thus to the high pressure static contact in switchgear into
The cooling of row real-time monitoring is and its important with current information.But existing high pressure static contact temperature measuring equipment there is: operation
Complexity, safety is poor, and measurement is not accurate enough, quick, can not obtain measurement data in real time, measurement type is single, is only used for surveying
The problems such as amount temperature information.
Of the existing technology in order to solve the problems, such as, people have carried out long-term exploration, propose miscellaneous solution
Scheme.For example, Chinese patent literature disclose a kind of high-voltage switch contact temperature measuring equipment [application number:
201220002375.8], including the current transformer being sleeved on static contact of high-voltage switch support arm, the shell of current transformer
On wireless transmitter module by current transformer power supply is installed, be additionally provided with thermometer hole on support arm, be fitted in thermometer hole and nothing
The temperature sensor of line transmitting module input terminal electrical connection further includes that can receive wireless transmitter module to issue wirelessly connecing for signal
Module is received, the output end of wireless receiving module and the input terminal of controller are electrically connected, and the output end of controller is electrically connected with display
Screen.
Above scheme solves that existing high-voltage switch contact temperature measuring equipment is complicated for operation, safety is poor to a certain extent
The problem of, can be quickly obtained metrical information, but the program still remains: structure is complicated, and measurement accuracy is low, surveys
The problem of it is single to measure type, is only used for measurement temperature information.
Cabinet is responsible for that the electric information of device each in substation is received and controlled, but cabinet is big
It is mostly that collective is placed in control room, and noise and electromagnetic radiation are very big, development and people's ring with China's electric utility
How the raising for protecting consciousness, reduce the noise pollution for even being eliminated cabinet and electromagnetic pollution have become a new class
Topic.Cabinet noise and electromagnetic radiation improvement rely primarily on increase screening arrangement at present.Screening arrangement is generally by special material
Material is made, and can absorb a certain frequency spectrum or a certain frequency range pectrum noise, so that realizing reduces 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 causes shield effectiveness unknown
It is aobvious；2, the ventilation and heat dissipation for influencing control box arrangement reduce electromagnetic radiation control and do not yet to the injury of staff
Switchgear can only be placed in the room of isolation radiation and forbid non-working person close by method, but for needing to enter work
For the personnel of work, the electromagnetism injury moment is continuing.
Current ELECTROMAGNETIC RADIATION SHIELDING and noise reduction mostly uses greatly thin coating in power control cabinet external coating and automatically controlled
Noise radiation shielding construction is added in wall design in room, the former shields, and the effect is unsatisfactory, and the latter does not have indoor staff
There is protection, is in for a long time very big to actual bodily harm under electromagnetic noise environment.And use thicker absorbing material or sealing cabinet body pair
Power control cabinet carries out radiation shield, radiates and totally unfavorable to it, is easily damaged equipment.And do not have in control room in the prior art
The intensity of electromagnetic radiation is monitored, staff's reference information cannot be given, the indoor electromagnetic radiation feelings of control can not be grasped
Condition, when occur electromagnetic radiation intensity it is excessive when staff cannot excavate, long-term place is totally unfavorable to body in the present context.
Application No. is a kind of electromagnetic shielding chambers of the disclosure of the invention of 201410490514.X.The electromagnetic shielding chamber includes: screen
Cover shell；The inside of the shield shell surrounds a closed electromagnetic shielding space, and wall surface from-inner-to-outer includes: permalloy screen
Interlayer, supporting layer, aluminium sheet shielding interlayer are covered, permalloy shielding interlayer and aluminium sheet shielding interlayer are 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 carries out electromagnetic field of high frequency shielding using aluminium sheet, from
And improve radioshielding effect.But the invention cannot be electromagnetically shielded each cabinet, it cannot be guaranteed that indoor
Health in staff.
Application No. is a kind of communication base station cabinet noise of 201510820315.5 disclosure of the invention and electromagnetism spokes
Monitoring screening arrangement, including switchgear and shell are penetrated, it successively includes stainless steel plate, foamed aluminium board that the shell, which is three-decker,
With wedge shape absorbing material plate, temperature-humidity monitoring module is arranged in the shell inner surface, and the housing outer surface setting noise is supervised
Module and electromagnetic radiation monitoring module are surveyed, temperature control module is arranged in the enclosure interior.The present invention uses spliting type absorbing material plate
Radiation-screening is much larger than radiation shielding coating in the prior art to the assimilation effect of radiation；Noise is carried out using foamed aluminium board
It absorbs, and radiation energy is further cut down, the noise that equipment is run can be eliminated as far as possible；To warm and humid in switchgear
Degree is monitored and is arranged the adjustment module of temperature and humidity, avoids shell is thicker from causing to switch cabinet heat radiation inconvenience, improves equipment fortune
Capable safety extends the service life of equipment.The invention does not set up a perfect electromagnetic environment monitoring system, and for
The temperature control effect of cabinet is poor, and energy consumption is larger, and not intelligent.
