Description
Technical field
The invention belongs to reactor technical field more particularly to a kind of downfield dry-type air-core reactors.
Background technique
Existing dry-type air-core reactor is since its starting voltage is evenly distributed, the linearity is good, loss is small, low noise, installation
Conveniently, it safeguards the advantages that simple, is widely applied in the power system.But since dry-type air-core reactor is without closed magnetic
Circuit, so dry-type air-core reactor generates biggish magnetic field around it, leakage field is extremely serious, and has stronger penetrate
Power not only has an impact other electrical equipments around, and constitutes to occupational exposure potentially hazardous.
For dry air reactor leakage field problem, at present power department only by increase tour personnel and reactor away from
From to lower influence of the power frequency magnetic field to tour personnel's health, but due to being limited to the existing dry-type hollow electricity of substation's occupied area
Anti- device and tour channel distance are often relatively close, are making an inspection tour the ground power frequency magnetic field in channel commonly greater than national exposure limit standard
(i.e. 100 μ T).
To sum up, the power frequency magnetic field that existing dry-type air-core reactor generates is larger, and power frequency magnetic field is unsatisfactory for contact limitation mark
Standard becomes those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
The present invention provides a kind of downfield dry-type air-core reactor, solve what existing dry-type air-core reactor generated
The technical issues of power frequency magnetic field is larger, and power frequency magnetic field is unsatisfactory for contact limitation standard.
The present invention provides a kind of downfield dry-type air-core reactors, including air reactor, support cylinder and protection body;
The support cylinder is installed below the air reactor;
The protection body is installed on the support cylinder;
The distance between the protection body and the air reactor are 1m;
The protection body is aluminium disk or iron disk.
It preferably, further include supporting insulator;
The supporting insulator is arranged in the protection external surface.
Preferably, the radius of the protection body is 1m~1.8m.
Preferably, the protection body with a thickness of 5mm
Preferably, the protection body is aluminium disk.
Preferably, the radius of the protection body is 1.8m.
Downfield dry-type air-core reactor provided by the invention compared with the existing technology the advantages of are as follows:
1, the power frequency magnetic field intensity outside 2 meters of dry-type air-core reactor can be made to be lower than international Non-ionizing radiation committee member
Occupational exposure limit (i.e. 1000 μ T), the power frequency magnetic field intensity outside 3 meters is lower than national exposure limit standard (i.e. 100 μ T),
Protect inspection operating personnel health.
2, easy for installation, beauty is saved;
3, protection body is erected at below air reactor and is not take up floor area, does not influence polling path.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below

The distance between protection body 3 and air reactor 1 are 1m;
Protection body 3 is aluminium disk or iron disk.
Downfield dry-type air-core reactor provided in an embodiment of the present invention compared with the existing technology the advantages of are as follows:
1, the power frequency magnetic field intensity outside 2 meters of dry-type air-core reactor can be made to be lower than international Non-ionizing radiation committee member
Occupational exposure limit (i.e. 1000 μ T), the power frequency magnetic field intensity outside 3 meters is lower than national exposure limit standard (i.e. 100 μ T),
Protect inspection operating personnel health.
2, easy for installation, beauty is saved;
3, protection body is erected at below air reactor and is not take up floor area, does not influence polling path.
It further, further include supporting insulator 4;
Supporting insulator 4 is arranged in 3 outer surface of protection body.
Further, the radius of protection body 3 is 1m~1.8m.
Further, protection body 3 with a thickness of 5mm
