Description
Technical Field
The utility model relates to a power electronic technology field, more specifically say so and relate to a fixed knot constructs is got in bundling current induction.
Background
The power monitoring system is a key component of the whole smart power grid, accounts for more than 40%, at present, power supply of equipment in online monitoring of a power transmission line is always a relatively troublesome problem, photovoltaic power taking is adopted under the conventional condition, but the power taking mode is very easily influenced by the external environment, particularly in winter, the power taking capacity of the power supply can be greatly reduced in cloudy and snowy days for a long time, and large manpower and maintenance cost are generated.
And CT gets electricity (current induction gets electricity), utilizes the CT of installing on the power line to obtain the electric energy through the electromagnetic induction principle, for the equipment power supply, simple to operate. CT is got the electricity and is mostly adopted open-close type structure, gets the electricity iron core and adopts the annular bisection to install in plastic casing basically, and the iron core size needs to change according to shell structure, because of the power transmission cable diameter thickness differs, varies from 10mm to 150mm, if uses plastic casing, needs to open many moulds, increases the cost, and the site operation is also very inconvenient, needs survey the cable diameter size in earlier stage, and the installation needs to take many specifications product, and is inefficient. In the existing electric power work, the iron core is fixed through the electricity taking fixing piece, but the iron core is fixed through the straight fixing piece, the locking screw directly acts on the iron core, the contact area of the iron core is small, the magnetic resistance is large, the magnetic conductivity is reduced, and the electricity taking capability is weak.
SUMMERY OF THE UTILITY MODEL
To the weak point of above-mentioned prior art, the utility model provides a fixed knot constructs is got in bundling current-induction for solve above-mentioned technical problem.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a fixed knot constructs is got in bundling current induction, includes banded iron core, arc mounting and fastening screw, banded iron core is equipped with the coil, the arc mounting is equipped with interior clamp plate and supplies the arc passageway that banded iron core passed, fastening screw with arc mounting threaded connection, fastening screw with interior clamp plate butt.
Preferably, the inner pressure plate is slidably connected with the inner wall of the arc-shaped channel.
Preferably, the arc length of the inner pressure plate is 6.0-9.0 mm.
Preferably, the thickness of the arc-shaped channel is more than 2 times of the thickness of the band-shaped iron core.
The utility model has the advantages that:
1) the strip-shaped iron core tightly surrounds the cable and is fixed through the arc-shaped fixing piece, so that the strip-shaped iron core can adapt to the specifications of cables with different diameters, and the convenience of operation is improved;
2) the interior clamp plate of arc mounting compresses tightly the banded iron core in the arc passageway, compares with fastening screw direct compression banded iron core, and interior clamp plate area is big, and the roughness is high, and the clearance of banded iron core and cable after compressing tightly is little, increases the effective sectional area of iron core, improves and gets the electric capacity.
