The utility model relates to an optical fiber lead-out structure of an intelligent transformer, which comprises an outer support bar, an oil channel cushion block, a through plate and a through plate. It is connected with the penetrator through bolts, and also includes a sealing gasket. The oil passage pad is obliquely provided with a positioning slot, and the inner contour of the positioning slot matches the shape and structure of the optical fiber probe; the outer support bar is provided with The lead-out groove matched with the optical fiber; the optical fiber is led out to the outside of the through-disc through the feeder, and a sealing gasket is provided at the bolt connection between the feed-through and the feed-through disc. The advantages are: the position of the optical fiber probe is limited by the positioning card slot to prevent the optical fiber probe from moving; the lead-out groove set on the outer support can play the role of positioning the optical fiber to prevent the optical fiber from shaking randomly and blocking the oil passage; the thread of the through device and the through plate A gasket is added at the connection to prevent the transformer oil from contacting the thread, thereby avoiding oil leakage at the thread.
Description
Technical field
This utility model is related to a kind of optical fiber lead-out structure of intelligent transformer.
Background technology
At present, the fibre-optical probe used in intelligent transformer is direct, real-time measuring transformer coil temperature has become current
Current metering system.Which needs fibre-optical probe is placed in transformer coil, and in prior art, fibre-optical probe is in device body
It is interior to there is the unstable defect of positioning.Meanwhile, the through device that optical fiber is drawn with insertion disk using being threadedly coupled, deposit by the connected mode
In the shortcoming of permeability.
The content of the invention
To overcome the deficiencies in the prior art, the purpose of this utility model to be to provide a kind of optical fiber of intelligent transformer and draw knot
Structure, fibre-optical probe are difficult for drop-off, reduce outer fiber abrasion, improve service life；Prevent the generation of permeability phenomenon.
For achieving the above object, this utility model is achieved through the following technical solutions：
A kind of optical fiber lead-out structure of intelligent transformer, including outer stay, oil channel cushion block, insertion disk, through device, oil duct pad
Block is arranged in transformer coil, and outer stay is arranged on outside transformer coil, and insertion disk is connected by bolt with through device, also
It is including sealing gasket, oblique on described oil channel cushion block to be provided with locating groove, locating groove Internal periphery and fibre-optical probe contour structures
Match；The outer stay is provided with the lead-out groove matched with optical fiber；Optical fiber is drawn out to outside insertion disk by through device, is passed through
Sealing gasket is provided with logical device and the bolt connection of insertion disk.
Described extraction well width is less than fiber outer diameter.
Described insertion disk is provided with seal groove, seal groove and arranges sealing gasket.
Compared with prior art, the beneficial effects of the utility model are：
Fibre-optical probe position is limited by locating groove, fibre-optical probe play is prevented；The lead-out groove arranged on outer stay can
Play a part of to position optical fiber, prevent optical fiber from arbitrarily rocking, block oil duct；Through device increases close with the threaded connection place of insertion disk
Packing, makes transformer oil touch screw thread, so as to avoid permeability at screw thread.

Specific embodiment
This utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Enforcement is not limited to following embodiment.
A kind of optical fiber lead-out structure of intelligent transformer, including outer stay 4, oil channel cushion block 6, insertion disk 1, through device 2, oil
Road cushion block 6 is arranged in transformer coil, and outer stay 4 is arranged on outside transformer coil, and insertion disk 1 passes through bolt with through device 2
It is connected, it is also including sealing gasket 3, oblique on oil channel cushion block 6 to be provided with locating groove 7, see Fig. 1,7 Internal periphery of locating groove and optical fiber
Probe contour structures match；The outer stay 4 is provided with the lead-out groove 5 matched with optical fiber, sees Fig. 2, Fig. 3；Optical fiber passes through
Through device 2 is drawn out to outside insertion disk 1, is provided with sealing gasket 3, sees Fig. 4, Fig. 5 at through device 2 and the bolt connection of insertion disk 1.
Wherein, 5 width of lead-out groove is less than fiber outer diameter.Insertion disk 1 is provided with seal groove, seal groove and arranges sealing gasket
3。
Embodiment
Oil channel cushion block 6 in transformer coil opens oblique locating groove 7, and coil outer stay 4 is opened axial lead groove 5, passed through
Overall 1 opens seal groove, and insertion disk 1 is connected using sealing gasket 3 with through device 2.
As optical fiber is 3.1mm in inside transformer section diameter, in oil channel cushion block 6 of the thickness for 3mm, light is made
Fine temperature-sensing probe can completely attach to coil, the actual temperature of measuring coil.
After optical fiber is drawn in oil channel cushion block 6, circle along the shaft is needed to leading to outside coil, therefore in the outer stay of coil
The groove of 3mm is opened on 4, optical fiber is embedded in groove, prevent optical fiber from arbitrarily rocking, block oil duct.
Optical fiber is fixed on insertion disk 1 by through device 2, and through device 2 increases sealing gasket with the threaded connection place of insertion disk 1
3, make transformer oil touch screw thread, so as to avoid permeability at screw thread.
