As shown in fig. 1 and fig. 2, the closing coil fixing device of the outdoor vacuum circuit breaker provided by this embodiment includes: connecting plate 3, locking structure 4, threaded rod 5 and fastening nut 6.
The connection plate 3 is placed on the mounting plate 2 of the vacuum circuit breaker and the threaded rod 5 is passed through both the mounting plate 2 and the connection plate 3 and tightened by means of a tightening nut 6. The locking structure 4 comprises a locking plate 41, a U-shaped clamp 42 and a locking bolt 43; the locking plate 41 is arranged on the connecting plate 3, the closing coil shell 1 abuts against the connecting plate 3, the connecting plate 3 and the closing coil shell 1 extend into the U-shaped groove 46 of the U-shaped clamp 42, and the locking plate 41, the U-shaped clamp 42 and the closing coil shell 1 are locked and fixed through the locking bolt 43.
The shell 1 of the closing coil is locked and fixed on the connecting plate 3 through a locking structure 4, the connecting plate 3 is fastened on the mounting plate 2 of the vacuum circuit breaker through a threaded rod 5 and a fastening nut 6, namely, the closing coil is fastened on the mounting plate 2 through a fixing device. The existing circuit breaker manufactured by manufacturers has a mechanism-frame integrated structure, the layout of parts is compact, the number of parts of an operating mechanism is large, a circuit board and an auxiliary contact of a secondary circuit are fully distributed in the space between every two partitions of the circuit breaker, a closing coil is taken out for replacement, all bolts and shielding objects for fixing the closing coil need to be removed, after the coil is replaced, the parts need to be restored, the replacement coil is used for about 1.5 hours on average, at least 3-4 field workers are matched, and the power failure time is long. After setting up fixing device, when overhauing it and dismantling, directly with fixing device from mounting panel 2 dismantlement can, compare in dismantling closing coil, dismantle fixing device simpler, its reduction that can bigger degree is to the dismantlement of other parts, the simplification flow, raises the efficiency.
As shown in fig. 1 and 2, one end of the locking bolt 43 passes through a side wall of the U-shaped clamp 42 close to the locking plate 41 and abuts against the locking plate 41, and a threaded hole 44 matched with the locking bolt 43 is formed in the side wall of the U-shaped clamp 42. Meanwhile, a locking groove 45 into which the locking bolt 43 is inserted is provided on the locking plate 41, and the locking groove 45 does not penetrate the locking plate 41. When the locking bolt 43 is fastened, under the matching action of the locking bolt 43 and the threaded hole 44, the U-shaped clamp 42 can bring the closing coil housing 1 to press against the locking plate 41, so that the purpose of fastening the closing coil is achieved. In the structure, the locking plate 41 is attached to the closing coil shell 1, so that a better fastening effect is achieved, the height of the locking plate 41 can be kept equal to that of the closing coil shell 1, the U-shaped clamp 42 can be conveniently clamped from top to bottom, the width of the U-shaped groove 46 of the U-shaped clamp 42 is slightly wider than the sum of the thickness of the side wall of the closing coil shell 1 and the thickness of the locking plate 41, and the fastening operation is facilitated. In other schemes, the U-shaped clamp 42 can clamp the whole closing coil housing 1 in a clamping manner, and the purpose of locking can also be achieved.
The locking groove 45 has a limiting effect, and the locking bolt 43 cannot abut against the closing coil housing 1 during locking, so that the locking bolt 43 is prevented from penetrating through the locking groove 45 to act on the closing coil housing 1 to damage the housing when the locking bolt 43 is screwed down vigorously to lock the housing.
The locking plate 41, the U-shaped clamp 42 and the closing coil shell 1 are locked and fixed through a plurality of locking bolts 43, and a plurality of corresponding locking grooves 45 are formed; in this embodiment, two locking bolts 43 and corresponding locking grooves 45 are provided, so that the locking effect is more uniform and stable.
On the other hand, in this embodiment, the locking plate 41 is vertically disposed on the connecting plate 3, and according to different requirements, the locking plate 41 may also be disposed on the connecting plate 3 at other angles, so as to meet the installation requirements of different angles of the closing coil. Meanwhile, the U-shaped card 42 can be used for clamping the card from other angles, and the scheme is flexible and practical. Further, the locking plate 41 may be rotatably or movably disposed on the connecting plate 3, which may be adjusted according to actual requirements.
A bottom plate 31 is arranged on the connecting plate 3, and the bottom plate 31 is positioned below the closing coil shell 1 and supported and abutted against the bottom of the closing coil shell 1; the height of the bottom plate 31 can be set according to the height requirement of the closing coil, and the bottom plate 31 and the connecting plate 3 can be integrally formed. When the closing coil is locked on the connecting plate 3, the bottom plate 31 has a supporting function, and is convenient to mount and fasten.
As shown in fig. 1 and 2, two fastening nuts 6 are fittingly mounted at one end of the threaded rod 5 near the connecting plate 3; aim at, when locking, laminating between two fastening nut 6, locking each other avoids leading to becoming flexible between connecting plate 3 and the mounting panel 2 because mechanism shakes. In addition, when installing connecting plate 3 on mounting panel 2, when fastening nut 6 was for screwing up the fastening, connecting plate 3 can rotate for the pivot by threaded rod 5, and simultaneously, threaded rod 5 is installed in the one end that connecting plate 3 is close to the mounting panel 2 outside, like this, can be with the combined floodgate coil on connecting plate 3 switching in or the mounting panel 2 of roll-out, convenient maintenance dismantlement and installation, simple structure, the operation is also convenient.
In the actual installation, connecting plate 3 is the sheet structure that laminating mounting panel 2 set up generally, and operating space is little, when rotating or taking off connecting plate 3, does not well get the strength of hand. At this time, a power-assisted rod 7 can be arranged on the connecting plate 3, and the connecting plate 3 can be moved or rotated by applying force to the power-assisted rod 7, so that the labor is saved and the convenience is also realized.
In this embodiment, the other scheme is used, helping hand pole 7 one end is rotated and is installed in the one end that connecting plate 3 is close to the mounting panel 2 outside, is equipped with a stopper 8 that restricts helping hand pole 7 rotation range on the connecting plate 3. The limiting block 8 is arranged at the edge of the connecting plate 3 close to the outer side of the mounting plate 2, and after the connecting plate 3 rotates to abut against the limiting block 8, force is continuously applied, so that the connecting plate 3 can be rotated to be loosened from the mounting plate 2, and the connecting plate 3 is convenient to detach; meanwhile, the force arm is lengthened by using the power-assisted rod 7, and the power-assisted bicycle has a good labor-saving effect.
Meanwhile, a positioning hole 32 is formed in the connecting plate 3, one end of a positioning rod penetrates through the positioning hole 32 to be inserted into or penetrate through the mounting plate 2, and the positioning rod and the threaded rod 5 act together, so that a good positioning and fastening effect is achieved, and the connecting plate 3 is safely and stably mounted on the mounting plate 2; of course, the locking mode of the positioning hole 32 also uses the threaded rod 5, and the same effect and purpose can be achieved.
This device simple structure, the simple operation, convenient to detach can guarantee again the firm of combined floodgate coil installation, improves combined floodgate coil and overhauls or change efficiency, labour saving and time saving.
