Abstract
The utility model discloses a press nail device for a dry type transformer coil. The press nail device is characterized by comprising a press nail stand sleeve, a spring, a back-up ring, an adjusting column with outer threads, and a sleeve with inner threads, wherein the spring is arranged inside the press nail stand sleeve having a circular cavity, and the press nail stand sleeve having a circular cavity is positioned inside a cushion block having a circular cavity; the sleeve with inner threads sleeve and is connected, from top to bottom, the external diameter of the spring, and the adjusting column with outer threads is formed in a cavity of the upper end of the sleeve with inner threads and is pressed on the upper end of the spring; the circular cushion block is in fixed connection with a transformer coil; the sleeve with inner threads is fixedly connected via a clamping member to enable the clamping member and the transformer coil to be relatively fixed at a certain distance L; and different deformation forces can be produced by the spring and applied to the circular cushion block by adjusting positions of the adjusting column with outer threads in the sleeve with inner threads. The press nail device simple in structure and high in reliability has good manufacturability and universality, and can effectively minimize loosening of press nails.
Description
Technical field
The utility model relates to a kind of hold-down mechanism of dry-type transformer coil peculiar to vessel, especially relates to dry-type transformer coil nail pressing device.
Prior art
Along with the development of China's shipbuilding industry, the tonnage of ship is also in continuous increase, and the capacity of dry-type transformer peculiar to vessel is increasing, therefore, improves constantly for the requirement of the anti-short circuit capability of dry-type transformer peculiar to vessel.The nail pressing of current dry-type transformer coil peculiar to vessel is all that screw rod processing and fabricating forms, and coordinates nail pressing locking nut to carry out coil pressing, and it mainly relies on screw thread to tighten.Dry-type transformer peculiar to vessel has and waves and the shrinkage factor of insulating part, cushion block etc. in During Process of Long-term Operation, nail pressing is very easy to occur loosening, coil cannot be compressed and cause becoming flexible, thereby greatly reduce dry-type transformer anti-short circuit capability peculiar to vessel, in the time being short-circuited, can cause dry-type transformer coil peculiar to vessel to be burnt.
Summary of the invention
The defect that the utility model exists for current above-mentioned nail pressing, a kind of simple structure, high reliability is provided, and good manufacturability, highly versatile, can effectively reduce the loosening phenomenon of nail pressing, improve the anti-short circuit capability of dry-type transformer peculiar to vessel, guaranteed the dry-type transformer coil nail pressing device of dry-type transformer operational reliability peculiar to vessel.
In order to solve above-mentioned nail pressing defect, the utility model adopts following technical scheme: dry-type transformer coil nail pressing device, it is characterized in that: comprise nail pressing cover for seat, spring, back-up ring, with externally threaded adjustable column, be with female sleeve, it is in circular nail pressing cover for seat that its medi-spring is arranged at inner chamber, and inner chamber is that to be located in inner chamber be in circular cushion block to circular nail pressing cover for seat; Be with female sleeve to be socketed in from top to bottom outside spring outer diameter, be with in the inner chamber of female sleeve upper end and have one with externally threaded adjustable column, be pressed in the upper end of spring with externally threaded adjustable column lower plane, circular cushion block is fixedly connected with transformer coil, be with female sleeve to be fixedly connected with by folder, folder and transformer coil relative distance L are fixed.
There is an inner hexagonal hole described externally threaded adjustable column upper end.
Be socketed with back-up ring in the lower end with female sleeve.
The nail pressing groove of described cushion block is of a size of ￠ 45mm.
The described internal diameter size with female sleeve is ￠ 45mm.
The height of described spring is 80mm, and diameter is ￠ 36mm.
The internal diameter size of described nail pressing cover for seat is ￠ 40mm.
Described folder is channel-section steel.
Effect of the present utility model is: the utility model is disclosed is a kind of dry-type transformer coil nail pressing device, simple in structure, good manufacturability, reliability is high, easy to operate, carry out coil pressing by carry out the thrust that holddown spring produces with the threaded adjusting of externally threaded adjustable column, prevent dry-type transformer long-time running peculiar to vessel and cause coil loosening, strengthen the anti-short circuit capability of dry-type transformer peculiar to vessel, guarantee dry-type transformer safety peculiar to vessel, reliability service.
It is large that the utility model compresses area, is specially adapted to large capacity dry-type transformer peculiar to vessel, adopted flexible member, avoided the axial play of coil, and the utility model had both met being uniformly distributed of nail pressing, and had increased compression area, good manufacturability.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail:
Fig. 1 is the main cutaway view of the utility model;
In figure: 1, be with female sleeve; 2, back-up ring; 3, transformer coil; 4, nail pressing cover for seat, 5, cushion block; 6, spring; 7, folder; 8, with externally threaded adjustable column; 9, inner hexagonal hole.
Embodiment
As shown in Figure 1, dry-type transformer coil nail pressing device, comprise nail pressing cover for seat 4, spring 6, back-up ring 2, with externally threaded adjustable column 8, be with female sleeve 1, it is in circular nail pressing cover for seat 4 that its medi-spring 6 is arranged at inner chamber, and inner chamber is that to be located in inner chamber be in circular cushion block 5 to circular nail pressing cover for seat 4; Be with female sleeve 1 to be socketed in from top to bottom outside spring 6 external diameters, be with in female sleeve 1 upper end inner chamber and have one with externally threaded adjustable column 8, be pressed in the upper end of spring 6 with externally threaded adjustable column 8 lower planes, circular cushion block 5 is fixedly connected with transformer coil 3, be with female sleeve 1 to be fixedly connected with by folder 7, folder 7 and transformer coil 3 relative distance L are fixed, by regulate with externally threaded adjustable column 8 in the position with female sleeve 1, make spring 6 produce different deformation masterpieces and be used on circular cushion block 5.
