Along with the continuous 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 pressure nail of present dry-type transformer coil peculiar to vessel all is that the screw rod processing and fabricating forms, and cooperates to press the nail locking nut to compress coil, and it mainly relies on screw thread to tighten.Dry-type transformer peculiar to vessel has to tilt and wave and the shrinkage factor of insulating part, cushion block etc. in the long-time running process, press nail to be very easy to occur loosening, coil can't be compressed and cause becoming flexible, thereby greatly reduce dry-type transformer anti-short circuit capability peculiar to vessel, when being short-circuited, can cause dry-type transformer coil peculiar to vessel to be burnt.
Summary of the invention
The present invention is directed to the defective that present above-mentioned pressure nail exists, a kind of simple structure, high reliability is provided, and good manufacturability, highly versatile, can effectively reduce and press the loosening phenomenon of nail, improve the anti-short circuit capability of dry-type transformer peculiar to vessel, guaranteed the dry-type transformer coil stapling machine structure of dry-type transformer operational reliability peculiar to vessel.
In order to solve above-mentioned pressure nail defective, the present invention adopts following technical scheme: dry-type transformer coil stapling machine structure, it is characterized in that: comprise and press the nail cover for seat, spring, back-up ring, have externally threaded adjustable column, have the sleeve of internal thread, its medi-spring is arranged at inner chamber in the circular pressure nail cover for seat, and inner chamber is located in inner chamber in the circular cushion block for circular pressure nail cover for seat; The sleeve that has internal thread is socketed in outside the spring external diameter from top to bottom, having in the sleeve upper end inner chamber of internal thread has to have an externally threaded adjustable column, have the upper end that externally threaded adjustable column lower plane is pressed in spring, circular cushion block is fixedlyed connected with transformer coil, the sleeve that has internal thread is fixedly connected by folder, folder and transformer coil relative distance L are fixed, have externally threaded adjustable column in the position of the sleeve that has internal thread by adjusting, make spring produce different deformation masterpieces and be used on the circular cushion block.
There is an inner hexagonal hole described externally threaded adjustable column upper end, acts on the inner hexagonal hole adjusting by die nut and has externally threaded adjustable column, and the contact-making surface of pressing nail cover for seat and cushion block is increased.
Lower end at the sleeve that has internal thread is socketed with back-up ring, is used for the downward position of spacing folder.
The pressure nail groove of described cushion block is of a size of ￠ 45mm.
The described internal diameter size that has the sleeve of internal thread is ￠ 45mm.
The height of described spring is 80mm, and diameter is ￠ 36mm.
The internal diameter size of described pressure nail cover for seat is ￠ 40mm.
Described folder is channel-section steel.
Effect of the present invention is: disclosed by the invention is a kind of dry-type transformer coil stapling machine structure, simple in structure, good manufacturability, the reliability height, easy to operate, the thrust of coming holddown spring to produce by the threaded adjusting that has externally threaded adjustable column compresses coil, prevents dry-type transformer long-time running peculiar to vessel and causes 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 big that the present invention compresses area, is specially adapted to big capacity dry-type transformer peculiar to vessel, adopted flexible member, avoided the axial play of coil, and the present invention had both satisfied the even distribution of pressing nail, and increased and compress area, good manufacturability.
