Abstract
The utility model relates to a dry -type transformer, coil install on the iron core, and the folder is installed at both ends about the coil, is equipped with the resin cushion piece between coil and the folder, and the lower margin backing plate is installed to the folder bottom of coil lower extreme, high -pressure coil and low voltage coil that the coil is in the same place including the cover, its characterized in that: accompany an epoxy section of thick bamboo between high -pressure coil and the low voltage coil. The beneficial effects of the utility model are that, 1. The effectual air flue blocking phenomenon who avoids the cushion below, 2. Folder and lower margin backing plate adopt the stainless steel preparation, are difficult for rustting, and the outward appearance is beautiful, 3. Adopt a fashioned epoxy section of thick bamboo, be convenient for place the installation, can be as general, production efficiency is high.
Description
Technical field
This utility model belongs to transformer equipment field, relates to a kind of dry-type transformer new construction.
Background technology
Present stage, air flue is due to cushion block width below cushion block for traditional dry type transformer structure, and air flue interval is little, easily occurs airway obstruction below cushion block, affects coil heat radiation, causes coil temperature rise too high；Folder and lower margin backing plate use channel-section steel structure, need to carry out acid washing phosphorization, the operation such as spray paint just can be installed and used, and operation is many, and easily gets rusty, unsightly；Placing the insulation of 1mmPET soft paper web between high-low pressure, yielding being unfavorable for is installed, and insulation effect is poor.
Summary of the invention
This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, dry-type transformer new construction easy to use.
This utility model is achieved by the following technical solution:
Dry-type transformer new construction of the present utility model, coil is arranged on iron core, folder is installed at the upper and lower two ends of coil, resin cushion block it is provided with between coil and folder, mounting foot backing plate bottom the folder of coil lower end, coil includes high-tension coil and the low-voltage coil being nested together, it is characterised in that: accompany epoxy resin cylinder between high-tension coil and low-voltage coil.
On resin cushion block, the one side near coil has air channel.
Folder and lower margin backing plate are respectively adopted corrosion resistant plate and are converted into U-shaped.
Epoxy resin barrel thickness 3mm.
The beneficial effects of the utility model are, the most effectively avoid the airway obstruction phenomenon below cushion block；2. folder and lower margin backing plate use rustless steel to make, and are difficult to get rusty, and outward appearance is beautiful；3. use the epoxy resin cylinder of molding, it is simple to place and install, can be as general part, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is front view schematic diagram of the present utility model.Fig. 2 is the top view schematic diagram of Fig. 1, and Fig. 3,4,5 are followed successively by the front view of resin cushion block, left view, top view schematic diagram.
In figure: 1 folder, 2 cushion blocks, 3 lower margin backing plates, 4 air flue holes, 5 high-tension coils, 6 epoxy resin cylinders, 7 low-voltage coils, 8 air channels.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.
Dry-type transformer new construction of the present utility model, coil is arranged on iron core, folder 1 is installed at the upper and lower two ends of coil, resin cushion block 2 it is provided with between coil and folder, mounting foot backing plate 3 bottom the folder of coil lower end, coil includes high-tension coil 5 and the low-voltage coil 7 being nested together, and accompanies epoxy resin cylinder 6 between high-tension coil and low-voltage coil.
On resin cushion block, the one side near coil has air channel 8.
Folder and lower margin backing plate are respectively adopted corrosion resistant plate and are converted into U-shaped.
Epoxy resin barrel thickness 3mm.
Dry-type transformer new construction of the present utility model, 1. opens air drain in the middle of the lower section of cushion block, makes the gas in the air flue hole 4 below resin cushion block to flow, it is to avoid below cushion block, " dead air flue " exists, it is simple to heat radiation；2, folder and lower margin backing plate use corrosion resistant plate to be converted into U-shaped, are not required to acid washing phosphorization, the operation such as spray paint, and technological process is simple, will not get rusty, and outward appearance is beautiful；3. place the epoxy resin cylinder of 3mm molding between high and low pressure coil, be unlikely to deform, improve insulating properties, it is simple to place and install, can be as general part, production efficiency is high.
