Abstract
The utility model provides a rectifier insulating tube, which comprises an insulating tube body. An opening which is helpful for sheathing a rectifier into is arranged at one end of the tube body, and the tube body comprises an inner layer, an outer layer and an intermediate layer. During usage, the rectifier insulating tube can be sheathed on the rectifier to enhance insulation effect, so that the rectifier can be put into an oil tank with reduced volume. The utility model also provides a transformer which comprises an oil tank. The insulating tube and the rectifier are arranged inside the oil tank, the insulating tube is sheathed on the rectifier, the oil tank is filled with insulating oil, and the insulating tube and the rectifier are immerged inside the insulating oil. The oil tank volume of the transformer provided by the utility model is smaller than the oil tank volume of the common transformer, which requires less insulating oil to be filled, saves materials and cost and facilitates carrying.
Description
Technical field
The utility model relates to rectifier and transformer.
Background technology
Electric precipitation is formed an organic whole with transformer by transformer and high tension silicon rectifier, being placed on one is full of in the fuel tank of insulating oil, high-voltage rectifier is generally full-wave rectification bridge, the work incoming end is the alternating current after boosting, be generally 72kV, therefore when design the type transformer, distance is bigger between the ground connection parts such as rectifier and transformer core clamping, fuel tank, could guarantee that transformer normally moves.
Because distance is bigger between the fuel tank of rectifier and this rectifier of dress, so the size of fuel tank often must be done very greatly, large-sized fuel tank need be filled more transformer insulation oil, makes the transformer total weight very big, makes troubles for transportation, installation.
Summary of the invention
Thereby technical problem to be solved in the utility model provides a kind of distance of can dwindling between rectifier and the fuel tank dwindles the fuel tank volume, saves the rectifier insulating cylinder of insulating oil, for this reason, the utility model by the following technical solutions:
It comprises insulating cylinder body, and described cylindrical shell one end is provided with the opening that makes things convenient for rectifier to be inserted in, and described cylindrical shell comprises internal layer, skin and intermediate layer.
By above technical scheme, the utility model when in use can be by being enclosed within on the rectifier, and the reinforced insulation effect makes this rectifier can put into the fuel tank after the volume-diminished.
Another technical problem to be solved in the utility model provides that a kind of volume is less, the transformer of convenient in carrying, and for this reason, the utility model adopts following technical scheme:
It comprises fuel tank, be provided with insulating cylinder body as claimed in claim 1 in the described fuel tank, also be provided with rectifier in the described fuel tank, described insulating cylinder body is enclosed within on the described rectifier, also be filled with insulating oil in the described fuel tank, described insulating cylinder body and rectifier are dipped in this insulating oil.
By above technical scheme, fuel tank volume ratio common transformer fuel tank volume of the present utility model is littler, needs transformer insulation oil still less to fill, economical with materials and cost and carry more convenient.
Description of drawings
Fig. 1 is the structural representation of 1 one kinds of rectifier insulating cylinders of the utility model embodiment.
Fig. 2 is the schematic top plan view of 2 one kinds of transformer open modes of the utility model embodiment.
Embodiment
With reference to accompanying drawing 1.The utility model comprises the insulating cylinder body 1 that can be immersed in for a long time in the oil, one end of this insulating cylinder body 1 is provided with the opening 2 that conveniently is inserted in rectifier, described cylindrical shell 1 comprises internal layer 3, intermediate layer 4 and outer 5, between described internal layer 3 and the intermediate layer 4, can be respectively equipped with between the intermediate layer 3 and outer 5, also can select to be provided with packed layer.In the present embodiment, between internal layer 3 and the intermediate layer 4, be equipped with packed layer between the intermediate layer 3 and outer 5, this packed layer is surge layer 6 and surge layer 7, and described surge layer connects together internal layer and intermediate layer glue, also can connect without glue, adopts the mode of hot pressing.
The use of described surge layer has two purposes, and the one, better reinforced insulation, another is in order to save more material when increasing cylindrical shell thickness, to make that simultaneously this cylindrical shell quality is lighter.
Insulating cylinder body 1 adopt can be immersed in the oil for a long time and the material of insulation all can, in order to reach best technique effect, in the utility model, adopt pure wood pulp cellulose material.Described internal layer, intermediate layer, skin are the thick pure wood pulp cellulose cardboard of 1～2mm, and promptly the thick pure wood pulp cellulose cardboard of insulating cylinder body 1 usefulness 1～2mm is hot-forming.
When the utility model uses, insulating cylinder body 1 is inserted on the rectifier, in the fuel tank of again insulating cylinder body 1 and rectifier being packed into together.Because insulating cylinder body 1 can be brought good insulating properties, make that the distance of rectifier and oil tank wall can be reduced significantly.Rectifier to fuel tank internal distance usually more than or equal to 100mm, this distance can reduce to 50mm after installing the utility model additional, promptly can make fuel tank length dwindle 50mm, and the fuel tank cavity volume reduces 30～50 liters, transformer can fill 30～50 liters of insulating oils less, greatly economizes on resources and cost.The utility model is easy to use, and material is selected easily.
With reference to accompanying drawing 2.The utility model comprises fuel tank 21, be provided with the 1 described insulating cylinder body 22 as embodiment in the described fuel tank, also be provided with rectifier 23 in the fuel tank 21, insulating cylinder body 22 is enclosed within on the rectifier 23, also be filled with insulating oil in the fuel tank 21, insulating cylinder body 22 and rectifier 23 are dipped in this insulating oil.
Insulating cylinder body 22 is pure wood pulp material, can be immersed in for a long time in the insulating oil, one end of insulating cylinder body 22 is provided with the opening 25 that conveniently is inserted in rectifier, this insulating cylinder body 22 comprises internal layer 26, intermediate layer 27 and outer 28, between described internal layer 26 and the intermediate layer 27, can be respectively equipped with between the intermediate layer 27 and outer 28, also can select to be provided with packed layer.In the present embodiment between internal layer 26 and the intermediate layer 27, be equipped with packed layer between the intermediate layer 27 and outer 28, this packed layer is surge layer 29 and surge layer 30, described surge layer connects together internal layer and intermediate layer glue, also can connect without glue, adopts the mode of hot pressing.
The use of described surge layer has two purposes, and the one, better reinforced insulation, another is in order to save more material when increasing cylindrical shell thickness, to make that simultaneously this cylindrical shell quality is lighter.
In order to reach best technique effect, in the utility model, adopt pure wood pulp cellulose material.Described internal layer, intermediate layer, skin are the thick pure wood pulp cellulose cardboard of 1～2mm, and promptly the thick pure wood pulp cellulose cardboard of insulating cylinder body 22 usefulness 1～2mm is hot-forming.
When the utility model is installed, earlier insulating cylinder body 22 is inserted on the rectifier 23, in the fuel tank 21 of again insulating cylinder body 22 and rectifier 23 being packed into together.Because insulating cylinder body 22 can be brought good insulating properties, make that the rectifier 23 and the distance of oil tank wall can be reduced significantly.Rectifier to fuel tank internal distance usually more than or equal to 100mm, this distance can reduce to 50mm in the utility model, promptly can make fuel tank length dwindle 50mm, the fuel tank cavity volume reduces 30～50 liters, be that the utility model can fill 30～50 liters of insulating oils less, greatly economize on resources and cost, and carry convenient.
