The damage of cable is not easily caused and the wiring operation of the cable wire is facilitated. Simultaneously the installation and using safety of the power distribution system is ensured, and the appearance of the transformer is improved.
Description
Technical field
The utility model relates to the oil-immersed power transformer technical field.
Background technology
At present, because based on conventional transformer structure design and be subjected to the restriction in conventional transformer structure space, the most of design of the high/low extrusion line position of the middle-size and small-size power transformer of oil immersed type that circulates on the market is in the outlet of case lid position.Along with continuous development for distribution field science and technology, town and country power supply-distribution system circuit changes the underground cable cabling mode into gradually by traditional overhead cabling mode, this causes the cabling mode that line position is not suitable for current underground cable that of traditional oil-immersed power transformer reservation, need cable is repeatedly torn open curved when power supply-distribution system installment work personnel are connected the power supply-distribution system circuit with power transformer, this is difficult and be unfavorable for that the construction that power supply-distribution system installment work personnel carry out power supply-distribution system lays and debugging with regard to causing wiring.In addition, cable is fragile and generation electric leakage danger after bending, to causing harmful effect the useful life of power supply-distribution system, has lowered the fail safe of power supply-distribution system.
The utility model content
Technical problem to be solved in the utility model provides the oil-immersed power transformer that a kind of power supply-distribution system circuit, wiring that is adapted to the cable underground cabling mode is easy, can avoid the cable bending.
For effectively solving the problems of the technologies described above, the technical scheme that the utility model is realized is: a kind of oil-immersed power transformer, comprise fuel tank and the device body that is immersed in fuel tank internal, the device body is provided with high-voltage conducting wires terminal and the primary cable terminal that is used to connect extraneous cable, and described high-voltage conducting wires terminal and primary cable terminal stretch out the fuel tank outside by the fuel tank sidewall.
Described high-voltage conducting wires terminal and primary cable terminal have been with the bushing and the low-tension bushing of insulation protection effect respectively, and described fuel tank sidewall is provided with respectively bushing and low-tension bushing risen and carries raise seat and low pressure of the high pressure of pretending usefulness and raise.
Described high pressure seat and the low pressure seat that raises that raises is arranged at fuel tank both sides sidewall respectively, and the described high pressure seat that raises upwards becomes 60 ° of angles with the fuel tank sidewall, and it is vertical with the fuel tank sidewall that described low pressure raises.
The beneficial effects of the utility model are: it is outside and be provided with respectively bushing and low-tension bushing risen at the fuel tank sidewall and carry raise seat and low pressure of the high pressure of pretending usefulness and raise that high-voltage conducting wires terminal of the present utility model and primary cable terminal stretch out fuel tank by the fuel tank sidewall, make going out line position setting and adapting to cable underground cabling mode power supply-distribution system circuit of oil-immersed power transformer, the bending of cable when effectively avoiding the power supply-distribution system circuit to be connected with power transformer, be difficult for causing the cable damage and be convenient to cable wiring work, ensured the installation of power supply-distribution system and safe in utilization simultaneously, it is aesthetic in appearance also to help transformer.High pressure rising seat in the utility model upwards becomes 60 ° of angles with the fuel tank sidewall, low pressure rising seat is vertical with the fuel tank sidewall, the wiring of be more convenient for high pressure cable and low pressure cable.

Fig. 2 is the utility model lower-left TV structure schematic diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
As Fig. 1,2, the utility model discloses a kind of oil-immersed power transformer, comprise fuel tank 1 and the device body that is immersed in fuel tank internal, the device body is provided with high-voltage conducting wires terminal 21 and the primary cable terminal 22 that is used to connect extraneous cable, and described high-voltage conducting wires terminal and primary cable terminal stretch out the fuel tank outside by the fuel tank sidewall.High-voltage conducting wires terminal of the present utility model and primary cable terminal stretch out the fuel tank outside by the fuel tank sidewall, can be adapted to the power supply-distribution system circuit of cable underground cabling mode preferably, when being convenient to wiring and can avoiding wiring with the cable bending.For strengthening fail safe of the present utility model, present embodiment mesohigh conductor terminal and primary cable terminal have been with the bushing 23 and the low-tension bushing 24 of insulation protection effect respectively.For bushing and low-tension bushing are fixed on the fuel tank sidewall, and the direction that high-voltage conducting wires terminal and primary cable terminal stretch out the fuel tank sidewall played guiding function, the fuel tank sidewall is provided with respectively bushing and low-tension bushing risen and carries the high pressure of pretending usefulness seat 11 and the low pressure seat 12 that raises that raises.
In the present embodiment, high pressure rising seat and low pressure rising seat are arranged at fuel tank both sides sidewall respectively, this helps high-voltage conducting wires terminal and primary cable terminal are separated, be convenient to make the high-voltage conducting wires terminal to be connected extraneous cable from different directions with the primary cable terminal, help adapting to the cable underground cabling mode, and can further guarantee fail safe of the present utility model.In addition, high pressure rising seat in the present embodiment upwards becomes 60 ° of angles and low pressure rising seat vertical with the fuel tank sidewall with the fuel tank sidewall, both guaranteed the novelty of electrical safety distance with outward appearance, realized making things convenient for the purpose of high pressure and the wiring of low pressure cable again, reduced the curved position of tearing open of cable simultaneously, solved cable owing to tearing the curved difficult problem that has caused the wiring difficulty open.
When installing and using this oil-immersed power transformer, at first the utility model is fixed on the corresponding infrastructure, again the underground cable line is drawn and be fixed on the cable support frame, at last cable is directly upwards extended and according to corresponding installation specification high pressure and low tension cable are carried out wiring with bushing and low-tension bushing respectively and get final product.
The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also should fall within the protection range of the present utility model.
