Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to this utility model.
Embodiment：As shown in figs 1 to 6, a kind of distribution transformer arrangement, including the two cement electricity installed in taper
Three-Phase Distribution Transformers 1 on bar 4, in H type structures, in the side of Three-Phase Distribution Transformers 1 single phase distribution transformer are installed additional
2, single phase distribution transformer 2 is arranged on one section that stretches out a cement electric pole 4 of channel-section steel cross-arm 3, solid in the level of channel-section steel cross-arm 3
Surely it is erected on two cement electric poles 4, the outfan of single-phase transformer 2 is connected to TTU termination racks 10, input and power transmission three-phase
On electric lines of force on line.
Preferably, above-mentioned channel-section steel cross-arm 3 stretches out one section of cement electric pole 4 and is arranged with inclined porcelain load support brace 5, porcelain
The one end of load support brace 5 is connected on channel-section steel cross-arm 3, and the other end is connected on U-shaped anchor ear 6, and U-shaped anchor ear 6 is fixedly connected on water
On mud electric pole 4, rigidity of support more preferably, supports more stable, and connection is reliable, loads and unloads easy to maintenance.
Preferably, above-mentioned channel-section steel cross-arm 3 includes two channel-section steels 7 and bolt 8 of two cement electric poles 4 of back-to-back pincer attack, per root
Two bolts 8 are set at cement electric pole 4, two channel-section steels 7 are fixedly connected on cement electric pole 4 by four bolts, connection is reliable,
Handling are easy to maintenance, and the bottom of two channel-section steel 7 is provided with steps up anchor ear 11 and support, and further improve stability of strutting system and the connection of channel-section steel
Reliability, single phase distribution transformer 2 across the two parallel chocks 9 on two channel-section steels 7 by being connected on channel-section steel cross-arm 3.
Preferably, the both sides of above-mentioned Three-Phase Distribution Transformers 1 all install a single phase distribution transformer 2 additional, install additional two it is single-phase
Distribution transformer, can further improve electrical stability and supply district, only need to stretch out one section by above-mentioned channel-section steel cross-arm 3 is two-way
Two single phase distribution transformers are installed, is transformed convenient and simple.
Preferably, above-mentioned Three-Phase Distribution Transformers 1 are replaced by single phase distribution transformer 2, because of each single phase distribution transformation
The output power of device can reach 250kVA, be powered according to three single phase distribution transformers 2, and output power is up to 750
KVA, and the maximum output power of three-phase transformer is 400 kVA, thus powered using three single phase distribution transformers and more may be used
By stable.
Using the advantage of single phase distribution transformer：
Open circuit loss declines notable under identical capacity.Such as one capacity is its sky of the single phase distribution transformer of 50 kVA
Load-loss is 135 W, and the open circuit loss of S9 series three phases distribution transformer is 170 W under identical capacity, and both differ 35 W,
8000 h meters are run per year, and single phase distribution transformer is fewer than S9 series three phase distribution transformers to lose the kWh of electricity 280；
Low-voltage Line Loss declines obvious.The radius of electricity supply of single phase distribution transformer is only 10～15 m, with three-phase distribution transformation
Device is compared, and radius of electricity supply is greatly shortened, and Low-voltage Line Loss is decreased obviously, through checking meter, counting, the Low-voltage Line Loss of above-mentioned experimental county
Rate drops to 2.72% from 7.61%, the moon 1810 kWh of amount of electricity saving；
Rate of qualified voltage is significantly improved.Because radius of low voltage power supply is greatly shortened, line voltage distribution loss is little, closes to family voltage
Lattice rate is significantly improved；
Customer power supply reliability is improved.One single phase distribution transformer is only powered to 10-20 families resident, is matched somebody with somebody when single-phase
When becoming failure, impacted resident's amount is greatly decreased, and the power supply reliability of distribution line obtains larger raising；
Powered using single phase distribution transformer, high-tension line can be set by two coil holders, low-voltage circuit can be by two lines or three coil holders
If, and powered using Three-Phase Distribution Transformers, high-tension line must be set by three coil holders, and low-voltage circuit is set by four coil holders.From engineering
From the point of view of expense, using single phase distribution transformer high and low pressure line project cost of powering 1/5 can be saved；
It is used for from platform area cost of erection, building a H types power distribution station material needs 6000 yuan or so of funds, and single phase distribution becomes
Depressor adopts 2000 yuan of single pole suspension type material one-house show.Therefore, platform area expense can save 2/3 fund.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any those familiar with the art can readily occur in change in the technical scope that this utility model is disclosed
Or replace, all should cover within protection domain of the present utility model, therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
