Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The box-type substation of underground transformer of an embodiment of the utility model has been shown among Fig. 1.This box-type substation comprises: transformer station's ground lower box 4, underground transformer 1, prefabricated melt pit substrate 2, lamp box type power distribution cabinet 3; Wherein, underground transformer 1 places ground lower box 4, and ground lower box 4 is arranged on below ground, can be in basement or the melt pit; On ground lower box 4, be covered with prefabricated melt pit substrate 2, on prefabricated melt pit substrate 2, lamp box type power distribution cabinet 3 be set, have louvered ventilating mechanisms 31 on the lamp box type power distribution cabinet 3.This box-type substation can assembled in advance become complete set of equipments in factory, electric property is suitable with traditional box-type substation.Advertising lamp box and louvered ventilating mechanisms 31 are connected as a single entity; The advertisement picture is set in the advertising lamp box; Make each prepackage underground type box type transformer especially like a large-scale television set, thereby constitute the beautiful scenery line, play the effect of decorating the city, beautifying the environment.
Referring to Fig. 2, the box-type substation of underground transformer also comprises the operation cover plate 21 that is arranged on the prefabricated melt pit substrate 2, opens and should operate cover plate 21, is convenient to the maintenance to underground transformer 1.On the sidewall of ground lower box, be provided with low-voltage cable wire hole 41 and high-tension cable entrance hole 42, be used to link up underground transformer 1 and be connected with the cable of electric power networks.
Further, below the utility model also has preferred embodiment:
(1) ventilation and heat of underground transformer
1. the temperature rise control of underground transformer main body: the underground transformer of selecting for use is 11 serial low-loss products, adopts low temperature rise design to the subway transformer characteristics, guarantees the low at least 10K of transformer body temperature rise ratio GB.
2. the selection of underground transformer main coil insulating material: the coil insulation material thermal endurance class of selecting for use is brought up to B level (130 ℃ of heatproofs) or above material by A level (105 ℃ of heatproofs); The coil insulation margin of temperature rise has improved 25K than common oil-filled transformer, thereby improves the capability of overload of transformer.
3. underground transformer main body radiating mode: the fuel tank fin of underground transformer adopts flat design, effectively the enhanced rad heat-sinking capability; In addition, can also adopt the underground transformer of import cycloalkyl transformer oil.The cycloalkyl transformer oil must not add additive just can be in continuous flow under the extremely low temperature, and its good viscosity-time response makes that the flowing velocity of oil is accelerated when temperature raises, and guarantees that product has good heat-sinking capability.
4. the Design of ventilation of melt pit substrate: have good air permeability in order to make melt pit inside, adopted the melt pit board structure of expanded type.Because the whole supporting installation of the box-type substation of street lamp underground transformer, so civil engineering only need dig pit by drawing, and makes the concrete mounting plane.Between power distribution cabinet and melt pit, in the advertising lamp box, be provided with the ventilation and heat mouth, realize the natural draft heat radiation of transformer.Increase air intake and air-out blower fan simultaneously,, start the strong supply and exhaust cooling of fan, guarantee the normal operation of underground transformer when the underground type transformer reaches 75 when spending because of long-term overload operation causes temperature (fuel tank oil tube wall temperature).
(2) protected against the effects of immersion of the waterproof of melt pit substrate, draining and underground transformer
1. the design and installation technology of underground transformer body:
The hv cable termination head adopts that import is hermetically sealed, all insulation EDPM elbow cable plug or homemade hermetically sealed, all insulation LSR silicon rubber prefabricated cable head; Low pressure adopts import waterproof gasket cement parcel and overcoat import waterproof heat-shrink tube, and the high-low pressure termination is placed in the stuffing box, can satisfy the requirement of long-time running under water.
2. the design of lower box:
The ground lower box can adopt whole steel sheet and strengthen using the channel-section steel Welding Structure, the zinc-plated and spray antisepsis finishing paint processing of overall thermal; The melt pit substrate adopts hermetic reinforced concrete structure cover plate; Adopt rubber weather strip to carry out water-proofing treatment between substrate and the ground lower box, guarantee that surface water, underground water and other foreign material can not get in the melt pit.
3. automatic Drainage Design:
Immersible pump is set in the ground lower box, automatic drain system is installed.When because of fortuitous events such as heavy rain, flood cause the melt pit inner inlet, start drainage system automatically and carry out draining.
(3) the underground transformer shell is anticorrosion
Select the low-alloy structural steel manufacturing for use, the body antiseptic power is good than carbon structural steel; The treatment process standard meets and is embedded in the steel that soak under the soil, the processing requirements of the underground culvert of steel conduit.
(4) protection of the box power distribution cabinet of outdoor lights
Power distribution cabinet in the lamp box shell adopts the two storied gate structure, and the ground floor door is a protective door, can not operate controller switching equipment to guarantee unwarranted people; Second layer door is the instrument door, the safety during with the operation of assurance controller switching equipment.
Box-type substation according to the underground transformer of the utility model has following beneficial effect:
(1) economic benefit
Compare at most traditional box-type substation of fortune, the underground transformer box-type substation has three big advantages in economical operation:
1, adopt the low low-loss transformer of temperature rise, indexs such as no-load loss, load loss are superior to the S9 serial transformer that traditional box substation generally adopts greatly, and are equivalent to or are superior to S11 serial transformer, energy savings.
2, the non-maintaining cycle of underground transformer long, directly save maintenance cost.
3, to take the area on the face of land little for the underground transformer box-type substation; The less-restrictive of installing, thus position can be installed near load center, thus effectively shortened the low-voltage power supply radius; Not only practiced thrift a large amount of cable costs of investment, the line loss in city is significantly reduced.
(2) social benefit and application prospect
Street lamp underground transformer box-type substation has solved street lamp power supply, road lamp power supply facility and the inharmonic contradiction of environmental beauty effectively, can enhance each other's beauty with peripheral view; The advertisement type lamp box can also be placed slogan or the picture poster that has nature of public service, for the universal of work for the public good added fuel to the flames; Adopt the underground transformer case to beautify the environment, floor space is little simultaneously, can improve urban environment better, promotes city integral image.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
