Abstract
A combined type buried transformer is characterized in that the transformer comprises a prefabricated underground foundation and a lamp-house type outdoor low-voltage switch cabinet positioned above the prefabricated underground foundation; and the transformer adopts an underground transformer which is installed inside the prefabricated underground foundation, low-voltage configurations including capacitance compensation are arranged inside the lamp-house type outdoor low-voltage switch cabinet, the high-voltage side is connected with the transformer body through an elbow-shaped cable, the low-voltage side is led out from the lamp-house type outdoor low-voltage switch cabinet positioned above the foundation through a cable chute, high-voltage and low-voltage cable plugs on the transformer are arranged inside a seal box, and a waterproof sealing structure is arranged at the cable-leading out site. The combined type buried transformer does not occupy ground surface area, and can avoid suffering from unconscious or malicious destroys from surroundings and ensure power distribution reliability. The low-voltage configurations are hidden inside the advertising lamp house, so as to solve the problems of the low-voltage configurations of the transformer and improve the city view.
Description
Technical field
The utility model relates to power equipment, a kind of distribution equipment of more specifically saying so.
Background technology
Power distribution network be in the electrical network quantity at most, fault and safeguard probability the highest, with the closest part of power consumer relation.In recent years, the properties of product of power distribution network, operation conditions, economic benefit and the status in electrical network thereof have obtained the extensive concern of Utilities Electric Co. and society.Along with socioeconomic continuous development, the requirement of distribution network is also improving constantly, in the modern city of distribution network arranged in high density, people not only more and more pay attention to power supply capacity, operational reliability and the security performance of distribution facility, and the state of appearance of noise problem, transformer and relevant power distribution cabinet facility also is to influence the living of the people and the key factor of city integral image.After the removal of old city, road widening, urban network restructuring are gone through in the urban construction of China, just stepping into the beauty treatment stage of improving streetscape city looks.But many box-type substations not only tie up gold ground, downtown area, and unordered spoiling the fun straggly, and in the residential quarter in city, because popular for the worry of electromagnetic radiation, to the raising of healthy values, make and made us keeping out of the way three fens with the unit of power distribution room for the neighbour in the sub-district.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of composite type buried change, take surface area in the hope of reducing as far as possible, improve cityscape, avoiding suffering destruction, the assurance power supply reliability of unintentionally extraneous or malice simultaneously.
The utility model technical solution problem adopts following technical scheme:
The design feature of the buried change of the utility model composite type is:
The design feature of the buried change of the utility model composite type is to comprise prefabricated underground foundation that is installed in the melt pit and the lamp box type outdoor low voltage cabinet that is positioned on the prefabricated underground foundation; Adopt underground transformer, underground transformer is installed in the prefabricated underground foundation, the low pressure configuration that comprises capacitance compensation is arranged in the lamp box type outdoor low voltage cabinet, the high-pressure side connects the transformer body by elbow type cable, low-pressure side is drawn from the lamp box type outdoor low voltage cabinet that is positioned on the melt pit by cable trough, each high-low pressure cable plug is arranged in the seal box on the transformer, and at the cable place of drawing waterproof sealing structure is set.
The design feature of the buried change of the utility model composite type also is:
At the lamp box type outdoor low voltage ventilation and heat mouth is set cashier's office in a shop, and in lamp box type outdoor low voltage cabinet, Forced discharge fan is installed.
Melt pit hole wall is to be material with the 8mm steel plate.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is to be prefabricated in the factory to assemble the underground type change distribution complete set of equipments of finishing, because its transformer is installed in the melt pit, take surface area after the installation hardly, and can avoid suffering the destruction of unintentionally extraneous or malice, guarantee power supply reliability, the low pressure configuration is hidden in the advertising lamp box, has both solved the transformer low voltage allocation problem, has improved the style and features in city again.
2, the in-situ balancing of the compensation realization power system reactive power of the utility model employing reduces electricity and decreases, raising rate of qualified voltage, the reliability of raising equipment operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 melt pit, 2 prefabricated underground foundations, 3 lamp box type outdoor low voltage cabinets, 4 underground transformers, 5 elbow type cables, 6 seal boxes, 7 ventilation and heat mouths, Final 8's exhaust blower, 9 plate radiating plates, QF circuit breaker, FK combination switch, C electric capacity, TTU controller.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, the buried change of present embodiment composite type comprises prefabricated underground foundation 2 that is installed in the melt pit 1 and the lamp box type outdoor low voltage cabinet 3 that is positioned on the prefabricated underground foundation 2; Adopt low-loss and have the underground transformer 4 of plate radiating plate 9, underground transformer 4 is installed in the prefabricated underground foundation 2; The low pressure configuration that comprises capacitance compensation is arranged in the lamp box type outdoor low voltage cabinet 3, the high-pressure side connects the transformer body by elbow type cable 5, low-pressure side is drawn from the lamp box type outdoor low voltage cabinet 3 that is positioned on the melt pit by cable trough, each high-low pressure cable plug is arranged in the seal box 6 on the transformer, and at the cable place of drawing waterproof sealing structure is set.
In concrete the enforcement, corresponding structure is set to:
On lamp box type outdoor low voltage cabinet 3, ventilation and heat mouth 7 is set, and in lamp box type outdoor low voltage cabinet 3, Forced discharge fan 8 is installed,, strengthen heat radiation to strengthen air circulation.When the underground type transformer made temperature rise reach set point because of long-term overload operation, control Forced discharge fan 8 put into operation, implemented the cooling of air draft by force.
Melt pit 1 is to be main material with the 8mm steel plate, adopts the boats and ships surface spray coating process, can reach good antiseptic effect.Capacitance compensation C utilizes controller TTU and combination switch FK to carry out three-phase to mend altogether and divide to mend and combine, the composite switching mode of " phase-splitting+balance ", realize the in-situ balancing of power system reactive power, decrease to reduce electricity, improve rate of qualified voltage, improve the reliability of equipment operation, circuit breaker Q F is provided with routinely.
