Description
Technical field
The utility model relates to a kind of power transformation technology of sending, and the power transformation case is used in specifically a kind of construction site temporarily.
Background technology
The wet type power transformer of traditional oil immersion cooling is substituted by dry-type transformer, because the dry-type transformer volume is little, fail safe good, be mounted on the ground more, a box outer case is being built in the outside then, therefore have the transformer station of the dry-type transformer composition of box outer case, also be box-type substation.
Box type transformer normally is fixed on the support top that is formed by concrete casting, and support generally is to dig pit on ground according to the occupation of land size of outer case, carries out template, pours into semi-underground type, and promptly 2/3rds underground, and 1/3rd on the ground.Outer case is also mostly to be on-the-spot processing and fabricatings.The deficiency that this box-type substation base of prior art exists in actual applications is, (1) difficulty of construction is big, is subject to temperature and climatic influences in the work progress, such as construction in the winter time, concrete stirring, transportation and cast then are subjected to the influence of temperature, then are subjected to the influence of rainwater in summer; (2) consume a large amount of construction material and manpower and materials; (3) long construction period, used the same day of can not constructing the same day; (4) if site construction finishes, box outer case is then removed because of the building site resettlement, transformer in the outer case, outer case and other relevant devices can remove, but the cement base that stays then is difficult to remove, and causes environmental pollution even mechanical removal also will produce a large amount of building wastes; Also there is not at present good solution.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and convenient installs, detachable and make things convenient for the power supply management personnel that the power transformation case is used in the construction site that box type transformer overhauls temporarily.
Realize with the power transformation case temporarily in the following manner in the purpose of this utility model construction site, the power transformation case is by precast base, steel frame, dry-type transformer, service work pedal and outer case are formed, dry-type transformer is fixed on the steel frame, steel frame and outer case wallboard are fixed together by anchor bolt and precast base, precast base is provided with anchor perforation and cable and wire perforation, grounding anchor rod passes anchor perforation precast base is fixed on the ground surface, pass the electric wire perforation from underground cable and wire and be connected with dry-type transformer and relevant device thereof with steel frame, the service work pedal fixes together by the triangle hanging hole of triangle fastener and steel frame side.
Detachable box-type substation advantage of the present utility model is: because work progress is without earth excavation, thus be not subjected to climatic influences, and construction volume is little, short construction period, all parts all can be reused, and do not have raw materials consumption, have significantly reduced construction cost.If the power transformation case needs to remove, can use hoisting equipment to entruck and carry away pulling down piecemeal at the bottom of outer case, transformer, support and the precast concrete easily, very convenient and practical.In the ordinary maintenance process of power transformation case, in the limit of dry-type transformer steel frame portion demountable service work pedal is set, when the maintainer need overhaul transformer, maintenance pedal is connected to the side of transformer support, like this, the maintainer can stand on the maintenance pedal and work, and it is very handy to work together, promptly improve operating efficiency, also reduced labour intensity.
Description of drawings
Accompanying drawing 1 is the overall structure schematic diagram of construction site with the power transformation case;
Accompanying drawing 2 is construction site power transformation case steel frame and Working pedal plan structure schematic diagram;
Accompanying drawing 3 is the structural representation between construction site usefulness power transformation case steel frame and the Working pedal.
Mark in the accompanying drawing is represented respectively; Outer case is foot bolt 1 regularly; Anchor bolt 2; Electric wire perforation 3; Ground connection reinforcing bar 4; Precast base 5; Grounding anchor rod 6; Anchor perforation 7; Steel frame 8; Outer case 9; Gusseted 10; Working pedal 11; Dry-type transformer 12; Cable 13; Triangle hanging hole 14; Triangle fastener 15.
Embodiment
Below in conjunction with accompanying drawing folding case of the present utility model is become support and do following detailed description the in detail.
Shown in accompanying drawing 1-2, construction site of the present utility model is by precast base 5 with the power transformation case, steel frame 8, dry-type transformer 12, service work pedal and outer case 9 are formed, dry-type transformer 12 is fixed on the steel frame 8, steel frame 8 and outer case 9 by anchor bolt 2 and outer case regularly foot bolt 1 be fixed together with precast base 5, precast base 5 is provided with anchor perforation 7 and cable and wire perforation 3, grounding anchor rod 6 passes anchor perforation 7 with precast base 5 regularly on the surface, pass electric wire perforation 7 from underground cable and wire 13 and is connected with dry-type transformer 12 and relevant device thereof with steel frame 8, triangle hanging hole 14 fixings of service work pedal by triangle fastener 15 and steel frame 8 sides together.
The top of anchor bolt is welded with grounding anchor rod 6, and outer case foot bolt 1 regularly is arranged on the limit portion of reinforced concrete prefabricated base 5, and the outer case lower end and the weldering of the ground connection reinforcing bar in the precast base 54 of foot bolt 1 regularly is connected together.
The external lightning conducter 16 of transformer station, the earth connection 17 of transformer are connected ground connection by the ground connection reinforcing bar 4 in the precast base 5 and the support set bolt 2 at grounding anchor rod 6 tops respectively.
Embodiment
