Abstract

The utility model relates to an outdoor box type transforming box. The utility model is characterized in that a high-voltage distribution part, a low-voltage distribution part, an electric energy metering device, etc. which are functional parts are combined into a shape like a Chinese character 'pin', and form a set of a distribution device; high-voltage protection adopts a load switch with a pull-out type fuse; the low-voltage distribution part, the electric energy metering part, and the capacitance compensation part adopt a comprehensive integrated module structure of a functional unit of a fixed partition type, a pull-out type, and a drawer type, and the arrangement of the in-out wire of a power transformer is changed into a side in-out wire type; a big cover of an oil tank adopts a fully sealed and welded structure, meeting the requirement of full sealing and no need of maintenance.

Description

The box power transformation case of outdoor type

The utility model belongs to a kind of electric power and becomes power distribution equipment, is mainly used in outdoor high-voltage to be become low pressure and be distributed in the transformation and distribution system of a plurality of low-voltage distribution circuit to use.

The box power transformation device of present domestic outdoor type adopts that high voltage power distribution part, power transformer, low-voltage distribution part are assembled in the separated casing composition " order " font structure respectively is more, so structural volume is big, the transformer radiating condition is poor, temperature rise in the whole box body, particularly low pressure divides circuit switching to adopt fixed installation, in case switch need be changed in certain branch loop, the total loop that then need have a power failure has enlarged the power failure area.Therefore, need do structural improvement.

The purpose of this utility model is to propose a kind of compact conformation, good heat dissipation effect, non-maintaining at the deficiency of the existing box power transformation case of outdoor type, particularly each low pressure divides the loop independent, the box transformation device of novel outdoor type that does not need total loop to have a power failure when any low tension loop is broken down.

According to the technology implementation scheme that the purpose of this utility model proposed be: functional parts such as high voltage power distribution, power transformer, low-voltage distribution part and electric power meter are combined as one " product " font profile structure, and form complete power distribution equipment.High voltage protective is selected the on-load switch of band pull-out type fuse for use; low-voltage distribution, electric energy metrical and capacitance compensation then adopt the fixedly comprehensive integrated modular structure of cellular-type, pull-out type or drawer type functional unit; and power transformer turnover line is arranged the side turnover line style formula that changes into; the big lid of fuel tank adopts hermetic Welding Structure, to reach the requirement of full sealed non-maintenance.

The utility model is owing to adopting the compact complete distribution form of " product " font and having carried out high voltage power distribution, low-voltage distribution, electric energy metrical and capacitance compensation modular construction; and select pull-out type, drawer type, pull-out type respectively for use, fixedly the functional module of cellular-type is intersected to cooperate and is combined, and has that defencive function is strong, reliable, volume is little, overall performance good, interchangeability is strong, be convenient to maintenance.Be applicable in change, the distribution sections such as city net power supply, biotope, hotel, market, post and telecommunications, recreation center, capital construction installation to have great application value.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the utility model overall structural arrangement figure;

Fig. 2 is the utility model low-voltage distribution part composition diagram;

Fig. 3 is the turnover line layout plan of the utility model power transformer.

The utility model comprises high voltage power distribution part 1, low-voltage distribution part 2, power transformer more than 3 parts as can be seen from accompanying drawing, it is characterized in that: high voltage power distribution part 1 of the present utility model, low-voltage distribution part 2 and power transformer 3 are " product " font and arrange, power transformer 3 is outside high and low voltage electric distribution part casing 4, and the turnover line of power transformer 3 is a side turnover layout, and inlet wire 10 and outlet 11 are introduced the high and low voltage electric distribution parts by power transformer and high and low voltage electric distribution part connecting plate 5.For the aspect operating maintenance, it is drawer-type structure that the utility model has also adopted the low pressure in the low-voltage distribution part 2 to go out line loop 6, and but each low pressure goes out the modular construction of line loop 6 for the independent operation maintenance, and electric power meter 7 and electric capacity control device 12 are the cellular-type module structure, but low pressure total loop 8 and compensating capacitor device 9 are again the pull-out type functional module elements, whole low-voltage distribution part 2 is a functional unit modularization integral structure, in order to make power transformer 3 reach the function of full sealed non-maintenance, the utility model also adopts hermetic Welding Structure with the big lid of fuel tank of power transformer 3.

Box power transformation case of the present utility model is strengthened on transformer internal process structure in overall structural arrangement design, it is non-maintaining that the big lid of fuel tank takes to weld hermetically sealed implementation, design in the side into and out of line into and out of line end, three faces are provided with the corrugated plating radiator, and be installed on outside the casing, radiating condition is good.High voltage power distribution partly adopts on-load switch operation and the protection with movable safety fuse, and is provided with lightning arrester and high-tension electricity indicating device.The low-voltage distribution part, its low pressure divides circuit control device to adopt drawer-type structure, compensation condenser chamber and low total loop control dress show employing pull-out type structure, the cellular-type structure is adopted in electric energy metrical chamber and electric capacity control room, and be provided with service chamber, insulating power supply, maintenance lamp etc. are arranged in the case, and overall structure adopts the modularization suit, has stronger interchangeability.The drawout cubicle structure is provided with interlock simultaneously, has avoided misoperation, in case the normal power supply that does not influence other loop need be overhauled in certain branch loop.

For operate as normal, be provided with and make an inspection tour illumination, electric current, voltage indication in the power transformation case.Capacitance compensation is pressed customer requirements and is selected.The body structure degree of protection is not less than IP3, and the high and low pressure electric elements are selected all to meet international requirement, is at present domestic unique box power transformation case, is a kind of comparatively desirable high and low voltage electric distribution partial update regeneration product.
