Abstract
The utility model relates to a technical field of box-type transformation equipment, in particular to an extendable door for a box-type transformer, which is mounted in a door opening of the box-type transformer and is characterized in that a door consists of an outer-layer door, a middle-layer door and an inner-layer door, wherein one side of the outer-layer door is connected with one side of the door opening, one side molding of the middle-layer door is sleeved into the outer-layer door from the other side of the outer-layer door, one side molding of the inner layer door is sleeved into the middle-layer door from the other side of the middle-layer door, and sliding tracks are embedded in both the upper and the lower sides of the outer-layer door, the middle-layer door and the inner-layer door. The extendable door mainly solves the technical problem that a door structure of the prior European-type box-type transformer has a large and heavy volume, and the extendable door is easy to open or close.
Description
Technical field
The utility model relates to box converting equipment technical field, and particularly a kind of case becomes retractable door.
Background technology
Box-type substation (be called for short: case becomes) is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, the prefabrication of lining up one by certain connection plan is indoor, outdoor close-coupled controller switching equipment, be about to high powered, the transformer step-down, functions such as low-voltage distribution are organically combined, be installed in a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the steel construction casing, electromechanical integration, totally-enclosed operation, being specially adapted to city net construction and upgrading, is a kind of brand-new transformer station that emerges after civil engineering transformer station.
In addition, box-type substation is a kind of the high voltage switchgear distribution transformer, low voltage switchgear, and electric energy measuring equipment and reactive power compensator etc. are combined in the complete power distribution equipment of compact in one or several casing by certain connection plan.It is applicable in the rated voltage 10/0.4KV three-phase alternating current system, as the usefulness of circuit and distribution electric energy.Be applicable to places such as factory, mine, oil field, harbour, airport, city public building, residential quarter, highway, underground installation.According to the difference of product structure difference and employing components and parts, be divided into European case change and American case and become two kinds of typical styles.
China is from the later stage seventies, introduce and imitated box-type substation from states such as France, Germany, adopt the high and low pressure switch cubicle from structure, transformer is formed mode, this case becomes and is called European case and becomes, image liken to high and low pressure switch cubicle, transformer cover the house.
The door that existing European case becomes as shown in Figure 1, it is to be connected whole fan 1 structure on the door opening by hinge 2 structures.Because it is generally all bigger that European case becomes its volume, corresponding door is also huger and heavy, gives and uses (particularly opening and closing operation) to bring inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of cabinet of low-tension switch cabinet, mainly solves the bulky and heavy technical problem of door in the door that has European case change now, and the door that case is become can easily open or close.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of case becomes retractable door, and it is installed in the door opening of case change, it is characterized in that: every fan door is made of outer door, middle level door and inner layer door; Wherein, outer door one side is connected door opening one side, and door one side embedding in middle level is inserted in the outer door from outer door opposite side; Inner layer door one side embedding is inserted in the middle level door from middle level door opposite side; This skin door, middle level door and the upper and lower both sides of inner layer door all are embedded in dragging track.
Described case becomes retractable door, it is characterized in that: on this inner layer door door lock is installed.
By said structure, the utlity model has following advantage:
The utlity model has slidably and nested successively outer door, middle level door and inner layer door, during use, outer door, middle level door and inner layer door all can slide in dragging track, and inner layer door can be nested in the door of middle level, and the middle level door can be nested in the outer door.Compare with a door structure bulky and heaviness in the door that original European case becomes, the operation of opening the door and closing the door is more laborsaving.
Description of drawings
Fig. 1 is existing European box type substation door structural representation.
Fig. 2 is a Facad structure schematic diagram of the present utility model.
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
See also Fig. 2,2, it is the structural representation that a kind of case of the utility model becomes retractable door.As shown in the figure: it is installed in the door opening of case change, and every fan door is made of outer door 10, middle level door 20 and inner layer door 30; Wherein, outer door 10 1 sides are connected door opening one side, and door 20 1 side embeddings in middle level are inserted in the outer door 10 from outer door 10 opposite sides; Inner layer door 30 1 side embeddings are inserted in middle level door 20 from middle level door 20 opposite sides; This skin door 10, middle level door 20 and inner layer door 30 upper and lower both sides all are embedded in dragging track 40.On this inner layer door 30 door lock 50 is installed.
During use, outer door 10, middle level door 20 and inner layer door 30 all can slide in dragging track 40, and inner layer door 30 can be nested in the middle level door 20, and middle level door 20 can be nested in outer 10.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
Claims (2)
1, a kind of case becomes retractable door, and it is installed in the door opening of case change, it is characterized in that: every fan door is made of outer door (10), middle level door (20) and inner layer door (30); Wherein, outer door (10) one sides are connected door opening one side, and door (20) one side embeddings in middle level are inserted in the outer door (10) from outer door (10) opposite side; Inner layer door (30) one side embeddings are inserted in middle level door (20) from middle level door (20) opposite side; This skin door (10), middle level door (20) and the upper and lower both sides of inner layer door (30) all are embedded in dragging track (40).
