Abstract

The utility model discloses a flame-proof dry transformer for mine, comprising a box wall (1). The box wall is a corrugated plate (2), and at least a reinforcing rib (3) is arranged in the corrugated slot of the corrugated plate (2). The design and structure of the reinforcing corrugated box wall of the flame-proof dry transformer for mine can solve the pressure problem that a box body bears 1 Mpa static pressure according to G B 3836-2000 standard requirements. The utility model is a flame-proof dry transformer for mine with timely diffused temperature for a transformer in the box body, high mechanical strength of the box wall, simple structure, convenient production and low cost.

Description

Flameproof dry type transformer

Technical field

The utility model relates to a kind of dry-type transformer, particularly relates to a kind of flameproof dry type transformer.

Background technology

Flameproof dry type transformer is a kind ofly to be applicable to methane blended gas and coal dust and to have in the mine of explosion hazard, as the controller switching equipment of comprehensive mechanization extractive equipment under the coal mine.The level of manufacturing of its shell requires very high, should guarantee that transformer can dispel the heat well, guarantees again to bear internal explosion power by the GB3836-2000 standard.The tank wall of flameproof dry type transformer adopts pure wave card structure at present, is difficult to bear by the GB3836-2000 standard-required pressure, particularly products with larger capacity of static pressure 1Mpa.

The utility model content

Technical problem to be solved in the utility model provides the flameproof dry type transformer that the transformer temperature rise can in time leave, the tank wall mechanical strength is high in a kind of casing.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flameproof dry type transformer, comprise tank wall, and described tank wall is a corrugated plating, is provided with a reinforcement in the wave trough of described corrugated plating at least.

Adopt the flameproof dry type transformer of technique scheme, corrugated plating is by the ripple mold forming, with dull and stereotyped tank wall ratio, increased and the air contact area, promptly increased area of dissipation, guaranteed that the transformer temperature rise in time leaves in the casing, reinforcement adopts steel plate to process, for solid, like bellows-shaped, by with the integral body that is welded into of corrugated plating, strengthened the mechanical strength of tank wall greatly, guaranteed the fail safe that product uses under coal mine, seen the same from appearance with the tank wall bellows-shaped.

In sum, the utility model is the flameproof dry type transformer that the transformer temperature rise can in time leave, the tank wall mechanical strength is high and simple in structure, easily manufactured, with low cost in a kind of casing.

Fig. 2 is along A--A line cutaway view among Fig. 1;

Fig. 3 is an I place enlarged drawing among Fig. 2.

Embodiment

Following structure the drawings and specific embodiments are described in further detail the utility model.

Referring to Fig. 1, Fig. 2 and Fig. 3, tank wall 1 is a corrugated plating 2, and proportional spacing is provided with reinforcement 3 in the wave trough of corrugated plating 2.Corrugated plating 2 adopts the Q235A steel plate by the ripple mold forming, with dull and stereotyped tank wall ratio, increased and the air contact area, promptly increased area of dissipation, guaranteed that the transformer temperature rise in time leaves in the casing, reinforcement 3 (being commonly called as the false wave line) adopts the Q235A steel plate to process, for solid, like bellows-shaped, by with the integral body that is welded into of corrugated plating 2, strengthened the mechanical strength of tank wall greatly, guaranteed the fail safe that product uses under coal mine, seen the same from appearance with the tank wall bellows-shaped.

The project organization of the reinforced ripple tank wall of flameproof dry type transformer, having solved the stress problems of bearing static pressure 1Mpa by GB3836-2000 standard-required casing well, is the flameproof dry type transformer that the transformer temperature rise can in time leave, the tank wall mechanical strength is high and simple in structure, easily manufactured, with low cost in a kind of casing.

Claims

A kind of flameproof dry type transformer comprises tank wall (1), it is characterized in that: described tank wall is corrugated plating (2), is provided with a reinforcement (3) in the wave trough of described corrugated plating (2) at least.
