Abstract

The utility model discloses a box-type transformer which comprises a box body and partition boards, wherein the box body is divided into three mutually independent spaces by the partition boards, and the partition boards are aluminum-plated zinc steel plates or aluminum-coated zinc steel plates. The transformer box of the box-type transformer is divided into three mutually independent spaces, wherein the three mutually independent spaces of the box body are a high-voltage chamber, a transformer chamber and a low-voltage control chamber, so that equipment with different functions are installed separately, thereby avoiding mutual inferences. Furthermore, the three spaces are separated by the insulating partition boards, thereby protecting the safety of operating personnel in the control chamber. Meanwhile, the aluminum-plated zinc steel plates or the aluminum-coated zinc steel plates have high strength and good corrosion resistance, thereby being capable of adapting to hostile environments.

Description

Box type transformer

Technical field

The utility model relates to the power transmission and transformation technical field, particularly a kind of box type transformer.

Background technology

Along with the continuous fast development of market economy, the distribution system industry with more and more faster speed in development, box-type substation with it economy, reliable, be suitable for and accepted by users gradually, its application is also more and more.Use now maximum high/low voltage pre-installed type box-type substations that belong on the market.The inherent structure of box-type substation is at present, and box-type substation (hereinafter to be referred as box change) is mainly by the high and low voltage electric distribution device, and transformer and casing three parts are formed.Tank material divides metal and nonmetal two kinds, metal material to be meant that casing selects steel plate for use, and bendings such as aluminium sheet are welded, and are characterized in that mechanical strength is high, and heat-resisting compressive property is good, but that its inherent defect is a heat-insulating property is poor.Along with raw material on the GB, price advance-go on foot raising, oneself sharp rises the price of the metal material that uses, therefore pressing for a kind of new material replaces it.Another kind is nonmetallic materials, and at present the nonmetallic materials that become of case are stopped into the glass fiber cement case, are characterized in that mechanical strength is high, heat-resisting resistance to compression, and ultra-violet radiation resisting, the anti-performance of tanning by the sun is good, has protection against the tide, antifreeze, anticracking, characteristics such as anti-flaming, anticorrosive.But it also has inherent defect to be exactly; Owing to used a large amount of cement, self is too heavy, and has still selected for use steel plate as dividing plate between its three compartments; Temperature owing to transformer in the transformer room is higher; And higher with steel plate as its heat conductivility of dividing plate, just be easy to the temperature conduction in the transformer room in high and low voltage chamber, thereby be prone to cause the temperature in the whole box change higher.

The utility model content

The utility model provides a kind of box type transformer rational in infrastructure.

For solving the problems of the technologies described above, the utility model box type transformer comprises: casing; Dividing plate, said casing is divided into three relatively independent spaces through said dividing plate with said casing.Said dividing plate is plating or aluminizing zine plate.

The utility model box type transformer is divided into three separate spaces with the power transformation case; Casing is divided into: the hyperbaric chamber; Transformation chamber and low voltage control chamber so are installed separately the equipment of difference in functionality well, have avoided interference each other; And with the dividing plate that insulate separately, protected the operating personnel's in the control room safety with three spaces.Plating or aluminizing zine plate have very high intensity and good corrosion resistance simultaneously, can adapt to rugged environment.

Description of reference numerals in the utility model box type transformer accompanying drawing:

4-low voltage control chamber, 3-transformation chamber, 1-dividing plate 2-hyperbaric chamber.

Embodiment

Below in conjunction with accompanying drawing the utility model box type transformer is done further explain.

As shown in Figure 1, the utility model box type transformer comprises: casing, casing are that dividing plate is that the plating or the dividing plate 1 of aluminizing zine plate are divided into three relatively independent hyperbaric chambers 2 with casing, transformation chamber 3 and low voltage control chamber 4 through material.

The preferred embodiment of below the utility model having been created specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.

Claims

1. box type transformer is characterized in that, comprising:

Casing;

Dividing plate, said casing is divided into three relatively independent spaces through said dividing plate with said casing.

2. box type transformer according to claim 1 is characterized in that, said dividing plate is plating or aluminizing zine plate.
