New Transformer Installations for Substations

Abstract

The invention discloses a novel transformer device for a substation, which improves the heat dissipation effect and prevents rainwater from intruding into the interior of a box. The novel transformerdevice also provides a reliable shock absorbing structure, so that the vibration of a transformer body is reliably reduced, and vibration damage is reduced. The novel transformer device comprises a box body and a transformer body disposed in the box body; the top of the box body has a box cover; air inlets are formed in positions near the bottoms of side surfaces of the box body; air inlet assemblies are installed on the air inlets; exhaust ports are formed in the box cover; exhaust assemblies are arranged on the exhaust ports; the air inlets and the exhaust ports communicate with the interiorof the box body; base assemblies are arranged on a ground inside the box body; the transformer body is fixedly arranged on the base assemblies; fixing pedestals are arranged on the bottom of the transformer body; and each fixing pedestal is corresponding to one base assembly.

Description

Technical field [0001] The invention relates to a transformer device, in particular to a box type transformer including a box body and a transformer body. Background technique [0002] At present, in the field of power transmission and transformation, the most commonly used transformer type is the box-type transformer, which includes a box body, the transformer body is organized inside the box body, and the box body provides protection, installation and heat dissipation functions; specifically, shutters or convection are provided on the box body Holes are used to realize the heat dissipation function. A raft board and other prefabricated foundations are installed inside the box to fix the transformer body. After long-term use, we found that the design efficiency of convection holes in the existing box is very low, and the heat inside the box rises. It is concentrated on the top, and the convection holes opened on the side of the box are difficult to completely replace the interna...

Problems solved by technology

[0002] At present, in the field of power transmission and transformation, the most used type of transformer is a box-type transformer, which includes a box body, which organizes the transformer body inside, and the box body provides protection, installation and heat dissipation functions; specifically, the box body is equipped with shutters or convection Holes are used to realize the heat dissipation function, and prefabricated foundations such as rafts are set inside the box to fix the transformer body; after a long period of use, we found that the design efficiency of the existing convection holes in the box is very low, and the heat inside the box rises evenly. Concentrated on the top, the convection holes set on the side of the box are difficult to completely replace the internal hot air; if the heat dissipation holes are opened on the box cover on the top of the box, although the hot air can be discharged quickly, a large part of the box-type transformers are set in Outdoors, this structure greatly increases the possibility of internal water ingress, causing damage to the device;

[0003] In addition, the transformer device will vibrate when it is in use. The vibration is currently realized by the shock-absorbing rubber installed at the bottom. However, after our research, we found that the vibration direction is not only the vertical vibration, but also the horizontal vibration. Setting shock-absorbing rubber at the bottom will cause the vibration in the horizontal direction to not be suppressed, and the vibration damage will increase over time, causing the transformer to fail to work normally

[0004] Finally, whether it is an indoor or outdoor box-type transformer, the opening of the heat dissipation holes will cause an increase in internal noise and airflow noise, which will affect the work and life of people in the installation location; only by controlling noise can the popularity of box-type transformers go further , the scope of application will be greatly increased
