Problems solved by technology

It often leads to frequent maintenance and power outages, which affects the happiness index of urban residents and the image and service quality of power supply companies
[0003] The current situation that the exhaust and heat dissipation system of the transformer in the existing box-type transformer does not have a significant effect. The bottom plate of the transformer room is often in the form of a welded bare plate, resulting in poor air convection, and often the heat of the transformer cannot be well discharged by the exhaust fan.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] Such as Figure 1-3 As shown, a box-type transformer room heat dissipation system includes a transformer room 1 and a low-voltage room 2. The high-low voltage room 2 is connected to the transformer room 1. The dividing plate 3 is provided with a square opening 4, and the opening 4 can also be circular, rectangular and other shapes; the area of ​​the square hole opening is 20cm*20cm, and the thickness of the square hole is 3mm, and the area is 23cm* 23cm insulating plate is blocked, and a round hole with a diameter of 16cm is punched on the insulating plate to increase the airflow exchange between transformer room 1 and low-voltage room 2 and the fan effect, so that the whole box-type transformer room can dissipate heat better; the bottom of transformer room 1 The end bottom plate 5 is a barbed wire mesh, and the bottom plate is replaced by a barbed wire mesh to ...

Abstract

The invention discloses a box-type transformer room heat-dissipation system, and the system comprises a transformer room and a low-voltage chamber connected with the transformer room. A low-voltage chamber partitioning plate is disposed between the transformer room and the lower-voltage chamber, and is provided with an opening. A bottom plate at the bottom end of the transformer room is an iron gauze. Compared with the prior art, the system enables a bottom plate of the transformer room to be replaced by the iron gauze, and improves the heat discharge effect of a transformer in the transformer room. The low-voltage chamber partitioning plate is provided with the opening, and an insulating plate which blocks the opening is provided with a circular hole, so as to improve the air flow exchange between the transformer room and the lower-voltage chamber and the effect of a ventilator, and enable the whole box-type transformer room to be better in heat-dissipation effect. The system is simple in design, and is convenient to install.

Description

technical field [0001] The invention relates to the field of box-type substations, in particular to a cooling system for a box-type transformer room. Background technique [0002] 10KV outdoor European-style transformers have been widely promoted and used in residential quarters, urban public transformers, and bustling downtown areas because of their compact structure, small size, simple layout, convenient installation, beautiful appearance, and easy coordination with the urban environment. . A large number of operating practices have proved that most of the European-style box-type substation equipment that has been put into operation in the current urban grid is particularly prominent in power outages due to equipment overheating during peak load periods in summer. It often leads to frequent maintenance and power outages, which affects the happiness index of urban residents and the image and service quality of power supply companies. [0003] The current situation that th...
