Prefabricated transformer substation with protective device

Abstract

The invention provides a prefabricated substation with a protective device, which comprises a box body, a roof and a box door, the inner side of the roof is provided with an inner cavity, the inner sides of the box body and the box door are welded with partition plates, the inner side of the box body is provided with a transformer, the top and the bottom of the transformer are welded with support columns, and the support columns are welded with the protective device. Clamping sleeves are welded to the top and the bottom of the box body, first springs sleeve the outer sides of the supporting columns, an air duct is welded to the top of the box body, and a first draught fan is installed on the inner side of the air duct through bolts. According to the prefabricated substation with the protection device, the heat dissipation efficiency in cloudy and rainy days can be guaranteed, water is prevented from entering the box body, and the service life of the prefabricated substation is prolonged. Heat dissipation safety of a transformer is guaranteed, noise is greatly attenuated in the box body, noise is prevented from being transmitted out, quiet work of a transformer station is guaranteed, life of surrounding personnel is facilitated, moisture and dust on the net belt are blown off, air permeability of the net belt is guaranteed, heat dissipation efficiency is guaranteed, and the box is suitable for voltage conversion and power transmission.

[0002] The prefabricated substation equipment is to install the manufactured substations at the required positions, and electrically connect them to the busbar or cables to perform voltage conversion. It is also called box-type substation or prefabricated substation. Power station, the existing prefabricated substation equipment basically prefabricated substation has the advantages of small size, less land occupation, light weight, low cost, high reliability, high work safety, easy installation and maintenance, long service life, etc. , can meet the power supply needs of residential quarters, urban public substations, bustling downtown areas, urban residential areas, urban public power distribution, street light power distribution, industrial and mining, etc. However, for the existing prefabricated substation equipment, on the one hand, When working, it cannot effectively guarantee the heat dissipation safety in rainy days. In rainy days, it is easy to cause moisture to enter the inner side of the prefabricated substation through the heat dissipation channel, which is not conducive to ensuring the heat dissipation safety of the prefabricated substation equipment. On the other hand, When working, it is easy to generate a certain amount of noise, which is easy to cause noise pollution, and then it is easy to affect the lives of people around, which is not conducive to effectively reducing the generation of noise. On the other hand, when performing heat dissipation operations, in order to prevent the entry of dust, It is necessary to use a filter mechanism to filter the air, which will easily cause the filter mechanism to be blocked by air impurities, which is not conducive to ensuring the heat dissipation efficiency
