Abstract

The application discloses a compact box-type transformer substation, which comprises a box body, wherein an installation space is formed in the box body, an oil tank is arranged in the middle of the installation space, a high-pressure chamber is arranged on the high-pressure side of the oil tank, a low-pressure chamber and an operation chamber are arranged on the low-pressure side of the oil tank, a circuit breaker and a transformer are arranged in the longitudinal direction in the high-pressure chamber, and the low-pressure chamber and the operation chamber are arranged in parallel in the transverse direction. The high-voltage chambers are distributed along the longitudinal extension of the high-voltage side of the oil tank, so that high-voltage equipment such as a circuit breaker and a transformer form a longitudinal equipment belt vertical to the ground in a three-dimensional space, the axial arrangement not only compresses the transverse occupied space of the high-voltage equipment, but also deconstructs the high-voltage cabinet body with traditional planar arrangement into a three-dimensional integrated module through longitudinal lamination type installation, and the connecting path of the high-voltage conductor is shortened.

Description

Compact box-type transformer substation Technical Field The application relates to the technical field of power equipment, in particular to a compact box-type transformer substation. Background The existing box transformer equipment in the current market is various in variety, the high and low levels of products are different, and along with the integral development of new energy power system complete equipment industry in recent years and the continuous demands of the market, the structural design concept of the ring main unit equipment is insufficient to meet the current market requirements. In order to meet the continuously improved demands of users and standardize product design, the vitality of box-type transformer substation products is improved, the upgrading and the updating of the products are made, and the product level of the box-type transformer substation is comprehensively improved aiming at the continuously emerging new technology and new technology in the current market so as to meet the rapidly developed market demands. The box transformer in the related art needs dual fixed knot structure, high-voltage equipment and box, and high-voltage equipment is longer with the transformer connection interval, leads to the box lateral dimension to be forced to expand, and the breaker switch is installed in independent high-voltage cabinet simultaneously, then hoists to the box transformer shell in, need compromise the fixed, transformer and the high-voltage connection interval length of high-voltage cabinet and box transformer, and then makes the big area of whole box volume big to lead to the cost of transportation high. Therefore, a box transformer structure with compact depth is needed to solve the core problems of large occupied area and low space efficiency of the box transformer in the related technology, and meet the urgent requirements of a novel power system on high-density distribution nodes. Disclosure of utility model The application aims to provide a compact box-type substation so as to solve the problem of large occupied area of a box-type substation. In order to achieve the purpose, the technical scheme includes that the compact box-type transformer substation comprises a box body, an oil tank and an oil tank, wherein an installation space is arranged in the box body, the oil tank is arranged in the middle of the installation space, a high-pressure chamber is arranged on the high-pressure side of the oil tank, a low-pressure chamber and an operation chamber are arranged on the low-pressure side of the oil tank, a circuit breaker and a mutual inductor are arranged in the longitudinal direction of the high-pressure chamber, and the low-pressure chamber and the operation chamber are arranged in parallel in the transverse direction.
