Low-voltage cabinet of box-type transformer station, and box-type transformer station with same

Abstract

The invention relates to a low-voltage cabinet of a box-type transformer station, and the box-type transformer station with same, wherein the low-voltage cabinet of the box-type transformer station comprises a wire inlet unit, a feeder line unit, a capacitance compensating unit and a secondary instrument unit. The wire inlet unit, the feeder line unit, the capacitance compensating unit and the secondary instrument unit are arranged in one cabinet body and furthermore are separated from one another through corresponding baffle plates. The wire inlet unit and the secondary instrument unit are parallelly arranged in the transverse direction of the cabinet body. The feeder line unit is arranged below the wire inlet unit and the secondary instrument unit. The capacitance compensating unit is arranged at one side of the wire inlet unit in the transverse direction, which deviates the secondary instrument unit, and furthermore the lower part of the capacitance compensating unit is arranged parallelly with the feeder line unit in the transverse direction. The wire inlet unit of the low-voltage cabinet is arranged at the middle part of the cabinet body in the transverse direction, thereby realizing convenient connection with other units. Furthermore the capacitance compensating unit and the feeder line unit can be distributed to relatively large spaces, thereby realizing reasonable layout and high space utilization rate. Furthermore, the units are arranged in a same cabinet body, thereby realizing benefit for assembling and maintenance, reducing detaching workload and improving operation efficiency.

Description

technical field [0001] The invention relates to a low-voltage cabinet of a box-type substation and a box-type substation. Background technique [0002] Box-type substation, referred to as box-type substation, is a compact power distribution equipment integrating high-voltage switchgear, distribution transformer and low-voltage power distribution device. It organically combines functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution. Together, they are installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed steel structure box, suitable for cities, rural areas, industrial and mining enterprises, public building facilities, oil and gas fields and wind power stations, etc. In many fields, it can replace the original civil power distribution room and substation, and become a new type of complete power transformation and distribution device, with small footprint,...

AI Technical Summary

Problems solved by technology

The low-voltage cabinet in the box-type substation with the above structure has the following defects in the actual use process: 1) When designing the cabinet, the installation of various components in the cabinet is considered separately, and the space in a single cabinet cannot be fully utilized. Low, which increases the area occupied by the overall space, and the corresponding box transformer should also consider increasing the space and floor area; 2) The cabinets need to be connected during assembly, and the cabinets need to be separated for maintenance. The workload of the workers is heavy, the labor intensity is high, the assembly and maintenance are inconvenient, the work efficiency is low, and it is not easy to guarantee the work quality
