Embodiment 1

[0051] like Figure 11 As shown, according to the present invention, the urban miniaturized prefabricated substation is installed between two utility poles.

[0052] The urban miniaturized prefabricated substation of the present invention is installed between utility poles 28, and the horizontal arm 29 is fixed approximately 2 to 2.5 meters away from the ground level. The type substation is hoisted as a whole, and is located on the installation cross arm 29, and the transformer and the channel steel at the bottom of the integrated intelligent distribution box are installed and fixed on the installation cross arm 29 through fasteners. The left side of the high-voltage switch cabinet is provided with a high-voltage incoming line bushing 2, which is connected with a high-voltage incoming line cable 5 and a high-voltage incoming line cable joint 4. The post-mounted installation of the miniaturized prefabricated substation for urban use is completed.

[0053] The overall working ...

Embodiment 2

[0074] like Figure 7-9 As shown, the structural schematic diagram of the frame shell in the urban miniaturized prefabricated substation of the present invention.

[0075]When the substation is installed on the ground, the substation is installed inside the frame shell 23. The frame shell includes an aluminum profile frame 24, a top plate 25 and a stainless steel door 26. The aluminum profile frame can be installed in a factory or on site, with great flexibility. The strength meets the IK anti-collision level required by the State Grid. It is light in weight, convenient for hoisting and transportation, and has high aesthetics. The plate is made of 201 stainless steel, which can achieve outdoor anti-rust effect. , The sealing level reaches IP23D, and it can achieve good heat dissipation effect without additional exhaust fan. According to user requirements, LED display screen 27 can be optionally installed on the back of the frame shell (such as Figure 10 Shown), can play the...

Abstract

The invention relates to a miniaturized preassembled substation for towns, which comprises a high-voltage switch cabinet (1), a distribution transformer (7) and a comprehensive intelligent distribution box (10), wherein the high-voltage switch cabinet (1) is installed on the distribution transformer (7); and the comprehensive intelligent distribution box (10) is located at the side surface of the distribution transformer (7) and the side surface of the high-voltage switch cabinet (1). The comprehensive intelligent distribution box (10) is of an integrated box structure, is detachably connected with the distribution transformer (10) into an integral structure through bolts, and has the characteristics of high integration level, convenient operation maintenance and small occupation area. The high-voltage switch cabinet (1) adopts gas box sealing, sulfur hexafluoride gas insulation and surface shielding, fully guarantees the personal safety and the operation safety of equipment, completes comprehensive functions of low voltage side power distribution and protection and the like through the comprehensive intelligent distribution box (10), and improves the power supply reliability and the power quality; selectively equipped distribution automation equipment and an intelligent perception terminal can realize intelligent management and state maintenance for the substation.

Description

technical field [0001] The invention relates to the technical field of power transmission, transformation and distribution of smart grids, in particular to a miniaturized prefabricated substation for urban use. Background technique [0002] In my country's distribution network, there are still a large number of pole-mounted switchgears. Especially in the urban 10kV distribution network, the substation system composed of high-voltage switches on the column, high-voltage drop-out fuses on the column, high-voltage surge arresters, transformers on the column, and low-voltage distribution boxes is the main power supply mode of the distribution network. In the prior art, there are many types of switchgear components on the pole, scattered distribution, low integration, inconvenient operation and maintenance, and the existing prefabricated substation occupies a large area and wastes resources. In addition, the equipment in the system Scattered on the high platform on the column, t...
