Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The high-voltage and medium-voltage electrical equipment connection method provided by the present invention realizes direct connection of electrical equipment to each other by adjusting the spatial position of the lead-out bushings of the electrical equipment, and the adjusted lead-out bushings of the electrical equipment are on different spatial planes. The same-phase outlet bushings between different devices are all on the same space level, and the distance between the phase outlets connected to the same-phase outlet bushings maintains a corresponding electrical insulation level, so as to ...

Abstract

Disclosed is a connection mode of high and medium-voltage electrical devices. Same-phase outlet wire sleeves of different electrical devices are directly connected through respective phase outlet wires, respective lead-out sleeves of the electrical devices are respectively disposed at different space planes, the same-phase outlet wire sleeves, which are directly connected, between the different electrical devices are disposed at the same space horizontal plane, and the distances formed by connecting the respective phase outlet wires of the same-phase outlet wire sleeves maintain corresponding electrical insulation level. According to the connection mode brought forward by the invention, first of all, since bus support, insulation and fixation devices and the like in a transformer station are omitted, the cost is reduced and bus insulation breakdown faults and various faults caused by bus connection heating are avoided; secondly, since the connection mode is applied to indoor arrangement, upper-portion space of equipment is saved, the height of the building is reduced, and the cost is decreased; and finally, the installation workload is reduced, high-altitude operation, in particular, is omitted, and the risk of high-altitude installation operation is reduced.

Description

technical field [0001] The invention relates to a connection mode of electrical equipment, in particular to a connection mode of high and medium voltage electrical equipment. Background technique [0002] In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of power, and adjusts voltage. It connects the power grids of all levels of voltage through its transformers, and is the gathering point for power transmission and distribution. A substation is an assembly of some equipment to cut or connect, change or adjust voltage. [0003] In the prior art, electrical equipment is connected through busbars, which requires busbar s...
