A functional bay of a containerized substation

Abstract

The invention provides a functional space for a container type transformer substation. The functional space comprises a bus connecting device, and is characterized by further comprising a tank body for containing the bus connecting device, wherein the bus connecting device can be fixed in the tank body due to the arrangement of the tank body, and the functional space can be mounted in an international standard container, a main bus is horizontally arranged above the rear part of the tank body, the bus is supported by a wall bushing; a fixed contact, a mutual inductor and a grounded switch arranged at the rear part of the tank body are further arranged in the functional space, a disposable cable is arranged at the lower part of the tank body, and a secondary instrument terminal chamber and a secondary cable type wiring duct are arranged on the front part of the tank body. The spaces of the transformer substation can be well mounted in different functional spaces, and the functional spaces can be mounted in the international standard container, and therefore, the transformer substation can achieve the purposes of prefabrication, low manufacturing cost, safety, reliability and convenient transportation.

Description

technical field [0001] The invention relates to a functional compartment of a containerized substation in the technical field of electric power engineering, in particular to a functional compartment of a containerized substation with a voltage level of 40.5kV. Background technique [0002] In the power system, a substation is composed of closely connected parts with some common functions, such as: switchgear between incoming or outgoing lines; bus connection equipment composed of circuit breakers and interval switches; transformers and two Switchgear between buses of different classes. These sections are called bays, and the identification of these bays is important for maintenance or expansion planning. [0003] The building parts involved in the traditional substation are all made of concrete structure and steel structure, but there are many shortcomings in the middle interval of this traditional substation, such as: large space occupation, large equipment size, long manu...

AI Technical Summary

Problems solved by technology

[0003] The building parts involved in the traditional substation are all made of concrete structure and steel structure, but there are many shortcomings in the middle interval of this traditional substation, such as: large space occupation, large equipment size, long manufacturing cycle; and the interval of traditional substation Generally, SF6 inflatable cabinets are used. This kind of inflatable cabinets still has high manufacturing costs, especially in foreign countries, such as Europe, and an emission tax of US$750 / kg will be imposed on greenhouse gases.

Moreover, the intervals between substations in the prior art are inconvenient for transportation and difficult for construction.
