Intelligent vehicle-mounted mobile transformer substation

Abstract

The invention belongs to the technical field of substation equipment, and particularly relates to an intelligent vehicle-mounted mobile transformer substation. The transformer substation comprises a power transformation vehicle and a power distribution vehicle connected with the power transformation vehicle, and the power transformation vehicle comprises a power transformation vehicle body, an HGIS and a main transformer, and the HGIS is installed on the vehicle body; the power distribution vehicle comprises a power distribution vehicle body, a prefabricated cabin, an electrical secondary protection chamber and a medium-voltage power distribution chamber; a control cubicle is arranged on the HGIS of the power transformation vehicle; the control cubicle is provided with an in-situ protection and measurement and control device sub-machine I; the instrument terminal box is provided with an in-situ protection and measurement and control device sub-machine II; and a medium-voltage switch cabinet in the medium-voltage power distribution room is provided with an in-situ protection and measurement and control device sub-machine III, a measurement and control device sub-machine IV, a measurement and control device sub-machine V, a measurement and control device sub-machine VI and a measurement and control device sub-machine VII. The number of cables and the number of screen cabinets between two vehicles are effectively reduced, products are highly integrated, the transportation size is reduced, safety and reliability are achieved, field installation is easy, and the intelligence andreliability of the products are improved.

Description

technical field [0001] The invention belongs to the technical field of substation equipment, and in particular relates to an intelligent vehicle-mounted mobile substation. Background technique [0002] Along with the needs of social and economic development, the society has stricter requirements on the power supply system, and traditional power solutions have been continuously improved and supplemented. As a supplement to the fixed substation, the vehicle-mounted mobile substation has the characteristics of flexibility, low cost, etc., and effectively solves the power supply problem in the case of power equipment maintenance or substation transformation, load transfer, temporary power consumption for new construction, and emergency power consumption. . However, the existing vehicle-mounted mobile substation still needs to be improved in terms of intelligence, transportation size, on-site installation, and reliability guarantee.

Problems solved by technology

However, the existing vehicle-mounted mobile substation still needs to be improved in terms of intelligence, transportation size, on-site installation, and reliability assurance.

[0003] The vehicle-mounted mobile substation technology in the prior art has a low degree of intelligence. It adopts the traditional method of protection, measurement and control centralized screen grouping. A large number of connecting control cables are used between the two vehicles. The cable tray for receiving the connecting cables increases the length of the vehicle board. The on-site connection workload is heavy, and there are technical problems such as the risk of CT open circuit and low intelligence in the aviation plug of the connecting cable.
