Box-type substation and use method thereof

Abstract

The invention relates to the technical field of power transmission, and discloses a box-type substation and a use method thereof. The box-type substation comprises a foundation base, a shell is fixedly installed at the position, close to the outer side, of the top of the foundation base, and a separation device is fixedly installed at the position, located on the inner side of the shell, of the top of the foundation base. The size of the interval between a weight box and a trigger is the same as the thickness and the interval of the blades of a shutter I, shutters II and a shutter III, so that the weight box is in contact with the trigger and reaches the stroke limit, the shutters II on the two sides of the displaced mounting device can be exactly staggered with the shutters I on the two sides, so that the displaced mounting device and the mounting devices on the two sides are isolated from each other to achieve a flame-retardant effect, at the moment, no flow exists between the mounting devices, external gas cannot enter the mounting devices, the problem that external oxygen enters the interior to promote fire behavior is avoided, and the safety coefficient of the device is improved.

Description

technical field [0001] The invention relates to the technical field of electric power transportation, in particular to a box-type substation and a method for using the same. Background technique [0002] With the development of society and the progress of urbanization, the coverage of the power grid is also continuously deepening. In the urban power system, the box-type substation is one of the most widely used power equipment. The traditional phase-changing station will be directly installed in the community. Internally, the high-voltage power is stepped down and brought into the household to ensure the daily electricity demand of the residents. The box-type substation is mainly composed of high-voltage cabinets, high-voltage metering cabinets, transformers, low-voltage incoming cabinets, low-voltage outgoing cabinets and compensation cabinets. Facilities are often placed independently in separate cabins. In order to achieve the effect of flame retardancy, the interior of t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the existing box-type substation and its use method proposed in the background technology, the present invention provides a box-type substation, which has the advantages of lowering the temperature of the cabins inside the box-type substation at low cost and better performance. The advantage of the flame retardant effect solves the problem that the internal temperature of the traditional box-type substation is too high to achieve the purpose of flame retardancy and the transformation loss is too large
