An apparatus for securing a transformer that includes a mounting bracket coupled to an exterior surface of the transformer, the mounting bracket having a first length, a first height, and a first width to define a mounting bracket having an interior cavity includes a housing having a second length, a second height, and a second width to define an interior cavity with at least one interior surface. The second length is larger than the first length of the mounting bracket and the second width is larger than the first width such that the mounting bracket is receivable into the interior cavity. A shaft member extends from the at least one interior surface along the second length within the housing interior cavity. The shaft member receives a securing strap around at least a portion of the shaft member within the mounting bracket to secure the transformer to the apparatus.

The present invention belongs to the technical field of mobile transformer substation, and in particular relates to a vehicle-mounted mobile transformer with a position-adjustable lead-out bushing. In view of the shortage that, when the existing conventional transformer is applied to a vehicle-mounted mobile transformer substation, the transportation dimension exceeds the regulated width, height and limit, the present invention adopts the following technical solution: a vehicle-mounted mobile transformer with a position-adjustable lead-out bushing, comprising: a transformer body; and a high-voltage lead-out bushing, the high-voltage lead-out bushing comprising an oil-SF6 gas bushing, an SF6 gas-air bushing and a connecting device, the oil-SF6 gas bushing being mounted on a high-voltage bushing base, the connecting device being mounted on the oil-SF6 gas bushing, the SF6 gas-air bushing being mounted on the connecting device, and the SF6 gas-air bushing being rotatable relative to the connecting device such that the position of the SF6 gas-air bushing is adjustable. The present invention has the beneficial effects that the SF6 gas-air bushing is rotatable, the position is adjustable and thus the transportation requirement of high-voltage (such as 220 kV) equipment is met.

A reactor includes a core body, and the core body includes an outer peripheral iron core, at least three iron cores in contact with an inner surface of the outer peripheral iron core, or positioned to be coupled to the inner surface, and coils wound around the iron cores. A gap through which magnetic coupling is possible is formed between one iron core of the at least three iron cores and another iron core adjacent to the one iron core. The reactor includes an end plate attached to one end face of the core body, and the end plate includes a protruding portion that partially protrudes in a direction away from an outer circumferential surface of the core body.

A core main body includes an outer peripheral iron core, and at least three iron cores. Between the two iron cores adjacent to each other, a gap being magnetically couplable is formed. The outer peripheral iron core includes a first outer peripheral iron core block and a second outer peripheral iron core block that are formed by stacking a plurality of magnetic plates, and an intermediate plate disposed therebetween. The intermediate plate includes an outer peripheral iron core corresponding portion corresponding to the outer peripheral iron core, a plurality of protruding sections protruding from an outer peripheral surface of the outer peripheral iron core, and engaging sections provided on the plurality of protruding sections.

A configuration for the rapid replacement of a faulty multiphase transformer includes a plurality of single-phase transformers each of which has a housing filled with an insulating fluid and in which a core having a higher-voltage and a lower-voltage winding is disposed. At least one bushing socket is connected by a winding connection lead extending within the housing to the higher-voltage or lower-voltage winding. At least one high-voltage feed-through or bushing can be inserted into the bushing socket and a cooling module, which can be detachably connected to the housing and is filled with insulating fluid, cools the insulating fluid.

A container arrangement for power transformers that are constructed from individual components. The components are releaseably connected to one another in such a way that simple mounting/demounting and separate transportation is made possible. At least some of the components are arranged in containers, wherein each container contains a predetermined type of components in such a way that the components necessary for intended construction variants of the power transformers at the use location are contained in a corresponding selection of containers. This renders possible the correct and efficient mounting of power transformers.

A modular system applied to transformers, particularly power transformers, which comprises a structure having modules coupled between each other by fixation means, in such a manner that, the set thus formed, is positioned in the perimeter of the tank of the transformer and to which it is possible to connect several equipment and components, so that the referred components and equipment are positioned in the interior of the tank of the transformer, thus permitting the access to the referred components and equipment, when carrying out maintenance, supervision or control work, as well as to permit the optimization in the manufacture thereof, assembly, transport and installation.

A transformer includes a transformer body, a tank, a conservator, a plurality of support fittings, and at least one mounting seat. Transformer body includes an iron core and a winding. Tank includes an upper tank, a middle tank, and a lower tank that are bonded together to form an internal space accommodating transformer body. Conservator is arranged at a position above tank. The plurality of support fittings are arranged side by side at intervals to support conservator. At least one mounting seat is bonded to both a peripheral wall of upper tank and a peripheral wall of middle tank, and fixed to tank, and the plurality of support fittings are attached.

A device support assembly for an electrical device, in particular a transformer or a power transformer, includes: a plurality of retaining units arranged on the device itself; and a support arrangement which has a plurality of load stabilizers. The electrical device is set down on the load stabilizers by the retaining units in an end position and/or rests and is arranged between the load stabilizers, at least in portions, after being set down.
