Description

  The present invention relates to a moving transformer configured such that a transformer is mounted on a truck or the like and can be used when an accident occurs in an electric power system or a substation.

  When an accident occurs in an electric power system or a substation, a moving transformer used for securing a construction power source or an emergency power source in case of a disaster has been proposed. This transformer for movement is a transformer that can be moved while being loaded on a truck or trailer. The transformer that steps down the electricity received at the extra high voltage (110 kV to 22 kV) of the distribution transformer to the distribution voltage (22 kV to 6 kV). It can be used as a common spare for several substations in order to supply electricity in case of accidents or inspection / repair of substation equipment. As shown in the side view of FIG. 7, a structure in which a mobile transformer 51 is integrated with a vehicle T has been proposed.

For example, a moving transformer that houses a transformer, a switch, a cable, and a protective device, and that changes the pole transformer without interruption is disclosed in Japanese Patent Application Laid-Open No. 10-224918. A box that is mounted on a vehicle loading platform and houses a transformer, a switch, a cable, and a protection device, and rubber feet that are fixed to several locations including the four corners of the lower surface of the box, Proposed is provided with a plurality of suspension fittings provided on the upper surface of the box, and a plurality of wires in which both ends are connected to the suspension fittings and the loading platform, and the box is fixed to the loading platform. .

  However, a self-propelled mobile transformer such as the “Transformer Transformer Device” in Patent Document 1 has been stored in a state where it is always loaded on a dedicated vehicle such as a truck in order to ensure quick response in the event of an accident. . The operation of such a self-propelled mobile transformer was very small and was wasted because the vehicle part of the truck was not used for the original transportation work. The vehicle part of the truck has a problem that a regular inspection cost is incurred regardless of whether it is in operation or not.

  In addition, the "Transformer Transformer Device" of Patent Document 1 is a device in which a box containing a transformer, a switch, a cable, and a protective device is mounted on a loading platform of a vehicle. The cargo bed was connected with a wire. Since loading and unloading of boxes is not possible with a single vehicle, a crane or a unic is required, and the mounting work tends to be large.

  The present invention has been developed to solve such problems. That is, an object of the present invention is to make it possible to easily mount a moving transformer on a transporting vehicle such as a truck by configuring the moving transformer so as to be detachable from the transporting vehicle. An object of the present invention is to provide a mobile transformer that can be easily installed at a required place.

The transfer transformer according to the present invention is a transfer transformer that can be loaded and moved on a transport vehicle (T), wherein a winding is wound around an iron core, and a main body tank that accommodates the winding; A transformer body (1) comprising a bushing (3, 4) for pulling out a terminal of the winding to the outside of the body tank; a radiator (5) for cooling the inside of the body tank; and the transformer body (1) A container base (7) of a substantially rectangular plate material on which the machine base is placed, a lifting device (13) which is provided on the front side and the rear side of the container base (7), and which can be raised and lowered, and each lifting device (13) a wheel (14) attached to the lower end, and further comprising a.
