The invention relates to the electrical industry and can be used to install rechargeable batteries in non-mainline railway vehicles and electrically rolling stock, for example, subway cars.

The purpose of the invention is to improve the insulating properties and operational reliability.

In FIG. 1 shows the proposed device, a top view; figure 2 is a section aa in figure 2; in Fig.3 is a view along arrow A in Fig.2.

A device for placing a battery on an electrically rolling stock, for example, a subway car, comprises a battery holder body 1 and a tray 2.

The device is equipped with prefixes 3 made of a dielectric material, such as polypropylene, eliminating damage to the housing from electrolyte.

. Spacers 3 are made with protrusions 4 and spacers 5, which are placed between the battery elements 6 and are designed to isolate them from the walls of the gap between the battery elements 6 around their perimeter.

Spacers also have tides 7 to form the supporting surface of each battery element 6 of the battery and the hole 8 for draining the electrolyte.

The operation of the device is as follows. The battery cells 6, assembled into a two-row battery, are installed in the housing 1 on the supporting tides 7 and are fixed by spacers 3 due to their elasticity both from each other and from the walls of the housing 1.

During operation, the battery cells 6, due to the guaranteed technological air gap, do not damage the insulating spacers 3 and the holder body 1, which increases the service life of the latter by preventing contact of the electrolyte with dielectric spacers, which flows through the drain holes 8 outside the car box than protects it from decay and corrosion.

The battery is periodically inspected and subject to maintenance in accordance with the operating rules.

The use of the device of the invention will make it possible to abandon the commercially available rubber covers of the battery cells and, due to the simplicity of the design, it will significantly increase the service life of the battery, since the air gap between the battery cells is the best natural dielectric.

Formula of the invention

A device for placing an accumulator battery on an electrically rolling stock, comprising a holder in the form of a housing with a bottom and supporting elements, which includes that in order to improve the insulating properties and operational reliability, the housing is equipped with spacers from dielectric material with protrusions for placing them between the elements of the battery, covers for isolating the battery from the walls and the bottom of the housing and openings for the drain of electrolyte, and the supporting elements are made in the form of tides on spacers.
