(54) CONVERTING DEVICE

one

The invention relates to the field of electrical engineering, namely to converting devices of alternating current into direct current, direct current into alternating current, alternating current of one frequency into alternating current of another frequency.

A device is known comprising two conductive buses, valves, fuses, and means connecting them, which together form the straightener arm. In the STONI device, the valves are located on one bus, and the fuses on the other 1. The disadvantage of this device is the heat load from heat losses in the valves and fuses on each of the conductive shells.

It is also known that a converting device of RoystBo contains at least one SMpy 1yr 5SHy tin tin-iH; chains of parallel connected, consisting of valves and fuses 2, are installed on the harness.

In this device, each pair of tires 20 has valves on one of them and fuses on the other. , The disadvantages of this device in L are different heat load from

heat losses in the valves and fuses on each of the tires, since the losses in the valves and fuses are not the same; incomplete use of the length of one of the tires, which leads to an increase in the dimensions of the device.

The aim of the invention is the uniform distribution of heat loss between the tires.

The goal is achieved by the fact that valves and fuses are installed on each tire, and on one of the tires there are direct conduction valves connected to fuses located on the other bus, on which reverse conduction valves are also located, connected to the fuses of the first tire .

Another object of the invention is to reduce the size.

This goal is achieved by the fact that the valves and fuses are arranged in a shahmatny order.

FIG. 1 shows a converter device, top view; in fig. 2 - the same, front view; in fig. 3 is an electrical connection diagram.

On two tires 1 and 2, fixed by insulators 3 on base 4, valves 5 of one conductivity are mounted on Tsin 1, connected by plate 6 with fuse 7 on bus 2, and valves 8 of other conductivity on bus 2, also connected by plate 6 s fuse 9 tires 1.

In the presence of valves of tablet construction, valves of the same conductivity can be used on one conductor bus, for example, the cathode side, and on the other anode one.

The device works in the following way.

A direct current, for example, enters the bus 2, passes through the fuses 7 and the valves 5, as well as the valves 8 and the fuses 9 and leaves the wire w, its element 1.

The device does not allow reverse current, since the valves in all parallel circuits are turned on to meet it.

The device allows you to evenly distribute the heat loss between the tires, which makes it possible to increase the load capacity of the valves and the power of the installation, as well as to increase the reliability of the valves because of their better cooling.

In addition, the arrangement of valves and fuses on tires in a staggered order allows better use along the length

And, therefore, to reduce the size of the device, as well as to ensure the convenience of one-way service.
