Description

The invention relates to software devices and, in particular, to devices for controlling electrical circuits of time devices. five

Known software devices have a large number of switching sockets, which limits the number of programmable circuits, as well as the cycle and accuracy of programming and complicates design 1.

The aim of the invention is to simplify the design of the device, to increase the programming accuracy and ease of switching.

This goal is achieved by the fact that the device switch is equipped with two temporary groups of single-wire insulated sockets, duplicating the stator contacts of the time of distribution devices corresponding to these groups of sockets, and the time of distribution devices is provided with single-wire cords with plugs.

FIG. Figure 1 shows the design of a device switch 25 for 24 hours with programming accuracy in 1 minute; in fig. 2 - device linear kit; in fig. 3 — Switch Designs with JQ Programming Accuracy

0.1 s programming cycle 24 hours; in fig. 4 - Special linear programming kit with greater accuracy and a long cycle.

The design of the soft switch consists of two groups of single-wire sockets, duplicating the stator contacts of the switchgear time (hours, minutes) and arranged in a specific order convenient for the production of switching programs. The nests of the group of nominal units of time may differ by the diameter of the nests. For the purpose of switching programs through unambiguous sockets, transitional parallel sockets 1 and 2 are provided.

The line set consists of 2 relays, each of which has two single-wire cords, terminated with plugs of different diameters, corresponding to all the sockets of the switch. Relay 3 double winding. Its main winding is designed to work from the time of the switchgear and is under voltage for the shortest programming period when the brushes of the switchgear will be electrically connected to the winding. The second winding of the relay 3 is interlocking and works as long as this interlock exists, i.e. until the relay 4 is activated. The plug of the cords may have sockets for parallel connection of other linear sets, if necessary.

When switching a complex program along the same circuit, when the sockets of minutes are repeated in different hours when the electrical circuit is turned on or off, each electrical circuit is switched on and off is switched by a separate linear set, and the electrical circuit control contacts of all linear sets are connected in parallel and fed to a programmable circuit. .

Thus, the number of linear sets of devices depends on the number of programmable circuits and the complexity of their programs.

If it is necessary to increase the accuracy of programming (for example, when it is required to create a device with a programming accuracy of 0.1 s and with a programming cycle of 24 hours), two switches capable of operating independently (1st cycle of 24 hours, accuracy of 1 min and 2 th cycle 1 min., accuracy 0.1 s) through a special linear set.

A special set in the program switching circuit and in the program switching circuit has one normally open contact: 5 and 6. The windings of relays 7 and 8 are also terminated with single-wire cords, with which the program is switched.

With the cords of relays 3 and 4, the additional program is switched in seconds and tenths of a second by the second switch. Thus, the combined operation of relays 7 and 3, 4 and 8 will allow you to get any program in the time range of 0.1 s - 24 h.
