Description

The invention relates to electronic switching devices and in particular to a switching device, which is used to send a current pulse through a predetermined branch of an electrical network pass through.

It has already been proposed to use switching circuits containing magnetic cores of the type which have a substantially rectangular hysteresis characteristic to form such that they have a Can pass current through a predetermined branch of a network. According to this proposal pairs of cores are provided, and the one core of each pair is set to be the predetermined Select branch. The cores are provided with a number of windings, each of which one attached to one end of each branch of the network. Each branch contains a rectifier, and when an interrogation pulse and a control pulse are supplied to the cores, each is set Core reset and the control pulse passed through the predetermined branch.

A circuit of this type is used, for example one of six binary digits to decipher the existing code into its sixty-four different outputs, then have the Cores of the core pair corresponding to the highest digit of the code, each thirty-two output windings in addition to the setting windings and the query and control windings. The winding up However, all of these windings on a magnetic core are extremely difficult Problem.

It can be seen that a circuit of this type, which is only connected to one end of the branches of a Network decrypted, useless for the selection of a branch from a large number of branches is because, for example, to select a branch from a thousand and twenty-four branches, which work with a code consisting of thirty-two binary digits, each core of the 32nd core pair would require five hundred and twelve output turns.

The main purpose of the invention is to provide an electronic switching device that is at both ends decrypts the branches of a network and thereby enables a current pulse through any a large number of branches, e.g. B. by any branch out of one thousand twenty-four or two thousand forty-eight branches to pass through.

According to the invention comprises an electronic switching device for passing a current pulse through a predetermined branch of an electrical network two sets of magnetic Cores, each core of which has an adjustment winding, electronic switching device

is the branch that is connected to the control windings that interconnect all the cores that have been discontinued. Therefore, if z. B. the current pulse is to be passed through the branch 6, the cores 10, 11 and 26 set.

In order to simplify the construction of the pulse generator 34, the line 17 can be removed from earth and its previously grounded end connected to the control line 20 after it has been supplied by the pulse generator 34 is switched off. Then only an impulse needs to be generated and this impulse works as a query pulse and at the same time as a control pulse.

It should be noted that in the illustrated in Fig. 1 simplified switching device, the cores 25 and 26 further cores can be assigned to form a set of cores, and that for each an additional pair of cores a further control winding is provided which runs through the cores 25 and 26, and two more groups of branches are included in the network. For example Sixty-four branches form a branch by deciphering one of six binary digits To be able to select a number, each set consists of three pairs of nuclei, and there are 11 on each of the nuclei, 12, 25 and 26 have eight expensive windings as opposed to thirty-two control windings the output cores of the device according to the previous proposal.

Figure 2 illustrates a switching device according to the invention for energizing a number of branches 35 to 46 of an electrical network, one of which is excited at a time in a sequence. Each branch again contains a rectifier 31 and a load resistor 32. The branches are in six groups of two branches each.

Each set of cores is designed as a ring counter that has an even number of stages. Of the one set consists of six cores 47 to 52, and the other set consists of four cores 53 to 56. The maximum number of branches from which a branch can be selected is the smallest common Multiples of the number of counter steps, i.e. from six and four, i. h, twelve. Every core has one Setting winding 57, an interrogation winding 58 and a control winding 59. The interrogation windings 58 the odd cores 53, 55, 51, 49 and 47 are connected in series through an odd interrogation line 60, one end with a pulse generator 34 and the other end with the S expensive windings 59 of the Cores 47, 49 and 51 connected. Similarly, the query coils 58 of the even cores 54, 56, 52, 50 and 48 connected in series by a straight-line interrogation line 61, one end of which is connected to the pulse generator 34 and the other end thereof connected to the adjustment windings 57 of the cores 47, 49 and 51 is.

The control winding 59 of the core 47 is connected in series with the setting winding 57 of the core 48, and this adjustment winding 57 is connected to one end of the branches 35 and 36. The other end of branch 35 is connected to control winding 59 of core 53, which is also connected to branches 40 and 43 and is connected to earth via the setting winding 57 of the core 54. Similarly, are the adjustment windings 57 of the cores 49 and 51 with the control windings 59 of the cores 48 and 50, respectively the control windings 59 of the cores 49 and 51 are connected to the adjustment windings 57 of the cores 50 and 52, respectively. The adjustment winding 57 of the core 47 is connected to the control winding 59 of the core 52. In appropriate Way are the windings of the set of cores 53 to 56 with each other and with the branches 35 connected to 46 of the network.

The cores 47 and 53 each have an additional identification winding 62 and are initially set by applying an identification pulse to the windings 62. After that, the interrogation lines 60 and 61, starting with line 60,

ίο alternately a pulse from the pulse generator 34 is supplied, and the first pulse on line 60 resets cores 47 and 53, causing the cores 48 and 54 can be set by the current flowing in their setting windings 57 and a blocking voltage is applied to all rectifiers 31 with the exception of the one in branch 35, so that the pulse running on line 60 is passed through branch 35. Then from the pulse generator 34 a pulse on the line 61

ao applied so that the cores 48 and 54 are reset, the cores 49 and 55 are set and all rectifiers 31 with the exception of the one in branch 37 are blocked.

The next pulse on line 60 is passed through branch 39 and the Cores 50 and 56 are discontinued. When the next pulse is applied to line 61, the branch will 41 selected, the core 51 set and the core 53 set because the control winding 59 of the core 56 is connected in series with the adjustment winding 57 of the core 53. The control winding is in the same way 59 of the core 52 connected in series with the setting winding 57 of the core 47. The result is that the ring counter consisting of the cores 47 to 52 counts over two cycles, which consists of the Cores 53 to 56 existing ring counter counts over three cycles and the applied pulses through the Branches in the order: 35, 37, 39, 41, 43, 45, 36, 38, 40, 42, 44, 46, are passed through.

If it is desired to stop the ring counters after a predetermined number of the branches have been energized, then an additional control winding is provided on a corresponding core of each counter, these additional control windings being connected together between line 60 and ground. For example, if the counters are to be stopped after branch 42 has been selected, additional control windings on cores 51 and 55 are directly connected to one another by bridging the setting windings 57 of cores 52 and 56.

It can be seen that by increasing the number of cores in each ring counter, a greater number of network branches can be sequentially energized. For example, if one counter has eighteen cores and the other counter has fourteen cores, then one hundred and twenty-six branches can be energized in succession, the branches being arranged in eighteen groups of seven branches each.

Optionally, each set of cores can have more than one ring counter of the above with reference to Fig. 2 have the type described. For example, one hundred and twenty branches of an electrical network to energize successively, the one core set may have a ten-core ring counter, while the other core set may have a six-core ring counter and an eight-core ring counter. Of the Six-core ring counter has four control windings on each core, and the eight-core ring counter has three

Control windings on each core. These two counters are linked together so that twenty-four Paths are created in connection with ten outputs of the decentral commutator successively excite one hundred and twenty branches of a network, divided into ten groups of twelve each Branches are arranged.
