Abstract

The invention relates to automation and switching technology and can be used in automatic control systems, control, measurement and communication of various branches of technology as a pulsed switching element with bipolar control. The aim of the invention is to increase reliability. The device consists of a gezacon, on different halves of the bulb of which three control windings are placed, a ferromagnetic shunt located in the zone of overlap of the contact parts of the gezacon, and two semiconductor diodes. The device is controlled from one source of short-term bipolar pulses. In this case, the connection circuit of the control windings and semiconductor diodes is such that it allows pulses of one polarity (for example, positive) to turn on the device, and pulses of the other polarity to turn on the device. 2 Il.

Description

The invention relates to automation and switching technology and can be used in automatic control systems, monitoring, measuring and communication as a pulsed electromagnetic switching device with memory, controlled by short-term bipolar pulses.

The aim of the invention is to increase reliability.

FIG. 1 shows the scheme of ferride; in fig. 2 - the cyclogram of its functioning.

The ferride contains control windings 1--3 installed on the heater 4, ferromagnetic shunt 5 installed in the working gap of the heater, diodes 6 and 7. Winding 1 is installed on one side of the flask 4 relative to the ferromagnetic shunt 5, and windings 2 and 3 - on the second side of the flask of the gezacon 4. All three windings are connected in series, with the windings 1 and 3 wound opposite each other, and the winding 2 is in agreement with respect to winding 1

 and counter to winding 3. The common junction point of the windings 1 and 2 is connected to the cathode of diode 6, the anode of diode 6 is connected to the anode of diode 7, with the common junction point of the anodes of diodes 6 and 7 being the common junction point of the winding ends 2 and 3. The beginning of the winding 3 is connected to the cathode of the diode 7 and is connected to the second terminal, intended for connecting a generator of bipolar pulses.

The number of turns of the control windings 1 to 3, equal to W / i, W-a and No. h, respectively, is selected from the conditions for ensuring the operation and release of the hexazon (a group of hexazons, if there are several of them). In this case, the operation of the device is carried out under the influence of the MDS of two consonant windings

The operation of the device is carried out under the influence of short-term bipolar control pulses and proceeds as follows. Suppose that in the initial state the windings are de-energized, the contact parts of the gezacon are demagnetized, the load (Fig. 2) is turned off. The first control pulse of the current / 1 positive polarity is fed to terminal I from the generator of bipolar pulses and passes from the positive terminal B through windings 1 and 2 and diode 7 to the negative terminal. At the same time, windings 1 and 2 are consonant MDS, which according to magnetize the contact parts of the gezakon. a nh the total value is equal to md spabatyvani
