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 purpose of the device is to increase the sensitivity and reduce the energy consumption for control. The device consists of a hezacon, on different halves of which two control windings are installed. The device is controlled from one source of short-term bipolar pulses. In this case, the connection circuit of the control windings and contact parts of the gezacon is such that it allows the pulses of one polarity to turn on the load, and the pulses of the other polarity to turn off the load. 3 il.

Wo For galvanic isolation of n.1gruak currents and control in a single-law device (Fig. 1), use a semiconductor diode 5, which prevents the control of go-impulses through the load R c In a two-law device (Fig. 2), the diode is not needed, so as the switching of the external load, R is carried out by an additional control switch, which ensures complete galvanic isolation of the control circuits and loads.

Structurally, the device is made in the form of a single complete module round g, 1 or oval section with a JI pin for printed wiring.

The operation of the device is as follows.

Suppose that in the initial initial state, the windings 1 and 2 are de-energized, the contact parts of the gezakin (gezakon) 3 are demagnetized, the load is closed for EC. When the first positive current pulse impulse n i arrives at the input from the generator, the current will pass about an input terminal B through; windings 1 and 2 aa vtg.ryu KJteMMy. CCTVs 1 and 2 will develop magnetizing species (and “s.) And F, respectively, F, i ,, .w ,, F, and their significant effect on the contact-parts of the gozg: horse will ensure their consistent magnetization and operation (zamEkanie) Gezakona.

At the same time, the contact parts will leak consonant magnetic fluxes f, and Ft, the total effect of which will ensure their closed state and switching on the load R (Fig. 3) before the arrival of the switching pulse of negative polarity.

to the tactics-parts of the m-law at the first terminal, while the current through the winding I will not leak, as it is shunted by the closed contact-contact parts. The second winding will develop a counter n. F 1, peremagnetit its contact-part, above which it is located. By contrast, the magnetic flux - F, which will ensure reliable disconnection of the contact parts of the gezacon and the switching off of the load К „(fig.З),

The next current impulse + i J is again running through both windings. In this case, the magnetized state of the first contact part is confirmed and the second one will magnetize, which will cause them to re-close and turn on the load (Fig. 3). Then the work cycles will be repeated.
