Abstract

The invention relates to the field of electrical engineering and can be used in the design of switching elements in automation. The purpose of the invention is to increase the electrical strength of the insulation and switching voltage. When a current pulse is applied to the winding 8 and 19 of the control, the membrane 6 is closed with the ferromagnetic core 14, and the electrical contact between the said contact pairs remains after the end of the signal supply. The opening of the contacts occurs when a pulse of opposite polarity is applied to the windings 18, 19. Supply current pulses only for one control winding, it is possible to switch only membrane 6 with core 14 or membrane 7 with core 15. 5 Il. 2 2ff (About fff about :) About with About About N :) f 3 Figure 1

The invention relates to electrical engineering and can be used in the design of switching automation elements.

The aim of the invention is to increase the dielectric strength of the insulation and the commutated 1 crt of the membrane reed switch.

The membrane reed switch (Fig. 1) contains a ferromagnetic ring 1, which has two internal seating slots 2 and 3. Membranes 6 and 7 are attached to ring 1 by means of centrifugal rings and 4 and 5 are attached to the tops of the ferromagnetic ring i ceramic insulators 8 and 9 form a clonu-ie insulating cylinder. Metal nipples 10 and 11 are attached to the ceramic insulators 8 and 9, in the center of which holes 12 and 13 are pierced, through which ferromagnetic cores 14 and 15 pass. Between the ferromagnetic core 14 and the membrane 6 and, there is a EYUZ-dunny gap 16, and between the ferromagnetic core 15 and the membrane 7 is an air gap 7. On the ferromagnetic cores 14 and 15 there are control windings 18 and 19 that ensure the commutation of the membrane 6 with the ferromagnetic core 14, and the membrane 7 with the core 15. Between the nails 10 and 11 are electrically connected heart bound nicks 14 and 15, the actively-connected capacitive voltage divider consisting of two Sequence. but coefficients equal to the size of the capacitors 20 and 21 of the same capacity, in which common point 22 is connected to the ferromagnetic ring 1 through the limiting resistance 23. Between the ferromagnetic cores 14 and 15 and the non-magnetic PI bits I) and 11 (Fig. 3) The range of insulating sections 24-29, for example, made of ceramics, is arranged between which there are three ferromagnetic rings 30-32 with a membrane 33-38, and two ring terminals 39 and 40 with central 41 and 42 and additional 43 and 44 holes. Fixed ferromagnetic cores 45 and 46 are fixed in the central apertures 41 and 42. An external voltage is connected between the washers 10 and II; a voltage strainer consisting of a single lacquer in magnitude of the capacitors 47-52, connected in series, with a common connection point of each | 1x two capacitors are connected to the corresponding ferromagnetic

ring through the restrictive resistance 53-57.

The device works as follows.

When a current pulse is applied to the windings 18 and 19 of the control, the membrane 6 closes with the ferromagnetic core 14, the membrane 7 with the ferromagnetic core 15, and the electrical contact between the said contact pairs remains after the signal is given. The opening of the contacts occurs when the pulses of opposite polarity are fed to the windings 18 and 19. Supply current pulses to only one of the control windings, 18 or 19, it is possible to switch only membrane 6 with ferromagnetic core 14 or membrane 7 with ferromagnetic core 15.

Improving the dielectric strength of the insulation is achieved by using the principle of sectioning an insulating cylinder. Additional ports 43 and 44 serve to pump out gas from the inner cylinder of the membrane reed switch, as well as to equalize the pressure in the gas-filled membrane reed switch.
