Abstract

Bistable relays are widely used in both general and special purpose engineering. Such relays are subdivided according to the construction principle into two groups: bistable electromagnetic polarized relays and bistable electromagnetic latching relays.

In the technical literature, there is practically no information on the design of the relay of the second group. This article highlights general issues of their design using the example of high-current relays of the DP-1 series for rated currents from 25 to 100 A, which have been used for a long time in autonomous power supply systems for military equipment. The descriptions of the distinctive features of the relay construction and the principle of its operation are given. The kinematic schemes of the main mechanism of the electromagnetic and contact systems are considered. The example of constructing the opposing characteristics of the relay is shown. The paper provides the replacement scheme for calculating of magnetic system on improved method of sections and assumptions, characteristic of the given relay construction.
