Description

The invention relates to electrical engineering, in particular to an electromagnetic relay.

The aim of the invention is to reduce the size and weight, reducing power consumption.

The drawing shows an electromagnetic relay, a general view.

The relay contains measles in the form of a saNiKHy loop, consisting of the same elements 1, winding 2 controlled and located on the core, base 3, fixed contacts 4-7. The elements 1 are made of an elastic ferromagnetic material and, with their middle part, are fixed on the base 3. They simultaneously perform the function of moving contacts. The fixed contacts A-7 are fixed on the base and together with the elements 1 form switching contacts. The ends of two adjacent elements 1 are placed with a gap between: against each other. The number of elements 1 may be two or more. A permanent magnet 8 is mounted in the middle part of the closed loop of the core.

In the absence of a signal in the winding 2 control stationary contacts 4 and 7 are closed, and contacts 5 and 6 are open. When voltage is applied to the winding 2 of the control under the action of magnetic forces, the ends of the elements 1 are bent and the fixed contacts 5 and 6 are bent and closed. When the voltage is removed under the action of its own elastic forces, the ends of the elements 1 return to their original position.

The NOM force of the magnetic field of the permanent magnet 8 is insufficient for attracting the ends of the elements 1, contacts 4 and 7 are closed. When a control pulse is applied to the winding 2, a magnetic field is generated in the elements 1 that is directed according to the magnetic field of the permanent magnet 8 , the ends of the elements 1 are attracted and close the contacts 5 and 6. When applying a reverse polarity pulse, the relay returns to its original state.
