Description

This invention relates to a low power apparatus. According to the main author, No. 708431, a polarized electromagnetic relay is known that contains at least two independent cores with a common magnetic conductor and control windings and several contact groups, each of which is installed with the ability to interact with only one core to build reliable automation schemes, in which the relay is controlled by a signal of a certain magnitude. The relay is made in one-stable or in a two-stable version and can contain 3 of each version as a separate one. and collectively opposing devices, such as springs, non-magnetic gaps between the core and the magnetic cores in both one and both extreme positions, for example, in the form of non-magnetic gaskets 1. X There is a wide variety of automation schemes that require connection or shutdown of some circuits of the circuit by a certain program, depending on the value of the oetojero control signal. However, this relay, which has increased reliability and compactness, does not provide for software transfer of Korea. The purpose of the invention is to enhance the functionality of the relay by providing software to trigger the relay contact groups. The goal is achieved by the fact that the relay is equipped with an opposing mechanism, made in the form of elements with individual opposing characteristics that act with a bark, and the opposing characteristic of the hygiene element corresponds to a predetermined program for triggering contact groups. In this case, the opposing mechanism can be executed, for example, in the form of a comb-shaped plate with a spring-loaded plate, each comb of which has a certain width, due to the required opposing characteristic. A variant of polarized relays is possible, when each of the Koreas is completed and / or installed with the ability to provide conduction to the magnetic flux corresponding to a given weaver response program.

and interacting with them contact groups, for example, by installing an appropriate gap between each core and the poles of the magnetic circuit.

Figure 1 shows an embodiment of a relay with a counter mechanism in the form of a comb-shaped spring plate; Fig. 2bb are embodiments of a comb-shaped spring plate.

The relay contains a U-shaped magnetic core 1, a control coil 2, permanent magnets 3, which are connected to each other by identical end poles, and abutting the magnetic core, core 4, contacts 5, base 6, and a comb-shaped base on two bases , the crests of which abut against the pushers 8 fixed on the bark, the hem of which adjusts the force created by the ridge on the measles.

The relay, made with the opposing mechanism in the form of springs of the comb-shaped plate, works as follows.

In the absence of a control signal, all the core due to the resultant force generated by the opposing spring, the contacts and fluxes of the permanent magnets are in their original stable position. As the control signal and, accordingly, the magnetic flux generated by this signal and opposing the flow of permanent magnets increase, the resulting force is weakened, keeping each measles in its original position. When the control signal reaches the value at which the resulting force acting on the measles associated with the narrow ridge itself becomes equal to zero and then changes its direction, this measles is thrown while the rest of the core remains in its original position. Further increase the control signal leads to alternate throwing of the koreas in a sequence determined by the width of the ridge associated with the bark. After the last core is thrown over, the permanent magnets flow is completely redistributed. The control signal can be increased continuously or fed discretely, and the discrete value of the control signal should correspond to the response parameters of the corresponding core. In the case of one-stable execution of the relay, with a decrease in the control signal, the forces holding the core in the second position decrease, and at certain values the release of the Koreas occurs in the reverse order of response. In the case of a doublestable relay execution, the controller beggars;

second position in the absence of a control signal due to the greater force of permanent magnets than counter-force. The resetting of the two-stable relay korea is accomplished by changing the polarity of the control signal, which, like in a single-stable relay, can be changed continuously or discretely. The relay works in a similar way with other countermeasure mechanisms

and also in the presence of different non-magnetic gaps between the poles of the magnetic circuit and the cortex. The large non-magnetic gap between the magnetic core and the core in its unhooked position increases the response parameters of the relay, and in the tightened position increases the release parameters of the one-stable relay and vice versa.

The use of the opposing mechanism with different opposing characteristics and the implementation of non-magnetic gaps of different sizes is possible both individually and in

aggregate, and in the latter case, a wider relay operation program is provided.
