Problems solved by technology

[0004] Moreover, the existing arc extinguishing methods are not only complex in structure, but also require the polarity of the wiring
In the actual application process, if the wiring is reversed, it will not only not extinguish the arc but also aggravate the accumulation of the arc

Embodiment 1

[0031] Embodiment one: if Figure 1-7 As shown, a single-magnet arc extinguishing relay includes an arc extinguishing chamber housing 1, a static contact 2, a moving contact 3 and a lifting device for driving the moving contact 3 up and down. The arc extinguishing chamber housing 1 is formed There is an accommodation groove 11, and an arc-extinguishing magnet 4 is arranged in the accommodation groove 11, and the arc-extinguishing magnet 4 is located between the static contact 2 and the moving contact 3; the magnetic field direction and the current direction in the arc-extinguishing magnet 4 Vertical or nearly vertical angle.

[0032] This technical solution specifically discloses a high-compatibility relay manufacturing scheme. At the same time, by grasping the relationship between the direction of the magnetic pole in the magnet and the direction of the current, the core point of this technical solution lies in the design of the direction of the magnetic field. 3 and the cur...

Abstract

The invention discloses a single-magnet arc-extinguishing relay, and belongs to the technical field of relays. The single-magnet arc-extinguishing relay comprises an arc-extinguishing chamber shell, astatic contact, a movable contact, and a lifting device for driving the movable contact to move up and down, wherein a containing groove is formed in the arc-extinguishing chamber shell; an arc-extinguishing magnet is arranged in the containing groove and is located between the static contact and the movable contact; the magnetic field direction in the arc-extinguishing magnet is perpendicular toor approximately perpendicular to the direction of the electric current; and at least one magnet is also arranged in the containing groove and is at least distributed at one side of the arc-extinguishing magnet. The single-magnet arc-extinguishing relay can solve the arc phenomenon often occurring in relay products by requiring only one of the most common magnets. Regardless of the polarity direction of the magnet installation, the production efficiency can be greatly improved. As only one magnet is needed to achieve the arc extinguishing effect, the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of relays, in particular to a single-magnet arc-extinguishing relay. Background technique [0002] At present, the relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity excitation quantity meets the specified requirements. It has an interactive relationship between the control system, also known as the input loop, and the controlled system, also known as the output loop. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] In electrical appliances with contacts, the process of making and breaking current by the contacts is often ...
