Energy-saving electromagnet device with quick-start double-coil structure

Abstract

The invention discloses an active energy-saving double-coil electromagnet device which comprises a shell, a power interface, a first coil, a second coil, a microswitch assembly and a movable armature. A movable sliding groove is formed in the shell. The power interface is provided with a live wire terminal and a zero wire terminal, and the power interface is installed on the shell; the first coil is wound on the outer side of the movable sliding groove; the second coil is wound on the outer side of the movable sliding groove; the live wire terminal, the first coil, the microswitch assembly and the zero wire terminal are connected in sequence to form a first current loop; the live wire terminal, the first coil, the second coil, the microswitch assembly and the zero wire terminal are sequentially connected to form a second current loop; the microswitch assembly is provided with an elastic driving rod; the movable armature is installed in the movable sliding groove, moves in the movable sliding groove and drives the elastic driving rod. The electromagnet device has the capability of automatically adjusting current, and energy waste is reduced. Large current is generated at the starting moment, rapid starting can be achieved, and the response time is shortened.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic devices, and in particular relates to an energy-saving electromagnet device with a quick-start double-coil structure that can be used in the field of aerospace engines. Background technique [0002] Electromagnet products require a large starting current at the moment of starting. After starting, the armature is pulled in, and the required maintenance current is much smaller than the starting current. Most of the existing electromagnet products do not have the ability to automatically adjust the current, so that when the electromagnet products are working, their maintenance current is the same as the starting current, resulting in a waste of energy. However, there are currently a few dual-coil electromagnet products designed with different resistance values. In order to achieve the ability to adjust the current, it needs to be controlled with a power controller. The operation and maintena...

Most of the existing electromagnet products do not have the ability to automatically adjust the current, so that when the electromagnet product is working, its maintenance current is the same as the starting current, resulting in a waste of energy

However, there are a few dual-coil electromagnet products designed with different resistance values. In order to achieve the ability to adjust the current, it needs to be controlled with a power controller. The operation and maintenance costs and use effects are not ideal.
