Abstract

The invention relates to a control switch, especially to a magnetic fluid switch with copper nano particles and a distributed combination method. The switch is characterized in that a magnetic fluid state is changed by controlling a magnetic field direction so as to realize closing, disconnection or selection of a circuit. According to the magnetic fluid, copper nano particles are mixed with temperature-sensing insulating magnetic fluid and a retention agent is also added to keep a uniform mixing state. On the basis of the principle, a distributed structure of a magnetic fluid switch is designed; and rapid combination can be realized according to different practical demands. In addition, the invention also includes a specific structure of a magnetic fluid switch and a distributed combination method thereof. Compared with the prior art, the magnetic fluid has good performances of heat radiation, sealing, and easy aging prevention. The magnetic fluid switch enables the original switch operation mode to be changed and a novel switch material and a novel combination method are invented. On the basis of the distributed structure, the modularized design combination can be realized rapidly; and multi-channel selection and capacity expansion of the switch terminal are realized.

Description

technical field [0001] The invention relates to a control switch, in particular to a magnetic fluid switch with copper nanoparticles and a distributed combination method. Background technique [0002] As a common electronic component that controls the closing and opening of circuits, the switch can be seen everywhere in our daily life. At present, with the increasing demand for global power transmission and distribution equipment and its components, it also drives the rapid development of my country's power transmission and distribution equipment. However, at present, our country has overcapacity in low-end products, but there is no breakthrough innovation in high-end product technology. [0003] The main directions of switch research and development include: high frequency, reliability, low energy consumption, anti-interference and modularization. Modularization is the general trend of switch development, but currently there is no effective modular switch design method. ...
