Abstract

The invention provides a magnetic switch capable of adjusting the distance between the arc extinguishing grids, relates to the technical field of magnetic switches, and solves the problem of the magnetic switch in the prior art. If the distance between the arc extinguishing grids and the voltage and current do not match the arc extinguishing effect, the Significantly reduced, the use of magnetic switches has been limited and constrained by technical issues. The device includes a shell with an upper end opening and an arc extinguishing cover matched with the open end of the shell; the arc extinguishing cover is movably connected to the open end of the shell; a magnetic control switch device is arranged inside the shell, The arc extinguishing cover is provided with an arc extinguishing device; the arc extinguishing device includes several arc extinguishing grids arranged inside the arc extinguishing cover, and the distance between adjacent arc extinguishing grids is adjusted by a spacing adjustment device . The invention expands the application range of the magnetic switch, and can achieve good arc extinguishing effects under multiple voltages and currents.

Description

Technical field[0001]The invention relates to a magnetic switch, in particular to a magnetic switch with adjustable arc extinguishing grid spacing.Background technique[0002]Magnetic switch is a line switch device controlled by magnetic field signal, also called magnetic control switch.[0003]Most of the magnetic control switches in the prior art are the combination of electromagnet and switch. The working principle is that electromagnetic force is generated after the coil is energized, so that the movable iron core moves and pushes the switch contacts to be connected. The structure is complicated and the failure rate is high; Due to the unique distribution curve of the magnetic field, the closing speed decreases when the iron core moves away from the electromagnet, which will cause a large number of arcs to be generated, and the high temperature will easily burn the switch contacts and endanger the safety of workers, and the magnetic field force is not distributed. The uniformity cau...
