Abstract

The invention discloses an electromagnet with a current separating channel. The electromagnet comprises a movable iron core, a stationary iron core, a restoring spring, an electromagnetic coil, a housing, a left terminal, a right terminal and a coil bracket, wherein a pair of discharge electrodes are connected in series with two ends of the electromagnetic coil; the discharge electrodes comprise a left discharge electrode and a right discharge electrode; the left terminal is connected with the left discharge electrode, and the right terminal is connected with the right discharge electrode; the stationary iron core is arranged outside the movable iron core; the electromagnetic coil surrounds the stationary iron core; the movable iron core, the stationary iron core, the restoring spring and the electromagnetic coil are erected in a cavity of the housing through the coil bracket; when a power current arrives, the movable iron core quickly moves under the action of an electromagnetic force; when a lightning impulse current arrives, induced voltages generated at two ends of the electromagnetic coil instantaneously break down the two discharge electrodes. The electromagnet disclosed by the invention not only can act under a small current to realize the purpose of drive, but also can divide a relatively strong lightning impulse current, so that the service life of the electromagnet is prolonged.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201110115066.1, the application date is May 5, 2011, and the invention name is "An Electromagnet with a Current Sorting Channel". technical field [0002] The invention relates to an electromagnet, in particular to an electromagnet with a current sorting channel. Background technique [0003] Currently used in various miniature circuit breakers, the moving iron core of the electromagnet generates action according to the power frequency current passing through the coil. This power frequency current is also called the action current to achieve the purpose of driving. Ideally, for an electromagnet that outputs rated thrust, the smaller the driving power required, the better, that is, the smaller the operating current through the electromagnet coil, the better the effect. To reduce the operating current, the number of coil turns must be increased; the increase in th...
