Abstract
The invention discloses an electromagnet with a current separation channel. The electromagnet comprises a movable iron core, a static iron core, a return spring and an electromagnetic coil. The electromagnet with the current separation channel is characterized in that a pair of discharging electrodes is connected with two ends of the electromagnetic coil in parallel. The electromagnet with the current separation channel, disclosed by the invention, has the beneficial effect of being capable of resisting scores of kiloamperes of lightning impulse current due to the addition of the current separation channel, thus the electromagnet can act under a small current to achieve a driving purpose and also can shunt a stronger current such that the service life of the electromagnet is prolonged.
Description
Technical field
The present invention relates to a kind of electromagnet, particularly a kind of electromagnet with electric current sort channel.
Background technology
Be applied to the electromagnet in the various miniature circuit breakers at present, its moving iron core is to produce action according to the power current by coil, and this power current claims operating current again, reaches driving purposes.Desirable state is, the electromagnet of output normal thrust, and needed driving power is the smaller the better, and just the more little effect of operating current by electromagnet coil is good more.Reduce operating current, must increase wire circle; The number of turns increases the line footpath and will reduce; Coil diameter is little, and big electric current has come coil to burn out easily.
Summary of the invention
Purpose of the present invention is that a kind of electromagnet with electric current sort channel will be provided, and only needs very little power current, and moving iron core can produce normal thrust, reaches the purpose of driving; And when lightning impulse current arrived, sparking electrode can be finished heavy current shunting task.
The present invention is achieved in that described a kind of electromagnet with electric current sort channel, and it comprises the electromagnet of being made up of moving iron core, static iron core, recovery spring, solenoid, it is characterized in that: in the two ends of solenoid pair of discharge electrodes in parallel.
Pair of discharge electrodes of the present invention be hemisphere protrude partly in opposite directions or other shape projection in opposite directions; Described sparking electrode is open type or is the sealed gas discharge tube.
The invention has the beneficial effects as follows that owing to increased the electric current split channel, electromagnet can tackle the lightning impulse current of tens kilo-amperes, make electromagnet under little electric current, to move, reach driving purposes, can shunt than heavy current again, prolonged the useful life of electromagnet.

Embodiment
A kind of electromagnet of the present invention with electric current sort channel, shown in Fig. 1,2,3,4, it comprises the electromagnet of being made up of moving iron core 3, static iron core 4, recovery spring 5, solenoid 6, and in parallel a pair of hemisphere is protruded part sparking electrode in opposite directions at the two ends of solenoid 6.Also indicate housing 1, left terminals 2, coil brace 7, right terminals 8, right sparking electrode 9, left sparking electrode 10 among Fig. 3.
Among Fig. 4, D is the moving iron core of electromagnet, can be along arrow direction.L is a solenoid, and A, B are the coil channel two ends, and S is the gap discharge device.Power current is by A, through solenoid L arrival B end, and electromagnet moves rapid movement unshakable in one's determination, reaches the purpose of driving.When lightning impulse current arrives,, have only the small part electric current, make D rapid movement unshakable in one's determination by coil L because electric current to the time rate of change height, produces induced potential at the L two ends.The induced potential that the L two ends produce makes the moment puncture of S splaying, and impulse current arrives the B end through discharging gap, finishes electric current shunting task.
Among Fig. 3, when power current arrives,, move iron core 3 rapid movement under the effect of electromagnetic force, reach the purpose of driving by left terminals 2, through the right terminals 8 of solenoid 6 arrival.When lightning impulse current arrives,, have only the small part electric current to make 3 rapid movements unshakable in one's determination by solenoid 6 because electric current to the time rate of change height, produces induced potential at solenoid 6 two ends.The induced potential that solenoid 6 two ends produce makes two sparking electrode moment punctures, and the impulse current of tens kilo-amperes passes through smoothly, finishes electric current shunting task.
The origination action electric current of the moving iron core of the present invention is not more than 15A, the impulse current by two sparking electrodes is not less than 20kA.
