As made in the background art, prior art is substantially based on transmission of electricity for the status monitoring of transmission line of electricity at present
The conducting state of circuit judges, the drawbacks of this method has very big：1st, detection high-voltage power line conductive leads to the equipment of state
Cost and difficulty larger 2, in same circuit there are multiple controlling switches, the conducting for monitoring transmission line of electricity cannot essence
Equipment or position that true judgement is broken down, for the transmission line of electricity of remote mountain areas, this is undoubtedly the increase in failure
Investigate difficulty.
And use the electromagnetic switch with feedback device described in above-mentioned technical proposal just to can be good at solving this
Problem, certainly, in order to realize more succinct monitor mode, user can use radio transmitting device to transmit to the present invention's
Backfeed loop binding post collection signal, and the innovation of this point and non-invention, are just seldom described herein.
The ingenious part of the present invention is what is mutually linked between moving contact and conductive swing rod, with reference to being oppositely arranged on base
On four groups of binding posts（Left backfeed loop binding post 9, right backfeed loop binding post 12, first coil binding post 10,
Second winding wiring terminal 13）, automatically powering off and feedback function for this electromagnetic switch is realized jointly, is especially noted that
For the design of moving contact, as long as can realize that deviation post turns on the function of any circuit loop all the way, its structure
Design can have various ways, as shown in Fig. 2 set on the base 1 a left push rod for being provided with second spring 17 and

On the baffle plate 16 of base 1, swing rod both sides, which are provided with chute, chute, sets two push rods that can be moved left and right, and is pushed away using push rod
Left moving contact 11 and right moving contact 14 is moved to realize the control of the "on" position to each loop；Certainly, for moving contact
There can also be many schemes with the structure design of conductive swing rod 3, as those skilled in the art, realize that left moving contact 11, the right side are dynamic
The linkage of contact 14 and conductive swing rod 3 is easily achieved.
Another point is it should be strongly noted that the present invention also has an especially ingenious part, when remote control terminal is to the electricity
When magnetic switch carries out remote control, the electromagnetic switch can perform control instruction（Complete the conductive stationary contact of swing rod 3 and first
The switching of contact condition between the stationary contact 5 of point 4 or second）Disconnect the circuit loop of first coil or the second coil automatically afterwards.
Further illustrate below in conjunction with the accompanying drawings：
With the state shown in accompanying drawing 1（Conductive swing rod 3 is contacted with the second stationary contact 5, i.e. between the second stationary contact 5 and conductive swing rod 3
Line conduction）For original state, the attraction under the state due to right permanent magnet 8 to electromagnet core, conductive swing rod 3 will be right dynamic
Contact 14 promotes a segment distance to the right, and now right moving contact 14 disconnects the connection with the second winding wiring terminal 13, keep with
Right backfeed loop binding post 12 is connected（I.e. right backfeed loop is switched on）, and it is located at the left moving contact 11 on the left of electromagnetic switch then
The left moving contact 11 of free state-now is maintained to leave left backfeed loop binding post 9 and protect with first coil binding post 10
Hold connection.
If at this time remote control terminal is powered to first coil binding post 10（Send the control signal of switching circuit）,
Electromagnet 6 will be produced and the right identical magnetic pole of electromagnet 8, according to the attracting principle of homopolar-repulsion, heteropole, the conductive swing rod 3
Will be flapped toward in the first stationary contact 4, swing process, because right movable contact 14 returns to free state, right movable contact 14 disconnect with
The connection and holding and the connection of the second winding wiring terminal of right feedback control signal binding post 12.
After conductive swing rod 3, which is rocked to, to be contacted with the first stationary contact 4, the left push rod 9 is pushed to left side, described left dynamic tactile
First 11 keep the connection with left backfeed loop binding post 9（I.e. left backfeed loop is switched on）Disconnect and connect with first coil again simultaneously
The connection of line terminals.
If desired electromagnetic switch is switched back into original state again, remote control terminal only needs to be powered the second coil
.
In above process, due to the ingenious combination of the part such as conductive swing rod 3 and left moving contact 11, right moving contact 14, holding
When row control signal, left moving contact 11 and right moving contact 14, which are also acted as, automatically controls first coil loop and the second coil go back to
The effect of road break-make, this for avoid sometimes remote control terminal forget closing control signal cause electromagnet for a long time energization
It is highly effective, it is the design of a unusual hommization.
Certainly, if keeping powering to first coil and the second wire loop simultaneously（I.e. there are abnormal feelings in remote control terminal
Condition, such as operator forget to close certain and after control signal and carry out new control operation all the way）, we are analyzed it can be found that originally
The conductive swing rod 3 of invention will ceaselessly carry out right position swing, and remote control terminal will necessarily also find the feedback letter of its collection
Number exception（I.e. left backfeed loop binding post and right backfeed loop binding post alternately collect connection signal）, this is just realized
The function of false alarm, it is to avoid the maloperation of operator.
Further, second spring 15, described one end of second spring 15 are additionally provided between the conductive swing rod 3 and base 1
On conductive swing rod 3, the other end is arranged on immediately below the rotating shaft 2.
For the position of second spring, basic ideas of the invention be realize conductive swing rod 3 have in swing process to
The tendentiousness of left side or to the right side oscillation, so as to realize the stationary contact good contact of conductive swing rod 3 and any side.This area
Technical staff can show that the scheme optimized the most should be according to general knowledge：The other end of the second spring be connected to two it is quiet
On the midpoint of contact and the line of rotating shaft 2, and position is below rotating shaft 2.
It is preferred that, the conductive swing rod 3 is contacted between the first stationary contact 4 and the second stationary contact 5 for face.Obviously
Ground, face contact is conducive to avoiding between the conductive stationary contact of swing rod 3 and first and the second stationary contact electric arc thing caused by loose contact
Therefore.
Further, the electromagnet 6 is located on conductive swing rod 3 close to the conductive top of swing rod 3, the second spring 15 1
End be connected to conductive swing rod 3 close to rotating shaft 21 at 3, the other end is connected to the underface of rotating shaft 2 on base 1.
Electromagnet 6 is provided close to the position on the conductive top of swing rod 3, the work torque of electromagnet 6 can be increased, electricity is reduced
The operating current of the coil of magnet 6, on the other hand, is arranged so as to also help the installation of second spring 15, comes for the present invention
Say, second spring 15 plays the effect that the conductive swing rod 3 of increase contacts dynamics with the first stationary contact 4 or the second stationary contact 5, in reality
In, vibration, the interference of electromagnetic field may slightly deflect the position of conductive swing rod 3, at this time easily cause electricity
Arc accident, and the electromagnetic switch provided with second spring 15 can substantially increase whole electromagnetic switch completely not by above-mentioned interference
Reliability.
Finally also need to emphasize a bit, of the invention is simple in construction, control that its realization is fed back and electromagnet coil is powered
