Abstract
The utility model discloses a field suppression switch closes a floodgate and reforms transform return circuit relates to field suppression switch technical field. Including former field suppression switch combined floodgate return circuit, former field suppression switch combined floodgate return circuit includes air switch and the pilot lamp and the circuit no. 1 and circuit no. 2 parallelly connected with the pilot lamp at circuit both ends, and circuit both ends are equipped with a set of parallelly connected normally open contact respectively to be equipped with resistance no. 1, diode and coil and resistance no. 2 between the normally open contact that allies oneself with, after resistance no. 1 is established ties with the diode again with the coil is parallelly connected, and the coil still is arranged in circuit no. 2, and two both ends in the circuit are equipped with the normally open contact of a set of series connection respectively, closes a floodgate two normally open contact in the contactor with field suppression switch and changes the combined floodgate return circuit of putting in series into by parallelly connected, and when drawing the arc, the arc overvoltage of drawing that single contact was undertaken reduces. So both the effectual combined floodgate contactor contact of having improved has been because of having drawn the arc to glue dead phenomenon, has guaranteed again in case take place certain contact and glue and die, because the combined floodgate return circuits that concern of two contact series connection also can reliably be broken off to the coil has been protected.
Description
Technical field
The utility model is related to degaussing switch technical field, and in particular to a kind of degaussing switch closes a floodgate and transforms loop.
Background technology
Degaussing switch, is exactly for the quick switch for reducing the electric current in energized circuit.When generator accident using jump
The rapid demagnetization of degaussing switch, when maintenance degaussing switch is disconnected, and forms obvious cut-off point.
At present mostly degaussing switch closing contactor normally opened contact is in parallel accesses closing circuit, but degaussing switch closes a floodgate and connects
Tentaculum normally opened contact is in parallel to access closing circuit, and the arcing that contact produces when disconnecting easily causes contacts of contactor and glues extremely, and will go out
Magnetic switch coil short, burns degaussing switch coil.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of by the normally opened contact of degaussing switch closing contactor two
It is changed to connect by parallel connection and accesses the degaussing switch combined floodgate transformation loop of closing circuit, improves the reliability in loop.
To solve above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of degaussing switch closes a floodgate and transforms loop, including former degaussing switch closing circuit, and the former degaussing switch closes a floodgate back
Road includes the air switch and indicator lamp and the circuit one in parallel with indicator lamp and circuit two at circuit two ends, the two ends of the circuit one
One group of normally opened contact in parallel is respectively equipped with, between the normally opened contact in parallel resistance one, diode and coil and electricity are provided with
After resistance two, the resistance one and Diode series again with the coils from parallel connection of coils, the coil is also located in circuit two, and its feature exists
In：The circuit two is respectively arranged at two ends with the normally opened contact of one group of series connection.
It is using the beneficial effect produced by above-mentioned technical proposal：
The normally opened contact of degaussing switch closing contactor two is changed to into series connection by parallel connection and accesses closing circuit, it is single in arcing
The arcing overvoltage that individual contact undertakes is reduced.Closing contactor contact had so both effectively been improved because dead phenomenon is glued in arcing,
In turn ensure that once there is certain contact and glue extremely, because the relation closing circuit of two contact series can also reliably disconnect, so as to
Protect coil.And so transformation principle is simple and clear, transformation is convenient, can also effectively improve the reliability in loop.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is circuit diagram of the present utility model；
Wherein, 1- linked switches, normally opened contact 2- in parallel, the normally opened contact of 3- series connection, 4- resistance one, 5- diodes,
6- coils, 7- indicator lamps, 8- resistance two.
Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be different from alternate manner described here to implement using other, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.
A kind of degaussing switch closes a floodgate and transforms loop, including former degaussing switch closing circuit, former degaussing switch closing circuit bag
Include the air switch 1 and indicator lamp 7 and the circuit one in parallel with indicator lamp 7 and circuit two at circuit two ends, the two ends of circuit one difference
One group of normally opened contact 2 in parallel is provided with, circuit two is respectively arranged at two ends with the normally opened contact 3 of one group of series connection, normally opened contact 2 in parallel
Between be provided with resistance 1, diode 5 and coil 6 and resistance 28, resistance 1 is in parallel with coil 6 again after connecting with diode 5,
Coil 6 is also located between the normally opened contact 3 of two groups of series connection in circuit two.
Two normally opened contacts 3 of degaussing switch closing contactor are changed to into series connection by parallel connection and access closing circuit, in arcing,
The arcing overvoltage that single contact undertakes is reduced so that the arcing voltage of the normally opened contact 3 of degaussing switch closing contactor two is by original
The 220V DC for coming are reduced to 110V DC, both significantly reduced the normally opened contact 3 of degaussing switch closing contactor two glue it is dead can
Energy property, even if in turn ensuring that normally opened contact 3 glues dead closing circuit and also can disconnect.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
