Abstract
The invention discloses a double-coil combined direct current traction electromagnet and belongs to the technical field of electricity and electromagnets according to International Patent Classification (IPC). The double-coil combined direct current traction electromagnet is aimed to solve the technical problem of great difference between the initial suction and the final suction of an existing electromagnet. The double-coil combined direct current traction electromagnet is mainly composed of a gag bit, a clamp spring, a pagoda spring, a framework, a coil 1, a coil 2 and a time relay. When the double-coil combined direct current traction electromagnet is connected with a power supply, the coil 1 is in parallel connection with the coil 2 through the time relay, the resistance is small, the current is high, the power is high, and therefore, the initial suction is increased; when the time arrives at the set time of the time relay, the coil 1 is in serial connection with the coil 2, the resistance is increased, the current is decreased, the power is decreased, and therefore, the final suction is decreased. By means of the double-coil combined direct current traction electromagnet, the technical problem of great difference between the initial suction and the final suction is solved. The double-coil combined direct current traction electromagnet is applicable to the technical field of electricity and electromagnets and is featured with broad application, easiness in manufacturing, low cost, convenience in use and easiness in popularization.
Description
Technical field
The present invention relates to a kind of twin coil combination DC traction electromagnet, belong to electricity by International Classification of Patents (IPC), electromagnet group. technical field.
background technology
Current DC traction electromagnet is all single group magnetizing coil, and the number of turns and the electric current of the coil of single group magnetizing coil are constant, are permanent magnetomotive force, square being inversely proportional to of suction F and gap delta.
So just suction and whole suction are to differ greatly.
Summary of the invention
[0006][0003] the object of the present invention is to provide a kind of twin coil combination DC traction electromagnet, overcome the deficiency that first suction and whole suction differ greatly.
The technical solution adopted for the present invention to solve the technical problems is: this invention twin coil combination DC traction electromagnet is mainly by: Hyun iron; Jump ring; Pagoda spring; Framework; Coil 1; Coil 2; The time relay forms.Its time relay is selected by market. and the twin coil combination DC traction electromagnet series of the present invention technical characterictic different from immediate prior art is: while connecting with the mains, 5 of coil 1 is connected with 7 of coil 2 by the normally closed interlock 12,13 of the time relay; 6 of coil 1 is connected with 8 of coil 2 by the normally closed interlock 14,15 of the time relay, and composition coil 1 is in parallel with coil 2, and time in parallel, resistance is little, and electric current is large, and power is large, and therefore just suction increases; Arrive the setting-up time of the time relay, normally closed interlock 14,15 with normally closed interlock 12,13 trippings, normally open contact 18,19 closures, normally open contact 16,17 closures, 6 of coil 1 passes through the normally open contact 16 of the time relay, 17 are connected with 7 of coil 2, and composition coil 1 is connected with coil 2, and when series connection, resistance increases, electric current reduces, power reduction, therefore whole suction reduces, and has so just realized first suction that twin coil of the present invention combination DC traction electromagnet solves and whole suction and be the object of technical problem of differing greatly.
Twin coil combination DC traction electromagnet of the present invention
seriesbeneficial effect be: the technical scheme that the technical problem that the first suction of solution differs greatly with whole suction is taked has two advantages and improvement compared with the technology of existing unicoil DC traction electromagnet:
The first, due to twin coil combination DC traction electromagnet of the present invention
seriestechnical scheme in designed twin coil and the time relay is combined into series-parallel transition circuit, while starting to connect with the mains, it is parallel circuits and can be as required that change-over time is as far as possible short, what parallel-current can be designed is very large, so just suction is also just very large, like this, for needs, just suction is large, if the requirement of longevity of service designs and needs increasing power and volume with unicoil DC traction electromagnet, so twin coil of the present invention combination DC traction electromagnet has advantages of energy-conservation and reduces costs.
The second, due to twin coil combination DC traction electromagnet of the present invention
seriestechnical scheme in designed the combination of twin coil and the time relay, at coil 1, the wire diameter of coil 2 has according to the need and possibility very large choice with the change-over time of number of turns ratio and the time relay within the scope of the rated power of electromagnet, so twin coil of the present invention combination DC traction electromagnet has advantages of the scope of application extensively and flexible design.
accompanying drawing explanation:
Accompanying drawing provides twin coil combination DC traction electromagnet structural representation of the present invention
Fig. 1: be twin coil combination DC traction electromagnet structural representation of the present invention
Fig. 2: be twin coil combination DC traction electromagnet electrical schematic diagram of the present invention
Fig. 3. be square curve chart being inversely proportional to of unicoil DC traction electromagnet suction F and gap delta, illustrate that first suction and whole suction are to differ very greatly different.
The label declaration of parts in schematic diagram:
1 Hyun iron 2 jump ring 3 pagoda spring 4 framework 5 coil 16 coil 17 coil 28 coils 2
9 air gaps 10 connect wire 11 time relays
embodiment:
Below in conjunction with accompanying drawing, the optimal way of the technical scheme that the technical problem that the first suction that twin coil combination DC traction electromagnet of the present invention is solved and whole suction differ greatly is taked is described further:
Its static structure: ask Shenfu figure: as shown in the figure, twin coil combination DC traction electromagnet of the present invention is mainly by 1 Hyun iron 2 jump ring 3 pagoda spring 4 framework 5 coil 16 coil 17 coils 2
8 coil 29 air gaps 10 connect wire 11 time relays and form. and 2 jump ring 3 pagoda springs 10 connect wire 11 time relays to be selected by market, selects the time relay to notice that requirement selects the time relay identical with work of electromagnet voltage.
1 Hyun iron is material by A3 unit steel, and after machined into manufacture, electrogalvanizing forms. 4 frameworks are material by A3 steel plate, and after punch press processing and manufacturing, electrogalvanizing forms. and 5 coil 16 coil 17 coils 2
8 coils 2 are material by enamelled wire, and through coil winding machine, coiling forms.
The coil that coiling forms is arranged in framework by structural representation Fig. 1, the jump-ring slot of jump ring Ka Hyun iron, put pagoda spring, then insert in the Hyun iron hole of framework. coil 1,4 tie lines of coil 2 link by the requirement of electrical schematic diagram Fig. 2, and connecting with the mains and just having realized like this first suction that twin coil combination DC traction electromagnet of the present invention solves and whole suction is the object of technical problem of differing greatly.
Realizing preferred plan of the present invention is to utilize existing unicoil DC traction electromagnet unicoil to change system into such practical value and the economic worth that just can realize better twin coil combination DC traction electromagnet of the present invention of twin coil.
