Abstract
The mewly developed contactor features that there is no maintaining current during suction and that the contacts are in vacuum and thus have no burning loss of spark discharge, Unlike available contactors, Which is noisy, high in power consumption and high in temperature rise, the present invention has advantages of simple structure, saving in power, high reliability and operational flexbility.
Description
The present invention relates to a kind of novel energy-saving contactor, belong to low tension switch.
At present, the use amount of China's threephase motor is very big.Generally all control with A.C. contactor.But " A.C. contactor is usually with alternating current operation, has that sound is big, power consumption is many, shortcomings such as iron core and coil temperature rise height." purpose of (selecting from 1345 pages of 1981 3 China Machine Press " simple and clear eelctrical engineering handbook ") this invention is a kind of new technical scheme that provides for the many shortcomings that overcome all kinds of contactors of existing usefulness.
The characteristics of novel energy-saving contactor of the present invention are: do not have the electric current of keeping in its adhesive work or when disconnecting, and each contact is in the vacuum, avoids sparkover.
Purpose of the present invention can be realized by following structure, and shown in Figure of description one: the inner chamber at one section nonmagnetic substance (as glass, aluminium, porcelain etc.) garden column jecket 1 is equipped with three segment garden plungers, is respectively A, B, C.The thin straight metal rod O break-through in its center.The two ends of thin straight metal rod O respectively with the center fixation of garden plunger A, C, garden plunger A, C are closely fixing with the inner chamber two ends of garden column jecket 1 respectively again, and between two plug A, the C certain intervals are arranged, plunger B place, garden is in the middle of it, and can horizontally slip on thin straight metal rod O.
Shown in Figure of description two: the outer wall 2 of garden plunger A is soft magnetic material pipe (as iron pipes), puts down with insulating material 3 (as moulding firmly etc.) filling in the pipe.Evenly inlay three groups of (or many groups) pressure switches on the medial surface of insulating material 3, K
1, K
2, K
3, and a little more than filling face, connect the lead of respectively organizing switch and closely draw from the opposite side of garden plunger A by the insulation charges.The structure of garden plunger A and C is identical.
Shown in Figure of description three: the outer wall of garden plunger B is a rare earth permanent magnet pipe 5, and its two sides is respectively N, the S utmost point, and is flat with 4 fillings such as insulating material in the pipe.The external diameter of garden plunger B is slightly less than the internal diameter of garden column jecket 1, and can horizontally slip by thin straight metal rod O.
Shown in Figure of description one: the outer wall at garden column jecket 1 is with two groups of coil L
1, L
2, corresponding with the position of garden plunger A, C respectively, the direction of winding of two coils is opposite, and after the series connection, the lead-out wire two ends are a, b.
Principle of the present invention and effect are:
As coil L
1And L
2Two ends a, b when connecting with DC power supply positive and negative electrode moment respectively by starting switch, the outer wall iron pipe of garden plunger A, C is magnetized, its inboard is the S utmost point, and the outer wall of garden plunger B is the permanent magnetism pipe, and the left side is the N utmost point, the right side is the S utmost point.Old home plunger B is subjected to the attraction of garden plunger A and is subjected to the repulsion of garden plunger C and slides K left
1, K

2Coiling two ends a, b when changing the sense of current by shutdown switch moment, the inboard of garden plunger A, C is the N utmost point, garden plunger B slides to the right, and with garden plunger C adhesive.K

6Because of the pressurized closure.
The two ends of garden column jecket 1 are salable, only draw the switch plain conductor, and garden plunger A, B, C are in the vacuum, and thin straight metal rod O can do zero line and use.
The present invention has following advantage:
1, during the action of this contactor, electric current is kept in no adhesive, so not power consumption of coil, do not generate heat.
2, all contacts all can be in the vacuum, so the contact is difficult for because of the sparkover scaling loss.
3, simple in structure, dependable performance, flexible movements.
The present invention has two kinds of embodiments:
1, shown in Figure of description one: nonmagnetic substance pipe 1 two ends integral sealing only picks out several groups of switch leads.Make garden plunger B and all switch contacts be in the vacuum the alternative used senior vacuum contactor of this contactor.
2, shown in explanation accompanying drawing one: nonmagnetic substance pipe 1 integral body is not done encapsulation process, makes garden plunger B and all switch contacts be under the normal pressure the alternative used general contactor of this contactor.
Claims (3)
1, novel energy-saving contactor, it is made up of garden column jecket, garden plunger, coil etc.It is characterized in that three segment garden plungers being housed, be respectively A, B, C at the inner chamber of one section nonmagnetic substance garden column jecket 1.The center of three segment garden plungers is by thin straight metal rod O break-through.Garden plunger A, C fix with the inner chamber two ends of garden column jecket 1 respectively, and between two plug A, the C certain intervals are arranged.Garden plunger B is between garden plunger A, the C, and can horizontally slip on thin straight metal rod O.Position in the outer wall of garden column jecket 1 and garden plunger A, C correspondence is with two groups of coil L
1And L
2
2, novel energy-saving contactor according to claim 1, the feature of garden plunger A, C is: its outer wall is one section garden post iron pipe, and is flat by the insulating material filling in the pipe, three groups of (or many groups) pressure switch K are inlayed in its inboard.
3, according to claim 1,2 described novel energy-saving contactors, the feature of garden plunger B is: its outer wall is one section rare earth permanent magnet pipe, and the two sides is respectively N, the S utmost point.Its external diameter is slightly less than the internal diameter of garden column jecket 1, and is flat with fillings such as insulating material in the pipe, and can horizontally slip on thin straight metal rod O.
