Abstract
The utility model relates to an electrical switch, in particular to a novel bidirectional direct-acting tap changer. The utility model is realized in the way that the tap changer is composed of a stationary part and a moving part, wherein the stationary part is composed of a fixing frame, a fixed contact with a buffer spring, permanent magnet, an electromagnet stationary frame, a guide rod and a fixed contact spacer, and the fixed contact, the permanent magnet, the electromagnet stationary frame, the guide rod and the fixed contact space are installed on the fixing frame; the moving part is composed of a transmission body and a guide plate which are electromagnetic armature fixedly installed on the transmission body, and a moving contact with a buffer spring and a magnetizer, wherein the moving contact and the magnetizer are fixedly installed on the guide plate. The utility model has novel design and reliable motion; because the fixed contact and the moving contact are both provided with the buffer spring, the fixed contact and the moving contact tightly contact and do not generate electric arc; because of the action of the permanent magnet and the magnetizer, after the utility model acts, an electromagnet coil is not electrified, and thus the utility model saves electricity.
Description
Technical field
The utility model relates to a kind of electric switch, particularly a kind of two-way direct drive type electro air cock, promptly a kind of novel tap changer.
Background technology
Tap changer is to be used for the device of make-and-break contact, and tap changer is applied in the regulating circuit of various electronic equipments.
The kind of tap changer is a lot.A.C. contactor is exactly a kind of tap changer that cut-offs and control that is widely used as electric power.It utilizes main contact to open and close circuit, carries out control command with auxiliary contact.Main contact generally has only normal opened contact, and auxiliary contact often has two pairs of contacts with Chang Kai and normally closed function, and small-sized contactor also often cooperates main circuit to use as auxiliary relay.The contact of A.C. contactor is made by silver tungsten, has good electrical conductivity and high temperature resistant ablative.The weakness of A.C. contactor tap changer is in order to guarantee the connection of main contact, and its line bag will be switched on always, relatively expends the energy.Again by a kind of big electric current tap tap changer of forming by moving contact, fixed contact and pivot structure form, be to be that three dull and stereotyped centers of insulation are on the expansion circumference in the center of circle, form with five equilibrium is provided with fixed contact, the moving contact that pressure regulation conducting strip big or small and that thickness equates is formed this switch equably by the progression of regulating, rotating shaft switches on and off moving contact, fixed contact, this tap changer contact is good, but rotates harder.The applicant in first to file a kind ofly be used for limiting " balanced loss " and abnormal condition or the fault of bringing owing to three-phase power is load unbalanced, improve the device of the safe condition and the quality of power supply, i.e. voltage-regulation type three-phase load unbalanced limiter.Voltage-regulation type three-phase load unbalanced limiter is in order to guarantee user's quality of voltage and to improve the quality of products and a kind of well behaved tap changer of power savings advantage needs.
The utility model content
The purpose of this utility model is to provide a kind of novel tap changer, and promptly version is the novel tap changer of two-way Direct Action Type.
The utility model is to realize like this, a kind of novel tap changer, constitute by stationary part and motion parts, wherein, stationary part by fixed frame and be fixedly mounted on fixed contact on the fixed frame, permanent magnet, electromagnet rest frame, guide post with buffer spring, and the fixed contact spacer constitute, motion parts is by transmission body and be fixedly mounted on electromagnet armature, the guide plate on the transmission body and the moving contact with buffer spring, the magnetic conductor that are fixedly mounted on the guide plate constitute;
Further, described fixed frame or be the block form fixed frame, or be the boxlike fixed frame;
Further, described permanent magnet is corresponding with magnetic conductor, respectively is more than two;
Further, described guide post is two.
The beneficial effects of the utility model
1, the utility model modern design operates reliably;
2, the utility model is because fixed contact, moving contact all have buffer spring, so that fixed contact contacts with moving contact is firm, and no electric arc generation;
3, owing to the effect of permanent magnet and magnetic conductor, after the utility model moves, but electromagnetism iron wire bag no power, thereby the utility model economizes on electricity, power saving, is low carbon products.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Will illustrate a bit at first to be that Fig. 1 is a structural representation of the present utility model, understand structure in order to make everybody, understand operating principle, the applicant represents stationary part of the present utility model and motion parts two parts respectively with oblique line and oblique ruling.
In Fig. 1, novel tap changer is made of stationary part and motion parts, wherein, stationary part by fixed frame 1 and be fixedly mounted on the fixed contact with buffer spring 2 on the fixed frame 1, permanent magnet 3, electromagnet rest frame 4, guide post 5, and fixed contact spacer 6 constitute, motion parts is by transmission body 8 and be fixedly mounted on electromagnet armature 7, the guide plate 11 on the transmission body 8 and the moving contact with buffer spring 9, the magnetic conductor 10 that are fixedly mounted on the guide plate 11 constitute; Fixed frame 1 is made by metal or plastics, and its shape or be the block form fixed frame, or boxlike fixed frame are the block form fixed frame here, and the boxlike fixed frame can be used in the arc extinguishing occasion; Permanent magnet is corresponding with magnetic conductor, respectively is more than two, respectively is four here; Guide post is two, and it is through on the guide plate 11 in the corresponding aperture, guarantees that motion parts moves up and down reliably; Electromagnetism iron wire bag is arranged in the electromagnet rest frame 4, and electromagnet armature can move up and down in electromagnet rest frame 4; Fixed contact 2, moving contact 9 are corresponding, respectively are more than two, respectively are six here, divide two groups up and down, three pairs every group.
During work, give the energising of electromagnet one line bag, electromagnet armature 7 moves upward in electromagnet rest frame 4, make three pairs of firm contacts of contact on the utility model top, simultaneously, the permanent magnet 3 on top attracts (but not contacting) mutually with magnetic conductor 10, and after the outage of electromagnetism iron wire bag, permanent magnet 3 attracts to make three pairs of contacts on the utility model top firmly to contact with magnetic conductor 10 mutually; Give electromagnet another line bag energising once more, electromagnet armature 7 moves downward in electromagnet rest frame 4, make three pairs of firm contacts of contact of the utility model bottom, simultaneously, the permanent magnet 3 of bottom attracts (but not contacting) mutually with magnetic conductor 10, equally, after the outage of electromagnetism iron wire bag, three pairs of contacts of the utility model bottom can also firmly contact.
This good low carbon products of the utility model can effectively be used in the various electronic equipments, also can effectively be used in the voltage-regulation type three-phase load unbalanced limiter, or in other low-voltage electrical apparatus.
