Description
Technical field
The utility model belongs to the control apparatus technical field, and this vacuum contactor is a kind of Industry Control electrical equipment, and it is on the basis of former CJ40-630 air A.C. contactor, to improve to form.
Background technology
Original C J40-630 normal air contactor.Installation dimension like CJ40-630 air A.C. contactor is bigger, and volume is big, Heavy Weight, external form are not attractive in appearance, neither energy-conservation yet, and also not environmental protection has noise simultaneously, and pedestal is the aluminium alloy pedestal.
The utility model content
The purpose of the utility model provides a kind of vacuum contactor.
A kind of vacuum contactor; Form by pedestal, electromagnetic system, control circuit rectifying device, haulage gear and five basic parts of contact system; The material of pedestal changes the compacting of DMC high-intensity resin into by original aluminium alloy and forms; Electromagnetic system has starting winding electromagnetic coil and the solenoids that keep winding respectively by two, two static iron core, yokes of being processed by electrical pure iron and be fastened on the armature on the haulage gear and the O type circle that is used to cushion is formed the dynamical system of vacuum contactor; Haulage gear constitutes the L type by the rotating shaft and the armature card that are embedded in the DMC high-intensity resin; The base plate that contact system is formed by DMC high-intensity resin compacting, three lead-in line rows, three outlet rows and three pairs are sealed in the indoor contact of vacuum extinction to be formed, and an end of moving contact is equipped with draw bar, moving contact compression spring and spring base and limited part; Its volume and overall dimension taper to Min..
This vacuum contactor is made up of pedestal, electromagnetic system, control circuit rectifying device box, haulage gear and five basic parts of contact system, shown in accompanying drawing 2.
1, pedestal
The pedestal of this vacuum contactor is that according to other design of part of product, through optimal design, material changes the compacting of DMC high strength resin into by original aluminium alloy and forms under the constant prerequisite of the installation dimension that guarantees original CJ40-630 normal air contactor.Accompanying drawing 3 is the used aluminium matter pedestal of former normal air contactor, and accompanying drawing 3 (a) is a DMC resin pedestal for this vacuum contactor.
2, electromagnetic system
The electromagnetic system of this vacuum contactor by two respectively by starting winding and the solenoid that keeps winding, two static iron core, yokes of processing by electrical pure iron be fastened on the armature on the haulage gear and the O type circle that is used to cushion is formed.It is the dynamical system of vacuum contactor.
3, control circuit
Control circuit is by silicon stack, piezo-resistance, electric capacity, fuse, binding post and be used to switch the starting winding and keep the auxiliary switch of winding to form.Electronic component is connected by printed circuit board (PCB), is connected with auxiliary switch, coil windings through binding post then, and is as shown in Figure 5.
4, haulage gear
Haulage gear is formed the L type by the rotating shaft and the armature that are embedded in the DMC high strength resin, sees shown in the accompanying drawing 6.
5, contact system
Contact system is to be sealed in the indoor contact of vacuum extinction the base plate that is formed by DMC high strength resin compacting, three lead-in line rows, three outlet rows and three pairs to form.At the first end of the indoor movable contact of vacuum extinction draw bar, moving contact compression spring and spring base are housed, see shown in the accompanying drawing 7.
With comparison with similar product
Compare with common CJ20, CJ40 series air contactor, have more environmental protection.
Static iron core and yoke that electromagnetic system is processed by two doublewound solenoids, two electrical pure irons are formed.Double winding is a starting winding, and one keeps winding, makes maintenance power consumption very low (seeing table 1 for details) after the contactor starting.
The static iron core that electrical pure iron is processed has not had common contactor to laminate the magnetic hysteresis eddy current loss of the iron core that silicon steel sheet processes and the noise that alternating voltage causes when passing to the direct voltage of rectification.Low energy consumption and quiet operational environment have been accomplished fully.
Because dynamic and static contact is sealed in the vacuum tube, can not make air ionization produce electric arc.Probe of contactor is to adopt high connecting-disconnecting function, high-breakdown-voltage, high anti-galvano-cautery property, the low high performance materials such as current value, low gas content amount that dam of anti-melting welding ability to process; Owing to there has not been poisonous silver alloy such as Agcdo, the environment-friendly products of " zero discharge ", " zero noise " that made realization that this contactor is real.
Compare with common CJ20-630, CJ40-630 contactor, more material-saving
As shown in table 1 below
So, comprehensive other parts of relatively going up table and whole product, at least can 280 yuan/platform of economical with materials cost about.Calculate with annual 3000 output, can save more than 800,000 yuan.
This vacuum contactor is improved on the basis of former CJ20-630 and CJ40-630, is keeping under the constant prerequisite of former installation dimension the volume and the overall dimension of having dwindled product greatly.See the following form 2:
The raising of important technological parameters (seeing table 2 for details)
Compact with the comparative structure of similar vacuum contactor, good looking appearance.
The vacuum contactor that CKJ5 series vacuum contactor is used more generally at China's coal, chemical industry, metallurgy industry.The specification of its rated current below 400A, design are rational, compact.No matter all come with some shortcomings in various degree but the CKJ5-630 vacuum contactor is outward appearance or reliability aspect.
The CKJ5-630 vacuum contactor is a horizontal type structure, its auxiliary contact system on the right because its haulage gear unreasonable; Make that the profile of product is very big, very not attractive in appearance, original horizontal type structure is changed in the design of this vacuum contactor; With reference to vertical profile and the mounting structure of CJ20-630; Make the volume of product dwindle greatly, weight saving, more elegant in appearance.
The design of haulage gear is than the more reasonable structure of former CKJ5
The haulage gear of this novel evacuated contactor (shown in accompanying drawing 6) adopts to be annotated round steel rotating shaft precompressed in DMC resin material, has guaranteed the consistency of 3 connecting lever sizes by mould, has reduced the processing link of numerous parts.And the bearing of supporting revolving shaft has also accomplished do not have special bearing pedestal on the pedestal, has also reduced the quantity of part, on pedestal, can also fully be guaranteed the consistency of size by mould.Make that so the same period, time≤3ms was not able to reliable assurance for the three-phase of product.
The optimal design of control circuit
At present, the control circuit principle of vacuum contactor generally adopts single change-over circuit.Yet the user often finds owing to the short circuit of circuit version is burnt coil or overvoltage and the electrical equipment misoperation in the process of using.For this reason, through after the repetition test, the circuit that generally uses is now improved.Shown in accompanying drawing 5.It is existing that partly client, user use the back reflection to produce a desired effect.
The comparison of technical parameter
The part technical parameter of CKJ5-630 vacuum contactor is selected from " People's Republic of China's coal industry standard " MT/T498-1995, and all the other contents are from the technical conditions regulation of the same industry.The long 230-270mm of volume profile installation dimension pedestal of this vacuum contactor, wide 200-220mm, high 215-245mm, wide between lead-in line row and the outlet row is 235-270mm.
