Description

Contactless contactor
Technical field
The utility model relates to industrial electric power field of switches, relates in particular to Contactless contactor.
Background technology
In the traditional industry production process, the electric equipment products that electric equipment is controlled all adopt A.C. contactor, so A.C. contactor is very big at the electric utility consumption, are the main elements of automation control.Operation principle is mechanical contact, electromagnetism adhesive.This A.C. contactor in use, the easy product of the closing of contact and disjunction fire arc causes other electric interference, when using in the imflammable gas environment, is very unsafe.The contact under rugged environment and the number of times that uses increase, the contact will cause loose contact, thereby cause the impact of production.Along with the development of modern industry, most of PLC and the DCS control mode of adopting of electric equipment, traditional A.C. contactor is difficult to competent its job requirement, and under the occasion of frequent movement, common A.C. contactor will be scrapped.
Therefore, we have introduced external advanced person's Contactless contactor product, adopt intelligent object control closed, have satisfied operational environment and the rugged environment of high frequency break-make, keep electric current and voltage stable.Yet, because external Electric Appliance Cabinet is different from domestic body structure, directly quotes imported product and be difficult at home market popularization and application.Reason is that mounting means and radiator structure and domestic electric control cabinet are difficult to mate the problem of bringing and are difficult to solve.External contactless employing be bolt fixed mode, we designed contactless be that clamping-rail and bolt can be installed, for the Replacement of some import and problem easy for installation, all solve at our Contactless contactor.The Contactless contactor heat radiation of import arranges unreasonable, and its heat radiation volume is too little, is unavailable under high temperature and rugged environment, and the safety of operation is difficult to guarantee; And the design of our Contactless contactor is to consider to work under rugged environment and the high temperature, it is easy for installation that secondly we go back the deisgn product auxiliary contact, direct and the A.C. contactor Alternate of Contactless contactor, because domestic these problems can not get solving always, the closure techniques that finally causes getting an electric shock is promoted very slow at home, it is supporting that relevant automatic field control system lacks corresponding element, the progress of China's modernization industry that seriously lags behind.
The utility model content
The purpose of utility model: good for a kind of heat radiation is provided, Contactless contactor easy for installation, that installation form is various.
In order to reach as above purpose, the utility model is taked following technical scheme: comprise the contactor body, fixedly jump ring and bolt brace are arranged on the described contactor body, on the bolt brace bolt connecting hole is arranged.
The further technical scheme of the utility model is, also comprises the fin that is positioned on the contactor body.
The further technical scheme of the utility model is, also comprises auxiliary contact, and described auxiliary contact are installed on the binding post with bolt.
The further technical scheme of the utility model is that described fin is divided into two groups, and two groups symmetrical.
Adopt as above the utility model of technical scheme, have following beneficial effect: can realize directly exchanging with common contactor, heat radiation is good, and is easy for installation, installation form is various.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure vertical view;
Fig. 3 is the structural representation that contains link; Wherein: 1. bolt brace; 2. fin; 3. auxiliary contact; 4. bolt connecting hole; 5. fixing jump ring.
Embodiment
Comprise the contactor body, fixedly jump ring 5 and bolt brace 1 are arranged on the described contactor body, bolt connecting hole 4 is arranged on the bolt brace 1.
The further technical scheme of the utility model is, also comprises the fin 2 that is positioned on the contactor body.
The further technical scheme of the utility model is, also comprises auxiliary contact 3, and described auxiliary contact 3 usefulness bolts are installed on the binding post.
The further technical scheme of the utility model is that described fin 2 is divided into two groups, and two groups symmetrical.
Contactless contactor has been drawn the iron core type installation and has been changed easily advantage, also draws the advantage of solid-state relay simultaneously, and has done corresponding improvement.The application of at present automation control is more and more extensive, what failure rate was high is exactly contactor and auxiliary relay, if select direct current Contactless contactor (YJX15-D voltage 12-24vdc) not need auxiliary relay, directly export Contactless contactor (drive current of direct current Contactless contactor is very little tens milliamperes) to by plc, following some benefit arranged like this:
1 adopts the import bidirectional triode thyristor, and power leaves enough surpluses, and the thorough embedding of high-quality epoxy resin is not subjected to such environmental effects, integral fin, and good heat dissipation, useful life is stable and long, and overload capacity is strong, and is not fragile.
Taken into full account accurate location on 2 circuit design, speed can reach 80 beats/mins of break-makes and accurate positioning, also quick break-make is processed the impact of motor simultaneously.
3 are applicable to adverse circumstances, frequent starting and pinpoint place, and it is wide to adapt to voltage range, and 98-280v exchanges (contains 110,220v) direct current 3.2v-32v (containing 5v, 24v)
The installation of 4 irony callipers can increase radiating effect and can play the grounding safety effect again, easy for installation, reliably not fragile, can large tracts of land use and do not increase the control cubicle volume, suit large area to popularize, can be widely used in the automation equipment occasions such as pottery, machinery, packing, plastics, cement, colliery, chemical industry, thermostatic device for heating, numerical controlled machinery, remote control system, medicine equipment, instrument and meter, computer external interface equipment, signal lamp, traffic lights, illumination stage lighting control device.Be specially adapted to that dirt is large, burn into is moist, require the adverse circumstances such as explosion-proof, and the occasion of frequent switch using, is that A.C. contactor upgrades substitute products.
5 have saved auxiliary relay, both reduced cost, this fault point that has not also had auxiliary relay, wiring and space in the cabinet have been simplified simultaneously, also just stopped loosening because of the end of a thread or the auxiliary relay base aging or auxiliary relay damages, or auxiliary relay poor contact of contacts and the fault (this fault is bad searching also) that causes has improved the reliability of equipment greatly.
6 control loops all are safe voltages, operate and be not prone to easily security incident;
7 because the minimizings of drive current, have greatly increased the useful life of PLC output point, simultaneously also can saves energy.Can use the output module of transistor output, further improve the speed of control, and needn't worry the wrong line.
8 could make the control cubicle miniaturization, have saved simultaneously the use of non-ferrous metal (iron core, copper, silver), are energy-conserving product! If spread uses, annual electric energy and non-ferrous metal quantity of saving is considerable.
The utility model can fast and easy dispel the heat, and does not affect the useful life of product.
In a word, have structural strength height, dustproof, damp proof, anticorrosion, the life-span is long, switching speed is fast, noiselessness, volume are little, no-spark, explosion-proof, the advantages such as antivibration is shock-resistant, anti-vibration resistance is strong, high-cooling property, automatic heat radiation.
Be summarized as follows:
Contactless contactor is described, the one side of binding post is arranged for positive, one side contrary to the positive is the back side, other face is the side, the Contactless contactor body back side is provided with fixedly jump ring and bolt, can directly Contactless contactor be clipped on the card rail or with bolt by fixedly jump ring and bolt and be installed in the electric control cabinet convenient fixing.
