The utility model mainly solves the problem that when the voltage of the grid is temporarily decreased, the contactor tripping leads to the production line collapse. The utility model, comprising a control module body sealed in a plastic shell, is characterized in that the inside of the control module body is also provided with a motion time control circuit and the motion time control circuit is connected with a voltage detection device and a breaking controller. The utility model effectively prevents the production line collapse because of the temporary decrease of the grid voltage and the instantaneous problem in the process of time delay, thus stabilizing the production system and reducing the economic losses of enterprises.
Description
Technical field
The utility model relates to a kind of low-voltage electrical apparatus control device, specifically a kind of module for controlling permanent-magnetic AC contact of preventing the instantaneous interruption of voltage.
Background technology
The module for controlling permanent-magnetic AC contact that uses as shown in Figure 1 at present, adhesive when controlling voltage greater than 85%Ve, when controlling voltage, trip less than 50%Ve, do not trip when having control voltage, therefore (or instantaneous voltage interrupts when falling temporarily appears in line voltage, when being voltage decline 10%Ve duration 0.3～3S), can causing the contactor tripping operation and production line is disintegrated, thereby bring immeasurable loss to enterprise.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming; a kind of module for controlling permanent-magnetic AC contact of preventing the instantaneous interruption of voltage is provided; when falling temporarily appears in line voltage, can guarantee that the permanent magnet AC contactor does not trip, can obey the electric motor protecting action simultaneously again fully.
The technical solution of the utility model is: a kind of module for controlling permanent-magnetic AC contact of preventing the instantaneous interruption of voltage, comprise and be encapsulated in the control module body of moulding in the shell, it is characterized in that: also be provided with control circuit operate time in the control module body, this, control circuit connected voltage check device and disjunction control operate time.
In described a kind of module for controlling permanent-magnetic AC contact of preventing the instantaneous interruption of voltage, the contactor back panel wiring is, one of coil and soft iron core are fixed in the contactor base plate centre bore with screw, terminal A1, A2 on the terminal board, B1, B2 are connected with the control module body, according to the required control voltage of user, with respective coil lead-in wire and the welding of control module body; The contactor external cabling is, terminal A1, A2 connect by the attached normal opened contact of start button normal opened contact and contactor and seal in the control power supply after in parallel; Terminal B1, B2 are in parallel with stop button normal opened contact and protection normal opened contact three.
The beneficial effects of the utility model are: effectively prevent to be occurred falling temporarily and production line being disintegrated by line voltage, solved and in the time-delay process, needed moving problem of wink, make production system stable, prevent the economic loss that trips and cause by the big amplitude fluctuations of line voltage effectively to enterprise.

Embodiment
As shown in Figure 2.
A kind of module for controlling permanent-magnetic AC contact of preventing the instantaneous interruption of voltage, comprise and be encapsulated in the control module body of moulding in the shell, also be provided with control circuit operate time in the control module body, this, control circuit connected voltage check device and disjunction control operate time.Voltage check device judge magnitude of voltage and with this signal conveys give operate time control circuit, by operate time control circuit send instruction according to situation about setting to the disjunction control section.
As Fig. 3, Fig. 4, Fig. 5. earlier one of coil and soft iron core are fixed in the contactor base plate centre bore with screw, again terminal A1, A2 on the terminal board 2, B1, B2 and control module body 1 are assembled, according to the required control voltage of user, respective coil lead-in wire 3 is welded with control module body 1, promptly finish the contactor back panel wiring.
A1, A2 connect by start button normal opened contact attached with contactor (self-insurance) normal opened contact is in parallel and seal in the control power supply.As Fig. 3.
B1, B2 and stop button normal opened contact and in parallel the getting final product of protection normal opened contact three.As Fig. 4.
Fig. 5 is terminal board binding post of the present utility model and control module body assembled relation figure.Dotted line represents that control module body 1 is assembled in the back side of terminal board 2, according to the corresponding line of aforementioned contactor external cabling method, and coil lead 3 and the welding of corresponding voltage coil.
When input has voltage input and adhesive during greater than 85%Ve, when voltage is come in and gone out and big amplitude fluctuations even voltage are occurred to zero the time, control circuit work operate time was from fluctuation trigger 3 seconds, as long as voltage returns to normal value in 3 seconds, contactor still is an attracting state.The no-voltage input, the tripping operation in 3 seconds of delaying time.Under the state of contactor operation, can manual at any time instantaneous tripping operation, also can be at any time by the operate time of protection tripping operation.
In running, if line voltage drops to 50%Ve when following, trigger automatically in the electronic module of the present utility model, be 2.4-2.7s time of delay, if voltage can return to more than the 50%Ve at this moment, time-delay automatically terminates.Voltage can fluctuate zero by rated value between time delay, and permanent magnet contactor can not trip yet, and this has just effectively stablized production system, and does not need on-the-spot any parameter (fluctuation amplitude and duration) to adjust.
If instantaneous shutdown or protection action, stop button or protection normal opened contact have an action, and the timing circuit of locking at once in the module, and produce a negative pulse electric current flows through solenoid, make soft iron core produce one with the permanent magnet polarity same pole.The principle of repelling each other by the same sex, contactor is under the repulsion acting in conjunction between reaction spring, excess of stroke spring and permanent magnet and the soft iron core, the quick tripping of contactor, than the fast 3-10ms of adhesive, so reduce the arcing time, reduce the main contact ablation phenomen of contactor, further improve the appliance life of contactor.
But the utility model had both solved the fluctuation of the 3 seconds big amplitudes of reactance voltage of delaying time even to zero, had solved again manually and protection needs wink moving, overcome should delay time and at any time wink moving this contradiction, make production system more stable, to enterprise's minimizing economic loss.
