Abstract
The utility model discloses a permanent magnet magnetron monitoring device, which belongs to the technical field of magnetron monitoring. The utility model has technical points that the device comprises a magnetron, a high-voltage converter, and a capacitor and a diode which are connected between the anode of the magnetron and the high-voltage winding of the high-voltage converter in a circuit in sequence, wherein a current transformer is also in circuit connection between the magnetron and the high-voltage winding of the high-voltage converter, and the current output end of the current transformer is connected with a filter circuit and a master control unit in the circuit in sequence. The utility model has simple structure, safe use and low cost and is suitable for monitoring the magnetron.
Description
Technical field
The utility model relates to a kind of supervising device, more particularly, relates in particular to a kind of magneto magnetron supervising device.
Background technology
At present, domestic the detecting of being made up of small-sized magnetron by resistor of high-power its anode voltage of tunnel type micro wave firing equipment finished, the high pressure that surpasses 5500V when resistor is opened a way will be guided in the control circuit, cause the badly damaged of control circuit, and it is also relatively more expensive to be sampled as the expense that magnetron sets up data bank with resistor, causes the increase of production cost.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, safe in utilization, the magneto magnetron supervising device that cost is low.
The technical solution of the utility model is achieved in that a kind of magneto magnetron supervising device, comprise magnetron, high-voltage converter, circuit is connected capacitor and the diode between magnetron and the high-voltage converter high pressure winding in regular turn, wherein, go back circuit between described magnetron and the high-voltage converter high pressure winding and be connected with current transformer, the current output terminal of current transformer circuit in regular turn connects filtering circuit and main control unit.
Above-mentioned a kind of magneto magnetron supervising device, wherein said main control unit also is connected with storer.
After the utility model adopts said structure, to detect magnetron voltage by resistor originally changes into by current transformer detection magnetron current, the high pressure above 5500V can be born in current transformer high-low pressure both sides, in the cost-effective while, has also improved security.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Among the figure: magnetron 1, high-voltage converter 2, capacitor C, diode D, current transformer 3, filtering circuit 4, main control unit 5, storer 6.
Embodiment
Consult shown in Figure 1, a kind of magneto magnetron supervising device of the present utility model, comprise magnetron 1, high-voltage converter 2, circuit is connected capacitor C and the diode D between magnetron 1 anode (perhaps negative electrode) and the high-voltage converter 2 high pressure windings in regular turn, go back circuit between magnetron 1 anode and the high-voltage converter 2 high pressure windings and be connected with current transformer 3, the current output terminal of current transformer 3 circuit in regular turn connects filtering circuit 4 and main control unit 5, and main control unit 5 also is connected with storer 6.
Work as energized, high pressure winding in the high-voltage converter 2 obtains ac high-voltage after capacitor C current limliting and diode D rectification high direct voltage adds to magnetron 1 anode (perhaps negative electrode), magnetron 1 operate as normal, this moment, current transformer 3 detected anode (perhaps negative electrode) electric current of magnetron 1, feeding back to 5 pairs of magnetrons 1 of main control unit after wave circuit 4 filters after filtration monitors, the current data that detects simultaneously is sent to storer 6 storages, sets up magnetron 1 data bank.
