Abstract
The utility model relates to an anti-inductive-thunder and fuse-blowout flickering-light indicating transformer, wherein a ceramic air-discharging pipe is installed on a circuit board, connected in parallel with a voltage-sensitive resistor connected in series with a fuse, led out through two leads and respectively connected in parallel with two end points connected with a primary coil of a medium-small transformer and a 220V power supply; and in addition, a group of flickering devices are installed on the same circuit board, i.e. a rectifying diode is connected in series with a resistor, connected in series with a relaxation oscillator which is formed in the way that a capacitor is connected in parallel with a bidirectional trigger diode and then connected in series with a light-emitting diode, led out through two leads and respectively connected in parallel with both ends of the fuse of the medium-small transformer for intercepting an inductive thunder, absorbing energy and protecting electrical apparatuses, and when the fuse is blown out and the primary coil of the transformer is still normal, a flickering indicating signal is sent out.
Description
Affiliated technical field:
The utility model be a kind of anti-induction thunder, blowout transformer primary coil still just often, can send the middle-size and small-size low-frequency transformer of fast blink light.
Background technology:
Existing middle-size and small-size low-frequency transformer, primary coil all do not have anti-induction thunder, blowout indicating device, are not enough.Thunderbolt mainly occurs on the high-tension bus-bar and large-scale open-air transformer of power supply administration, scurry in the low voltage electric network but still have part induction thunder, middle-size and small-size low-frequency transformer space is limited, and consider cost, primary coil enamelled wire (copper cash) is much thinner than secondary, causes the damage of the middle-size and small-size low-frequency transformer more than 90% all to occur in primary coil.Add that this device can effectively protect primary coil, and blowout, the transformer passage of scintillation light indication that still just often can send Fast transforms.
Summary of the invention:
In order to prevent to respond to the destruction of thunder centering miniature transformer primary coil, and middle-size and small-size transformer blowout, the transformer passage of scintillation light indication of still just often sending Fast transforms.
The technical scheme that the utility model adopted is: the ceramic air discharge tube that 800 volts of conducting voltage are installed on a wiring board is connected in series the piezo-resistance parallel connection of 1200 volts of fuse conducting voltage with one, draw with two leads, two end points that join with middle-size and small-size transformer and 220V power supply and connecing respectively, one group of flashing device is installed on same wiring board in addition, i.e. rectifier diode IN4007 rectification, be connected in series a 150K Ohmic resistance step-down current limliting, serial connection is by " relaxation oscillator " that light-emitting diode constitutes of bidirectional trigger diode series connection of the electrochemical capacitor breakover voltage 20-40V in parallel of one the 4.7 withstand voltage 50V of ц F, draw with two leads, respectively with the fuse two ends of middle-size and small-size transformer and connect.Pottery air discharge tube, piezo-resistance are under normal voltage, and resistance is in open-circuit condition greater than 1,000 ten thousand ohm, can be to any influence of various parameter generating of transformer.When running into greater than 800V less than the induction thunder of 1200V, ceramic air discharge tube conducting makes the tripping operation of power supply air switch, the transformer blowout; When run into greater than or when being far longer than the induction thunder of 1200V; the conducting of pottery air discharge tube, piezo-resistance conducting, blowout, transformer blowout, the tripping operation of power supply air switch, they absorb the energy of high pressure surge jointly; protected transformer effectively, made electrical equipment not impaired.When the transformer fuse is intact, fuse two ends and the flare light device that connects, dead electricity is not worked, work as blowout, and when transformer is intact, electric current is through rectifier diode IN4007 rectification, 150K Ohmic resistance step-down current limliting, (it is right that both positive and negative polarity must connect by the electrochemical capacitor filtering of one the 4.7 withstand voltage 50V of ц F for serial connection, otherwise can not glimmer) (it is right that both positive and negative polarity must connect for light-emitting diode of bidirectional trigger diode series connection of a breakover voltage 20-40V in parallel, otherwise do not work) " relaxation oscillator " that constitute, the primary coil of transformer constitutes the loop, make light-emitting diode send passage of scintillation light fast, indicating fuse blows, flow through about 2 milliamperes of the electric current of flicker indicating device, can not constitute security threat, can not make electrical work yet the maintenance personal, very safe.
The beneficial effects of the utility model are: exempt to be smashed when making middle-size and small-size low-frequency transformer meet with the induction thunder, and transformer blowout, transformer just often can be sent passage of scintillation light indication fast
