Abstract
The utility model relates to a lightning-protective induce transformer. The utility model consists of a primary coil, a secondary coil, interfering signal isolated components which are arranged in the primary coil and the secondary coil, and a real-time control component. The isolated component is earthed after being connected with the real-time control component and an iron core. The isolated component and the real-time control component response promptly when the primary coil receives signal interference or undergos overvoltage, thus isolating and restraining the signal interference and the thunder.
Description
Technical field
The utility model relates to a kind of transformer, particularly has the transformer of lightning protection effect.
Technical background
Present lightning protection transformer technology mainly reaches lightning-arrest effect by methods such as screen and insulating barrier, employing arrester ground end and transformer case and low pressure winding neutral point common ground are set, the lightning protection grade of this type of lightning protection transformer is not high, and damaged by thunderbolt.
Technology contents
The utility model is by the induction to thunder and lightning and other interference signal, and reacting rapidly produces corresponding demagnetizing current, thereby has improved the lightning protection grade of transformer, and it is not damaged.
The technical solution of the utility model is as follows:
The lightning protection sensor transformer comprises iron core, and primary and secondary coil is mounted with isolated component between primary coil and the secondary coil, is characterized in: isolated component also is in series with real-time control element, and isolated component is with control element, iron core are connected back ground connection in real time.
Above-described lightning protection sensor transformer, isolated component are last circle is made electric upper shed with Copper Foil solenoid coils.
Above-described lightning protection sensor transformer, control element is by electric capacity, the inductance of voltage and frequency sensitive are formed resonant circuit and in parallel with the voltage clamp device in real time.
Above-described lightning protection sensor transformer, voltage clamp device in the control element is selected two-way clamper diode component for use in real time, or piezo-resistance or anti-surge lightning arrester or bi-directional voltage stabilizing pipe, or unidirectional voltage-stabiliser tube, as select for use unidirectional voltage-stabiliser tube then to should be even number, polarity is opposite, is connected in parallel, and the use of element is decided on use occasion.
The utility model is because connected on the line isolated component and real-time control element, by be configured in isolated component between the primary and secondary coil, with control element acting in conjunction in real time, isolate and suppress thunder and lightning and other interference signal that supply transformer is passed through in attempt, can on apart from the network in this transformer certain limit, reduce thunder and lightning or other overvoltage of induction, significantly improve the lightning protection grade of network, reduce the probability and the destructiveness of damage to crops caused by thunder.
Substantive distinguishing features of the present utility model and progress are:
Can be used on distribution transformer and the power transformer, prevent that effectively overvoltage from closing the output voltage that disturbs secondary coil by the electromagnetic coupling between the primary and secondary, thereby play the electric equipment of protection primary side.
Isolated component and real-time control element are set between the primary and secondary coil, thereby, improve the lightning protection grade by protective reaction is made in the induction of thunder and lightning and other interference signal rapidly.
Description of drawings
Fig. 1 is the structural representation of the utility model lightning protection sensor transformer.
Embodiment
As shown in Figure 1, lightning protection transformer is by iron core 1, secondary coil 2, isolated component 3 and primary coil 4 constitute, isolated component 3 is placed between primary coil 4 and the secondary coil 2, real-time control element 5 of isolated component 3 series connection and ground connection, control element 5 is by electric capacity in real time, the spacing device 6 of inductance and voltage composes in parallel, electric capacity, inductance is a resonant circuit, isolated component 3 is cylindrical layer windings of special construction, and last circle is made the cylindrical shape of electric upper shed with Copper Foil, and the spacing device 6 of voltage is selected two-way clamper diode component for use, or piezo-resistance or anti-surge lightning arrester or bi-directional voltage stabilizing pipe, or unidirectional voltage-stabiliser tube, as select for use unidirectional voltage-stabiliser tube then to should be even number, polarity is opposite, be connected in parallel, the use of element is decided on use occasion.
The utility model can carry out real-time tracking to thunder and lightning and other interference signal, when lightning wave or one appearance of other interference signal, almost side by side in isolated component, produce and the corresponding demagnetizing current of disturbing wave, make network at this transformer place node to lightning wave and other interference signal as ground connection, its residual voltage has only below 10% of output voltage.
