Brief description of the drawings
Fig. 1 is circuit block diagram of the invention.
Fig. 2 is the circuit diagram of leadage circuit.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, the micro-grid connection switch auxiliary arc extinction device with control device of releasing automatically, including electric current are mutual
Sensor, can not control rectifying circuit, leadage circuit and damping resistance R.
Attachment structure is as follows：The primary side of current transformer is connected with PCC, and PCC implication is point of common coupling, secondary side
With can not the input of control rectifying circuit be connected, it is described can not the output end of control rectifying circuit and the input of leadage circuit connect
Connect, the output end of the leadage circuit is connected with damping resistance R, the damping resistance R ground connection.
It is above-mentioned can not control rectifying circuit be mainly made up of diode, the circuit is available circuit, is not chatted in detail here
State.
Above-mentioned leadage circuit is as shown in Fig. 2 including electric capacity C, IGBT and first resistor R1；First resistor R1 one end difference
It is connected with electric capacity C one end and IGBT gate pole, IGBT colelctor electrode is connected with the first resistor R1 other end, IGBT hair
Emitter-base bandgap grading external damping resistance R, electric capacity the C other end and first resistor R1 and the external uncontrollable rectification of tie point of IGBT colelctor electrodes
Circuit.
The course of work of said apparatus is as follows：
After PCC disconnections, the electric current I on transmission line of electricity increases suddenly, works as I>During Im（Im is action current）, Current Mutual Inductance
Device secondary side produce a higher voltage, by can not control rectifying circuit leadage circuit electric capacity C produce high voltage
IGBT cut-in voltage is met or exceeded, makes IGBT open-minded, so that electric current flows through from damping resistance R, shunting action is finally reached,
The electric current in transmission line of electricity is quickly reduced, reach arc extinguishing purpose.When electric current is less than Im in circuit, IGBT is closed automatically, no
Power grid energy is lost.
Power network electric energy will not be lost when micro-capacitance sensor is normally run for said apparatus, and can automatically restore to after arc extinguishing power network
Normal run time behaviour, meets the demand of energy-conservation, while compared with traditional device, low cost, technical requirements are not high, maintenance expense
With low.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
