Description
Technical field
The present invention relates to a kind of high-voltage electric connector, more particularly to a kind of magnetic quenching formula high-voltage electric connector.
Background technology
When plugging HVDC connector, maximum risk is exactly injury of the electric arc to connector.Work as connector socket
With the corresponding terminal in female seat very close to (the air gap very little of male seat terminal and female seat corresponding terminal when not contacting but
When), if be not now in advance electrically turn off HVDC, very big electricity between male seat terminal and female seat corresponding terminal be present
Pressure difference, cause the air of near gaps to be ionized, form electric current and flow through the air gap, and produce electric arc.When the air gap mistake
When big, the atmospheric density being ionized is insufficient, and electric arc will extinguish.The generation of electric arc, it is easy to cause connector socket terminal
Burn with the terminal of female seat or be even fused together.
It is exactly before HVDC connector is plugged, first by the power-off of feeder ear to solve electric arc most straightforward approach.
But this practice relies on very much the correct action of operator, and risky.Therefore just have and much possess foolproof function or hot plug work(
The HVDC connector of energy is devised.
Magnetic quenching is then a kind of method that can accelerate arc extinction.When electric arc produces, have electric current and flow through connector public affairs
The air gap of seat terminal and female seat corresponding terminal.If now there is an externally-applied magnetic field, the electric current in flowing deviates.And
The gap that the skew of current path is equal to male seat terminal and female seat corresponding terminal increases, and also accelerates the extinguishing of electric arc.
In traditional two-terminal DC high voltage connector, only live wire and ground wire.An only live wire, and ground wire is then
To connect the ground wire of feeder ear and receiving end, therefore electric arc is only occurred between male seat and female seat fire line terminal.It is existing
The high-voltage electric connector of magnetic quenching, it is exactly to solve to occur in male seat fire as CN103094733A and CN103326177A is main
Arcing problems between line terminals and female seat fire line terminal.
In high-voltage direct current, the distance of feeder ear power supply and receiving end equipment may be far, therefore feeder ear power supply
The ground wire of ground wire and receiving end equipment to there is current potential (voltage) poor.The only two-terminal DC high-voltage of live wire and ground wire
Connector just has electric current and flowed on ground wire.In order to solve this problem, the conventional HVDC connector of another kind is exactly
By the way of independent grounding, that is, ground wire is independent.The high voltage direct current of feeder ear enters by the plus end of connector
Enter the equipment of receiving end, then feeder ear is returned to by the negative terminal of connector.Meanwhile the ground wire of the feeder ear then ground with receiving end
Line gets up through connector linking.In the case, HVDC connector has three joints.Plus end is by feeder ear power supply
High voltage direct current is input to receiving end equipment；Negative terminal flow back into feeder ear power supply by the high voltage direct current of receiving end equipment；
Ground wire terminal is then linking the ground wire of feeder ear power supply and receiving end equipment.In other words, when this three terminals HVDC
For connector in hot plug, positive and negative terminals can all have high voltage direct current flowing, and produce electric arc.
As shown in fig. 6, (plus end 1, negative terminal 2, the plus end sense of current in existing three terminals HVDC connector
11, the negative terminal sense of current 21, magnetic direction 3, current offset direction 4) electric arc can be produced in positive and negative terminals.Using magnetic blowout
During arc, electric arc moving direction must just cause two electric arcs more from more remote better.Due to there is 110 degree between positive and negative two terminals
Angle, therefore the direction 3 in magnetic field as shown, must can just make the moving direction of electric arc to allow two electric arcs more from more remote.If
Using CN103094733A the and CN 103326177A practice, then have the disadvantage that：The putting position of (1) two pair of magnet is limited
In male seat moulding, and interfering can not avoiding two magnet.(2) it is difficult to be uniformly distributed and intensity in first arc zone
Consistent magnetic field, and the materially affect of these shortcomings is exactly that slow down arc extinguishing speed.
