Description

Magnetic quenching formula high-voltage electric connector
Technical field
The utility model is related to a kind of high-voltage electric connector more particularly to a kind of magnetic quenching formula high-voltage electric connectors.
Background technology
When plugging high voltage direct current connector, maximum risk is exactly injury of the electric arc to connector.Work as connector base 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 at this time in advance electrically turn off high voltage direct current, there is very big electricity between male seat terminal and female seat corresponding terminal Pressure difference causes the air of near gaps to be ionized, and forms electric current and flows through the air gap, and generate 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 lead to connector base terminal It burns with the terminal of female seat or is even fused together.
It is exactly before high voltage direct current connector is plugged to solve electric arc most straightforward approach, first closes the power supply of feeder ear. But this practice relies on very much the correct action of operator, and risky.Therefore just have and much have foolproof function or hot plug work( The high voltage direct current connector of energy is devised.
Magnetic quenching is then a kind of method that can accelerate arc extinction.When electric arc generates, have electric current and flow through connector public affairs The air gap of seat terminal and female seat corresponding terminal.If there is an externally-applied magnetic field at this time, the electric current in flowing deviates.And The offset of current path is equal to male seat terminal and the gap of female seat corresponding terminal increases, and also accelerates the extinguishing of electric arc.
In traditional two-terminal DC high voltage connector, only firewire and ground wire.An only firewire, 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 is exactly to solve to be happened at male seat as CN103094733A and CN 103326177A are main Arcing problems between fire line terminal 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 firewire and ground wire Connector just has electric current and is flowed on ground wire.In order to solve this problem, another common high voltage direct current connector is exactly By the way of independent grounding, that is, ground wire is independent.The high voltage direct current of feeder ear by connector plus end into Enter the equipment of receiving end, feeder ear is returned to using the negative terminal of connector.Meanwhile the ground wire of feeder ear then with the ground of receiving end Line gets up through connector linking.In the case, high voltage direct current connector can be there are three connector.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 high voltage direct current For connector in hot plug, positive and negative terminals can all have high voltage direct current flowing, and generate electric arc.
As shown in fig. 6, (plus end 1, negative terminal 2, plus end current direction in existing three terminals high voltage direct current connector 11, negative terminal current direction 21, magnetic direction 3, current offset direction 4) electric arc can be generated in positive and negative terminals.Using magnetic blowout During arc, electric arc moving direction must just so that the two electric arcs the better from more more remote.Since there are 110 degree between positive and negative two terminals Angle, therefore the direction 3 in magnetic field as shown, can must just make the moving direction of electric arc that can allow two electric arcs more from more remote.If Using the practice of CN103094733A and CN 103326177A, then have the disadvantage that:The placement position of (1) two pair of magnet is limited In male seat moulding, and interfering with each other can not avoiding two betweens of 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 to slow down arc extinguishing speed.
