Abstract
The utility model discloses an arc extinguishing device of a high-voltage direct-current relay. Process holes are left on a closed cavity which is arranged outside and around bridge contact points, which can facilitate vacuum pumping or inert gas filling and help reduce arcing. Strong magnets are placed in independent magnet cavities, an isolation layer is formed between the strong magnets and an arcing space, and the strong magnets are stable in position. An arc isolation cover capable of heat and temperature insulation is arranged between arcing points and the magnets and the arc isolation cover can serve as another isolation layer so that the magnets cannot be demagnetized, pollution generated due to arcing is isolated, and harmful effects of pollutants on the product performance are avoided. Therefore, effective arc extinguishing can be realized, and the arc extinguishing device is simple in structure and easy in processing and cannot be demagnetized.

Summary of the invention
The utility model purpose is to provide a kind of arc-control device of high voltage direct current relay, and it is good, simple for structure that it has an arc quenching effect, handling ease, the advantage such as can not demagnetize.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of arc-control device of high voltage direct current relay, in the high voltage direct current relay, be provided with bridging contact, described arc-control device be included in the bridging contact periphery closed cavity, be built up in closed cavity four independently magnet bore, be placed on four kicker magnets in magnet bore respectively, four magnet bore be distributed in the both sides of bridging contact and in pairs, form two relatively independent high-intensity magnetic fields perpendicular to the arcing direction.
The utility model forms two relatively independent high-intensity magnetic fields perpendicular to the arcing direction in two arcing spaces that are parallel to the bridging contact contact-making surface, thereby can shorten fast the spray arc, extinguishes arcing, improves arc quenching effect, and simple for structure being easy to realized.
For technique scheme, the inventor also has further volume to optimize embodiment.
As optimization, described arc-control device also comprises arc insulating cover, and arc insulating cover covers bridging contact and is seated in the high-intensity magnetic field of kicker magnet formation.Thereby the utility model relies on arc insulating cover and the pollution of arcing and generation thereof is controlled in cavity to the arc quenching effect that reaches good, and isolated temperature, makes magnet can not demagnetize, and further improves arc quenching effect.
As optimization, closed cavity is provided with for steam vent, in closed cavity, making the full environment of vacuum or inert gas.
Than solution of the prior art, the utility model advantage is:
In the arc-control device of the described high voltage direct current relay of the utility model, leave fabrication hole on the closed cavity arranged outside bridging contact, be convenient to vacuumize or be filled with inert gas, be conducive to reduce arcing; And kicker magnet is placed on separately independently in magnet bore, with the arcing space, one deck separator has just been arranged, and position stability; Between arcing point and magnet, also have arc insulating cover, can heat insulation thermal insulation, many again separators, make magnet can not demagnetize, and isolates simultaneously the pollution that arcing produces, and avoids pollutant to produce harmful effect to properties of product.Therefore, can realize effective arc extinguishing, and simple for structure, handling ease, can not demagnetize.
