Description

Осуществление достаточно больших контактных поверхностей в выключател х дл  токов большой силы, особенно при низком напр жении, св зано с значительными затруднени ми, заключающимис , например, в сложности точной пришлифовки поверхностей друг к другу, возможном местном загр знении этих поверхностей и т. д. Кроме того, даже при точно пришлифованных друг к другу контактных поверхност х, они без трени  накладываютс  друг на друга, может иметь место, как известно,  вление так называемого „кажущегос  сцеплени , причиной которого  вл етс  тонка  пленка воздуха, наход ща с  между поверхност ми и обуславливающа  высокое сопротивление и даже изол цию.The implementation of sufficiently large contact surfaces in switches for high-current currents, especially at low voltages, is associated with considerable difficulties, for example, in the difficulty of sanding surfaces to each other, possible local contamination of these surfaces, etc. In addition, even when the contact surfaces are precisely ground to each other, they are superimposed without friction on each other, as is well known, the phenomenon of the so-called apparent adhesion, caused by Onka air film, locates-adhesive between the surfaces and obuslavlivayuscha high resistance and even insulation.

Следовательно, в выключател х с твердыми контактными част ми контактньте поверхности нужно притирать и прижимать друг к другу под больший давлением или даже делать их по возможности шероховатыми.Consequently, in switches with hard contact parts, contact surfaces must be ground and pressed against each other under greater pressure, or even roughed as much as possible.

Согласно предлагаемому изобретению, необходимость большого давлени  и особого движени  дл  создани  трени  между контактными поверхност ми выключател  устран етс  путем прокладывани  между этими контактными поверхност ми проволочной сетки. При нада вливании одной контактной поверхностк на другую сетка с трением прижимаетс  к контактным поверхност м, прорыва : воздушную пленку.According to the present invention, the need for high pressure and special movement to create friction between the switch contact surfaces is eliminated by laying a wire mesh between these contact surfaces. When an infusion of one contact surface is applied to another, the mesh is pressed against the contact surfaces with a friction breakthrough: an air film.

На чертеже схематически изображен предлагаемый выключатель.The drawing schematically shows the proposed switch.

Между параллельно плоскими кон тактными поверхност ми контактов а и cZj, соединенных с проводами сети си Ci, расположена металлическа  сетка &.. Сетку можно прикрепл ть к одному из: контактов и замен ть по мере надобности.. Ход выключател  и давление могут быть весьма невелики. Предлагаемый выключатель может быть применен, например , дл  переключени  рабочего тока в сварочных электроаппаратах, которое, как правило, производитс  при разрыве. первичной цепи.Between the parallel flat contact surfaces of the contacts a and cZj, connected to the wires of the network Ci, there is a metal grid & .. The grid can be attached to one of: contacts and replaced as needed. are small. The proposed switch can be used, for example, to switch the operating current in electric welding machines, which, as a rule, is produced at break. primary circuit.
