Description

A kind of portable power derailing switch
Technical field
The invention belongs to the switching device field on electronic equipment, particularly relate to a kind of portable power and open Close device.
Background technology
At present, common electric power switch apparatus is mainly electric power switch apparatus, and chopper the most the earliest results from 1885, it was the beginning of a kind of cutter and the combination of overcurrent trip.1905, there is free handle Air-break be born.Since nineteen thirty, along with the progress of science and technology, the discovery of arcing principle and various go out The invention of arc device, has gradually formed mechanism.At the end of the fifties, due to the rise of electronic component, create again Electronic trip unit, to today, due to the universal appearance having had again intelligent circuit breaker of single-chip microcomputer.Common Have low-voltage circuit breaker and vacuum break: low-voltage circuit breaker is for alternating voltage 1200V, DC voltage 1500V Circuit in play break-make, control or the electrical equipment of the effect such as protection.Low-voltage circuit breaker is the important set of electrical equipment industry Become part, be complete sets of basic equipment part in machinery industry, in a power distribution system low-voltage complete switch equipment mainly by Various low-voltage circuit breaker elements are constituted, and low-voltage complete switch equipment is played by function and the performance of low-voltage circuit breaker Vital effect.The 80% of the sent electric energy of generating equipment is above being used by low-voltage circuit breaker distribution 's.Often increasing by 10,000 kW generating equipments, all kinds of low-voltage circuit breakers about needing about 20,000 are matched. In industrial automation system, it is also desirable to the various control panels that are made up of low-voltage circuit breaker, control station, control The products such as device.China's low-voltage circuit breaker industry is afternoon from 1949, is in some repairings, assembling simple appliances work Progressively develop into energy independent design, the industry of production on the basis of factory, have manufacturing enterprise more than 600 to 1979 Family, through, two development peaks in 1990~1991 in 1985~1986, nineteen ninety-five low-voltage circuit breaker row Already there is manufacturing enterprise about 1500.
Electric power switch apparatus is the control parts that power industry is the most important, is one and can make open circuit, makes Current interruptions or make it flow to the electronic component of other circuit, generally comprises contact system, arc-control device and torsion Dynamic device.Switch, when being turned on or off, can make air ionization, produces electric arc, to switch and surrounding Causing damage, the effectiveness therefore switching arc-control device is the critical component solving this problem.With metal gate Sheet carries out arc extinguishing, electric arc is formed multiple short electric arc, eliminates electric arc further, it is possible to reduce electric arc harm, But the corrosion to metal grid is more serious, and arc extinguishing efficiency can be caused for a long time to decline, and impact uses.
But it is high that existing electric power switch apparatus also exists cost, arc quenching method is single and arc extinguishing efficiency Low, in-convenience in use the problem short with service life.
Therefore, a kind of portable power derailing switch of invention seems the most necessary.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of portable power derailing switch, to solve It is high that existing electric power switch apparatus also exists cost, and arc quenching method is single and arc extinguishing efficiency is low, uses Inconvenient and that service life is short problem.A kind of portable power derailing switch, including static contact, shell, Insulating barrier, arc-chutes, upper arc extinguishing grid pieces, lower arc extinguishing grid pieces, upper cover plate, moving contact, pad, even Connecting bolt, lower cover, retainer ring, spring and pedestal, described static contact is just being arranged on moving contact Opposite;Described arc-chutes are arranged on the inside of shell;Described upper arc extinguishing grid pieces is arranged on upper cover plate Bottom;Described lower arc extinguishing grid pieces is arranged on the top of lower cover;Described connecting bolt passes through pad It is arranged on the bottom at lower cover two ends;Described retainer ring is arranged on the left side of spring;Described pedestal It is arranged on the right side of spring.
Described insulating barrier is arranged on the inner side of shell, and described insulating barrier specifically uses insulating resin system Become, can insulate and the effect of arc extinguishing can be played, advantageously reducing maintenance cost, extending and use the longevity Life.
Described upper arc extinguishing grid pieces or lower arc extinguishing grid pieces specifically use thickness to be in 1mm to 2mm Between the low metal-insulator arc extinguishing grid pieces in high two ends, described upper arc extinguishing grid pieces or lower arc extinguishing grid pieces are respectively arranged Having 7, be conducive to improving arc extinguishing efficiency, thus be conducive to reducing maintenance cost further, prolongation makes Use the life-span.
Described pad specifically uses rustless steel annular gasket, is provided with 2 altogether, thus is conducive to Prevent from getting rusty and corroding, reduce maintenance cost further, improve service life.
The invention have the benefit that by insulating barrier, upper arc extinguishing grid pieces, lower arc extinguishing grid pieces and pad Setting, be conducive to improving arc extinguishing efficiency, prevent from getting rusty and corrode, thus be conducive to further reduction Maintenance cost, increases the service life, and increases the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
In figure:
1-static contact, 2-shell, 21-insulating barrier, 3-arc-chutes, the upper arc extinguishing grid pieces of 4-, arc extinguishing under 5- Grid, 6-upper cover plate, 7-moving contact, 8-pad, 9-connecting bolt, 10-lower cover, 11-fixes Ring, 12-spring, 13-pedestal.
