Electric power switch apparatus is the control assembly of power industry outbalance, is one and can makes open circuit, makes current interruptions or make its electronic component that flows to other circuit, generally comprises contact system, arc-control device and wrench device.Switch, when opening or cutting out, can make air ionization, produces electric arc, and to switch and around cause damage, so the validity of switch arc-control device is the critical component addressing this problem.With metal gate sheet, carry out arc extinguishing, electric arc is formed to a plurality of short electric arc, further eliminate electric arc, can reduce electric arc harm, but comparatively serious to the corrosion of metal gate sheet, can cause arc extinguishing decrease in efficiency for a long time, impact is used.
But it is high that existing electric power switch apparatus exists cost, arc quenching method is single and arc extinguishing efficiency is low, uses short problem in inconvenient and useful life.
Therefore, invent a kind of portable power derailing switch and seem very necessary.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of portable power derailing switch, to solve existing electric power switch apparatus, to exist cost high, and arc quenching method is single and arc extinguishing efficiency is low, uses short problem in inconvenient and useful life.A portable power derailing switch, comprises fixed contact, shell, insulating barrier, arc control device, upper arc extinguishing grid pieces, lower arc extinguishing grid pieces, upper cover plate, moving contact, pad, connecting bolt, lower cover, retainer ring, spring and pedestal, described fixed contact is arranged on the right opposite of moving contact; Described arc control device are arranged on the inside of shell; Described upper arc extinguishing grid pieces is arranged on the bottom of upper cover plate; Described lower arc extinguishing grid pieces is arranged on the top of lower cover; Described connecting bolt is arranged on the bottom at lower cover two ends by pad; Described retainer ring is arranged on the left side of spring; Described pedestal is arranged on the right side of spring.
Described insulating barrier is arranged on the inner side of shell, and described insulating barrier specifically adopts insulating resin to make, and can insulate and can play the effect of arc extinguishing, is conducive to reduce maintenance cost, increases the service life.
It is the low metal-insulator arc extinguishing grid pieces in high two ends, centre of 1mm to 2mm that described upper arc extinguishing grid pieces or lower arc extinguishing grid pieces specifically adopt thickness, described upper arc extinguishing grid pieces or lower arc extinguishing grid pieces are respectively provided with 7, be conducive to improve arc extinguishing efficiency, thereby be conducive to further reduce maintenance cost, increase the service life.
Described pad specifically adopts stainless steel annular gasket, is provided with altogether 2, thereby is conducive to prevent from getting rusty and corroding, and further reduces maintenance cost, improves useful life.
