Abstract
The utility model discloses a blocking type arc-extinguish chamber, comprising a housing, a static contact seat, a movable contact seat and a spacing rod, wherein the static contact seat comprises a static seat insulator and a static seat conductor bonded together with the static seat insulator, and the movable contact seat comprises a movable seat insulator and a movable seat conductor bonded together with the movable seat insulator. When the movable contact seat is moved to the spacing rod, the static seat conductor is communicated with the movable seat conductor. When the circuit needs to be cut off, the movable contact seat is moved downwardly, the static seat conductor and the movable seat are disengaged, and the same time, the static seat insulator and the movable seat insulator are tightly jointed together, so the static seat conductor is blocked from the movable seat conductor, and the effect of arc extinguishing is reached.
Description
Technical field
The utility model relates to a kind of arc control device, particularly relates to a kind of blocking type arc control device that when circuit breaks off, at once connecting terminal intercepted.
Background technology
Electric arc is a kind of gas discharge phenomenon, and electric arc is the free gas of high temperature high conductivity, and it not only has very big destruction to contact, and makes the time lengthening of open circuit.Therefore; In reality, need carry out arc extinguishing to the occasion that is easy to generate electric arc, and one of measure of arc extinguishing is exactly: improve arc-extinguishing medium; Increase electric simulation strength between arc gap promptly round the arcing contact of mechanical switch, in order to restriction electric arc and help the measure of arc extinction.
In sum, problem demanding prompt solution is to produce corresponding arc-control device to realize above-mentioned rupturing duty through concrete structure.
Summary of the invention
The utility model technical problem to be solved is; A kind of blocking type arc control device are provided, and it effectively intercepts between at once to connecting terminal when circuit breaks off, and significantly improves arc quenching effect; Increase the fail safe of circuit, to prevent circuit is caused the generation of damage and contingency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of blocking type arc control device, and these arc control device comprise: shell, this enclosure are enclosure space; In addition, these arc control device also comprise: static contact seat, and this static contact seat is fixed in said enclosure, comprises the stationary seat insulator and the stationary seat conductor that bond together in this static contact seat; Moving contact seat, this moving contact seat can overlap slides within along rail, comprises the moving seat insulator and moving seat conductor that bond together in this moving contact seat; Gag lever post when the said moving contact seat that moves up, makes that this gag lever post limits said moving contact seat to be continued to move up when said stationary seat conductor was communicated with moving seat conductor.
Further, in the described blocking type arc control device, said enclosure is filled with arc extinguishing gases.
Further, in the described blocking type arc control device, said arc extinguishing gases is a sulphur hexafluoride.
Further, in the described blocking type arc control device, said gag lever post adopts insulating material to process.
The utility model has the advantages that, in the described blocking type arc control device of the utility model, comprise the stationary seat insulator and the stationary seat conductor that bond together in the static contact seat, comprise the moving seat insulator and moving seat conductor that bond together in the moving contact seat.When the said moving contact seat that moves up to the gag lever post place, make said stationary seat conductor and moving seat conductor be communicated with; When the needs open circuit, move down said moving contact seat, the stationary seat insulator fits tightly with moving seat insulator and is in the same place when stationary seat conductor and moving seat conductor break off, makes that stationary seat conductor and moving seat conductor are intercepted, thereby reaches the effect of effective arc extinguishing.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model blocking type arc control device;
Structural representation when Fig. 2 is the connection of the utility model blocking type arc control device;
Structural representation when Fig. 3 is about to break off for the utility model blocking type arc control device.
Embodiment
For further disclosing the technical scheme of the utility model, be described with reference to the accompanying drawings the execution mode of the utility model now.
Fig. 1 is the overall structure sketch map of the utility model blocking type arc control device; Structural representation when the structural representation when Fig. 2 is the connection of the utility model blocking type arc control device, Fig. 3 are about to break off for the utility model blocking type arc control device is among the figure; Comprise:: shell 10; These shell 10 inside are enclosure space, and this enclosure space inside is filled with arc extinguishing gases, such as sulphur hexafluoride; In addition, these arc control device also comprise: static contact seat 11, this static contact seat 11 are fixed in said shell 10 inside, comprise the stationary seat insulator 111 and stationary seat conductor 112 that bond together in this static contact seat 11; Moving contact seat 12, this moving contact seat 12 can overlap 13 slides within along rail, comprises the moving seat insulator 121 and moving seat conductor 122 that bond together in this moving contact seat 12; Gag lever post 14, this gag lever post 14 adopts insulating material to process, and, makes when said stationary seat conductor 112 is communicated with moving seat conductor 122 that the said moving contact seat 12 of these gag lever post 14 restrictions continues to move up when the said moving contact seat 12 that moves up.
Action situation when working below in conjunction with description of drawings the utility model blocking type arc control device.
During work, when the needs open circuit, the said moving contact seat 12 that moves up makes said stationary seat conductor 112 and moving seat conductor 122 be communicated with to gag lever post 14 places; When the needs open circuit; Move down said moving contact seat 12; When stationary seat conductor 112 and moving seat conductor 122 break off; Said stationary seat insulator 111 fits tightly with moving seat insulator 121 is in the same place, and makes that stationary seat conductor 112 and moving seat conductor 122 are intercepted, thereby reaches the effect of effective arc extinguishing.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed execution mode.But the utility model never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection range of the utility model.
