Abstract
The utility model provides an SF6 arc-extinguishing chamber. Gas is filled in an insulating shell body; both ends of the insulating shell body are provided with two electrodes, are additionally provided with contact heads, and are connected with the contact heads of the two electrodes by a movable electric conducting pipe with an electric magnet. The middle part of the outer wall of the shell body is provided with a closing coil and an opening coil. When the closing coil and the opening coil are respectively energized, the movable electric magnet, the movable electric conducting pipe and a movable arc contact head (an ejector nozzle) are sucked to switch off and switch on a static arc contact head. When the utility model is switched off, compressed SF 6 is ejected from the movable arc contact head (the ejector nozzle), the electric arc is extinguished, and a circuit is switched off.
Description
Affiliated technical field:
The utility model relates to arc control device, especially a kind of SF that fills
6The arc control device of insulating gas.
Background technology:
In the prior art, technique known is to utilize the SF with good insulation performance
6The circuit breaker of gas manufacturing has been applied among the circuit of high pressure, superhigh pressure and each electric pressure of ultra high voltage.The arc quenching chamber structure complexity of such circuit breaker, bulky heaviness, actuating power is big, and this is the subject matter that prior art exists.
Summary of the invention:
The purpose of this utility model is at the deficiencies in the prior art, and a kind of SF that provides
6The arc control device technical scheme.This scheme simple in structure implemented easily.
This programme is realized by following measure:
SF
6Arc control device include cylindrical insulation shell, on two electrodes of two end cap, be respectively equipped with contact, the middle part is to be the moving conductive pipe of one with electromagnet group, at the middle part of shell closing coil and switching winding are arranged, when two coils are switched on respectively, electromagnet (piston) will with moving conductive pipe move left and right, realize that the pass of circuit is closed.When cut-offfing state, electromagnet (piston) moves right SF
6Gas is compressed and flow to moving conductive tube hub hole by each pore to be blown out electric arc when the quiet arc contact is separated with moving arcing contact.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to SF in this scheme
6Respectively be provided with two electrodes that are connected as a single entity with contact on the two end cap of arc control device.The moving conductive pipe that is connected as a single entity with electromagnet (piston) is arranged between two contacts.At the shell middle part switching winding and closing coil are arranged.When switching on respectively, realize by two coils the break-make of circuit.When the separating brake process, because switching winding energising, at this moment the moving conductive pipe moves to right the moving arcing contact (spout) to the moving conductive pipe is separated with the quiet arc contact, at this moment because by the gas of electromagnet (piston) compression, from each pore, enter in the moving conductive pipe, by moving arcing contact (spout) ejection electric arc is blown out then, made it arc extinguishing.
Said structure is very simple, and processing easily.Utilize the circuit breaker of this programme manufacturing can simplify more than 90%, and actuating power is little, saves production cost, and compares with it to have substantive distinguishing features and progress than the mechanical structure of like product.The beneficial effect of its enforcement also is conspicuous.
Description of drawings:
In the accompanying drawing, 1 is in the moving arcing contact (spout), and 2 is left electrode, 3 is left end cap, and 4 is quiet main contact, and 5 is the quiet arc contact, 6 is spacing for closing a floodgate, and 7 is electromagnet (piston), and 8 is closing coil, 9 is switching winding, 10 is the moving conductive pipe, and 11 is fixed contact, and 12 is right end cap, 13 is right electrode, and 14 is pore.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is carried out lock state in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing this programme SF as can be seen
6Arc control device fill SF at inner chamber
6The two ends of the cylindrical seal insulation shell (15) of gas are provided with left end cap (3) and right end cap (12), left end cap (3) is solidified as a whole with left electrode (2), the right-hand member of left side electrode (2) is quiet main contact (4) and quiet arc contact (5), be provided with electromagnet (piston) (7) at the middle part of moving conductive pipe (10), left end is a moving arcing contact (spout) (1), right end cap (12) is gone up intrinsic right electrode (13), the left end of right electrode (13) is fixed contact (11), and the right-hand member of fixed contact (11) and moving conductive pipe (10) is slidingly connected.There are closing coil (8) and switching winding (9) in middle part, surface at insulation shell.When closing coil (8) was switched on, electromagnet (piston) (7) drive contact tube (10) moved to left and makes its moving arcing contact (1) contact energising with quiet arc contact (5) with quiet main contact (4), and this is a "on" position.When switching winding (9) was switched on, electromagnet (piston) (7) drove contact tube and moves to right, and at this moment electromagnet (piston) (7) is with SF
6Gas compression makes it to enter in the moving conductive pipe by pore (14), produces electric arc when moving conductive pipe (10) continues to move to right to moving arcing contact (spout) (1) when separating with quiet arc contact (5), this moment compressed SF
6Gas is blown out electric arc from moving arcing contact (spout) (1) ejection.
This programme can be used for high voltage switchgear, and the single-phase or three phase mains of flame-proof switch equipment and low-pressure high-power because actuating power is little, especially is useful for synchronized breaker.
