Abstract
The invention includes case of columnar sealed insulation tube with its cavity being as vacuum or filled with inert gases. Upper and lower poles outside the case are connected inside the cavity. There is a movable pole with iron core being fixed on it in the case. The upper pole is connected to upper spring contact inside case; upper part of the movable pole is sliding connected to the upper spring contact; lower pole is connected to lower spring contact. There are winding for detaching switch, and winding for closing switch enclosed outside the case. When the iron core is aligned to the closing winding, the movable pole is inserted to the lower spring contact; when the iron core is aligned to the detaching winding, the movable pole is detached from the lower spring contact. Thus, ducting the detaching winding and closing winding is carried out at zero voltage. Therefore, no spark is generated when windings are conducted.
Description
Affiliated technical field:
What the present invention relates to is a kind of mains switch, especially a kind of electromagnetic switch tube that does not produce electric arc when being used for mains switch.
Background technology:
In the prior art, technique known is by the applicant application and the 02267389X patent of being authorized by China Intellectual Property Office, this patent disclosure a kind of little power consumption do not have the technical scheme of arc mercoid switch and control circuit, this scheme can solve the problem of mains switch generation electric arc when outage effectively, its weak point is that the structure of switch is complicated, also need mercury, be difficult for adjusting and making.
Summary of the invention:
Purpose of the present invention is exactly at the existing in prior technology deficiency, and a kind of technical scheme of electromagnetic switch tube is provided, and the switch of this scheme does not adopt mercury to do contact, and structure is also simple, implements and install adjustment easily.
This programme is realized by following technical measures: the electromagnetic switch tube of this programme, mainly include the cylindrical seal insulated tube housing of inner chamber vacuum or filling with inert gas, the top electrode and the bottom electrode that communicate with the tube shell inner chamber are arranged outside tube shell, float electrode is arranged in tube shell, be fixed with iron core on this float electrode, to be described top electrode be connected with last spring contact in the tube shell characteristics of this programme, and the top of described float electrode and last spring contact are slidingly connected, following spring contact in described bottom electrode and the tube shell is connected, outside tube shell, around tube shell switching winding and closing coil are arranged, when iron core aligns with closing coil, in the spring contact, when iron core alignd with switching winding, float electrode broke away from spring contact down under float electrode was inserted.The concrete technical characterstic of this programme also has, and also is fixed with guide rod and passes iron core on the end wall of described tube shell inner chamber one end, and iron core can move axially along guide rod.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because spring contact is connected in this scheme in top electrode and the tube shell of electromagnetic switch tube, following spring contact in bottom electrode and the tube shell is connected, and the top of float electrode and last spring contact are slidingly connected.Around tube shell switching winding and closing coil are arranged, when iron core alignd with closing coil, float electrode was inserted in the following spring contact, when iron core aligns with switching winding, float electrode breaks away from spring contact down, and has guide rod to pass iron core at the tube shell inner chamber, and iron core can move by guide rod is directed.This structure, when closing coil has electricity, float electrode is connected simultaneously with upper and lower spring contact, the upper and lower electrode of electromagnetic switch tube is connected, the electromagnetic switch tube switch closes a floodgate, and when switching winding had electricity, float electrode was separated with following spring contact, the upper and lower electrode of electromagnetic switch tube disconnects electromagnetic switch tube switch separating brake.As seen the electromagnetic switch tube of this structure is only controlled the switching of electromagnetic switch tube by closing coil and switching winding, and its structure is very simple, and is easy to processing.The closing coil of this electromagnetic switch tube and switching winding combine with no arc control circuit, make closing coil and switching winding instantaneous what must conduct, all be under the zero potential of zero phase, to carry out, therefore, the conducting of electromagnetic switch tube is closed a floodgate and the outage separating brake also all is to carry out when zero phase, so the conducting of electromagnetic switch tube is closed a floodgate and the outage separating brake just can not produce spark yet, does not have the effect of arc when having reached combined floodgate and separating brake.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the specific embodiment of the invention.
1 is bottom electrode among the figure, and 2 is guide rod, and 3 are following spring contact, and 4 is unshakable in one's determination, and 5 is float electrode, and 6 is last spring contact, and 7 is top electrode, and 8 is tube shell, and 9 is switching winding, and 10 is closing coil.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing 1 as can be seen, the electromagnetic switch tube of this programme has the cylindrical seal insulated tube housing (8) of inner chamber vacuum or filling with inert gas, the top electrode (7) and the bottom electrode (1) that communicate with tube shell (8) inner chamber are arranged outside tube shell (8), float electrode (5) is arranged in tube shell (8), be fixed with iron core (4) on this float electrode (5), last spring contact (6) in the described top electrode of this programme (7) and the tube shell (8) is connected, and the top of described float electrode (5) and last spring contact (6) are slidingly connected, following spring contact (3) in described bottom electrode (1) and the tube shell (8) is connected, outside tube shell (8), around tube shell (8) switching winding (9) and closing coil (10) are arranged, at iron core (4) and closing coil (10) when aliging, float electrode (5) is inserted in the following spring contact (3), electromagnetic switch tube closes a floodgate, when aliging, float electrode (5) breaks away from spring contact (3) down, electromagnetic switch tube separating brake at iron core (4) and switching winding (9).Also be fixed with guide rod (2) and pass iron core (4) on the end wall of described tube shell (8) inner chamber one end, iron core (4) can move axially along guide rod (2).As seen the electromagnetic switch tube of this structure, only control the logical and disconnected of electromagnetic switch tube by closing coil (10) and switching winding (9), closing coil of this electromagnetic switch tube (10) and switching winding (9) combine with no arc control circuit, make closing coil (10) and switching winding (9) instantaneous what must conduct, all be under the zero potential of zero phase, to carry out, therefore, the conducting of electromagnetic switch tube is closed a floodgate and the outage separating brake also all is to carry out when zero phase, so the conducting of electromagnetic switch tube is closed a floodgate and the outage separating brake just can not produce spark yet, does not have the effect of arc when having reached combined floodgate and separating brake.
