Abstract
The present utility model relates to a secondary wire leading-out device of a hermetic sealing air chamber, especially to a secondary wire leading-out device of gas insulation switch equipment of an electric power system. The device comprises a hermetic sealing fixing pedestal and a hermetic sealing cover arranged on an air chamber shell, wherein a bayonet of the hermetic sealing cover is arranged on the hermetic sealing fixing pedestal; and a secondary wire pin and an insulation plug connected with a secondary wire, the secondary wire pin passes through and is fixed on the hermetic sealing fixing pedestal, and the insulation plug is fitted and connected with the secondary wire pin in a plugging way. The plugging is convenient, and hermetic sealing performance of the leading-out device can be enhanced.
Description
Technical field
The utility model relates to a kind of secondary line ejector of sealed air chamber, especially, and the secondary line ejector in the electric power system on the gas-insulated switchgear.
Background technology
In electric power system; The secondary line ejector (aviation plug) that relates to a kind of sealed air chamber; It mainly acts on is that secondary line with in the air chamber is drawn, and the secondary line ejector of existing sealed air chamber is that the mode through direct welding is connected with secondary line basically, and is not enough below this connected mode exists: the one, and the secondary line ejector volume of conventional sealed air chamber is big; Especially height dimension is big, and the volume that takes up space is big; The 2nd, the secondary line ejector of conventional sealed air chamber can not be realized hermetic seal, has satisfied not the requirement of function when high for the air chamber sealing requirements; The 3rd, the secondary line ejector secondary line of conventional sealed air chamber is installed and is all adopted the welding fixed form; Not only the secondary line technique for fixing is complicated; Workman's technical ability is required high, and if occur secondary line in the equipment operation and come off, often face difficult in short-term predicament of replying; The 4th, the secondary line ejector of conventional sealed air chamber receives the influence of condensation easily because the syringe needle root exposes, and causes the secondary line risk of short-circuits.
The utility model content
The technical problem that the utility model solves is, a kind of secondary line ejector of easy to connect, the simple in structure and sealed air chamber that coefficient of safety is high is provided.
In order to solve the problems of the technologies described above; The technical scheme that the utility model provides is that a kind of secondary line ejector of sealed air chamber comprises: be installed in sealing and fixing seat and seal cover on the air chamber shell; The seal cover bayonet socket is on the sealing and fixing seat; Also comprise secondary line contact pin and the blind plug that is connected secondary line, the secondary line contact pin runs through and is fixed on the sealing and fixing seat, and blind plug and secondary line contact pin plug-in are connected;
Improvement project also comprises the O RunddichtringO, and it is embedded on the contact-making surface of the gentle chamber enclosure of sealing and fixing seat;
Improvement project, the root of secondary line contact pin covers insulating barrier;
Preferred version, sealing and fixing seat also comprise it are installed in the set bolt on the air chamber shell.
Compare with prior art, the beneficial effect that the utility model produces is that the blind plug and the secondary line contact pin plug-in that connect secondary line are connected, and secondary line can be installed or pull down with the secondary line contact pin as required, and be easy to operate; The O RunddichtringO is set, has improved the sealing effectiveness of sealed air chamber; Secondary line contact pin root covers insulating barrier, stops condensation and causes short circuit; Adopt plug-in to connect the height of the secondary line ejector that can effectively shorten sealed air chamber.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In the accompanying drawing, 1. air chamber shell; 2.O RunddichtringO; 3. sealing and fixing seat; 4. secondary line blind plug; 5. seal cover; 6. secondary line; 7. set bolt; 8. secondary line contact pin.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
In prior art; The secondary line ejector of sealed air chamber need be connected with secondary line through welding manner, so just produces above-mentioned technical problem, in order to make improvements; Need welding manner be changed into other connected modes; On the basis of this design, the utility model provides a kind of plug-in connected mode, has effectively solved the deficiency that exists in the prior art.
Specifically be that the secondary line ejector of sealed air chamber comprises: be fixed on the sealing and fixing seat 3 on the air chamber shell 1; And the seal cover 5 of bayonet socket on sealing and fixing seat 3, be fixed with secondary line contact pin 8 in order to realize being connected, to run through on the sealing and fixing seat 3 with secondary line 6; Secondary line contact pin 8 is moderate in the extension elongation on sealing and fixing seat 3 two sides, and is unsuitable oversize, also comprises the blind plug 4 that is connected with secondary line 6; Secondary line 6 is through the mode of extruding, is connected an end of insulation 4, and the other end of blind plug 4 and secondary line contact pin 8 are connected through pluggable mode; Not only saved complicated welding procedure, and operation is very convenient, if local damage; Can in time change, thereby raise the efficiency economical with materials, blind plug 4 has insulation crust; Be inserted on the secondary line contact pin 8, can also play insulating effect, avoid producing harm such as short circuit.
Further improve, can be on sealing and fixing seat 3 gentle chamber enclosure 1 contact-making surfaces an O type of setting-in sealing ring 2, its material can be selected rubber etc., like this, has improved the air-tightness of sealed air chamber; In addition, the root of secondary line contact pin 8 can also cover a layer insulating, effectively like this stops condensation and causes risk of short-circuits; Sealing and fixing seat 3 is preferably fixed through complete set bolt 7 gentle chamber enclosures 1, and fixed effect is good.
Claims (4)
1. the secondary line ejector of a sealed air chamber; Comprise: be installed in sealing and fixing seat and seal cover on the air chamber shell; The seal cover bayonet socket is characterized in that on the sealing and fixing seat, also comprises secondary line contact pin and the blind plug that is connected secondary line; The secondary contact pin runs through and is fixed on the sealing and fixing seat, and blind plug and secondary line contact pin plug-in are connected.
2. according to the secondary line ejector of the said sealed air chamber of claim 1, it is characterized in that also comprise the O RunddichtringO, it is embedded on the contact-making surface of the gentle chamber enclosure of sealing and fixing seat.
