Abstract
The current path in the quenching chamber, with a closed position of the contacts is arranged parallel to the double isolating blade, and a switch shaft (10) is provided for the operation of the switch. The fixed contact (2) is secured on a carrying plate (3), which by means of a spring (5) contacts a pin (6), which is electrically connected with the double isolating blade (7). The fixed contact (2) is pressed and sintered from tungsten powder and is backed with fluid copper on the carrying plate (3). The double isolating blade (7) can additionally be brought into contact to a connection contact (15) using a contact part (9), which is arranged parallel to the moving contact (4) of the quenching chamber (1) and an impact contact (8). A perforated plate (11) with an inner bushing (12) is mounted on the switch shaft (10). The bushing (12) is made of synthetic material. USE/ADVANTAGE - Tilting tube load breaking isolating switch of old type developed and improved, so that number of possible current breaking operations, short circuit strength and contact making ability is increased.
Description
The present invention relates to a kind of load isolating switch for inclined pipe.
Such load isolating switch for inclined pipe is known (seeing DEPS2353627), and what relate to here is a kind of switch that is always using in recent decades.Because the new demand that the international market proposes must be done further improvement to some the important particulars or the parts of this switch.
Task of the present invention is, a kind of load isolating switch for inclined pipe of mentioned kind is provided, the number that opens circuit that it is possible, and anti-short circuit capability and making capability all are improved.
The present invention has pointed out for people how one make prior art continue to access the approach of utilization by some improvement.For example the fixed contact of quenching pot (chamber) is made by tungsten powder extruding sintering, and at the liquid copper of supporting plate top casting as substrate.Two separation plug-in strips are furnished with and are parallel to the contact part that connects contact, are twice thereby contact area is increased, and in addition, an orifice plate (index dial) are housed on switch shaft, are lined with a measure such as axle sleeve in the orifice plate.
This load isolating switch for inclined pipe can be used in all medium voltage switchgear equipments, and for example those must be according to the switchgear of ANSI rules manufacturing.
The peeling off or split of contact material when advantage of the present invention especially has been to avoid to connect prolonged the life-span of switch part so widely, and this also helps to make the wearing and tearing of switch few.In order to satisfy higher short circuit requirement, it is effective increasing with two effects that separate the contact-making surface of plug-in strip.In order to compensate additional contact friction (this friction is harmful to the reliable location of quenching pot), an axle sleeve of being made by synthetic material is set on switch shaft, can play good effect.
Below the embodiments of the invention shown in the accompanying drawing are described in detail.
The part of a quenching pot of Fig. 1 is cutd open end view;
End view when the part of Fig. 2 quenching pot is in and engages with embedded contact;
Fig. 3 to Fig. 5 contacts three different views of part;
One of Fig. 6 belongs to the end view of the switch shaft that axle sleeve and orifice plate (index dial) are housed of load-break switch;
Two views of Fig. 7 and Fig. 8 load isolating switch for inclined pipe.
According to Fig. 1, in a tubular quenching pot 1, a fixed contact 2 is fixed on the supporting plate 3.Here, solid contact 2 is made by tungsten powder extruding and sintering, and on supporting plate 3 with liquid copper casting.Movable contact 4 is designed to spherical head, and this head is fixed on the switch lever 19.Contact tube 20 surrounds switch lever 19, this switch lever 19 and self-cleaning contact 21 terminations.Fixed contact 2 is linked to each other with a spring 5 by its supporting plate 3, and this spring 5 forms by bolt 6 sees Fig. 7 and Fig. 8 with two plug-in strip 7(that separate) electrical connection.
In Fig. 2, movable contact 4 is inserted in the embedded contact in top of load isolating switch for inclined pipe.Contact part 9 is used to increase and two contact-making surfaces that separate plug-in strip, two separation plug-in strips be connected contact 15 and engage, and be attached to the contact part (9) that is connected on the contact (15) and engage.Contact area is doubled.Contact part 9 and be connected contact 15(and see Fig. 7) be fixed on together on the bearing insulation on 16, contact part 9 and be connected contact 15 and spin by screw together.Contact part 9 is provided with abreast with the movable contact 4 and the embedding contact 8 of quenching pot 1.
According to Fig. 3 to Fig. 5, contact part 9 is made of a drip molding with two holes 13, and this drip molding has two extensions 14.Two extensions are to be provided with like this, and promptly towards its underpart direction, extension is tapered, and in other words, from the outside, towards the position that links to each other with drip molding, the distance between two extensions reduces gradually.In addition, two extensions and drip molding at right angles are provided with.
According to Fig. 6, an orifice plate (index dial) 11 is housed on the switch shaft 10, an axle sleeve 12 of being manufactured by synthetic material (for example Delrin) is housed in the orifice plate 11.Label 18 is a transmission levers.Switch shaft 10 is used to handle this load isolating switch for inclined pipe by means of switch lever 17.
Fig. 7 and Fig. 8 show three a complete utmost point load isolating switch for inclined pipe.
The current path of quenching pot is provided with two plug-in strips that separate under closed state with paralleling.
