Abstract
The utility model relates to a contact device of an isolating switch. The prior isolating switch has many potential hazards in a large-current circuit and cannot ensure long-time stable use. The contact device of the isolating switch comprises an isolating switch which is vertically fixed on a positioning column through a nut. The isolating switch is internally provided with a static contact. The contact device of the isolating switch is characterized in that: a first spring pressure board and a second spring pressure board are respectively arranged between the isolating switch and the nut; a pressure spring is arranged between the first spring pressure board and the nut; at the side of the static contact, the first spring pressure board and the second spring pressure board are respectively provided with a contact for acting on the isolating switch; and at the other side, the first spring pressure board is connected with the second spring pressure board through a pin. The contact device of the isolating switch can ensure long-time stable application of the isolating switch in the large-current circuit.
Description
Technical field
the utility model relates to isolating switch technical field, is specifically related to a kind of contact apparatus of isolating switch.
Background technology
Along with the steady rapid growth of economy, improving constantly of people's lives, annual power consumption and need for electricity also highlight day by day, west-to-east power transmission, remote conveying etc. are all the methods that solve electricity consumption difficulty, therefore each power equipment was also improved constantly to requirement in recent years, various electricity consumptions arrange capacity to be increased thereupon, in mesohigh electric power system, line current constantly promotes, and large electric current power supply is day by day universal.
Isolating switch system is a visual plant of electric power system, for locomotive provides electric energy power, direct relation the reliable power supply of locomotive, be a very important power supply unit.The structure of isolating switch mainly comprises at present: support underframe, insulating element and conductive component, in conductive component, be divided into again moving contact, fixed contact and isolation knife, fixed contact is positioned at isolation knife, in isolation knife, there is the contact of touching fixed contact, connected or disconnected by the action of isolation knife, dynamic and static contact is to realize energising or power down function; Isolating switch is the equipment of a frequent operation, and the electric conductivity of its long time stability is that locomotive power supply guarantees reliably, but existing isolating switch exists a lot of hidden danger in heavy current circuit, can not guarantee the use of isolating switch long-term stability.
Summary of the invention
The purpose of this utility model is to provide a kind of contact apparatus that is applied to the isolating switch in heavy current circuit that can make isolating switch long-term stability.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of contact apparatus of isolating switch, comprise isolation switch, described isolation switch is vertically fixed on reference column by nut, fixed contact is set in isolation switch, its special feature is: between described isolation switch and nut, be respectively arranged with the first spring bearer plate and the second spring bearer plate, between the first spring bearer plate and nut, be provided with stage clip; With the first spring bearer plate of fixed contact homonymy and the second spring bearer plate on be respectively arranged with the contact of effect isolation switch, the first spring bearer plate is connected by bearing pin with the opposite side of the second spring bearer plate.
Contact on described the first spring bearer plate and the second spring bearer plate is respectively 1.
Compared with prior art, the utlity model has following beneficial effect:
1. between stage clip and upper spring pressing plate, spring bearer plate is set, the pressure of spring is passed to isolation knife by spring bearer plate like this, directly acts on the contact position of stationary contact power and isolation knife, and isolation switch just can not be out of shape owing to being subject to for a long time spring pressure;
2. because isolation knife is not yielding, the pressure of contact can remain on reasonable level scope always, can guarantee like this use of isolating switch long-term stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. reference column; 2. isolation switch, 3. nut, 4. stage clip, 5. the first spring bearer plate, 6. the second spring bearer plate, 7. contact, 8. fixed contact, 9. bearing pin.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
Referring to Fig. 1, a kind of contact apparatus of isolating switch, comprise isolation switch 2, isolation switch 2 is vertically fixed on reference column 1 by nut 3, the interior fixed contact 8 that arranges of isolation switch 2, between isolation switch 2 and nut 3, be respectively arranged with between the first spring bearer plate 5 and the second spring bearer plate 6, the first spring bearer plates 5 and nut 3 and be provided with stage clip 4; With the first spring bearer plate 5 of fixed contact 8 homonymies and the second spring bearer plate 6 on be respectively arranged with the contact of effect isolation switch 2, the opposite side of the first spring bearer plate 5 and the second spring bearer plate 6 is connected by bearing pin 9.
Contact 7 on the first spring bearer plate 5 and the second spring bearer plate 6 is respectively 1.
Operation principle of the present utility model is: stage clip 4 is stressed, then by its force transmission to the first spring bearer plate 5, the first spring bearer plate 5 is passed to isolation switch 2 again with the contact jaw of isolation switch 2, isolation switch 2 directly acts on fixed contact 8, has so just avoided isolation switch 2 to be directly subject to stage clip 4 active forces and has been out of shape.
Claims (2)
1. the contact apparatus of an isolating switch, comprise isolation switch (2), described isolation switch (2) is vertically fixed on reference column (1) by nut (3), fixed contact (8) is set in isolation switch (2), it is characterized in that: between described isolation switch (2) and nut (3), be respectively arranged with the first spring bearer plate (5) and the second spring bearer plate (6), between the first spring bearer plate (5) and nut (3), be provided with stage clip (4); With first spring bearer plate (5) of fixed contact (8) homonymy and the second spring bearer plate (6) on be respectively arranged with the contact (7) of effect isolation switch (2), the opposite side of the first spring bearer plate (5) and the second spring bearer plate (6) is connected by bearing pin (9).
2. the contact apparatus of a kind of isolating switch according to claim 1, is characterized in that: the contact (7) on described the first spring bearer plate (5) and the second spring bearer plate (6) is respectively 1.
