Abstract

The utility model discloses a three-station isolation switch insulation pull rod. The three-station isolation switch insulation pull rod comprises an insulator and a connection rod, wherein one end of the insulator is provided with an embedding member, the embedding member is provided with a first spring and a second spring, the connection rod is further provided with an annular convex flange separating the first spring from the second spring, a port portion of the embedding member is provided with a sealing nut, the connection rod penetrates through the sealing nut, the connection rod is in sliding matching with the embedding member and the sealing nut, one end of the first spring presses against a bottom portion of the embedding member, the other end of the first spring presses against the annular convex flange, one end of the second spring presses against the annular convex flange, and the other end of the second spring presses against the sealing nut. According to the three-station isolation switch insulation pull rod, the two springs provide contact pressure force of moving and static contacts of a three-station isolation switch, and the rotating sealing nut can realize pressure adjustment of the two springs; in a production process, pressure magnitudes of the springs can be directly realized through assembling and debugging on a spring testing instrument, the pressure magnitudes can be controlled, a production standardization degree is high, adjusting workload is small, and production cost is low.

Description

Tri-station isolating switch insulated tension pole
Technical field
The utility model relates to a kind of high voltage switch part, particularly a kind of tri-station isolating switch insulated tension pole.
Background technology
Tri-station isolating switch generally adopts disconnecting link formula at present, and its conducting surface contact provides with the spring that is directly pressed in blade both sides, and insulated tension pole does not provide contact pressure.This makes isolation switch contact contact entirely with artificial random adjustment, contact size is uncontrollable, and then makes tri-station isolating switch quality unstable, and standardization level is low, and in production process, the adjustment workload of tri-station isolating switch is large, and production cost is higher.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of tri-station isolating switch insulated tension pole, uncontrollable to solve existing tri-station isolating switch contact pressure, adjusts workload large, the problem that production cost is high.
The utility model insulated tension pole, comprises insulator and connecting rod, and one end of described insulator is provided with inserts, is provided with the first spring and the second spring in described inserts, and two springs adopt spring of the same race;
Described connecting rod is inserted in the first spring and the second spring, is also provided with the first spring and the separated annular flange flange of the second spring on connecting rod, leaves the compression travel space of spring between connecting rod and inserts bottom; The oral area of described inserts is provided with blind nut, and described connecting rod is through blind nut, and described connecting rod and inserts and blind nut are slidably matched;
One end of described the first spring withstands on inserts bottom, the other end withstands in annular flange flange, and one end of described the second spring withstands in annular flange flange, and the other end withstands on blind nut.
The beneficial effects of the utility model: the utility model insulated tension pole, its connecting rod is for being connected with the moving contact of tri-station isolating switch, in tri-station isolating switch, the dynamic and static contact pressure of combined floodgate station is provided by the first spring, the dynamic and static contact pressure of ground connection station is provided by the second spring, and rotary seal nut can be adjusted spring pressure; In process of production, the pressure equal and opposite in direction of two springs in this insulated tension pole, can be directly on spring dynamometer assembling and setting complete, its power value size is controlled, the production standard degree of insulated tension pole is high, and spring force value adjustment workload is less, and production cost is low.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model insulated tension pole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment insulated tension pole, comprises insulator 1 and connecting rod 2, and one end of described insulator 1 is provided with inserts, is provided with the first spring 3 and the second spring 4 in described inserts;
Described connecting rod 2 is inserted in the first spring 3 and the second spring 4, is also provided with the first spring 3 and the separated annular flange flange 5 of the second spring 4 on connecting rod, leaves the compression travel space of the first spring 3 between connecting rod 2 and inserts bottom; The oral area of described inserts is provided with blind nut 6, and described connecting rod 2 is through blind nut, and described connecting rod 2 is slidably matched with inserts and blind nut 6;
One end of described the first spring 3 withstands on inserts bottom, the other end withstands in annular flange flange 5, and one end of described the second spring 4 withstands in annular flange flange 5, and the other end withstands on blind nut 6.
The present embodiment insulated tension pole, under confined state, the moving contact of its connecting rod 2 and tri-station isolating switch is connected, and the other end of insulator 1 is connected with the operating mechanism of tri-station isolating switch.The dynamic and static contact pressure of dynamic and static contact pressure of the combined floodgate station of tri-station isolating switch is provided by the first spring 3, the dynamic and static contact pressure of ground connection station is provided by the second spring 4, and rotary seal nut 6 can be adjusted the pressure of the first spring 3 and the second spring 4; In process of production, the large I of pressure of two springs in this insulated tension pole directly on spring dynamometer assembling and setting complete, its power value size is controlled, the production standard degree of insulated tension pole is high, and spring force value adjust workload less, production cost is low.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
