Abstract
The utility model relates to a rotatable contact holding spring for a high-voltage vacuum switch, belonging to a matching component in the technical field of high-voltage switches. The utility model is mainly composed of a spring seat 4, a spring guide bar 1 and a spring 3 which are arranged in the spring seat, thrust bearings 5 arranged on two ends of the spring, prepressing nuts 2 arranged on the upper part of the spring seat, etc. The utility model can be used for causing the spring guide bar to move up and down and providing stable contact pressure for a movable and a static contacts of the high-voltage vacuum switch, and the spring guide bar can also rotate freely and horizontally to open and close an isolating switch, and the integral structure of the high-voltage vacuum switch tends to be compact and reasonable.
Description
The utility model relates to the structural design that a kind of high-pressure vacuum switch rotary type contact keeps spring, belongs to the matching component of high-voltage switch gear technical field.
Contact keeps the effect of spring to provide the stable contact pressure of the dynamic and static contact of high-pressure vacuum switch, prevent contact bounce, melting welding, on vacuum switch, be widely used, but needs along with vacuum switch and isolating switch combination, keep-uping pressure when common contact keeps spring can only provide the dynamic and static contact of vacuum switch to contact is so be difficult to adapt to user's needs under the trend of switch miniaturization.
The purpose of this utility model provides a kind of reasonable in design, the contact pressure of the dynamic and static contact of high-pressure vacuum switch both can be provided, again can be by the rotation of spring conductor rod, the high-pressure vacuum switch rotary type contact that makes isolating switch can carry out branch, closing operation smoothly keeps spring.
The utility model is that high-pressure vacuum switch rotary type contact keeps spring, comprise spring base, place spring conductor rod and spring in the spring base, spring conductor rod passes spring, stretch out outside the spring base on its top, it is characterized in that also comprising simultaneously the thrust bearing that places both ends of the spring.Described spring base top also can be provided with the precompressed nut, is convenient to the installation of spring and spring conductor rod.
The utility model reasonable in design, spring conductor rod both can move up and down, and stable contact pressure is provided when contacting for the dynamic and static contact of high-pressure vacuum switch; Owing to be provided with two thrust bearings in the spring base, spring conductor rod can freely horizontally rotate again, makes isolating switch can carry out branch, closing operation freely simultaneously.
Accompanying drawing has provided structural representation of the present utility model:
Fig. 1 is an overall structure cutaway view of the present utility model.
Fig. 2 is used for structure cutaway view on the high-pressure vacuum switch for the utility model.
Below in conjunction with embodiment the utility model is further described:
The utility model is mainly by spring base 4, place spring conductor rod 1 and spring 3 in the spring base, place two thrust bearings 5 at spring 3 two ends, place precompressed nut 2 formations such as grade on spring base top, spring conductor rod 1 passes spring 3 in spring base 4, its top is stretched out spring base 4 and is linked to each other with last seven word connecting levers 7, and the bottom of spring base 4 can link to each other with the insulated tension pole 6 of switch operating mechanism.
When switch closes a floodgate, switch operating mechanism pulling insulated tension pole 6, insulated tension pole 6 moves downward together with spring base 4, and spring conductor rod 1 is subjected to the restriction of seven word connecting levers 7 to make spring 3 compressions, stable contact pressure is provided for the dynamic and static contact contact of high-pressure vacuum switch.
During the plug-in strip operation, the rotation of plug-in strip operating mechanism drive three-phase operation waling stripe, waling stripe makes supports insulation letter and spring conductor rod 1 rotation, and the dynamic and static contact of plug-in strip is separated, and realizes separating brake.
Claims (2)
1, a kind of high-pressure vacuum switch rotary type contact keeps spring, comprise spring base (4), place spring conductor rod (1) and spring (3) in the spring base, spring conductor rod passes spring, stretch out outside the spring base on its top, it is characterized in that also comprising simultaneously the thrust bearing (5) that places both ends of the spring.
2, keep spring by the described high-pressure vacuum switch rotary type of claim 1 contact, it is characterized in that described spring base (4) top also can be provided with the precompressed nut.
