Abstract
The utility model discloses the indoor circuit breaker vacuum switch tube of a kind of 12kV, relate to a kind of 12kV vacuum switch tube.It comprises porcelain cylinder, moving conductive rod and static conductive rod is provided with at the two ends shaft core position of porcelain cylinder, there is moving contact the termination of moving conductive rod, there is fixed contact the termination of static conductive rod, fixed contact contacts with moving contact, be provided with protective cover between moving contact and moving conductive rod, fixed contact is fixed on one end of porcelain cylinder by quiet end cap; Be provided with bellows between described moved end lid and protective cover, bellows-sheathed is contained on moving conductive rod; Moving contact, fixed contact and static conductive rod are positioned at shielding cylinder, between described quiet end cap and porcelain cylinder and moved end is covered and is all sealed by grading ring between porcelain cylinder, the upper end of described moving conductive rod is set with flange and moved end lid successively, moved end lid is fixed on the other end of porcelain cylinder, be provided with external screw thread outside described flange, inside flange, be provided with internal thread.Because the utility model is fixed on indoor circuit breaker by flange, therefore turned by the utility model in the process being fitted on indoor circuit breaker, rocking not easily appears in the utility model.
Description
Technical field
The utility model relates to a kind of 12kV vacuum switch tube, specifically the indoor circuit breaker vacuum switch tube of a kind of 12kV.
Background technology
The upper end of the moving conductive rod of the indoor circuit breaker vacuum switch tube of existing 12kV is set with fairlead and moved end lid successively, when vacuum switch tube is assembled on indoor circuit breaker, the moved end of vacuum switch tube is fixed by the chuck on indoor circuit breaker, the indoor circuit breaker of the 12kV assembled by above-mentioned prior art is when folding, rocking easily appears in the body of vacuum switch tube, easily cause contact dystopy, and then cause vacuum tube probability of damage bigger than normal, increase production cost, be therefore necessary to improve.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and provides the indoor circuit breaker vacuum switch tube of a kind of 12kV.
To achieve these goals, the technical solution of the utility model is: the indoor circuit breaker vacuum switch tube of 12kV, comprise porcelain cylinder, moving conductive rod and static conductive rod is provided with at the two ends shaft core position of porcelain cylinder, there is moving contact the termination of moving conductive rod, and there is fixed contact the termination of static conductive rod, and fixed contact contacts with moving contact, be provided with protective cover between moving contact and moving conductive rod, fixed contact is fixed on one end of porcelain cylinder by quiet end cap; Be provided with bellows between described moved end lid and protective cover, bellows-sheathed is contained on moving conductive rod; Moving contact, fixed contact and static conductive rod are positioned at shielding cylinder, between described quiet end cap and porcelain cylinder and moved end is covered and is all sealed by grading ring between porcelain cylinder, it is characterized in that: the upper end of described moving conductive rod is set with flange and moved end lid successively, moved end lid is fixed on the other end of porcelain cylinder, be provided with external screw thread outside described flange, inside flange, be provided with internal thread.
The utility model structure is simple, easy to use, and the utility model changes the fairlead of existing vacuum switch tube into flange, and offer external screw thread outside flange, offers internal thread inside flange.During real work, because the utility model is fixed on indoor circuit breaker by flange, therefore turned by the utility model in the process being fitted on indoor circuit breaker, the utility model structure is more stable, and contact not easily dystopy occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-moving conductive rod in figure, 2-fixed contact, 3-moved end is covered, 4-porcelain cylinder, the quiet end cap of 5-, 6-static conductive rod, 7-flange, 8-bellows, 9-protective cover, 10-moving contact, 11-shielding cylinder, 12-grading ring.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model clearly and easy understand by explanation simultaneously.
Accompanying drawings is known: the indoor circuit breaker vacuum switch tube of 12kV, comprise porcelain cylinder 4, moving conductive rod 1 and static conductive rod 6 is provided with at the two ends shaft core position of porcelain cylinder 4, there is moving contact 10 termination of moving conductive rod 1, there is fixed contact 2 termination of static conductive rod 6, fixed contact 2 contacts with moving contact 10, is provided with protective cover 9 between moving contact 10 and moving conductive rod 1, and fixed contact 2 is fixed on one end of porcelain cylinder 4 by quiet end cap 5; Be provided with bellows 8 between described moved end lid 3 and protective cover 9, bellows 8 is sleeved on moving conductive rod 1; Moving contact 10, fixed contact 2 and static conductive rod 6 are positioned at shielding cylinder 11, between described quiet end cap 5 and porcelain cylinder 4 and moved end is covered between 3 and porcelain cylinder 4 and is all sealed by grading ring 12, it is characterized in that: the upper end of described moving conductive rod 1 is set with flange 7 and moved end lid 3 successively, moved end lid 3 is fixed on the other end of porcelain cylinder 4, be provided with external screw thread outside described flange 7, inside flange 7, be provided with internal thread.
In the closed procedure of vacuum circuit-breaker, moving conductive rod 11 carries out 9 ± 1mm extensional motion, thus fixed contact 8 and moving contact 9 can be made to close and separate.When the utility model is assembled on indoor circuit breaker, quiet end is fixed by static conductive rod 1 screw, moved end is fixed by screwed flange 7, therefore in moving conductive rod motion process, the vacuum switch tube be arranged on indoor circuit breaker not easily rocks, and strengthens the security performance of the utility model and indoor circuit breaker.
Other unaccounted part all belongs to prior art.
