Abstract
A high voltage breaker vacuum spark quenching chamber contact static pressure device is provided, which is characterized by an insulation pull rod, with a bolt protruded from the top for connecting with the vacuum spark quenching chamber, and the bottom protruded with the rod body for connecting with a lifting lever, the rod body is inserted with a casing pipe, and a pressure spring, a spring holder and hinge pieces are arranged outside the casing pipe, the end of the rod body is arranged with thread and associated with locking nuts. Compared with the existing contact static pressure device, the utility model has stable static pressure that can be adjusted in advance, no trip-out problems during the HV breaker closed; the utility model has the advantages of compact structure, easy operation, convenient maintenance, and widely application, etc.
Description
Affiliated technical field
The utility model relates to high voltage power distribution and send the parts of electric equipment, specifically refers to a kind of static pressure device of primary cut-out vacuum arc-extinguishing chamber contact.
Background technology
The present domestic primary cut-out that is widely used in, the indoor contact of its vacuum extinction is a Mechanical Contact formula contact, when it is in contact condition, need a kind of static pressure that adds and make it keep the excellent contact state, and this static pressure generally is to be realized by the outdoor static pressure device of vacuum extinction.Present static pressure device mainly contains two kinds of versions, and a kind of is the contact static pressure device that adopts straightening mechanism, and there is huge, the heavy shortcoming of version in this device; Another kind is the contact static pressure device that adopts the butterfly spring structure, though this device has overcome huge, the heavy defective of version that aforesaid employing straightening mechanism exists, have compact conformation, flexible operation, easy characteristics, but because easy deformation behind the butterfly spring pressurized, the static pressure that produces easily changes, bounce can be produced during combined floodgate, normalizing operation and instructions for use can not be satisfied.
Summary of the invention
For the version that the static pressure contact apparatus that overcomes existing straightening mechanism exists huge, heavy, and the contact static pressure device of butterfly spring stressed yielding, static pressure easily changes, can produce problems such as spring when closing a floodgate, the utility model provides a kind of contact static pressure device of improved primary cut-out vacuum interrupter, can overcome the defective of prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of primary cut-out vacuum arc-extinguishing chamber contact static pressure device, it is characterized in that: an insulated tension pole, its top is extended and is used the screw rod that is connected with vacuum interrupter, extend bottom it and use the body of rod that is connected with lifting lever, a sheathed sleeve pipe on the described body of rod, sleeve pipe is arranged with compression spring, spring base and hinge spare outward, and described body of rod end is provided with screw thread, and is furnished with lock nut.
Good effect of the present utility model is: owing to adopted the contact static pressure device of compression spring version, it is stable that this device has static pressure, and use does not need debugging, and its static pressure can be adjusted in advance according to its Structural Design Requirement; Because static pressure is stable, so primary cut-out does not produce spring when closing a floodgate; The utility model is compared with existing contact static pressure device also has plurality of advantages such as compact conformation, flexible operation is easy, easy to maintenance, applicability is wide.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical profile schematic diagram of a kind of embodiment of the utility model.
Among the figure: 1, insulated tension pole; 2, screw rod; 3, the body of rod; 4, sleeve pipe; 5, compression spring; 6, top spring base; 7, bottom spring seat; 8, hinged component; 9, screw thread; 10, lock nut; 11, interior alcove.
Embodiment
With reference to Fig. 1, this primary cut-out vacuum arc-extinguishing chamber contact static pressure device, it is characterized in that: the insulated tension pole of a resin material (1), its top is extended and is used the screw rod (2) that is connected with vacuum interrupter, extend bottom it and use the body of rod (3) that is connected with lifting lever, the described body of rod (3) is gone up a sheathed sleeve pipe (4), outer compression spring (5), spring base (6) (7) and the hinged component (8) of being arranged with of sleeve pipe (4), the described body of rod (3) end is provided with screw thread (9), and is furnished with lock nut (10).In addition, spring base is made of top spring base (6) and bottom spring seat (7); Alcove (11) in one is arranged at insulated tension pole (1) bottom, and the body of rod (3) extends from interior alcove (11) bottom surface, and top spring base (6) is in the interior alcove (11), and the integral rigidity of static pressure device is better like this; The body of rod (3) is to be connected with lifting lever by the hinged component on it (8).
During use, the screw rod of static pressure device (2) is connected the vacuum interrupter bottom, and the hinged component (8) on the body of rod (3) is connected with lifting lever.When lifting lever was in upper position-arresting and puts, the static pressure device just produced the static pressure of setting to vacuum interrupter, made the indoor contact of vacuum extinction keep the excellent contact state.
Claims (4)
1, a kind of primary cut-out vacuum arc-extinguishing chamber contact static pressure device, it is characterized in that: an insulated tension pole, its top is extended and is used the screw rod that is connected with vacuum interrupter, extend bottom it and use the body of rod that is connected with lifting lever, a sheathed sleeve pipe on the described body of rod, sleeve pipe is arranged with compression spring, spring base and hinged component outward, and described body of rod end is provided with screw thread, and is furnished with lock nut.
2, by the described static pressure device of claim 1, it is characterized in that described spring base is made of top spring base and bottom spring seat.
3, by claim 1 or 2 described static pressure devices, it is characterized in that alcove in is arranged at described insulated tension pole bottom, the body of rod extends from interior alcove bottom surface, and it is indoor that the top spring base is in indent.
