Description
Technical field
The present invention relates to the electronic control technology field, particularly relate to a kind of dynamo-electric isolating construction for isolating switch support rotating place.
Background technology
The conductive arm support rotating place of tradition vertical cut-off type isolating switch, for guaranteeing reliable contact, the left and right sides conductive plate of conductive arm is clipped on the vertical part of quiet binding post tightly.When the switch divide-shut brake, the contact portion of the vertical part of left and right sides conductive plate and quiet binding post is forced rotating under larger clamping force, and frictional resistance is very large, contact portion serious wear, very easily heating.And behind divide-shut brake repeatedly, the contact portion wear down, the energising cross section is inadequate, easier heating, even sintering.Action required power is large simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of dynamo-electric isolating construction for isolating switch support rotating place, can reduce the workload of plant maintenance, and prolong useful life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of dynamo-electric isolating construction for isolating switch support rotating place is provided, comprise: left binding post, right binding post and conductive arm, be provided with conductive strips on the described left binding post, be provided with contact on the described right binding post, one end of described conductive arm is connected on the left binding post, and described left binding post is connected with right binding post by conductive arm.
In a preferred embodiment of the present invention, can be connected with right binding post smoothly for making conductive arm, described conductive arm middle part is provided with an insulated tension pole.
In a preferred embodiment of the present invention, for preventing the circuit board electric leakage, be respectively arranged with post insulator on described left binding post and the right binding post
The invention has the beneficial effects as follows: the present invention has added conductive strips between conductive arm and terminal board, and energising is by conductive strips, and the machine driving place need not conduct electricity, and has namely realized dynamo-electric separation.At first, become the original connection of living and transfer dead connection to, improved the reliability of energising; Secondly, electronic place need not clamping force, has completely abolished frictional damping, is difficult for heating, and rotates flexibly, has reduced operating physical force; Owing to without relatively friction, also just do not had the abrasion of material, prolonged the useful life of product simultaneously.Be specially adapted on the large product of rated current, the good results are evident.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises: a kind of dynamo-electric isolating construction for isolating switch support rotating place, comprise: left binding post 1, right binding post 2 and conductive arm 3, be provided with conductive strips 10 on the left binding post 1, be provided with contact 20 on the right binding post 2, one end of conductive arm 3 is connected on the left binding post 1, and left binding post 1 is connected with right binding post 2 by conductive arm 3.
Furtherly, described conductive arm 3 middle parts are provided with an insulated tension pole 30, and pulling insulated tension pole 30 can drive conductive arm 3 and rotate; Be respectively arranged with post insulator 4 on left binding post 1 and the right binding post 2.
The working method that the present invention is used for the dynamo-electric isolating construction at isolating switch support rotating place is: operation insulated tension pole 30, insulated tension pole 30 is pulled down, one end of conductive arm 3 turns clockwise centered by left binding post 1 thereupon, then the other end of conductive arm 3 drops on the contact 20 of right binding post 2, and simultaneously conductive strips 10 are deformed into ellipse by circle; The left binding post 1 of conductive strips 10 UNICOMs, conductive arm 3 and right binding post 2, electric current flows to conductive strips 10 and then flows to conductive arm 3 from left binding post 1, flow at last right binding post 2, whole galvanization mechanical driving part does not participate in conduction, and the fixed axis junction that mechanical part is conductive arm one end does not participate in conduction.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
