Because the voltage transformer adopting the structure is formed by that the insulating contact arm is arranged on the periphery of the fuse, the safety performance of the handcart is enhanced.
Description
Technical field
The utility model relates to a kind of dedicated potential transformer handcart of high-tension switch cabinet, the voltage transformer handcart that particularly a kind of fuse is built-in.
Background technology
Existing high-tension switch cabinet dedicated potential transformer handcart generally is that fuse is directly exposed to the handcart outside, its structure is that voltage transformer is fixed on the cart frame, by insulation column, connection row contact arm and cluster contact are fixed on required horizontal level, be connected row by many and spring clip is fixed on fuse in the framework between contact arm and voltage transformer, mechanism realizes the propelling of handcart and shakes out by shaking into then.This voltage transformer handcart has increased danger coefficient because the direct exposure of fuse has caused the reduction of insulation property, and moving contact has adopted plug-type strap-on structure, has increased handcart and has cooperated the difficulty of debugging with cabinet.
Summary of the invention
Task of the present utility model is to solve the above-mentioned problems in the prior art, provides a kind of fuse built-in voltage transformer handcart.
Its technical solution is:
The voltage transformer handcart that a kind of fuse is built-in comprises and shakes into mechanism, installation frame, voltage transformer, insulation column and fuse that the end of described insulation column is provided with the insulation contact arm of hollow, and fuse is arranged in insulation contact arm inner chamber.Adopt the voltage transformer handcart of this structure owing to be provided with the insulation contact arm, so improved the security performance of handcart in the periphery of fuse.
Be provided with conducting terminal in the above-mentioned insulation contact arm inner chamber, conducting terminal is electrically connected with fuse, and conducting terminal is electrically connected fuse by lead with voltage transformer.
Have connecting hole on the chamber wall of above-mentioned insulation contact arm, the cardinal extremity that above-mentioned conducting terminal is positioned at the insulation contact arm links by lead and the voltage transformer that passes connecting hole.
Also be provided with spring in the inner chamber of above-mentioned insulation contact arm, an end and the fuse of spring link, and the cardinal extremity of the other end and insulation contact arm links and keeps in touch with conducting terminal.
The contact end of above-mentioned insulation contact arm is provided with can be along the moving contact of insulation contact arm inner chamber slip.
The cardinal extremity of above-mentioned moving contact is provided with projection, is arranged in the insulation contact arm inner chamber, and free end reveals to be put outside the insulation contact arm.The projecting end and the fuse of above-mentioned moving contact keep in touch, free end is used for contacting with the cabinet fixed contact, utilize the elastic force of spring that moving contact is slided in insulation contact arm inner chamber, so that better contact with fixed contact in the cabinet, thereby significantly reduced the difficulty of handcart and cabinet debugging, improved efficiency of assembling.
The contact end of above-mentioned insulation contact arm is furnished with the thread bush that is nested with on the moving contact free end, and above-mentioned thread bush is threaded with the contact end of insulation contact arm.Adopt this structure, the cardinal extremity of moving contact can be limited between thread bush and the fuse, make the certain contact pressure of maintenance between moving contact and the fuse, can prevent that also the elastic force of spring from ejecting insulation contact arm inner chamber with moving contact.
