Abstract
The present invention is " the open-air anti-theft device for transformer of fastening-type ".Prevent that the seasonal field electric transformer core body that uses is stolen and design.By forming at anti-saw packing ring, saw preventing sleeve tube, the tang tubular-shank rivet of HRC56-62 through Carburization Treatment hardness.After this device is installed, can make the offender to transformer with spanner tear open not open, motionless with saw saw, do not bore with hand drill, really play antitheft effect.During maintenance only with hand drill a little reaming just can pull down, and reusable.
Description
Along with the development of State Grid's cause, vast rural power facility is gradually improved, but also corresponding the increasing of transformer core body theft case part.Some lawless persons utilize the machine of power failure in slack season, and the transformer loam cake is unloaded or cuts with the screw that connects between the casing, and its core body is stolen.For guaranteeing that national wealth do not suffer a loss, the spy has invented " fastening-type theft-proof device for transformers ".
This device is by a tang tubular-shank rivet 1; Two taper faced washers 2,10; A saw preventing sleeve tube 5; Three dismounting packing rings 3,8,9 are formed.Remove tang tubular-shank rivet 1, all the other parts 2,10; 3,8,9; 5 all adopt carburization process, and its surface hardness is HRC56-62, saw not open with hacksaw with realization.As shown in drawings, transformer loam cake 4, transformer seal rubber pad 6, transformer-cabinet 7 are riveted together during installation, tear open not open with spanner with realization with said apparatus.
When transformer carries out repair demolition, only need to limit the hexagonal end of tubular-shank rivet 1 with spanner, reaming is just removable a little with hand drill in riveted joint end hollow part.When installing again, only need to remove a dismounting packing ring 3,8 or 9 and can install again, thereby realize reusing.
The external diameter of tang tubular-shank rivet is 12MM, and as dismantling with general speed change hand drill reaming, its moment does not reach the requirement of required moment and can not dismantle.As carrying out reaming,, more can not dismantle because its space is subjected to the restriction of transformer tank wall with straight fast hand drill.
Every transformer covers thereon with casing and connects on the screw position, and four of well-balanced installations " fastening-type theft-proof device for transformers " just can possess the anti-theft feature of tearing open not open, sawing not open, tear open not open with hand drill with hacksaw with spanner.
