Abstract
The utility model relates to a bus type current transformer high voltage shielding net connection structure comprising a casting body and a shielding net installed on the casting body. The bus type current transformer high voltage shielding net connection structure is characterized in that the shielding net is connected with inserts through conductors, the inserts are installed on the casting body, and the inserts are provided with connectors exposed to out of the casting body. The bus type current transformer high voltage shielding net connection structure has the advantages of being simple in structure, easy to manufacture, reliable in connection, and good in shielding effect.
Description
Technical field
The utility model belongs to the instrument transformer technical field, particularly relates to a kind of high-tension shielding structure of bus type mutual inductor.
Background technology
The high-tension shielding net is the vitals of electrical network median generatrix formula instrument transformer, the high-tension shielding net generally is inlaid in the pour mass inside of instrument transformer, gauze screen need to be connected with high-tension cable or the copper bar line of pour mass outside, plays the functions such as burr and the some position of suspending of screaming of balanced high voltage electric field, shielding high potential.The high-tension shielding structure of tradition bus type mutual inductor is: the high-tension shielding net mould inside of packing into, after cast, the high-tension shielding net is close to the pour mass inwall, brushes semiconductor varnish on the pour mass inwall, and the copper rod in cable or copper bar line contacts with semiconductor varnish, realize and being connected of high-tension shielding net with this, the shortcoming that this structure exists is: structure is installed and is formed complex procedures, and semiconductor varnish and copper rod are difficult to guarantee closely, cause loose contact, shielding was lost efficacy, and formed floating potential.
Summary of the invention
The utility model for solve the technical problem that exists in known technology provide a kind of simple in structure, make simple, as to connect the bus type mutual inductor reliable, that shield effectiveness is good high-tension shielding structure.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of bus-type current transformer high-tension shielding net syndeton, comprise pour mass and the gauze screen that is arranged on pour mass, described gauze screen is by the conductor connection inserting part, described inserts is arranged on described pour mass, has the interface that exposes described pour mass on described inserts.
The utility model can also adopt following technical scheme:
Described conductor is soft plain conductor.
Interface on described inserts is hickey.
It is inner that described gauze screen is inlaid in described pour mass.
The utility model is compared advantage and the good effect that conventional art has:
1. the utility model comprises inserts, and inserts connects gauze screen by conductor, and in the dress mold process, inserts pack in mould relevant position and use bolted, gauze screen to be inserted in the mould axle fills mold process simple, and more time saving and energy saving.
2. inserts can reliably be connected by outreaching contact pin with high-tension cable or the copper bar line of pour mass outside, avoids the gauze screen loose contact, effectively improves the shield effectiveness of current transformer, has solved the floating potential problem, makes mutual inductance general ability flat raising that discharge water.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, pour mass; 2, gauze screen; 3, inserts; 4, plain conductor.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of bus-type current transformer high-tension shielding net syndeton, comprise pour mass 1 and gauze screen 2, gauze screen 2 is arranged on pour mass 1, gauze screen 2 is by conductor connection inserting part 3, inserts 3 is arranged on pour mass 1, has the interface that is connected for the high-voltage conducting wires of pour mass 1 outside or copper bar line etc. on inserts 3, and the interface of inserts 3 exposes the surface of pour mass 1.In the dress mold process, pack in mould relevant position and use bolted of inserts 3, gauze screen 2 is inserted in the axle of mould, after casting complete, the interface of inserts 3 exposes pour mass 1 surface, is convenient to the high-voltage conducting wires of gauze screen 2 and pour mass 1 outside or copper bar line etc. with this and is connected.
In the present embodiment, gauze screen 2 is inlaid in pour mass 1 inside, and the interface on inserts 3 is hickey, and inserts 3 can be connected with the outer brace of high-voltage conducting wires by hickey.Inserts 3 is connected by soft plain conductor 4 with gauze screen 2.
Above-mentioned execution mode is only to functional descriptions of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model are within all dropping on protection range of the present utility model.
Claims (4)
