Description
Technical field
The present invention relates to a kind of shielding line ground structure, more particularly to a kind of screen for impregnated dry-type transformer coil
Cover line ground structure.
Background technology
Dry-type transformer is cooled down by cross-ventilation, is generally used for the change such as local lighting, electronic circuit, plant equipment
In depressor, current dry-type transformer mainly has impregnated and two big type of epoxy resin formula, wherein impregnated dry-type transformer
The advantages of be that production cost is low without casting equipment and mould, the flexibility of product design is also larger.
In the production of reality, to increase the compressive resistance between the primary and secondary coil of dry-type transformer, at the beginning of avoiding or reducing,
Electric capacity electric discharge interference between secondary coil, can design placement screen layer between primary and secondary coil, by shielding layer grounding,
Caused electric capacity electric discharge is drawn by shielding layer grounding between primary and secondary coil, so as to improve the resistance to pressure between primary and secondary coil
Degree, generally, as shown in Figure 1, the ground wire of screen layer passes through screw rod and nut on the metal clip of device body, wherein
Metal clip is grounded with user and connected.
But for impregnated dry-type transformer after vacuum paint dipping, metal clip surface can adhere to impregnated insulating paint, this
Otherwise sample just must can influence the reliability of bonding to the thorough removing of insulated paint, and remove insulated paint while can corrode
The overlay coating of metal clip, cause impregnated dry-type transformer to cause to damage, there can be potential safety hazard in use.
The content of the invention
For above-mentioned technical problem, the purpose of the present invention is：It is high to propose a kind of shielding line Earthing Reliability
The shielding line ground structure of impregnated dry-type transformer coil.
What the technical solution of the present invention was realized in：A kind of shielding line ground connection of impregnated dry-type transformer coil
Structure, including the combination of metal clip, fastener, coil shielding line, the T-shaped pad of insulation and insulation plain cushion, the metal clip with it is tight
Firmware combinations are fixedly linked, and the coil shielding line is fixedly connected in fastener combination；The fastener combination and metal clip
Insulate T-shaped pad and insulation plain cushion are provided between part.
Preferably, also it is fixedly connected with user's ground link in the fastener combination.
Preferably, the fastener combination includes screw rod and multiple nuts.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
A kind of shielding line ground structure of impregnated dry-type transformer coil of the present invention program, by metal clip with
The T-shaped pad of insulation and insulation plain cushion are added between fastener combination, makes fastener combination completely separated with metal clip, improves
The reliability of coil shielding line ground connection, ensure that security when impregnated dry-type transformer uses.

A kind of shielding line ground structure of impregnated dry-type transformer coil of the present invention as shown in Figure 2, bag
Include metal clip 1, fastener combination, coil shielding line 3, the T-shaped pad 4 of insulation and insulation plain cushion 5, the metal clip 1 and fastening
Part combination is fixedly linked, and the coil shielding line 3 is fixedly connected in fastener combination；The fastener combination and metal clip
Insulate T-shaped pad 4 and insulation plain cushion 5 are provided between 1；User's ground link 6 is also fixedly connected with the fastener combination；It is described
Fastener combination includes screw rod 2 and multiple nuts 7.
The shielding line ground structure of the impregnated dry-type transformer coil of the present invention program, by metal clip 1 and tightly
Add the T-shaped pad 4 of insulation and insulation plain cushion between the axial direction of firmware combinations, 5 make fastener combination and metal clip 1 completely every
Open, improve the reliability of coil shielding line ground connection, ensure that security when impregnated dry-type transformer uses, and fasten
Part combination is directly connected with the ground wire of user, adds the Earthing Reliability of coil shielding line.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all cover within the scope of the present invention.
