Abstract
The utility model discloses a transformer with a shielding device. The transformer comprises a transformer body, a shielding shell covered on the transformer body, a coil arranged in the transformer body, a primary junction box arranged on one side of the transformer body, a junction box cover connected with the primary junction box and a secondary junction box arranged on the other side of the transformer body, wherein the shielding device is arranged between the primary junction box and the junction box cover. The structure of the transformer is improved so that the effect of shielding electricity and magnetism is greatly improved, mutual interference between devices is reduced, the function of the transformer is fully exerted and the working reliability of the electric appliances is improved.
Description
Technical field
The utility model relates to a kind of transformer, specifically has the transformer of screening arrangement.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, be commonly used for lifting voltage, matched impedance, safety isolation etc.The function of transformer mainly contains: voltage transformation; Current transformation; Impedance conversion; Isolate; Voltage stabilizing (magnetic saturation transformer); Autotransformer; High-tension transformers (dry type and oil immersed type) etc., the core configuration that transformer is commonly used generally has E type and C sections core, XED type, ED type CD type.
Under some particular job environment, be equipped with numerous electronics, electric equipment, so electromagnetic environment is very abominable, the phase mutual interference between the equipment is quite serious, this not only influences the functional reliability of equipment, also influences giving full play to of its function.Common transformer does not adopt quarantine measures such as electric screen and magnetic screen, though can be to the less demanding power consumption equipment power supply of some Electro Magnetic Compatibilities, but just might be subjected to the conducted interference of power supply unit to the sensitive equipment power supply that has Electro Magnetic Compatibility to require, the functional reliability of power consumption equipment is exerted an influence.
The utility model content
The utility model purpose: at the existing problem and shortage of above-mentioned existing longitudinal cable connector, the purpose of this utility model provide a kind of can effectively shield electricity with magnetic, reduce the transformer that equipment room interferes with each other.
Technical scheme: for achieving the above object, the technical solution of the utility model is a kind of transformer with screening arrangement, comprise the transformer body, be covered in screening can on the transformer body, be arranged on the transformer body interior coil, be arranged at the elementary terminal box of transformer body one side, the connector cover that joins with elementary terminal box and the secondary terminal box that is arranged at transformer body opposite side, wherein between elementary terminal box and connector cover, be provided with screening arrangement.
For guaranteeing shield effectiveness, described screening arrangement comprises stainless steel strip that joins with connector cover and the conductive rubber that joins with elementary terminal box opening part.
Described stainless steel strip is welded on the connector cover.
Beneficial effect: the utility model is by to the architecture advances of transformer, makes effect of its shielding electricity and magnetic improve, reduce phase mutual interference between the equipment greatly, make its function be not fully exerted, improve the reliability of power consumption equipment work.
