Description

A kind of power switch cabinet matched with devices High-Isolation Transformer

Technical field

The utility model belongs to transformer technology field, particularly relates to the power switch cabinet matched with devices High-Isolation Transformer used in a kind of hot and humid environment.

Background technology

As everyone knows, transformer (Transformer) utilizes 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 buck/boost, matched impedance, Secure isolation etc.Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.

In recent years, along with the fast development of power equipment, the scope of application of transformer is more and more extensive, but at some Code in Hazardous Special Locations, in such as hot and humid environment, the security performance of traditional transformer is difficult to the work ensureing that its safety is permanently effective, therefore, be directed to the feature of hot and humid environment, design and develop a kind ofly have to seem it is particularly important compared with the power switch cabinet matched with devices High-Isolation Transformer of high insulating property.

Utility model content

The technical problems to be solved in the utility model is: provide a kind of instructions for use that can meet hot and humid environment, has the power switch cabinet matched with devices High-Isolation Transformer compared with high insulating property.

The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:

A kind of power switch cabinet matched with devices High-Isolation Transformer, comprises fixture (4), (3), line bag (2) unshakable in one's determination, winding coil and binding post (1); Described iron core (3) outer wall is cast with three layers of transparent epoxy layer; Described winding coil comprises primary coil and secondary coil; The binding post (1) of described primary coil is built-in type copper nut, and described built-in type copper nut is electrically connected with the lead-out wire of line bag (2); The input voltage of described power switch cabinet matched with devices High-Isolation Transformer is 380V, the output voltage of described power switch cabinet matched with devices High-Isolation Transformer is 590V, and the power bracket of described power switch cabinet matched with devices High-Isolation Transformer is 4KVA ~ 10KVA; Be fixedly connected with by screw rod between described fixture (4) with (3) unshakable in one's determination.

Further: described line bag (2) is made up of A phase line bag, B phase line bag and C phase line bag; Epoxy resin is cast with respectively at A phase line bag, B phase line bag and C phase line encrust; The quantity of described winding coil is ten, and the binding post quantity of described winding coil is 20.

The advantage that the utility model has and good effect are:

Because iron core (3) outer wall in the utility model is cast with three layers of transparent epoxy layer; Therefore form high insulation between iron core and line bag, ensure that the generation without spill over phenomenon under high voltage electric field well;
