The isolating withstanding voltage among the output paths, the input path and the shell of the high-voltage isolating transformer can reach 42kV, and the isolating withstanding voltage between the two output paths can reach 16kV.
Description
Technical field
The present invention relates to high voltage isolating transformer.
Background technology
Isolating transformer refers to input winding and exports winding at the electric transformer that is isolated from each other, in order to avoid accidental touch simultaneously electrified body (or because of insulation damages may with the metal parts of point) and the danger that brings, its principle is identical with common dry-type transformer, also be to utilize electromagnetic induction principle, main isolation primary power source loop, secondary circuit is floating empty over the ground, to guarantee Electrical Safety.
High voltage isolating transformer is high to the isolation requirement of withstand voltage between output and input, the shell, and is also high to the isolation requirement of withstand voltage between the multichannel output.
Summary of the invention
The object of the present invention is to provide a kind of high voltage isolating transformer, the withstand voltage height of the isolation between its output and input, the shell, the withstand voltage height of isolation between the two-way output.
For achieving the above object, technical scheme of the present invention is a kind of high voltage isolating transformer of design, one tunnel input, and two-way output comprises shell, is provided with iron core, skeleton and two line bags in the described shell; Described line bag comprises from inside to outside the armature winding of wrapping frame successively, several layers of insulating paper and secondary winding; Described skeleton is penetrated with iron core at it by the inside, position that the line bag wraps up; Described insulating paper is the 6-9 layer, the end face mutual dislocation of isolated from adjacent paper, and the puncture voltage of insulating paper is more than 7.5KV.
Preferably, the end face of described line bag is concave-convex.
Preferably, the external cord of each winding is provided with the protective ring of axially-aligned.
Preferably, described iron core is electrically connected with shell.
Preferably, each parts is fixed by the epoxy resin and the shell that solidify in the filling epoxy resin in the described shell, shell.
Preferably, the turn ratio of the primary and secondary winding of described two line bags is identical.
Preferably, the number of turn of the armature winding of described two line bags is identical.
Preferably, the turn ratio of the primary and secondary winding of described two line bags is 55: 12.
Preferably, described outer casing bottom is provided with installing hole.
Advantage of the present invention and beneficial effect are: a kind of high voltage isolating transformer is provided, and the isolation between its output and input, the shell is withstand voltage to reach 42KV, the withstand voltage 16KV that reaches of isolation between the two-way output.
High voltage isolating transformer of the present invention has following features:
It is A) primary and secondary that internal layer is elementary on same skeleton, outer hierarchical level, and this structure can increase the degree of coupling.
B) the insulating paper edge between primary and secondary adopts concavo-convex layout, increases creepage distance.
C) the inner high-tension bus-bar that connects uses several protective rings, increases the distance along the electric wire surface creepage.
D) iron core directly links to each other with shell, prevents inner buildup of static electricity.
E) volume little (volume can be 105mm*105mm*96mm), (installing hole is arranged at the bottom, can directly fix with the M8 screw) easy for installation.
F) one tunnel input 110V, two-way output 24V, gross power 30W.
