Abstract

The utility model discloses a thunder-proof transformer which is particularly suitable for the power distribution signal equipment The utility model is the improvement of the original thunder-proof transformer; the primary coil and the secondary coil of a winding are four windings; a primary coil group are a secondary coil group assembled to be arranged on an iron-core post; an insulating layer and a shielding layer are arranged between the coils. The utility model is characterized in that the casing has an integral structure; the middle position at the upper part of the casing is a semi-cylindrical hill whose inner side is provided with an air storing bag which is provided with a scavenging valve; the valve nozzle passes through to be communicated with atmosphere. The utility model which ensures that the entire signal system has safety in using electricity has the advantages of simple structure, light weight, small size, maintenance free, oil tightness, etc.

Description

Lightning protection transformer
The utility model relates to a kind of lightning protection transformer of freedom from repairs, in particular for the distribution transformer of railways train operation signalling arrangement power supply.
At present can both safe operation under any weather conditions for guarantee railway, particularly also can safe operation under the situation of lightning accompanied by peals of thunder, adopted lightning protection transformer at railway signal system, existing lightning protection transformer is divided into two kinds of dry type and wet types, bigger transformer generally is wet type, its primary coil, secondary coil is respectively on 2 iron cores, housing is connected by screw with each parts, the transformer of this structure, Supply Security is poor, when being struck by lightning, though itself is no badly damaged, but still easily with signal lamp, control cabinet, electrical equipment scaling loss such as dispatching desk, do not have the lightning protection effect of whole signal system, and volume is big, dismounting inconvenience, maintenance capacity is big, the leakiness wet goods.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and provide a kind of simple in structure, in light weight, volume is little, easy transportation and installation, oil-proof, meet the thunderbolt lightning protection transformer of Electrical Safety such as guard signal lamp, dispatching desk effectively.
The purpose of this utility model is achieved in that housing is an overall structure, housing is provided with high tension terminal, low tension terminal, by primary coil, the winding that secondary coil constitutes places in the housing, transformer oil is housed in the housing, pasta is higher than winding, the primary coil of winding, secondary coil is 4 line groups, by a primary coil group, a secondary coil group combination places on the iron core column, be provided with insulating barrier and screen between the coil, middle part, housing top is half garden shape projection, side is provided with air storage bag within it, and air storage bag is provided with scavenging air valve, and valve is chewed and passed housing and be communicated with atmosphere.
The purpose of this utility model can also reach by following technical measures: the layout of winding is to set gradually insulated terminal, insulation screen, secondary coil, insulation screen, primary coil on the iron core column of every side, and insulating is equipped with insulating barrier between every layer line circle; Housing of the present utility model is a plastic material, single injection-molded.
The utility model compared with prior art has following advantage:
1, simple in structure, removed the oil conservator on the existing transformer;
2, because housing is plastics, single injection-molded, thereby have in light weightly, and volume is little, is respectively 1/2,1/4 of similar transformer, and be convenient to transportation and install, and oil-proof;
3, need not keep in repair at ordinary times, realize the totally-enclosed of wet type transformer;
4, be suitable for using under various weather conditions, leakproof does not have the electrion phenomenon in the humid area;
5, have lightning protection, guarantee the safety utilization of electric power of whole signal system.
The explanation of accompanying drawing drawing:
Accompanying drawing is the utility model structural representation.
Among the figure: iron core column 1, insulated terminal 2, secondary coil 3, primary coil 4, insulation, screen 5, insulating barrier 6, housing 7, transformer oil 8, low tension terminal 9, high tension terminal 10, air storage bag 11, scavenging air valve 12.
Below in conjunction with drawings and Examples in detail the utility model is described in detail: as shown in the figure: housing (10) adopts special plastic material, have high temperature resistant indeformable, can be according to the customer requirements selection, guarantee not keep in repair before the deadline, housing (7) is an overall structure, be housing (7), high tension terminal (10), low tension terminal (9) is the unitary whole structure, realized the totally-enclosed of wet type transformer, the middle part of going up at housing (7) is half garden shape projection, its inboard is provided with air storage bag (11), air storage bag (11) is provided with scavenging air valve (12), valve is chewed and is passed housing (7) and be communicated with atmosphere, transformer oil (8) is housed in the housing (7), oil (8) face is higher than winding and atmospheric isolation, winding is positioned at housing (7), its primary coil (4), secondary coil (3) is 4 line groups, organize by a primary coil (4), the combination of a secondary coil (3) group places on the iron core column (1), the number of turn of each group primary coil (4) and secondary coil (3) and the number of plies are decided according to the variable size of transformer, the concrete layout of winding is to set gradually insulated terminal (2) on the iron core column (1) of every side, insulation, screen (5) (this layer screen both sides are insulating barrier), secondary coil (3), insulation screen (5), primary coil (4), insulating barrier (6), also insulating barrier (6) between every layer line circle, its primary coil (4) is connected with high tension terminal (10), and secondary coil (3) is connected with low tension terminal (9).Miniature transformer can also remove air storage bag (11) and scavenging air valve (12) and changes into vent valve, transformer oil (8) can not be full of housing (7), and when meeting thermal expansion, gas is discharged from vent valve, meet cold because housing and be that plastics become naturally is flat, chance is hot by heaving again.

Claims (3)

1, a kind of lightning protection transformer, comprise housing, iron core, primary coil, secondary coil, on housing, be provided with high tension terminal, low tension terminal, the winding that is made of primary coil, secondary coil places in the housing, and transformer oil is housed in the housing, and pasta is higher than winding, the primary coil of winding, secondary coil are 4 line groups, place on the iron core column by a primary coil group, a secondary coil group combination, be provided with insulating barrier and insulation screen between the coil, it is characterized in that:
A, housing are overall structure, and high tension terminal, low tension terminal and housing are one;
B, middle part, housing top are half garden shape projection, and side is provided with air storage bag within it, and air storage bag is provided with scavenging air valve, and valve is chewed and passed housing and be communicated with atmosphere.
