Abstract

The utility model relates to an upper frame improved railway signal lamp transformer, which is suitable to be as a power transformer. The upper frame improved railway signal lamp transformer which is particularly suitable for the power transformer in the lighting circuit of the color light signal machine of the railway belongs to the control device of the railway signal. The utility model is characterized in that the two sides of the upper bracket panel are provided with leading wire holes which have adaptive number with the lead wires of the transformer coil; each lead wire is connected with the screw bolts of the wiring terminal through passing through the corresponding leading wire holes; the top of the screw bolts of the terminal is provided with a concave pit which is convenient to be tested; the upper bracket is manufactured by insulating materials, and the lead wires adopt high-temperature resistant flexible wires. The utility model solves the problems that the insulating property of the existing transformer is poor, the lead wires are easy to be damaged, etc. The insulation property and the reliability of the device are increased.

Description

Upper bracket modified model lamps at signal locations of railroad transformer

The utility model upper bracket modified model lamps at signal locations of railroad transformer is applicable to power transformer, is particularly useful for power transformer in the railway light signal lamp circuit, belongs to railway signal control equipment.

China railways used BX1-34 type signaling point lamp transformer, its upper bracket is an irony, and primary and secondary lead-out wire cover is walked around upper bracket with insulating sleeve and is connected with terminal bolt on the terminal board, and this structure one is that insulation property are poor, is that lead-out wire is fragile again.

The purpose of this utility model is exactly to overcome the shortcoming that exists in the above-mentioned transformer device structure, the transformer that design a kind of insulation property height, goes between and be difficult for losing.

The purpose of this utility model can realize in the following manner.

The basic structure such as base, iron core, skeleton, coil and lead-out wire, upper bracket, terminal board, terminal bolt that keeps former transformer is constant, using former irony upper bracket instead insulating material constitutes, and on upper bracket 3, be provided with fairlead 7, the lead-out wire 5 of transformer coil passes fairlead 7 and connects binding post bolt 6, the top of bolt 6 all is provided with pit 8, fairlead 7 is located at the both sides of upper bracket panel, and the quantity of the quantity in hole and lead-out wire 5 adapts, and lead-out wire 5 is high temperature resistant flexible cord.

The utility model major advantage is: upper bracket is used insulating material instead and has then been improved complete machine insulation against ground performance, and Corrosion Protection, lead-out wire diverted via fairlead and is connected with binding post, and use high temperature resistant flexible cord instead, then lead-out wire is protected, improve reliability, use when the binding post end face has pit to be convenient to test.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is for the utility model is faced, vertical view;

Fig. 2 is for the upper bracket vertical view and A looks, the B view.

In the present embodiment, upper bracket adopts phenolic glass fiber plastic to make, have 13 diameters on the panel both sides of upper bracket 3 and be 4 millimeters fairlead 7, the lead-out wire 5 of the primary and secondary coil of transformer passes corresponding fairlead 7 respectively and is connected with binding post bolt 6, lead-out wire 5 adopts resistant to elevated temperatures fluoroplastics flexible cord, have one dark 3 millimeters, radius at the top of each binding post bolt and be 1.5 millimeters pit 8, the table stick end inserts in the hole when being convenient to carry out electric measurement, and contact reliably is difficult for slippage.

1 is base among the figure, and 2 is iron-core coil, and 4 is terminal board, and these are prior art, its structure and annexation and present just in use signal the identical of transformer of lighting a lamp.
