Embodiment Construction

[0016] Attached below figure 1 An embodiment of the present invention is described.

[0017] The step winding method of transformer type sensor coil includes the following steps:

[0018] 1) Wrap the alkali-free glass fiber cloth 2 impregnated with insulating varnish on the outer surface of the winding area of ​​the skeleton 1, and the outer surface of the winding area of ​​the skeleton 1 is wrapped with two layers of alkali-free glass fiber cloth 2 to improve the insulation performance of the skeleton 1 .

[0019] 2) Put the wrapped skeleton 1 into a drying box, heat it up to 200°C, keep it warm for 2 hours, and take it out;

[0020] 3) Wind the enameled round copper wire 4 in the winding area of ​​the skeleton 1 after drying. For each layer, apply a layer of insulating varnish on the enameled round copper wire 4 until the specified number of layers are wound in parallel. The primary coil 5 and the secondary coil 6 are wound;

[0021] 4) The enameled round copper wire 4 is wound in ...

Abstract

The invention provides a ladder winding method for a transformer type sensor coil. The ladder winding method comprises the following steps of: wrapping the outer surface of a framework winding region for two circles by using non-alkali glass fiber cloth dipped with insulating varnish; then drying; flatly winding an enamel round copper wire at the framework winding region, and brushing the insulating varnish once when one layer of the enamel round copper wire is wound; after the layers of the specified number are flatly wound, continuously winding the enamel round copper wire in a specified region according to requirements, and brushing the insulating varnish once when one layer of the enamel round copper wire is wound; after the winding is completed, wrapping the coil for two circles by using a polytetrafluoroethylene film; then wrapping the coil for two circles by using the non-alkali glass fiber cloth; then binding by using cotton threads; and finally drying. After a sensor is assembled by using the coil wound by the invention, the sensor is mounted on a spout afterburner fuel regulator and is used for completing test run and check test run together with an engine, and special use requirements of the engine can be completely satisfied.

Description

Technical field [0001] The invention relates to the technical field of transformer-type sensors, in particular to a method for winding a transformer-type sensor coil in steps. Background technique [0002] Transformer type sensor is mainly used for displacement measurement. Its working principle is composed of two or more inductance coils with iron core. The coupling between the primary and secondary coils can change with the relative movement between the armature or the two coils. , That is, the measured displacement can be converted into the change of the mutual inductance of the sensor. When the voltage with the appropriate frequency excites the primary winding, the output voltage of the secondary coil will change with the change of the mutual inductance, thereby converting the measured displacement into a voltage output. A certain type of linear displacement sensor is a transformer type sensor, which is matched with a certain type of aero engine. It is installed on the nozzle...
