Embodiment Construction

[0038] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0039] It should be noted that when an element is “fixed” to another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the descrip...

Abstract

The invention relates to a transformer. The transformer comprises a framework, wherein the framework is provided with a wire winding groove; a primary insulating part is arranged on the wire winding groove; the primary insulating part is further provided with a primary insulating cavity; a secondary insulating part sleeves the wire winding groove, the primary insulating part is arranged between the secondary insulating part and a groove bottom wall of the wire winding groove; the secondary insulating part is provided with a secondary insulating cavity; a primary winding is annularly arranged around the wire winding groove and is provided with the primary insulating cavity; a secondary winding is annularly arranged around the wire winding groove and is provided with the secondary insulatingcavity. According to the transformer provided by the invention, the primary insulating part and the secondary insulating part are arranged; the primary winding is arranged in the primary insulating cavity and the secondary winding is arranged in the secondary insulating cavity; the primary insulating cavity and the secondary insulating cavity are not communicated with each other and are arrangedat an interval, so that the primary winding and the secondary winding have good insulating performance and the insulation is more uniform, and a creepage phenomenon in a gap between the primary winding and the secondary winding is avoided; problems including transformer burnout caused by the creepage phenomenon and the like are avoided; the operation stability of the transformer is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a transformer and a production method thereof. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage and current. The main components include primary coils, secondary coils and iron cores. The coil has two or more windings, the winding connected to the power supply is called the primary coil or the primary winding, and the remaining windings are called the secondary coil or the secondary winding. [0003] Creepage distance refers to the shortest distance between two adjacent conductors measured along the insulating surface. [0004] The existing elevator control transformer coil usually adopts the layer winding method, the primary winding is first wound on the skeleton, and then the primary winding is covered with insulating paper, and then the secondary winding is wound. However, this winding method ...
