Problems solved by technology

Firstly, it is necessary to install the switch supporting plate on the transformer clamp, then install the switch on the supporting plate, and then connect the tap outlet of the voltage regulating coil to the switch terminal. Provide appropriate operating space for the switch assembly, so that the position of the voltage regulating lead wire of the transformer should not only consider the insulation distance, but also the assembly distance

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] like Figure 1~3 As shown, the present invention includes a switch support plate 1, a vertical pole 2 and a cross bar 3, wherein the vertical pole 2 is arranged vertically and its upper end is fixedly connected with the switch support plate 1, and the cross bar 3 is arranged horizontally and between two adjacent poles 2 The crossbar 3 and the vertical pole 2 form a frame structure, the upper end of the tap changer 4 is installed on the switch support plate 1, and the body of the tap changer 4 is placed in the frame. After the pressure lead wire 5 is connected to the joint on the tap switch 4, it is bandaged and insulated, and the joint is reserved. The voltage regulation lead wire 5 can be bound on the frame, so that the tap changer 4, the frame and the voltage regulation lead wire 5 can pass through the suspension together. Rope 6 overall hoisting, s...

Abstract

The invention relates to the technical field of transformers, in particular to a transformer voltage regulating lead wire assembling method which comprises the following steps of: 1, adjusting the length of vertical rods; 2, installing the upper end of a tap switch on a switch supporting plate, fixedly connecting the upper ends of the vertical rods with the switch supporting plate, then connecting the adjacent vertical rods through using transverse rods to form a frame, and arranging the tap switch in the frame; 3, connecting a voltage regulating lead wire with a joint on the tap switch, and then fixing the voltage regulating lead wire on the frame; 4, after coil sleeving of a transformer is completed, integrally hoisting and assembling the frame, the tap switch and the voltage regulating lead wire on a transformer body; and 5, assembling the voltage regulating lead wire with a corresponding reserved joint on a transformer coil to complete assembling of the voltage regulating lead wire. According to the transformer voltage regulating lead wire assembling method, the voltage regulating lead wire and the tap switch are assembled independently, and then the tap switch and the voltage regulating lead wire are integrally mounted on the transformer body to be connected, so that the assembly quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a method for assembling voltage regulating lead wires of transformers. Background technique [0002] In order to meet the voltage fluctuation of the power system, the transformer usually needs to adjust the voltage. Generally, the voltage regulation can be realized by setting the voltage regulating coil and connecting each tap of the voltage regulating coil with the voltage regulating switch. The connecting line is Regulator leads. Generally, the transformer has many tap stages, so the structure of the voltage regulating lead wire is usually more complicated, and the assembly of the voltage regulating lead wire is the most time-consuming process in the assembly of the transformer lead wire. [0003] Generally, the assembly of the voltage regulating lead wire of the transformer needs to be assembled on the body of the transformer after the transformer coil assembly is comple...
