Problems solved by technology

[0002] It is inevitable that the transformer will vibrate during operation, and the vibration will inevitably cause the fastening bolts to loosen. The iron core straps also face this problem. If the fastening bolts of the pull straps are loose, the pull straps will fall off, and the high voltage of the transformer body will be easily damaged. Discharge of the pull strap or the pull strap itself short-circuits a part of the coil of the transformer itself, which will cause a safety accident and affect the normal operation of the transformer

Embodiment Construction

[0014] Such as Figure 1 to Figure 7 as shown,

[0015] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the present invention includes two drawstring fixing plates 1, two of which are fixedly welded on the transformer body, a U-shaped card slot is arranged on the fixed plate, an insulating sleeve is clamped in the U-shaped card slot, and two draw belts 3 The end is insulated from the fixed plate 1 through the insulating sleeve 2 and fixed on the fixed plate 1, and the grounding lead 5 and the ground bolt 4 fixed on the fixed plate 1 form a safe grounding method with only one point grounding with the fixed plate 1.

[0017] The installation process is as follows Figure 2 to Figure 7 As shown, the installation process is as follows: slide the two ends of the drawstring 3 in...

Abstract

The invention discloses a fixed structure of a transformer drawstring, comprising a transformer body, wherein the transformer body is welded with two drawstring fixed boards; the two ends of the drawstring are tightly fixed on the fixed boards; each of the fixed board is provided with a U-shaped slot, wherein an insulating sleeve is clamped in the U-shaped slot; the two ends of the drawstring are respectively pressed in the insulating sleeves tightly to form a fixed structure; and at least one fixed board is provided with a group of grounded bolts, and a grounded lead is connected between the grounded bolts and the drawstring to guarantee that the drawstring is grounded only at one point. The fixed structure of the transformer drawstring avoids the occurrence of transformer drawstring dropping by improving the fixing way of the drawstring and is simple in structure of the transformed scheme and convenient to use and install, so that the structure can effectively fix the transformer drawstring, prevent the transformer drawstring from dropping and fulfills the requirement of long-term safe operation of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a fixing structure for a transformer drawstring. Background technique [0002] It is inevitable that the transformer will vibrate during operation, and the vibration will inevitably cause the fastening bolts to loosen. The iron core straps also face this problem. If the fastening bolts of the pull straps are loose, the pull straps will fall off, and the high voltage of the transformer body will easily damage the transformer. The discharge of the pull strap or the pull strap itself short-circuits a part of the coil of the transformer itself will cause a safety accident and affect the normal operation of the transformer. Contents of the invention [0003] The invention provides a transformer strap fixing structure, which has a simple structure, is convenient to use and install, can more effectively fix the transformer strap, avoids the accident of the transformer strap falli...
