Problems solved by technology

[0004] Transformers generally have low-voltage bushing parts, which are used as insulating parts for lead wires. However, in actual use, such parts are prone to certain problems. The low-voltage bushings are often in an open state, forming a safety hazard. Especially in places with a large flow of people or places where children often come and go, it is often easy to cause wanton contact or damage to the low-voltage bushing by outsiders
In addition, this kind of low-voltage bushing is also a vulnerable part, and it is easy to be damaged by external rain erosion and physical damage, which also forms a certain safety hazard

[0038] combine Figure 9 As shown, elastic pads 41 are provided in the first semicircular groove 32 and the second semicircular groove 33, and the elastic pads 41 are used for clamping and fixing the pressing sleeve 11; the top of the left containing body 21 has a second An extension plate 42 with a screw hole and an extension plate 43 with a second screw hole, the first screw hole 42 and the second screw hole 43 are fastened by bolts 44;

[0039] In the step of S3, when the left containing body 21 and the right containing body 22 are close together, the extension plates 42, 43 are fastened together by bolts 44, and at the same time, the elastic pad 41 forms a pressing action, so that The gap 45 in the clamping space 34 is sealed by the elastic pad 41 .

no. 3 example

[0041] combine Figure 7 and Figure 8 As shown, the outer position of the top wall 39 of the left containing body 21 is provided with a stretching body 51, and the stretching body 51 is connected to the top end of the shaft 28 through a second spring 52;

[0042] The working method includes the following steps:

[0043] It also includes S4: tilting the stretching body 51 with a tool, so that the stretching body 51 moves away from the shaft 28, and the stretching body 51 stretches the second spring 52, so that the second spring 52 drives the shaft 28 upward Move, so that the limit head 29 of the limit member 26 is free from the restraint of the limit groove 36, and then under the action of the first spring 27, the turning lever 25 is driven to rotate around the support point. Through the upward pulling action of the effect of the stretching body 51, the second spring 52 drives the shaft 28 and the limit head 29 to break away from the restraint of the limit groove 36, thereby...

Abstract

The present invention relates to a fitting set for transformer erection and its working method, which has a protective effect on low-voltage bushings of transformers. It includes a transformer lead wire, a low-voltage bushing and a fitting assembly, and the low-voltage bushing is sleeved on the lead wire; the fittings assembly has a left accommodating body and a right accommodating body, and both the left and right accommodating bodies are hollow structures. The left accommodating body and the right accommodating body are detachably connected for protecting the low-voltage bushing. The metal fitting set for transformer erection provided by the invention has a good protective effect on the low-voltage bushing of the transformer, avoids interference and wanton destruction by external factors, prolongs the service life and improves the safety.

Description

technical field [0001] The invention relates to the technical field and belongs to the field of electric power protection, in particular to a fitting set used in transformer erection and a working method thereof. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] Armor clamps are iron or aluminum metal accessories often used in power transmission lines, collectively referred to as armour clamps. Most of the fittings need to withstand large tension during operation, and some of them also need to ensure good electrical contact. [0004] Transformers generally have low-voltage bushing parts, which are used as insulating parts for lead wires. However, i...
