Description

Special multi-axis adjustable quick wrench for disassembly and assembly of transformer lead connectors

technical field

The utility model belongs to the field of transformer inspection and maintenance tests, in particular to a special multi-axis adjustable quick wrench for the disassembly and assembly of transformer lead joints.

Background technique

At present, transformers are generally overhauled within 5 years after being put into operation and every 10 years thereafter. During routine power failure tests, transformers often need to dismantle and install winding lead connectors to ensure the reliability and accuracy of test data.

The winding lead connectors of transformers usually have two columns of 6 screws on one lead connector, so it takes a lot of time to disassemble and assemble the connectors of the entire transformer.

Contents of the invention

The utility model provides a special multi-axis adjustable quick wrench for disassembling and assembling the transformer lead joints in order to solve the technical problem that a large amount of time is required for disassembling and assembling the lead joints during the maintenance of the existing transformer.

The technical scheme that the utility model takes for solving the technical problem existing in the known technology is:

The special multi-axis adjustable quick wrench for the disassembly and assembly of transformer lead connectors includes three ratchet wrenches, and each ratchet wrench is provided with a protrusion at the tail;

Through holes matching the protrusions are arranged on the fixing splint, and the rear ends of the three ratchet wrenches are installed in the through holes of the fixing splint through the protrusions.

Further, the front end of the ratchet wrench is also fitted with a fixed sleeve, and the fixed sleeve is provided with three installation grooves matching the ratchet wrench.

Further, multiple sets of through holes matching the protrusions are provided on the fixing splint.

The utility model has the advantages and positive effects: the special multi-axis adjustable quick wrench for the disassembly and assembly of transformer lead joints simplifies the disassembly and assembly process of transformer lead joints, saves routine test time during power outages, and saves precious on-site working time. When working, three screws can be disassembled and assembled at the same time; they can also be combined freely according to needs. For multiple screws and bolts of the same specification, simultaneous disassembly and assembly can be realized.

Description of drawings

Fig. 1 is a structural schematic diagram of a multi-axis adjustable quick wrench specially used for the disassembly and assembly of transformer lead joints provided by the embodiment of the utility model;

In the figure: 1, fixed splint; 2, through hole; 3, protrusion; 4, ratchet wrench; 5, fixed sleeve clip.

detailed description

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are given below in conjunction with the accompanying drawings.

Below in conjunction with Fig. 1, the structure of the present utility model is described in detail.

The special multi-axis adjustable quick wrench for the disassembly and assembly of transformer lead connectors includes three ratchet wrenches 4, and each ratchet wrench 4 is provided with a protrusion 3 at the tail;

The fixing splint 1 is provided with a through hole 2 matching the protrusion 3 , and the rear ends of the three ratchet wrenches 4 are installed in the through hole 2 of the fixing splint 1 through the protrusion 3 .

Further, the front end of the ratchet wrench 4 is also fitted with a fixed sleeve clip 5 , and the fixed sleeve clip 5 is provided with three installation grooves matching the ratchet wrench 4 .

Further, multiple sets of through holes 2 matching the protrusions 3 are provided on the fixing splint 1 .

The structure of the utility model is further described below in conjunction with working principle.

Based on a single ratchet quick wrench, it can realize two-way rotation, which is convenient for disassembly, assembly and replacement. Punch holes at the tail of each ratchet wrench 4, and fix it with a fixed splint 1 at the tail. There are a plurality of protrusions 3 on the ratchet wrench 4, and a plurality of sets of through holes 2 are arranged on the fixing splint 1, so that the distance between the ratchet wrench 4 can be adjusted, thereby adapting to lead connectors of different specifications. The head of the 4 sets of fixed ratchet wrenches is covered with a fixed sleeve 5, and the 4 sets of ratchet wrenches are further fixed to ensure the stability of the ratchet wrench 4 during use. It can greatly save the time for dismantling and assembling the winding lead joints on the site of the transformer power failure routine test, improve the efficiency of the routine test, and ensure the reliability of the data during the test.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modifications made to the above embodiments according to the technical essence of the present utility model are equivalent to changes and modifications. All belong to the scope of the technical solution of the utility model.
