CN203375057U - Three-way tool special for vacuum oil injection - Google Patents

Abstract

The utility model relates to a special three-way tool for vacuum oiling, which comprises a three-way main body and screw joints fixedly connected with three ports of the three-way main body respectively, the said three-way main body is fixedly connected with a supporting plate, and the said supporting A bottom plate with nail holes is arranged on the board, and a dustproof cover is arranged on the threaded joint. When the utility model is used for vacuum oil filling of the transformer, the threaded joints fixedly connected with the three ports of the tee main body are respectively connected with the transformer and two oil tanks, and the valve of the first oil tank is first opened for oil filling. When the oil in one oil tank is exhausted, close the valve of the first oil tank and open the valve of the second oil tank to continue filling oil without disassembling and switching the oil filling pipeline, which saves manpower and time and improves work efficiency while avoiding air entering the transformer when reversing oil injection lines.

Description

A special tee tool for vacuum oiling

technical field

The utility model relates to a special three-way tool for vacuum oiling.

Background technique

During the installation or maintenance of transformers, it is often necessary to vacuum oil the transformers. The insulating oil of a 220kV transformer is generally about 40 tons, but the commonly used oil tank capacity is generally 25 tons, which requires two oil tanks to fill the transformer with oil, and the oil filling pipeline needs to be reversed during the oil filling process, so that Not only is it time-consuming and labor-intensive, but also it is easy for air to enter the transformer during the process of changing the oil pipe.

Utility model content

The technical problem to be solved by the utility model is to provide a special three-way tool for vacuum oiling, which is simple in structure and easy to use, and can avoid reversing the oil pipe during the vacuum oiling process of the transformer.

The utility model adopts the following technical solutions:

The utility model comprises a three-way main body and threaded joints fixedly connected with three ports of the three-way main body respectively, the said three-way main body is fixedly connected with a support plate, and the support plate is provided with a bottom plate with nail holes, so The above threaded joint is provided with a dust cover.

The positive effect of the utility model is as follows:

When the utility model is used for vacuum oiling of the transformer, since the support plate fixedly connected with the tee main body is provided with a bottom plate, it can be placed stably, and steel nails can be used to fix it on the ground through the nail holes provided on the bottom plate, and then Connect the threaded joints fixedly connected to the three ports of the tee main body with the transformer and the two oil tanks respectively, first open the valve of the first oil tank for oil filling, and when the oil in the first oil tank is used up, close it Open the valve of the first oil tank, open the valve of the second oil tank, you can continue to inject oil, no need to disassemble and replace the oil injection pipeline, save manpower and time, improve work efficiency, and avoid the need to reinstall the oil injection pipeline Air enters the transformer during commutation.

Description of drawings

Accompanying drawing 1 is the schematic structural diagram of the main view of the utility model;

Accompanying drawing 2 is the utility model top view structure diagram.

In the accompanying drawings: 1 threaded joint, 2 support plate, 3 bottom plate, 4 tee main body, 5 dust cover, 6 nail hole.

Detailed ways

Shown in accompanying drawing 1, 2 is a specific embodiment of the utility model, and the utility model comprises a three-way main body 4 and threaded joints 1 fixedly connected with three ports of the three-way main body 4 respectively, and the described three-way main body 4 It is fixedly connected with the support plate 2, the support plate 2 is provided with a bottom plate 3 with nail holes 6, and the threaded joint 1 is provided with a dustproof cover 5. When the utility model is used for vacuum oiling of the transformer, since the support plate 2 fixedly connected with the tee main body 4 is provided with a base plate 3, it can be placed stably and fixed on the ground through the nail holes 6 provided on the base plate 3 , and then connect the threaded joints 1 fixedly connected to the three ports of the tee main body 4 with the transformer and the two oil tanks respectively, first open the valve of the first oil tank for oil filling, when the oil in the first oil tank is used When it is exhausted, close the valve of the first oil tank and open the valve of the second oil tank to continue filling. When finished using, the mouth of threaded joint 1 is blocked with dust cap 5 to prevent dust from entering. When the utility model is used for vacuum oiling of the transformer, there is no need to disassemble and replace the oil filling pipeline, which saves manpower and time, improves work efficiency, and avoids air entering the transformer when the oil filling pipeline is switched.
