Oil immersed transformer thermometer base
Technical Field
The utility model provides an oil immersed transformer thermometer base, and belongs to the technical field of transformers.
Background
A transformer is a device that changes an ac voltage using the principle of electromagnetic induction. The transformer can be classified into a power transformer, a full-sealed transformer, a combination transformer, a dry transformer, an oil-immersed transformer, a single-phase transformer, and the like according to the application. The oil immersed transformer is an indispensable one in the transformer, is one of important equipment in industrial and mining enterprises and civil building power supply and distribution systems, and is widely used indoors and outdoors.
When the oil immersed transformer thermometer is installed, the thermometer probe is screwed into a thermometer seat installed on the transformer oil tank through threads, in this case, once the thermometer seat is installed in error, the thermometer seat with the size of the thread A is welded into the thermometer seat with the size of the thread B, after the transformer is assembled, the problem is found to change the thermometer seat, transformer oil in the transformer oil tank needs to be discharged, the correct thermometer seat is changed again, and transformer oil is injected again, and the process needs to filter the transformer oil again, so that the cost of the transformer is increased, and the manufacturing time of the transformer is increased. Based on the above, the utility model provides the oil immersed transformer thermometer base.
Disclosure of utility model
The utility model solves the technical problem that the change of the thermometer base of the oil immersed transformer can greatly influence the cost and the manufacturing time.
In order to solve the technical problems, the oil immersed transformer thermometer base comprises a transformer oil tank, wherein a through hole is formed in the transformer oil tank, a transformer flange arranged outside the through hole is arranged on the side wall of the transformer oil tank, a thermometer base is arranged on the side wall of the transformer flange, a bolt fixedly connected with the transformer flange is arranged on the thermometer base, a thermometer pipe penetrating through the through hole and inserted into the transformer oil tank is arranged in the center of the thermometer base, and an adapter in threaded connection with the thermometer pipe is arranged at the top of the thermometer base.
Further, a through hole for the thermometer tube to pass through is formed in the transformer flange, and the transformer flange and the transformer oil tank are welded and fixed together.
Further, the circumference is equipped with a plurality of mounting holes with bolt matched with on the thermometer base, the circumference is equipped with the flange hole that link up mutually and match with the bolt with the mounting hole on the transformer flange.
Further, the center of the thermometer base is provided with a center hole, and the top of the thermometer tube is welded and fixed inside the center hole.
Further, the lower part of the adapter is provided with a threaded connecting pipe, the threaded connecting pipe is provided with external threads, and the top of the inner wall of the thermometer tube is provided with internal threads matched with the external threads.
The utility model has the beneficial effects that:
The thermometer base is fixedly arranged on the transformer flange through the bolt, so that the thermometer tube is inserted into the transformer oil tank of the oil immersed transformer, the disassembly and assembly work of the thermometer tube and the adapter can be conveniently realized under the cooperation of the external thread and the internal thread, if the installed adapter is wrong in size, the adapter with the correct thread size is matched with the corresponding thermometer tube, the process of replacing the adapter does not need to drain oil, inject oil and filter oil, and the cost and the manufacturing time are not greatly influenced relative to the change of the thermometer base of the traditional oil immersed transformer.
