A transformer anti-burning protection device and using method

Abstract

The invention discloses a transformer burning-preventive protecting device comprising an oil tank. An auxiliary oil tank is arranged on the oil tank, an external oil cooling mechanism communicated with the oil tank is arranged on one side of the oil tank, an oil pump is arranged on a pipeline used for communicating the external oil cooling mechanism with the oil tank, and an automatic monitoring and controlling mechanism is connected to the oil pump. By the transformer burning-preventive protecting device, cooling oil in the oil tank can be cooled thoroughly, cooling efficiency of the cooling oil in the oil tank is quite low, cooling rate is quite high, and temperature is reduced to 5-10 DEG C in one minute; automatic adjustment can be performed according to temperature of the cooling oil in a transformer, real-time monitoring and controlling on temperature and liquid level of the cooling oil in the oil tank are realized, and remote alarming can be realized to notify electrical technicians of oil leakage of the transformer; current and voltage information of transformer operation can be sent to an electrical background in real time, convenience is brought to the electrical technicians to monitor operation situations of the transformer and to schedule electric energy, and the transformer burning-preventive protecting device has good promotion and application value.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a transformer anti-burning protection device and a use method. technical background [0002] The functions of power transformers are power transmission, voltage conversion and insulation isolation, and are widely used in power supply technology and power electronics technology. During the working process of the transformer, the internal windings and iron cores will generate losses and convert them into heat energy, which will increase the temperature of the transformer and affect the performance of the transformer. Therefore, it is necessary to cool down the transformer. [0003] Oil-immersed power transformers are cooled by oil as a cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, forced oil circulating air cooling and forced oil circulating water cooling, etc. In order to dissipate the heat absorbed by the oil, usually in the transformer ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1) The above heat dissipation method cannot completely cool the cooling oil in the oil tank, the cooling efficiency of the cooling oil in the oil tank is extremely low, and the cooling speed is slow

2) It cannot be adjusted automatically according to the temperature of the cooling oil in the transformer

3) Real-time monitoring and control of the temperature in the fuel tank cannot be realized

4) It cannot monitor the liquid level of the cooling oil in the oil tank in real time, and it will not alarm to remind people around that the transformer is faulty, and it cannot remotely alarm to notify the power personnel that the transformer is short of oil

5) The current and voltage information of the transformer operation cannot be sent to the power management platform in real time, which is inconvenient for the power personnel to monitor the operation of the transformer, and it is inconvenient for the power personnel to perform power scheduling

6) It is necessary to have a manual on-duty transformer to observe the operation of the transformer. When heat dissipation is required, the oil pump is turned on, which is time-consuming and wastes precious human resources; or the oil pump is always running, and the oil pump is easily damaged, resulting in equipment failure and serious losses.
