Technical Field

Background

A transformer is a stationary electrical device used to transform ac voltage, current and transmit ac power. The electric energy transmission is realized according to the principle of electromagnetic induction. The transformer can be classified into a power transformer, a test transformer, an instrument transformer and a transformer for special purposes. The power transformer is one of transformers, is necessary equipment for power transmission and distribution and power consumer distribution, and can meet the requirement of long-distance power transmission.

However, in the process of long-distance power transmission, due to instability of a transmission line of the transformer, the conventional power transformer often has a very simple fault, and the whole power transmission system is broken down. Therefore, at present, many power transformers adopt a mode of combining a relay and a transformer to protect the transformer, and a relay protection device is installed in a power transformer system, so that the power transformer system has an automatic protection measure, and the safety of the power transformer system is greatly improved. However, the transformer is protected by only relying on a single relay, and the safe use requirement of the transformer is far from being met. And the measures of protecting the transformer by the existing relay are that the main circuit is directly closed, all the voltage transformation switches are cut off, and then the transformer is manually maintained, and the normal circuit is also closed, so that the use efficiency of the transformer is greatly influenced, the fault circuit cannot be automatically positioned, the risk and the fault circuit need to be manually rechecked, and the maintenance is inconvenient. The transformer can generate a large amount of heat during use, and if the heat is not dissipated timely or a fault circuit is closed, a fire is easily caused, so that the heat dissipation and the fault of the transformer need to be processed in a general working mode and a fault emergency mode.

In addition, low-frequency noise generated by most transformers and noise generated by a heat dissipation system can cause chronic damage to a human body, so that people are easy to be irritated and irritative, sometimes even lose intelligence, and nervous system diseases such as neurasthenia, insomnia and the like can be caused if the pregnant women are attacked for a long time, and if the pregnant women are in the low-frequency noise for a long time, the development of fetuses in the abdomen can be influenced. Meanwhile, the vibration shock wave generated from the outside seriously harms the longitudinal insulation of the transformer, and the vibration shock wave generated from the outside acts on the shell to cause resonance with the transformer body, so that the transformer body is greatly damaged.

Therefore, there is a high necessity for a power transformer apparatus capable of automatically protecting against a transformer failure. The invention provides an automatic protection type multi-output power transformation device, which has the advantages that an infrared temperature measurement sensor can be used for identifying an abnormal circuit in a transformer body and positioning the position of the abnormal circuit, and the abnormal circuit is automatically closed through a main control system, so that the automatic protection function is realized, automatic protection measures can be realized under the condition that a main circuit is not cut off, and the safety and the use efficiency of the transformer body are improved. And set up vibration detector and damping device, can avoid changing the vibration frequency of transformer body, made it asynchronous with external vibration frequency, avoided resonance harm.
