Power transformer with operating state alarm

Abstract

The invention discloses a power transformer with an operating state alarm. The power transformer comprises a voltage transformation shell, a connecting hole is formed in the top of the voltage transformation shell, the portion, close to the left side of the connecting hole, of the top of the voltage transformation shell is fixedly connected with the bottom of an alarm lamp, the connecting hole issleeved with an electrode connecting column,the bottom of the voltage transformation shell inner electrode connecting column is fixedly connected with the top of the voltage transformation body, the bottom of the voltage transformation body is fixedly connected with the top of the supporting frame, the bottom of the supporting frame is fixedly connected with the bottom in the voltage transformation shell, and the left side of the voltage transformation shell is fixedly connected with the right side of the alarm shell. According to the power transformer with the operating state alarm, the motordrives the smoke suction fan to rotate all the time, when the transformer is on fire, a smoke suction fan can suck smoke caused by the fire in the voltage transformation shell into the smoke inlet sleeve at the first time, the smoke sensor in the smoke inlet sleeve senses the smoke, a buzzer and an alarm lamp work, and an alarm signal is sent out in time, therefore, the fire is prevented from diffusing, and a large fire hazard is avoided.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a power transformer with an operating state alarm. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). The transformer is roughly composed of an iron ...

AI Technical Summary

Problems solved by technology

[0003] The existing transformers have relatively simple functions and can only realize the voltage transformation function, and cannot monitor the self-generated operating status in real time during operation. When a fire occurs in the transformer itself due to unstable voltage and high current, it cannot be timely carried out alarm, and the existing transformer mounted on the utility pole can be directly exposed and placed on the utility pole, which can easily cause damage to the transformer, so it is necessary to invent a power transformer with an operating status alarm
