An explosion-proof transformer with leakage protection detection mechanism

Abstract

The invention discloses an explosion-proof transformer with a leakage protection detection mechanism, which includes a transformer main body, an explosion-proof plate and an explosion-proof power-off mechanism; the beneficial effect of the invention is that the air pressure inside the transformer main body can be the same as that of the outside, and the automatic explosion-proof effect can be achieved. Moreover, it is not affected by the internal air pressure, and after the relative plates are opened, the air inside the main body of the transformer can flow in a large area, which can not only blow away the smoke generated by the main body of the transformer, but also quickly cool down the inside, avoiding the temperature Too high will cause further damage to the wire or other mechanisms. When the explosion-proof power-off mechanism is working, under the driving effect of the servo motor, the single tooth will drive the toggle head and then drive the rotating block to rotate. The lower end of the rotating block rotates outward. Under the rotation effect of the rotating block, the main gate is opened again, and cooperates with the leakage protector to achieve double protection, further improving the leakage protection effect of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an explosion-proof transformer with a leakage protection detection mechanism. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (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...

AI Technical Summary

Problems solved by technology

[0003] However, today's transformers use leakage protectors for leakage protection, but when the leakage protectors are damaged or ineffective, this will cause a great impact if the transformer is not powered off in time after damage, and the current explosion-proof of the transformer Most of them are to strengthen the transformer body or use the principle of pressure relief to prevent explosion. These methods are greatly affected by the pressure inside the transformer, and the explosion-proof effect is poor, and most of them are one-time explosion-proof, which is difficult to reuse. There are also multiple settings for explosion-proof, cooling and smoke removal. As a mechanism, the production and use costs are high, and the failure rate is also high.
