Problems solved by technology

Studies have shown that for every 2°C increase in temperature, the reliability of the product will decrease by 10%, and the service life will be shortened at the same time.
What's more serious is that if the temperature is too high, the transformer may be burned, affecting the normal operation of the power system

Embodiment Construction

[0014] The following describes the present invention in detail with reference to the drawings and specific embodiments.

[0015] Such as figure 1 As shown, the transformer with self-protection function of the present invention includes a magnetic core 1, a winding 2 and a number of pins 3. As a preference, the winding 2 is a copper foil winding, the magnetic core 1 is a circular ring, and the magnetic core 1 is The lead-out surface of the pin 3 is wrapped with a layer of tape 4 to avoid short circuit.

[0016] The temperature safety switch 6 is arranged between the winding 2 and the magnetic core 1 and connected in series in the circuit including the transformer. The temperature is collected by the temperature sensor 5. When the temperature is greater than the safe working temperature of the transformer, the temperature safety switch 6 is disconnected to protect The circuit is safe; after the temperature drops and cools down, the temperature safety switch 6 returns to the closed s...

Abstract

The invention discloses a transformer with a self-protection function. The transformer comprises a magnetic core, a winding and a plurality of pins, wherein one layer of adhesive tape covers a face, where the pins are led out, of the magnetic core. The transformer further comprises a temperature sensor and a temperature safety switch; the temperature safety switch is arranged between the winding and the magnetic core. The transformer has the beneficial effects that the adhesive tape is wrapped around the magnetic core so that the safe distance of the winding is enlarged and a short-circuit phenomenon is avoided; the temperature sensor and the temperature safety switch are additionally arranged in the transformer so that the transformer can be automatically switched off at a high temperature to protect a circuit; after cooling, the transformer can be automatically switched on to connect the circuit so as to prevent aging and burning off the transformer due to the fact that the temperature is too high; furthermore, a heat radiation shell is arranged so that the transformer can be effectively subjected to physical cooling and is convenient and practical.

Description

Technical field [0001] The invention relates to a transformer, in particular to a transformer with a self-protection function, and belongs to the field of electrical products. Background technique [0002] Transformer is an important device for power transmission and voltage conversion. It is widely used in the field of power electronics. The product cost is relatively high and the use environment is relatively harsh, so the performance requirements of the product are extremely high. Studies have shown that for every 2°C increase in temperature, the reliability of the product drops by 10% and the lifespan is shortened at the same time. What's more serious is that if the temperature is too high, the transformer may be burned, affecting the normal operation of the power system. Therefore, how to improve the service life of the transformer and improve its safety and stability is a very important subject. Summary of the invention [0003] In order to solve the deficiencies of the pr...
