Description

A Transformer with Replaceable Insulation Mat

technical field

The utility model relates to the field of bookstore equipment, in particular to a replaceable insulating pad transformer.

Background technique

The transformer uses the principle of mutual inductance. The 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 conversion, current conversion, impedance conversion, Isolation, voltage stabilization (magnetic saturation transformer), etc., can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. etc. According to the existing technology, the transformer mainly winds the primary coil and the secondary coil sequentially on a single coil, and the core is combined with the coil frame through the through hole of the coil frame. In order to avoid electric leakage or other accidents, usually the core An insulating pad is erected between the coil frame and the magnetic core, but the magnetic core will generate heat during work, which will promote the aging of the insulating pad and reduce the service life of the transformer. Therefore, the utility model proposes a new type of transformer with a replaceable insulating pad.

Utility model content

The purpose of this utility model is to provide a transformer with a replaceable insulating pad to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a replaceable insulation pad transformer, including transformer housing, air inlet, input wire, air outlet, exhaust fan, output wire, transformer coil, coil frame, magnetic core, insulation Pads, protrusions, handles, the air inlet is located on the left side of the transformer housing, the input wire is located on the left side of the transformer housing, the air outlet is located on the right side of the transformer housing, the exhaust fan is located at the air outlet, the The output wire is located on the right side of the transformer housing, the transformer coil is located inside the transformer housing, the magnetic core is located in the coil frame, the insulating pad is located between the coil frame and the magnetic core, and the protrusion is located at the tail of the insulating pad. The handle is located at the end of the insulating pad.

Preferably, an air inlet is provided on the left side of the transformer housing, an air outlet is provided on the right side, and an exhaust fan is provided at the air outlet.

Preferably, the insulating pad is located between the coil frame and the magnetic core.

Preferably, the protrusion is located at the tail of the insulating pad.

Compared with the prior art, the beneficial effect of the utility model is that the replaceable insulating pad transformer is provided with an air inlet and an air outlet, and an exhaust fan is provided at the air outlet, which ensures heat dissipation, prolongs the practical life, and reduces fire hazards. Hidden danger, the insulating pad is set between the coil frame and the magnetic core. The insulating pad is a rubber pad with low cost and deformation ability. The protrusion limits the extreme position of the insulating pad, and the insulating pad can be pulled out for replacement.
