Description

Contact pin type band shell transformer

Technical field

The utility model relates to transformer technology field, is specifically related to a kind of contact pin type band shell transformer.

Background technology

Transformer uses very general in various machinery equipment, and Electrical Safety is the major issue of transformer production always, and the insulation property of transformer and electricity protection arrange and can not be ignored; In the use of transformer, if during the situations such as circuit for generating short circuit, overload or overvoltage, easily cause transformer and catch fire, transformer can be caused damage, the useful life of transformer is had a greatly reduced quality.

Summary of the invention

The purpose of this utility model is to provide a kind of contact pin type band shell transformer, improves the insulation property of transformer, make the use of transformer safer, install more convenient.

In order to achieve the above object, the utility model adopts following technical scheme:

Contact pin type band shell transformer, comprises shell, silicon steel sheet, skeleton, stitch and winding:

Skeleton comprises the pedestal and two pieces of division boards that two cross sections are E type, each cross section is that the pedestal of E type comprises plate in one piece of riser, two end plates and a piece, two end plates lays respectively at riser two ends, middle plate is positioned in the middle part of riser, in two end plates and one piece, plate is parallel to each other, two cross sections are that the pedestal of E type is staggered relatively, two pieces of division boards are positioned over the middle plate both sides that cross section is the pedestal of E type respectively, comprise three spaces in skeleton, comprise two pieces of division boards and two middle the plates isolation part formed and two spaces being positioned at both sides, isolation part;

Armature winding and secondary winding are placed in the space of both sides, isolation part respectively;

Multiple being stacked together of silicon steel sheet is interspersed in skeleton;

Shell comprises skeleton, and marginal portion and the transformer bottom of multiple silicon steel sheet stacked are exposed to outside;

Connect stitch bottom skeleton, stitch is extended out by transformer bottom.

In the contact pin type band shell transformer that the utility model provides, the skeleton structure of dual grooved and the setting of isolation part, avoid first armature winding and directly contact with secondary winding and cause short circuit, strengthen primary and secondary insulation, improves insulation property; Shell protection kernel component is set; The setting of direct insertion stitch makes the installation of transformer quicker, convenient.

One as the utility model contact pin type band shell transformer is improved, and shell is provided with insulation cover.Be provided with insulation cover just without the need to carrying out electrostatic screen; When transformer output is short-circuited because of reasons such as faulty operations, the existence of insulating coating avoids transformer and catches fire, can effective trouble-saving generation, reduce severity of injuries.

One as the utility model contact pin type band shell transformer is improved, and silicon steel sheet is that cold-reduced silicon sheet is made, and armature winding and secondary winding are the coiling of enamelled wire closed assembly.Cold-reduced silicon sheet iron loss is low, and magnetic flux density is high, and evenly, can improve activity coefficient, and leakage field being low, loss is little, is select as the high-quality of transformer core for surfacing, thickness; Enamelled wire possesses the standard performance as winding wire, and with low cost, commonly uses and is easy to get, be conducive to controlling cost.

One as the utility model contact pin type band shell transformer is improved, and the shell of employing is plastic shell.Plastic shell can protect kernel device, avoids kernel device surprisingly to receive infringement easily, reinforced insulation simultaneously because colliding, falling etc.

The beneficial effects of the utility model are, structure is simple and clear, and the dual grooved structure of skeleton and the setting of isolation part can strengthen primary and secondary insulation, improve insulation property; The setting of direct insertion stitch makes the installation of transformer quicker, convenient; Plastic shell colliding, to fall etc. unexpected in protect installed with built-in component not impaired easily; The insulating coating of outer setting avoids transformer to catch fire in accident, effectively reduces the order of severity of damage sequence, is conducive to increasing the service life.
