Abstract
Disclosed is a novel temperature control ring transformer, which relates to the transformer technical field. The transformer comprises a coil winding and a terminal, wherein the coil winding is composed of enameled wires winding an iron core, the coil winding includes a primary winding and secondary windings, the iron core is ring-shaped, a normally closed temperature controlled switch is arranged in a circuit of the primary winding in a series connection mode, and the outer surface of the normally closed temperature controlled switch is contacted with the outer surface of the coil winding in an insulation mode. The novel temperature control ring transformer has the advantages of being simple in structure, convenient to manufacture and mount, small in size and no-load loss, low in temperature rising, small in noise and magnetic leakage, and low in price, and the service life can achieve more than 10 years. And as the power range of the transformer is between 100 VA and 1200 VA, the transformer is applicable in areas such as various low voltage control cabinets, decorative lighting power sources, audio equipment and the like.
Description
Technical field
The present invention relates to the transformer technology field, be specifically related to a kind of novel temperature control toroidal transformer.
Background technology
Transformer is made up of iron core, coil, structural member three parts; Toroidal transformer adopts annular core; Because interface is few; Rolling direction at steel band forms flux, and its loss or exciting curent are little, therefore is widely used in general power distribution transformer and sound equipment loudspeaker and precision instrument aspect.But traditional toroidal transformer is not established temperature detect switch (TDS), thereby when temperature is too high, causes more serious damage easily.
Summary of the invention
The purpose of this invention is to provide a kind of novel temperature control toroidal transformer, it is simple in structure, fabrication and installation are convenient, volume is little, no-load loss is little, temperature rise is low, noise is little, leakage field is little, low price, long service life.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: it comprises coil windings, the terminals of being made up of the enamelled wire Wound core; Said coil windings is divided into elementary winding and secondary winding; Said iron core is a ring-type shape, the normally closed temperature detect switch (TDS) of series connection in the circuit of said elementary winding, and the outer surface of said normally closed temperature detect switch (TDS) contacts with the insulation of the outer surface of said coil windings.
Said normally closed temperature detect switch (TDS) is 90 ℃ to 120 ℃ a normally closed temperature detect switch (TDS).
Said iron core is not for cutting iron core, and its radial section is a rectangle.
Said secondary winding is 3 to 5 groups.
Be provided with ground path in the said coil windings.
Said terminals and conducting metal welding or riveted joint are inserted in the binding post; And its terminals adopt plastic material to process.
The present invention is simple in structure, fabrication and installation are convenient, volume is little, no-load loss is little, temperature rise is low, noise is little, leakage field is little, low price, useful life can reach more than 10 years; Its power bracket is 100-1200VA, is applicable to fields such as all kinds of low-voltage power distributing cabinets, lamp decoration power supply, sound appliances.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of coil windings among the present invention.
Embodiment
With reference to Fig. 1-Fig. 2; This embodiment adopts following technical scheme: it comprises coil windings 2, the terminals of being made up of enamelled wire Wound core 13; Said coil windings 2 is divided into elementary winding 4 and secondary winding 5; Said iron core 1 is a ring-type shape, the normally closed temperature detect switch (TDS) 6 of series connection in the circuit of said elementary winding 4, and the outer surface of said normally closed temperature detect switch (TDS) 6 contacts with the outer surface insulation of said coil windings 2.
Said normally closed temperature detect switch (TDS) 6 is 90 ℃ to 120 ℃ a normally closed temperature detect switch (TDS).
Said iron core 1 is not for cutting iron core, and its radial section is a rectangle.
Said secondary winding 5 is 3 groups.
Be provided with ground path 7 in the said coil windings 2.
Said terminals 3 and conducting metal welding or riveted joint insert in the binding post; And its terminals 3 adopt plastic material to process.
Work as transformer in this embodiment and work long hours, coil temperature rises to set point, normally closed temperature detect switch (TDS) 6 automatic disconnections; After temperature descended, its normally closed temperature detect switch (TDS) 6 is auto-closing again, thereby can avoid occurring owing to temperature is too high the phenomenon of accidental injury.
This embodiment is simple in structure, fabrication and installation are convenient, volume is little, no-load loss is little, temperature rise is low, noise is little, leakage field is little, low price, useful life can reach more than 10 years; Its power bracket is 100-1200VA, is applicable to fields such as all kinds of low-voltage power distributing cabinets, lamp decoration power supply, sound appliances.
