Abstract

The present invention relates to a kind of primary more than 3 groups multiply polyurethane enamelled copper wire power transformers.Primary more than 3 groups multiply polyurethane enamelled copper wire power transformers (figure three, four), it is the transformer for providing power supply to compact disc player, Solution codes device, power amplifier and electronic equipment, it includes silicon steel sheet (1) and line bag (2), it is characterized in that the armature winding and secondary windings in line bag all use multiply polyurethane enamelled copper wire coiling, armature winding is divided into more than 3 groups (containing 3 groups) coilings<1>Group,<2 groups>With<3 groups>, each group of secondary alone about between every two groups of primary；Make and insulate of mylar between each winding.The present invention can make equipment in the case where only changing this power transformer without any parts inside Geng Change, and complete equipment performance is raised series, usually catch less than very faint signal reappear.

Description

Primary more than 3 groups multiply polyurethane enamelled copper wire power transformers

Technical field：

The present invention relates to a kind of primary more than 3 groups (containing 3 groups) multiply polyurethane enamelled copper wire power transformer, particularly relate to A kind of and transformer that power supply is provided to compact disc player, Solution codes devices and electronics multiplying arrangement.

Background technology：

《Multiply polyurethane enamelled copper wire power transformer》In, because each secondary windings is all each self-corresponding work electricity Road supply of electrical energy, and their working condition is different, but they are leaning closely against together, will produce each other not Good commissure coupling influence has declined quality index.

The content of the invention：

In view of the above-mentioned problems, it can make between secondary each group that mutually commissure is coupled 3 groups reduced of primary the invention provides a kind of Above multiply polyurethane enamelled copper wire power transformer.The present invention independently isolates each secondary windings using multigroup primary Open, secondary each winding widely different interfering for road that work reduced to minimum, total number of share of stocks of primary more than 3 groups coilings than primary 2 groups around Total number of share of stock of system few 1/3, its performance surmounts the latter with regard to the former.

The object of the present invention is achieved like this：Primary more than 3 groups multiply polyurethane polyurethane enamelled copper wire power supply transformations Device, it includes silicon steel sheet (1) and line bag (2), it is characterised in that armature winding and secondary windings in line bag are all with the poly- ammonia of multiply Ester enamel covered wire coiling, armature winding is divided into more than 3 groups (containing 3 groups) coilings<1>Group,<2>Group and<3>Group, each group time Level is alone about between every two groups of primary.Between each winding insulating barrier is done with three strata ester films.

Claims

1. primary more than 3 groups multiply polyurethane enamel covered wire power transformers, it includes silicon steel sheet (1) and line bag (2), its feature Be that the armature winding in line bag and secondary windings all use multiply polyurethane enamel covered wire coiling, armature winding be divided into 3 groups with Upper the ＞ groups of (containing 3 groups) coiling ＜ 1, the ＞ groups of ＜ 2 and the ＞ groups of ＜ 3, each group of secondary alone about between every two groups of primary；Respectively around Make and insulate of three strata membrane of lipoprotein between group.

2. primary more than 3 groups multiplies polychlorostyrene fat enamel covered wire power transformer according to claim 1, it is characterized in that：Just The polyurethane enamel covered wire coiling of 0.04 millimeter -0.10 millimeter of diameter of level winding, total number of share of stock is more than 200 strands, number of share of stock and effect Fruit is directly proportional.

3. primary more than 3 groups multiplies polychlorostyrene fat enamel covered wire power transformer according to claim 1, it is characterized in that：It is secondary The polyurethane enamel covered wire coiling of 0.04 millimeter -0.5 millimeter of diameter of level winding, total number of share of stock is less than 2000 strands more than 15 strands.

4. primary more than 3 groups multiplies polyurethane enamel covered wire power transformer according to claim 1, it is characterized in that： Each corresponding Same Name of Ends connection of primary all windings is then made a power transformer and used, and it is equal that all windings are divided into group number Or two big combinations not etc., each Same Name of Ends in each big combination are connected and can then turn into an isolating transformer and use.
