Abstract

The utility model discloses a ring-shaped energy-saving rectification charger, comprising a transformer, a control switch and a bridge type rectifier, and the transformer is a ring-shaped transformer, and a permanent iron core in the transformer is a hollow cylinder and is winded with coils, and a plurality of middle taps are arranged in the primary and the secondary of the transformer which are provided with conversion switches. The utility model is high in efficiency, low in loss, small in magnetic leakage, strong in overload ability and low in noise, which has the function of energy saving; the utility model is steady in quality, long in service life, reliable in safety coefficient, convenient in operation, and only a power wire is needed to be plugged directly into 220V electric net, and a plurality of voltage gears on the charger panel are supplied for the reasonable choice of users, and the current has multi-gears to regulate, and the utility model has steady charging current and is strong in anti-interference ability.

Description

The energy-conservation rectification charging machine of annular

Technical field

The utility model relates to a kind of rectification charging machine, relates in particular to the energy-conservation rectification charging machine of a kind of annular.

Background technology

The existing defective of present employed KGCA controllable silicon series charger has: (1) power factor is low, and loss is big, and very high to the overload capacity requirement of electrical network, otherwise will influence the normal use of whole piece circuit; (2) coefficient of safety instability, the 220V electrical network enters in the machine, and wherein a power line directly is a utmost point of charge power supply without any safety and quarantine measures, reader ground misconnection during as if charging, then the high-tension electricity netting twine is directly to storage battery, touches storage battery this moment and will cause the danger of getting an electric shock; (3) stability is poor, and in the charging course of work, charging current increases through regular meeting, and thyristor is difficult to control the size of its electric current as being operated under low-voltage, the large current charge situation, finally causes element breakdown.

Summary of the invention

The purpose of this utility model is: a kind of above-mentioned defective efficient of prior art height that overcomes is provided, and loss is low, and leakage field is little, and overload capacity is strong, and noise is low, has the rectification charging machine of energy-conservation effect.

The utility model is realized by following scheme: be made up of transformer, control switch, bridge rectifier, its transformer is a toroidal transformer, permanent magnetism iron core in the transformer is a hollow cylinder, coiling on it, and elementary and secondary a plurality of centre taps, the elementary and secondary change over switch that is equipped with of being equipped with of transformer.

Structure of the present utility model and principle, performance, the effect each side has following superior part than the serial charger of KGCA controllable silicon: (1) transformer adopting high-quality annular core, its efficient height, loss is low, and leakage field is little, overload capacity is strong, and noise is low, has energy-conservation effect; (2) steady quality, long service life; (3) coefficient of safety is reliable, and the 220V electrical network reduces through transformer isolation, obtains one group of low-voltage, power supply bottle charging after rectification is direct voltage again, thus avoided the 220V electrical network directly to enter the Danger Electric shock risk of storage battery; (4) easy to operate, only need power line is directly inserted the 220V electrical network, have on the charger panel and respectively organize voltage gear for user's choose reasonable, electric current has many gears adjustable; (5) show that accurately direct voltage, electric current all adopt the higher instrument of accuracy; (6) charging current is stable, and antijamming capability is strong, is not subjected to the influence of electrical network, and along with capacity increase and the prolongation of time to the storage battery charging, charging current descends gradually.

Description of drawings

Accompanying drawing is the utility model circuit theory diagrams.

Embodiment

The utility model is made up of fuse RD, transformer B, control switch K, bridge rectifier D 1-D4, ammeter A, voltmeter V, fuse RD, control switch K are connected to the elementary two ends of transformer B, bridge rectifier D 1-D4 connects B level of transformer, transformer B is a toroidal transformer, its permanent magnetism iron core is a hollow cylinder, enclosing coiling by a plurality of silicon steel sheets one forms, it is elementary and secondary to be equipped with a plurality of centre taps, be provided with change over switch K1, K2 simultaneously, in order to select to be connected to elementary, secondary each tap, realize the conversion of voltage gear respectively.Go back end span in its power supply input and be connected to work light.

Transformer annular core structure of the present utility model can to turn to internal diameter be that 40 millimeters, external diameter are that 170 millimeters, height are 85 millimeters hollow cylinder in order to be enclosed by thick 0.35 millimeter, high 80 millimeters silicon steel sheet one.

Operation principle of the present utility model is: 220V alternating current zero line enters primary behind fuse, and phase line arrives primary gear place through power control switch.The secondary coil tap directly enters in the bridge rectifier of being made up of 4 diodes, as the power supply of bridge rectifier,, become direct voltage after the bridge rectifier rectification by the transformer step-down, by ammeter, voltmeter, to observe the size of charging current and voltage.
