Abstract
The invention discloses a charger of an energy-saving electric vehicle and relates to control over a transformer winding structure for the charger of the energy-saving electric vehicle and charging temperature. The charger comprises a transformer winding and a temperature control device, wherein the transformer winding comprises a magnetic core, and a primary winding and a secondary winding which are coiled on the magnetic core; the primary winding and the secondary winding are separated from each other by using an insulation layer and are formed by coiling by copper foils and covering the copper foils with insulation layers; the temperature control device comprises a temperature acquisition device which is used for transmitting an acquired temperature signal to a controller, and by comparing the temperature signal with a preset signal preset in the controller, a fan and a motor are controlled to work. The invention also provides an energy-saving electric vehicle which is good in electric performance and saves energy and of which the charger is long in service life.
Description
Technical field
The present invention relates to a kind of energy-saving electric automobile charger, relate to specifically of the control of energy-saving electric automobile charger with transformer winding structure and charging temperature.
Background technology
The Transformer Winding of traditional electric automobile charger mostly adopts the copper cash coiling to form, and there is following defective in this kind winding construction: 1) kelvin effect is obvious, has increased energy consumption; 2) heat dispersion of copper cash is not good, influences the useful life and the energy consumption of transformer; 3) the easy oxidation of copper cash can influence its electric property.
For the heat dissipation problem that addresses the above problem, generally be provided with fan in the charger now, utilize and air-cooled charger is dispelled the heat.But when charger just charges, because caloric value is also little, there is no need consume electric power and open fan, but the fan of charger inside is in the charger charging now, fan is also worked thereupon, and this has just caused the unnecessary consumption of electric energy; Simultaneously fan damages or the air port accident is stopped, heat dispersion descends, and this moment, the charger internal temperature can not get timely heat radiation, after the temperature of charger surpasses uniform temperature, as untimely cutting off the electricity supply, will cause the damage of charger even causes the accident.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose be to provide a kind of good electric property, energy-conservation, long service life the energy-saving electric automobile.
Technical scheme of the present invention is: transformer winding structure of the present invention comprises magnetic core and elementary winding and the secondary winding on magnetic core around the home, be separated by with insulating barrier between elementary winding and the secondary winding, elementary winding and secondary group are by the Copper Foil coiling and be arranged on the outer insulating barrier of Copper Foil and form, and turn-to-turn is established insulating barrier in the Copper Foil; The present invention also comprises temperature collecting device, and temperature collecting device will collect to such an extent that temperature signal sends controller to, by with controller in default preset signals relatively control fan work and machine operation.
Advantage of the present invention is: 1) adopt Copper Foil, the kelvin effect of Copper Foil reduces than copper cash is obvious, has energy-conservation effect, and the present invention adopts Copper Foil, has extraordinary electric property; 2) further, the present invention can adopt Copper Foil, and it is compared with the copper conductor of identical D.C. resistance, has the following advantages: 2.1: in the single conductor, electric current exists through copper foil surface; And Copper Foil does not all have the copper cash sensitivity to kelvin effect and proximity effect, Copper Foil can make the conductor total surface increase some simultaneously, therefore it is long-pending also to have increased surface of conductors, improved the radiating condition of cable, increased area of dissipation, under equal material cost condition, surface area increases can effectively reduce long-pending skin effect, and it is much economical that the index of AC resistance is wanted.2.2 have good anti-corrosion: copper line surface contacts with air, after finishing, coiling needs dipping lacquer, increase surface insulation layer, in case oxidation and corrosion, particularly in the coastal area, the chloride ion that salt fog contained in the atmosphere can condense upon the surface of bare copper wire, easily impurity and the defective on the surface causes local corrosion on every side, form hole, crackle and micro cell, the corrosion of aggravation copper conductors, Copper Foil then improves greatly in the corrosion-resistant performance of saying.2.3: good weldability: Copper Foil is a fine copper, therefore has with the same solderability of pure copper wire, convenient production.
According to above analysis, adopt Copper Foil, have good energy-saving effect, excellent radiation performance, can improve the useful life of charger.
The present invention includes the secondary temperature control equipment simultaneously: 1) fan control device: when temperature during less than design temperature, fan quits work, and has reduced the consumption of electric energy, and when temperature was higher than uniform temperature, fan work improved the heat dispersion of charger; 2) charger overtemperture control device: when temperature is higher than the highest alarm temperature of charger, cut off charge power supply automatically, to guarantee the safe handling of charger.So further the present invention has energy-conservation effect, also has the advantage that improves the charger coefficient of safety simultaneously.

Embodiment
Transformer winding structure of the present invention comprises magnetic core 1 and elementary winding 4 on magnetic core 1 and secondary winding 2 around the home, be separated by with insulating barrier 3 between elementary winding 4 and the secondary winding 2, elementary winding 4 and secondary winding 2 are by Copper Foil and be arranged on the outer insulating barrier composition of Copper Foil, and copper conductor of the present invention is a Copper Foil.
The present invention includes temperature collecting device, temperature collecting device will collect to such an extent that temperature signal sends controller to, by with controller in default preset signals relatively control fan work and machine operation.
The course of work of the present invention is: temperature collecting device will collect to such an extent that temperature signal is sent to controller, then with controller in default preset signals relatively, when temperature is lower than certain temperature, fan quits work, otherwise fan work, when the charger temperature is higher than charger during high alarm temperature, then cut off the electricity supply.
The present invention can be provided with warning device, makes mutually deserved measure with reminds people according to corresponding situation.
