The utility model discloses a high frequency intelligent charger, which comprises a shell 11, an input power supply socket 10, an output terminal 4, a power supply indicating light 2, a charging indicating light 1, a starting button 3, a radiating fan 6, a power supply switch 8, an input main fuse 7, an input branching fuse 9, an output fuse 5, an output aviation plug 13, an output power supply wire 14, a charging clamp 12, a current control circuit, a voltage-stabilizing circuit, an anode and cathode automatic distinguishing and replacing circuit and an electronic element. In the circuit, an anode and a cathode of a storage battery pole can be automatically distinguished due to the automatic distinguishing function, an output end has no need to distinguish the anode and the cathode, the charging clamp is in an electricity-free state before connecting with the storage battery pole, and thus the phenomenon of short circuit of two charging clamps and misconnection of the positive and the negative electrodes are avoided.
Description
One, technical field
The utility model relates to a kind of charger that does not have both positive and negative polarity, especially a kind of high frequency intelligent charging machine of storage battery charging of ground observation, Di Kuang, communication, climate monitoring instrument and the place vehicle that is applicable to the variation of ambient temperature impermanence.
Two, background technology
At present, the charger kind is a lot, though can satisfy the charging of various performance storage batterys, the charger dc output end does not have also not have on the charger market of branch of both positive and negative polarity.
The purpose of this utility model is to use the high frequency intelligent charging machine of the seismic prospecting instrument in field with the storage battery charging at present storage battery, and the common charger of present open-air usefulness generally can not solve the series connection of polylith storage battery and surpass the risk that charger that safe voltage, short circuit sparking, both positive and negative polarity misconnection cause and storage battery damage and get an electric shock.The utility model provides a kind of sparking that can cause from preventing misconnection in essence, stops between two charging folders short circuit and burns the high frequency intelligent charging machine of the accident of charger.
Three, utility model content
High frequency intelligent charging machine described in the utility model comprises: comprise shell 11, input outlet 10, lead-out terminal 4, power supply indicator 2, charging indicator light 1, start button 3, cooling fan 6, mains switch 8, the total insurance 7 of input, input insures 9, export insurance 5 along separate routes, output aviation plug 13, out-put supply line 14, charging folder 12, and current control circuit, constant voltage circuit and both positive and negative polarity are discerned permutation circuit (Fig. 4) automatically, electronic devices and components (Fig. 4).The high frequency intelligent charging machine is by the combined running of electronic devices and components and several partial circuits.
This high frequency intelligent charging machine has following function:
The both positive and negative polarity of this charger is discerned permutation circuit automatically, its principle is to utilize the characteristic of the unidirectional conducting of diode that the both positive and negative polarity of storage battery is discerned, utilize the function of relay to realize discerning automatically the both positive and negative polarity of storage battery pole then, automatically press the charging of storage battery polarity then, therefore the branch that does not have both positive and negative polarity is pressed from both sides in two of output chargings, can be connected with the storage battery pole arbitrarily.
This charger has six charhing units, can be simultaneously to six storage battery chargings.Each unit works alone, and breaking down if any indivedual charhing units does not influence other charhing unit operate as normal.Wherein two of each unit chargings are in electroless state before being clipped in and being connected with the storage battery pole, do not have the short circuit spark phenomenon.And if the charging of each unit be clipped in contact with storage battery before mistake press charge button, output still is in electroless state.In charging process, stop if desired charging or loose contact or two charging folder any one when separating with storage battery, the DC power supply that charger can automatic disconnection output, two charging folders all are in electroless state.
The signal that this high frequency intelligent charging machine changes battery voltage by current control circuit becomes digital signal voltage along with the degree of saturation storage battery of storage battery in charging process and can raise gradually, the signal that changes is delivered to induction coil and realizes the size of change electric current automatically by induced signal, and the automatic disconnection function is arranged after storage battery is saturated.Charger can be reduced to 30% of rated current automatically when storage battery reaches 85% saturation, because current control circuit can be realized the function that decays gradually along with the saturated degree charging current of storage battery, in charging process, along with the battery voltage charging current that raises gradually then is gradually the trend that reduces, it is fully saturated that storage battery is obtained, compare the possibility of having avoided storage battery blast in empty saturated phenomenon of storage battery and the charging process with traditional constant current charger, can improve the discharge time of storage battery and the useful life of storage battery.
The constant voltage circuit of high frequency intelligent charging machine changes resistance by light idol resistance, when the high time-frequency band of importing of alternating voltage narrows down, broaden when the voltage of importing hangs down time-frequency band, thereby the variation of the width of frequency band changes the purpose that resistance realizes automatic regulation voltage by light idol resistance.When input voltage (electric main) fluctuates between 170V-250V to the rated voltage of high frequency intelligent charging machine output (14,5v) and initial current (20A) without any influence, need not to dispose voltage regulator and manual adjustments input voltage.Because the intellectuality of charger, constant voltage circuit can realize the self-regulating effect of voltage, (civil power) power supply rated voltage (220V) is not strict with, between 170v-250v, do not influence the DC charging voltage of output, when supply power voltage (civil power) is unstable, do not need the manual adjustment input voltage, so this charger is particularly useful for to the unsettled area of (civil power) supply power voltage.
Because the high frequency intelligent charging machine has taken into full account on components and parts are matched the working temperature function of joint is automatically arranged on the requirement of high low temperature and the circuit design, so can under-40 ° to 70 ° temperature environment, keep operate as normal, its cooling fan starts and stops fan running automatically according to working temperature, and because can realizing storage battery, this charger closes the function of out-put supply automatically after saturated, so the workman scene that need not to charge is on duty.
