Abstract
The invention discloses a power capacitor for a charger. The power capacitor for the charger comprises four or more capacitors sets, wherein one terminal of each capacitor set is electrically connected with a binding post on a shell of the power capacitor for the charger, the otherbinding posts of all the capacitor sets are connected and then electrically connected with a wiring terminal on the shell of the power capacitor for the charger through a lead, discharge resistors are connected to the two ends of each capacitor set in parallel, and all the capacitors and the discharge resistors are packaged in the shell.
Description
Technical field
The invention belongs to power capacitor field, be specifically related to a kind of charger Power Capacitors.
Background technology
Power capacitor is to be widely used in electric power system, and power system reactive power, improves power factor of electric network by way of compensation, reduces the loss of voltage, improves a kind of device of electrical network transmission of electric energy power.What China's electrical network was carried is three phase sine alternating current, the power capacitor using, is generally single-phase electricity container and three-phase capacitor, and single-phase electricity has two terminals, can as required the identical capacitor of three pool-sizes be connected into star or dihedral, be applied in three-phase circuit.Three-phase power capacitor, is that the identical capacitor of three pool-sizes is connected into dihedral or star and is packaged into after one, draws three terminals, is arranged on three phase mains electrical network is carried out to reactive power compensation.
With the charger of capacitor step-down current stabilization, there is automatic adaptation battery voltage charging, energy-efficient, allow short circuit operation, in the time of charging, can also to electrical network, carry out the features such as reactive power compensation, apply more and more general.When to charge in batteries, charge mode has dividing of initial charge and daily charging, initial charge and daily charging have again dividing of first stage charging, second stage charging, phase III charging, the charging current of each charge mode, charging stage requirement is different, just needs the capacitance of adjusting input to obtain different charging currents.So just require the electric capacity dropping at least will have more than four groups or four groups, obviously, the power capacitor that reactive power compensation is used, only have three group capacitors, and fixing star-star connection or angle scheme in inside, have been connected into, capacity regulating is inconvenient, is difficult to meet the needs that charger regulates capacitance.Although also can combine and be met charger about the needs of capacity regulating by single discrete capacitor, discrete component wiring is complicated, installs inconvenient.
Summary of the invention
The object of this invention is to provide a kind of charger Power Capacitors, described charger Power Capacitors comprises at least four groups or more than four groups capacitor groups, terminals of every group capacitor are electrically connected to by the binding post on lead-in wire and described charger Power Capacitors shell, after all linking together, another terminals of every group capacitor are electrically connected to the equal parallel discharge resistance in every group capacitor group two ends by the binding post on lead-in wire and described charger Power Capacitors shell.The capacity of the every group capacitor in described charger Power Capacitors requires to determine according to the charging current of concrete storage battery, can be completely equal, also can be completely unequal, also can other group or several groups equate, remaining several groups or one group unequal.Every group of discharge resistance that electric capacity configures, the capacity of its power and resistance value and institute's adapted capacitor group adapts.Described a kind of charger Power Capacitors, all capacitors and discharge resistance, lead-in wire are all encapsulated in a shell, leaded respectively with casing cover on binding post be electrically connected to.
Accompanying drawing explanation
Accompanying drawing is the key wiring diagram of a kind of charger Power Capacitors of the present invention.

Below in conjunction with accompanying drawing, embodiments of the invention are described, by embodiment, the present invention may be better understood, and this embodiment is use for illustrative purposes only, and be not construed as limiting the invention.
The technical scheme of a kind of charger Power Capacitors of the present invention is to form like this, the Power Capacitors of charger shown in accompanying drawing comprises four group capacitor group C1, C2, C3, C4, terminals of capacitor group C1 are electrically connected to by the binding post 1 on lead-in wire and described charger Power Capacitors shell, terminals of capacitor group C2 are electrically connected to by the binding post 2 on lead-in wire and described charger Power Capacitors shell, terminals of capacitor group C3 are electrically connected to by the binding post 3 on lead-in wire and described charger Power Capacitors shell, terminals of capacitor group C4 are electrically connected to by the binding post 4 on lead-in wire and described charger Power Capacitors shell, after all linking together, another terminals of every group capacitor are electrically connected to by the binding post 5 on lead-in wire and described charger Power Capacitors shell, capacitor group C1, C2, C3, the equal parallel discharge resistance R 1 in C4 two ends, R2, R3, R4.The capacity of every group capacitor group C1 in described charger Power Capacitors, C2, C3, C4 requires to determine according to the charging current of concrete storage battery, can be completely equal, also can be completely unequal, also can other group or several groups equate, remaining several groups or one group unequal.Every group of discharge resistance R1, R2, R3, R4 that electric capacity configures, the capacity of its power and resistance value and institute's adapted capacitor group adapts.Described a kind of charger Power Capacitors, all capacitor groups and discharge resistance, lead-in wire are all encapsulated in a shell, leaded respectively with casing cover on binding post 1,2,3,4,5 be electrically connected to.
The shell of a kind of charger Power Capacitors of the present invention, capacitor core, end cap, binding post, filler, insulation etc., by existing provincial standard, industry standard, national standard and company standard manufacture.
Obviously, a kind of charger Power Capacitors of the present invention is not only applicable to the charger of single phase poaer supply and three phase mains, equally can be used as the use of the reactive power compensation of single phase alternating current power supply and three-phase alternating-current supply yet.
