Abstract
The utility model relates to a charging machine which can exchange the primary side winding coil number of a rectifying transformer to adjust charging current, mainly comprising the rectifying transformer, a converting switch and a rectifying circuit. A plurality of thread ends are drawn from the primary coil of the rectifying transformer and are adjusted by the converting switch to adjust the working winding numbers of the rectifying transformer, so that the secondary side voltage of the rectifying transformer is changed to adjust the values of the charging current. Owing to the primary side winding current with small winding current and fine size, the taps are easy to produce and simultaneously the electric current of the converting switch at the primary side is only about 5 percent of the secondary side electric current. The converting switch can use a switch with low current to reduce cost and the charging machine is suitable for various standards of batteries for charging.
Description
The utility model is a kind of improved turn-adjusting charging device, and particularly a kind of energy is by the make things convenient for charger of the transposing rectifier transformer primary coil number of turn with the change charging current.
Existing turn-adjusting charging device is to adopt the transposing rectifier transformer secondary coil number of turn, changes voltage and adjusts charging current.This device is rectifier transformer secondary coil tap difficult forming not only, and requires change over switch can bear big electric current, so cost is higher.Often to give the motor vehicle storage battery at some at present, in the field of engine starting storage battery and other charge in batteries, press for a kind of simple in structure, cost is low, reliable operation make things convenient for charger, such charger could be popularized use in charge in batteries.
The purpose of this utility model provide a kind of simple in structure, cost is low, the primary winding-adjusting type of reliable operation makes things convenient for charger, to adapt to the needs of charge in batteries in the every field.
The utility model is achieved in that and makes things convenient for charger by primary winding-adjusting type it is made up of attaching plug, fuse, signal lamp, rectifier transformer, change over switch, rectification circuit, ammeter, storage battery, pump two or two above the end of a thread on the coil on its former limit of rectifier transformer, be connected on respectively on each crossover sub of change over switch.Regulate the working turns that change over switch changes the rectifier transformer primary coil thereby utilize, reach the secondary voltage that changes rectifier transformer, realize regulating the purpose of charging current size.
This charger is because the former limit of rectifier transformer winding current is little, and the line footpath is thin, so the tap coiling is easy, makes simplified manufacturing process.The electric current on former limit has only about 5% of secondary current simultaneously, can use little rheotrope, reaches the purpose that reduces cost.This charger is simple in structure, and reliable operation, cost are low, easy to use, can be used as shop assistant engineer's tool of every motor vehicle indispensability.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 makes things convenient for the circuit theory diagrams of charger for primary winding-adjusting type.
With reference to Fig. 1, primary winding-adjusting type makes things convenient for charger, in the circuit of forming by attaching plug (1), fuse (2), signal lamp (3), rectifier transformer (5), rectification circuit (6), ammeter (7) and storage battery (8), pump two or two above the end of a thread on the primary coil of its rectifier transformer (5), electricity is connected on each crossover sub of a change over switch (4) respectively.The shelves difference that these taps are regulated can determine as required that the number of turn value between the tap makes charging voltage be higher than storage battery (8) rated voltage 10% to 50% scope.When attaching plug (1) when plugging in, adjusting change over switch (4) selects rectifier transformer (5) to go up different former limit taps, its working turns is increased and decreased, cause the secondary voltage lifting of rectifier transformer (5) to change, thereby realize adjusting the purpose of charging current size.Because the electric current on the former limit of rectifier transformer (5) has only about 5% of secondary current, the line footpath that the primary coil winding needs is more much smaller than secondary, so the tapping ratio secondary tap of the former limit of rectifier transformer (5) is much easier, the electric current that while change over switch (4) electricity is connected on former limit has only electricity to be connected on about 5% of secondary current, can use little rheotrope, reduce the purpose of cost thereby reached, and make charger volume-diminished about 50%.The rectification circuit of this machine (6) can adopt bridge rectifier, also can adopt all-wave or half-wave rectifying circuit.The power supply on the former limit of rectifier transformer can be 110 volts or 220 volts or 380 volts of AC power.Can be to the charge in batteries of all size.
Claims (4)
1, a kind of energy is by the make things convenient for charger of the transposing rectifier transformer primary coil number of turn with change alternating current electric current, it is made up of attaching plug (1), fuse (2), signal lamp (3), rectifier transformer (5), rectification circuit (6), ammeter (7) and storage battery (8), it is characterized in that pumping two or two above the end of a thread on the primary coil of rectifier transformer (5), electricity is connected on each crossover sub of change over switch (4) respectively, makes things convenient for charger thereby constitute primary winding-adjusting type.
2, charger according to claim 1 is characterized in that the number of turn value between the tap of rectifier transformer (5) makes charging voltage be higher than storage battery (8) rated voltage 10% to 50% scope.
3, charger according to claim 1 is characterized in that rectification circuit (6) can adopt bridge-type or all-wave or half-wave rectifying circuit.
4, charger according to claim 1 is characterized in that the former limit of rectifier transformer (5) power supply can adopt 110 volts or 220 volts or 380 volts of AC power.
