Abstract
The utility model relates to a voltage adjusting device for increasing and lowering electric voltage, which is used for increasing and lowering electric voltage of various electric apparatuses. The utility model is characterized in that a cylinder-shaped iron core wound with coils forms an oblate cylinder shape. The number of turns of the coils wound on the iron core is more than 416 turns. The scope of voltage increase is more than 250V. A casing of the utility model is also provided with a voltmeter and a high and low pressure alarm. The utility model can increase the scope of voltage increase. The utility model increases the service life of various electrical equipment, and meets need of various electric apparatus users. The utility model has simple structure, low cost and easy use. The utility model is a novel voltage adjusting device for increasing and lowering electric voltage.
Description
The utility model relates to a kind of Voltage adjusting device, is used for the ascending, descending voltage of various electrical equipment, belongs to electrical installation.
The no-load voltage ratio of used voltage regulator is 1.15 in the market, so the accent voltage range is 0-250V, therefore can only be used for falling end voltage.In the existing power shortage of China, be not suitable for various users' demand under the generally low situation of voltage, make its various power consumption equipment cisco unity malfunctions and running, influence the useful life of equipment.
The purpose of this utility model is the above Voltage adjusting device of 250V in order to overcome above-mentioned deficiency and a kind of scope of boosting is provided.
To achieve these goals, concrete technical scheme of the present utility model is: comprise the chassis, be tied with iron core, regulating shaft, sliding contact, terminal board, reading dial, the shell of coil, the garden tubbiness iron core that is tied with coil is that flat garden is barrel-shaped, number of turn of institute's kinking circle is more than 416 circles on it, the scope of boosting is equipped with the voltmeter in parallel with the output on the terminal board, high-low pressure alarm on the shell of voltage regulator more than 250V.
The utility model has the advantages that: existing voltage regulator is improved, has improved the scope of boosting of voltage regulator greatly, satisfied vast electrical equipment user's needs the useful life of having improved various electric equipments, simple in structure, cost is low, easy to use, be easy to promote.
Concrete structure of the present utility model is provided by accompanying drawing 1,2.
Fig. 1 is a Voltage adjusting device overall structure schematic diagram.
Fig. 2 is the circuit diagram of Voltage adjusting device.
Primary structure is among the figure: chassis 1, coil 2, iron core 3, regulating shaft 4, sliding contact 5, terminal board 6, reading dial 7, shell 8, output 9, input 10, voltmeter 11, high-low pressure alarm 12.
Below in conjunction with accompanying drawing the utility model is described in detail.
This Voltage adjusting device, comprise chassis 1, be tied with the iron core 3 of coil 2, regulating shaft 4, sliding contact 5, terminal board 6, reading dial 7 and shell 8, shell is housed on the chassis, dress iron core in the shell, the garden tubbiness iron core that is tied with coil is that flat garden is barrel-shaped, number of turn of institute's kinking circle is more than 416 circles on it, the scope of boosting is more than 250V, debug nodal axisn in the iron core, regulating shaft links to each other with sliding contact, regulating shaft drives sliding contact and slides along the coil surface, thereby the coil turn position that slides into required output voltage values obtains required voltage, this moment, voltmeter was pointed out output voltage, the regulating shaft top links to each other with reading dial, and shown voltage digital is the virtual voltage of user's institute's electrical appliance and voltage regulator itself on the reading dial, connects input and output on the terminal board, input termination 220V power supply, be equipped with on the shell of voltage regulator with terminal board on the voltmeter 11 that joins of output 9, high, low pressure alarm 12.When using rated voltage as the 220V situation under, when rated voltage was lower than 220V, virtual voltage can be measured by voltmeter, rotated handle on the reading dial according to user's use needs again and the reading of voltmeter is transferred to required voltage got final product.
