Description
Technical Field
The utility model belongs to the technical field of withstand voltage tester, specifically indicate a withstand voltage tester system of function is examined to area point.
Background
According to the regulation of the withstand voltage tester verification regulation (JJG 795-2016), the withstand voltage verification cycle is one year, but if the withstand voltage tester fails to be found timely in daily use, potential safety hazards are brought to a tested product, and when a plurality of customers carry out daily point detection on the withstand voltage current tester, a voltage is applied to an external point detection device to see whether the current of the tester meets the technical requirements, so that a professional is required to operate.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a withstand voltage tester system that start is examined by oneself.
In order to realize the above functions, the utility model discloses the technical scheme who takes as follows: the utility model provides a withstand voltage tester system of function is examined to area point, includes singlechip, AD module, high voltage relay, point and examines sampling, voltage follower, wave detector and signal adjustment module, the AD module links to each other with the singlechip, high voltage relay links to each other with the singlechip, the point is examined the sampling and is linked to each other with high voltage relay, voltage follower links to each other with the wave detector, the wave detector links to each other with signal adjustment module, signal adjustment module links to each other with the AD module, the point is examined the sampling and is linked to each other with voltage follower.
Furthermore, a sampling resistor is arranged at the point inspection sampling position.
The utility model adopts the above structure to gain beneficial effect as follows: the utility model provides a pair of withstand voltage tester system of function is examined to area point easy operation, the electric current of point inspection passageway gives the AD module after the signal adjustment module again behind the wave detector behind the voltage follower again, again behind the AD module conversion through the singlechip calculation current value accord with technical requirement, if accord with the automatic test channel of getting back to of requirement instrument, be not conform to and send the chimes of doom, pass through the PC on the instrument serial ports with the self-checking result simultaneously, the chimes of doom can press the instrument button that resets and clear away.
Drawings
Fig. 1 is a circuit diagram of the voltage withstanding tester system with a point inspection function of the present invention.
The device comprises a single chip microcomputer 1, a single-chip microcomputer 2, an AD module 3, a high-voltage relay 4, a point inspection sampling module 5, a voltage follower 6, a wave detector 7, a signal adjusting module 8 and a sampling resistor.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The present invention will be described in further detail with reference to the accompanying drawings.
As fig. 1, the utility model relates to a withstand voltage tester system of function is examined to area point, examine sampling 4, voltage follower 5, wave detector 6 and signal adjustment module 7 including singlechip 1, AD module 2, high-voltage relay 3, point, AD module 2 links to each other with singlechip 1, high-voltage relay 3 links to each other with singlechip 1, the point is examined sampling 4 and is linked to each other with high-voltage relay 3, voltage follower 5 links to each other with wave detector 6, wave detector 6 links to each other with signal adjustment module 7, signal adjustment module 7 links to each other with AD module 2, the point is examined sampling 4 and is linked to each other with voltage follower 5.
And a sampling resistor 8 is arranged at the point inspection sampling 4.
As shown in the figure, the range of the single chip program curing point inspection is as follows: the point detection voltage is 1500V, and the load sampling resistance R1 of the point detection channel is 500K, so the point detection current is 1500/500=3 mA; when the instrument is started, the single chip microcomputer controls the JTX to be in a point inspection channel, 1500V voltage is applied to a resistor of 500K Ω, a sampling resistor of point inspection current is 5 Ω, the current of the point inspection channel passes through a voltage follower, a detector and a signal adjusting module and then is transmitted to an AD module, the AD module is converted and then the single chip microcomputer calculates whether the current value meets the technical requirements, if the current value meets the requirements, the instrument automatically returns to the test channel, the alarm sound is not sent out, meanwhile, the self-inspection result is uploaded to a PC through an instrument serial port, and the alarm sound can be cleared according to an instrument reset key.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
