What is the high voltage switch tester used for

time:2021/10/30   source:华天电力  reading:671 time

The high-voltage switch tester can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers with various voltage levels, such as less oil, more oil, vacuum, and sulfur hexafluoride. The anti-interference ability is strong, even when the bypass bus of the 500KV substation is live, it can be easily tested and the measurement is accurate.


General-purpose speed sensor (optional), linear linear sensor, rotary sensor, installation is extremely convenient and simple. Switch action once, get all the data of the switch mechanical characteristic test and the corresponding waveform atlas.

The host can store field test data, and the real-time clock inside the machine is convenient for archiving and saving test date and time. The main unit has a large screen, wide temperature, straight perspective, background light LCD, full Chinese display of all data and maps, LCD contrast electronic adjustment, power-off memory.


Chinese menu operation, easy to use. The built-in printer of the instrument can quickly print all data and graphs at any time. The instrument is equipped with a USB interface and data analysis management software, which can be operated online with a PC. The test results can be directly stored in a U disk, and can also be output to various needle, laser or inkjet printers to print test reports to computerize the field test.


Definition of Terms:


Opening (closing) time: The opening (closing) coil is energized as the starting point for timing, and the time to the opening (closing) of the moving and static contacts.


Same period: In the same phase, the difference between the maximum and minimum opening (closing) time.


Phase-to-phase synchronization: Among the three phases, the difference between the largest and smallest opening (closing) time.


Average speed: In the process of opening (closing), 10% of the front and back of the total stroke of the moving contact are removed, and the middle 80% is taken as the ratio of the stroke of the moving contact to the time.


Maximum speed: During the opening (closing) process, after the moving contact starts to move, the movement of the moving contact is a speed unit every 10ms until the moving contact stops, and several speed unit values are obtained, of which the largest unit speed The value is the maximum speed of opening (closing).


Just opening (closing) speed: According to the different manufacturers of the tested switch and different switch models, each manufacturer defines different just opening and closing speeds. This tester includes various definitions for users Choose for yourself.
