The standard output of 4 phases of voltage and 3 phases of current
It could combine various type of current or voltage conveniently and has diversity type of protective experiment. Every phase of voltage output is 120V and the total of the parallel current is 120A. The fourth phase voltage Ux has many functions and it can be set to be 4 type of every three voltages or synchronism checking voltage or output any value of voltage.
Product Characteristics
1. Standard 4-phase voltage and 3-phase current output with 4-phase voltage and 3-phase current output can conveniently carry out various combination outputs for various types of protection tests. Single-phase voltage can output up to 120V single-phase current up to 40A (10 seconds) current three and can output up to 120A the fourth phase voltage Ux is a multi-function voltage item can be set as 4 kinds of 3U0 or check the same period voltage or a certain voltage value of the case output.
2. Single machine is easy to operate. The single machine is operated by a convenient and flexible rotating mouse through a large LCD screen all of which are displayed in Chinese. It can complete most of the field test verification work can verify all kinds of relays and microcomputer protection and can simulate all kinds of complex transient permanent and transformational faults for the whole group of tests. Boot can be used easy to operate.
3. Double operation mode connected to the computer operation through the Windows platform of the full set of Chinese operating software can carry out a variety of large complex and higher degree of automation verification work can be easily tested and scanned a variety of protection fixed value can be real-time storage test data display vector diagram draw fault waveform online print report etc.
4. Software is so powerful that can complete all kinds of high degree of automation of large complex check work such as three phase differential test auxiliary power fast cutting prepared from the cast test line protection inspection period reclosing etc. can easily test and scanning protection setting various fault playback real-time storage test data show that the vector diagram online printing report etc.
5. Switch quantity contact is rich three - phase for 7 contact input and 2 pairs of empty contact output. The input contacts are compatible with 0 ~ 250V potential contacts and can be identified automatically. Input and output contacts can be expanded according to user needs.
6. Large screen LCD display microcomputer relay protection tester adopts 320×240 lattice large screen high-resolution graphics LCD display all the operation process are set on the display screen the operation interface and test results are displayed in Chinese the display is intuitive and clear.
7. Self-protection adopt reasonable design of heat dissipation structure and have a variety of reliable and perfect protection measures and power soft start and a certain fault self-diagnosis and locking function.
8. With an independent dedicated dc power output the device is equipped with one 110V and 220V dedicated dc power output.
9. High cost performance belongs to the cross - professional joint design products integrated multi - professional advanced scientific and technological achievements. Both large tester performance and small tester price with a high performance ratio.
