Relay protection device

The microcomputer relay protection tester is a new type of miniaturized microcomputer relay protection tester developed by referring to the "Technical Conditions for Microcomputer Relay Protection Test Devices (Discussion Draft)" issued by the Ministry of Electric Power, extensively listening to user opinions, summarizing the advantages and disadvantages of similar products in China, and fully utilizing modern microelectronics technology and devices. The microcomputer relay protection tester comes with a large LCD display and a flexible and convenient rotating mouse controller. Single machine independent operation already has strong functionality and can perform most experiments, while connecting to a computer for operation has even greater operational capabilities. Small size and high precision. It has the performance and functions of a large testing instrument, as well as the advantages of a small and flexible testing instrument, easy operation, and high reliability, with a high cost performance ratio. It is a handy tool for relay protection workers.

Product features

1. The standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, which can be easily combined for various types of protection tests. Each phase voltage can output 120V, and the current can output 120A in three parallel. The fourth phase voltage Ux is a multifunctional voltage item, which can be set to four types of 3U0 or detect synchronous voltage, or output any voltage value.

2. Single machine operation is convenient. The single machine can be operated by rotating the mouse conveniently and flexibly through the large LCD screen, with all Chinese displayed. It can complete most of the on-site testing and verification work, verify various relays and microcomputer protections, and simulate complex instantaneous, transient, and conversion faults for whole group testing. Ready to use upon startup, easy and fast to operate.

3. Dual operation mode, connected to a computer and running through the full set of Chinese operating software on the Windows platform, can perform various large-scale, complex, and highly automated verification tasks. It can easily test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.

4. The software function can complete various large-scale complex verification tasks with high automation level, such as three-phase differential test, plant power fast switching, backup automatic switching test, line protection check synchronous reclosing, etc. It can conveniently test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, online printing reports, etc.

5. The switch quantity contact rich relay protection tester has 8 contact inputs and 4 pairs of empty contact outputs. The input contacts are compatible with empty contacts and 0-250V potential contacts, and can be intelligently and automatically recognized. The input and output contacts can be expanded according to user needs.

6UHV-702 microcomputer relay protection deviceThere is a large LCD display screen. This machine adopts a 320 × 240 dot matrix large screen high-resolution graphic LCD display screen. All operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, with intuitive and clear display.

7. Self protection adopts a reasonably designed heat dissipation structure, with reliable multiple protection measures and power soft start, as well as certain fault self diagnosis and locking functions.

8. There is an independent dedicated DC power output device with one 110V and 220V dedicated adjustable DC power output.

9. High cost-effectiveness belongs to cross disciplinary joint design products, which integrate multiple professional technological achievements. Combining the performance of a large testing instrument with the price of a small testing instrument, it has a high cost performance ratio.
