Relay protection tester

Section One Main Features

standard4-phase voltage and 3-phase current output have4-phase voltage and 3-phase current output can be easily combined for various types of protection tests. Each phase voltage can output120VCan output three currents in parallel120A， 第The 4-phase voltage Ux is a multifunctional voltage item that can be set to 4 types of 3U0Or check the voltage during the same period，Or output in the case of any voltage value.

Convenient standalone operation Single machine is convenient and flexiblePhotoelectric trackballThe mouse is operated through a large LCD screen, displaying all Chinese characters. It can complete most of the on-site testing and verification work, verify various relays and microcomputer protections, and simulate complex instantaneous, permanent, and conversion faults for whole group testing. Ready to use upon startup, easy and fast to operate.

Dual operation mode, connected to a computer for operation passThe complete 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.

Software functions* It 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, and print reports online.

Rich switch contacts 10Road contact input and8Output to the air contact point. Input contacts are null contacts and0~250V potential contacts are compatible and can be intelligently and automatically recognized. input、The output contacts can be expanded according to user needs.

large screenTFT display screen This machine adopts800 × 600 dot matrix large screen TFT high-resolution true color LCD display, 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.

self-protection Adopting 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.

Having independenceDedicated DC power output The device is equipped with one channel110V and 220V dedicated adjustable DC power output.

cost-effective It belongs to cross disciplinary joint design products, integrating advanced technological achievements from multiple disciplines. Combining the performance of a large testing instrument with the price of a small testing instrument, it has a high cost performance ratio.
