　　Relay protection device testerMeeting the requirements of steep slope construction, large aperture, and various geological composite applications in industries such as photovoltaics and wind power generation, it has changed the previous situation of small aperture, slow rock drilling speed, and inconvenient transition of photovoltaic drilling rigs, and opened a new era of photovoltaic drilling.

Product Overview

The relay protection device tester can calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and can simulate various complex instantaneous and conversion faults for whole group testing

Product features of relay protection device tester

Flexible combination of voltage and current output - with standard 4-phase voltage and 3-phase current output, it can easily perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current of the third phase can output 120A. The fourth phase voltage Ux is a multifunctional voltage item that can be set to 4 types of 3UO or detect synchronous voltage, or output any voltage value. Easy standalone operation - the device panel is equipped with a trackball mouse, optimized keyboard, and a large screen TFT LCD display, with built-in full Chinese Windows platform operating software. Ready to use upon startup, easy and fast to operate.

Dual operation mode - In addition to standalone operation, the device can also be connected to an external laptop or desktop computer for operation. The functions of the two modes are the same, providing a truly complete dual operation mode.

The new high fidelity linear amplifier - the output end has always insisted on using high fidelity and high reliability modular linear amplifiers, rather than switch type amplifiers. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current throughout the entire process.

High performance host - The output part is controlled by DSP, with fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution DIA conversion control. The output waveform has high accuracy, low distortion, and good linearity. The device adopts a large number of advanced technologies and precision component materials, and has undergone specialized structural design, resulting in small size, light weight, comprehensive functions, easy portability, and can work immediately after startup. Flow testing is very convenient.

Software Function * - It can complete various large-scale complex verification tasks with high automation level, conveniently test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online. There is an independent dedicated DC power output device with one 110V and 220V dedicated adjustable DC power output. Rich contacts - with 8 input contacts and 4 output contacts. The input contacts are compatible with both empty contacts and 0-250V potential contacts, and can be intelligently and automatically recognized.

The complete interface device panel has a built-in keyboard and mouse, which can be operated independently or externally through the keyboard and mouse interface; It also has two USB ports and RS232 ports, which can communicate with computers and other external devices.

*The self-protection function

The heat dissipation structure design is reasonable, the hardware protection measures are reliable, and it has functions such as power soft start, software self diagnosis of faults, and output locking.

Lightweight, compact, highly integrated single machine and integrated structure - adopting a large number of high-tech and carefully designed ultra lightweight and compact structures, making the whole machine extremely small and lightweight.
