Product Overview

Description

 

 

General Information

 

GDJB-802 3 Phase Secondary Current Injection Relay Protection Test Device plays a key role in operating electricity power systems reliably and safely. It can automatically judge over-current, over-voltage, overload, short circuit, high temperature, abnormal data and warning prompts for misoperation. In addition to the verification of various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can also simulate single-phase to Three-phase transient, permanent, and transitional faults are tested for the entire set. It can also complete various large-scale and complex calibration tasks with a high degree of automation, can automatically test and scan various protection settings, store test data in real time, display vector diagrams, and print reports online.

It can independently complete device testing in professional fields such as microcomputer protection, relay protection, excitation, measurement, fault recording, etc. It is widely used in scientific research, production and electrical test sites in electric power, petrochemical, metallurgy, railway, aviation, military and other industries.

 

 

 

 

 

 

Features

 

l Standard 4-phase voltage and 3-phase current output, which makes it easy to carry out and combine with various outputs for various types of protection tests. Each phase voltage can output 120V, single phase current max. Output 40A(10s), current three parallel can output 120A. The fourth phase voltage Ux is a multi-functional voltage term. It can be set as four kinds of 3U0 or synchronization voltage, or output at any given voltage value.

 

l Single computer is easy to operate. Single computer is operated by a flexible and convenient revolving mouse through a large LCD screen. All of them are displayed in English. It can complete most of the test and verification work in the field. It can check all kinds of microprocessor-based protections relays and simulate all kinds of complex instantaneous, permanent and switching faults to carry out a whole set of tests. It can be used immediately after booting, and it is convenient and fast to operate.

 

l Dual operation mode, connecting computer to run through a complete set of English operating software on Windows platform, can carry out various large-scale, complex and more automated verification work, can easily test and scan various protection settings, can store test data in real time, display vector diagram, draw fault waveforms, online printing reports and so on.

 

l The software has powerful functions and can complete various large-scale and complex verification tasks with high automation, such as three-phase differential test, fast switching of auxiliary power supply, standby self-switching test, synchronous reclosure of line protection inspection, etc. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector maps, and linked with computer and printing report, etc.

 

l Switching quantity contacts enrich ,8 channels of contacts input and 2 pairs of empty contacts output. The input contacts are compatible with empty contacts and 0-250V potential contacts, which can be recognized automatically and intelligently. Input and output contacts can be extended according to user ‘s need.

 

l Large screen LCD display adopts 320*240 dot matrix large screen high resolution graphical LCD display. All operation processes are set on the display screen. The operation interface and test results are displayed in English, and the display is intuitive and clear.

 

l Self-protection , adopts a reasonably designed heat dissipation structure, and has reliable and perfect protection measures, soft start of power supply, and certain fault self-diagnosis and locking functions.

 

l It has an independent dedicated DC power output , equipped with a single 110V and 220V dedicated adjustable DC power output.

 

l High cost performance is a cross-professional joint design product, which synthesizes the advanced scientific and technological achievements of many professions. It has both the performance of large tester and the price of small tester, and has a high performance-price ratio.
