YSB9100 Intelligent Bidirectional Station Branch Recognition Instrument

1、 Product Overview

YSB9100Intelligent bidirectional substation branch recognition deviceIt is a testing instrument that integrates functions such as user identification in the substation area, line branch identification, electrical independence testing between substations, basic electrical parameter testing, and measurement of voltage and current harmonic content. This instrument adopts advanced special zero crossing low-frequency carrier technology and pulse current transmission and detection technology in the industry, which can effectively ensure accurate identification of users in the substation area with a measurement radius sufficient to cover various power supply distances. There is no problem of power carrier wave crosstalk, short transmission distance, large load impact, and common cable interference in the case of multiple short distance and high voltage shared by multiple substations; The recognition success rate can reach100%.

YSB9100Intelligent bidirectional substation branch recognition deviceBuilt in large capacity power failure without losing data storage, can save on-site verification data, up to storage capacity1000The on-site verification results can be provided with backend microcomputer management software to upload the results to the computer for computerized management. The instrument adopts an independently designed and molded engineering plastic shell, which has a beautiful and practical appearance. The on-site testing operation is convenient. When operating this device, the rear bracket can be opened and placed on the desktop for use, or it can be operated handheld.

IIFeatures

1、The high-power load signal transmission communication method ensures that the theoretical communication distance meets the power supply range of any substation area.

2、The special pulse current emission and detection method ensures that there will be no signal errors due to the proximity of the common high voltage in the adjacent station area.

3、Fast and convenient station identification function, initiated by extension, testing time not exceeding6Second, accuracy of results100%The results show that the content description is simple, clear, and explicit, including the transformer substation area number where the tested user is located and the phase where the tested meter is located（AXiangBXiangCThe situation and display results are intuitive.

4、Branch recognition function, accurately identifying the branch of the power supply line in the area where the tested user is located, and a single host can detect it simultaneously3Multiple branches and multiple hosts working simultaneously can be expanded to18A branch.

5、Equipped with mutual testing function between substations, multiple hosts can work simultaneously to accurately determine the independence and electrical connection relationship of each tested substation.

6、Equipped with phase sequence discrimination function, capable of distinguishingABCIs the phase sequence of each phase "positive phase sequence" or "negative phase sequence".

7、Flexible pliers (optional) are used for current detection50AClamp table100AClamp table250AClamp table and500AClamp table).

8、Multiple working modes can be freely selected, with convenient combinations and flexible settings; It has multiple communication methods such as independent transmission of load power signals, independent transmission of current pulses, and comprehensive transmission of load power signals and current pulses.

9、Multi machine working mode, the instrument is not divided into main and sub units, and each device can be set as a main or sub unit; Support three modes: one master multiple points, multiple masters one point, and multiple masters multiple points, which are convenient for users to use and can effectively improve work efficiency.

10、Accurately measure three-phase voltage and pulse current.

11、The instrument can display the situation of voltage phase loss and automatically give a prompt on the LCD screen.

12、The instrument can detect three-phase voltage2－48Measure subharmonics.

13、Vector graphics display function. The instrument can display the vector relationship diagram of three-phase voltage and three-phase current, which is convenient for checking the misconnection of low-voltage user measuring devices.

14、Simple oscilloscope function. The instrument can display the actual waveform diagrams of three-phase voltage and three-phase current, allowing users to have a clear understanding of the waveform situation of the measured user.

15、The instrument has a self checking function. When some components are damaged due to overvoltage, impact, or other reasons, the instrument should diagnose the faulty part and provide correct prompts.

16、The instrument has the function of automatic identification of neutral and live wires. When the unit is conducting station or branch testing, it will automatically identify whether the neutral and live wires are connected correctly and provide a prompt on the screen

17、Adopting a large screen true color full transparent LCD screen, it is still clear under sunlight. Chinese and graphical display, user-friendly interface, intuitive display, and simple operation.

18、The conductive silicone button operation mode is designed reasonably and easy to operate. It has a long lifespan and high sensitivity, avoiding the possibility of malfunction or poor sensitivity that may affect the normal use of the touch screen after a period of use.

19、The instrument can save the test results of the station area in the form of records, including test date, test time, station transformer number, meter number, and phase.

20、The test records can be passedUCopy the disk and other mobile storage devices to the backend management computer for centralized management, which can classify and summarize data records, facilitating the marketing department to truly grasp the information of each household's station area ownership, phase ownership, branch ownership, etc; Accurately calculate information such as load distribution and line loss rate.

21、In order to ensure the safety of operation, the instrument has multiple protections. The power circuit has independent and quickly replaceable protective components. In device applications, if the wire voltage is mistakenly connected during wiring, the instrument ensures that there is no damage and provides a prompt for the misconnection situation, and the instrument cannot perform testing operations.
