CKJ512-F Mining Flame-proof and Intrinsic-safety Power Supply Monitoring Substation

Application

The CKJ512-F monitoring station can be used in the Ethernet switch, communication management machine,video coder, power supply panel, isolation fence, ups electrical source and explosion proof shell.

The CKJ512-F monitoring station is especially designed for the underground monitoring, mainly used to realize communication between ground working station and the ground station, the real data of electricity, working situation will be uploaded, the control and the detecting and control can be realized, as well as the device protection and the order can be achieved.

Monitoring station of the CKJ512-F is equipped with video monitoring system and PLC monitoring system, all system signal will be delivered to the ground.

The CKJ512-F monitoring station, expect the single formed double circle optical fiber, it can also be connected to the Ethernet without adding additional connecting devices.

Features

Powerful industrial level 32bit processor can work reliable.

Communication way is smart and it supports multi protocol, multi baud rate and multi communication way.

Adapting the real time operating software.

Communication and monitoring software is in plug-in modules which is an easy expansion and convenient to complete the data exchange between the protection devices and the ground attemper and monitoring system, and to achieve the focus local control center can continue to work for more than 2 hours and transmit the fault information to the ground workstation after power-down.

The optical switch is installed in the CKJ512-F branch station. It is convenient to form an optical Ethernet ring.

This branch station support the remote maintenance and remote monitoring.

The LCD display screen will display all the record data of current, voltage, switch status and fault of transformer substation.

It can connect to the intelligent equipment.

CKJ512-F Mining Explosion-proof and Intrinsic-safety Power Supply Monitoring System

Data exchange function between protection devices and ground attempter and monitoring system.

It can receive and record the control order from the ground attempter center.

According to the order from the ground attempter center, it can collect the data of remote measure, remote communication, series fault record, tape-recorded wave data and transmit to the ground work station.

It has the open/close functions according to the order from the ground attemper center.

Monitoring function in local focus center

Monitoring the switch status.

Real-time display functions of current, voltage.

Recording and display functions for big accident.

Comprehensive selecting creepage function in the electrical circuit.

Cooperating with HRG-7RT/HRG-7FYRT comprehensive protection device complete selective single phase grounding function in the transformer substation to indicate that the grounding line and grounding phase have time function via fault record and signal.

Complete the time function from the attempter station to the comprehensive protection device. The main attempter station will check one time for each 30 min and the branch station will check for each 15 min to insure the time is same.

The branch station will monitor the real time working status of the comprehensive protection device. When there is a new protection device, the branch station will  monitor the real time working status of the comprehensive protection device. When there is a new protection device, the branch station will be active to keep the tome same with the new protection device.

Conversion function of stipulations of an agreement.

Statute of plug-in expansion modules, you can easily access third-party smart device.

Remote maintenance function

Remote monitor the communication status, remote update the software, remote maintenance for data, remote download the tape record wave data, visit the branch station communication server to update the software and download the tape-record wave data via telnet or ftp.

Data storage function after power down: when the system is power down, the information and transmission will go on.

Monitoring of the communication status for each protection device.

When communication of the protection device is shut down, it will come into being a communication breaking record. This record will display and be sent to the ground attempter and monitoring center.

Real time monitoring all the operations of control.

The modification order from the main station for setting value: when the order is sent to the comprehensive protection device and the protection device is executed, the branch station will make a record.

The control order from the main station for the switches: when the protection device  has a tape-recorded wave data, the branch station will ask this data from the protection device and form three file of hdr, cfg.

Distant maintain function: the communicate statement can be monitored, the software can be remotely upgraded as well as the data downloading; using Telnet and ftp, the operator is allowed to loge in the serving,which is able to upgrade the software, and down loading the files.

The data will be maintained if the electricity loose: when the system is suddenly shut down, the system will automatic ensure all kinds of information will be maintained and delivered.

The monitor system of the each protector: when the communication is cut, a event record will be provided, which will also be sent to the ground monitoring center.

All controlling movement will be real-time monitored:

Receive the order of data changing, then the order will be strengthened and delivered to the integrated conservation, then after the order is strengthened, an event record will be produced ordered by the station.

After the station switch received the control order, and the order of integrated conservation, the station will produce a event record.

The storage function of the record:when there is a record in the integrated conservation,the station will ask for the record file and put them into the hdr,cfg files.
