According to eighteen Major Anti-Accident Measures of State Grid Corporation of China, BWDJ series of full-function insulation online monitoring device produced by our company has the recording and alarm functions of ALTERNATING current and dc system, and can upload corresponding alarm information to the background host. According to the anti-accident measures, The State Grid Corporation of China requires that the DC insulation monitoring device be upgraded accordingly. Therefore, in view of the problem that the old station cannot be transformed by power outage, our company has developed a new open and closed DC leakage current sensor, so as to realize the on-site installation and debugging under the condition of continuous electricity. The sensor transmits the collected digital quantity to the host computer by means of communication, which avoids the interference of the field environment to the collected data and greatly improves the reliability.

● Rated voltage of DC system

● Device working power supply

● Number of dc system branches, number of sensors required.

● Provide up and down computer communication interface RS232 (or RS485), when special data communication, please provide communication protocol.

Functions and Features

● Can accurately display the voltage amplitude of THE AC series into the DC system, give the alarm signal and upload the relevant information to the background.

● Open and close DC leakage current sensor is used to facilitate on-site transformation without power failure.

● Real-time monitoring and display two SECTIONS of DC bus positive and negative to the ground voltage and insulation resistance, can detect the positive and negative bus to the ground insulation resistance drop at the same time; Detect monopole multi-point grounding and bipolar multi-point grounding.

● The use of improved balance bridge detection method and unbalance bridge detection method, detection process of positive and negative bus to the ground voltage disturbance ≤±10%.

● Upper and lower computers through RS232 or RS485 communication, communication protocol includes: Xu, Otron, Modbus-RTU three protocol.

● The device can provide ac voltage amplitude, DC bus voltage, insulation, fault type, branch insulation resistance and other data.

● Unbalance bridge cycle action can be started regularly to detect the failure of positive and negative bus insulation falling simultaneously.

● Can query sensor status and branch insulation status information; You can query the communication status of master and slave computers and transfer branch information from slave computers.

● Can display 4 ongoing faults at the same time; In addition, the system can record 30 pieces of fault recall information, and each piece of fault recall information records the status information of 10 branches.
