product introduction:

WDQXThe intelligent remote control device (hereinafter referred to as the remote control device) is suitable for traction power supply catenary system with rated voltage DC1800V and below and rated current up to 2000A. It can be used as a catenary power access, isolation, load transfer and catenary disconnection detection device to realize the functions of voltage acquisition, voltage protection, isolation operation and operating environment monitoring at both ends of the isolating switch.

product features:

  1. Real-time data acquisition: the device exchanges data with the system monitoring master station through 4G/5G wireless communication network, and the system can monitor the real-time data information of the remote control device through the real-time data acquisition interface, such as the voltage value, voltage difference, ambient temperature, battery voltage, etc. at both ends of the isolating switch;
  2. remote control device: remote control of remote control device can be realized, and safety check measures are provided;
  3. WIFIOperation: The device supports the connection with PDA terminal through WIFI in situ, and realizes the functions of data reading, information inquiry, parameter setting and simulation control without opening the box.
