Let's look at the advantages

• The equipment adopts a bistable permanent magnet high-voltage fixed circuit breaker with a rated breaking current of 31.5KA
• The electric trolley adopts intelligent servo control, which can be controlled on site, or the automatic plug-in and exit of the ground remote control trolley
• Wtg-800 high voltage intelligent integrated protection device of the equipment adopts high-performance microprocessor as the protection and monitoring core, with strong data processing ability, fast operation speed and stable and reliable operation
• The human-computer interface uses large-size Chinese color LCD display, which can intuitively and clearly display the current system status and various operating parameters, and the operation is very convenient

• It has standard RS485 communication interface, can bus interface, optical fiber interface and video interface, provides standard communication protocol, and has four remote functions to facilitate the establishment of substation site monitoring system, and realizes remote centralized monitoring and monitoring on the ground, so as to realize unattended supervision of the substation

About its powerful features

• It has multi-point wireless temperature measurement and early warning function
• The video of trolley isolation fracture can be monitored in real time on the underground site and on the ground to realize remote visual operation
• It has the current protection function against skip tripping
• The equipment can measure the active and reactive kwh by sections, and distinguish high, peak, level and valley
• The voltage loss delay tripping function can be selected to avoid large-scale power failure when the mine power grid loses power due to fault or lightning stroke

• It can display fault status, query fault records and provide assistance for equipment maintenance
• It has the function of front door simulated leakage test
• The protection function can be switched on or off
• It has the function of fine adjustment and calibration of measurement parameter error
• Adopt remote control intrinsically safe operation circuit.

So, why choose it？
It is a necessary condition for realizing intelligent mine construction and unattended: the man-machine interface adopts LCD color display, and the front door panel is equipped with display observation window and operation buttons. Through the observation window, you can see the real-time operating parameters of the equipment, such as the operating status, three-phase voltage, load current and clock, and can realize the function setting and parameter calibration.
