Intelligent Compact Air Insulated Switchgear / Vacuum High Voltage Switchgear
Description:
KJZ3-1500/3300 mine use FLP and I. S. Intelligent switchgear is suitable for underground mines containing methane mixture gas and having potential danger of coal dust explosion. It provides start/stop, two-speed switching, master and slave sequential control of drum shearer, AFC, stage loader and crusher in a fully mechanized coal face on the power supply lines of a. C. 50Hz, 3300V. It also provides protection of electric motors and power supply lines. The DSP system of switchgear can integrate with the built-in monitoring system of the shearer for achieving data transmission among face equipment, sequential operation, and automatic control of all the equipment in a fully mechanized face. The switchgear has auxiliary power supplies of 127V and 220V for external illumination and control.
Competitive Advantage:
Digital signal processing (DSP), CAN bus, self-adaptive detection, network interface, Chinese character LCD, self-diagnosis of fault, incoming and outgoing cables joined by cable connectors. The built-in shearer monitoring system.
