Intelligent Explosion Proof Switchgear MA Mine Security 400A

Description:

KJZ-1500/1140Z flame-proof and intrinsically safe type intelligent vacuum switchgear is suitable for use in underground mines containing methane mixture gas and prone to dust explosion. On power supply line of 50Hz and1140V it controls start/stop, sequential control or dual speed switching of equipment, such as, shearer, AFC, stage loader, crusher, emulsion pump, spray pump, etc, and provides protection of electric motors and power supply lines. Combination switch used for isolating switch, the rated current shall be the is less than the sum of the load current in isolating circuit; Used to control the motor, the rated current generally take 1.5 ~ 2.5 times rated current of the motor.The switchgear is provided with auxiliary power supplies of 127V and 220V for external illumination and controlling systems.

Competitive Advantage:

Digital signal processing, CAN bus, self-adaptive detection, network interface, Chinese (English) character LCD, fault detection, rapid plug-in drive unit, incoming & outgoing cables connected by cable couplers.
