Products applicable to a mine methane and coal dust explosion hazard, the installation of the low pressure side of the mobile substation to the various parameters of the low-pressure side of the grid to test the display, and fault protection. Widely used in underground coal mines, mine, metallurgical and mining. Product Attributes main features: 1 package consisting of high-voltage switchgear and transformer low-voltage side of the international advanced fault interrupter transformer high-side power operating mode. 2 All faults are driven by the high pressure side of the signal line vacuum breaker off, thereby reducing the breaking current, while overcoming the low-voltage winding of the transformer feeder switch to low-leakage circuit breaking point of failure can not be dead issue. 3 protective box is divided into four loops on both sides of the outlet, and more able to meet the load connected. 4 uses advanced technology imported industrial programmable logic controller to control the core, through the process to achieve a variety of computing and protection. Stable performance, protection precise and simple maintenance. 5 The use of advanced human-computer screen (GOT) conduct electricity parameter display and display interface characters fault, man-machine dialogue to set parameters (just set the rated current value, the other parameters PLC automatically generated). 6 box with overload protection, short circuit, leakage, leakage lockout, overvoltage, undervoltage, reserve trip protection. 7 Remote control: via RS485 communication. Other notes The main technical parameters: 1 Rated voltage: 1140V (660V) 2 Rated current: 50-1250A 3 overload multiple settings: 1-10 times 4 Leakage action values: 11K (660V) 20K (1140V) 5 leakage lockout value: 22K (660V) 40K (1140V) 6 Ex Type: flameproof product logos No.: Exdi Certificate of Conformity: 10721728U security Zhunyongzheng No.: MAC070353 transaction description Tyan Zhongcheng Mine Automation Co., Ltd.
