Description
Mining explosion-proof lighting integrated protection device
Application: ZBZ2-6,10,12.5,16 / 1140 (660) M lighting signal integrated protection device (hereinafter referred to as lighting integrated protection) is applicable to the coal mine containing coal dust and explosive gas (methane). It controls the power supply of 127V grade lighting signal equipment, and the power supply is introduced as 50 Hz, 1140 V or 660 v.Technical advantages and functional features:1,This device takes microcomputer as the control core to carry out real-time monitoring and control of the operation status, and reliably realize various protection functions;
2, with fault query, fault records, temperature detection, large Chinese LCD display and menu-based operation;
3,With manual power supply, automatic power supply free choice of function;
4, with a long-distance terminal protector, realize the long-distance short-circuit protection function;
5,It has the function of setting various time to control the automatic power supply;
6,With RS-485 communication function, it is convenient to realize remote monitoring and control.
7, the use of dual-cavity structure, that is, by the dry-type transformer cavity and control cavity composed of this unique structure, to solve the past due to the dry change of the temperature generated by the impact of the device, improve the service life of the product;
