Product Description

Mining explosion-proof vacuum feeder switch

Application
  KJZ-500,630/1140(660) Mining explosion-proof vacuum feeder switch.Used in coal mines, in AC 50Hz, rated voltage of 660V or 1140V, rated current to500, 630A three-phase neutral point undergrounded power supply system, as a main switch or branch switch, but also as a large-capacity motor infrequently for starting control.
  The protection system uses high-performance microprocessors and large-capacity new chips for dual-chip work, coupled with high-precision data processing and advanced protection algorithms, with high protection accuracy and fast response speed. Can complete overload, short circuit (divided into phase sensitive protection and current amplitude protection), leakage lockout, leakage protection, selective leakage protection, undervoltage, overvoltage, three-phase imbalance, gas lockout, wind power lockout, power metering and other protection functions, and have communication networking functions.

Characteristics

1. With Chinese character LCD and menu type human-computer interface, the operation is intuitive and simple. The current time, three-phase current and grid voltage, active power, insulation resistance, main / opening switch, operation status (closing / opening),, wind power locking and fault information are displayed in real time during operation;
2. The parameters of various protection functions can be adjusted through menu selection, with wide application range and high protection accuracy;
3. It has the function of "memory". The parameters of each protection function adjusted each time are memorized and saved. The parameters set last time are automatically extracted when the system is powered on or reset. Moreover, the protector can also memorize the fault information, which can be displayed through the menu, which is convenient for maintenance;
4. The function of setting value adjustment, protection test and information inquiry can be conveniently carried out through the button on the door;
5. The data communication interface can be selected to connect with the monitoring system, and RS485 or domestic leading power line carrier communication interface can be equipped according to the user's needs;
6. The protector adopts modular structure, optimized software and hardware anti-interference processing, and has friendly man-machine interface, which makes the installation, use and maintenance easier and the service life is greatly increased.
