ZKJB-2000 intelligent switch monitoring protection device - focus on classic
The following is a brief introduction to ZKJB-2000 and ZKJB-2000A intelligent switch monitoring and protection devices:
1.ZKJB-2000 intelligent switch monitoring protection device function and characteristics
(1) Double CPU design, protection operation and display management are separately configured, so that the stability and operation speed of the product can be guaranteed at the same time; (I-type 16-bit high-speed single-chip microcomputer + 8-bit high-speed single-chip microcomputer; Type II 32-bit digital special-purpose processor DSP +16-bit high-speed single-chip ARM
(2) ZKJB-2000 intelligent switch monitoring protection device adopts new high-speed and high-precision A/D converter, internal sampling and holding and synchronization circuit, no external adjustment components, good conversion speed and stability, and low power consumption. With the high-precision measurement module, it can not only ensure the measurement accuracy (measuring accuracy up to 0.5), but also guarantee the real-time and accuracy of the protection algorithm.
(3), configuration of large-capacity RAM? And non-volatile memory, used to store protection settings and events and fault recorder data, power loss is not lost, and long-term memory failure information;
(4) High-precision clock design facilitates system-wide clock synchronization;
(5) It can be digitized, on-line setting protection value and various operation parameters, and the maintenance of setting value is safe and convenient;
(6) Real-time display and transmission of various operating conditions and data for local and remote monitoring and control; both telemetry, remote control, remote signaling, and power integration;
(7) ZKJB-2000 intelligent switch monitoring and protection device comes with the operation loop, and it can directly jump and close the switch without additional equipment;
(8) The product adopts full Chinese liquid crystal display. The keyboard and remote control operation make human-computer interaction convenient and quick, and the display interface is friendly and easy to understand.
(9) ZKJB-2000 intelligent switch monitoring and protection devices all adopt industrial-grade chips, with perfect electrical isolation and electromagnetic shielding design, strong and weak electricity separately arranged, fully enclosed iron shell chassis, so that the hardware system of the device has a higher resistance Interference ability and work reliability;
(10) Highly integrated circuit board design. The structure is simple and reliable. The main circuit board adopts multilayer board technology and surface component placement technology (SMT), which has low power consumption and high integration and improves device reliability.
(11) Three-stage protection can be set as quick-break, over-current and overload protection respectively, each protection current and time setting can be set independently, which is convenient for the protection of the upper and lower levels in the system, avoiding the protection of level tripping.
