Brand: Shanghai nine open model: JKCPS structural characteristics: the main structure of a body JKCPS mainly by the base, the electromagnetic mechanism, operating mechanism, the main circuit contact group, MCU intelligent control detection system, electronic trip unit system components. 2, the electromagnetic mechanism JKCPS electromagnetic mechanism mainly by coils, core, control contact, base, etc. (similar to the electromagnetic contactor control system with under-voltage protection function), can accept on-off operation instruction, by controlling the main contactor The main contact is turned on or breaking the circuit. JKCPS electromagnetic organizations to adopt a new energy-saving technology, the core loss and loss of short-circuit ring switch electromagnetic system to minimize the greatest degree of saving energy. Increasing the buffering means to reduce the impact of the electromagnetic energy system, thereby improving the performance of pull switch, to extend the life of the switch. 3, the operating mechanism JKCPS operating mechanism can accept short-circuit signals and control signals from the fault detection system MCU intelligent contacts per pole, cut off by controlling the shock coil circuit, by breaking the main circuit electromagnetic agency. So after troubleshooting reset by operating knob. 4, the main circuit contact group (including contact system, short-circuit release) JKCPS main circuit contact group by double-break contacts bridge, gate films interrupter Speed ??limiting short-circuit releases, each pole independent . The main circuit contact group Speed ??limiting and short-circuit release extinguishing system high breaking capacity, high current limiting characteristics (limiting factor of less than 0.2) the back-up protection, tripping setting current value: 16In ± 20% its value can not be adjusted, only frame degree related. When the load is applied in short circuit occurs, rapid release (2 ~ 3ms) the impact of opening the main contact group, while driving the operating mechanism to control the coil off the main circuit is completely disconnected. Scope: JKCPS has the control and protection functions integrated, modular structure, small size, to the high level of environmental protection, easy installation and maintenance operations, such as a series of advantages. Especially for modern building pumps, fans, air conditioning, fire lighting and other electronic control systems; metallurgy, coal, iron and steel, petrochemicals, ports, ships, railways, textiles and other areas of the motor control and protection; motor control center (MCC) factory or workshop motor control and protection; and remote control of lighting systems. JKCPS mainly used in AC 50Hz (60Hz), rated voltage up to 690V, current self 0.4A to 125A power system in turn, carrying and breaking currents under overload conditions, including requirements under normal conditions, and the ability to access, load and Current (such as short circuit current) breaking down under the abnormal conditions. Performance: JKCPS single modular structure, integrated circuit breaker (fuse), contactors, overload (overcurrent) protection, under voltage, phase loss protection, voltmeter, ammeter, leakage, isolation and other electrical components integrated functions. Application MCU digital processing technology, high accuracy, good linearity, accuracy and reliability of fault resolution, anti-interference ability. Its features are as follows: 1, with remote automatic control and in situ direct manual control function; 2, with the panel instructions and electrical signal alarm function; 3, with coordination of the time - the point of protection features (with a long delay, short circuit short delay, instantaneous protection features three sections); 4, with phase, overcurrent, stall, short circuit, under current, overvoltage, undervoltage, leakage, phase imbalance, isolation, start delay and other functions; 5, the monitor on a variety of operating, failure status with LED display. With a voltmeter, ammeter function; 6, with a set key, shift built data keys, reset button, you can set various parameters and query; due to the use of the MCU JKCPS E2PROM memory storage technology, parameters can be set after Save power failure; 7, with fault memory function, easy fault finding, analysis; 8, with RS485 communication interface, open fieldbus (Mod Bus protocol, etc.), bring convenience to the user system integration, user-friendly intelligent management 9 Users needed matching function modules or accessories, you can achieve all kinds of motor load, the load distribution control and protection.
