ZYCPS-45 Control and protection switchgear

Overview
Control and Protective Switching Device stands for control and protection switching equipment. It is a new product in low-voltage electrical appliances, referred to as CPS.
The ZY series of control and protection switch appliances produced by the company are based on the requirements of smart grids. They integrate the main functions of separate components such as circuit breakers, contactors, overload relays, and isolation switches in a modular single structure form. Able to integrate various signals. Realize the self-coordination of control and protection features within the product. Improve the protection technology of the third-generation products. It has the advantages of small size, high short-circuit breaking performance index, long electromechanical life, high operational reliability, safe and convenient use, energy saving and material saving.
The company adopts advanced MCU and DSP control technology to develop the ZY-CPS series of control and protection switch appliances. It has high protection accuracy, stable and reliable work, strong anti-interference ability, and realizes the digitalization, intelligence, communication network and field bus connection of the control protection switch. Monitoring and other functions are a new generation of CPS products for smart grid projects.
ZY-CPS control and protection switch appliances adopt energy-saving technology, which has low control power consumption and stable and reliable performance.
This product complies with: National Standard GB/14048.9.

Main uses and scope of application
ZYCPS is suitable for electric control systems such as pumps, fans, air conditioners, and fire-fighting lighting in modern buildings: motor control and protection in metallurgy, coal, steel, petrochemical, ports, ships, railways, textiles, construction and other fields: Motor Control Center (MCC), especially intelligent electronic control system or high breaking capacity MCC (requires Ics to reach 80kA power distribution control system): single-motor control and protection of factories or workshops, and remote control of lighting systems, etc.
ZYCPS control and protection switching appliances are mainly used in power systems with AC 50Hz (60Hz), rated voltage to 690V, and current from 0.16A to 100A to connect, carry and break currents under normal conditions, including specified overload conditions, and can be connected Connect, carry and break current under specified abnormal conditions (such as short-circuit current). ZYCPS can perform comprehensive measurement of parameters, it is not only an executive protection mechanism, but also a comprehensive sensor.

Functions and features
◇High efficiency and energy saving, low temperature rise
ZYCPS control and protection switch appliances adopt new energy-saving technology, the switch electromagnetic system adopts the starting current circuit and the switch holding current circuit, the switch electromagnetic system is activated by AC, and the DC controlled by the single-chip microcomputer is kept closed. The working mode minimizes the switching electromagnetic system and short-circuit ring loss, and the coil copper loss is only about 40% of the original, thereby saving power to the greatest extent, and reducing the temperature rise and noise of the switching electromagnetic system.

◇Reliable performance and long life
The electromagnetic system of ZYCPS control and protection switch appliances adds a buffer device, which reduces the energy impact of the switch electromagnetic system, thereby improving the pull-in performance of the switch and prolonging the service life of the switch. ZYCPS control and protection switch electrical appliances adopt high-quality industrial-grade single-chip microcomputers and famous-brand electronic components, carefully designed circuits, and optimized design from both hardware and software aspects of the product to reduce electromagnetic interference and improve product reliability.

◇The specific features are as follows:
1. It has the functions of remote automatic control and direct manual control on the spot:
2. It has the function of panel indication and electromechanical signal alarm:
3. It has the time-current protection of coordination and cooperation (with long delay, Short-circuit short time delay, and instantaneous three-stage protection characteristics);
4. With phase failure, overcurrent, locked rotor, short circuit, undercurrent, overvoltage, leakage, three-phase unbalance, start delay (avoid high start current, Distinguish from the overcurrent action time) and many other functions:
5. The monitor adopts LED display for various operation, fault and other states, and has the functions of voltmeter and ammeter;
6. Equipped with setting keys, moving keys, data keys, and reset keys , Various parameters can be set and inquired: Since the MK-KB0 control and protection switch appliance adopts MCU's E2PR OM storage and memory technology to realize parameter setting, the parameters that have been set are still stored in the MCU after the power is turned off. No need to set parameters:
7. With fault memory function, it is convenient for fault inquiry and analysis:
8. With RS485 communication interface, open field bus (MOD BUS protocol, etc.), it brings convenience to the user system integration and facilitates the user to realize intelligent management :
9. Users can select functional modules or accessories according to their needs to realize the control and protection of various motor loads and power distribution loads.
