CPS that "the control and protection of electrical switches" is a new type of low-voltage electrical products, is the latest development of our country to fill the gaps in the generation of product categories, as a new category of products, its product categories, code-named "CPS", English " Control and Protective witching Device "abbreviation, the products meet IEC60947-2 (1997)" Low-voltage switchgear and control equipment Part 6: Multiple function equipment Section 2: Control and protective switching devices "and GB14048.9-1998" low switchgear and control equipment multifunction devices (or equipment) Part 2: Control and protective switching devices (or equipment). " Function and use JKCPS (KB0) Control and protective switching devices using electromagnetic actuator to drive the movement to contact and breaking the circuit. All protective features and functionality through intelligent control unit and the current transformer sampling, after making logical operations and data processing, controlled release of the action, complete fault diagnosis and protection. Switch on a single low-voltage electrical implements circuit breakers, contactors, thermal relays and other low-voltage electrical functions in intelligent control have advanced level ranks. JKCPS (KB0) The main features are: in the form of intelligent product structure "from the match," the control and protection functions. The functional integration "circuit breaker (fuse) + contactor + thermal relay", it is possible to replace the traditional circuit breaker (fuse), contactors, overload (or over-voltage, phase) protection relays, isolators and other The traditional separation of electrical species. The separation of the control and protection devices on the main function of realization: off load current, short circuit protection, overload protection, undervoltage protection, emergency measures under state control, emergency stop and interlock. However, due to different manufacturers there are some differences in the electrical properties of the product market, as well as the choice of personnel and other reasons there are differences in the use of technical parameters, making complete sets of equipment consisting of unreasonable work endless reliable. In addition, the electrical device is composed by a separate control box, when you consider the needs of arcing distance and cooling, the cabinet itself nor can be made smaller. Multifunction Control and protective switching devices used, a significant reduction in the variety and number of lines required components for the design of low-voltage power distribution and control systems simplify provides an ideal foundation elements. But also greatly simplify circuit design, making electrical complete sets of equipment reliability, security greatly improved, but also makes the production, commissioning and routine maintenance in the future accordingly simple and easy. Especially after the adoption JKCPS, compact and flexible structure changed in the past had to adopt separate devices into a large box and stupid situation, especially for land-use tensions building electrical design, especially for embedded civil Concealed wall. In addition, from a comparative analysis of the technical and economic point of view, if the traditional "circuit breaker or fuse + contactor + thermal relay group" barricaded more control circuits, the price is not cheap, and easy enough due to careful selection of parameters and other causes composed of complete sets of equipment is not reasonable, not high reliability. Therefore, CPS products come out, will bring low-voltage electrical appliances to "integration" change the development of intelligent, has broad application prospects. The type and purpose of the main parameters of the main product type modules and accessories have a short-circuit protection (similar to the MCCB and fuse short-circuit protection), automatic control (similar to contact the remote control function), local operation and indication.

The controller turns on the motor or the distribution circuit signal sampling, calculation and analysis of embedded software by issuing the appropriate treatment instructions, control JKCPS off the main circuit and according to two sets of output contacts signal, according to the requirements of selection. Use is divided into a variety of types, types and specifications. Auxiliary contacts (mechanical passive F-type and L-type) with the main circuit contacts linked with electrical control and indication. Divided by the number of contacts on a variety of specifications. Provides eight pairs of auxiliary contacts simultaneously. Signal alarm contacts (mechanical passive) with F-type auxiliary contacts integrated with the operating mechanism linked with work status and cause of the malfunction indicator. With three pairs and two pairs of signals while providing any alarm contacts. Isolated auxiliary contacts (mechanical passive) and isolated operating mechanism linkage, to achieve control circuit or (and) auxiliary circuit isolation indicator that provides two pairs of auxiliary contacts simultaneously. Panel sets the operating mechanism mounted on the device panel, without opening to place on JKCPS operations, including turning, breaking, then buckle (reset). With a variety of different forms of mounting direction and specifications. The control circuit conversion module for AC-DC converter control circuit, low voltage control (such as a PLC direct control) function. Zero sequence transformer for detecting residual current in the primary circuit, the signal is transmitted to the controller.
