CPU structure Generally speaking, the structure of CPU can be roughly divided into operation logic components, register components and control components. The so-called operation logic unit, mainly able to carry out related logic operations, such as: can perform shift operation and logic operation, in addition to can also perform fixed point or floating-point arithmetic operation
①, current protection: (according to the setting principle of protection, protection range and principle characteristics) A, overcurrent protection - is to avoid the maximum load current that may appear in the protected equipment or line to set. Non-fault current, such as large motor starting current (short time) and traversing short circuit current, to ensure the
The relay protection device should meet the requirements of reliability, selectivity, sensitivity and quickness: the four "sex" is closely related, both contradictory and unified. selectivity -- Indicates that the fault is first removed by the protection of the faulty device or circuit breaker. When the protection of the faulty device or circuit breaker refuses to
In comparison, the use of wireless DATA transmission module to establish a dedicated wireless data transmission mode than other ways have the following advantages, the following introduces the use of data-6106 wireless data transmission module to establish a dedicated wireless data transmission mode compared to the advantages of wired communication. Cheap cost Cable communication mode
Classification of IGCT In terms of internal structure, IGCT can be divided into the following three categories: (1) Asymmetric It is a pure PNPN thyristor structure. The device can withstand high voltage in the forward direction, but it does not have the ability to withstand reverse voltage and cannot flow through reverse current. It is
The SCM-1 module consists of three boards connected by an eight wired bus on the front side (not the backplane bus). The boards for SCM-1 are named SCM-A, SCM-B and SCM-C and these names can be found on the boards. SCM-A board: Two relay-boards OPR-1 can be mounted. One for output for a mechanical speed
S600 I/O for Advant Master DCS Support and migration of ABB S600 I/O for Advant Master DCS, local rack based I/O for Advant Controller 110 and Advant Controller 160. The S600 I/O series serves as the local, rack-based I/O for the Advant Controller 110 and the Advant Controller 160. There is a full complement of
HYDRAN M2 on-line monitoring system for faulty gas in transformer oil General specification Based on field-proven technology, the new Hydran M2 adds a mathematical model of the transformer based on IEEE® and IEC® standards to provide real-time transformer overview information. This is not only to monitor dissolved gas and humidity, but to expand to monitor
