In August, the country’s power generation amounted to 390.3 billion kWh, a year-on-year increase of 12.6%, an acceleration of 3.3 percentage points year-on-year. Among them, thermal power increased by 9.9%, slowing by 0.6%; hydropower rose by 22.3%, accelerating by 18.6%. From January to August, the country’s power generation amounted to 2,700.5 billion kWh, a year-on-year increase of 17.2%, and the growth rate was 16.4 percentage points higher than the same period of last year. Among them, thermal power growth was 18.2%, a decrease of 1.5% over the same period of last year; hydropower growth was 10.7%, slowing by 1.1%.
The peak of power generation this summer occurred on August 13th, reaching 13.958 billion kWh, an increase of 14.4% from the peak of last year. Since most of the water supply is good, the major hydropower stations are in full power. The monthly hydropower generation increased by 22.3% year-on-year, largely replacing thermal power generation, reducing coal demand and alleviating coal supply during the peak summer period. situation. In August, the average daily coal consumption of major power plants nationwide was 3.737 million tons, a 3.8% increase from the previous period, which was lower than the average of around 8% in the same period in recent years. At the end of August, the coal stocks of key power plants were 58.6 million tons, and the number of days that can be consumed was more than 17 days.

Among them, the first industry's electricity consumption increased by 5.9%, down 0.4% year-on-year; the second industry's electricity consumption increased by 21.5%, a decrease of 2.8% over the same period of last year; the third industry and residential electricity consumption increased by 15.7% and 13 respectively. %, an increase of 5 and 1.6 percentage points year-on-year.
Industrial electricity consumption grew by 21.4% year-on-year, down 3% from the same period last year. Among them, iron and steel, non-ferrous metal smelting and processing, and chemical industry electricity consumption increased by 23%, 38% and 17.2%, respectively, fell by 4.5%, 9.9% and 7.4% in the same period last year; building materials industry electricity consumption increased by 20%, growth rate The year-on-year increase of 16.8 percentage points; the total electricity consumption of the four industries accounted for 44.1% of the industrial electricity consumption, the proportion increased by 1 percentage point year-on-year.
The average utilization hours of power generation equipment in the country was 3,163 hours, an increase of 210 hours compared with the same period of last year; among them, thermal power equipment was 3,419 hours, an increase of 317 hours.
A Small Computer System Interface (SCSI) connector, also pounced as [scuzzy" connector, is used for physically connecting and transferring data between computers and peripheral devices.
SCSI is the small computer system interface, which is an independent processor standard used for the system level interface between computer and intelligent devices (hard disk, floppy, optical drive, printer, scanner, etc.). It is an intelligent universal interface standard, which has the function of communicating with various types of peripherals. SCSI uses the standard software interface of ASPI (SCSI programming interface) to make the driver communicate with the SCSI adapter installed inside the computer. SCSI interface is widely used in high-speed data transmission technology on minicomputers. SCSI interface has many advantages, such as wide application range, multitask, wide bandwidth, low CPU utilization, and hot plug.
SCSI connectors type and interfaces
Centronics 50-pin connector: The Centronics 50-pin connector was once the most widely used SCSI connector. An external connector only, the Centronics is a SCSI-1 connector that looks the same as the Centronics cable that attaches to a parallel port printer. The Centronics 50-pin cable comes in male and female styles, and gender changers and cable converters are commonly available. Although used on older SCSI devices and external drive enclosures, this interface is no longer heavily used, due to its slow speed and short cable lengths.
High-density 50-pin connector: The high-density 50-pin connector is used on scanners and Jaz drives. It is one of the more common SCSI connectors and is usually used to connect SCSI-2 devices. Both ends of the cable are usually 50-pin male, while the sockets on the host adapter and external devices are 50-pin female.
DB 25-pin connector: The DB 25-pin or D Sub 25 is by far the most widely used connector. This connector is used for parallel and serial printers in addition to the many other devices available. Both ends of the cable are usually 25-pin male, while the sockets on the host adapter and external devices are 25-pin female. This cable is almost always an external connector.
Note: DB-25 SCSI CABLES are not compatible with and should not be used as serial or printer cables; serial cables and printer cables should not be used or attached to DB-25 SCSI adapters. You can short out the SCSI host adapter or the motherboard by using the wrong cable. Marking cables is the best way to avoid this.
IDC50 connector: The IDC50 is the most common internal SCSI connector. It is very similar to the standard IDE internal ribbon cable. The IDC50 SCSI cable is considerably wider then an IDE ribbon cable; in fact, it is usually the widest standard internal cable in use. This is a standard SCSI-2 10MBps internal SCSI cable. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often expensive and require a large case, as the cables may be four or five feet long.
High-density 68-pin connector: The high-density 68-pin connector is the SCSI connector of choice for SCSI-3 host adapters and peripherals. There is an internal ribbon cable version that looks very similar to the IDC50 connector. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often very expensive and require a large case, as the cables may be three or more feet long. Both ends of the external cable are usually 68-pin male, while the sockets on the host adapter and external devices are 68-pin female.
SCA 80-pin Micro-Centronics connector: SCA stands for Single Connector Attachment, a type of disk drive connector that includes connection pins for the power cables as well as the data wires. A SCA connector uses an 80-pin plug and socket to connect peripherals. This connector combines power, data channel, and ID configuration for fast installation and removal. SCA connectors are typically found only on high-end SCSI hard disks. The SCA interface was designed to provide a standard connection for systems using drives that can be hot-swapped. SCA makes swapping SCSI hard drives much easier than with traditional SCSI cables, plugs, and sockets. An adapter enables SCA drives to fit into standard SCSI enclosures.
SCSI SFF 8482: Also called "4x internal" by some vendors. This is a connector with the same form factor as SATA with the addition of a "bump" to key it specifically for SAS. (SATA drives can be plugged into SAS controllers, but SAS drives will not function with a SATA controller; hence, the necessity for the key bump on the connector.) As the name says, it's meant to be used internally, i.e., inside the computer case.
SCSI SFF 8484: Also called "32-pin" or "MultiLane". This is a high density connector usually intended to plug into the motherboard, controller, or backplane itself. Cables with this connector on one end usually have four individual SFF 8482 connectors on the other.
Serial Attached SCSI SFF 8470: Also called "4x external" by some vendors. This is simply a version of the SFF 8484 that's meant to be used with external (i.e., not located within the case) drives.
