Question 3: What does double label mean in electrical equipment? In power system (power plant, substation), in order to strengthen safety management and prevent misoperation accidents, double (name+number) numbers are applied to equipment.

Example of double numbering: 2553 switch of floating 20kv ballast line, which is the name and number of a line switch (circuit breaker). "220kv vibrating wire" is the name and "2553" is the number.

Another example is: 220kv primary bus voltage transformer 2530 1 switch, which is the 220kv primary bus voltage transformer switch, and 2530 1 is its number.

Another example: No.7 main transformer neutral point 25070 switch knife, this is the neutral point grounding switch knife of No.7 main transformer, and 25070 is its serial number.

It is stipulated that the power system switching operation ticket must be filled with double numbers, and the double numbers should be checked during field operation, which greatly reduces the probability of "wrong interval" and "wrong pull and wrong connection".

Question: What do you mean by running even numbers in 35Kv substation? The double number represents the equipment number and equipment name, which is used for ticket making or operation. When handling the working ticket or operation ticket, the corresponding equipment number and equipment name should be stated, such as DL-30 1 (equipment number) and new yellow line circuit breaker (equipment name). This is an important measure to prevent misoperation.

Question 5: What is Apple ID dual authentication? What's the difference between two-step authentication and two-step authentication? First of all, we need to clarify a concept: "double authentication" is not "two-step authentication".

The difference between "double authentication" and "two-step authentication"

Although the two verification methods are basically the same in principle, there are still significant differences in specific implementation methods.

1. Close

"Two-step authentication" can only be enabled on the management page of Apple ID.

"Double Authentication" can only be opened on the iCloud account management page of iOS 9.3 or OSX10.11.4.

2. Equipment registration method

When two-step verification is enabled, the system will ask you to send the verification code to each iOS device enabled with Find My iPhone, so that the corresponding device can be set as a trusted device and used to receive the verification code.

When Double Authentication is enabled, the system will automatically set all devices registered in iCloud as "trusted devices".

Both methods require manual verification of trusted phone numbers.

Step 3 get the key back

"Two-step authentication" will generate a series of "recovery keys" as a backup means to restore account access rights.

Two-factor authentication does not generate any recovery keys.

4. Verification process

When logging in Apple ID on an untrusted device or browser, both authentication methods require an additional verification code to confirm the identity.

After entering the account password, Two-Step Authentication will ask you to select a trusted device or a trusted phone number to receive a series of four-digit verification codes.

"Double Authentication" will automatically send login reminders to all trusted devices, or you can manually choose to use your mobile phone number to receive the verification code. Different from the "two-step verification", the login reminder not only contains the verification code, but also shows the approximate geographical location of the account login, and the length of the verification code has also expanded from four to six.

Users can choose whether to allow login attempts on any device. If "Allow" is selected, the system will automatically display a six-digit verification code, otherwise, the login will be directly refused. After selecting on one device, the login reminders on other devices will automatically disappear.

5. Device receiving verification code

Two-step verification can only send verification code to iOS devices.

"Double Authentication" can send verification codes to iOS devices and Macs.

6. Use offline

When all trusted devices and trusted phone numbers are offline, two-step authentication will not be available, which may cause trouble for your login.

And "double authentication" can generate verification code offline on "trusted devices", which greatly simplifies the user experience.

If you want to log in to Apple ID on devices before iOS 9 and OS X El Capitan, you need to manually generate a verification code, and enter the account password in the password field of the old device, followed by the generated six-digit verification code.

7. Change of safety information

When Two-Step Authentication is enabled, you can only modify the security information in the Apple ID, including Trusted Devices.

"Double Authentication" allows you to modify the account management page directly on the device side.

8. Handling after forgetting the password

"Two-step authentication" requires you to have any two of account password, recovery key and a "trusted device" that can receive verification code to access Apple ID. Once you lose any two of these three things, you will lose access to your Apple ID forever.

Two-factor authentication has no recovery key. When you forget your password, you can't use trusted devices and trusted phone numbers, you can also use account recovery and submit relevant information to Apple for review in an attempt to re-access your account. Apple technical support has no right to interfere with the process of "account recovery", which has put an end to "internal ghosts" to some extent. ...& gt& gt
