No battery time swith AC220V TB-38

Q:There are the same period, these three parameters on behalf of what?: 1, on the on-load tap-changer refers to the same period refers to the same period (different from the same period of multi-fracture), that is, the difference between the maximum and minimum, different brands of tap-changer performance indicators are different, but The same period generally requires a few ms. Part of the on-load tap-changer tester only switch time display, the same period of data need their own calculation.

Q:For example, I use the IGBT circuit switch, using the same gate resistance and drive circuit. Then use it to make a normal working current only 1A off the external circuit off time And let a current up to 100A of the external circuit completely off the turn-off time, Will there be a big difference between the two times? Or that depends entirely on the drive part of the control of the gate G, CE voltage at both ends of the voltage is not much relationship?: Switch with IGBT, the switch time with the load current size does not matter. IGBT can not control the size of the current, IGBT is only a switching device, when connected to the circuit, used to control the circuit off time. IGBT and inductance together to achieve the control of the current. Take the voltage source as an example, only consider the main circuit, voltage source, IGBT, inductance, load series, when the IGBT is turned off, the power and inductance disconnected from the inductor to the load power supply, the inductor current can not be changed, but will decline. When the IGBT is turned on, the power supply and inductance connected to the power supply to the inductor and load power supply, the inductor current can not be mutated, but will rise. The current in the inductor and the rise of how much, by the IGBT turn off and open the time to determine, that is the IGBT turn on and off the law determines the law of the current changes in the inductor, also said that the realization of the current control.

Q:Air conditioning short time switch it all right: How is it called a short time switch? Just opened, and closed it?

Q:The most common switching circuit Ton-turn-on time open Toff-turn-off time off Ts-storage time Tf-fall time Tr-rise time Td-delay time: Transistor in the switch circuit in the open and closed, due to the existence of barrier voltage, will produce a certain time delay. Storage, rise, fall mainly produce some cross-distortion, so that the circuit load of electricity becomes unstable ... ...

Q:Microcomputer time control switch how to adjust the time: 2.6 When connected to the power supply, the green light on the panel indicates that the circuit is energized and the traffic light is on to indicate that the switch is on. 2.7 Press the "Auto / Manual" button to open or close the circuit directly. To make the switch automatic, press the "AUTO / MANUAL" key to change the "▼" symbol below the display to the "OFF" position, then press Press this key to the "automatic" position For example: every night 18:30 automatically open, according to the above 2 points set as shown in Figure 3, every night 23:20 automatically shut down, according to the above 3 points set as shown in Figure 4 , According to the fourth point of debugging on the LCD (2 open, 2 off ... 10 open, 10 off) is displayed as "-: -" pattern, then press the 6th point, 7:00 to operate.

Q:When to install the switch socket? Is that brand better?: Socket switch is very important, must go to the store to buy To be particularly safe and reliable, the preferred NVC and Philips it, cheap goods do not buy, electricity is not trouble Good switch socket can see a look, from the thickness of the hardness of a touch on the feeling of a great gap Especially in the building materials market that kind of cheap goods, generally do not buy Their own spend more than a few dollars, peace of mind The method of installation First to buy socket switch embedded parts, is embedded in the tin, the wire head hidden in the tin box, to protect And then wait for the completion of woodworking, the switch panel or socket panel and tin inside the wire head connected firmly, the connection is red and yellow blue and white lines, respectively, on behalf of the line of fire, the bottom line and the zero line, connecting the first eight gate Off on the line Finally, the embedded iron box with screws and panels fixed on the line (tin is the first to buy, with a screw on the top ) Is not directly fixed on the wall of Kazakhstan, is the first embedded in the wall a box

Q:For example, I hope that at some time the computer is unable to boot, unless there is an administrator password. Or at a certain point in time to shut down, is mandatory. How to operate, or what software to download? Please heroes pointing to help!: Shutdown.exe parameters, each with a specific purpose, the implementation of each will have a different effect, such as "-s" means that the closure of the local computer, "- a" that cancel the shutdown operation, the following list of more parameters , We can use in Shutdown.exe on demand. -f: Forcibly closes the application -m \ computer name: controls the remote computer -i: Displays the graphical user interface, but must be the first option for Shutdown -l: Log out of current user -r: Shutdown and reboot -t time: set the shutdown countdown -c "message content": enter the message content in the shutdown dialog box (can not exceed 127 characters) In addition, you can also find third-party software on the Internet to control

Q:Transistor 8050 do switch circuit response time how long, zero a few seconds?: The switching speed is determined by the entire circuit. Not to say that the transistor itself is how much, this circuit is how much. Such as the delay circuit, you can let the signal after a few seconds to let the transistor action, or a few minutes, a few hours, a few ... ... only action.

Q:Time timer switch time timer switch: The timer is really a great invention, so that a lot of people need to control the time to work a lot easier. People even use the timer in the military, made a time bomb, regular detonator. Many household appliances are now equipped with a timer to control the switch or working hours.

Q:How to adjust the time for the bells: Hello, time control switch settings are relatively simple, Such as setting the load for an open time 18:00, The time is 05:00
