Q:How to use the capacitor to test whether the wire is broken
The cable tray will heat up, and it will do so because the disk will lead to heat accumulation, which will affect the heat dissipation and will burn the wire in a serious way. Especially when the maximum current carrying capacity of the wire is more obvious, the wire tray is used up Can not exceed the rated capacity of more than 1/2 "inside the two lines of the current direction at any time can be offset each other to produce the electromagnetic effect" This is very right, the use of wire tray will not increase the wire impedance, But can not be a single wire, must be the same circuit with two at the same time disk up
Q:I would like to know the power cord plug the production process, the equipment used, the details better. Thank you!
The amplifier is connected to the speaker cable, and the other parts are connected using an audio signal cable (microphone cable). Audio signal line also known as the microphone line, you can use the lotus head, Cannon head, big Samsung, and other different connector connection. Audio signal line refers to the kind of input and output balance signal with a shielded signal line (usually replaced by a microphone cable) to connect the front and power amplifier, balanced line. It is used to transmit the signal, is the carrier of the signal. It transmits signals in two distinct ways. The cable itself can transmit signals, or the cable can transmit the energy emitted by the external signal source. Speaker line for connecting the amplifier and speakers, which flow the current signal is much larger than the video cable and audio lines mentioned above, because the signal amplitude is very large, this line is often no shield, for this wire, the key is to reduce Its resistance, because the output impedance of modern amplifier is very low, so the requirements of the speaker line also increased, such as the use of large cross-sectional area or stranded strand.
Q:Mac off the machine, I press the power button, off is off, what is no longer open it!
Do you install the trough on the inside of the door? The wires are used to connect the indicator lights on the panel, control switches, control buttons, meters and the like. Then the panel should be done before the factory, the sink groove material is plastic or nylon, glue is useless, in the electrical inside the method with glue is not feasible, can only be screwed, in order to Do not damage the image of the panel, the inside of the panel should be welded, spot welding a few pieces of connection, used to fix the sink slot.
Q:What is the difference between YC and YZ cable?
KVV Control Cable: Hard Conductor, Class 1 and Category 2 Conductor Voltage 450 / 750vRVV Flexible Cable: Soft Conductor, Category 5 and Category 6 Conductor Voltage 300 / 500V
Q:Will the installation of the socket and switch what are the requirements? How should the wire tube be discharged?
10-core PVC with shielded soft sheathed cable, each two is a group of (twisted pair), a total of five groups
Q:AMP 24 port patch panel line order 568A and 568B what
If the cable is shorter about 1 meter, then 2.5 pure copper wire is enough, long to use 4 square
Q:On the same ditch laying high and low voltage cable doubts?
PVC pipe 6 points of course, more than 4 points in large, the score is in English, every 8 points is 1 inch, equal to 25.4mm, it represents the pipe diameter. 4 points corresponding to the tube diameter of .6 points corresponding to the tube diameter of .1 inches corresponding pipe diameter of 32. PVC type pipe with PVC pipe with PVC pipe has PVC electric tube JG / T3050-1998PVC electrical casing classification, divided into L type (light) M type (medium) H type (heavy) First, the implementation of standards: JG / T3050-1998 Second, the product specifications: divided into light -. medium -. heavy-type -405 three. . light -205 outside diameter ¢ 16mm- ¢ 50mm. medium -305 outside diameter ¢ 16mm- ¢ 50mm. heavy -405 diameter ¢ 16mm- ¢ 50mm Third, the nominal diameter were: .... . the thickness of the product is as follows: .16 outside the light, medium and heavy thickness were: 1.00 (light, allowable difference +0.15), 1.20 (allowable difference +0.3), 1.6 (weight, allowable difference +0.3) The The medium and heavy (no light) thickness of the outer diameter of .20 are: 1.25 (medium, allowable +0.3), 1.8 (weight, allowable difference +0.3). .25 outside the diameter of the weight (no light) thickness were: 1.50 (in the allowable difference +0.3), 1.9 (weight, allowable difference +0.3). The light, medium and heavy thickness of the outer diameter of .32 are: 1.40 (light, allowable difference +0.3), 1.80 (medium, allowable +0.3), 2.4 (weight, allowable difference +0.3). .40 outside the light, medium and heavy thickness were: 1.80 (light, medium, allow the difference +0.3), 2.0 (weight, allowable difference +0.3). Fourth, the national standard wall thickness 16: I20: 1.125; 1.332: 1.540: 1.950: 2.263; 2.7 These are more commonly used.
Q:Cpu power supply line is not long enough to meet the heat sink, a map, how to solve?
The distinction between special and non-specific depends on the nature of the load. Green line from the substation dedicated to the user, only for the user, do not accept the public network overhaul maintenance and power outages, also said that as long as the nearest substation power you have electricity; non-green as the public line. But now power supply reliability is so high, the city network are using ring network, the probability of power failure is small, not to mention you are using a dual power line, power failure is smaller, unless the area power outage. But you also have an important load on their own generators, so non-particularly important load, double power enough to meet its power supply needs.
Q:TC line and SC line tube What is the difference
The rated voltage of the power cable is generally 06 / 1kV and above, the control cable is mainly 450 / 750V The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick First, the control cable belongs to the electrical equipment cable, and the power cable is the cable five categories in the two The standard for the control cable is the standard of the power cable is the color of the insulated wire core of the GB control cable is generally black and white, and the low voltage of the power cable is generally separated Control cable cross-section is generally not more than 10 square feet, the power cable is mainly the transmission of electricity, are generally large cross-section As mentioned above, the specifications of the power cable in general can be larger, as large as 500 square feet (conventional manufacturers can produce the range), and then a large cross-section can do the manufacturers to be relatively less, and control the cable cross-section in general Smaller, maximum no more than 10 square feet From the cable core number, the power cable according to the power grid requirements, up to the general 5 core, and control cable transmission control signal, the core number is more, according to the standard more than 61 core, but also can be produced according to user requirements The
Q:Will my TV light be on, but the screen does not show up. Will the general is that there is a problem? The
1 mouth connected graphics card (with the transfer cable), 2 port drive 4 and 5 were connected to two hard drives, 3 connected to the power switch motherboard there is a 4pin for the graphics card power supply ?? This is not try, the video card is not Independent of the . the above has been said to use the adapter cable power supply, and a 3850 does not require dual power supply 3 connected to the power switch is also very strange, how there are power switch it ... if necessary on the connection, if not long , With the transfer line as the extension line connected to the line, in fact, as long as the quality of the adapter, no problem, are the same use, the power consumption of the hard disk is very small, the most power is that video card, optical drive standby The time is not how the electricity, under normal circumstances CD-ROM are not at work
