Light is an object that can turn off light and heat energy needs. of course the lights have a limited lifespan and will break in fast and slow tempos. Here are some tips that may be useful to you in connection with the light bulb:
1. Turn off electricity
Electric shock that you do not you should make sure first that the light switch in the off state.
2. Broken lamps
Use fruits or vegetables are hard to be stabbed into the lamp is broken so easily rotated to be removed from its place.
3. substitute light
Do not send children to replace the existing lights on the ceiling as if the joke could be dangerous shock or a fall.
4. Stairs or a Strong Footing
Make sure stairs are strong and not by or rocking back and forth. Better to use a stronger foothold as a bench or table. Falling from a height of one or two feet can cause a fatal accident.
5. Dry hands
Our hands are not wet or hit the water and should wear footwear that is too dry when replacing the lamp.
6. Qualified bulbs
Use a light quality that are not easily damaged and durable. That way we do not have to change lamps often. Saving energy also has become imperative all of us, because our country is an electric energy crisis. If the electrical load is maximum, then do pln is rotating blackouts are of course very disturbing comfort us who are familiar with furniture and appliances that use electricity.
"Proximity sensor" includes all sensors that perform sensing / detection in non-contact, compared with a sensor, such as limit switches, which detect objects by physical contact. Proximity Sensors convert information about the movement or presence of an object into an electrical signal. There are three types of detection systems that perform this conversion: a system using eddy currents generated in the metal object by electromagnetic induction sensing system that detects changes in electrical capacity when sensing object approaching, and a system that uses magnets and reed switches.
Japanese Industrial Standard (JIS) defines a proximity sensor in JIS C 8201-5-2 (low voltage switch gear and control gear, Part 5: Control circuit devices and switching elements, Part 2: Proximity sensor), in accordance with IEC 60947-5 -2 translation of non-contact detection switch positions.
JIS provides the common name "proximity sensor" for all sensors that provide non-contact detection of target objects that are near or within the vicinity of the sensor, and classify them as inductive, capacitive, ultrasonic, photoelectric, magnetic, etc.
Technical guidelines define all inductive sensors are used to detect metallic objects, capacitive sensors are used to detect metal objects as well as non-metallic, and magnetic field sensor utilizing DC as a Proximity Sensor.
What is a Motor? motor
or not here is not the same as the existing motor highway street who
love racing and dangerous people, here is the motor is an electric
motor, which can move the machine so the machine can run and can
produce something useful buatorang many, if ordinary people layman said anyway .. name dynamo, there is a similarity because both use a coil of wire.
. Motor
in Indonesian means "driving" something that can move the resulting
activity but, in principle, work definition of motors is a tool that
converts electrical energy into rotary motion energy or energy, at the
time of the motor coil is electrified it on the rotor will occur style rotate so as to produce round, this round which will move the load as a propeller fan, water pump, gear box etc..
. The
world's motor industry is to play a role because the average production
is driven by motor engines motors then this will move the gears,
conveyors, baling2, pumps, vibrator, etc..
The main parts of the motor there are some very important components, namely,
1. Statorthe form of a coil of wire wrapped around in such a way that the email function to generate a magnetic field when electrified.
2.Rotorsteel shaft that has a coil of wire in it, serves to channel the rotor turning force to the load.
3.Bearing/bantalanserves
to hold the rotor to rotate on its axis with the stable, the number of
bearings in the motor there are two pieces, lying on the front and rear.
4.Fan/kipasbody
works to cool the motor so that its temperature is maintained, located
at the back of the motor, the motor temperature to rise slowly with
respect to the presence of a considerable burden and the use of a long
5.Bodyserves
as a container of all the motor that has been mentioned above, made of
iron and finned-fins that serve as cooling air flow throughout the body
and motor.
What is a fuse?, Fuses or fuse is a device that can decide the flow of electricity in the event of short circuit (short) or an excess current (over current) in electrical circuits, or other expenses, such as vehicles, home installation, electronic circuits etc.. There are many types of fuse / fuse yet in common use among the people is the type of fuse glass, made of glass or glass, in which there is a special piece of wire, the wire cross section determines the size of the fuse capacity or flow of electric current fuse capability.
How can fuse to prevent fires .. ?
. When the electrical circuit that we use on vehicles such as cars, motor homes or in electrical circuits and electronic circuits occur short circuit / short-circuit, the electric current flowing in the circuit will be larger, thus causing the cable conductor of heat, if this situation lasts longer, the cable will burn and burn the material that is around a combustible such as wood, paper, plastic, etc..
. With a fuse attached to the electrical circuit, then the fire will be avoided, why?, Because when the short circuit occurs in electrical circuits, then within a trillionth of a second electric current will be cut off quickly, so that the conductor of the cable is not the case of excessive heat and fire were can be avoided. In addition it also serves to secure the fuse electrical circuit or other equipment from the damaging effects of excessive currents.
How to know the capacity of the fuse.
. The capacity of the fuse can be seen on the body, there are listed a number that indicates the capacity of, for example F3A 250V or 250V F5A etc.. This means that the voltage is allowed to flow through the fuse is a maximum of 250 volts and a maximum electric current at 5 amperes, if the electric current and voltage flowing above that value, then the fuse will be disconnected.
Conductors are materials that can easily conduct electricity so that the conductor is often referred to as a good conductor of electricity. On a good conductor, the number of free electrons, the electrons that have a large enough energy (located at the outermost track) is banyakdan free to move, eg in copper materials, each copper atom contributes one free electron.
Copper as a substance that has the atomic number 29, has a free electron in charge of this terluarnya.elektron skin to conduct electricity when the conductor of the rated voltage
Conductor in electronics engineering is a substance that can conduct electrical current, either solid, liquid or gas. Because it is conductive, it is called a conductor. A good conductor has a small resistivity. Conductors are materials that are very good ability to conduct electricity, almost all metals are metallic conductors.
examples of several types of conductors
Examples of conductors include gold, silver, copper, aluminum, zinc, iron successively growing resistance, type. So as gold is a very good conductor, but because it is very expensive price, the economically copper and aluminum are the most widely used
Multimeter is a measurement tool used to measure electric voltage, electric current, and resistance (resistance). It is a general sense multimeter, while thhttp://www.blogger.com/blogger.g?blogID=6770520836530401260#editor/target=post;postID=9209447304009896842e development multimeter can still be used for several functions such as measuring temperature, inductance, frequency, and so forth. There are also people who mention the multimeter as AVO meter, presumably A (ampere), V (volts), and O (ohm).
Multimeter is divided into two types: analog multimeter and digital multimeter.
analog multimeter
Analog multimeter is more widely used for everyday use, such as the TV or computer repairman mostly use the analog of this type. The surplus is easy reading with a more simple. While weakness is a low accuracy, so for measurements requiring high precision digital multimeter should be used.
digital multimeter
Digital multimeter has high accuracy, and usability more than the analog multimeter. Which has an extra-extra units more closely, and also measurements more options, not limited to the ampere, volt and ohm it. Digital multimeter is usually used in research or work that requires high accuracy measure, but now many computer repair shops and service centers that use a digital multimeter. The drawback is difficult to monitor the voltage is not stable. So when making voltage measurements that moves up and down, you should use an analog multimeter.
MCB works by layoffs caused by the flow of electricity over the use of electromagnet / bimetal. MCB workings of this is to utilize the heat expansion of the bimetallic effect to determine the current flowing electric current. MCB capacity in units of Amperes (A), capacity MCB from 1A, 2A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, etc.. MCB is used must have the SNI logo on the MCB
How to know the maximum power of the MCB is by multiplying the capacity of the MCB with 220v (voltage common in Indonesia).
example
6A MCB had the capacity to withstand the power of:
6A x 220v = 1200 Watts
Some usability MCB:
1. Limiting Use of Electricity
2. Turn off power when a short circuit occurs (shorted)
3. Securing Electrical Installation
4. Divide the house into some electrical parts, making it easier to detect damage to electrical installations
How to determine the cause of MCB fall
how to touch the white part of the MCB, whether hot or not.
A. If not hot,
there is the possibility of installing a shorting, shorting is usually when the installation who has improved, the MCB can be switched directly. If after a few minutes MCB is still not start again, meaning that the MCB is damaged
A. if the heat
MCB indicates that excess weight in a long time, wait several minutes just to turn on the MCB, usually when directly in turn, MCB will go down again, this is caused by a bimetal which expands and takes time to get back into shape. If after a few minutes, the MCB is still not start, meaning that the MCB is damaged
