The development of circuit breaker construction is as follows:<\/p>\n

a. Disconnect power from the air<\/strong>
\nTapered shape, the electric arc will arise (jump) in the first tapered portion at the time of the switch contacts separate. Because the specific gravity of the electric arc is smaller than the density of air, electric arc will float to the top so that the electric arc elongated and eventually drop out. Figure II.37 shows the air circuit breaker.<\/p>\n<\/div>\n

b. breaker force many oil<\/strong>
\nCircuit breaker (PMT) many oil or bulk oil circuit breakers. In this type of PMT, switch contacts immersed in oil. Oil serves as a medium breaker electric arc. Put oil in the tank so that the construction of the circuit breaker oil into a large lot. Figure II.38 shows the construction area oil outage PMT much simpler.<\/div>\n

c. breaker little oil power<\/strong>
\nCircuit breaker (PMT) oil content ataulow little oil circuit breaker. Media breaker arc is used as the PMT oil much oil, it’s just a little oil on the PMT PMT is no part that produces pressurized oil to be sprayed on the electric arc, either at the time of the PMT PMT opened and closed on time.<\/p>\n
Because it uses oil pressure, oil PMT dimensions slightly smaller than the dimensions of many oil PMT. In a little oil PMT, the PMT oil quality should be closely monitored, especially after the PMT work due to interference.<\/p>\n
At the time of the arc cut off due to fault current, electric arc spraying oil because the disorder will experience greater carbonization.
\nCarbon is no insulation, so it should be the replacement of the PMT oil when oil is already visible due to black carbon.
\nIn addition to relying on oil spraying to break the electrical arc occurs, lengthen the electric arc technique is also used in this way, ie by sharpening the contact form male and female contacts.<\/p>\n

d. breaker SF6 gas power<\/strong>
\nCircuit breaker (PMT) gas SF6 working principle is similar to the working principle PMT little oil, the difference lies in the media breaker arc used, the SF6 gas. SF6 gas has excellent insulating properties besides sifamya as well as heat. In PMT SF6 gas sealing problems arise between the PMT moving with the silence of the gas can penetrate (leak) between the two parts rub against each other so that the necessary seals (sealing) the good in order to minimize leakage of SF6 gas.<\/p>\n
In PMT SF6 gas, gas pressure gauge fitted so visible if the SF6 gas pressure is reduced and the necessary back filling SF6 gas. Compared with a little oil PMT, the PMT SF6 gas has dimensions roughly similar but easier maintenance.<\/p>\n
e. Breaker Power vacuum<\/strong>
\nCircuit breaker (PMT) is a vacuum PMT using cutting-edge technology. In no media PMT vacuum breaker disconnects the electric arc and electric arc technique in a vacuum PMT depends electric arc extending techniques. Implementation extend electric arc done by making various forms of contacts and each plant has its contact forms, respectively.<\/p>\n
Unlike the PMT SF6 gas, if there is a leak in the vacuum PMT, then it can not be done “charging” again because the process of creating a vacuum can not be done in the field and undesirable leakage that can reduce the value of the vacuum. Construction PMT vacuum to avoid any air gap so that the shift of moving parts with part fixed (static) could cause an air gap can be avoided and instead used the wave-shaped flexible metal that can be extended and shortened.<\/p>\n
f. breaker Power Magnetic Field<\/strong>
\nCircuit breaker (PMT) magnetic field or magnetic circuit breaker has such working principle of air PMT, only here there is a magnet that generates a magnetic field which serves to draw arcs that arise during the opening of the PMT so that the bus, electricity becomes longer and eventually drop out. Figure II.55 PMT magnetic field.<\/div>\n

g. breaker Power Compressed Air<\/strong>
\nCircuit breaker (PMT) in English compressed air blast circuit breaker is called water. This type of PMT has a similar principle to the working principle of SF6 gas PMT PMT only on compressed air into the media breaker electric arc is compressed air. Because the insulating ability of the air is lower than the ability of SF6 gas insulation, then the PMT compressed air required air pressure greater than the pressure of SF6 gas in the PMT SF6 gas, to obtain the desired air pressure in the compressed air PMT, compressor wear. This is not favorable due to its price PMT becomes more expensive.<\/p>\n","protected":false},"excerpt":{"rendered":"
