JOB APPLICATION
Definition
From the employer's perspective, the application serves a number of purposes. These vary depending on the nature of the job and the preferences of the person responsible for hiring, as "each organization should have an application form that reflects its own environment. At a minimum, an application usually requires the applicant to provide information sufficient to demonstrate that he or she is legally permitted to be employed. The typical application also requires the applicant to provide information regarding relevant skillseducation, and experience (previous employment or volunteer work). The application itself is a minor test of the applicant's literacypenmanship, and communication skills - a careless job applicant might disqualify themselves with a poorly filled-out application.

Definition Contactor

Definition Contactor
 Nama:Ilham Noer Nasution/1620201090

The concept for DP contactors and starters originated in the 1950s at the request of several large HVAC OEMs. A contactor is an electrically controlled switch used for switching an electrical power circuit, similar to relay except with higher current ratings. A contactor is controlled by a circuit which has a much lower power level than the switched circuit.
Contactors come in many forms with varying capacities and features. Unlike a circuit breaker, a contactor is not intended to interrupt a short ciruiit current. Contactors range from those having a breaking current of several amperes to thousands of amperes and 24 V DC to many kilovolts. The physical size of contactors ranges from a device small enough to pick up with one hand, to large devices approximately a meter on a side.
Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads. A contactor has three components. The contacts are the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. The electromagnet (or "coil") provides the driving force to close the contacts.
The enclosure is a frame housing the contact and the electromagnet. Enclosures are made of insulating materials like Bakelite, Nylon 6, and thermosetting plastics to protect and insulate the contacts and to provide some measure of protection against personnel touching the contacts. Open-frame contactors may have a further enclosure to protect against dust, oil, explosion hazards and weather.NO (Normally Open) on the contactor is located in the coil number 13 and 14 , while NC(Normally Close) is located in the coil number 21 and 22.
Magnetic blowouts use blowout coils to lengthen and move the electric arc. These are especially useful in DC power circuits. AC arcs have periods of low current, during which the arc can be extinguished with relative ease, but DC arcs have continuous high current, so blowing them out requires the arc to be stretched further than an AC arc of the same current. The magnetic blowouts in the pictured Albright contactor (which is designed for DC currents) more than double the current it can break, increasing it from 600 A to 1,500 A.
Sometimes an economizer circuit is also installed to reduce the power required to keep a contactor closed; an auxiliary contact reduces coil current after the contactor closessomewhat greater amount of power is required to initially close a contactor than is required to keep it closed. Such a circuit can save a substantial amount of power and allow the energized coil to stay cooler. Economizer circuits are nearly always applied on direct-current contactor coils and on large alternating current contactor coils.
A basic contactor will have a coil input (which may be driven by either an AC or DC supply depending on the contactor design). The coil may be energized at the same voltage as a motor the contactor is controlling, or may be separately controlled with a lower coil voltage better suited to control by programmable controllers and lower-voltage pilot devices. Certain contactors have series coils connected in the motor circuit; these are used, for example, for automatic acceleration control, where the next stage of resistance is not cut out until the motor current has dropped.

Konsep untuk kontaktor DP dan pemula berasal dari tahun 1950-an atas permintaan beberapa OEM HVAC besar. Sebuah kontaktor adalah sebuah saklar yang dikendalikan secara elektrik digunakan untuk beralih sirkuit listrik, mirip dengan relay kecuali dengan penilaian saat ini lebih tinggi. Sebuah kontaktor dikendalikan oleh sebuah sirkuit yang memiliki tingkat daya yang jauh lebih rendah daripada circuit switched.
Kontaktor datang dalam berbagai bentuk dengan berbagai kapasitas dan fitur. Tidak seperti pemutus sirkuit, kontaktor tidak dimaksudkan untuk mengganggu hubungan pendek arus. Kontaktor berkisar dari mereka yang memiliki arus melanggar beberapa ampere ke ribuan ampere dan 24 V DC ke banyak kilovolt. Ukuran fisik kontaktor berkisar dari perangkat yang cukup kecil untuk mengambil dengan satu tangan, untuk perangkat besar sekitar satu meter di sisi.
Kontaktor yang digunakan untuk mengontrol motor listrik, pencahayaan, pemanasan, kapasitor bank, evaporator termal, dan beban listrik lainnya.
Sebuah kontaktor memiliki tiga komponen. Kontak adalah membawa bagian saat kontaktor. Ini termasuk kontak listrik, kontak bantu, dan kontak mata. Elektromagnet (atau "coil") memberikan kekuatan pendorong untuk menutup kontak. kandang adalah bingkai perumahan kontak dan elektromagnet. Kandang terbuat dari bahan isolasi seperti Bakelite, Nylon 6, dan thermosetting plastik untuk melindungi dan mengisolasi kontak dan untuk menyediakan beberapa ukuran perlindungan terhadap personil menyentuh kontak. Terbuka-frame kontaktor mungkin memiliki kandang lebih lanjut untuk melindungi terhadap debu, minyak, bahaya ledakan dan cuaca
. letak NO pada kontaktor terletak di nomor koil 13 dan 14 sedangkan koil NC berada di nomor koil 21 dan 22ledakan gas magnetik menggunakan kumparan ledakan untuk memperpanjang dan memindahkan busur listrik. Ini sangat berguna dalam sirkuit listrik DC.busur AC memiliki periode rendah saat ini, di mana busur dapat dipadamkan dengan relatif mudah, tetapi DC busur memiliki arus tinggi terus menerus, sehingga meniup mereka keluar membutuhkan busur yang akan membentang lebih jauh dari busur AC dari arus yang sama. The ledakan gas magnetik di kontaktor Albright yang digambarkan (yang dirancang untuk arus DC) lebih dari dua kali lipat saat itu dapat mematahkan, meningkat dari 600 A sampai 1.500 A.
Kadang-kadang sirkuit economizer juga dipasang untuk mengurangi daya yang diperlukan untuk menjaga kontaktor ditutup; kontak bantu mengurangi coil saat setelah kontaktor menutup. Sebuah jumlah yang agak lebih besar dari daya yang dibutuhkan untuk awalnya menutup kontaktor dari yang dibutuhkan untuk tetap ditutup. sirkuit tersebut dapat menyimpan sejumlah besar kekuasaan dan memungkinkan kumparan energi untuk tetap dingin. sirkuit economizer hampir selalu diterapkan pada kumparan kontaktor arus searah dan bolak besar kumparan kontaktor saat ini.
Sebuah kontaktor dasar akan memiliki masukan coil (yang mungkin didorong oleh baik pasokan AC atau DC tergantung pada desain kontaktor). kumparan dapat diberi energi pada tegangan yang sama sebagai motor kontaktor mengendalikan, atau dapat dikontrol secara terpisah dengan tegangan koil yang lebih rendah lebih cocok untuk mengontrol oleh pengendali programmable dan perangkat pilot tegangan rendah. kontaktor tertentu memiliki kumparan terhubung seri di sirkuit motor; ini digunakan, misalnya, untuk kontrol percepatan otomatis, di mana tahap berikutnya resistance tidak dipotong sampai saat ini motor telah turun.
