What are the main components of switchgear?
Components. A switchgear assembly has two types of components: Power-conducting components, such as switches, circuit breakers, fuses, and lightning arrestors, that conduct or interrupt the flow of electrical power.
What is switchgear and its components?
Switchgear essentially consists of switching and protecting devices such as switches, fuses, isolators, circuit breakers, protective relays, control panels, lightning arrestors, current transformers, potential transformers, auto reclosures, and various associated equipment.
What is considered high voltage switchgear?
The power system deals with voltage above 36KV, is referred as high voltage switchgear. As the voltage level is high the arcing produced during switching operation is also very high.
What is high voltage switchgear used for?
What is Switchgear? Electrical Switchgear is connected to electric supply systems and is used in both low and high voltage power transformers. Its purpose is to de-energise set up for maintenance and repair to correct the faulty issues.
What is a medium voltage switchgear?
Eaton’s medium-voltage switchgear provides centralized control and protection of medium-voltage power equipment and circuits in industrial, commercial, and utility installations involving generators, motors, feeder circuits, and transmission and distribution lines.
What is a low voltage switchgear?
Low-voltage switchgear provides short-circuit and overload protection via low-voltage power circuit breakers (LV-PCB) with integral trip units. These low-voltage circuit breakers are typically through-the-door, draw-out devices.
What are the features of high voltage switchgear?
High Voltage Switchgear. 1 Air Blast Circuit Breaker. In this design, a blast of high pressure compressed air is used to quench arc between two detaching contacts, when the arc 2 Oil Circuit Breaker. 3 SF 6 Circuit Breaker. 4 Vacuum Circuit Breaker. 5 Essential Features of High Voltage Circuit Breaker.
What type of circuit breaker is used for high voltage switchgear?
Minimum oil circuit breaker ( MOCB ), air blast circuit breaker and SF 6 circuit breaker are mostly used for high voltage switchgear. Vacuum circuit breaker is rarely used for this purpose as till date vacuum technology is not adequate for interrupting very high voltage short circuit current.
What are the precautions to be taken while designing high voltage switchgear?
So, special care is to be taken during the designing of high voltage switchgear. High voltage circuit breaker, is the main component of HV switchgear, hence high voltage circuit breaker ( CB) should have special features for safe and reliable operation. Faulty tripping and switching operation of high voltage circuit are very rare.
What are the components of switchgear?
Components of Switchgear. Switchgear essentially consists of switching and protecting devices such as switches, fuses, isolators, circuit breakers, protective relays, control panels, lightning arrestors, current transformers, potential transformers, auto reclosures, and various associated equipment.
