Application for High-Voltage Switchgear

2016-12-06 17:52:28 | 日記
High-voltage switchgear is mainly used for power system (including power plants, substations, transmission and distribution lines and industrial and mining enterprises and other users) control and protection, either according to the power grid operation needs to be part of the power equipment or line into or out of operation, Power equipment or line failure will be part of the fault from the power grid quickly removed, so as to ensure the normal operation of the non-fault part of the power grid and equipment, operation and maintenance personnel security. Therefore, the high-voltage switchgear is a very important transmission and distribution equipment, its safe and reliable operation of the power system safe and effective operation is very important.
(1) elements and combinations thereof
Including switchgear, recloser, breakers, load switches, contactors, fuses and combinations of the above-mentioned components, including switchgear, fuse-switchgear, contactor-fuse (FC) Load switch, fuse-type switch, open-type combination of electrical appliances.
(2) complete sets of equipment
The components and their combination with other electrical products (such as transformers, current transformers, voltage transformers, capacitors, reactors, surge arresters, bus, inlet and outlet casing, cable terminals and secondary components, etc.) Combined in the metal enclosed shell, with a relatively complete use of the product function. Such as metal-enclosed switchgear (switchgear), gas-insulated metal-enclosed switchgear (GIS) and high-voltage / low-voltage prefabricated substations.
