JYN2-12 removable metal-enclosed switchgear
Classification:
Overview YN2-12 type removable metal enclosed switchgear (hereinafter referred to as switchgear) is an indoor metal enclosed switchgear suitable for receiving and distributing electric energy in a single bus system of 3-12kV, 50Hz and rated current of 630-2500A. It has five anti-locking functions. The switchgear conforms to the national standard GB3906 "3-35kV indoor AC metal-enclosed switchgear" and the International Electrotechnical Commission IEC298 "AC closed switchgear and control equipment" and other relevant standards. Features This type of switchgear is a spaced-apart metal-enclosed switchgear. The structure is divided into two parts: cabinet and removable parts (referred to as trolley). The cabinet body and the trolley are welded by thin steel plate components with high mechanical strength. The cabinet is divided into four parts: handcart room, bus room, cable room and relay instrument room by grounding thin steel plate or SMC and DMC high strength flame retardant engineering plastic insulation board. The switch cabinet has a "five-proof" mechanical locking device to prevent misoperation accidents. Normal use ambient conditions ● Ambient temperature: upper limit. 40 degrees C, lower limit. -10 ℃. ● Relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%. ● Altitude: less than 1000 meters. ● Earthquake intensity: less than 8 degrees. ● There is no fire, explosion hazard, serious pollution, chemical corrosion and severe vibration.

Product Details
The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc. Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry and textile, factories and mining enterprises and residential areas, high-rise buildings and other different places. It mainly includes high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic coincidence and segmenter, high-voltage operating mechanism, high-voltage explosion-proof distribution device and high-voltage switch cabinet.
Correct Selection of Breaker Breaking Capacity
On the primary system diagram, the selected circuit breaker, indicating the circuit breaker model, rated working voltage and rated working current, must also be selected for the breaking capacity of the circuit breaker. With user drawings, the breaking capacity of the circuit breaker is not selected, which makes it difficult for the manufacturer to carry out engineering design. The breaking capacity selection should be based on the system short-circuit parameters. If the manufacturer does not understand the system short-circuit parameters, it is difficult to make the correct choice. There are also some user drawings, regardless of the system short-circuit parameters, blindly select high-break parameters, resulting in unnecessary waste of funds. The correct choice of breaking capacity is very important, not only to ensure safe operation, but also to consider reducing product costs.
