24kV Indoor metal-clad with drawable MV Switchgear 24kV Indoor na may metal-clad na may drawable MV Switchgear

Paglalarawan:

Ang China KYN28 indoor metal-clad na may drawable switchgear (ditoon pagkatapos ay maikling tinatawag bilang switchgear) ay isang kompleto na device para sa power distribution para sa 3.6~24KV, 3 phase AC 50Hz, single bus sectionalized system. Ito ay pangunahing ginagamit para sa power transmission ng middle/small generators sa mga power plants, power receiving, at transmission para sa mga substation sa power distribution at power system ng mga factories, mines, at enterprises, at pagsisimula ng malaking high-voltage motor, atbp., upang kontrolin, protektahan, at bantayan ang sistema. Ang switchgear ay sumasaklaw sa IEC298, GB3906-91. Bukod sa paggamit nito kasama ang lokal na VS1 vacuum circuit breaker, ito ay maaaring gamitin kasama ang VD4 mula sa ABB, 3AH5 mula sa Siemens, lokal na ZN65A, at VB2 mula sa GE, atbp. Ito ay talagang isang power distribution device na may mahusay na performance.

Upang matugunan ang pangangailangan para sa wall mounting at front-end maintenance, ang switchgear ay mayroong espesyal na current transformer, kaya ang operator ay maaaring i-maintain at inspeksyunin ito sa harap ng cubicle.

Mga teknikal na parametro:

Ano ang mga teknikal na parametro ng indoor metal armored traction medium-voltage switchgear?

Rated Voltage:

• 24kV: This parameter determines the insulation level and other related electrical performance design criteria for the switchgear.

Rated Current:

• Common rated current specifications include 630A, 1250A, 1600A, 2000A, 3150A, etc. The specific value should be determined based on the size of the connected load to ensure that the equipment can safely and stably carry and distribute electrical power.

Rated Short-Circuit Breaking Capacity:

• Typically ranges from 20kA to 31.5kA. This parameter reflects the switchgear's ability to interrupt short-circuit currents. The rated short-circuit breaking capacity must be greater than the maximum possible short-circuit current in the power system to ensure reliable interruption of fault currents during a fault, preventing the accident from escalating and maintaining the safe and stable operation of the power system.

Protection Class:

• Generally, the protection class is IP4X or higher. The protection class indicates the enclosure's ability to protect against the ingress of external objects and water. An IP4X protection class prevents the entry of solid objects larger than 1.0mm in diameter into the switchgear, as well as accidental entry of foreign objects or tools, thus effectively protecting the normal operation of internal electrical components.
