KYN2 8-24 Metal enclosed middle mounted switchgear
Product description
KYN28-24 Indoor metal-clad withdrawable switchgear(hereinafter short as switchgear)is a complete power distribution device for 3.6~24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with VD4 from ABB,3AH5 from Siemens domestic ZN65A,and VB2 from GE, etc.,it is truly a power distribution device with good performance.
In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.

Operation conditions

◆ Normal and special use conditions

Ambient temperature: the highest temperature is +40℃. The minimum temperature is -15℃, and the average value measured in 24h is not more than 35℃.

The humidity conditions are as follows:

——The average relative humidity of the day is not more than 95%, and the mean monthly relative humidity is not more than 90%.

——The average daily vapor pressure does not exceed 2.2 kPa, the average monthly vapor pressure does not exceed 18 kPa.

Condensation occurs occasionally under such conditions.

Altitude not exceeding 1000M

The ambient air is not significantly polluted by dust, smoke, corrosive and/or combustible gases, vapors or salt sprays.

Vibration or ground motion outside the switchgear and control equipment is negligible.

The amplitude of electromagnetic interference induced in the two system does not exceed 1.6K.

◆ Special conditions of use

The company and the user can negotiate and reach an agreement on special operating conditions when they are used under normal environmental conditions beyond the stipulations of GB/T11022.

To prevent condensation, the switchgear is equipped with a heater, which should be put into use when the switchgear is in a standby state. When switching devices are running normally, they should also pay attention to the heater.

Technical parameters



Structure and working principle
◆ Structure description

KYN28-24 switchgear is made up of two parts: the cabinet body and movable part (commonly known as handcart). The cabinet is divided into several functional compartments with metal partitions, such as bus bar room, circuit breaker room, cable room and relay instrument room.

The movable parts of switchgear can be configured with vacuum circuit breaker handcart, voltage transformer handcart, lightning arrester handcart, isolation handcart and flame breaker handcart.
