KYN28-24 Type Indoor Metal-Clad Withdrawable Switchgeaz
General:
ZS1 indoor metal-clad withdrawable switchgear(hereafter short as
swithgear) is a complete power distribution device for 3.6~24KV, 3
phase AC 50Hz, single bussectionalized system. It ismainlu 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 be used with VD4 from
ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc. It is
truly a power distribution deviece with good performance.

Switchgear Structure:
1. Switchgear is composed of cubicle and removable parts (so called
trolley). The cubicle is separated into several functional
compartments by metal sheet, including busbar compartment, circuit
breaker compartment, cable compartment and low voltage
2. Switchgear removable parts can be equipped with VCB trolley,
voltage transformer trolley, lightning arrester trolley and fuse
trolley.
3. Pressure relief devices are installed above trolley compartment,
busbar compartment and cable compartment. Special sealing ring on
the door seals the panel door.
4. In case of faults inside the compartments resulting in arc, the
pressure is going up inside the switchgear and the pressure relief
equipped on the top will open automatically, to release pressure
and high temperature gas. In this way, it can ensure the safety of
operating staff and the switchgear.
