KYN28A(GZS1)
// Product Advantages
Cabinet: It is made of high-quality aluminized zinc-coated steel sheets or galvanized steel sheets, which are processed and bent by numerical control equipment and assembled with bolts. The cabinet is divided into four functional compartments by grounded metal partitions, namely the circuit breaker compartment, the main busbar compartment, the cable compartment, and the relay and instrument compartment.
Handcart: They can be classified into circuit breaker handcart, voltage transformer handcart, isolation handcart, metering handcart, etc. according to their purposes. Handcarts of the same specifications are interchangeable. The handcart in the cabinet are moved by a screw propulsion mechanism. There are isolation, test, and working positions in the handcart compartment, and each position is equipped with a positioning device.
Breaker: Generally, vacuum breakers are configured, featuring long service life, high parameters, low maintenance requirements, and small size. The number of operations of the breaker can be displayed on the counter on the panel. It is also equipped with a display and controller, showing mechanical status (red, green) of opening and closing, as well as the energy storage indication of the energy storage motor, among other information.

// The following are the common application scenarios of KYN28A (GZS1)-12 Armored Removable AC Metal-Enclosed Switchgear:
1. Power Plants and Thermal Power Plant Distribution Systems
It is suitable for the auxiliary power system of power plants and the low - voltage power distribution section of thermal power plants. Generator outgoing line cabinets, auxiliary transformer cabinets, etc. can be installed to protect and control power generation equipment, ensure the safety of power distribution during the start - stop and operation of the units, and meet the requirements for high - reliability continuous power supply.
2. Transmission and distribution networks in substations
As the core power distribution equipment in substations, it is used in the scenarios of incoming lines, outgoing lines, and busbar sectioning at the voltage level of 10 - 12 kV. It supports ring - network power supply and radial power supply modes. In cooperation with comprehensive protection devices, it can quickly isolate fault sections, improving the power supply stability and automation level of the power grid.
3. Self - supplied power plants and distribution rooms in industrial enterprise
It is widely used in self - supplied power plants and high - voltage power distribution systems of industrial enterprises such as metallurgy, chemical engineering, and mining. It is compatible with functional units such as motor control and capacitor compensation. It can withstand dust and vibration in the industrial environment, support frequent operations, and ensure stable power supply for large - scale equipment.
4. High - voltage power distribution in commercial and civil buildings
It is suitable for substations in high - rise buildings and commercial complexes. As the main equipment of high - voltage distribution cabinets, it controls the power supply for floor distribution boxes, fire - fighting equipment, and elevator systems. It has a complete set of five - prevention functions, reducing the risk of human misoperation and meeting the fire - safety regulations of civil buildings.
5. New energy power generation access systems
In new energy power stations such as wind and photovoltaic power plants, it is used in the high - voltage power distribution section of box - type substations and step - up stations. It meets the requirements of frequent switching of new energy power generation equipment, supports linkage with intelligent monitoring systems, and realizes the efficient access of distributed power sources and the optimization of power quality.
6. Municipal engineering and infrastructure
It is suitable for power distribution centers in municipal projects such as airports, subways, and sewage treatment plants. It can be installed in relatively humid or dusty environments. Its metal - armored structure provides an IP4X protection level, ensuring continuous power supply for transportation hubs and urban lifeline projects.
// FAQ
