KYN61
// Product Advantages
By adopting composite insulation methods, optimizing electrode shapes, and improving electric field distribution, the entire cabinet structure is compact, effectively reducing the occupied area;
The “five prevention” functions are complete, and the operation is safe and reliable. There is a mechanical interlocking device between the handcart, circuit breaker, grounding switch, and rear door of the cabinet to prevent accidental operation. At the same time, a padlock can be installed on the valve pushing mechanism to prevent accidents caused by non professionals accidentally opening the valve when the handcart exits the cabinet;
Circuit breakers, grounding switches, and other operations can be carried out under the condition of cabinet door closure, fully achieving door closure operation;
The cabinet body is made of high-strength and corrosion- resistant imported aluminum zine coated sheet metal, which is CNC sheet metal processed and formed. It is connected by high-strength bolts, nuts, and rivet nuts. The entire cabinet body is welded free, with precise dimensions and good stiffness, ensuring the interchangeability of handcart;
Using a ball screw propulsion mechanism, the handcart can be pushed (exited) effortlessly and smoothly;
Easy to operate and maintain, users only need to master the operation method proficiently through the user manual, understand its precautions, and do not need specialized training.

// The following are the common application scenarios of the KYN61-40.5 Movable Metal-clad Enclosed Switchgear:
I. Transmission and Distribution Scenarios in the Power System
1. Substations (Voltage Levels of 35 kV and Below)
As the core power distribution device in substations, it is used for the connection between transformers and transmission lines, load distribution, and circuit protection. It is suitable for the indoor power distribution compartments of outdoor substations or the overall power distribution systems of indoor substations, and supports wiring methods such as single busbar and single busbar sectioning.
2. Switching Stations and Ring Main Units in Urban Distribution Networks
In the high-voltage power distribution networks of urban core areas, as the node equipment of the cable ring network, it realizes the flexible switching and distribution of multi-circuit power supplies. It is suitable for indoor switching stations with compact spaces. The modular design facilitates installation and expansion, meeting the needs of "miniaturization and intelligence" of urban power grids.
II. Power Distribution Scenarios in Industrial Enterprises
1. Large Industrial Plants and Industrial Parks
It provides equipment support for the 35 kV high-voltage power distribution systems of enterprises such as metallurgy, chemical engineering, coal, and machinery manufacturing, and is used for the power access and distribution of main power distribution rooms and workshop substations. Microcomputer protection devices can be configured to achieve overload, short-circuit, and grounding fault protection for industrial loads such as motors, transformers, and capacitors, ensuring the stability of continuous production power supply.
2. Special Environments in Mines and Petrochemical Industries
In underground mines (derived models that meet explosion-proof requirements are needed) or petrochemical plant areas, to deal with harsh environments such as a large amount of dust, humidity, and corrosive gases, the metal-enclosed structure provides higher protection performance. It supports dual-power switching to ensure the uninterrupted power supply of key equipment (such as mine ventilation fans and the power supply for chemical reactors).
III. New Energy and Power Generation Scenarios
1. Step-up Stations in New Energy Power Generation
In the 35 kV step-up stations of wind farms and photovoltaic power stations, as the connection equipment between box-type transformers and main transformers, it realizes the collection and step-up transmission of new energy power. It meets the frequent switching requirements of new energy equipment. The circuit breaker has a high short-circuit breaking capacity (such as 40 kA), meeting the protection against the impact current output by wind power and photovoltaic inverters.
2. Auxiliary Power Systems in Power Plants
It is used in the 35 kV/10 kV power distribution systems within thermal power plants and hydropower plants to supply power to auxiliary equipment such as steam turbines, boilers, and circulating water pumps, ensuring the reliable operation of the main power generation equipment.
IV. Transportation and Infrastructure Scenarios
1. Power Supply Systems for Rail Transit
In the traction substations of subways and high-speed railways, as 35 kV incoming line cabinets or feeder cabinets, it provides highly reliable switch protection for the catenary power supply system, supports the function of rapid reclosing, and meets the load fluctuations caused by the frequent starting and stopping of trains.
2. Urban Utility Tunnels and Underground Projects
In the power distribution systems of urban utility tunnels, tunnels, etc., the moisture-proof and anti-condensation design of the equipment (such as installing moisture-proof heaters) can adapt to the long-term humid environment, ensuring the safety of the power supply for urban infrastructure.
V. Commercial and Public Building Scenarios
1. Large Commercial Complexes and High-rise Buildings
As the core equipment of the 35 kV main power distribution room in super high-rise buildings or urban complexes, it realizes the distribution and monitoring of high-voltage power supplies, supports networking with the intelligent power distribution system (SCADA), and meets the needs of real-time load monitoring and remote control.
2. Key Places such as Hospitals and Data Centers
In scenarios with extremely high requirements for power supply continuity (such as hospital operating rooms and data center server clusters), by configuring dual busbar or bypass busbar solutions, maintenance can be carried out without power interruption, ensuring the continuous power supply of first-level loads.
VI. Emergency and Backup Power Scenarios
1. Backup Power Switching Systems
Cooperating with diesel generators and energy storage devices, it quickly connects to the backup power supply when the commercial power is interrupted, which is suitable for scenarios with extremely high requirements for power supply reliability such as airports and radio and television centers.
2. Temporary Construction and Emergency Power Usage
The modular structure is convenient for disassembly, assembly, and transportation, and can be used as the core equipment of temporary substations to meet the temporary high-voltage power distribution needs of engineering construction, disaster relief, etc.
// FAQ
Q: What are the applicable voltage levels and the range of rated currents of the equipment?
A: The rated voltage of the KYN61-40.5 switchgear is 40.5 kV, and it is suitable for the 35 kV power system. The rated currents cover 1250 A, 1600 A, 2000 A, 2500 A, and 3150 A. The rated short-circuit breaking current can reach 31.5 kA or 40 kA, meeting the needs of power distribution systems with different capacities.
Q: Can the equipment be used in a humid or dusty environment? What is the protection level?
A: Yes, it can. The equipment adopts an armored metal-enclosed structure, and the protection level reaches IP4X (protection against the intrusion of solid foreign objects).
Q: Is there a need for special modification when the equipment is used in underground mines or chemical plant areas?
A: The conventional model is suitable for general industrial environments. If it is to be used in underground mines (an explosion-proof certification is required) or in strongly corrosive chemical scenarios, customized products such as explosion-proof types (increased-safety enclosures) or anti-corrosion types (made of 316 stainless steel + fluorocarbon paint coating) can be provided. It is necessary to inform the environmental parameters in advance (such as gas composition and dust type) for targeted design.
