1. Exchange renewal scenario: intelligent upgrade of old equipment
In a large number of medium and low voltage switches in operation in Russia, it is difficult to satisfy traditional electromagnetic converters because of their large size and complex installation for modernization. The split core current transformer russia with open and closed design can be integrated directly into existing buses or cables without having to disassemble the base circuit, which will become a key component for the intelligent modernization of switchgear.
1.1 Typical applications of retrofit current transformer for switchgear
For replacement devices that have been in operation for more than ten years (such as KYN28, GGD, etc.), replacing the entire cabinet means long power outages and high costs. After adopting the retrofit current transformer for switchgear, the renewal cycle has been shortened from several days to several hours, and there is no modification of the Original lines are required. In this scenario, the split core current transformer russia helps system integrators complete digital transformation without replacing tanks. This significantly reduces the overall cost of the project.
2. Substation scenario: uninterrupted installation to ensure continuous power supply
The restoration of the current control of the substation often encounters a harsh restriction of the "inability to cut off the energy". Whether it is a 10 kV distribution room or a 35 kV double station, any supply interruptions may affect the production in the sewerage or the electricity consumption of the apartments.
2.1 On site value of current transformer without power shutdown
In the sectors of continuous production, such as oilfields and metals in Russia, losses from supply interruptions are calculated in minutes. The current transformer without power shutdown allows operation and maintenance personnel to safely install sensors when the basic circuit is active. The empty structure of Roche's screw rule eliminates the danger of secondary open high-voltage circuits and outputs of millivolt signals to truly "map and use" to achieve. The project of the substation in Siberia uses a split core current transformer russia, to end the repair of 12 cabinets without interruption in the power supply and achieve zero load.
3. Integrated energy distribution system scenario: Efficient distribution in small space
The interior of distributor containers (such as the series ЩО-70 and ПР-85) is very narrow, and a conventional CT can often not be mounted due to its large size or affects the heat distribution and lines.
3.1 Compact split core current transformer releases cabinet space
The compact split core current transformer contains only five sizes of a conventional CT and can flexibly adapt to straight, round or cable-shaped bus strings. The integrated design of the casting has a degree of protection of IP67, suitable for very cold environments -40 ℃, and is lifelong maintenance-free. In the energy distribution system integration project, split core current transformer russia has introduced a shared space for intelligent control units, wireless temperature meters and other auxiliary devices, which integrate seamlessly with energy control systems and energy control systems.
4. Conclusion: a sensor includes three basic scenarios
From the renewal of switches to uninterrupted assembly in substations to the distribution of integrated distribution containers, the split core current transformer russia is based on its Open and closed construction, the free use of energy and the advantages of small sizes have become the ideal choice for energy conversion projects on the Russian market. The main focus of this article is the analysis of the retrofit current transformer for switchgear, The three main possibilities of the compact split core current transformers are decision elements, Purchasing managers and engineers are more interested in real projects.
