Roselectronics: High-voltage switches

2022: Development and start-up of production of circuit breakers with energy storage

Holding Roselectronics"" Rostec State Corporation announced on October 28, 2022 about the development and launch of the production of switches equipped with magnetic drives with a drive. energy In the event of an emergency shutdown electric power , the switch performs automatic re-actuation (AFB) in 0.3 seconds, which allows to minimize time the interruption of power supply to consumers. The equipment can be used in network enterprises, enterprises, metallurgy heavy,, and. mechanical engineering chemical oil processing mining industry

These high-voltage switches, created by the Contact NPP (part of Roselectronics), are used in distribution networks. The devices have low current consumption when operating as part of switchgear and switchgear, which serve for receiving and distributing electricity to consumers.

The use of energy storage allows you to control switches even in the absence of operational current. The development will make it possible to significantly facilitate the operation of operational power supply circuits and increase their reliability.

The technical solutions used in the development of these switches allow the use of products in networks with a low-current power supply. The devices will compete with switches both with a magnetic latch with power supplies and switches with spring drives. The equipment has standard dimensions of the switching device and provides high reliability. Circuit breakers have passed a full cycle of tests, including climatic ones, and have all the necessary certificates. The capacity of the enterprise allows to produce up to 200 switches per month, said the executive director of NPP "Contact," Alexander Yudin.

Current consumption by the VBM-10-20 version switch in time energy storage is not more than 1A at voltage 220 V and not more than 2 A at voltage 110 V.
